Re: pic: Linear bearing rails: the Cheesy RAWC way
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:D ). 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. |

I think the key word here is "professional welder," I could best be described as a "professional n00b" seeing how all I weld are the team robots... ;) Thanks for the tips though. We'll keep that in mind if we ever do it again. |

Were the bearings attached with simple bolts or shoulder bolt? If you just used plain bolts then it would be much cheaper.

Regular screws with nylon washers so the outer races could spin freely.

I was hoping regular bolts was the answer. That will make things much simpler.
