Thread: Which is the best glue?

Outback
Interesting post.

My views, given where I live and work are as follows
I voted for the epoxy, mainly because it has not failed me, yet!
The reason I say this is that in areas of very low humidity, timber will take up moisture very quickly (where I am, I can get timber down to 7% moisture content). We seldom get above 60% humidity on a regular basis. When we do get rain/storms (we are getting them now, yahoo!!!! ) timber soaks up moisture at a very fast rate and hence joints and the glue holding them must be able to take the stress. UF has let me down in the past due to the very brittle nature of the glue once cured (no mechanical stresses on the joints) also the item in question was in minor contact with the elements. I have never used hide glue, so I can't make any comment on it, although from my experience, it's so easy to pull apart old furniture glued with it.
Epoxy, although gap filling etc, seems to still retain a fair bit of flexability given the constrainst mentioned above.
I regularly use Selleys "Trademans PVA" and have tried "yellow glue" (not much difference?) Cost wise, I'll stay with the Selleys trade stuff. I have tried selleys duraband (polyurethene) based glue, and so far, has stood the test of time.

What's that all about?"


It's all about glueing!




Personally I cannot single one of those out as the "best" as each of them have very definate uses and I use all of them, depending on the circumstances of eventual use of project, material, joint, environment, etc, etc. On top of that I use a lot of both the thin and medium superglue as well as white PVA and yellow glue ( Titebond original etc ). Each glue job is different and I select the glue most likely to do a good job.

And I just love the delicate boquette of hide glue, Mmmmmmmmmmm (vomit vomit).
I use them all but at the moment hide is the current flavour of the month for an old table I am restoring.

I believe that UF is as good as or superior to epoxy for bent laminations that are under a lot of stress, such as my rocker's rockers. The instructions for Techniglue (an epoxy) specifically warn against using excessive clamping pressures, so presumably it would be unsuitable for bent laminations, where in some cases high clamping pressures are inevitable. I don't know whether other epoxies may be suitable, however.

I have used liquid hide glue, but find it has a problem if exposed to the high temperatures and humidity that are prevalent at times in many parts of Australia; I made a dovetailed cabinet using hide glue, and found that droplets of the glue oozed out of the joints and then re-solidified as nobbly beads on the surface of the cabinet. This probably would not be a problem if you have air-conditioning; but, before I had it installed, the temperatures in the house used to reach 40 degrees occasionally.

I did not vote in the poll, because I feel that each of the glues may be best in particular circumstances.

Rocker

I wish I had a long technical explaination of my glue choices but....

I use epoxy because even I can't stuff it up.

Rocker

I'd agree with Rocker re using epoxy for bent laminations. I think where there may be flex, such as in a chair rocker, it may be brittle and lead to separation. I used AV203 UF for the chair from hell, with no problems.
