Glued up an all zircote glass long bow. And when I checked it using the push pull method the belly glass came right off. I could peel it off like tape.

What is the push pull method??

Just realized I read this wrong. And push pull is like the stringing method. But i didn't have a string on it. I heard someone call it that once. Idk know the actual proper term for it.

Think you are referring to "floor tillering".

By chance did you mistake and glue the shinny side,?

I use a hard brush like this

Ok yeah I guess it would be floor tillering. I was just getting a feel of its weight. And I'm pretty sure I cleaned it with acetone but I may have missed it. I'm nearly sure I glued the rough side down. But I'm prone to mistakes. I'll check later and kick myself in the butt if I messed that one up!

Everyone here has made their share of mistakes! Unfortunately it is a big part of how we learn.

Wouldn't be fun if there wasn't a challenge and mistakes. But I hope one of these days it gets a little easier ha

I keep looking at the pic of the delam, did you flex that before side tapering? That might put a lot more stress at fades with full width limb.

Not saying that caused it , just wondering...

I did. But I don't think it was that. It was instant and started at tip end. I bet I could've peeled the glass off like a band aid m before flexing if I would've noticed. I'll get a better picture of what's left on the veneer side.

Ok just wondered

Stuff like that drives me nuts (more nuts than already)

Susquehannariverarcher · May 15, 2024, 08:12:45 PM

Scuffed it all up with some 40 grit, glued it up, put it back in the form/box. Guess we'll see if it can be salvaged.

I know Chad did it and hunted with it! Hope it works!!

I always wipe down with acetone and haven't had issues with glass peeling off. I do put the lams and glass in the bow oven for 10 minutes or so after wiping them down to make sure the acetone has evaporated. Best practice is to follow the instructions from smooth-on for this product. Here's a link to the full instruction sheets. Hint: They recommend wiping all surfaces with acetone after sanding with 120 grit.

Thanks bird bow I'll give that a read!

Pulled it off the press just now. Seemed like it worked, at least for now.

kennym · May 17, 2024, 12:17:09 PM

Hoping so!!

Susquehannariverarcher · May 17, 2024, 12:20:27 PM

Any idea what causes these little imperfections? They seem to be between the glass and veneer. This on the back of the bow not the glass I just reglued. Haven't pulled the tape off to check the belly yet.

Kirkll · May 17, 2024, 02:48:03 PM

looks like air bubbles to me....

Smguinnip · May 17, 2024, 02:57:38 PM

are you applying the glue to both mating surfaces-{glass & lamination}? I will usually get more squeeze out than, maybe not enough glue?

Susquehannariverarcher · May 17, 2024, 03:32:38 PM

Kirk of they were air bubbles would they go all the way to edge of the limb and leave visible little air holes in the glue? If so I don't have that.

I am applying to both surfaces. This picture is after glueing just one layer on. When I pull my bows out of the press I can hardly see them, they look like they're covered in stalactites worthy of NatGeo.
