I don't know if I have any special hints in adjusting the aluminum extension
table. It did take me some time and quite a bit of fiddling, but I got it to
fit right and it doesn't sag. I think if you hold it up by hand so it's
flush with the machine table and then adjust the screws it may help. Seems
to me that's what I did ..but it was over a year ago and I don't quite
remember. Good luck!
