Anyone glue one of your projects up and it was fine when you left it but when you returned it was all out of shape. Boy this just burns me. Just did a job and it was square. Not anymore. Did the job all over and at my cost. OUCH How do you stay square. I know the tricks but I did not do what I know and it cost me. Lets pass along our tricks to stop others from my mis fortune.

That cost me 450.

What was your project? Maybe your wood just warped. Give a bit more detail about what exactly happened.

Warping is the greatest factor in a wood that cause it to move. During glue up, clamps are not enough to hold the joints in position. SPRINGBACK will also be a big problem. Supports and brace will likely be useless if the wood is warping. When I make a table… I just don’t worry on these things but just join the pieces together and let one from the other help its other to make it stand square. But I consider how strong each element to hold it.

TRY THIS…. Wet or spray water on the wasted unsquare then clamp them square. Wet again and then retighten clamp if necessary… Let it dry by itselp while clamp. If need be.. you have to overshoot clamping to overcome the springback…. then that will save your 450.

Its not the fact I don’t know what I did wrong but really what I know I should have done.I cut corners and it bit me in the butt. Just getting more peoples ideas on how to hold their projects square is all. Project was a cabinet and I did not use any device to hold it square while it dried and of course the end result was not good.

Bummer…...glue, clamps, and a nailgun plus a trisquare or rafter square would have helped….Dry fit first to check for square, then measure corner to corner cross-ways, and proceed once everything is square.

I have a few of the framing speed squares from Harbor Freight. I nipped the corner so it stays out of any squeeze out and clamp it inside the carcase, beore using the bar clamps to pull the joint tight.

You might want to try as Deke mentioned using clamping Aids. I often will use clamping squares in my clamping process. They can be made from wood or metal or can be purchased. An example of a clamping square here.

I use these often when gluing up cabinets and frames along with my clamps.

Were you using regular old f style clamps or were you using Bessey or Jorgansen self squaring clamps?

Harbor freight clamps, and they came off too soon cause I needed them for the next glue up. Needless to say I will be buying more clamps and making some squaring blocks.

Hope this might give you an idea. I have used this type of setup for about 30 years. I have a set of four of these to glue up cabinet sides to base, or anything else you need to hold square while the glue drys or until the back is on. I made mine with 3/4” apple plywood or any quality ply. Of coarse you can make them what ever size you like, mine are 18”x24”,which works well for most cabinets. I usually just leave them clamped until they get in the way. If you are careful to make them perfectly square they work great. the notches in the bottom corners are for easy cleanup of glue. Sorry to hear about your loss of $$$. We have all been there.
