Wood Glue recommendations ?

West info.

Not any easy solution to get right,
High chance of allergic reaction if safety precations not adhered to.
You have to mix the resin in precise measurements wet both side of the joint then make the filler paste up and apply it to the epoxy primed joint.

Having said all the above I have used West Systems for years.
And sold a lot of it to trade and retail customers.

Hi Stephen

Aerodux 500, and its hardener Aerodux 501 (and Aerolite 306) is still available from LAS Aerospace in the UK: https://www.lasaero.com/products/article/M02GOFJDH Think it may have been renamed Prefere 4050 for the resin & Preference 5750 (the latter is the hardener).

If shipping is an issue to Canada, either in the nature of the product or cost, see what your local amateur built aircraft folk use if you want an adhesive used in wooden aircraft construction: https://www.eaa.org/eaa/news-and-publica...r-contacts or folk who restore antique aircraft with wooden wings which can be light aircraft with steel tube fuselages (E.g. Piper Cub monoplanes and Tiger Moth biplanes), WW1 replica aircraft to larger aircraft such as Hawker Hurricanes and Mosquitos, e.g. https://www.warplane.com/aircraft.aspx

Such old school adhesives may still be in use by some wooden boatbuilders too (those not using expoxy, perhaps on vintage speedboats/sailing boats) as well as for specialist building construction.

Cheers
Mike

Slighty off topic, but within the 'zone' I have recently repaired some slightly rotten and splitting wood in the frame of the Cabriolet where the rear 3/4 of the hood is pinned to. I used this:

Having ground out and removed all the damged wood, I replaced it with this 'paste' and have been able to pin the hood back in place to great effect. The only other option would have been to replace the whole piece with new wood, which would have been a hugely invasive piece of work...

I looked at quite a few different adhesives when building my Marine Tourer and went for a polyurethane expanding foam type . I purchased one from Tool Station, having used one called Joiners Mate on previous work. The one I eventually went for was this one. It was ( or it maybe just me) a little messy if too much applied but has done a great job.

In theory PVA creeps under load, and as such is not suitable for what I'll call "serious loads" like the laminated roof of a swimming pool.  HOWEVER I've used it for laminated ply for furniture and its not moved in a decade.  Its also not waterproof in the sense of using it for something unpainted below the waterline of a boat.  HOWEVER if its painted or inside a car it doesn't get soaked.  There's also the modern miracle of "yellow glues" which really are waterproof, in the sense that they're used on boats and garden furniture.

The reason to "take a chance" on PVA (and they're not certified for bridges and aircraft...) is that they're so easy to use, and as such you're much less likely to make a mistake.  They also clean up easily, both the tools and squeeze out.

For myself I went that way after developing an allergy to the polyurethane glues I was using. The way that works is you're fine the first few times and then you nearly die.

An interesting comment here as to heat - over 180 deg F.   It doesn't come apart but some loss of strength.

Some don't like the dark glue line the 3 can produce.  Here's a warning on that, and reassurance as to what 2 will put up when outdoors.

I use Gorilla Glue and have found it easy to use and very strong.

I’ve always been under the impression, perhaps mistakenly, that there is only one manufacturer of polyester resins and hardeners  in the UK, namely Scott-Bader and so proprietary brands are in effect packaging companies and label printers who devise their own filler materials…and profit margins!

[dickie65]

Duncan,
I am afraid you might be wrong.
I think Scott Bader have resins Manufactured abroad.
We have had great difficulty getting some products from Scott Bader over the last couple of years due to raw material shortages.
The project we were working on had to have GL approved materials so we were pretty stuck !!! ( Bad Joke )

Pva glue is fine if the joints are very well made with no gaps. there is a water resistant version.
Gaps can be filled with a sawdust filled glue paste though. ( Traditional Bodge )

Ah well, things move on. Way back in the late 1970s a pal was working in production there when they were a common ownership company (his passport showed his profession as "Company Director") and they actually did make the resins there then. He stuck it out for a couple of years but the permanent all-pervasive smell did for him! He's a Horticultural Specialist now and much happier and healthier.
