Mostly a lurker here but desperately need your help on these doors.
These are nothing fancy floating panel doors to go on a painted storage
cabinet. When I dry fit the frames everything is flat and square on the
workbench and everything lines up. The panels when laid on the bench
are flat also. When I slide the panels into the frames for the final
dry fit, one corner or opposing corners will slightly bow. Have checked
all rails and stiles for squareness of cuts, groove for correct depth
and that the panel grooves line up. What am I missing? Any thoughts
and assistance will be greatly appreciated.
