I've used my annealer 4 or 5 times now doing 100 to 250 cases per session. I, too, have thought that it would not be too difficult to fashion an adjustable adapter that could be adjusted for case size (so the annealer would feed only one case at a time) and also adding a "tray" to hold several cases eliminating the need to feed cases individually. Let us know how yours turns out. As far as knocking the torch out of position, etc., I feed my cases while standing up and since I am doing everything from above the annealer, I've not had a problem with bumping the torch once I get it adjusted. I think this is probably more cost effective as far as the cost of the annealer than having a fixed torch head, but I don't know. It does make for easy adjustment if one finds it necessary while annealing.
