ok. this is getting stupid. after struggling with squaring the mft3 i purchased woodpeckers mft layout square. oh and the slop stop. two none festool items that should have been a festool made included item. well the slop stop helps keep the rail from moving side to side. and anyone saying you have to skew the rail. shut the up(pardon my french). that is a useless fix. my other complaint is woodpeckers mft square. i can square to 90 then flip the square to check again and the mft is out. really? who wants to buy my mft3? i need the money for a table saw.
