Need help with built up top/bottom for veneered cabinet3/30
Hey Folks, I'm making a cabinet with a thick top and bottom, sort of like you would see on a Krenov cabinet. Theses pieces of the cabinet will be 2.75" thick by 34"x22". I could use Baltic birch ply built up to make the thickness, but they would be quite heavy. I'm using shop made veneer about 3/32. Would it work, be stable, to make a sort of torsion box for these pieces?
Thanks for the help!
I would use solid wood. Those are not very big pieces at all, in the scheme of things.
Bill, besides the weight, I would worry about a veneer that thick pulling the face off of a plywood substrate. You have no idea how little amount of glue was used to glue the plys together, but it is not likely to be 100%.
I'd much rather glue it to a mdf or pb substrate. Or a solid wood, with similar properties.
torsion box would work fine, I usually start with 3/32" thick sawn veneer and then it finishes around 1/16".

So consensus so far says no to BB ply, although I've never had any delam issues with high grade BB. I realize these are not big pieces, but I would prefer them to be lighter and stable. Not sure a solid wood substrate would be suitable as I need to edge glue much thicker banding, which would be to end grain in that case. I need the thicker edge band to sculpt a profile.
I suppose MDF would work in a torsion box, never been excited about using it.
Any other thoughts in accomplishing this?
Thanks again for help.
Using shop made thick veneer I would be very concerned about a torsion box warping. I personally would use MDF glued up to get your thickness and then veneer on that. Will be kinda heavy but I don't think you can get around that. My 2 cents
I think I'd build a torsion box using 1/2" MDF for the top and bottom skins. I wouldn't use any thinner than 1/2" if you plan to veneer it in a vacuum bag. MDF is an ideal substrate for veneering as long as it's not used in a structural application.
