I recently installed an Incra TS LS fence with the 72″ rails and legs on my Griz 1023 TS. For the life of me I can’t get the runout on the fence less than .004″, and after I move the fence to a new position, the runout becomes .01″ which is not good at all. Anyone have any idea how to fix this? I’ve followed the instructions in the Incra book twice trying to get this working, and written to Incra with no response.

.004" sounds good enough to me. I think this is well within the normal tolerances for aluminum extrusions. Should certainly be close enough for most all woodworking projects.

I would be pissed if I were you. I don't think the issue is '0.004" should be good enough', but expectation should be as product was advertised. Specs state accuaracy of .001" or .002". However, your runout sounds like it is due to table saw table having the run out problem. Sounds like the rails need to be shimmed, when attached to table, assuring rails are parallel to each other. I would guess the table saw's front edge is not parallel to its rear edge. Since the rails are attached to these edges, might not this be the problem?
Wish you alot of luck.
Had a similar problem myself. My saw was not dead level on the floor and it caused the runout. I built a sawbase out of steel and plywood, shimmed it on the floor and then leveled the rails to the saw, made sure the front to back spacing was consistent, etc. Now the fence is perfect. It was alot of work but now I never use a tape to check the measurement. I keep two scales on the guide, one for regular cuts the other with my cutoff block attached for miters & panels.
Thanks for the information. This put me on the right track to figure out what was going on. It turns out that the rail in the back of the saw was not parallel with the saw's table. I adjusted the rail and everything works great with about a .001" runout consistenly. Thanks for your help!Scott
