Thread: HELP - cheap hi-strength wood bonding

Epoxy resin is about as strong as you will get. Available from CarbaTec.

West System Epoxy Resin

Welcome to the forum. There's a wealth of information here and you might find info by searching the forum for advice on adhesives. My favorite everyday glue is WeldBond, you'll find it at Bunnings

Mind you , you'll get many recommendations and I'll stand in line but it's a glue that I've found very useful and durable. If your looking at something that is going to be exposed to a lot of weather then an epoxy is a better alternate. Araldite is a common brand but a two part epoxy is what I'd suggest - there are many names for the same thing.


Good Luck with your project

A warm welcome to the forum.

I second the use of West Systems epoxy. Just make sure you get one that is stable to sunlight if you plan to leave a wood-look finish. Not an issue if you plan to paint.

Plastibond is a filler, not an adhesive.

I support your choice of plywood but question the pine. I doubt it is going to be suffiently strong to bear the stresses of a bike. Look at woods such as beech or ash. Others may have suggestions.

Stephen,
I'm with Derek on this. Leave the pine alone, having had a look at the design, there appears to be the need for some pretty high tensile construction and you will need a tough, springy wood like spruce. If you are short on chips , try getting hold of some old pallets or packing cases from Europe or Japan ( not the crappy hardwood Aussie ones) which seem to be spruce or something like it - very tough and knotty but if you laminate it, you can negate the weak spots due to the knots. You may even find some in the waste bins of your local timberyard, it comes as packing around imported timber, usually a bit bashed but it planes up well. Smile sweetly at the yardman and he will probably give it to you.

Re epoxy glues, I haven't tried West System, but Techniglue, also available from Carbatec, is good. It's a bit thicker than West, and has gap-filling properties. Derek & Graemet are spot on about the timber. Spruce was used (and probably still is) to build wooden framed aircraft.
