100 Jahre Bergsturz Sandling 100 years of the Sandling landslide 100 years ago, in September 1920, a massive landslide occurred in the West Face of Sandling. The so-called "Pulverhörndl", around 200 m high, which split off from the West Face of Sandling in a landslide in 1765, collapsed in September 1920. In May 1907 the summit was first climbed. Namely by the Ischl mountain guides Mathias Röchenbauer and Alois Wazinger. A cairn visible from afar at the summit testified to your first ascent. In the years that followed, the summit was climbed more often and the summit stone man soon gathered cards from the best Upper Austrian climbers. Der Sandlingturm, aufgenommen von Franz Maier, 1915. The west side of the Sandling summit with the Pulverhörndl in front of the landslide and the old scree heaps. In anticipation of the catastrophe, the builder, Weinzierl, had the pictured house of the alpine grass garden relocated to the foot of the Raschberg to the west of the stream. The western face of Sandling Peak after the landslide. On the far left, the seating area separates parts of the old scree heap from the new giant screed. About the geology: The Sandling has always been a troubled mountain . Namely, there is a high limestone on plastic Haselgebirge. And 1920 was a very wet, rainy year. This precipitation penetrated through the fissured and waterlogged limestone and marl and softened the underlying clayey layers. In addition, in the Ausseer salt mine in 1920 there were several "heavenly collapses", which destabilized the base of the rock masses of the "Pulverhörndl" just above. Beginning in the spring of 1920, salvos of rock pelted through the West Face of Sandling. Throughout the summer, much more frequently than usual, mighty boulders broke from the weathered rock and thundered down into the valley. Sandling rock stratification, Otto Lehmann 1926 The catastrophe: The sodden layers became this rainy summer literally squeezed out by the solid limestone marls and the limestone resting on them on the west wall. Then, on September 12, 1920, the unheard of happened . 20 people were still on the Vordersandlingalm. In the morning there was increasingly heavy rockfall from the west face, which was increasing constant noise. A climber who approached the summit from Altausse at 1 p.m. thought he heard train traffic, which surprised him because the railway lines were interrupted due to the heavy rain. The view down was already blocked by billowing clouds of dust. At about 4:30 p.m., even more violent boulder falls occurred, notably from the large rock pillars and pinnacles that towered between the Pulverhörndl and the face of the mountain. This was probably the time when the tower moved away from the wall, exposing the rocks wedged behind it. Cracks and faults became visible to the right of the tower, and the forest below slowly sank to the depths. At 5:30 p.m., a dairymaid noticed with horror that the Almboden was beginning to burst. Towards evening the mountain calmed down to some extent after most of the rocks between the Pulverhörndl and the wall had fallen down. Rock masses were no longer pressing on the back of the tower. But on the front, the pressure from the fallen rocks has increased considerably. The Pulverhörndl was now a bit shifted and isolated from the mountain up. But nobody took that as an opportunity to leave the Alm, only sleeping was out of the question. Around 11:00 p.m., a terrible roar began again, and a commotion was already felt in the ground. It was new moon and therefore pitch black, dust covered the pasture, lanterns could not illuminate anything. Now the fear was great: Valuables were hastily buried at the foot of the "Diebskögel" and the decision was made to leave the pasture and the cattle quickly. And not via the usual Almweg south along the Michelhallbach, but via the Raschberg to the Hütteneckalm. No one was harmed by this prudence! The Powder Tower collapsed on the night of September 13 with deafening thunder. Approx. 200,000 m3 of rock poured towards Michelhallbach. A large part of the overlying rock of the Sandlingalm was then torn down, creating a 400 m wide and 100 m deep shell-shaped crack. Incidentally, the entire Sandling was shaken, the entire western wall was speckled with light from stones that had broken out, and the trail through the western wall was then in a desolate condition. The Alm after the disaster: The four huts that were lifted and moved when the Almgrund was devastated. From the fourth by H. Joh. Reisenauer you can only see the ruins on the right in front. The "Diebskögerl" and the pressed and advanced Almgrund, which filled the meadow valley of the stream and leveled it. The objects (clothes and tools) buried at the foot of the "Diebskögerl" on September 12 were completely buried and have remained lost. The Mure: A huge debris flow moved down the valley. Only the southern part of the moraine mass, which had started to move, lost its connection and ended up as a mudflow. The upper, northern part was only loosened and sunk about 40 m deep into the trough created by the outflow of the Haselgebirge. On September 14th, a forest ranger from Bad Goisern, Paul Elsenwenger, was watching the debris flow from the foot of the Raschbergwand when the surrounding forest suddenly began to sway, the ground crunched, roots broke. He was only just able to save himself on the rocky valley wall! The Mure now filled the creek bed of the Michelhallbach and the large Zlambach for about 3.7 km and has dammed the spring streams that flow in on the east side to form two small lakes. 50 m / hour was the initial speed of the Murkopf and covered 2 km in the first 6 days. In the next 10 days he advanced another 1.2 km and in the next 15 days he came to a halt after a total of 3.7 km. View towards the southern part of the eastern tear-out niche. A shattered mound of lias marl covered with tree corpses. The rounded rock tower behind heralds the appearance of the Hallstatt limestone on the eastern slope. Tree corpses covered the debris flow. Reservoir at the mouth of a side stream. Just before it flows into the Zlambach, the Mure divided and an island was formed on which the handsome and spacious Leisling wooden room stood. This was dismantled in days of hard work and salvaged by hand. Witnesses of historical rockfall catastrophes can be found at the foot of the rock tower "Uh-sinnig Kira" (popular expression for "mad scream") at the Michelhallbach. Judging from archaeological excavations, there was already a rockfall accident there during Roman times (approx. in the 5th century AD) . There is historically reliable information about another catastrophe in the spring of 1546 , in which the surface facility of the small Michlhallbach salt mine was buried by a rock avalanche and claimed victims among the miners. The rock flow of 1920 also revealed evidence of this salt mine, namely a weak brine spring. It had been dyed red and exposed in several places.

Opening ceremony 7.9.2019 Via Salis - words of blessing from Franz Peter Handlichner: Dear Pernecker - dear men of the Mitterbergstollen interest group Dear Mr. Mayor, dear Mr. Executive Director Dear sisters and brothers in faith we are not god We are not rulers of the earth, but part of creation. The earth was there before us and was given to us. That is the message of the environmental encyclical "Laudato si" - With sentences like these, in the first environmental encyclical in church history, Pope Francis makes a radical break with an unfortunate tradition of exploitation that is based on a misunderstood interpretation of the Bible verse from the creation story Make the earth subject to you . As the Pope concedes, many people have grown up with the conviction that the earth is man's property and that man can therefore exploit its treasures. This is not the case – the Pope warns in clear words in “Laudato si”: “This is not a correct interpretation of the Bible as the Church understands it.” What sets this encyclical apart from others is the new location of man in creation - what is the place of man in creation? Man is not the ruler of the world, but only a part of the whole - the Pope makes clear. You too aptly express such a view of creation in the hiking guide that you created on the occasion of the inauguration ceremony of the VIA SALIS themed trail and the blessing of the Perneck village square: "The history of salt begins an unbelievable 250 million years ago with the deposition of the salt layers in the primordial sea , the so-called Tethys. This time is for us people of the 21st century. in the deepest darkness of history and we can only guess at it from the story of creation. The salt has always been present in the mountain and it required inventiveness, combined with courage and diligence, to make it usable for the people. Salt production has survived wars and revolutions, global economic crises and dictatorships and is still an economic factor in our region today. The rise of Bad Ischl from a village at the confluence of the Ischl and Traun rivers is based solely on the treasures of the mountain. This is thanks to many generations of hardworking, brave miners who have shown renewed courage, drive and tenacity in their dangerous work every day.” The small village square of Perneck and the VIA SALIS would like to remind us and future generations of this mining tradition. In his environmental encyclical, Pope Francis also expressed his great concern for the ecological balance and the world climate, which is a common global good that must be protected. The Pope criticizes the effects of environmental degradation, the consumerist throwaway culture and a capitalism that destroys social relations. The consequences of climate change hit the world's poor the most. Pope Francis is in solidarity with the poor countries that are demanding financial support from the rich countries in the international climate negotiations. And he calls for an ethics of international relations: “Because there is a real, “ecological” debt – especially between the North and the South – related to the imbalances in trade and their consequences in the ecological area as well as in the course of history disproportionate consumption of natural resources practiced by some countries.” It is fortunate that today's celebration is part of the so-called CREATION TIME takes place. If we walk the VIA SALIS, we also find the little mountain church. In 1751, Empress Maria Theresa ordered the construction of this little church: Luther's forbidden teachings were widespread among the miners - this church was intended to strengthen the Catholic faith among the working class again. Today, the little mountain church is a place where it is repeatedly evident how the ecumenical togetherness of the churches is lived as a matter of course. We thank our evangelical brothers Leopold senior, Leopold junior and Hermann Schiendorfer for their concern for the preservation of this church. I close, before the blessing of the new town square and Via Salis, with the words of the unknown miner who many years ago said: Ischl salt - God gave it, God preserves it. Franz Peter Handchner

02 The Emperor Franzens – Stollen Stud Name: Until 1808 "Lower Kaiser Franz - Stollen", then "Kaiser Franz Stollen" Emperor Franz II./I. (son of Emperor Leopold II), reigned 1792 - 1835 Struck: May 1, 1794 - together with Emperor Leopold - tunnels Length: 884m - 1834 propulsion set Altitude: 588 m The Kaiser Franz tunnel was struck together with the Kaiser Leopold tunnel on May 1, 1794. Around 1800, the Kaiser Franz tunnel had only been extended to 65 bars (77.7m). In 1809 the Court Chamber considered building a mountain house for Emperor Franz -- Stollen, for which 4244 fl. building costs were estimated. In 1811, the Verwesamt bought the building and garden area of 300 square meters from the owner Balthasar Gratzer for 150 fl Rent of 10 fl. In 1813 the Bergmeister Dicklberger was the first to move into the beautiful "Unteres Berghaus". The administration was in no hurry to drive the Kaiser Franz tunnel. From 1818 to 1822, tunneling was stopped altogether because the crew was needed to secure squeezing sections, and from then until 1830 the tunnel only advanced by 7 rods (8.4 m) into the field. It was now 743 Stabel (884.0m) long and still needed 1187 Stabel (1418.5m) to reach the salt line. It didn't come to that, in 1834 the administration stopped the construction of the tunnel altogether, with the intention of re-occupying it only after the completion of the Kaiser Leopold tunnel. It was not until 70 years later that the Kaiser Franz tunnel was replaced by the 1st blind horizon, which had been driven through the Distler shaft in 1904. From 1966 the "Franzberg - Haus" was used as an administration building for the ammunition depot in Perneck of the Austrian Armed Forces. During this time, a shooting range was installed in the Kaiser Franz tunnel and the tunnel was walled off after about 100m. The "Franzberg House" is now privately owned and cannot be visited.

07 The Empress Elisabeth – Stollen Stud Name: "Empress Elisabeth - Stollen" Wife of Emperor Charles VI, married on August 1st, 1708 in Barcelona Struck: 1712 Length: 750 m Altitude: 812 m The Empress Elisabeth tunnel was opened in 1712 in order to drive under the next higher Empress Amalia tunnel in order to be able to use the salt mountains below. After this stollen was first referred to as "New impact", it was given the name "Empress Elisabeth - Stollen" from 1730. In 1737, after 25 years of tunnelling, the salt limit was reached in the main shaft of the Empress Elisabeth tunnel. Next to the mouth of the tunnel there was a brick smithy and a dwelling for the hewers. But when the middle mountain house and the smithy were built next to the Empress Maria Theresia tunnel in 1783, the two now useless buildings at the Empress Elisabeth tunnel were demolished in the same year. Situation of the weirs in Elisabeth – tunnels around 1800: Length from the mouth hole to the salt boundary 620 mabel (739.0m), from there to the field location 440 mabel 4 hairpin bends and 6 usable weirs. A mountain thickness of 48m was chosen for the Elisabeth tunnel instead of the usual 30-35m. This made it possible to leach a more powerful salt mountain medium between the Ludovika and Elisabeth tunnels with less excavation effort. Because the mountains were too thick, the weirs arranged side by side spread so much during leaching that they threatened to intersect. The resulting, very large fortifications would have weakened the necessary hill forts so much that there would have been collapses. Great caution was therefore required during the leaching operation. In order to be able to avoid an unwanted intersection of the leach chambers, extensive intersection dams were built. The advantage of lower exploration costs for larger rock thicknesses was more than wasted. The water tunnel at the Elisabeth tunnel Due to the small thickness of the Haselgebirge massif in the upper horizons, the workers often reached out to the salt mountain limit, the exposed barren surrounding rock then led to fractures, which again triggered declines in the neighboring works. In 1839 the Nefzer plant in the Ludovika tunnel was lost as a result. Cracks in the sinkage of the Nefzer weir pointed to the imminent collapse of the mountain range above between the Freund works, which had already fallen on the Elisabeth horizon, and the combined weirs of Mohr and Schmied. The neighboring Wolfen weir in the Amalia horizon above had also fallen, so that the breach had already spread over three floors. So all measures to keep the united Mohr - and Schmied - work in the Elisabeth - horizon were still in vain. The destruction of such a large mining area put the Ischler Salzberg in a difficult position. Many workers had to be declared dead or celebrated in order to avoid the deeper decline and the Chotek - Kehr in the Ludovika tunnel, the Stüger - Schurf from Amalia - on Elisabeth - Horizon and Poniatovsky - Schurf from Elisabeth - on Ludovika - Horizon for derivation to be able to secure the looted waters. In 1849, 10 years after the collapse of the Nefzer weir in the Ludovika horizon, the sky of the combined Monsberg and Gerstorf works in the Elisabeth horizon also fell. The danger of new polluted water penetrating the Hasel Mountains and the collapse of the entire camp top threatened the existence of the entire Ischl salt mountain. All renovation work is described in the factory cleaning chapter. Situation of defenses in the Elisabeth tunnel around 1850: A total of 8 weirs, 1 pronounced dead and 1 usable. Freund - weir, Mohr - and Schmidt - weir (cut), Monsperg - and Gerstorf - weir (cut), Schlögel - and Wolfen - weir (cut); Quix - weir in operation around 1850.

The mountain saw at the old Maria Theresia Berghaus on the Ischler Salzberg: A saw was of great importance for every salt mine operation, since the mine operation required large quantities of "Ladwerk" (thick boards) for the expansion and the brine production. Therefore there was at least one, but usually several saws at each salt mine, which is why they were also among the oldest systems of the respective salt mine. Three saws are known on the Salzberg in Ischl: as the oldest, the Steinberg saw with the "Schafferklause", the Grabenbach - or Graben - saw built near the Ludovika tunnel and a third, from 1867, at the old Maria Theresia Berghaus. The following report will mainly deal with the latter saw, also known as the mountain saw, since the other saws and the associated Klaus systems were already dealt with in detail in the 2012 article by Franz Federspiel "News from the old Ischler Salzberg". Situation of the mountain saws on the Ischler Salzberg in the 18th century: Originally there were two plank saws on the Ischler Salzberg, the one on the Steinberg and the Graben saw below the Ludovika tunnel. The Steinberg saw was probably built immediately after 1563 with the start of salt mining in the Steinberg district. According to a note in Dicklberger's "Salinen - Geschichte" (volume 1, p. 388), the Steinberg saw existed before 1586. Figure 1: Steinberg - saw, conversion plan, 1842, archive Salinen Austria Figure 2: Steinberg - saw, ground plan, conversion plan, around 1845, archive Salinen Austria Due to the concentration of salt mining on the Pernecker salt storage and the associated deepening of the mining tunnels, the ditch - saw at the Ludovika - Berghaus was built. The exact date of construction of this saw, which was probably built around 1700, could not be found in the files. The first known documentary reference from September 25, 1769 provides information that the ditch saw and the associated hermitage were rebuilt after a fire at the estimated cost of 292 fl 52 kr. In the course of the conversion, a new storage hut was built along the entire length of the hermitage to store the saw cuts. The Graben - saw along with the associated hermitage had completely decayed again in 1816 and was rebuilt in the three following years. In 1839 the woodwork of the hermitage was rotten again, and the water wheel and the river also needed replacing. Figure 3: Ludovika Berghaus, site plan with ditch – saw, 1839, Archiv Salinen Austria Because of the high repair costs to be expected, in 1839 the Ischl mining operations manager at the time, Franz v. Schwind to leave the Graben saw at all and instead expand the Steinberg saw to make it more efficient. When converting the Steinberg saw, Schwind succeeded in increasing sawn timber production fourfold compared to the previous ones by using an overshot water wheel and a belt transmission in the gearbox, the first saw drive of this type in the monarchy. As a result, the sawn timber requirement of the entire Ischler Salzberg could be satisfied by the sole operation of the Steinberg saw. Figure 4: Steinberg - saw, design of an overshot water wheel, 1840, archive Salinen Austria The operation of the ditch saw should only have continued on a smaller scale, since the cost of bringing the cut goods from the Steinberg saw to the Pernecker tunnels via a specially created goods route was very expensive. For this purpose, Schwind replaced the desolate Grabenbach hermitage with a wooden weir in 1839. After the Graben saw burned down again in 1856, it was finally abandoned. Figure 5: Trench - saw with Ludovika Berghaus, 1838, Archiv Salinen Austria Figure 6: Connecting route Steinberg - saw to Graben - saw, 1838, Archiv Salinen Austria Figure 7: Ludovika Berghaus, site plan after digging – sawing, 1859, Archiv Salinen Austria Transfer of the Steinberg saw to the old Maria Theresia Berghaus: After the new Steinberg tunnel was shut down as the last tunnel in the Steinberg district in 1775, the Steinberg saw only produced for the Pernecker tunnel, which was much further down in the valley. After the final closure of the Grabenbach saw in 1856, the entire sawn timber requirement had to be laboriously transported from the Steinberg saw down into the valley. For this reason, the plan was made around 1865 to move the Steinberg saw closer to the Pernecker tunnels. Various installation sites were tested: at the Grabenbach at the confluence of the Gaisbach opposite the Josef tunnel and directly at the Sulzbach or, connected to the Sulzbach via a river, at the old Maria Theresia Berghaus. Figure 8: Project transfer Steinberg - saw to the Josef tunnel, around 1865, archive Salinen Austria In view of the focus of the advance in the Empress Maria Theresia tunnel and the short transport routes, the decision was made to transfer the saw to the old Maria Theresia Berghaus. The transfer of the Steinberg saw to the new location took place in 1867. By using the old saw drive and parts of the old saw building, the costs were kept low at a total of 669 fl 81½ kr. Figure 9: Transfer Steinberg - saw to the old Maria Theresia Berghaus, 1865, Archiv Salinen Austria Figure 10: Transfer Steinberg - saw to the old Maria Theresia Berghaus, 1865, Archiv Salinen Austria Figure 11: Transfer Steinberg - saw to the old Maria Theresia Berghaus, 1866, Archiv Salinen Austria Description of the gear mechanism of the plank saw: With the report prepared by Franz Kreuzhuber, manipulation pupil Ite class, on March 14, 1868, there is a precise, contemporary description of the historical saw drive: "Where there is great hydroelectric power, undershot water wheels of 2 to 3 feet in diameter and 5 to 6 feet wide are usually used to operate the board saws. Here an overshot water wheel with a diameter of 12 feet and transmission is put into operation. A cog wheel of 6 feet diameter fastened to the base of the water wheel sets a driving wheel and with it a pulley of 6 feet diameter, - this by means of belts a second pulley of 1 ½ feet diameter, with it a wooden flywheel of 6 feet diameter and at the same time an iron winch in motion, whose arm carries a rod connected to the sag container /: Saggatern :/ in its circumference, which pushes the same up and down in a vertical guide. The Saggatern is assembled from 4 pieces of wood in the form of a door frame, to the short pieces of which the Sagblatt is screwed. Since the saw always makes its movement in the same place, a device is necessary for advancing the object to be cut in proportion to the power of the saw. This device /: Sagwagen :/ is a twenty-seven foot long frame movable on a horizontal slide and fitted with small rollers for ease of movement. To move it forward, the sagger carries a 7-foot-long horizontal rod on the lower crossbar, the end of which is fastened in a shaft Rings with indentations /: Thrust ring :/ gives an impact to the surrounding wheel of 3 ½ feet in diameter and as a result rotates the same slowly. During the retraction of the former, a second bar holds the thrust ring against slippage. The wheel, which is attached to the iron base of the thrust ring and is similar to the drive wheel, pushes the sag wagon through the combs attached to it along the entire length according to the power of the saw. A second overshot water wheel, 6 feet in diameter, is used to move the sag wagon backwards to its previous position, the shaft of which winds around a rope which runs over a small pulley attached to the end of the track and is attached to the sag wagon. As the sag wagon moves forward, it unwinds the rope from the shaft again.” In the following plan, the original work of the Steinberg saw is shown as it is described in the report by Franz Kreuzhuber in 1868 during the transfer. Only the second, smaller water wheel for moving the sag wagon backwards was added at the new location at the old Maria Theresia Berghaus. Figure 12: Gear mechanism of the Steinberg saw, 1857, archive Salinen Austria Saw - Fluder: After the transfer, the service water for the saw was no longer fed through a hermitage, but through a small cushion in the Sulzbach. The "Schmiedenfluder" from the Sulzbach, which has existed since about 1825, could be used for this purpose. This river had to be built for the operation of the mountain forge, since from 1825 larger amounts of water were diverted from the Grabenbach via the water scour into the Elisabeth tunnel in order to be able to provide the service water required for the Laistauss flooding in the Maria Theresia tunnel. The amount of residual water in the Grabenbach was often too low for the operation of the forge at the Maria Theresia tunnel. The river was designed as an open wooden channel made from cut posts, 72 m long and 0.6 m wide. As early as 1881, the river, which had been renewed in 1867, had to be removed due to damage and a new river channel including water catch and wheel hut had to be installed at a cost of 719 fl 81 kr. to be erected. Further repairs of this kind on the fluder were necessary in 1891, 1905 and 1933. Figure 13: Saw - fluder, 1904, archive Salinen Austria Performance of the two saw - water wheels: The overshot water wheel for driving the gang saw had a diameter of 3.7 m and a width of 1.0 m, depending on the water pressure, an output of 4 - 5 hp; the also overshot water wheel ("mold wheel") for reversing the saw carriage with 1.7 m diameter and 0.75 m width 1 - 2 HP. Figure 14: Saw - water wheels, 1866, Archiv Salinen Austria Figure 15: Mountain saw with old Maria Theresia mountain house, around 1930, Kranabitl archive Figure 16: Mountain saw at the old Maria Theresia Berghaus (upper left edge of the picture), around 1930, Archiv Salinen Austria Modification of the mountain saw's gearbox: In 1879, a circular saw was installed in the firewood store next to the mountain saw to cut the firewood better. This circular saw could be operated directly from the saw by means of a transmission transmission. In 1893 the gearbox of the mountain saw had to be repaired because it was defective. The complex maintenance of the saw fluder and the water wheels as well as the low performance of the mountain saw caused the management to convert this saw to electric operation in 1950. For this purpose, a stationary electric motor with 750 rpm was installed. From the 325mm diameter drive wheel of the electric motor, a belt led to a 1550mm diameter pulley on the main shaft. A second belt drive was placed on the main shaft on the stream side, which connected a belt wheel with a diameter of 900 mm on the main shaft to a belt wheel with a diameter of 730 mm on the water wheel shaft to move the saw gate. Another belt drive on the uphill side enabled the forward and backward movement of the saw carriage by means of a chain. Figure 17: Conversion of the plank saw to electric operation, 1951, Archiv Salinen Austria In the course of the electrification of the saw drive, a side saw was also installed. For this purpose, the sawing building had to be structurally extended. Figure 18: Installation of the board saw, project 1949, archive Salinen Austria Figure 19: Erection of the Ladwerkstadel, 1951, archive Salinen Austria Closure of the sawmill: The mountain saw at the old Maria Theresia Berghaus remained in operation until the mid-1980s. Since the migration of the mining industry from Perneck to the new site at the Kaiser Franz Josef Erbstollen in Lauffen in 1989, the saw building has been empty. Figure 20: Last shift arrival from Perneck, June 29, 1989, archive Salinen Austria Figure 21: Mountain saw after the cessation of operations, 1991, Kranabitl archive Figure 22: Old Maria Theresia Berghaus with a mule saw in the background, 1991, Kranabitl archive Mountain saw revitalization: In the summer of 2020, the Mitterbergstollen interest group (IGM) set itself the goal of preserving and opening up the mountain saw as part of guided tours along the Viasalis circular route. The historic sawmill is well-preserved and, as a unique technical monument that is otherwise rarely found in the Salzkammergut, is particularly worthy of protection. The main elements of the saw gear, which dates back to 1847 and is made of wooden gears, have been preserved to this day. In 2021, with the support of Salinen Immobilien AG, IGM would like to secure the building fabric, set up a showroom in the area of the former sawmill and have the technical history of the saw documented as part of diploma theses.
