Just used some yesterday to glue some binding. It has dried hard as glass, not the slightest bit rubbery.
Like I said - Your mileage may vary.

I just saw this in the new Lee Valley flyer.http://www.leevalley.com/en/wood/page.a ... 42965&ap=1 Would the 192g Bloom strength be adequate for lutherie? I know that bottled liquid hide glue is pretty much frowned upon for guitar building. Might this be an exception? Alex |

I am also interested in this - 192 g strength seems like what is commonly in use - is that correct ? The set time is a little long, 24 to 48 hours. I would like to use a glue where I do not have to have a hot pot - and also be able to do rub joints, and sucks a joint together. I understand that fish glue is also good, but the open time may be too long for rub joints ? Is that correct ? Sorry if off original topic - |

Fish glue will do rub joints just fine, but with the clamp time being longer than Hide I would wait longer before counting on full strength. |

I do not recommend Old Brown Glue. My experiments with it found that it stays pretty rubbery when dried, vs the glass hardness of HHG without urea in it. The guy who makes and sells it, is a Matquetry guy, and he uses it for that. Might be great for that, but not for guitars, in my opinion. |

Quote: My experiments with it found that it stays pretty rubbery when dried, vs the glass hardness of HHG without urea in it. Hmmm... I've used this stuff pretty extensively, and haven't noticed that being an issue. I use it for gluing tops and backs, kerffed lining, and sometimes for wood binding. Of course, I use regular HHG for pretty much everything else, excepting the fretboard to neck glue-up, where I use epoxy. It is true, it takes longer to cure completely. Also, when it is "puddled up" it will take forever to cure, but I have found it to cure very close to the same hardness of unadulterated HHG, when used to glue a good fitting joint. I kind freaked out the first time I used it, and after taking off the clamps, discovered that drips were still soft. Really soft! But an examination of the joint, and what little squeeze-out remained, plus a couple of glue up tests convinced me it was OK... Of course, one's mileage may vary! Waddy, could you have received a defective batch? -Mark |

I got some OBG that had just been mix. New. I tested it and it never got hard. Put a blob of OBG on a hard surface. Wait a week or a month or six months and press it with your nail and then see if you still want to continue using it after that. Cheers. |

My results, exactly, Elman. I let some dry in a puddle, waited a week, peeled it up and it still was bendable like a piece of rubber. After a month, it was still bendable. I threw the rest out. |

I've used it for binding before and my experience was like Marks, dried very hard. Has anyone thought of mixing in a little OBG or maybe even fish glue with HHG to extend the working time of the HHG just a schoosh? |
