Topic tags/keywords: incra fence sliding table saw

So i have an older (1980s) martin sliding table saw. When i got it the fence, and crosscut fence were no good..bent, beat up u name it. I have since replaced the standard rip fence with the unifence, and have an osbourne miter gauge affixed to the slider portion of the saw.

My question is this i much prefer to do all my cutting using the slider rips included which is diffucult/time consuming measuring and getting the board all lined up just right. I am thinking about getting an incra fence and mounting that on the slider side of the saw, this way i can butt my straight edge of the board against that, clamp it down, and cut.

Obviously the rails the fence rides on cannot extend all the way to the blade because the slider is in the way. are these absolutely necessary to keep the fence rigid? i could use them as intended for any rips larger than say 15 inches, but any less where the fence would be sitting up on the slider the fence would be off those rails…problem?

It looks to me like the fence is essentially a longer version of what is on their router table fences (which would work for what i am thinking of doing….. its just not long enough.

Thoughts? better way of doing what i am trying to do?

Anyone using the slider for rip cutting? Fence to left of blade? Definitely seems safer to clamp the workpiece down and against a fence on the slider.

I wish I could help here, being an Incra lover. I’ve been saying I would eventually upgrade my older Unisaw to a Sawstop one of these days and using my TSLS fence with it. But I’ve also been intrigued by the possibility of a slider. The major con with that is the inability to use the Incra fence with such a saw. If somebody could figure that one out, I’d likely be all over it.

I am not familiar with the martin, but have used altendorfs for years. What is the length of stroke on your slider, can it be used to staight line?
We did ripping of hardwood all of the time to the right of the blade. When we had lots of rips to make, the saws were set up with a power feed. We have 12’ sliders so using a wedge on the slider side to straight line then while the slider is in the forward position, set the board over and rip on the right side of blade. A power feeder does make this operation alot safer.
I don’t think I would care for a fence on the left. It seems like it defeats the idea of the slider. A power feeder might be a good investment for you.
best wishes

The stroke is 8 feet, i definitely use it to straight line. As for the fence on the left side, i was thinking of making it able to mount on the extension table with the rails on either side of it, setting the rip fence, then clamping the piece down and using the slider to make the cut.

Power feeder is an option, but it is really more than i need at this point. rarely do i have that many rips to make where it would be worth it. Most of my work is a few rips mixed in mostly crosscuts though.

Cosmic…u have the tsls fence, if the actual fence part were not attached to the front and back rails…just to the telescoping part (as their router fence is) would the fence have movement and deflection in it causing it to be inaccurate?

Also cosmic you could absolutely use that fence to the right of the blade.

This guy did something like that:

The Incra is super-rigid when it is locked. Deflection
is minimal.

Yes, Loren thats pretty much what i was thinking, only using the fence attached to that positioner instead of using the flip stop on one end.

It seems like setting 2 different scales for the rip is just asking for a taper…

Have your say...
