I was ask to post more pic's of my grinder awhile, so here ya go.

I made it out of my old Kalamzoo 2 X 72 grinder.

Cool thanks for sharing!

Geo, I cant tell what that grinder looks like. Step back a couple feet and take another group of shots. Is this something we can make? I see a cross vice but what does it do? What is the magnetic chuck mounted to?

I looked at it 2 weeks ago when I was there. There are two cross slides, one adjusts the height of the wheel(Z axis) the other does X and Y (and is the one the mag chuck is mounted on) very cool setup!

I wonder how hard it would be to make something like that would hold a blade and attach to a KMG tooling arm...and then surface grind on the KMG

Thanks, the cross vice on the bottom that has the chuck mounted looks to be a bigger longer travel one. Where do you get those? It looks like a small milling machine table actually. I wonder if I could mount a belt grinder on my milling machine and use the power feed to move the table? Might be something to think about.

Wow that opens up my mind some more. Thats cool Geo!
So is that a milling machine table?

The cross vise on the bottom was from Enco.

They sell just the long travel cross vise? How much?

I got it about 5 years ago, it was around $120. I think

Now thats a good idea. IG your my hero

IG, I'm curious about the Z-travel - because the X-Y-tables are designed to work horizontally (in terms of gravity).

Did you have any problems/considerations with the tracking/play of the Z-travel?

Fellhoelter · May 12, 2008

I'm more curious about the travel along X...

Doesn't only moving .2" per revoultion mess with you?
I picture heat generation being a problem, and dwell marks...

All my experience is with a rock though, never messed around with a belt.

Real nice George , and I can say that even though I don't own one!!! Frank

So far no problems

It is off by .001", but I use the grinder for surfacing off billets of Damascus mostly.

As long as you keep the table moving you do not get any dwell marks. As far as heat there is no problem as long as you use a new belt. I use the 977 belt from Pop's, they are designed for high pressure applications. With a new 977 40 grit belt on it, I can take .005" per pass.
