Instead of 1 90 deg bend how about 2 45 deg bends.
You can also design in a radius bump bend in which a series of small tangent bends together form a large radius bend.
You guys ever wonder how Team 67 can get away with using the light gage round aluminum tube and why it is so strong?
Our team is looking at making a gear drive as well and I had a few questions having never built one.
Dustin stated in an earlier post that you can use the 1/2 inch tubing that Vex Pro sells and run 1/2 inch hex broached gears on it with no issues. Can anyone else verify this? It’d be nice if we didn’t have to shave a few thousandths off the tubing to have the gears spinning with little to no resistance due to friction.
Using this setup would mean running 1/4 inch bolts through the tubing. Does anyone have recommendations on the type of fastener to use & what hardness grade? I’ve never ran anything smaller than a 1/2 inch bolt on a drive shaft so I’m curious what others have used.
Thanks for posting these designs, I know I’ve learned a lot from reading through these threads.
