    5.0 out of 5 stars Works with 1" Bearings
    Reviewed in the United States on May 12, 2024
    I built a 20" band saw and purchased 1" bearing and a 1" shaft. Even with freezing the shaft I couldn't get it onto the bearings. So, I purchased this. Since it isn't driving a gear, It's OK that the bearings fit a little loose (nothing a small shim made from a strip of aluminum from a pop couldn't fix). I used a grinder to cut this shaft into two 250mm lengths for the upper and lower bandsaw wheel shafts. The chrome is nice since there is 90% humidity where I live at times and I don't have to worry about it rusting.

    Wood sanding wheel, used this to hold the wheel. Added some ball bearings & hooked up to an old drill that only spins one way. Works great.

    4.0 out of 5 stars Cetme jig bar
    Reviewed in the United States on July 8, 2024
    This bar is the right diameter to bend a cetme flat around and buying it though amazon was the cheapest option. It didn't flex in the press, just worked out great.
