grinder/buffer setup

Here are some pics of my new grinding setup. It is not finished yet, but it is far enough along that I can show you some pics.

Your ingenuity never ceases to amaze me, Charlie. I can't wait to see finished product. Since the contact wheels are sitting in a tray, are you going to use some sort of water bath to cool the wheels?

Thanks for sharing!!

Nice Charlie, looks like a sweet setup for hollow grinding with precision
I know other people are going to have the question... so I thought I'd go ahead and ask....

what are you using for your contact and drive wheels (looks like pulleys or big casters for the contacts)

Very ingenious! Due use extreme caution when using that at least for the forst 100 times. Not joking! Good luck with it and I am interested in reading your follow up posts. :) :gl:

Yes I plan on using coolant.

The wheels that are over 3" are modified caster wheels. (trued, cut down in width, bored for bearings and balanced) The wheels that are 3 and under are made from scratch out of aluminum. I have wheels from .5" to 8"

I'm green with jealousy. Nice, real nice set-up!

That's really cool stuff! A most inventive use of cross slides for tension/tracking and square stock for support of the motors. I envy your ability with the machinist side of this, using castor wheels really saved you some money and also gave you some strong, lightweight wheels.
I like your work Charlie, I really do.:tu

That has the look of a regular production shop in the works. Ingenious Charlie.

No plans, it is just a holder for the wheel and a cross-slide vise for the tension and tracking. It could be done any number of ways.

The grinders and buffer work well. I am now trying to figure out a simple way to contain the coolant as it comes off of the belts.

I am also trying to figure out the best way to build an adjustable platform/rest to go between/under the two wheels.

I am really happy with the results so far.

Great work Charlie! Just when i had pushed aside grinding razors, this pops up.

Outstanding!

So, does it track just by keeping the wheels co-planar? Will this setup let you run the belt so it hangs over one side or the other?

Thanks

You can adjust the tracking one way or the other. The drive wheels are crowned in the middle, the belt always tries to go to the top of the crown. This allows you to make the belt track where you want it.

Sorry to revive and old thread. But its better than starting a new one.. :)

In the first photo, is that a standard Bench mandrel that you machined a new center rod that is longer? Or can you buy one that long?

Also what is the one with the red motors used for? It looks like it woukd send things flying out like a baseball pitching machine... I assume it wasnt finished at the time of the original post.. How about an update?

The first photo is two pillow blocks/bearings with a piece of 5/8s drill rod being used for the shaft. There are tapered adapters on either end of the drill rod.

The red motor thing is my two wheel grinder that I made. It was better in theory than in use, I still have it but do not use it very often.
