Does anyone have one of these Acorn Tools' Grinders that mount onto a Myford ML7/Super 7 topslide by means of the Acorn "Grinder Adaptor Bracket"? I have the Adaptor Bracket and the instructions as attached (mysteriously printed on dark blue paper) but I am missing "replacement support screw" which I think replaces the toolpost bolt/spigot although the instructions to me are not absolutely clear. Does anyone know if this is what the instructions mean (they do not instruct anywhere definitively to remove the toolpost bolt/spigot)? Is this all I need and if so could someone give a photo/specs please so that I can make one up? The instructions labelled "ACORNTOOLS" NO. 450 TOOLPOST GRINDER are attached. Thanks,

Thanks, Adam

Norman thanks for that – I don't know much about photoshop, but that is certainly easier to read now! Adam

Thanks Bazyle. If it is just a replacement shorter bolt with the same flange (existing bolt too high and threaded part finishes too high for adaptor plate), looking again at it, there is a simple solution that accommodates the fact that also the Adaptor's hole is wider than the existing bolt. The bolt is actually not really required to be shorter, so I will just make up a collared bush with internal diameter to match the bolt and external to match the Adaptor with a height that reaches the existing thread. Part of my confusion over how to mount it was that I mistakenly assumed that the grinding wheel will come at the workpiece from the rear when actually it seems intended to come at the work piece from the front of the lathe as with a cutting tool (not great as the motor gets in the way of visibility). Anyway thanks for pushing my feeble brain in the right direction! Adam. I will put a photo in my album when finished

There is a nice little debris trough that slides out under the grinding wheel as you can see – of course debris powder goes everywhere except for in that little trough!
