I have completed the dovetails and glued up the box. I do have slight twist in the box. Paul’s box was twist free and he did little adjustment. With some pressure on two opposing corners I can flatten the box. Should I plane around a corner and flatten then box or take it out when I attach it to the top and bottom. If I use pressure and force it to lay flat when I attach the lid and base, will this increased force translate into problems when the lid has been separated?
I think that you can take out some twist if it’s bad, otherwise I would wait until after the lid and bottom are glued in place and you have fitted the ply wood bottom to the top chamber. All if this can also change the shape some. Once you have done that and the box is of course ripped down into two, you can better see how the box lies. Sometimes this can change the problem in your favour.
