Hi folks, I need some advice please.

While continuing my buffet build, I'm up to the doors (I hate euro hinges sometimes), and my second set of doors.
The first set warped badly once I unwrapped the wood, and cut the pieces to size. Partly exposure to humidity, partly I think the wood releasing some stress.

No matter, I cut my next sheet up that seems to be behaving well, and make my doors.
I also put a single coat of poly on to help seal it a bit while I finish working with it, as I don't want it to suddenly develop a case of warp also, as otherwise this is going to get annoying and expensive.

All going well, but I have a problem with just a small amount of warp in one corner, making the door corner sit out about 3mm proud of its mate. The doors are "book-matched" because they're cut out of the same sheet of glue-lam (18mm thick, each sheet 1200mm x 600mm)

Does anyone have any idea how I can coax this back to "flat" or what I can do to straighten this out? I really don't want to go through trying to obtain another sheet and potentially having the same issue.
Picture below taken "above" to show the warp in the top corner.

Feel free to ask questions. I feel like I'm so close to getting this done, it's just frustrating to have this happen now.

Hello Steve, I feel your pain on this!  Just went through some of the same pain on a couple of my kitchen cabinets.  Unfortunately, I don't have any sure fire fix but maybe someone can offer one up.

What I actually ended up doing was clamping the doors together with cauls for a few days prior to mounting on the cabinets.  I still ended up with slight warp on a couple doors.  The worst one I oriented the door with the warp at the top of the door (this was an upper cabinet) and with the handle placed low, you quite naturally look at the handle and that corner.  And too, my doors are painted and have frames.

 

How are y'all doing with covid-19 down there?  Been about a month since we've heard from you...

Thanks Cal

There will be no external handles on this, I intend grooving the top of the door to provide finger-pulls.

I'm contemplating clamping it down, but not sure if I can get any moisture back in to it after having put a single coat of water-based poly on. 

If it was rail and stile, it might be simpler, but these are solid wood glue-lam (matching piece to the table).

I'm considering a magnet up ion that corner too. Sadly it's not a matter of adjusting the euro hinges, 'cause I've done that to the max (I hate them things when they just don't work like you want   ). Otherwise I'm up to attaching a sturdy metal brace to bend it back permanently, or cutting a kerf and putting in a spline.

 

Covid-19: we're starting to come out of restrictions, hasn't been anything like the numbers elsewhere in the world (infections or deaths), so we're getting off lightly compared to some. It feels like they're rushing to get out though and too many people have gone too far already. My wife and I are in no hurry to mingle

 

How are y'all doing?

 

Are those doors plywood or solid?

Maybe this is a learning exercise and it might be telling you to draw up things that might hide warped wood in the future.....I got to where I couldn't get my wood safely home with out the sun helping the wood change shapes so I decided to only build things that was  curved by design....I even bought a camper shell so the 65 mile ride home in the sun would at least be in a covered pickup bed but that didn't solve the problem completely..

  Even if you find a way to unwarp wood there is no guarantee it will stay that way...

Some bright guy comes on an tells every one that wood grown on hilly terrain will always warp...….I don't know of any one who would spend big bucks to get all their land completely flat before they set out the little buggers that turns in to 2 x 4's.

Take the screws out of the lower hinge and hold the door closed by that errant cornet.  See if it don't tell you to move the screws some or add some spacer or both.  Spacing out the lower hinge out usually pushes the opposite upper corner in.

Hi John.

Solid timber - beech, sold in glue lam sheets, imported from Romania of all places.

Thanks Dan. If I do that (and believe me I've tried a lot of hinge change, although not moving the mounting screws any more), it'll likely mean the door spacing is then out at the opposite corner, which is not attractive.

It's only that top corner that has moved, and the opposite door which is cut from the same sheet hasn't moved.

I want to keep them aligned as this provides continuation of the pieces of beech across the panel, only minus the saw kerf.
