TS75 deflection problem

[taharvey]

I am trying to get my TS75 is rip some 2" pine boards. But the if I cut straight vs plunge in the same spot, I'll get a 1/16" difference in cut. After cutting straight, the plunge will cut the rail plastic strip even thinner.

I've adjusted the toe, the blade when stopped seems square and true. I am baffled, but nobody in the shop can get this saw to behave.

Any thoughts?

Sound like the guide rail adjusters are loose. Try to tighten them done tight front and rear and then back off slightly so the saw slides down the rail.
This is my first thought to look at.

I would suggest that you send that saw to Festool USA and have them check it out.  I am basing this on your previous posts going back to 2009 about a TS75 saw with virtually the same issues.  If it is the same saw it is a shame that you are just past the warranty period.

Why don't you call Festool tomorrow.  For your convenience they have their phone number on a label attached to your saw.

You are right, it is the same saw. It has gotten shelved for most of that time, because it just isn't as awesome as seems it should be. It was either needed (and couldn't go back for repair, or forgotten about)

I just went and put a square to the boards, and sure enough the boards that the saw was run straight through are not square - the blade must be deflecting.
Where as the boards that were cut by plunge-plunge-plunge-plunge are square

Since the blade is square on the saw with no slop side to side, and appears fine... I am temped to think that is a flawed design that scaling the TS55 to a big blade version would work (TS75) without deflection. I'm not sure I want put any money into having festool try and fix it, when there is a nothing obviously wrong physically, and yet it has never been satisfactory even right out of the box. 3 or 4 people over the last 3 years have looked at it in the shop and can't see anything wrong with it, and yet it deflects, which ruins the whole concept of the saw.

Take a couple of minutes tomorrow and at least call the service department of Festool.  The guys there are great at listening and diagnosing.  My guess is that they will be able to help.

Sounds like you are leaning on it when you cut straight through.

That is why when you plunge it over and over, it is square, you are pushing straight down.
