Nils,
I hope you got some good information from the search that Per provided as well as the post from Tom.
I'm a little confused about how you are using the MFT to rip 2" strips from a 4' 9" board (or is it 3 to 5 meters?). The MFT1080, which is what I assume you have, is 45" long. So I guess you are using the MFT as a support for your work piece, and using a guide rail clamped to the work piece to make the cut. It would be impossible to cut a 4' 9" piece using the MFT fence and guide rail, even if the fence were positioned parallel to the short side of the MFT. There are some threads here on the FOG about ways to rip narrow stock using guide rails and a TS55 or TS75. Per's search should have pointed you to some of those. The main point in many of those threads is the need to provide adequate support under the work piece on both sides of the cut and under the guide rail, making certain the guide rail is flat on the piece being cut.
I'm also confused about your comment saying you "needed to use the MFT fence in the upward position". I am having trouble envisioning what you were doing, and what you expected from the rail in a vertical position. The way the MFT guide rail is attached to the bracket, I cannot see how you would expect the rail to be perpendicular to the table top in the raised or vertical position.
Perhaps you could post some photographs of your setup so we can offer some advice to you on your specific applications?
I hope you will focus on the hard facts yourself, and provide us with some more information about the specifics of what you are doing, so that we can help you.
hi Daviddubya,
most of that search path of Per was known to me already
sure, when ripping 3-5m long planks you have to use rails
only and clamp them to the wood that will be ripped, the
problem is you need perfect support on the left side under
the rail and even then it works only in theory
now, the fence and the rail
not sure if you are using the MFT yourself or not, but the
fence can be applied on the table so it is only 10 mm or so
high or you can rise it 90 degree and the alu profile will
now be approximately 30 mm high
when using it in this high position it is not perpendicular
to the MDF table top
also, when you try to adjust it for square against the
rail its almost certain you'll bend it
why do you want me to have the rail in the upward position?
I am talking about the fence in the upward position when suddenly
you convert my fence to the rail in the vertical position?
then again, the alu profiles along the sides of the MFT are
not perpendicular either
ripping same width or less of solid wood as above but shorter
lengths of 20" to 40" on the Festool bridge always require different
kind of support and jigs and most likely it still won't be
perpendicular and square
my intention is to get a better rail system for my Festool
TS75 circular saw and square and perpendicular cuts
why are some people so upset over the idea of using a
Festool TS75 on EurekaZone rails?
is EurekaZone rails a bad product or are some of Festool
users just afraid of getting a better rails for TS75?
if bad, please tell me what's bad with it, same way
I described the malfunctions of my Festool MFT
