Hi, New guy here.
Designing some bearing trucks and had a couple questions.
1 Does a bearing truck have to use 3 rollers, I would like to design one with 4 to ride a pipe? I was thinking one at say 12:00 oclock, one at 6:00 oclock, then just a little way back, one at 3:00 oclock and one at 9:00 oclock. 2 of the 4 would be adjustable. This would make it a lot easier to mount the bearing bolts as everything would be at right angles. This would be at each end so a total of 8 bearings for each slide.
2 What do you think about using gas pipe for the rail? I could slide a piece of rebar through the middle of the pipe and then pour fiberglass inside. No way in the world that would ever flex. I was thinking the pipe might be to soft on the outside?
Thanks in advance, and please go easy on me.
