I have been building the galley box 2

using cascamite for the first time since I built a boat at school

I have to say that it is wonderful stuff

easier to use than epoxy and really sticks wood to wood - without the need for too much pressure

thinking about duck punt 2 could I use it with fibre-glass tape instead of epoxy

Personally I have never got along all that well with Cascamite .. probably because I have not left the joints clamped up for long enough.

At school we used Aerolite 306 and I still much prefer that to Cascamite. It still needs to be clamped up for a good while though, esp in a cold garage.

I think if I were to be doing any woodwork now I would look at some of the more modern polyurethane glues. Very impressed with "Gorilla glue" when I saw someone using it on a rubbing strake repair.


Interesting idea to use Cascamite and glass tape on joints. I have found glasstape and polyester resin quite satisfactory.
I have a Mirror dinghy , a child's Prout Puffin, a canoe and my little tender all made that way.

I like being able to use water to clear up drips

you can mix just the right amount up

no acetone to bother with

cascamite does not seem to care about temperature

Mostly true but I think you will find it takes longer to reach full strength at lower temperatures. Also I believe takes longer with hardwoods that with soft.
 
Just remember from way back...... when you were still in short trousers I expect ...."Cascover sheathing"

Cascophen, the resorcinol glue equivalent of Cascamite, was used for sheathing with Nylon cloth. Cascamite will work too apparently but the resorcinol glue is more water proof.

Nylon tape and Cascamite might be the way forward rather than glass tape.

the development of resorcinol glue was what enabled the WW2 Mosquito aircraft to be built. The Germans tried wooden aircraft but did not have good enough glue so theirs fell apart!

The Resorcinol glue from the Aerolite stable is Aerodux. Aerolite and Aerodux are still both used in building wooden light aircraft. Aerolite is urea-formaldehyde. Aerodux is stronger and (even) more water resistant but slower setting and more temperature sensitive.
I'm fairly sure the Mosquito was built with Aerolite (Wikipedia also thinks so) - didn't resorcinol glues come post war? Before Aerolite, casein glue was the norm in aircraft construction and that did fall apart with damp. A few years ago I rebuilt a French light a/c built in 1963 and a lot of that was still casein glue - and definitely unsafe! It ends up like soft milk curd. The fuselage was Resorcinol glue (they called it Bakelite which is something different here!) and was fine.

Probably right I was relying on memory.
 
I've been trying to remember the name cascamite for 16 years since I was at school and built a guitar using it! Thanks you so much, that's one less thing to worry about :D
 
Fancy using Cascamite and Aerolite at school!! How high-tech.
Back in my day, we used animal glue, kept permamently simmering in a water jacketed pot. Gave the woodwork room a distinctive aroma.
I've still got a coffee-table glued up with this stuff, though it wasn't very good for model boats, as a pal discovered.
 
You were lucky you had a pot! We only had our bare hands and used casein glue from old grocery bags. Wouldn't even have known what a coffe table is. Rusty tin drums it was back then, oh how I dreamed of being able to have one of those!
 
To get back to the point, I seem to remember that cascamite (and aerolite) were quite brittle certainly compared with epoxy. I woudn't have thought it was that suitable and it might not dissolve out the binder used with the glass and wet it properly.
 
Too Brittle

Totally agree.
Don't do it Dylan and in any case it would work out very expensive. Take a leaf out of Dynamite Paysons book and use Polyester Resin.
He just used it with the same fillers as you would use with epoxy and of course it is much much cheaper - just don't use it to glue!

I dont think the glass tape that Dylan would be using for epoxy contains a binder. I am not suggesting however that it would be suitable to use with Cascamite

+1 for polyester. It's the cheapest solution and it's a tried and tested method. If cost is no object then epoxy but it's over-design IMO.
I would not use Cascamite
