Even though my GPR will drive nails, I can pick up the fired patch and it looks as if only one side of the patch is dark, like I always have more material on one side of the ball. I have to run up town tomorrow so I'm gonna go by the fabric store and get some ticking. Now when you measure the thickness, do you pinch the material real tight between the jaws of the caliper? I'm gonna try to get around .010. Well at least with a .535 ball and .010" precut patch she does good. Then I will cut a 2" strip of the ticking and put it in a pot of melted beez and tallow. Then pull it out and hang it up to dry. Does this all sound about right?
