- Bill, although I have no experience with your model of bandsaw your
- bowing problem is a pretty universal one. It is usually related
- to blade tension. Insufficient tension will allow the blade to bow
- or will give you harmonic flutter in the cut. The other problem may be
- the blade, you didn't mention the blade thickness or tooth design.
-
- I would start by tensioning up the blade considerably and see what
- happens - Steve
-
- Howdy,
- Duginski sez: most hobbyist bandsaws are not capable of tensioning a 3/4"
- or larger blade. The largest I am able to use on my 14" Delta without some
- bowing is 1/2". I do however, achieve good results with that.
-
- As to the blade not cutting in line with the fence, each blade cuts at a
- specific angle for a given setup. Most fences have at least some adjustment
- to compensate for this. The fence on mine did not have enough... I built
- a 6 inch high micro-adjusting fence for use in resawing and ripping.
-
- I highly recommend Duginski's book: "The Bandsaw Handbook" (or something
- close?). Every time I run into a problem with my saw, he has a solution
- described.
-
- Good Luck, and keep making sawdust &-)
