Go to Post My point is that there seems to be a trend in FIRST in which people are saying "who cares about the robots, let's inspire the students." What I'm saying is, it's the robots that inspire the students. - Chris Hibner [more]

Re: CIM motor shaft extender (adapter)



Here is one that we made to couple the CIM shaft to a quarter inch one, Sorry if you can't read it... It's my first attempt at drawing in paint ( don't have and CAD on the comp I'm on"


P.S. Change the .156" Diameter to whatever size the small CIM shaft is

Re: CIM motor shaft extender (adapter)
You didn't mention what bore you want on the wheels but I've used these before and liked them. http://www.npcrobotics.com/products/...at=22&mode=gfx We put them on a 220+ lb robot with NPC battlebot motors and the delrin hubs never gave a problem.

Re: CIM motor shaft extender (adapter)
darn, no 5/16 shaft hole. Things kinda changed, I have been looking around all day for a wheel just like the wheel chair ones, but no ball bearing, that I can weld too (steel to steel shaft) (not aluminum).

Re: CIM motor shaft extender (adapter)
Is there any specific reason for not using aluminum?
