IPE glue

[gc3]

Poly glues do not stand up well to heat, Gorilla included.... West Systems Epoxy should provide the bond you need.......PVA's handle heat better, if proper machining is done. Also if you use a "mortice/tenon" type joint you will increase the surface area of the glue joint. All exterior panels we use for doors have at the very least a .625 rabbeted joint...even better is using a glue joint cutter which will increase the bonding surface by at least 4 times. No reason to leave material clamped for 2 days...after 1 hr most bonding agents for wood have achieved their strength...what you need to wait for is the wood at the bond area to return to it's original MC. Search the woodweb adhesives forum for more info on glues and the proper bonding of wood substrates.

Here is what you do, don't glue it. Ipe is available up to 12/4 K.D. If you need some width to your piece just tongue and groove it or use epoxy. If you do have to do a glue up, back up everything with screws. Just countersink your screws and plug them.

Justin...wood moves, mechanical fastners will not stop lateral expansion/movement...period.

Smith All Wood Epoxy works well even on oily woods.

Thanks for all of the advice folks.

I did try cleaning with acetone first and it just seamed to me the laquer thinner was doing a little better job of cleaning the edges.
I was taking the clamps off after about 12-14 hours of wait in a climate controlled area of our shop.

On this job, I ended up getting a good enough bond with Titebond II. It was a glue up of edge jointed IPE deck boards that I machined sponsor names into from one side. After machining, I flipped it and cut pocket screw holes every 6" along the joints. I used the shortest pocket screws I had on hand.

I had a small piece that I had previously cleaned the edge of laying next to a few uncleaned scraps... after a few days I noticed that I couldn't hardly tell the difference. I think the "oil" seeps back to the cleaned surface... maybe a result of certain temperature conditions because it has been cold here the last few weeks.

Thanks for all the help.
