First real post after buying a Domino 500 yesterday, my first Festool tool and yes am i excited
. I have read all the manuals including the supplemental and watched many videos including Peter Parfitt's excellent video. I cut up a whole pile of scraps to practice and most of the joints are near perfect which put a smile on my face. Occasionally one was slightly out (probably user error) so i thought I'd try making the first one tight and then all the others on the middle setting as seen in many videos. Here's my confusion! Should the 2 tight fittings on each piece lock into each other or should the tight fitting on one piece mate up with a loose fitting on the other. One video said the 2 tights should match to avoid rotation but when that happens I don't seem to have any wiggle room which is the wole point of changing widths.
For those of you who adjust the widths for most joints which way do you do it. Tight to Tight or tight to loose?
