To get the stock flat I use a chunk of "C" channel that I had surfaced planed at a machine shop. I use a belt ( about 120 grit) that I cut and clamp to the steel. You can really get a stock end flat by pushing one end forward and then turn the stock sround and push the other end getting the bottom of your had as close to the sand paper as possible while pushing the stock.

Works for me.
