| Finishing wooden jigsaw puzzles I make strange and different wooden jigsaw puzzles. There are no pictures, no straight edges and no fixed shape, no up, no down. I cut the puzzles from glued up panels of different kinds of tropical and native hardwoods. I am trying to decide how and when to finish the puzzle so as to protect and enhance the appearance of the wood. If I finish before cutting I risk damaging the finish during the cutting process. So I think That I need to finish after cutting because sometimes I have to sand the bottom of some pieces to remove tear-outs.
Once the puzzle is cut I assemble the puzzle. Then I have to apply the finish to the top and the bottom. BUT I do not want the finish to stick the pieces together. I am thinking about oils or waxes.
Any thoughts or advice would be appreciated. |

| I have cut prefinished wood before and had no problems.
If you use cardboard on the bottom of the wood as you cut you will elliminate tearout

| G'day Ed,
You can go Carl's route and shouldn't have a problem.
The way do it is use a spray lacquer, 2 or 3 coats, cut back between each.
I've never had problems with the pieces sticking together in with any permanency. What I mean by that is when the lacquer dries the pieces may be stuck to each other but a slight tap on the edge of the puzzle breaks them all apart. |

| The best way learn is to make some puzzles and figure it out on your own. Expect to make a test puzzle or two, and finish as you choose. You are the artisan here.
But, if you finish after cutting, you can expect the finish to get into the space between the pieces of the puzzle (the walls of the blade kerf.) If you are using a very fine blade, a thick film finish (varnish, poly, acrylic, shellac) may impact the fit of the pieces. Also, there will be a lot of piece to piece contact as people assemble the pieces. If you use a thick film finish, the is the chance that a flake of the finish will dislodge from the side of the piece.
But in your unique puzzle making technique, this may be of minor importance. You may choose a very hard thin film of lacquer to be the finish you want and to heck with the odor and dust mask problems.
