Here are some pictures of my new grinders.  When I built my last grinder, I welded alot of it together.  After many hours of use, it needed to be rebuilt, but that was almost impossible because it was welded.  So I kept the motor from the old grinder and kept it then disassembled the remaining parts.  The picture with both grinders show them setup for 72 inch belts.  The one on the left is the hogging grinder, using the 1 1/2 hp motor at 3450, while the wheel grinder next to it has a 1 hp motor running at 2850.  The third and fourth those these grinders in more detail.  The second picture shows it configured for long belts.  The one pictured is a 120 inch belt.  It will take up to a 168 inch belt, and any of these grinders can take up to a 3 inch wide belt.  The bench they are built on is quite solid, and is higher to reduce neck fatigue.  All I have left to do is clean up the wiring.  The space below the bench will be used for a dust collector / air cleaner.

Here are a few pictures of my old grinder in use.  My grinder uses a 1 1/2 horse motor running at 3450 rpm.  This really takes matieral off fast and throws most of the debri straight down.  Some of it likes to continue around with the belt.  The third picture shows a metal catch at the rear of the grinder.  These pictures also show that I don't have it at the proper grinding height.  My neck is sore after doing a lot of grinding.  I'm in the process of making a new grinding station that is higher.  I'm also adding another grinder that is variable speed for finish work.

Safety is something to keep in mind while grinding.  Some of the grit goes flying all over and stays in the air.  If you don't have any dust collection in your shop, you should.  This first picture shows me ready to grind.  I have my goggles, respirator, hat, and ear plugs.  The goggles are self explanitory.  The respirator prevents inhaling all the dust particles while grinding.  The ear plugs help keep my hearing and keep small, hot pieces of  metal out of my ears.  My goggles have a small gap between them and my forhead, the hat covers that gap.  The second picture shows a still glowing particle ricocheting off of my hat where it would have possibly gone in my eye(s) before.
