    Default A gear cutter grinding jig for tool and cutter grinder.

    SAM_0617.jpgAnd a big hello from this old bloke. Hope you all stay well.
    Sorry the pic isn't better, can't fit my fat guts past all the stored treasures. I took the pic to show a gear cutter grinding attachment off a Cinci No 2 old version. I posted in on another forum in answer to a story on involute gear cutter grinding. The two thumb screws on the pivot beam allow the cutter to be fed in a rotating manner to keep the radial rake constant when grinding. Saw blades can also be ground with it and the pivot arm angled up off the centre body that pivots in the trunion base. Old engineers were of the genius class.

    Hi Steamloco1954, Guys,

    I've seen one of those before, I can't remember where, but do remember playing with it, trying to figure out what it did, but I never knew what it was or for until just now !

    Thanks for the explanation.
    Best Regards:
    Baron J.
