I am new at woodworking and I am trying to make a storage bench to sit at the foot of my bed. I saw a photo of one and the sides curve inward like a quarter moon shape and then it's entirely upholstered.
I bought a jigsaw and workbench and drew my pattern for the front piece and cut it from 1/2 " plywood. Then I cut the sides and found obviously that there is a big gap at the corner where the pieces don't meet. I have no idea what to do now..I need help please!!!!!!!!!!!!!

Hi dmd,
I am a bit unsure of the problem without seeing it firsthand. I would guess that you forgot that when you bend a piece of ply or anything else for that matter it becomes longer that the flat piece. A radius line is longer that a straight line between two points. You will need to measure along the line of the radius to get the true dimension. If you can, send a pic to me at bobvila.com and I'll look closer......Mark Hammond

From your posts I'm not sure if you want to redo the curved piece or fix what you have. To do the bending, the best practice is to laminate multiple layers of 1/4 inch plywood.
Create a jig with the correct radius. Bend the first sheet, apply glue and laminate the second sheet. Use lots of clamps!!

Make it oversize then trim to fit afterwards.

If you just want to correct what you've done, cover the gap with wood trim so it looks like you planned it that way.

Bob..I couldn't add trim..the gap is huge but what if I wet the plywood until it delaminates and then follow your instructions and put it back together a layer at a time? Thank you very much!

No - you'll end up with a big mess. 1/4" isn't expensive. Just use new sheets.
Go to a big library and check back issues of Wood Magazine. The've had several projects over the years where they've bent plywood. Two I remember are a sleigh bed and a bobsled.
Their site is www.woodmagazine.com

Hi again,
Bob's suggestions are right on the money but consider the type of ply you are using and try and do the bending with the grain. There are plys to contend with but there are at least two more in one direction than an other and it's easier in one direction. If this "goes against the grain" that you are trying to work with then.....Mark Hammond
