Gorilla Glue again

[Bootlegger]

  I am looking for some advice using gorilla glue, I posted in the building section and Fred replied, but I don't have any experience using the glue, so I thought I'd post here also.
 Does anyone have experience using this glue, I got some white and glued some Styrofoam cups together and they are holding, but I haven't used it any where else.
  So,  any help/suggestions will help, Thanks a lot..

             I use it all the time for foam wing joining. Best advice, it's not yellow glue so don't treat it like it is. You only need a thin bead down the middle and wet the pieces prior. I also like to use my pin vise to poke a series of holes into each root end to assist in offering some bite. This also gives the material a place to go when expanding.  Wetting it kicks it off and makes it expand more. It works better when clamped. It's heavy so don't go overboard and treat it like epoxy. Don't get it on your hands and don't disturb the joint after a few minutes.I use clear packing tape stuck firmly over the joint when the halves are applied together. I then iron the tape down directly over the seam. This keeps the stuff from oozing out. You essentially have similar working times as you would using 30 min epoxy. We all know for instance epoxy offers a bit of flexible time to work with it, just don't miss the window. My clamps are comprised of 2  1/8" pieces of plywood which are about 3"x 3" . At the end of each piece of ply I drill a 3/8" hole and through the end. The other end  I use 4D finish nails drilled through the ply wood. I join the two pieces with rubber bands through the 3/8" holes, stretch it across the root and push the finish nails into the foam. This pulls the root very tightly together so doing this on the top and bottom is imperative adjusting tension as needed by stretching while sighting the leading edge for straightness.

Ken, it sounds like you're joining foam wing halves without sheeting them? Or do you just poke those 4p nails into the balsa sheeting? Stunt or combat? I love your avatar!  Steve

Gil, Doc Holiday has used this glue for a long time and would be a good source to give you some advice as well.  I have never used it so I cannot comment.

White gorilla glue expands to have similar properties to medium balsa, maybe ligher.  I have fixed some rushed sanding errors in a leading edge by building a mold from several layers of masking tape after pouring in about 1/3 the volume of the error.  I did not need to sand when I was done, just painted after the tape removed. 

I have tried using brown gorilla glue on non-modeling tasks, and have found it structurally unsuitable if cut or carved.  I made 2 kayak paddles...one with gorilla glue the other with yellow wood glue.  The gorilla glue paddle fell apart at the joints in the thin blade area, so I started over with yellow wood glue (Elmers iirc) knowing it could tolerate being carved and heavily worked. 

I try to avoid the foaming stuff, but it is really good for certain tasks where gap filling is important and cosmetics can be forced or molded with tape, or ignored.

As for their CA products my opinion is that it performs like most.

  Fellow's I sure do appreciate all the help/suggestions, look forward to putting them to use..
Yesterday I found some clear glue at Lowe's, and it said DO NOT use on foam, didn't say why though, nuff said..!!

Hi All, I have a favorite pair of "reader" glasses which I am perpetually dropping and breaking the frames. I use the brown Gorilla Glue and rubber bands to hold the work together after having applied water and glue to the broken pieces. This continues to work for me without fail! Unless of course I drop the pair again and then I start all over!


Here's Looking at You!
