I’m building a frame & panel blanket chest and the prototype is nearly finished. I’m anticipating the finishing and assembly process. I would prefer to finish much of the frame before glue-up, but am worried about protecting the mortise & tenon joints from whatever finishing steps that I’ll undertake (the frame will likely be cherry with birch, maple, or white oak plywood panels finished separately).
The finishing scenario for the frame could include:
1. A diluted shellac wash to seal the wood (necessary on cherry?). How about Waterlox?
2. Tung oil, alkyd or polyurethane varnish, Japan drier, and mineral spirits wipe-on.
I can wrap the tenons with painter’s tape, but how about the mortises? I’d welcome advice on the do’s and don’ts of the process. This is my first attempt at frame & panel joinery and I don’t want to inadvertently compromise the final glue-up with contaminated joints that won’t take glue (Titebond Extreme).
Many thanks in advance.
