The Waterloo 15 that I restored last winter needs a new axle: it is seriously grooved (and leaking) at the oil seal. I had one made for the Supremacy 45, but that cost $240. Thought I might take a whack at making one. The biggest question is: cold rolled round rod or hardened steel? The tractor is less than 250 lbs. The axle is 26.5" long & 1" diameter. It rides in bronze bushings. What say yea all?
