My pipe beveling machine gearbox is shot.
I have an older pipe beveling machine used for prepping steel pipe ends for welding. The gearbox started making a grinding noise and now it will not turn at all. I did find out manufacturer went out of busines, I've tried looking for replacement gearboxes or repair kits on Amazon and Chinese markets like Alibaba. Some sellers offer generic units but I am not sure about the fitment. Has anyone here repaired a beveling machine or similar pipe tool? Should I try to rebuild the gearbox myself or just buy a whole new machine? I have basic tool repair skills and I am willing to learn. The rest of the machine is in good shape.
