I started ripping 8 foot WRC boards into strips with my new table saw and had some problems. I set the fence to cut 1/4 inch strips, using a high quality, 10 inch, 60 tooth blade. The test pieces cut a shorter pine board well, but when I started cutting the 8 foot boards I found that thickness of the strips varied. Both ends of the strips were ok, a 1/4 inch thick, but the middle four or five feet were thinner, measuring 3/16 or 7/32. Initially, I found that the anti-kickback paw on the blade guard assembly was slipping between the fence and the stock, causing the board to be pushed out from the fence. I removed the blade guard assembly, but that did not entirely fix the problem. I think the problem is mostly due to operater error as this was my first time using a table saw. I had a hard time keeping the stock seated against the fence. What is the acceptable tolerance for strip thickness? Should the strips be cut thicker, like 9/32, to allow for planing smooth? Also, some strips have burn marks from the blade. Will that sand off, should it be planed, or are those strips unusable? The good news is that I now have enough material to build about 50 cedar strip birdhouses.
