will glue n screw with titebond iii be enough?

[Grid Runner Adventures]

hi guys will titebond iii and screws every 4 inches be enough to keep walls together at hwy speeds this will create a strong torsion box. also what can i use for filler before i sand and herculiner the whole thing ? how about titebond iii mixed with sawdust?

[caseydog]

The glue is going to be doing most of the work. The screws just provide a mechanical backup -- and keep it together while the glue dries. Plus, when you get everything closed up, there's not going to be a way for wind to get in and "pressurize" the cabin.

Screws every four inches is probably serious overkill, but if it makes you feel better, go for it. Just be accurate with the screws -- don't split any wood.

I glued and screwed my walls to the floor and I put a screw approximately every foot.

This is what happens when you take out the screws and try to pry apart a wood frame that has had enough Titebond III used. The wood gives before the glue does:



And, yes, sawdust mixed with Titebond III makes a handy filler.

years ago the govt. spent our tax dollars to test glues. They tested lots of them but found white (elmers) glue to be the best for wood. Now we have others and titebond is an even better evolution of white glue. Titebond three is pretty much the same except water resistant.
i.e. If a 2x4 is glued together properly with titebond and clamps by overlapping 4" and you try to break it. The break will always occur someplace other than the glue joint.
I make guitars. The neck is glued on with white glue. The glue holds a huge amount of tension from the strings.

When you use screws to hold a bonded joint; the screws act as clamps. Once the adhesive has set, the screws can be removed.

you'll be just fine with glue and screws - But I echo that every four inches may be overkill on the screws. But to add to the conversation - on the ladybug , I used 3/4" serrated paneling nails to hold the exterior 5mm luan ply to the wall framing while the titebond glue set - no screws showing through and them little nails ain't coming out!

K now I am feeling all fuzzy inside now heh that titebind iii is amazing stuff, I got a gallon of it when I started the build and I might come close to using it up on this camper!

Last big question I have, I need to find a 2 inch aluminum T metal any ideas?

[Grid Runner Adventures]

err 1.5

I need to cover the edge of 2x4 and the wall joint. so that actually be a 3 inch metal 1.5 on one side of T and 1.5 on the other side of T

titebond is very good glue but it is CABINET MAKING glue. it's not meant to withstand dynamic loads.. for critical joints (sides to floor etc) PL Premium is a much better choice.. it's also a lot cheaper.

[Grid Runner Adventures]

I have pl200 that I was planning on using for the walls to floor joint along with a T metal. as soon as I can find a T metal heh

A good glue joint is stronger than the surounding wood. This is a break test using Titebond II.

[Jst83]

Yes Titebond is great stuff, I started out using liquid nails and switched after a test and it sate up quickly and wouldn't budge.

Speaking of Titebond III – has anybody tried to use it to wet out fiberglass? I think when I try doing some panel tests I’ll include some Titebond specimens just for grins.
