Was looking through a PDF of Advanced Machining Handbook from the
30s, look in a retro way. It had an illustration of a toolpost grinder.
Now it makes sense.
But other than 1,000 and up, who has a serviceable model for less (less,
less) than that?

I made an adapter to mount my dremel type tool on the toolpost .
Light duty only , but it works rather well . I had to add a .015 shim
(cut from the bottom of a pie tin ...)around the front bearing of my
dremel tool to tighten things up , but that's all .
Used it to clean up and size a couple of transmission roller bearing
races just the other day . Very likely will be using it soon to do a
finish grind on a couple of laps for the motor ...

Please log in for more thread options I have a little aluminum cased 5" bench grinder that I have been
eyeballing for conversion to a tool post grinder. A hold down plate and
3 bolts to mount it and away you go.

I've used a Dremel for grinding small circular cutters on a lathe with
decent results. The mount is a rectangular aluminum block set upright
with a tongue that fits the toolpost slot and a center-height hole the
diameter of the neck of the Dremel. I think a RotoZip or equivalent
might work, haven't tried it because I found a Dumore #14 cheap. The
problem with a toolpost grinder is keeping *all* grit off the very
exposed lathe ways, dovetails and lead screw.

I saw a thread somewhere where aluminum foil was pressed into use to create
over lapping way covers.
