While sawing up the material for the retractable internal tool holder on my 4x6 band saw I noticed how out of square it was cutting. When cutting smaller sections it is not that noticeable but as the stock size increases, it magnifies the error. This is the simply method I used to realign the bearing guides and the saw is again cutting straight. This poor little saw is now 20 years plus and sits in the workshop and gets used and abused with next to no maintenance but is still going strong.
The first couple of photos show the problem
The next photos show how I fixed the saw issue. To try to place a square against a ½” blade to check it is vertical is quite difficult. To overcome this a 6” rule clamped with a small tool makers clamp to the edge of the saw blade gives a good indication on how far the saw is out. With a square placed against the rule, both bearing guides are set until the rule is upright and therefore making the blade square to the base of the saw vice.
The last photo shows the saw once again is cutting square.
Many thanks for taking the time to view
