Type II pva and Western red cedar5/10/20
This a follow up from a few threads in the last couple of years.
Obviously, you have it right for gluing for width and joinery.
If you have not un into any complete glue failures, you are lucky.
Before I realized why PVA and WRC did not spell god joints, I was dumbfounded. Laminations in clamps for 30 hours come apart with wet glue like it was just clamped 30 seconds ago. Mortise and tenon joints where one is strong enough to destroy the wood when 'diassembled' and another shows wet glue.
Since I had the conversation with a Titebond tech, he explained that some WRC was showing a high amount of oil extractives. About 25% of the WRC they tested had enough oil to repel TB1,2,3 - as well as any other water based glue. Their solution? Wipe off the surfaces to be glued with paper towels saturated with acetone. Keep wiping until no brown (oil extractives) would show up on the towels. How does one know which boards to wipe down and which ones are OK? Wipe 'em all was his answer.
I admit that I have been telling people this for a few years, and all I get are looks like I am crazy. Most field carpenters here cannot spell "Learn your craft" much less live it, so they continue to do what they want. Other mill people will not talk to me, afraid I will abscond with all their knowledge and go make $40k a year instead of their $35k. So
I can't say I have had anyone else observe the same results I have.
I don't make a lot of doors .I was shocked to find trite-bound goes soft when it gets wet .I was lucky only used trietbound on my front door .
The other doors I used Elmer's ProBond Max Wood Glue, Interior/Exterior .The glue was thick which I really like.
One thing I did was add a little PL when I was gluing which expanded the glue which in turn forced the glue in the pores
No failures fingers crossed .I've seen some of the doors I made 5 years later no open joints like my front door
Another thing I did by accident [what mean is could not get 8/4]is use 4/4 African mahogany laminate 3 pieces the door ends up being 2 1/4 thick
I will will wipe great idea
Also thanks for the heads up I would not have had a clue ,about the glue unless I read the post
I've glued a lot of WRC with TBond III, I've noticed it's the darker color pieces that the glue doesn't hold well.
I've been making cedar signs with WRC for almost 20 yrs. I use LePages "Outdoor Weatherproof Glue" now exclusively. Never had a glue failure - even signs left "raw" (without any kind of finish/varnish etc.) No special prep. Inexpensive and widely available.
