    The good news is the old Bridgeport has a really nice Haas HRT210 rotary table, so no hard work with an indexer. I am more worried about the cutter wearing out during the 115 cuts. Is anyone...

    I couldn’t resist...I reduced the speed to 1% and tried the gear. It lasted 3 turns and all the “repaired” teeth shed at once. I’m now gearing up, so to speak, to cut my own gears from scratch. I...

    Thanks, but I am pretty sure I'll get it figured out.

    The latest issue that came up is that, after re-sealing the rotary table, it's not homing any more. Hopefully I'll get the "bugs" worked out.
