I managed to get it put on by myself with no problems and everything fit well with one exception. The actually riser block didn't sit completely flush with the bottom half of the saw. It still tightened down securely and hasn't shown any rocking yet, but it is something I am going to have to keep an eye on since it rocked quite a bit before tightening the nut down. Other than that all the parts are quality goods and fit on perfectly. The saw is up and running, milling green hardwood logs better than ever even without a motor upgrade.
