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 Bladeforum.com forum in the classified.
Now all I have to do is make a couple knives.

Last year, I decided I needed to make a couple marking knives. As usual I searched the web and stumbled on a new hobby of knife making. As you know the guys motto on hobbies, is "Every project needs a new tool. " Or every hobby needs a lot of tools.
I have made about a half dozen knives, but was using a small grinder. A kit was offered on the Bladeforum.com classifed and it was off the races. So without any further adieu, here is the Eerf knifegrinder.
