Bench grinder stand for multiple grinders?

[Com_VC]

Hey all,

I'm trying to setup my bench grinder properly as at the moment it is on a flimsy stand and it vibrates quite badly. I think the reason it does this is because it is made from 2mm steel angle.

So i'm thinking of making a new stand for it, I have other grinders as well, one is setup with a wire wheel that I use for cleaning up bolts etc and the other I have a buffing wheel on it for polishing.

Now it would be great if I could have something setup with the 3 grinders on there or even provision for 4 if need be. That way they are always there ready to go.

Anyone done something like this before, any ideas?

Thanks

well i would go with some 2"x2" thick square tubing. have four feet. the thing i would strongly suggest. actually i just thought of it reading this. is if you work by yourself then you could mount all four on one large plate. you could have it rotate depending on your shop space. or you could just have one plate with slots if all the grinders are the same bolt (or make adapter plate) so you can slide one on and use some wing nuts to quickly tighten and make a hanger below with the same slots so you can hang them on the stand. but if anything i would get some of those hockey puck style engine mounts. http://www.speedwaymotors.com/Universal-Bolt-Through-Engine-Mount-Cushion-Kit,1199.html
i have them for my hot rod they would definitely absorb the vibrations if you put them on the legs.

To be able to use the buffer, you need to have its wheels off the table. Sounds like you need a triangle shaped table, on a lazy susan, with bolt holes by the tools to drop a bolt down to hold it stopped.

There was a shoemaker in my neighborhood when I was a kid who would re sole our shoes (remember that!). He had a giant cast iron belt driven buffer without a dozen different buffing wheels on in. I would love to get one of those and put different grinding wheels, wire wheels, and buffing wheels on it.

Sounds like a good idea, but I don't think you want the buffing wheel that close to the grinding wheels would you? seems like you might get a lot of grit on them, just my opinion.

Seems like it would be easy to make a cover for the tool. And if you clean up after yourself, or have your mom come in for you...

I use this one from Harbor Freight, it's bolted to the floor and doesn't vibrate. It's cheap enough so you could probably buy a couple of them for grinders or buffing motors. I don't know if they ship to Australia, but if not, there should be something local that's suitable.

The most likely cause of your vibration is out of balance grinding wheels. Do you ever dress them with a wheel dresser? Take the wheels of the grinder and run it, if it still vibrates you have a motor in need of re-balancing.

My take... I vise grip as required but will eventually bolt 'em down.

Thanks for the replies, I took the wheels off the grinder and the vibration went away. It's so bad with the wheels on, if I have something resting on the tool rest I cant keep it still it shakes so much.

Do you think it is the wheels? I still have a feeling it might have something to do with the flimsy stand I have right now. I might try clamping it to a heavy bench I have here and see if it goes away.

I do have a wheel dresser and it didn't make any difference except my wheels are nice and straight now.

Thanks

Mount one grinding wheel, spin it by hand and mark the bottom when it stops. repeat this a few times. If it stops in the same place every time you have found the heavy spot.repeat this procedure with the other wheel. Then mount the wheels with the heavy spots 180 degrees apart. this is probably the best you can do without buying better wheels. Surface grinder have special hubs that allow you to balance the wheels but they are expensive. If you are using a wire wheel you have no hope of not vibrating especially if it comes from China.

I use this method to balance wheels; 3/4 down the page:

I put 4 on a little cart that I had. 2 on each side. It has wheels so that I can easy turn it around to use the 2 less used grinders. It also makes it easy to move around the shop if you need to access for a longer piece.

I like Grinder Bill's clean looking rolling cart and hope to build something similar just for my metal working one day. I just finished a similar (albeit smaller) project yesterday to reduce down the number of individual stands I had in my shop. I posted some pics at the end of this thread. http://www.garagejournal.com/forum/showthread.php?t=100158

Every time I look at those HF stands, they seemed dangerously top-heavy and tippy on that three-legged base. However, you've bolted it to the floor to solve that problem. Not something everyone would want to do, but it works for you.

I made a wall-mounted shelf from a full-thickness 2"x8" plank. The wood absorbs vibrations much better than steel. Having grinders on a fixed shelf does limit access of long and/or odd shaped pieces, but life is tradeoffs.

I tool a 30 inch circle of 1/4 inch plate centered a hole in it for electrical in it ran a 1 inch conduit thru it with at 4x4 weather proof box 4 outlets and set the whole works up on a bench with transfer rollers under the steel for the top to roll on. Set up a stop so system would only roll about 350 degrees and bolted 4 different grinders to it. Put a stop latch system to keep it from moving when I use it. Works great, general grinder, surface grinder, buffer, and wire wheel. Also have a tool grinder mounted next to it on that bench.

I mounted my 4 grinders on steel plates slightly larger than the base, made a mounting bracket, and just slide whichever grinder I need into it. Doesn't take up any more room than the one grinding pedestal.

Hi; I'm back for more abuse...

I built a new stand for the bench grinders/belt sander. Truck rim and length of 8" pipe and features retractable wheels:

The rolling table now has a vice:
