My first posting… When I glue up raised panel doors (or rail and stile doors with a plywood panel) I have a hard time keeping the door flat. Square is not a problem. When I then fit the door flush into an opening one corner or another is standing proud or is recessed. Is there a way to assure a flat assembly?
Thanks for any and all suggestions,
MW

Mark, it sounds like you have either of a couple of problems: 1) Are you sure that your cuts on the stiles and/or rails true 90 degree cuts? If you are butting one that's not at 90, it will kick your door out of square. How are you securing the joint? Pocket screws, or glue and clamps? If you clamp too tight, you can warp the door.

Thanks for the input. The stock was prepared (jointed and planed) square and the cuts were double checked for square as well. I think the clamping pressure might have been too high. I'll take it easy on the next glue up and see how it goes...
I appreciate your help,

Mark,
The best way to make sure of the pressure on the joint is to (after you make sure that the two boards are true to each other) clamp them just enough to squeeze a little of the glue out of the joint. Too much pressure will do two things: push all the glue out of the joint, and warp the joint. Good Luck,

Are you jointing / planing your stock to get your pieces square before you put the cuts on? It sounds like what you'd get if you just took off the shelf lumber, put it through the saw for width and went to the shaper. If you're doing that right, I'm out of original thoughts.
Is your glue up table flat.
Fred,
I just glued these up on the bench. I'll double check the flatness..
Thanks for the input,
