I'm considering either completely or partially replacing the 'fins' on my ancient Promark 310 infeed roller. I would cut/weld these myself, assuming it's not anything exotic - and it sure doesn't look like more than mild steel, which kinda makes sense also since it's not supposed to contact anything but greenwaste. One of the fins got so thin from rust and a life of abuse that it's warped and semi-detached; all of them are deeply pitted and probably worn low.
So there's one question: how tall were these fins when new? 3/4"? 1"?
The real reason I want to do this is that I often have to manually assist the feeder to get slightly-wide crotches or bulky stuff to feed; without my shoving stuff into the infeed chute, the feeder will often just keep scraping over the branch surface while I'm ready & waiting with the next offcut. I often think it would be better for the fins to have teeth, or a sharp edge to bite better into the feedstock. Did these originally have a 'sharp' profile that I just can't see anymore?
Thanks - Dave
