OBM grinder

[weo]

Hello all. I wasn't sure if I should resurrect and old thread so feel free to merge this if appropriate, Stacy.

I've got a mild(?) critique on the design of the tooling arms. The way it is connected to the platen and the wheels puts the arm and welds in the way when grinding from the left side, making it quite difficult (for me anyway) to get even plunge lines on both sides of the knife. I have to hold the blank differently for each side a I've yet to come up with a grip (or train my muscle memory well enough) to be able to do this consistently.

I think I've also mentioned in a previous thread that you can't use a file guide on the tooling arm side, even with a glass platen over the metal one. I suppose it's possible to add more steel to extend the grinding surface further away from the tooling arm and welds.

as always

i have a kmg and i sometimes have the same problem. do you use a tool rest ? normally i use the tool rest mounted to the top of the tooling arm, if its getting in the way usually mounting the tool rest to the bottom of the arm cures it with that extra 1 1/2". it may or may not work on your setup though.

I have their patent and rollers on my grinder and have the same issue trying to use a file jig, a very thick platen may stand off enough to give clearance but I haven't tried to rig something up yet. I also had to shim my rollers out a good bit for them to line up with their platen.
Anyway small gripes, and I'm happy with what I got for the price.

Do you have link to that old thread ? I would like to read that thread to better understand what are you ask here . .. . .
PS. You can simple extend the grinding surface further away if you change bottom wheel with bigger one ?
Wait.......I have picture from mine new grinder ....I do it for different reason but this was I thinking ......
