Glue Creep on solid lumber7/1
Can anybody tell me what is happening on this drawer face?
We built it out of 1 inch rough poplar then planed and wide belted it to just over 13/16 inch. There are three laminations and we used titebond 1 glue.
We've been building drawer faces this way for a very long time. We have literally 100's of drawer faces out in the community that were built this way but none that manifest the joint between laminations so severely.
I don't know exactly what the paint protocol was. Could it have something to do with the glue we used? Could it be that the glue was not cured enough before we thickness planed or sanded it?
Forgot to post pic!
I've had that happen to me a few times, usually when I tried to rush the time between glue up, planing, and wide belt sanding. I think the joint swells slightly from the water based glue and then recedes as it dries. Now we always wait overnight before planing and another day before sanding. Softer woods like poplar and alder seem to be more prone to this.
Yup, to quick to the thickness sizing.
It actually takes about 3 days to get the moisture that the wood absorbs from the glue out of the wood.
You'll need to wait at least 24 hours.
Thanks guys. That's sounds like a real logical explanation.
I would not call this "glue creep", though. I don't think there is a term for this problem.
Glue line creep, as I would define it, is when a cold bent lamination is glued with a glue that will allow the finished part to straighten out a bit over time. Such as a handrail bent to a tight radius with TBIII as the glue. This is different from springback. This creep can allow a part to loose its accuracy. I have had 8' radius twisted handrail not only straighten to 12' radius or so, but also loose its twist - within a week. It would no longer fit the form it was built on.
We have enough confusing or missing language the way it is, so it is nice to get some clarity when possible.
If you will be at IWF this year, I will be giving a seminar on gluing, including this specific issue on Friday. Check the program for times, etc.
