MFT/3 Fence "straightness"
« on: November 14, 2016, 11:26 AM »
Hi,

I've just purchased an MFT/3 with Rail and Angle Stop and was playing around with the calibration. I used a number of excellent YouTube videos to help with this, including Festool's.

Having got some experience I then thought I would try and calibrate the rail and fence to the 20mm grid of holes instead. I thought this might make using the table more flexible and allow faster setup of the fence without needing a square as I could just put some Parf dogs or similar in a row and align to that. However, in doing this I noticed that the Angle stop Fence is not quite true in that the fence was not equally snug against all Parf dogs (I was using 4 - some much looser and some much tighter). I then verified the fence with a Veritatas 24" straight edge against a light and sure enough at various points, along it's length, I could see plenty of valley's, allbeit very slight.

Obviously, by using the Parf Dogs for alignment in this way problems could arise if some Parf dogs get aligned to a "valley" and some to a crest.  In normal use a length of wood would ride the crests and as long as those are coplanar all should be good and the valleys, if only slight should not matter. 

Just wondering if others have had any issues with the MFT/3 Fence or whether it is most likely within tolerance and using the Parf dogs is just not a good alignment mechanism for the reasons stated?

Thanks, Mark
