My 32″ long Bess-like TS fence bows inward towards the blade about .010″, starting just about at the front of the blade. I know we’re not making rocket parts on the table saw, but I’m wondering is .010 is considered “bad”. THe bow is over about a “14 inch span along the fence. What do you think?
For the record, the fence is adjusted .005″ open at the rear of the blade. per the Forrest Guidelines for Carbon Tip Sawing: http://www.forrestblades.com/Forrest_Saw_Blade_Instructions.pdf
Just Wondering,

If a straight edge rocks on your fence, thats no good. Can you shim it flat?

Yep, I checked it and it rocks. Not much but it rocks. Thanks. straight edge was a good idea- I measured it with a dial indicator. The other side is bowed inward- the whole dam thing is bent in the middle .010... I cant shim it because the bow is outwar, in the middle, not inward.

Keef,
Maybe you could take it to an auto body shop and they could try and straighted it on some of their hydraulic straightening machines. Or you could try and tap it out with a few well placed taps with a hammer and a wood block. Good luck! Danny

Couldn't you shim both ends of the fence out a little to match the bow?

If there is enough meat on the fence, I would flatten the face on my edge sander. If you do not have an edge sander, any machine shop wiff do it for you. I would not go to a body shop, nor would I try some well placed blows to the fence. JL
I wouldn't bang on it either, but you might use a small hydraulic jack as a press, across two blocks, or take it to a machine shop with a press, or make a wood face to the fence, with the wow worked out.

The fence has wood (or maybe plastic) faces, on a steel structure, right? Don't fuss with straightening the steel. Instead, shim between the faces and the steel. Shimming you can do in your workshop, with woodworking tools. Messing around with steel takes a whole different set of tools and machines.
You might also take the opportunity to replace the craplastic faces with nice real hardwood like maple.
Keef,
How old is the fence and have you contacted the manufacturer about it no being true?
