How about here for a start...

The reason we don't all use is because basicly it is apain in teh ---- to use

Hi New Lou-

I use hide glue when I am doing a project with enough batch gluing to warrant the bother. I like it for veneers too, but I don't yet have a vacuum press, relying on a veneer hammer instead.

For a glue pot you can use an old hot plate but it's important not to over temp the glue. Any spilled on the element will burn with the devil's own stench too.

I bought a new temperature controlled heater used to melt beautician's wax on eBay for $50.00-does a great job on hide glue.

Hide glue fits nicely into the dark side ethos, and I like it.

Once I get past my current (endless) shutter project I think I'll try it on a chest that I'm slowly making for my daughter.

Cheers
Greg

Hmmm, Greg - bit of a contradiction, here?! Or do dark-side ethics allow you to use 'high-tech' 'lectric bits as long as it's conscripted from some entirely different intent?

Just stirring - I use hide glue a lot, for at least three of the reasons Lou states above - reversibility, sticking to itself, and its non-creep properties. Have had a few nasty experiences with PVA glues, hot days and stressed joints.

And it's really much less of a PITA than you think, when you get used to it. Having some resonably-controlled means of heating is a must. It also helps to work to some sort of pattern so that glue-ups happen in batches (this often means lots of clamps, but you can never have too many clamps, can you?). By glueing in batches, I can warm up the glue 1/2 an hour ahead of time and use it quickly, rather than keeping it warm and evaporating all day. As the day goes on, you have to add a bit of water anyway, but it's not rocket-science. It's much more tolerant than some texts make out, as far as mix goes, just don't overheat it, as that really upsets proteins.

There are a lot of fine pieces of furniture still stuck together with hide glue after a couple of hundred years. There are also a lot that have come unstuck - at least partly through mis-use of the glue, but the good news is they are generally easy to repair!

I would NOT use irreversible glues like Araldite on fine cabinetry - well, perhaps for some joints like table tops that (you hope) should never fail or need re-working for any reason. If it survives a generation or two, it's almost certainly going to need a few running repairs. (If there is anyone left around in two generations time that can actually do the work ), they will not be impressed by having to try to fix failed epoxy joints!

My 2c worth....
Cheers,

Restorers swear by hide glue as it keeps them in work fixing failed hide glue bonds.

Personally I'd question the use of hide glue for anything other than veneers. For veneers, the ability to fail is outweighed by the ability to make it fail on demand and the fact that it bonds to itself. This argument is only required due to the fragile nature of veneers and the need to repair with as much of the veneer undisturbed as possible.

Other than that, it is a vastly inferior glue to many other modern products... i.e. PVAC

That said, it is of significance in maintaining authenticity in restored pieces, and in the making of exact replicias of old furniture.

There are many valid reasons that it lost popularity when good alternatives came onto the market.

There are also many good references in the bookshelves of most libraries, not hard to get your hands on some literature. the Ubeaut book covers it as well.

Not sure why this kind of attitude seems to prevail in regards to contemporary/modern views of Hot Hide Glues.

Personally I'm in the opposite camp and think that quality hot hide glue is far superior to many modern products. I tend to believe that were all victums of great marketing and use of certain products for convienence sake ie: Modern glues?

Ever had to try and fix or sepatarate cured joins using modern PVA's....................Not much fun!

Proper use of Hide glues has resulted in Joinery lasting for hundreds of years!!!.................I'm not sure what the longest lasting modern PVA join has been recorded at????

In saying this i'm simply attempting to share my interest on this one with forum members....................and won't get on my soapbox to much until I have some experience using the stuff!!! heres an extract from a recent article I have been reading from FWW MAGAZINE:

Researchers at the <st1:city><st1>Franklin</st1></st1:city> glue company (the Titebond people<o></o>>

then broke them apart using a machine to test the shear strength<o></o>

Gets you thinking........................a quality Hot Hide Glue may well represent a forgotten pinnacle in strong versatile adhesives for airloom and fine furnature!!!!

New Lou got in ahead of me, but I just can't let that one go by, Clinton, even though I strongly suspect you are just having a bit of a stir!
I'd be challenging the basic knowledge of any 'restorers' espousing that philosophy. (And a bit alarmed at their ethics!)

For starters, most joints don't fail because of the glue, per se. Properly made and applied hide glue is far stronger than wood, as are most, if not all of the 'modern' glues. And I repeat, there are many grand pieces of furniture that have held up with hide glue (and good basic joinery) for far longer than anything glued with modern glues. In fact, I'd go so far as to say, the vast majority of pieces put together with synthetic glues more than 10 years ago are already 'history'. (This is more likely due to poor materials, construction and joinery than the glue, I'll admit).

We were taught woodworking with hide glue back in the 50's and I was very glad to give it up for nice, convenient, no-stink PVA glues when they hit the market. But there are no free lunches, with the convenience, you get, at no extra charge, thermoplasticity and glue creep, which is of considerable concern in our warm climate. I have never experienced sprung joints with hide glue the way I have with PVAs. Now that may be due to poor technique on my part, I'm willing to entertain, but I have been particularly careful these last 30 years or so, since I first encountered the writings of Mr. Frid and Co. There are a few woods, and Blackwood is one of them, that seem to do unpredictable things, no matter how diligently I dry, condition and arrange boards for large panel glue-ups. One of the reasons I gave up on PVA glues just about completely, is seeing one side of a Blackwood desk open up from top to bottom a few years after glueing with the LV/Garret Wade 202 that was touted as being less susceptible to creep. I swear all of the wood was out of the same pile, and had been acclimatising for several years before use.
Getting the top and bottom carcase dovetails apart to reglue it is a job I'm avoiding as long as possible, and it would have been so much easier if I'd switched back to hide glue a few years sooner!

Avagooday,

Just a note on my experience with hide glue.

My dad's hobby is Pipe Organs and most of the old windchests are assembled with hide glue. A few years ago Dad and I were involved in rebuilding an organ for a church that had been moved into a private school for their chapel. Part of this is that we had to cut one of the old windchests in half to fit it in the new organ case (12ft off floor suspended off the wall no supports to the floor).
The hide glue seams on the inside of the windchest were perfect. Considering the the joints were basic lap joints pinned with wooden dowels and in this particular windchest there would be close to 400kg of pipes sitting on it, I think that is pretty good.
Also on the ability to dismantle the joints, we had to do that in a couple of instances. It took an hour flooding the joint with boiling water before we could safely pry the joint apart. In the middle of summer, not a very fun job.

I'll try to find some photos of the finished organ next time I go to see dad so you can see what the windchest look like.

That Franklin test that New Lou cited used (I think) their pre-mixed bottled hide glue. It is inferior to traditional heated glue.

I like hide glue for another reason too-you can add things to change the bonding rate, which can help with a complex glue-up.

Someone's going to claim that the ancients had better animals to skin, hence their superior glue. Actually, since I thought of it, that's my new position.

Good post Lou,

I've used the Titebond liquid hide glue for veneers and such, but haven't yet ventured into the arcane (to me) world of hot hide glues.

When I was a school, the woodwork shop had a double boiler in one corner of the shop for the hide glue; nobody with any open nostrils would go near the blasted thing We all had a nasty suspicion that the bandsaw was put to, ahem!, "other uses" overnight to help maintain the glue supply....

Well its great to hear that theres a few Forum members round 'the traps' that are using Hot Hide Glue. It appears that there is a general belief that Hot Hide Glue is an inferior adhesive product and a major hassle to use paricularly by those who have had little experience with its use.

This I must admit is a belief that I held myself until recently developing an interest in Hot Hide Glues and their capabilities. If you are worried about hide glue joints being weaker than PVA,you can set your mind to rest. Testing shows that, under shear stress, the wood around the joint fails before the glue line.

This is true of both adhesives. PVA (White & Yellow Glue) and hide glue bonds are usually
described with the oft used phrase, “stronger than the wood itself”
which means that neither glue will create a weak point in a properly
executed joint.Remember if your glue is stronger than your wood, why worry
about how much stronger?.

Don’t be intimidated by those who say how hard it is to mix, or how
expensive the equipment is; Be creative. In the Hobby shop craftsmans
studio or small production shop perhaps there is a case for re examining
the use of quality hot hide glues.

For my own Woodworking adventure I have decided that examining and
testing its use is an absolute must!!

Indeed it appears that there are a number of major benefits & advantages
to having Hot Hide Glue in your adhesive arsenel. PArticularly when it comes
to crafting HEIRLOOM and fine furnature pieces.

HOT HIDE GLUE...........An almost forgotten gift from THE DARK SIDE

I haven't used the stuff personally, but have been in 'shops with disgusting gluggy gluepots laying about. All I could think of is how could you get neat clean work with a setup like that! Does dried excess come off OK?
I have used Casein glue, which is poisonous apparently (or so I was warned when I got the packet), but also a natural glue, coming from milk products. I don't touch dairy products anyway, so it seemed like a fair warning. I was impressed with the stuff, did a great job.
New Lou, as much as we all detest nitpickers...its heirloom with a silent h, not airloom!! Good on you though for getting us thinking of alternatives.

Cheers,
