I cut most wood without much problems, but
I was cutting a lump of tree about 10" dia against a guide on the right
of the blade and as I pushed the wood in the blade moved left the
further I went in and came back slightly at the end of cut.The resultant
cut was not flat but curved over the 12" length.
Many possible reasons
1. The blade may not be sharp.
2. You may not be using the proper blade, you want fewer teeth per
inch. You may not be using a wide enough blade to help absorb and
3. Feed rate may be too fast.
4. The blade may be heating up in the cut and expanding thus lowering
the tension on the blade and causing a tracking problem.
5. Your fence/guide may not be set to account for the natural drift
unique to that particular blade.
6. While your saw may have the clearances to cut that deep of a cut the
saw in general may not be up to the task of cutting that much wood with
Also, did you remove the bark? I find the bark ruins blades pretty fast.
I use a draw knife to remove the bark.
Did you have a sled?
I stopped using a full sled, and now use a sheet of ply I find it give
me nice support on both sides of the blade, avoids some other issues I
was having. YMMV...
