That looks like a fine grinder.

One suggestion ditch that belt you have and get a linked belt from Harbor Frieght. It will run much smoother and with less vibration.
 
Very sweet. I like you interpretation of the 3 wheel grinder. Since you machined the spacers you will likey have excellent tracking. The alignment of the wheels in key. It's interesting on the my kmg that the 10" contact wheel I'd 2" wide the drive wheel and idler 2.25" and 2.5" respectively I believe. This make alignment of the center line a bit time consuming if you mess with drive wheel.

Anyways, grat job. Are you planning a flat platen? If so, maybe use different size contract wheels that would allow a full 180 degree flip to have a slack belt setup. Ed Caffrey and the Grinder in box (GIB) have pretty interesting designs of these modified plattens.

You've done sucha great job with your lathe work, maybe mount the grizzly wheel and clean it up to make it look cleaner. :)

I'm dying to see a picture of it tilted. Any chance you will post one?

Definitely. I want to get my first batch out for heat treat, and I don't have an immediate need for the tilt (I already have a 9" disc for rough profiling), so I figured I'd work the tilt mechanism or stop when my first blades are out for HT. I also need to come up with something for small radius profiling, because a quick-change tooling head and rollers isn't in my budget unfortunately.

I went over to pop's hardware emporium and found a couple of air cylinders and a couple of air springs I was keeping over there, so I am going to be playing with those while I'm waiting on HT.


I definitely plan to redesign the tilt mechanism, now that the grinder probably will be staying on a stand. I've had some medical issues, etc. pop up, and my full shop with stationary tools seems to be farther and farther off every day. I still love the idea of a semi-stationary base with a work surface and storage, but for now that's going to have to go under the "I'd like a late model corvette" category.

I tend to do this a lot on first drafts, I'll try and design something in ten different directions to satisfy all of these variables, and then find out it doesn't satisfy the one variable I end up needing it for.


I did test it with a piece of wood as the stop, and it seems to keep its tracking and everything, so at least I'm good there. It is heavy, when all the way tilted down, but when upright it is pretty well balanced, so it gets easier to tilt the closer you get to the latches. I may just use a simple stop until I redesign the motor mount/tilt into a single bracket.
 
Sorry to bring up an old thread. . .But since I have a 2x72 en route, and I have limited space in my shop, this mobile base greatly interests me.

Now that you have had some time working with it.

What about this base do you like?

What would you change?

Do you feel that gussets would improve its performance?

How hard is it to change the height? Seems like it would be awkward to lift that heavy unit, and reach under to lock it down.

Thanks in advance for your time.
