Shiplap back question.

Shiplap back question.

Lee

Back is shiplaped Ash, pieces are 4 and 5 inches wide.

I have already finished the pieces with a water based polyurethane.

Wanted to put a little blob of glue on the centre of the board at the top and bottom, brad nail in and let dry.

This should still allow the pieces to expand and contract.

I will then pre-drill and add a nail later.

Wanted to do it this way so my gaps are nice and even. Didn’t trust myself to hold the board nice and still while I pre-drilled for the nail.

I want the gaps to be perfect from the inside of the cabinet.

What glue will be best for water based polyurethane to bare wood connection?

Or blue masking tape to hold them temporarily?

Will epoxy work?

Make little pieces of shim stock and put them between the boards to keep the gaps even for drilling. Pallet strapping is uniform and easy to snip up for shims.

just in case you get it wrong, you get too much expansion or shrinkage later, or a board splits and has to be removed later for repair, etc., hide glue is failsafe.

Epoxy, OTOH, is overkill.

Unless the boards are all from the same tree and have the exact same growth ring orientation, the expansion rate may vary slightly from board to board so that seasonally the gaps may be less than "perfect." One of the features I like about wood is that it is not perfectly uniform, but that's just my opinion.

That is what I do ...

Derek Cohen (in Perth, Australia)

A spacer between the parts to set the gap ...


and then they are screwed about 1" from one end only, which allows for movement (no glue) ...

Take a look at Telegraph because their articles have helped me a lot with shiplaps. I think that you have a pretty common issue so I'm 100% sure you'll find a solution there
