    When I part off a tube-like part on a VMC I use a slitting saw around the OD, leaving about .005" or less holding by the ID. This makes it easy to clean up by flat sanding and/or deburring tool.

    Aircraft length? Maybe, if you're trying to hold tenths on position and not using a spot drill, but then you should be using a stub pilot anyway. Jobber length? Not a chance. HSS or cobalt with a...

    To phrase that a little more politely, the discussion of hobby grade machines is prohibited by site rules. Also, I've never heard of any usable CAM software for Mac.

    This much is spot on. To use a car analogy, you aren't going to build a car for less than what it costs to buy one and have comparable results; economics of scale weigh heavily. Tesla made it work...

    I filled out his survey, but what I could really use for my small medical device parts would be a Haas CM-1 but with significantly more X and Y, and ideally high pressure TSC.

    Yep. Deflection goes up with I believe the third power of stickout for the same sideload. Any little bit you can shorten that tool or increase its diameter will help, in addition to what's been...

    I 3D print a disk that presses onto the base of the stylus and extends just wider than the probe body. If I make a mistake the disk contacts before the body and triggers the probe.

    The tool setter stylus also gets a little dip worn in the middle, which makes small tools touch off longer than they should. After a while I need to drop small endmills a thou or two to match up,...

    I just use the standard Renishaw tool setter, with the standard touchoff cycle. Works perfectly.

    Sounds like a standard used Y axis lathe would do the job just peachy. You still haven't communicated any reason why not, or why your custom build would do any better.

    So you need a 20-30" lathe, and you can't find one, even used, for less than $250k? You're either not looking or you're not communicating your requirements. You should be able to find a...

    Ok, please spell out your machine's technical requirements. All we know at this point is that you want a live tool lathe with somewhere between 20" and 30" of Z, which is a pretty common commodity...

    I'd expect some backlash on that type of machine; you'll have to cut your parameters down significantly from the manufacturer's recommendations.

    The tilt axis brake on my 2015 TR160Y sometimes won't engage. Tech said it's a bad o-ring, and I'd have to send it in to be serviced. do you have a Haas service center in your area?

    On a Minimill can you roll the coolant tank out like on a VF?

    Do you think it's a safe guess that these would also excel in plastics? I'm running a bunch of ABS, Acetal and Polycarbonate, and especially the Polycarb needs excellent finishes.

    OP never mentioned electronics. Sure sounded like he's talking about mechanical components. He mentioned drawings, prints, or broken parts, not schematics or boards.
