Why Do I Use Hide Glue? (And why not wood glue?)

I was recently asked what wood glues I use, and why I use those, so I thought the best way was to make an overly long, rambling video.

Thank you for confirming what I already "knew" and giving me some new, valuable, info. As a wannabe luthier and a scientist every little bit helps. Keep up the good work🎶

I’ve been annoyed by the PVA problem with finish like you described. I am convinced. Switching to hide glue.

Great video. I actually do a similar thing as you. I use Titebond hide glue for joinery and tabletops of darker woods. Hot hide glue from granules for maple tabletops. PVA for laminations. Hide glue is great stuff. Very strong. I like how you can steam it and take the joint apart for repairs.

@blackbirdpie217 Жыл бұрын

Titebond will come apart with heat, no water or steam needed.

Try hot hide glue for instant, no-clamp bonding. , especially useful in veneer applications and making musical instruments. Hide glue was king in the 19th century.

Thank you for the great advice and the insights into a professional woodworkers "ammunition" drawer 👍. Glue is very important and knowing the difference in drying time, colour and other properties mentioned here is not always as easy as reading the label on the back of the bottle. Your experience with different types of glue and results you have shared here are so valuable and I thank you for your time and effort making this video. Top video as always!!

Thanks for the explanation. I must try hide glue sometime. Once I glue something up, I usually leave it overnight anyway. I am gradually using more white PVA rather than Titebond. Its better.

If you use the "real" dried pearl form and mix it up before you use it, some of the "downsides" are alleviated. It's suddenly SUPER cheap, has an infinite shelf life (seriously), it dries SUPER quick, maybe a bit too quick if you don't heat your pieces/workshop... so this is a plus and a downside at the same time. But with today's heat guns etc. it's manageable. Also it dries to an even tougher, tighter bond. It also has an amazing ability when you do panel glue ups... you don't have to clamp them like a mad man. Mostly the weight of the wood will suffice, because the bone glue will "pull" on the pieces if it dries and pull them together. Bone glue is really the best glue to use for a hobbyist I think. Sure on a job... time pressure, ease of use etc. modern stuff is the way go to. If you have the time and respect for your own pieces: Use hide/bone glue.

Nice video! The demo of the finish really seals it (hah!), eh? Does the same thing happen with a water based finish? It does for the PVAs - not sure about hide glue?

One small issue - regular hide glue - not the Titebond liquid hide glue does dry pretty quickly but can be loosened with heat or water (water thins it) Regular old hide glue can be treated almost as dry in about an hour in some applications. I am not familiar with Liquid hide glue but give Thomas Johnson a look - he regularly repairs and restores laminates and furniture joints with it. With a good clamping, hide glue will set pretty quickly - at least with laminates.

Hey mate, ever used hide glue on oily woods like spotted gum? Or dense woods like Ironbark? I find that PVAs don't penetrate enough unless I wipe with acetone or metho and I wonder do you think hide glue would work better? p.s. I enjoy the calm way you present information. It's very refreshing.

@TheWoodKnight Жыл бұрын

Redgum and jarrah, yes, but nothing harder than that. I sought out a friend in the US (luthier) who uses a lot of hot hide glue about the oily wood question. His answer was "Hide glues don't rely on penetration so they are much less affected by oily or resinous woods. I generally don't worry about it when I use hide glue unless it is a _super_ critical joint" So it should work better, but an acetone wipe wouldn't hurt it at all if you were concerned.

Thanks mate! Taking the time to actually seek out an answer for me proves you're a good'n. I might have to knock up a few little boxes and try it out. Thanks again!

@1deerndingo Жыл бұрын

Thanks for that. The only issue I have is the shelf life. I'd use it in the twelve months, but I'm a bit sceptical of how old it is before I get to purchase it. I spoke to a Titebond stockist and they didn't want to stock it or even order some in because of the shelf life issue. Who do you buy yours through.

@TheWoodKnight Жыл бұрын

Timbecon and Carbatec stock it, I've purchased it from both in the past. Turns out the listed shelf life is 24 months - the same for Titebonds PVAs! - so 12 months should be fine buying from the bigger stores which tend to have more turn over. They've always come with a production date sticker on them to give some assurances.

You can always get hide crystals and mix your own. Crystals stay good forever! Lot more effort though 😁

I have never used Hide glue as a woodworker for over 30 years. I have refurbished many older pieces that were glued together with Hide glue. In most cases, the glue had failed. Over time the glue deteriorates. But, yes. I can see the advantage of using it.

@TotemoGaijin 8 ай бұрын

Seems to be why many prefer it. Better for the glue to deteriorate than for it to be strong and cause a crack or split somewhere else.

My 12-18 month old bottle of Titebond hide glue passes the “spiderweb test” but recently I’ve had glued joints fail due to re-absorption of moisture from the atmosphere. The glue had been hard for weeks but one humid day it softened and returned to a tacky state. The item was in a closed room in a shed; not sitting outside or on a deck. Is this a sign of the glue being too old or does this product simply not cope with SE QLD humidity?

@TheWoodKnight Жыл бұрын

That might be a question best directed to Titebond or the retailer as I'm not sure I'm fully qualified to answer! Moisture from the air shouldn't be anywhere near enough to reverse a hard joint unless the temperatures were >60c - sometimes to get enough moisture into a joint to reverse, people need to drill holes and inject water. Other use irons on the highest temperature/steam settings just to slightly loosen it up. No interaction with vinegar or other chemicals that could have interrupted the bond?

@ChiefTiff Жыл бұрын

No chemicals; I had removed the traces of old glue just using hot water, toothbrush and rags. Normally I don’t have anything lying around for too long but due to work commitments the item has stayed with me for weeks waiting for me to finish it off. I also found that glue residue on a plastic lid had also re-softened to the point I probably could have used it on a job… I guess I must have a dodgy batch 🙁

@TheWoodKnight Жыл бұрын

It sure sounds like it, yeah! Definitely something has contaminated it in the bottle. Old Brown Glue is supposed to be a bit more like traditional HHG, has a bit more strength and I think bit higher temperature tolerance. That might be worth a s hot?

Ayyy I also make inserts, my last one was for dead of winter do play board games often or just make them for others

@TheWoodKnight Жыл бұрын

So far I've only made inserts for myself! I used to get the excellent Folded Space inserts, but they are a little pricey and they don't have inserts for everything. Some games aren't worth $25+ for an insert if its 1/2 the price of the game! I've made inserts for Scythe, War of the Ring, Star Wars Rebellion, Dune Imperium (and it fits Ix), Great Western Trail (v1 + expansion), Calico and Descent 2E. I worked out the price of a couple of tools (FoamWerks cutters and straight edge) and materials, after 3 inserts I "broke even" vs buying from FoldedSpace

At what temperature and humidity should you start getting worried about hide glue's integrity? It can get really hot and humid on the Aussie east coast, and you know our buildings have the thermal properties of tents.

@TheWoodKnight Жыл бұрын

I haven't tested it, but IIRC "regular" hide glue needs to be heated to 140-160f/60-71c to melt properly, after being dissolved in water. PopWood did some tests, they needed 6 minutes with a hair dryer directly applied to the joint to weaken it, so I'm not sure there is any real world danger of it weakening www.popularwoodworking.com/article/hide-glue-in-liquid-form/

Hide glue doesn't weaken much with atmospheric humidity, what tends to cause failures is when the ambient RH falls to the 10-15% range. Then the glue becomes brittle, and you know the rest...

@Fixit Fingers As far as I know, Titebonds product is made with animal hide, yes. Or more specifically, I think it is likely made from gelatin left over from other industries like medicine, but still not vegan. Edit: It looks like this product was actually an April Fools by Woodworkers Journal that... they posted on the 3rd of April 2018. Original comment: "There was once a product called "Dr. Jekyll's Hyde Glue" which was meant to be purely synthetic/vegan, but I haven't been able to track down too much info for it."

Never had a problem using a Wet rag cleaning any glue as I use a really wet rag. Old timey craftsman never had the problem either. It seems only stressed out KZfaqrs do and then blame the glues instead of themselves. I always laugh at this myth. I am not having a pop at you, I just kind of feel sad for those who panic for no real reason. Honestly, give it a try, have a look at Steve Hay, I am sure you know him.

The argument also extends to guitar builders. Many modern luthiers won't use the old hide glue but mostly use Titebond original for two big reasons; When a guitar is over 40 years old the hide glue can begin to fail and necks and bridges, tops begin to separate. It crystallizes and cracks, and it can even decay or oxidize as it is an animal protein. At any stage repair guys find it extremely difficult to de-bond. Heat is the tool to soften it but when it's old it either lets go on its own, or it won't melt. PVA will de-bond with heat more easily making repairs less destructive, and it won't decay, oxidize or crystallize the way Hide glue does. Others do use hide glue simply because it's a tradition.
