- A previous reply suggested consulting Duginske's 'Band Saw Handbook' - a
- suggestion with which I heartily concur.

- Some specific tips on tuning up the 3-wheeler: First, make sure the rip
- fence is parallel to the miter slot - be sure the table bar is seated fully,
- then shim the fence into parallelism. Second, ensure that the guide
- assemblies are holding the blade parallel to the fence. Each assembly is held
- by a bolt; if they are twisted they will cause the saw to skew. Use a
- wide blade for testing this (I find that I can use an 80" long 1/2" wide blade
- with no ill effects). Third, invest in a set of Cool Blocks - they really
- do make a difference. Fourth, block up the lower guide assembly. As it comes
- from the factory, the gap between the table and the lower assembly is much
- too large. Use a longer bolt and some washers to narrow the gap. Caveat:
- raising the assembly too much may cause problems when you tilt the table. If
- you rarely tilt the table, however, raise the assembly as much as possible -
- this provides better support for the blade. Fifth, use good quality _sharp_
- blades and a slow feed rate (especially when resawing). Blade deflection
- (twisting or bowing) is often a sign that you are overloading the blade's
- cutting capacity.
