One of the weakest points of the power hacksaw is the design of the frame. The two (2) bearing carriers must be perfectly aligned or the saw will bind during use. A much better approach:
1) Cut a length of 1/2" black pipe to a length which matches the bend hacksaw frame
2) Ream the ends as needed to get the Oilite bushings to fit
3) Weld the support brackets about 1.5" from each end of the pipe
4) Weld the pipe / support bracket assembly to the frame
5) Install the bushings in the ends of the pipe
This design change eliminates the need to align the bushings and makes the saw operate much smoother.
