    BTDT is Been There, Done That.

    The arbor is surely removable, I would just make some new ones with a nut. These are a couple from my toolpost grinder.

    I would see whether that spindle extension is removable. Pushing the stones up the taper is a sure way to make mini grenades.

    I guess been there done that, a bit cryptic. I was going to respond WKOGIIAHITESM (what kind of grinder is it and how is the existing stone mounted, spelled out for those not hip enough )

    You need a washer between the back of the stone and the spindle extension.
    What is BTDT? Some partisan code?

    It would be nice to see some more details, like the other end of the shaft and the name plate on the grinder.

    Are you certain that is not a removable arbor? In some cases the entire length may be removable and replaceable.

    it also may be a replaceable quill assembly, in which case you do not have the one for straight shaft / normal wheels.

    You might make a tapered ID adapter to fit, with the OD to suit your wheel. The taper might turn out to be something do-able, like same as a taper pin, for which there are reamers.

  • Mounting grinding wheels/stones to a taper shafted tool post grinder

    I have a small tool post grinder with a tapered shaft for ID grinding. How does one properly mount a grinding stone. If a stone slips, it grinds into the tapered spindle, BTDT. Are there special tapered ID stones? Could I make an aluminum tapered bore sleeve and then bond the sleeve into a larger ID stone? The TPG has a second spindle asm for external grinding where the stone/blotter is pushed against a flange and a nut/washer on the opposite side of the stone/blotter.
