Hello friendly and knowledgeable people of the WWMC forum.
I am building Langstroth beehives from Western Red Cedar. My local timber merchant can only get WRC in 6×1, which is fine for the shallow honey supers, but for the deeper brood boxes I will need to laminate two boards together. I was intending to edge joint as usual, plough a 3mm groove in each edge and slip in a plywood tongue during glue up; but as these will be totally unfinished, tolerating huge swings in moisture levels and full of angry bees I thought I’d see if anyone had advice for making sure these joints never come apart.
Any suggestions for a good glue to use and a sound joining method greatly appreciated.
Thanks!
Chemie,
I built my Warre hives from Cypress and was able to find wider boards, however the WRC will work just as well if not better.
For edge joining I’d probably use Titebond III or similar.
Plain rubbed joint, biscuits, spline, tongue and groove……I’m not sure it really matters.
One problem with the plywood spline might be fitting the groove to the ply thickness for a good fit–food for thought.
And for what it’s worth, I’d put some finish on the outside only, for durability.
Best,

I was a little surprised I couldn’t get wider than 6in, I understand the trees are enormous.
Good call on the plywood, it’s tripped me up before but I know this particular size works. You get 3.5mm standard in the UK, which you can plane down to fit a 3mm groove tightly. You don’t usually go through the outside plies if you’re careful.
And it’s Matt by the way, chemical_cake is not my real name.
