    They seem normally to be about 0.4" thick at bottom, about 10mm. I would have to cut one down to 4mm or so for a parting tool, is that going to be too little thickness? It's not just cutting...

    What is the clearance from compound to the centerline of the spindle? I've got about 7/8" as mentioned. Not much, might be different with the 9"?

    Ah... well, I don't issue threats. If you see me holding a weapon, it is in use, otherwise you don't see it.

    The QCTP has been a recurring project idea for me over at least 12 years. It just has never been quite high enough on the list to get me to either buy or make one. I even have a design for one...

    With an ohmmeter it is a reasonably simple job to determine which terminals are connected to which others in the two "on" conditions.

    That determines the wiring.

    Can you make that test?

    What on earth would have suggested to you that such a thing was a concern of mine?

    But I DO have insert cutoff tooling of that size shank..... the shank is that DEEP, for rigidity, but not that...

    Just remember that a WW2 aircraft might only mount 4 light caliber MGs. So there are some limits... payload, range, speed, that sort of detail.

    But a gun is clearly not the ideal weapon...

    Optimist.....

    Ammo weighs quite a bit..... actual guns also.

    Takes a fair sized drone to carry much ammo, although a gun could be lightened up enough to probably be carried by a fairly...

    You seem to be special..... I have not seen any such, and it sees that only one other has had the issue.

    That suggests that it is your computer, and not the site.

    Yes, I know that.... although to use a cutoff tool, THAT toolholder would need to be thinner on the bottom, about 0.187", which would then just barely clear the top of the compound.... cutoff...

    Actually, not so much.. There is a very tight requirement on where the cutter can be. The edge of the cutter has to end up on center, so the position of the tool is fixed.

    The toolholder has to...

    A 4 lead motor MAY BE reversible, it should be if the motor is 120V only, it is not if the motor is 120/240V

    Yes it is, and that is the bulk of your problem. That part needs fixed, and it should not be hard to do. Pulleys are plain turning. You have a little more to do because you will have sintered...

    If he starts at 250 rpm, and uses a pulley ratio of 1.4, he should get 250, 350, 490, 686, 960, and 1350. Back gear at a ratio of 6:1 would then give 41, 58, 81, 114, 160, and 225 rpm. That...

    I thought of making a toolpost, but as they are available cheaply, and no such project will make the 0.912 distance change at all, there is little point to the effort.

    For most , shims.

    That sort of gives me a mental picture of a stack of odd bits that add up to the height, precariously piled up as you try to put in the tool without knocking any of them out of...

    Yeah, if I found one cheap it would be OK.

    The extra overhang is a CHOICE, to use the other side of the toolpost. The RH side does not have gaps or overhang. It is not inherent in the design. just a goof by the P.O. but in the event,...
