Mounting Wheels
« on: January 15, 2009, 03:23:37 PM »
Does anyone have experience mounting these neoprene foam wheels to hubs?

I also bought the recommended hubs.  Can this wheel be disassembled and then the hub screwed and nutted to just the inside piece or do I need to drill through the entire wheel?

can't you just superglue the hubs to the wheel centres?

I don't want to go that way.
The hubs are aluminum.  Super glue (cyanoacrylate) does not form a reliable bond with metal.  Even if it did, that would eliminate any possibility of changing the wheels.
Thanks for the idea, though.

The two halves can be pulled apart if need be

Scroll down a bit until you see a pic of the wheel. I just drilled two holes and screwed in my servo hub.

Looks good as a servo mount.  Thanks, admin.

But I actually needed to mount it to a hub for a 6mm flatted shaft from a gearmotor.  Here's how I ended up doing it.  The Lynxmotion hub had a #4-40 threaded hole at the center and a #4-40 screw for bolting it on through the center of the wheel.  The problem is that the wheel hole size is a #8, not a #4.  Tssk, tssk.  Very sloppy, Lynxmotion.  So I bored and threaded the hub for #8-32.  The wheel fit very tightly on the #8-32 screw and was nicely centered.  I used a star washer on the outside and some threadlock to make sure the screw didn't back out.  Bootiful.
