I am building a coffee table with two drawers in it.  I cut up all the wood for it early in summer and had it laying around.  after I put it all together I found out that the plywood for the drawer bottoms had warped so the drawers dont really fit right. Is there a way to un-warp them? or take some of the warping out of the drawers?  the bottoms are already nailed in and would be a pain to take back out.

Plywood is usually fairly stable, but not perfect. Did you finish both sides of it in the same way? FInishing only one side could cause warping, either through contraction of the finish, or uneven absorption of humidity caused by the finish being only on one side.

If you can support the bottoms, you could try laying them out with some heavy weights in them to try and get them to reform the shape. I don't know how you have the drawers built, but If you DO disassemble and re-assemble, I'd use glue rather than nails; if your sides, front and back are square it's hard for the wood to warp and pull. Not impossible, but hard.

I havent put any stain or anything on the drawers yet I have tried useing steam and then clamping the drawers flat hoping that as they dry they would go back flat.

If PW has warped, it generally stays warped--- unless glued and screwed to a flat and stable sub-base.

(Plywood should be stored flat.  When PW is stored verically, it will warp).

I'd suggest replacing the drawer bottoms and use 1/4" MDF or pressboard, and sealed with schellac.

Alternate fix::

a. add a 3- 4" wide solid hardwood strip, on the underside of the drawer bottom, orientated

front-to-back---ends butted to the front and the rear drawer member.

Fastened in-place with glue and brads (brad nailer). 

(Clamp in place, so the surfaces are making intimate contact,  'til the glue dries), or

b.  Insure the drawer is ''square".  Install a 1/4" MDF or pressboard insert panel, cut-to-fit snugly, on the inside over the drawer bottom.

Glue the insert in place---add adequate amount of weight to keep the panels sandwiched while the glue is drying.  
Apply an 1/4" bead of glue, spread out evenly, should be adequate.

The bottom drawer which was the worst I cheated by adjusting the drawer slide strip down enough so that when the drawer is closed it looks normal. The top drawer there isnt much I can do for that one but that drawer isnt to bad.

Top Drawer:

attach a sign, "DO NOT OPEN"  ; )

Lol the table is like a shadow box with a glass top so the top drawer will hold stuff from our wedding so it wont have to open really :-)

Miter Saw Recommendation 1 Reply

I’m looking to upgrade my miter saw. I’m willing to invest a good amount of money to get one with the precision pocket hole joinery requires. Would anyone like to offer a recommended model?

New Kreg 720Pro

I saw the video Kreg put out for this new jig and had high hopes for it.

I purchased one today and am very disappointed with it.

First the docking station is extremely cheap. The plastic is pathetic. A Lego has more…

Not Pleased With Pocket Hole Construction

Several months ago, I purchased the Kreg K4MS so that I could build the Lego Table as outlined on the companion "buildsomething" web site which exclusively uses pocket hole construction.  I have considerable experience with conventional…
