Does anyone make a female swage for entry pipes? I've made several mandrels. What I'm really in need of is a swage block into which I can hammer steel to make the tail of entry pipes. As it stands now, it takes me forever to make an iron entry pipe... and I end up averaging 3 before I get 1 that is half way decent. I form the pipe portion, slip it onto a mandrel, but have a lot of problems with distortion when trying to form the tail. I heat the steel while forming, but something that thin doesn't hold the heat well enough. By the time I get everything straightened out, some of them end up cracking.
