Very nice work!👍🏻

[@DudleyToolwright]

Thank you! Cheers!

[@jsteifel]

it pulled in because they are deep flutes and you conventional milled. If you climb milled with the locks holding firm but not tight, it may have worked better. The climb would prevent digging in. I wonder if you tried drilling most of the waste away, then doing a final cleanup

[@DudleyToolwright]

I edited out hours of the actual cutting. I tried both directions, when cutting with similar results. The gear lash on this rotary table is completely unacceptable.

The part moved in the vise. I think mist coolant would help regardless of if you’re using hss or carbine.

[@DudleyToolwright]

Interesting advise, thanks. I have always resisted using coolant on every machine other than the surface grinder. I think I need to get over it.

Maybe you should weld all your pieces to the bed !
Drum brake parts have blacksmith tolerances .
Slow up a bit and take a deep breath .
Advice from a old man from down under

[@DudleyToolwright]

I appreciate the advise. Unfortunately, CAT has incredibly tight tolerance requirements for these pads, especially considering that they are stamped metal - and they don't even have any reference surfaces. I am making a fixture for the sub-contractor of a sub-contractor. Crazy.

Very interesting.

Cheers.

This is so useful!

[@DudleyToolwright]

Glad it was helpful!

I imagine that rotary table is going on E-bay after you are doing. 😀

[@DudleyToolwright]

Thanks, Tom. I am thinking of modifying it to be a rotary fixture for the surface grinder.

I always found rotary table work to be sketchy. I'm wondering if it would make more sense to take material off with shallower cuts at 1/2 to full endmill engagement so that only the bottom of the endmill is doing most of the work?

[@DudleyToolwright]

I did try that with equally poor success. I had to edit out a ton of footage. These 4 - 20 minute videos came from more than 6 hours of content. I had to uses significant breaking no matter what I was doing, because of the poor gear meshing of the rotary table, which only cost me a couple hundred dollars. I shouldn't have tried to save so much money.

@@DudleyToolwright Gee, that’s a crazy amount of film editing! I thought I was bad lol. I have an 8” Vertex, don’t know if it’s any better but I remember there not being any backlash. Interesting work projects.
