Aveling GND Diff Inner bevel Wheel
 

Hi guy's wondering if anyone has any patterns for an aveling GND tractor (1914)bevel wheel gears and possibly the pinions as well for the diff that we could borrow.
We have found a crack in our inner bevel wheel its been repaired in the past but certainly its days are over now, The crack goes right through the web of the spider and is not worth repairing. just looking at the options open to us......cast is one, complete new set cut another or if anyone has a random spare or can point us in a direction it would be very much appreciated All comments and help welcome


Kind Regards Rob

Have pm'd you .

Rob, PM Snail Trail on here, they have had or are having an additional outer bevel for a GND.

I believe they are using the existing as the pattern as the shrinkage will only effect the outside diameter. My guess is you could use the outer and a turned bit of wood as a pattern as an inner.
