Lite Hubs press into Lite Flite and Lectra Lite foam wheels (hobby aircraft wheels found at most hobby stores), providing a secure and very lightweight method of mounting a wheel onto a motor shaft. Lectra Lites with 1/8" bores can be easily drilled to 5/32" to fit Lite Hubs (#22 drill bit is best).
A ring of Gorrila super glue is required for a permanent fixture (we have found it works better than Cyanoacrylate or CA glue). Insert the Lite Hub into the wheel part way. Apply glue to the joint then flip the wheel over and press it down onto a hard surface.
The Robot Marketplace
has put together a short instructional video on how to assemble Lite Hubs into a wheel. (They do not show the gluing step!)
The machined brass collar allows you to tighten the setscrew securely onto the motor shaft. Tighten just until the collar starts to become oblong. That's all you need for a secure wheel!
