thanks for taking the time to respond, and I am sorry for my delay in checking. Unfortunately, I cannot open this file as it shows it "is invalid or corrupted". Can you try again or email them to me? I really would like to see them. I am beginning to start breaking this old disc down. I ordered new wheels and am making a new piece to replace the bent tongue support so I can load this up and move it to a better place to work on it. I may in the future pick your brain on availibility of parts (i.e. new discs, bearings) and the nuances of operation and set-up.
