    As I see it, the toroidal cylinder segments can be made fairly simply, with just an offset boring bar with a projecting cutting element (or two, three, whatever, as long as they're relatively narrow...

    Also decide whether to go COD for this guy. Offer a small discount to sweeten it if need be, but it sounds like he'd happily screw you over if he gets the chance.

    If you have the option, leave a little material on all the surfaces but the bore (sized for broaching), cut the splines, then somehow put a mating male spline "mimic" accurately trued in a lathe,...

    Nah, by then they'll just take a picture and have their Insta3D™ printer make one. It'll use totally organic-based feedstock, and decompose to air and compost after use, so it doesn't take up extra...

    Good that you're making some progress. If you get a chance, a couple pics of the setup and dresser on the thread would be great.

    Given the OP's lack of experience and equipment, I'd think a single-edge flycutter would be a poor choice for cutting this hole. Even a good drill press doesn't have the spindle/column stiffness...

    Wow, now that's dedication to craft and family. I'd be out getting as much excitement as I could handle (which in that situation, might not be much).

    I'm interested in A2 rod and plate, 7/8" rod would be great, along with 1" and larger. 1/2" and larger plate too.

    Check out the Carpenter website, see if they have any data. At half cobalt, I'd guess on the lower SFM side with good carbide. You may want to check out cobalt toxicity to decide whether your dust...

    Sure, why not. If you do this sort of work again you may want to find a "downcut" tool to help with pullout risk, but usually PCD tools are low (or no) helix and don't create a lot of delam.

    With a PCD tool that's sharp, and with a matrix material that's not gummy (and prone to buildup on the tool edges) run fast - likely your machine can't go faster than any limit. For FPT, try .004"...

    I've done a fair bit of Mg machining, but am always looking for more tips on it. I stumbled across a site that seems to have a number of good pages on it, so I thought I'd share a few:
