    Well, start saving up for either a replacement spindle, or do some digging into whether the oil/air is working.

    Maybe some searching this site for other Haas spindle issues will help give you...

    Confirm that the air line that carries drops of oil to the spindle bearings is still functional (no cracks, on its fittings), and that the oil is metering correctly.

    If you've not seen drips of...

    Would be nice to know if this is a one-off, or a production run. I'd take that time for one piece, but making a bunch it would be too costly.

    Back to the original post - I wonder if this is a...

    Thanks for the follow-up. But would you please explain what you mean by "stack cut"? I've used annular cutters on my mag base drill, but I'm not familiar with the stack cut phrase.

    Shouldn't be bad at all, but you'll work it annealed, then get it hardened.

    As to the sharp edge, rough it prior to hardening, then sharpen for use. A soft cut board will be needed, even...

    As to this, I think so. When I was a young Milland (many, nay, all the Moons ago), I went to a Eastec-like show with my pop. One of the exhibits had what looked like a solid steel cylinder, perhaps...

    Gearbox is (likely) a relatively large part, with a large MOI. That can make manipulating onto a locating plug tricky.

    This part is a hand-held (~135mm long) piece, likely just 10 lbs or less...

    I'd talk to the folks who make silicon wafers. This sounds like it's in their wheelhouse.

    Let me expand on that - I think this project would have to be REALLY solid and profitable for you to...

    Or better. I'd be comfortable shooting for half that on a lathe. Give me a proper grinder and I'd halve that again.

    No, that's when the CH is shaved off (at least, done right).

    [Yes, I'm going to hell. I already had the ticket, might as well enjoy the ride]

    Making an arbor a slip-fit on a good bore (which it should be if done correctly) is standard shop-stuff. I'm presuming the OP can do that fairly easily.

    It seems to be the bore and key that (at...

    Stupid questions - why not rough the part, drill a ~14mm starter hole, then finish the bore and key in the WEDM? Then throw it on an arbor, and finish the rest of the geometry. As long as the wire...

    Combat Air Hockey. You think regular hockey players lose teeth? You ain't seen nothing yet...

    If it's the faces that both need to be mirror finish and flatness, it sure sounds like a lapping job...

    Implmex's cautions are very helpful - thanks for that, Imp.

    If the extra wire time isn't an issue, an undersize slot can be cut, verified, then the final size cut after any needed adjustments.

    Well, I'm gonna ask why are you using a "cheapy drill", when it's the smallest part of your cost in the process? For gosh sake, use a quality drill and optimize your process around that!

    I don't understand why you're not making the metal part out of low to medium carbon steel. If you do, no worries about heating it unless it's a leaded steel, then you might vaporize some of the...
