Plastic gear repair

I wonder if this would work for hard to find VCR gears? Will have to give this a try...

You could also just 3D print them.

@ Cornucopia,

That would be the better option, for sure.

With some modifications (up to point for making form) method is fine but probably better results will be use epoxy compound and steel (fine wire) to reinforce epoxy - long term stability may be better than cyanoacrylate (generally cyanoacrylates are prone to fail in presence of humidity which is itself important for their curing but later make them more fragile and eventually cracking).

@ pandy...

You could probably count on the epoxy/steel repair outlasting the rest of the gear

Well, using fine wire (like these in steel wool) should be OK to reinforce epoxy - alternatively some glass fibers can be used too, epoxy resin is pretty fragile. Shear strength for epoxy is better than cyanoacrylates but still not so big... Reinforcing may significantly improve this.

Too fragile, the prints always break in a short time.

Depends on the size of the gears, The smaller the gear the harder to repair or remake, Anything less than a US nickel coin is a pain.
