Glue Migrating Out Of My Edges? Any Idea Why?

[The Grizzly]

Weird problem here. Since it's started getting warm here, I decided to do a test on a sheath to see how well this beeswax/paraffin/nfo mix works when the sheath is subjected to heat...in my truck for example.

Using a sheath I completed a few weeks ago, I put the sheath in my console and checked on it about a week later. Here's what I've noticed:

-Wax mixture stayed in the leather, no problems with that = happy

-My glue joint on the edge of the sheath has a couple spots where the glue migrated out through the burnished edge. What would cause this? Imagine a pb&j sandwich that gets squeezed too hard. I'm using the blue tube Barge cement.

-The other problem, is that it looks like my welt shrank inward just a hair making my glass smooth edge look weird.

I'm confused to the cause of these 2 problems. Could it have been the wax mixture that worked down into the leather causing it?

Any ideas would be great!

Temperature changes from being in the console have an affect on the stuff you use.

What type of glue did you use.?

It sounds like your useing rubber cement by the color of the tube. Get the red and yellow barge cement.

Or even Masters Contac Cement...........

Don't use rubber cement, use Master or Duall 88. But I suspect that is not the only problem. The finish might have soaked into the outer layers and not into the welt, then the heating in the truck and the rubber cement might have allowed the two outer layers to expand a little more than the welt. I'm just guessing here. Anyway, use a good contact cement to start, if it happens again, refinish the edge after whatever happens, happens. I doubt the contact cement will squish out.

Hmmm, the cement I have is the tubes they sell at Hobby Lobby.

It's a blue, black and white tube that says:

"Original Barge All Purpose Cement" it's the toulene (sp?) formula.

Is this not the correct cement to be using?

What about using DAP weldwood, I've been hearing people talk of using it with great results.

I've got and tried some Weldwood this winter and it didn't stick real good. But after reading on the can it said that the temptuer needed to be above what i can't remember but my shop was colder than that. But i am going to give it another try sense it has warmed up. For all of my glue i put it in a small coke bottle. A plastic one and drill a hole in the cap, then use a piece of trimed sheep skin to put the glue on with. Then use the sheep skin piece to cover the hole.

Hi Griz,

It sounds like the right stuff, I don't use the stuff in the tube as it thickens up too much. I like glues like Master where you add thinner to bring it back to fairly thin. You have to let contact dry before sticking it together, it shouldn't be gloppy, it should have a shine when it is ready and be a little tacky, 15 minutes usually, stick it together, give it a little hammering and it should be there forever.

I use Weldwood and am happy with it. Apply to both surfaces, but not sloppy with excess, just coat the surfaces so both have a sticky layer to bond together.
