I wrote a while ago about some wood burning problems I had with my perfectly aligned (or so I thought) table saw (General Internation 50-185 with WWII blade).
The last posts in the thread (from Jack Novak & Klaatu) suggested that I check the alignment with the blade fully raised and then with the blade lowered. That's what I did. Full up, I get a negligeable difference of
0.001" between the front and back of the blade. However, when I lower the blade to about an inch high, I get a huge difference of 0.03 (yes 0.03, not 0.003) that is about 1/32" !No wonder I get nasty burning. Also, since this squeezes the wood against the fence, I'm afraid It could be dangerous for kickback.
I bought the saw last December, so it is still under warranty (2 years) and I guess this problem qualifies as a "manufacturing defect". I'm gonna try and have it checked / replaced by General International. This should be an interesting test of their consumer service.
Anyways, I just wanted to inform the group of my findings in case it could help someone else strugling with his table saw. This is not something that I saw mentionned in any "table saw alignment" instructions I found. Big thanks to the group and Nova & Klaatu for the help.
