Bob Shortridge and Phil Thompson talk about Lignum Vitae's work at the Osage hydropower project, qualities that make the its self- and water-lubricated bearings unique, and the advantages the company's wooden bearings can offer over synthetics.

The great things here at -- division international 2013 is the opportunity or. Great dialogue among service and product providers as well as play -- -- and I just happen by that they would have let -- vitae and then met up with my good friend Bob short -- here than her like you know -- and he had felt constant from the and -- plant in. And by Ameren in Missouri. And they've got a great story to tell so and Bob you -- telling me that in the last year you'd gone around the country and -- -- that a lot of Hydro plants. Tell me a little bit about your quest there. Yeah you know what was kind of exciting this year we. I had the opportunity to -- to several plants that. Displayed 45 to 85 years of where are on the same parents. Which I found this extraordinary. And when I do realize that they had this kind of long to be against them I start studying this terrible closer to see why did this material last so long why did this particular grade of material and it came to understand that it was the it was in the -- of the material. It and to be not a year and denser and harder than other -- that it didn't play so. With that idea the thought. I was looking for an opportunity with a plan that head. Issues maybe with an inordinate. Where pattern to it. And -- I got a call from fill it Osage and yet that very condition. Taken place and you know from that breeze started to negotiate how we -- going to see this through Oakland and I got in -- in the ties invitation to dosage and and inspected it and we came up with a plan to two but in this new configuration into the into the -- -- states -- -- -- very gracious to allow us to to do a little bit of experimenting but it was an experiment with. Maybe 85 years of -- history behind it's I felt. It wasn't it was exactly Guinea pig situations. But again they they allowed this to happen. And it turned out via. Very good. -- -- It now Bob you've got this really curious because we want to know what your problem lets Philip see each plant there and misery. Well actually I started out with with one unit that handy a really -- Iberian war. Normally the bearings on the tighter terms vertical machines can last maybe ten years between adjustments. I had a unit that I could you only get about three months where out of the -- -- had to make an adjustment so we've been fighting this for five years actually. We had a little experience in in changing orientation -- materials and getting a little longer life out of that so I ran across. At. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- And it. It was just eating berries -- terribly. It's had a lasting -- years. I eventually got some that I can only run the unit for about 45 minute test before it -- completely destroy the bearings so after we completed the the league about a change out on. Our main -- six we decide to go ahead rather mature along unit for. I had a pretty good confidence that it would work I mean six that not a lot of confidence that would work I mean for. The -- but the material in and and we put it in kind in the orientation that Bob recommended and the unit has now been run for about four months and we've seen no -- -- at all performance and really made nor the changes of just changing very that your. They're going from 45 minutes -- four months and running neck in. Yeah and in and really I don't at this point expect the room to see any significant where at all -- I think we found really a permanent fix the alternative that we're looking that was replacing the -- -- On that particular machine which was gonna end up being about a quarter million dollar investment and repair so. Very -- performance out of during the -- and that the natural wood and really I think it goes to the point that -- the -- guys really knew what they were done because that was the original material that was specified back in 1929 for those machines. So. And -- one of the things that I think you were showing me earlier and and I think we're gonna actually be able to show the viewers here. Is the precision. At the way those hearings are operated in terms of the did the variants that. Right right did that was that that the part that was that was really used to to learn more about -- -- -- we'd like to think that. The material can be adjusted to zero and other which that -- would would really mixes this internal different than any of the other. Composite materials is is that it doesn't -- -- into the shaft which means that you can grab the -- you can hold it into position and force it to since been true and straight so and and we've learned this -- several plants where there's that there's -- condition going on around the country against all over the place where concrete is concrete dams are growing. And some of them make make -- go out aplomb and by going out of Islam they they they're they're forced to either fix it. -- a total rebuild on the -- or. Forced the shaft -- so we are we found that that this material could actually grab it. And push it into place and and hold its. So was this this this we found that 75 megawatt plants it was a it was a good good -- unit in and and really neat to phenomenon that we that we discovered in this. Let's watch that video now it. -- so -- one of the things that I'd really like to know after watching them video is -- -- in this particular and Maine guide Mary water implicated -- guide -- Tell me why you -- -- this particular line. We had we had some experience with some of the synthetic materials and we just did not get you'd Wear out of those. So as we started looking around we came across this this natural -- bring material. And and we started looking in at the fact this stuff has been used in machinery and -- -- machinery since the late eighteen hundreds. I was specified by. Thomas Edison in one of the first our houses that he built. So you know we thought and it was actually specified in the 1929 drawings that we -- from stone and Webster and -- Chalmers on -- -- machines so we started asked the question. Why weren't we use the same material again it was good enough. For all those years both turned out as we start in the research turns out that the -- was she so predominantly all the way up through work to that it the supply was almost exhausted its owners began to transition into you the synthetic materials mostly with pretty pretty good success. But we found the problem units like the ones that we had the synthetic materials just weren't holding -- And as we talked with with Bob it -- mean by that we found out that that you had experience with. Similar kinds of situations with other customers he provided me with a nationalist account to access article customers and almost all of them. Had the same experience that we did they had synthetic materials. They had problems they return to lick about it and they get success and that's really our story as well let's kind of the journey that we've taken. That pretty much -- at all I think I appreciate you taking time it's great. Have you that -- here at tighter tension and -- -- story it started here and it looks like it's continuing. And they think residents amendments. Mark Barnes reporting for -- world dot com at -- vision international.
