Aligning the fence on a table saw

Oct 27, 2003 7 Replies

I just installed my Forrestor WW II blade. It included an informative pamphlet on alignment for table saws. I read it thoroughly. I was surprised to see that they recommend "opening up" the fence alignment on the back side of the blade .005" to 1/64". The .005" is for an accurate fence. The 1/64" is for a sloppy or worn fence. The idea is to ensure that you don't get the wood in a bind when ripping - the primary cause of burning and a leading cause of kickback (according to Forrestor).



I'd like to hear comments and feedback on this recommendation. It seems reasonable to me. I compare this to Jet's allowable tolerance on blade parallelism (0.0118") and Forrestor's recommendation easily falls in their tolerance.

Interesting point. I wonder if a shim behind the front of a removable fence face would work to allow it to be "toed out" on both sides? Maybe use feeler gauges and insert one equal to double the desired total (length-of-fence) toe-out at the front end, and thinner strips at appropriate spots toward the back to keep the face from bowing.

I set mine dead on if I can. If you have it open .005 on one side of the fence, it's closed .005 when you move the fence to the other side of the blade, which is sometimes necessary.

I recently set up my new Shop Fox cabinet saw ( bought locally instead of " Grizzly" to avoid shipping hassles; they delivered it to my awaiting Shop Fox Wheeled base) and the T-Square fence clone " Shop Fox Classic" fence describes the same setup; slightly open back side of the fence to eliminate binding and burn. I have not checked it for deviation yet, but with a new Freud Glue Line rip blade, the cuts in plywood and oak are flawless.

After repeated attempts of getting my Vega utility fence just perfect, I shimmed it at the locking head with three layers or blue painters tape on one side to cause the end of the fence to be just -.002 from the front of the fence.

It was easier than messing with the bolts one more time.

I've since seen in books that one should cut a straight board and jam it into the miter slot and use a feeler guage on the far end to adjust it for parallelism.

I prefer as close to parallel as possible... BTY, is Forrestor a new brand of blade?

I misspelled it. Its Forrest, as in Jim Forrest, the president of the company.
