    If it were me I'd go with a 3 flute Zirconium Nitride coated tool in a shrink fit holder. Corner radius where possible. In some cases a sidelock holder may be better if you can get it in a shorter...

    I use Franks' machine too.

    Option 1: Setup a spare tool before you need it, doesn't matter how slow it cools.
    Option 2: Setup the shrink tools for a job first, then let them cool while setting up...

    Check out the service centers in your area. For example, here in MN Haas support is great, but I keep hearing horror stories in other parts of the country.

    Correct me if I'm wrong, but I don't think a high feed mill is going to care much what holder it's in. Forces are mostly axial with the spindle, and they're very tolerant of runout.

    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,...

    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.

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

    I've got a DI system for machine coolant. We have very hard tap water and I run it straight through the DI system, no problems.
