Well my wife saw me looking at a different bead rollers and noticed me looking at a harbor freight cheapy when we went to get some tarps one day. I really was planning on buying a nice unit from either mittlers and such but funds have been tight lately. My very sweet wife thought she was doing something nice and got me the china made Woodward bead roller. I don't want to break her heart and send it back so I looked up about every beef up build up of the hf and wf roller and I came across a few mentioning replacing the set screws and bolts. I started disassembling it to start adding some strength to it and found some of the set screws on a new unit already had the tips broken off. Those that have done this did y'all just replace those set screws with better screws or drill and tap them to a different size? Also the shafts going through the blocks with the bushings in them have a sloppy fit. What if anything has anybody done with that issue? Any suggestions short of never using it or sending it back would be greatly appreciated.
