My MFT 3 is on the way. Should be here early next week. I will try the legs and report in. It may be a quality control issue.
I have developed a theory about the infrequent lapses in Festool quality control. It is reminiscent of the early days of Detroit automobile production when you had to hope you did not receive an assembly line automobile built on a Monday.
In the case of Festool and its location, it may be that the assembly line elves, the Fabrikarbeiter spend a little too much time in the local rathskellers with their Krüge Bier on the weekend
Thus you have:
Montag morgen rathskeller Wirkung
So just hope your Festool order did not come off the assembly line on a Monday.
The corollary of this theory is the reputation of the local beer cellars is the real reason why FOG folks take in the Festool factory tour.
