Gluing Oak....

[Rational Root]

I know this had been done to death, the whole white oak & epoxy thing. But I have a two questions.

1) Has anyone come across this

http://www.star-distributing.com/smith/oakandteak.html

Apparently it's an epoxy specially forumlated for oak & teak. Being naturally cynical I'd love to hear of anyone's experiences rather than simply taking the producers word for it.

2) Being a beginner, I'm faced with

a) Use epoxy on white oak and it may fail. But I don't mind since I'll have bronze screws all over the place.

b) Use Resorcinol:
I'd better make my joints accurate, and I need to keep it warm (not going to happen out of doors in Ireland in winter, I can bring the individual frames indoors, but not the whole boat.)

c) Use Balcotan:
I still need to make the joints accurate, but I don't have to worry about the temperature.

Have I missed anything here ?


I'm leaning towards Balcotan as it isn't 70F here in the day time never mind over night. Unless of course lots of you folk come back to me and say this new oak and teak epoxy is a gift from above and you all love it more than good red wine.

Thanks

I'm not sure I like it better than good red wine, but I've tried it on several joints and it has held well. It hasn't been long enough for a 100% test, but Smith & Co. has some good testimonials. As for temperature, the claim is for use down to 28 deg. F.
If temperature can be controlled, I prefer resorcinol for anything that can be clampled tiighty, but if clamping is a problem I would go for the Smith & Co.'s oak-epoxy glue.
What is Balcotan?

I was hanging out on the schooner virgina today, and I couldn't help but notice that she has lamenated oak frames... laminated with resourcinol...

Did you just rough sand it ? Or did you wet it out with thinned epoxy first ?

20 deg F - that about 2 deg C. That's kinda chilly. Ireland is never either very hot or very cold. So I could probably use that most days over winter.

Thad, those glued laminated timber white oak frames and other members on the Virginia were manufactured with phenol resorcinol adhesive. Of course they were glued at elevated temperature. The members were made at Peshtigo, Wisconsin by Sentinel Structures, Inc. www.sentinelstructures.com

We just shipped the last of 37 truckloads of white oak glued laminated timber members to the new US Census Bureau office building in Suitland, Maryland. 16,000 pieces of finished material. Nearly 700,000 board feet of raw West Virginia white oak lumber went into making these straight and compass timbers.
