DAP Weld Wood Plastic Resin

[BMorv]

Based off a recommendation by Pat B, I bought a 1 lb container of Weld Wood on amazon prime for $9 ( I think the price went up to $12).  This past week I was able to glue up a tri-lam with it and here's my findings:

Pros- Cheap, Easy to mix just add water, good consistency, good open time to apply clamps, it's in a powder form so it should have a long self life, good glue lines, and it worked great on my tri lam.

Cons- They only offer it in the dark brown color, and it didn't spread as far as I expected.  I ended up having to mix another batch in the middle of the glue up, so it was nerve racking, but it didn't seem to affect the end product.

It performed in much the same way that uni bond 800 does, and for the price, ease of shipping, and hopefully long shelf life, I'll definitely be using it again.

I guess it's ok..

I built a boat with that glue. It's good stuff. It has a long working time and you can mix it to the consistency you want.
Nice bow BTW.

Thanks, but the bow isn't done yet.  I'm still tillering it.  I'll post some pictures with the specs when it's complete.  
And a pre-thanks to Roy, as you can see I "used" a lot of his techniques in building this bow.

I use it, very tough glue.  I found out a couple times that I mixed it weak by accident all the lams flew apart.  Its expensive up here and hard to get, so i only use it for gluing up handles/risers.  I use TB3 for the lams as long as the surfaces are flat, clean and sanded properly no problems.  I  have a couple bows with over 1000 shots and showing no signs of de-lam thus far. I would not use TB on Bamboo.

Yeah that reminds me.  It's 5 parts powder to 3 parts water if you are measuring by weight.  I was surprised at how little water was needed to make the mixture.

I get 1/2 gallon of unibond delivered for $ 30 bucks. Makes 20 bows.

Does it work on gwass?

[Roy from Pa]

LOL, who cares...

[Pat B]

A friend on PA sent me a nice bunch of WPR. I got it today but not quite ready for glue up on the hickory backed lemonwood ALB I'm making. I've used it before with good results.

[BMorv]

LOL, I'm not sure if it works on glass.

If unibond would last, I would never have tried another glue.  I don't have enough room for a half gallon of glue in my refrigerator as it's filled with beer    :D

[Pat B]

Unless you make lots of bows you are better off with a small container of glue. IMO  It might cost a little more initially but if you have to throw it away, you haven't saved anything.

I have thought about using Weldwood on a bow once my unibond is used up but my concern is will the water used for mixing soak into the lams and cause problems. My thinking is once the water is in the middle lam with the glue joints how is the moisture going to escape the wood? so what was once a nice dry hickory lam is now a wet hickory lam not to be dry again anytime soon effecting performance. Maybe I'm just overthinking it. I have used the stuff for many other projects including a couple boats and when I am bending laminations to make a curve. But none of these get flexed to the extreme after the glue up like a bow does. The stuff works great and I can get it locally so that's a bonus.

Benton, I could stop by and help ya make room in your fridge..  

[BMorv]

Hahah.  Well hurry up, the beer just got demoted and it's started to get warm.  This little piggy went straight to my fridge

Awesome...

Ringbill, I really don't think water is an issue.  The water is used as a catalyst to start a chemical reaction.  Once activated and mixed properly, it becomes a urea formaldehyde glue and the water will no longer be able to be separated from the other components. Here's the spec sheet:

Thanks for the spec sheet.

I've been wondering the same thing as Ringbill about the water.
I'm remembering something LittleBen was saying about using titebond...about how long it took for the moisture content to get back down.

It is a tempting alternative otherwise.

Why don't some more of you guys start using it and tell us all about it...lol
