I can get cabinet grade 5 ply in other veneers such as oak or cherry, so that isn't a problem. The issue is trying to hide the screws/brads that will pepper the exterior during construction.
Here's some ideas I've considered:
1. Veneer over ply. I've never veneered before, but my research has found that if one must veneer over ply, it should be against the grain of the substrate. Would it be a big deal to go with the grain? The THTLP's will be upright, and horizontal veneer won't be aesthetically pleasing, IMO.
2. Veneer over MDF. MDF/particle board is the preferred substrate for veneer. Particle board isn't an option. What about 5/8" MDF for the exterior with 1/2"BB for the inner workings? I know MDF is discouraged for a number of reasons (weight, difficulty of use) Is this a reasonable compromise?
3. 5 Ply with preferred veneer, and another joining method. I realize the brads/screws simply hold things in place for the glue. What about biscuits or Domino tenons? Will they work with only 1/2" ply?
It's only me and my dog here (for now), but I want to give my THTLP's "high future WAF"


Your ideas are greatly appreciated!
