Looking for info on making laps for homemade dies. I bought some brass adjustable laps from Mold Shop Tools that wear out much faster than the steel I used for straight dies for core swaging .I have info on American Lap dies who use cast iron rather than brass for straight laps . What I want to know about is making laps for bullets with ogives and making your own laps for straight bore work in making my own swage dies for pistol or rifle. It seems the topic arises in the posts by folks making dies for resale but never a picture or additional discussion. Any one care to kick start me on an approach?
Also need info on silicone oxides vs aluminum oxides for polishing said dies.Can find silicone oxide in powder form but no source for alum oxide in less than barrel(large) quantities.Any suggestion there?
