Ideally is a MT3 ID & a precision ground OD to hold onto, but since that isn’t the case your live center could possibly have a threaded cap on the end. Any way to grip on the cap & spin the MT3 shank off? Might be difficult since could have been glued when built. If that works it could help...

Contact a plating shop that’s familiar with plating aluminum

Hi Brian, Sure glad to see you at it again. I see these parts would make your list of parts you can make on your bench top cnc mill if that project is still being kicked around. The picture I sent 3 of the angled brass parts are connecting rods for a J. Ridder Euro 50 micro stirling engine I’m...

Don’t know if you are aware of a spin off from Taig called Micro Proto (microproto.com). They have some pretty good deals besides having some slightly advanced machines for sale as well. Easy to deal with and should be able to help you with international shipping. Good luck. Regards, George

Brian, If it wouldn’t be too much of a problem could you email me this drawing in a .dxf file. I’ll make a prototype in a different material just to verify the cam portion configuration. Regards, George

Hi Brian, I have a full 4 axis Taig with Deskcnc software with servos that can easily run a .dxf file as you mentioned. I’d be willing to work with you to narrow down a few possible stumbling blocks. If you can PM me we could work something out without boring the group. Thanks, George

Has anyone made a ceramic mold for aluminum? Looking for a good surface finish out of the mold.

Do a Dura Bar search. Good stuff & consistent in machinability.

Some of the thread tool mfg's. have that info on their websites, Vardex, Kennametal, etc. The multi-thread thread mills usually move 1 pitch in "Z" if the thread length is the same as the tool. If you get a thread mill program with your pitch, hole diameter, etc. I think all you have to do is...

Use these if part won't sit flat on table from #0 to #6 & M1.6 to M3.5.

$425?? Don't know what that means w/o trying it out. They are great machines if taken care of or rebuilt properly. The horizontal portion of the mill takes 5c collets & the B/P M head takes either B&S #7 or a another collet that I cannot remember off hand but the max. end mill is 1/2". Break it...

Andy is "top notch", good quality castings, excellent dwg's. & instructions. Once built it's a very good quality piece of equipment. Had a problem with a part that I machined too deep & it cracked Andy replaced it w/o any problem.

This is what I use & make. Real sensitive feel.

What is normally done is the ends are annealed (softened) then machined then heat treated. If that's not an option try a negative insert with a tough grade of carbide like a Kennametal KC850 & run @ 50 sfm dry. If your finish changes from shiny to dull your part is case hardened & you broke thru...
