I am about to glue up a mahogany door. All the rails and stiles are straight and the fix seems really good with tight joints. I will be using 6 pipe clamps, 2 at top rail, 2 at lock rail and 2 at bottom rail all with one on top and one on the bottom. When all is tightened up I can make sure the rail and stile are in same place by using a straight edge across from stile to stile. I know the stiles are not a skewed (as if the bottom clamp is tighter than the top pulling the edge down).
I looking for a trick or tip to make sure that one door corner is on the same plane as the opposite corner(twisted). I can not put a straight edge because the pipe clamps will be in the way.
Anyone have any helpful tips on this so I can make sure the door does not get twisted during glue up.
