This is a grind box that I built about two weeks ago. It has the corner rail on one side and the pipe rail on the other side. For the pipe rail side I used a long fence post, and I found that it gives more slide than anything else that Ive seen. It took about 4 days to build spending about 2 hours each day. Also I had most the materials already so that helped me alot on expenses.
built February 2008
