Ive seen a hint in a magazine how to turn dowels on a tablesaw and make MT joinery.
I took it one step further, since I put wooden wheels on some of my outdoor furniture(lounges, bbq carts) and I like to use wooden axles, not readily available in the species of wood I use for the outdoor furniture.
I could pay someone with a lathe to turn long blocks into nice round ends for wheels, but I just took a piece of pvc pipe, size is relatively unimportant, the pvc comes in a ton of sizes. For my practice jig, I used what I had laying around.
Cut a piece of scrap to fit inside the pvc, snug fit, tapped in with a rubber mallet, and I can always put a countersunk screw in to hold in place.
Put a scrap of plywood on table, clamped it down, raised the blade a bit, placed the fence at how long I want each end to be.
Then I just made sure my hands where plenty clear of the blade, and just turned the pvc pipe around and around, letting the blade trim off the excess, raised the blade a bit more, did both sides again. Just kept turning the pipe, I got two nice ends that I can drill a one inch hole through the wheels and attach to frame of furniture.
dont have to buy any dowels, which are rather costly, and like I stated, cant find PT dowels, or redwood, red cedar, white oak, etc.....now I just need a piece of 6/4 or 2x4, and stick it into the pvc, then rotate and out comes a perfect axle.(I will sand it perfect when I make one to use)
