I have searched and read a lot of mods on the H.F. bead roller. I like the one on the Dayton gear reduction motor and found one online and have it coming. Instead of beefing up the original 3/8 plate H.F. bead roller by welding on the top and bottom pieces to form a c-shape and then adding square tubing to one side why not have the new shape cut out of thicker plate like 3/4"? The wife works at a welding fab shop so cnc plasma is available. Also have not read anything on increasing the throat depth. The H.F. if you count the dies is about an 18" throat depth. While your modifying why not increase the throat depth? Any suggestions as to how deep you may ever need? I am looking at a throat depth of around 25" counting the dies. And obviously the shafts will need to be longer.
