Gears

I'll see if they will post to uk

Looks like they offer UK Postage

Do you think building up the broken teeth with hard facing rods the getting the teeth recut would work

Pin and/or braze is usually the simplest method. You could file the teeth to shape. You have a master/jig available in the other gear, for profiling.

Good find Ashley. Certainly looks like the same part. For less than £15 delivered too.

My thoughts also, Going to be more expensive to have machined

This was my first attempt at gear cutting a few years ago for my table saw. The plastic one was chewed up.

I used a single point cutter that I made from scrap and a broken tap ground to the correct profile.

What sort of machine do you need to cut gears

 

[Fazerruss]

Lathe to make the blanks then a Milling machine and a rotary table

So every thing I want but don't have

It's not plastic. It's a properly engineered tough resin with published mechanical properties. It's used in full size machines.

Why are your gears wearing so rapidly?

Incorrectly meshed? You have to have the right gap. Too tight or far apart don't give great life expectancy from my experiences.

A gap with the thickness of a sheet of paper is ideal

Why not machine all the teeth off the hubs, make up the gears as ring gears then shrink fit/furnace braze the new gears to the original hubs ? The originals must be some sort of casting to be brittle enough to lose the teeth in the first place, steel gears may well be a better job. Just thoughts.
