Knife Grinder

The grinder is now complete. Except for a nut with a plastic insert and a graphite pad for the platen, it is ready to go.

Specs are as follows.

2 HP motor with a VFD speed control. Make sure you use a TEFC motor as the metal dust/swarf will foul the motor. I found a stainless steel one on Ebay cheaper than a normal one. The VFD is in a NEMA 4 enclosure. In order to make the motor variable speed you need a three phase motor hooked up to a VFD. The VFD takes single phase 220v to 3 phase 220v.

The motor is 56c frame with feet.

I have two grinding setups. A flat one that tilts and a dedicated 8" wheel. I also have a 2" wheel for the handle.

A tool rest. The grinder is set up to tale the standard 1 1/2" tool post found on a KMG grinder.

The metal frame kit was found on the forum in the classified.

Now all I have to do is make a couple knives.
