Hide Glue

Post by Dolds » Wed Mar 22, 2017 9:25 am

Hi All-I am using hide glue for guitar # 7 for the first time, and have 315 gram hide glue. Can I glue the bridge with this strength glue? I previously used Titebond and I am unsure whether hide glue at 315 gram strength is sufficient.cheers Paul

That's more than strong enough. I use a mixture of 315 and 150, which roughly comes out at 250 gram. You'll have slightly less open time with your 315, so keep a rather warm workshop and make sure your clamping set up is thoroughly worked out.

What michael said. That is strong, and you may struggle with the open time of it.

The commonest advice is to warm the wood before you glue it . Especially ebony .One useful lamp for this would be a small halogen table lamp . Test the heat and area on a scrap of wood first to see what is possible. Even a hot water bottle will make the job easy . Basic things like keeping the guitar still and managing the clamps can add to the streamlining process .Make sure the room is warm and avoid any drafts (draughts)(?)

Yes, try and avoid all types of draughts/drafts - getting drunk while glueing is never good, but being hauled off to join the army is far worse in my opinion.

Seriously though, a hairdryer works well.

hello Michael N

i have looking for the hide glue and most i found doesn't came with strength info.
I have looking to the axminster seller and they have pearl and liquid, the pearl i dont know what is and liquid i dont with that.

i need it not to all guitar, at least for now, i wist just for the top glue, like bracing for example.

where you advise me to buy?

i saw in Dictum (germany) but they don't say what strength is ... maybe is a for all kind of work.

other question, to maintain the glut it the hot pot i thinking in buy this http://www.wilko.com/slow-cookers/wilko ... vt/0316165

with water and the glue inside a glass jar .. is a good idea?

Buy a Lindam bottle warmer on e - b a y. Every so often they come up used for a few £££. Use a baby food jar.
The Axminster glue will probably be bone glue, which is usually around 150g strength. Madinter sell a very high clarity hide glue at 280g. You can mix the two glue types (it's all collagen) and the strength will be somewhere between the two. Alternately just use the Madinter glue.
Touchstone tonewoods sold a mix of bone and hide glue. It worked perfectly well but I haven't used it for some 10 years. Of course there is no guarantee that what they are selling now is exactly the same. It may be the same, it may not.
I have used the Liberon bone glue and although it has a relatively low gram strength it will work. I've built whole guitars with it.

They aren't all the same. I don't know about the Tommee. It's a question of whether it gets hot enough. The Lindam certainly does. One will turn up on e - b a y, just give it time.

Dictum´s hide glue granulate is 280 gram strength and high clarity. I use a 2nd hand baby warmer, Avent brand - gets more than hot enough.

Generally - gram strengths aside

( I have never seen european supplliers quoting gram strength ? How does 'gram strength' tie in to varying
amounts of water dilution ? )

Scotch - or bone - is the old glue of woodworking joints, pre pva days - its usually large round pellets. It has good open time but is a bit brittle.
Hide glue - less brittle. Varies a lot in quality from suppliers and their current stock suppliers. Good stuff looks like demerara sugar.
Dick used to sell nice hide glue ( 12 years back ) - then it went all smelly and cloudy, so I switched to Kremer. Their hide is in 'small cube' form - and is very clear and nice
Maybe 'Dictum' has better stock now - or I caught the tail end of the bin or something. I do still use it - and it sticks well - but it stinks !

Rabbit skin - nice, from good sources. Its the most flexible - but is a short open time.

Avoid at all costs the 'rabbit skin' as sold for gesso making - its ground up smelly rubbish ( Liberon etc )

I used to use rabbit skin all the time - and it was sourced from Sydney Evans in Birmingham - so my remaining stock of that is quite old - to say the least ! The rest I have was sourced from Dick ( Dictum ) - and its top quality. Don't use it much now.
