any suggestions on fixing this problem

Not sure what would be the right name for this.made this today and it bowed like crazy anyone have any ideas of how to fix the problem?

[Scrappile]

I'd lay it face down and put weight on it.  Leave it that way a week and see what happens.  While waiting make a new one, just in case this doesn't work.

No help to you on this one. What works for me is to make the interior cuts. Glue the fret piece to the backer, put a bigger, thicker board on top with a LOT of weight on it. It will glue together flat. Next day, cut the perimeter.

 

Hope this helps next time Friend.

That's a wicked bend for plywood,unless it's bending plywood.I have some but so far never needed it,I have this problem with thin 1/4" wood that is glossy on one side for drawers.I stay away from it like the plague.

Maybe if it said Chicago Black Hawks it wouldn't have bowed.

Set it in the sun and watch it close. It might work and it might not.

Hi

 

I once had this problem when using plywood, which is my material of choice for portraits. This happened to me when I tried an experiment of transferring the pattern onto the plywood instead of using a regular paper pattern. I tried ironing the transfer on and the heat gave it a major bow which made it impossible to use.

 

I can't give you a solution as to how to fix it except turn it over and weight it down for a week or so but the bowing might be heat related so if you store your material in a hot place, try changing it to somewhere cooler.

 

Don't know if this will help or not but just giving my tuppence.

 

Cheers

Todd, what is the material you used to make this out of, is it just plain plywood? Was there any bowing in either piece, before you glued the two together? When you did the glue-up, did you lay the project flat with weight on top of it to keep it flat? Looking at it, it looks as if the side that has had paint applied to it, is causing the bowing. You may be able to correct it by painting the back of the backer, and by adding a poly finish to the front of the piece. Don't try to use a water base finish, it has to be a poly or lacquer type. Don't apply the finish to the front or back of the item, until you have a way to clamp or hold it flat. And then, only apply the finish to one side, either the front or back, it doesn't matter which is done first. Let the finish dry until it is good and dry, then finish the other side. The main thing, is to keep it clamped flat for this to work.

Recut it..........

[Lucky2]

I agree with Larry, it would be quicker and easier to re-cut it, rather than fix it.

Hi Newfie

If you really are planning on keeping it

I would try to screw a piece, possibly two strips of hardwood from the back

You could screw it along the outside edge

 

Another team would definitely solve this problem as stated above............LOL

I read an article a while back about ply warping. Sait to wet it with a damp rag and add wieght to help control  the bowing action. Never ran into this myself but would think it is worth the attempt. Best of luck. 

[lawson56]

Now I have ran into this problem with Hard wood,White pine.I just turn it upside down place it in the sun with a heavy weight,and let the sun do its job,Will it work with Plywood?It should.

[Birchbark]

lay it face down on a damp rag.  the moisture will cause the grain to swell on that side causing it to flatten.  Pretty much what Len was saying.  You got the back wet, which caused that to swell longer than the dry front.  Equal the front out and you should be good to go.

Hair dryer also works

Get yourself a large beer barrel and place it on top with a glass in your hand and sit there all night drinking and you'll see it straighten before your very eyes, works for me.    Roly

sometimes the use of a heat gun on the wood can help. I have done this and it has worked for me.. I am not sure about the proceedure but I believe that you heat the covects part and the makes it expand. maybe worth a try.. you don't want to hold the gun really close, hold it away a few inches and let it hear your board slowly and see it that helps.
