DonF, wish I had seen your post earlier. Sounds like a super idea! I just bought a 5 foot long by 3" diameter (which turned out to be 3 1/8") plastic rod. I'm thinking it will be necessary to turn the rod down to something smaller than 3".I was replacing at least one plastic roller every year if not two. I had my neighbor turn some rollers out of Dogwood that I soaked in burnt engine oil and add oilite bushings. That was over 15 years. The only one I have had to replace was one that came lose and I backed over it with the deck. Give it a try I think you will be supprized how long they last.
Gum is a good choice. Its stranded grain means its almost impossible to split. Consider using a 5/8 PVC or CPVC tubing as a bushing.My rollers on my PK deck is wood. I need to replace them. I was wondering what kind of wood was used. Dogwood sounds like a good choice...
I do the same. I've got a bucke fullt of old boat trailer rollers:tango_face_wink:I have replaced mine with Boat ramp rollers that are far cheaper, and just as good. A band saw can be used to cut to size. Quick search came up with $11.86 here.
