The "humpback" machine pictured in post#36 above is one of the two types I obtained years ago. The humpback I have will roll a stogie-sized smoke by adjusting the length of the belt. I acomplished that by moving the fastening points of the rods that go through the sleeves in each end of the rubberized belt. Instead of drilling a bunch of holes and potentially weakening the frame, though, I'd check out some kind of fine-tuned adjustment to accommodate any diameter boolit desired. The length of the belt could be adjusted by rolling up one end like a window blind, rolling up the belt would shorten its length for paper patching .277 boolits, unrolling some of the belt to paper patch much larger .458 boolits. The mechanism for rolling up the belting could be done pretty easily by replacing one of the rods with a length of 1/16" diameter steel welding rod wire bent triple like a hair pin with an extra leg so it will have a pin sticking out each end to go through the existing holes in the rolling machine frame. I need to dig out my rolling machine and try it.
