Estimate to build these?

[Guster]

I'll get back with hopefully in a day or so on this. I'm still trying to get the DRO working and some tooling... in the middle of some fence jobs here at the house for the G/F. I may try to get the rear end these are going in apart tonight. I'm hoping I can get the measurements from the OEM gears, the new gears it really doesn't matter about the outer tooth profile, just the inner profile for the splined shaft. I did pick up a rotary table for "rough" cutting, it has some run out in it, but it'll probably be ok for use cutting circles or something if I cannot adjust the backlash out of it. It's 12 inch.

That is the hard part too. Most decent machinist have indexers and even the basic ability to single point fly-cut a basic gear tooth if they don't have the outlay for the right cutter. However the internal splines require either a specialised broach with a decent press or indexed cutting with a shaper/slotter head on a mill unless a dedicated slotter is at hand. This is why I keep my old shaper running as a custom job like this requires no specialised tooling. Others do it using their lathe by fabricating a means to index and lock the spindle and broaching the part by pushing a tool with the saddle which is also very labour intensive.

I think you need to shop around...I found gears like the ones you show for $130(premium) or $80(economy) Frankland Parts Supply will get you there...I'm not sure if you know this but if you get the right set of gears you can have real low gears with the gears installed one way and then swap the gears to get a real high ratio(highway gears)
