custom tap

My buddy would love a quick change gearbox, but his finances won't allow. Myself, I'm happy with my manual change gear setup. Maybe, in the future, I'll go to a bigger lathe with one, but only if I win the lottery!

I'll be the first to admit I'm still at the "that's good enough" stage. I'm getting better, and my setups and tooling is improving. I made the tap as close to spec as I could get. I made a nut with it to use as a gage for the screw thread I need to make. The screw will mate with the tapped hole made by the tap I made... Whooh, I'm getting dizzy...

It's hard to decide which is more satisfying , building something from a blueprint (drawing) , or from your head . Either way the most important part of the job is doing it , making something from nothing is always worth doing , even if it doesn't work (it's happens ) . The joy is in the work ............

The older 920 Lathes had a norton style quick change gearbox for thread cutting. Speed changes were by belt slipping though. Still, if you cut a lot of threads it's quite an attractive buy if you can still get one. Not many vendors stock them anymore.
