So you use linear bearing just to flip grinder You could use them for something more useful

That's a slick jig!

I like nice build grinders, but also i like to read lot about famous knife makers from around world..............And i notice that most of them use grinders assembled from pieces of steel here and there......
So ............say hello to this guy and his grinder

Hey Natlek. That's a Bader Bii that Buster is using. It was state of the art back in the day. I've had mine for forty plus years. A lot to be said for old school industrial machines with machined cast iron frames and precision turned axles.

It is not just jig. It is 90 % done surface grinder attachment.I m working on dedicated surface belt grinder and that is what i use for magnetic plate .Plan is to grind part by part of steel , not all at once .I think that it will be faster and have better finish on end ...

Here is my belt grinder. It looks rough and crude, but it runs fantastically well and I have very few complaints with it. This has been a constantly evolving tool. It began as a project that coincided with the first COVID lockdowns. Because of that I lost my access to a machine shop so I made the first iteration of the grinder almost entirely with a table saw and a drill press. As the world began to recover and reopen I was able to squeeze a few hours of shop time in here and there and started improving it piece by piece. This is likely the final iteration of it as I'm working on an entirely new chassis at the moment. The highlights of the current iteration include a rock solid tracking setup made from 3/4" aluminum stock, rotating on bearings at the base. The platen is 10" long, ceramic, and water-cooled by a pump connected to the power switch on the VFD, so as soon as I turn on the grinder the platen cooling loop begins to circulate. I just recently came into a 3 hp Baldor Super-E motor so I grabbed a KBAC-29 VFD to run it. I'd previously been using a 1.5 hp motor which was more than sufficient for knife making but left me wanting for a little more power when really hogging steel for other projects.

I have a similar shop - mine is an outbuilding with two big doors on it and you've inspired me to make my grinding station on casters. I'm not sure how often I'd work outside but it looks pretty nice to have that option? Other than making the construction heavy and stable - do you have any other suggestions?

The one feature I absolutely loved about that cart was a series of slots on one end to hold different tool arms (contact wheel, slack belt, work rest, etc.) so that once I rolled the cart outside I had everything I needed on hand. That cart was also on casters that flipped up so the cart was resting on solid feet. It’s a useful feature but I didn’t find myself using it much because the cart ended up so heavy that it didn’t need the extra stability just for grinding.

Much appreciation.

I went with the das tubinator for my first 2x72" grinder (stepped up from 1x30") but thanks to the advice of this forum I went with a VFD and a 3HP motor, better to go bigger than regret not going big enough.
