Apron thickness

    For my aprons, I’m using reclaimed scaffold boards, that are about 38mm thick, but a bit cupped. After laminating them, and planing them flat (a lot of planing !), I’ve ended up with aprons that are 33mm thick. Is this thick enough?

    Another thing – one of my aprons has developed some twist – if I lay it on flat surface, one corner is about 5mm high. It can be pushed flat with some light hand pressure. I don’t think this should be an issue – the apron will be bolted to the legs, and this will pull it flat… is that a fair assessment?

    Hello,
    I’m also a newbie and many questions but just to help you :
    – I think that 33mm is still ok
    – The legs won’t go up to the top of this apron so it won’t be enough to flatten the apron. But if it’s the one you’re gluing to the benchtop then it should be enough to have a flat apron.

    Well, these aprons are driving me crazy. I spent a longggg time flattening them, as the scaffold boards were quite cupped. 5 days after glue up and lots of further flattening, they’ve cupped at least as much again. By the time I plane them flat, I think they will end up less than an inch thick. Plus, what’s to stop them cupping more and more?

    I think I’m going to scrap them, and glue up some aprons out of several narrower pieces, in order to avoid this dreaded cupping that wider boards are prone to do. I think I’ll use three 47×100 glued up, giving myself an extra thick and chunky apron.

    Good luck,
    we’re all Learning woodworking and sometimes it seems that Nothing is going in the right direction.
    Maybe tyou could use your thin apron for your wellboard?

    Hi Ludo! Yes, one of the failed aprons will be given a new life as a well board. So in the end, I’ll not have wasted much. My first leg frame is all done now. Glue up was quite tricky – I’d done a dry fit about 3/4 times, and it was all nice and tight, but with the glue on, I just couldn’t get the tenons more than halfway in! I had to use sash clamps to drive them the final 50% of the way! Second leg frame is ready for glue up, so I feel I’m getting close now 🙂

    Thanks for the encouragement.

    My aprons are 35mm thick and the leg recesses I made them 15mm deep.
    If your aprons cupped and twisted so bad it’s because wood was not dry enough.

    Question: where do you live? I’m galveston Texas (about 70-90% humidity year around) and didn’t know jack about selecting wood at the time, picked the center of a tree for one of my aprons and wellboard. Long story short I spent three days of non stop planing and decided that no matter how much I planed off it was never going to be truely flat. Just measured and I’m at 37 mm total but it hasn’t affected structural integrity. The bow is a bit bothersome but hey, what can ya do? Learned a lesson and that’s all I can say about it. Learn to select your wood. The joinery process starts at the selection
