We are in the same process of changing the axel on our
boler, and we ordered an axel from Paul Neumeister in Ontario. He's a great guy that sales
Boler parts as a hoby. He has them made acording to
Boler scantlings, and honstely it does not look to hard to install (4 nuts and bolts..) we choose an axel with
brakes plus bolts and it came down to around 800$ with shipping. Just an other option for you!
