Well things are still moving along. I will hopefully have the lathe fully rebuilt in another three months or so.
I worked on the Wonder grinder a bit last week. I finally poured the concrete "pad" for it, and then mounted it up on the caster wheels I had laying around. The only thing left to do is shim up the left side. I love this grinder. I can stand in front of it, with my belt buckle exactly at the table height. Rest a foot on the concrete pad, and have my knee nestled up into that gentl curve you can see under the table top. I can't wait to see how well it grinds little folding blades.
Here is the pad with my 12" boot for reference. Its almost square in size.
I will keep you posted if I get more done in a respectable time frame.

Ron:
I have the same drill press as you:
I also have an old Logan Lathe:
Sorry, mine aren't pretty, and the shop is a mess (as usual).

Good looking garage man. That Buffalo press is quite a machine there, Mine is the base model I think. 
I just put together all the replacement bearrings for it awhile back. I have some runout issues to fix on it before I can put it to good use.

Well I had a busy weekend in the garage. I feel good about what I got done, but it never seems like enough. I am eager to get it all done.
The grinder I purchased is 3 phase. When I realized it was a 1hp 3 phase motor, and that it matched my mill motor. I realized I can run both the grinder and the mill from the same VFD. This needs to be mounted in a Hoffman box and service cables run from it.
This is the motor. The carpenter I purchased this from said the motor to the grinder was burned out. So I hadn't really tried very hard to get the grinder done yet.
When I noted this old knife edge switch, and the carbon arc'ing burns on two of the switch contacts I decided to check out this "burned" motor.
So with the switch out of the motor service box, I used my multi-meter to examine the contacts. This one doesn't look good at all.
This one is done for, and this switch is most definitely bad.
So with the switch as the problem, time to check if it killed the motor. This nine lead motor is wired for high voltage right now, but I can still check the windings. I am measuring the resistance across all three windings. This will tell me if the winding is complete, shorted turn to turn, and I also checked for shorts to ground (which is not photographed).
I decided after reading another thread about quench tanks, that I would try my own idea and use an out of date SCUBA tank. An experiment in action I guess. The tank is about 15 years out of hydro.

Yep, don't trust a carpenter who says a motor is burned out... especially if there is a switch in the equation. Nice work. Love the Teco VFD.
