Well my Ebay press came today with a set of .357 die and top punch in place. I took it all apart and cleaned it and slipped in the set of .452 die and punch and it is good to go but I must first make the bottom push rod with my little Unimat Lathe. I took the dimensions from the .357 push rod and I would like to ask if the head on another cal is the same thickness. The shaft I got with the press is 2.154 in. long and the head is .193 thick, width will be cut to slide in the base of the die. Shaft is 1/4 in. as dictated by the hole in the ram. Any of you who have any size die. I would appreciate the length and head thickness dimension you have and let me know the cal. that way I can verify my intended plan. thanks in advance. JB
