Wait.
Files and hacksaws are my usual tools of choice.
Hmmmm..

Many of the older cars had phenolic gears for the timing chain as manufactured. They were later replaced by steel cast gears. If there is fear of damaging the steel gears then brass or aluminum are good alternatives. Both metals are soft enough to be readily machined at home with careful use of files. Yes it takes a while but if it saves you several $100 it's time well spent. Keep in mind the adjacent gears will wear the softer new gear to match them in use.

Cut my own helical gear with file!
That is radical idea. LOL.

Hey the evaporust worked and I have faith in you. Maybe clamp the old gear on the metal stock and use the grooves to guide a small drill to cut the base of the grooves. Then match up the new gear and scribe the teeth. Then just file to the scribe marks?

I was thinking of Joe myself as I read this.

What about making cast mold them filling with molten brass, cool, file to final shape?

That's the way to do it, brass or easier aluminum.

Wow

Now I am about to become Burt Munro. Cast my own idle gear! LOL

Or maybe I should commission Joe to make one for me.. :hihihi:

Most machine shops should be able to make you one of billet aluminum or brass. Either should last indefinitely. Could check here.

I got a reply from this company!
It will be $800. A bit too steep for me especially now I have NOS phenolic one...

 

[slabghost]

Ouch!! That is pretty steep! For that money I'd make my own.
