Thanks for the comments.
Steve: with solid wood banding, do you get the banding flush with the ply on both sides (inside and outside the box)? Given that there is a tiny variation in thickness of ply I think
this is next to impossible but I guess it doesn't matter for outside of the box (only flush inside is important).
So it appears the options are:
- Use solid wood edging (like Steve)
- Use the same color pre-finished edge banding as the ply, so all the box is the same color.
- Use a pre-finished (same wood species) banding, but this might not have the same stain/finish as the doors
- Mask all the box (after applying the banding) and finish them (which doesn't seem easy and I suspect won't give the best results).
I am surprised, I thought there should be a standard and easy method for all aspects of kitchen making by now (especially for frame-less boxes as they are supposed to be faster and easier to build).
