Erratus Animus

First ty to Camp 10 and P. moore for their help in getting started by showing me pics of their grinders. This project was not difficult and was enjoyably. I scrounged all the metal from past projects.
I have been collecting parts for a knife grinder for awhile now and after some encouragement I finally got one designed and done. The goal here is to build my own machine and do it as cheap as possible. I was able to build the machine for just a little under 50 bucks.
The motor was given to me free from a buddy and is a brand new 2hp 1740 rpm leeson with a 7/8ths shaft. I needed a drive wheel 10" in dia but buying one was out of the question so I glued up some 13 ply cabinet grade plywood and had my neighbor turn the wheel true and bore the hole for the shaft with his wood lathe. The idler wheel is a steel castor I bought that has 2 grease alimites so it can be lubed. I used the frame of the castor wheel for a swivel on the work table. This allows the table to be set at the angle I want for my grind. a small vice slides on the work table at the angle you set so all the grinds are smooth and even. That is pretty much it. if you have any questions just ask.
I did profile a knife with it tonight to break her in. with my file setup it took me 3 hrs to profile a blade but this one only took a tad under 30 min.
