This is one of the thing I struggle alot with on robots, how to attach a wheel to a round motor shaft, i know that wood is the WORST possible thing for this as it fails quickly, but I have a limited amount of tools in my house, how would one go about making a reliable mounting plate for wheels out of wood or plastic?

admin just recommends jamming it in there.

hot glue

or jam it AND hot glue it
:D
lol
bens and pomprocker are both correct , either way will work

noooooo hot glue that stuff doesn't hold very well. super glue is where it's at.

hot glue holds incredibly well! I've never had a problem yet with the stuff and I use it to secure so many things

I really like using hot glue for some stuff, but I don't think this is the right application. It seems like it would put too much stress on the glue.

The high temp hot glue works pretty good. I wouldn't use the low temp hot glue for attaching wheels. It tends to hold for a while, but once it starts peeling even a little, complete failure of the bond is not far off. That is, unless you are gluing to rather porous or rough surfaces.

you have your wooden disk, and your metal axle. I would try cutting a rectangle in the sides of the disk, not all the way through, and put a pin through the axle to hold the wheel on. you can do it on the inside too. it will look cool, and getting the second pin in will be a bit of a challenge, but it is guaranteed not to come out.
For the inner pin, use a small diameter steel bar, and for the outer pin, use some ultra stiff steel wire about the same diameter as the inner pin. bend the hell out of the wire, and it should spring back, into the gap you have. you can put tons of torque on this mechanism without it failing, and unlike glue, it cannot come apart if done correctly.
If you want extra reassurance, glue the pin into the rectangular slot. then you have the best of both worlds.
