Hey guys this is kind of a dumb post and I already have several solutions, but hear me out.
I have 2x boardnamics idler mounts on the precision hangers, 97mm ABEC 11 wheels, and the new Maytech motors from the Fiori group buy. I am trying to set up the mechanics of it and it is not quite working out. I have a 40T wheel pulley and a 14T motor pulley, the belt that I have to use for it is 320mm, which is what was suggested on the website and by several other people, however, I have run into some issues.
I cannot get the idler tight enough without crashing into the wheel. I don’t think I am doing anything wrong but it just doesn’t make sense that 320mm would be suggested as a size when even with the idler completely tightened, the belt is still almost too big. Am I just screwed here, needing to buy a shorter belt? Or should I pursue a different solution?
Couple solutions: Buy new belt - would need return the belts, takes time.
3d print an idler expander (diameter) - really not the prettiest solution.
Flipping the motor pulley around doesn’t make any difference and the shaft of the motor is already too short for the pulley to grip with the allen screws, so I was going to need to loctite it anyway
Pressing the belt to almost the right tension, except the idler hits the wheel
Definitely not tight in this photo either, idler crashing into wheel
Pressing to right tension without the idler on - clear in this shot that the belt seems to be too long
This clearly isn’t the solution either (flipping the pulley so that the allen screws grip the shaft) The overhang between the pulleys is crazy, will be shown further with the idler
Obviously you can’t run the idler like this
Using all the washers from the other idler to put it in the right spot, still crashes into the wheel.
