My uncle owns a machine shop and I usually end up there when coming up with some sort of plan.

My new plan is a super smooth and accurate fence for my table saw.

I am doing this because I already have the stuff and I am guessing it will cost me about 75$ to do.

Anyways I am using Thomson linear ball bearings and case hardened 1" diameter shaft on the front and back of the saw.

One thing I been thinking about was the length of the fence itself. I think the Biesemeyer fence is like 42" long and overhangs over the back of the table.

Why is this? I was planning on making mine only 34" long because my saw is 27" deep.

Since this system I am making is going to be pretty sweet I wanna make sure I do it right and am able to use it on any saw for the rest of my life heh.

Should I make my fence 42" and if so why?

Thanks =)
