Yes, "WE" have thought about that option already, but two of us doing the exact same build and needing to buy two more of the HF style rollers plus 2 times the shipping just seems to be a little bit of over kill. I already have the steel plates for the sides, so that is just a matter of boring a hole in the plate and then using my band saw to open the throats to match the existing units we have. Buying the second pair of bead rollers only duplicates the number and styles of the sets of dies we already own.... redundant I guess but not really needed. I admit that I was just being cheap in trying to buy 2 additional gears and go from there
but I had nothing to loose in asking
