I've always looked at the 254 and 968 elevators and wondered how'd they do that. IMO it looks like the best way to do an elevator if you can machine the bearing blocks and if you can weld the aluminum. We used 80/20 the is year an it worked great for use but I noticed that the pads had a tendency to sag at full extension towards the end of the season. Also 80/20 is some heavy stuff (and that's putting it nicely

). Did you notice that the teflon pads wore down on your old elevators after a lot of use? I'd really like to experiment with an elevator like this and it seems like the teflon pads are a more feasible option for us.
Thanks a lot for discussing your designs here as well, I know 254 and 968 and even 60? when they were with 254 back in the day have inspired more robots then you'll ever be able to count.
