CMS (TS75 insert) fence not square to table surface.

[cliffp]

I recently took delivery of a TS75 CMS insert, mounted the mitre gauge and fence to the table and found that the fence (I had mounted it in the tall orientation) was not square to the table surface all along its length. If you place an engineers square between the table top and fence at one end it is spot on, but at the other end there is a gap of between 1-2mm at the bottom of the fence. According to Festool UK, there are no user adjustments (I certainly couldn't identify any either). Has anyone else had any similar issues? (or would like to offer any insights).

If the fence is similar to that on the router module insert, there are grub screws in the fence which permit you to increase or decrease its angle relative to the table, and to correct the split fence if it is not coplanar.

I described the process in a little video here. Start watching at 2.10.

Cliff is referring to the Angle Stop I believe?

I've put an engineer's square against mine Cliff and there is a tiny amount of daylight (i.e. not perfect 90 degrees) but certainly not even close to 1mm let alone 2mm, and it is the same at each end and all along its length. (NB - it looks more than it actually is in the photo)

Have you tried the Angle Stop from your MFT to see whether that has the same issue?

Apologies I read the first post too fast and missed that he was referring to the mitre gauge fence. I thought he was referring to the main fence.

I did the same test with my fence for the CMS and mine is definitely out as well. I'd say it's out about 1mm

Richard, Garry's correct I am referring to the Angle stop (it would probably help if I used the correct terminology!)

There is (I think) more daylight on mine than you show in your photo Garry. I measured the gap at 0.7mm (not as bad as I had thought though). I checked the MFT/3 fence and it is much more consistent along its length and the gap is 0.4mm (still looks bad).  I am more concerned about the variation in angle along the stop because if I set up the sliding table to cut square, using a large thin square (I have been using a 24" framing square) then cut a 20mm thick panel, the bottom of the panel will not register against the stop at one end but will at the other (where the stop is square to the table).

I know this is an old thread but ever come up with a "better way" or fix?  I was thinking UHMW tape along the bottom or a sacrificial fence to bring it up and plumb.
