My neighbor gave me his dads grinder about 6 months ago. Cheap Chineese , low quality It almost vibrated off the bench even with a 2x10 x3ft attached to it. That's how I got it from him. So after figuring out the shaft was out 18thou, tried to straighten it. I failed. Tried again and failed. well the third times the charm, finally got the shaft to under 1 thou out.Then I balanced the wheels... they required a lot of dimples drilled in the wheel. Finally got that. For the wobble I used paper shims with some steel washers I had, not the pressed type, but the machined type... I only had one set. Gonna make an aluminum set for the other side, the shims don't work for the pressed type.
But now that I am almost done, it's so smooth that putting a glass down on a table (not a bench) and running it w/o bolting it down, I get no ripples in the water. Smooth... gotta balance my big grinder next.. I am so impressed how much it changed it.
 
Had a great weekend getting plenty of tractor time outside and cleaning out some tools once again . It seems to be a never ending process . I did sell three CA-2 Aloris holders though , not that it picks me up any additional room in the garage , but it's a move forward .
 
Well, this ain't much, but it was all I did in my shop that's complete enough to show around.

I declared my Little Machine Shop engine done, made an oak base for it, and mounted it. So this is kind of a "graduation picture" for the engine. It has graduated from being a shop project and toy to something that sits on the shelf. Then we'll use it to annoy visitors with "wanna see my little engine running?"

I built one of those a while back. If you adjust it right, you can run it on canned air, the stuff you use to blow off a keyboard, by stuffing the straw of the canned air into the plastic hose.
 
Just balanced my 8" grinder too. Wish I had known you could drill the wheels to balance them earlier. I though you had to have hubs for balancing. Not that much work, just rinse and repeat until you are happy that it is not stopping at the same spot.
 
Got the A1000 CarryMaster casters mounted on the frame of my mobile mill base. Think it'll be plenty sturdy!View attachment 261203

I've got those wheels on my mill stand. I just used two with two stationary casters on the back. I found them tedious to re-level after moving the mill. I made some 1/2" blocks to put under the pad feet. When I need to move the mill, I use a small floor jack to raise the mill enough to remove the pads, then lower to the wheels, without having to change the leveling. Once it is in the new place, I replace the pads.

Drill the grinding wheel itself? I would have thought that it would weaken the wheel and could lead to failure. Any picts of how you did yours?

See this video :
around the 30 minute mark he is drilling the wheel. You don't go all the way through, you just dimple it with a masonry bit. Make sure it's sharp so you are not putting to much pressure on it. Worked great. And of course ring it when you are done. I'll get pics tonight.. But I'm not taking the wheels off again. I used my surface plate, 123 blocks, and some L's I had to raise the hub. I also used a hand drill and a piece of cardboard to support the wheel. mine were not for a surface grinder so I did not have a hub mounted.
