Post subject:  Clean up bridge glue squeeze?
I have a very small amount of glue squeeze that was hidden under my StewMac bridge caul when I glued on my bridge. I used Titebond. Gluing was done 36 hours ago.

Looking for the best way go clean this up without damaging Joe White's finish.

thanks

You can use acetone Paul. I try to get as close to the top with a chisel and then clean up with Acetone. Don't apply pressure as you may dent the top.

Consider HHG next time...especially for the bridge. Excess hardened HHG can easily be removed by softening with warm water and simply wiping or carefully scraping away.

Thanks Peter - I'll give that a try.

Hi Paul, get yourself a bottle of this stuff www.de-gluegoo.com works awesome on all water-based glues. Just cover the glue for 15+ minutes and wipe away.

Acetone will clean glue off a Polyester finish fine. Here's what I do to keep the glue cleaning to a minimum.

Just run a sharp knife around the bridge when you're done, and the squeeze out will stay on the tape. I use hot hide glue, but I suspect Titebond will clean up the same way.

you can simply use white vinegar it's a lot less nasty and dissolves titebond without damaging finishes.

In fact I believe that the de-glue goo mentioned above is just vinegar (at least it smells like it) suspended in a gel, which makes it a bit easier to use.

I second the de-glue goo recommendation. It's good to have around the shop too.

Don't use acetone! That well melt lacquer and won't do a thing to the Titebond. Use a damp rag and wipe carefully with your fingertip.

My finish is a Joe White Poly - not Lacquer.

Definitely vinegar and don't use Titebond for the bridge.

You can't just throw a "don't" out there without a reason.

"cool factor"

that settles it - I need HHG - I need all the cool factor I can get!

Also, of all the places to use HHG, the bridge is maybe the easiest. You can easily heat the bridge to a good temp, put on the glue and have plenty of time to place and clamp before it cools.

Now there's a "duh" moment for me. Thanks Waddy!

Sorry about that Paul. It's what Todd said, Titebond creeps. Hide glue and fish glue don't creep.

Hope this isn't changing the subject too much.....but from what Randy just said, is using fish glue for bridges as good as HHG? I ask because I have fish glue and I'm used to using it.....but I don't have HHG nor am I setup to use it (at least not setup right now). I had planned to use fish glue if it is a good alternative to HHG.

So where should I go to get some HHG - and is there something I should get or not get?

LMI have what I need? I need to order some other items from them anyway.

Yes, theoretically fish glue is more moisture sensitive than hide, but quite honestly you would literally have to take a very long shower with your guitar for that joint to fail. Truly, getting a fish glue joint apart with water is very difficult and time consuming. Ask me how I know. A lot of builders including myself are using it for many aspects of guitar construction, including gluing plates to rims.

Actually, I believe a Fish Glue joint is harder to get loose than a HHG joint. I'll never forget taking the back off my #2. It's the worst mess I'd like to think about, and took me a couple of hours of inserting hot, very wet pallet knives and putty knives. Once started, HHG joints seem to release a little easier.

I like fish glue too but I have heard of 2 instances where it has let go when exposed to very high humidity situations. Dave White posted one example on another forum of a guitar left in an abnormally high humidity apartment and a local guy here had a repaired mandolin top pop off after a very humid summer week in Massachusetts. Both of those are outside "normal" circumstances and involved prolonged exposure to a very high humidity environment but it has made me more nervous about the fish glue. Many people have done tests of short blasts of high humidity and it seems to pass those fine but the longer it is exposed apparently the weaker it gets. I will add I have not done a test myself to verify this, I am only relating others experience. In both cases the hide glue joints of these guitars remained sound. I do still use it in certain situations but between the two if I can use hide glue I choose that first.

Interesting Burton. As a comparison, I wonder how many have ever heard of an HHG glued bridge failing? Has HHG never failed......or will any glue likely have a few joints fail if not executed properly?
Author:  muthrs [ Wed Mar 10, 2010 12:01 pm ]
Post subject:  Re: Clean up bridge glue squeeze?
Hi Burton, hard to draw any conclusions from two cases. Joints could have been badly prepared or old glue could have been used. I'm sure there are many more cases of HHG failing, not because it is inferior, but because it is much more in use. Just a matter of statistics. Doesn't Romanillos use fish glue in Spain?
