As the title sugests I have a large slab of brass, ie the deck, which I need to attach to a big lump of plastic; the Hull.
As the contact area between the two parts is only a coulpe of millimetre around the deck/hull and a few cross braces, I need an adhesive that can bind to both, is stronge and a little flexible to avoid cracking due to expansion differences between the two rather differsnt materials.

Being water-proof is not an issue, as the only place this ship is sailing is on the side-board.

Bath sealant??

Epoxy resin or supaglue.

Well worth a look.
With the contact surfaces abraded, you just have to ensure that the item to be fixed is actually in the right place, because it ain't going anywhere else after.

Copydex ?

What kind of working time does that have? I dont want to get to the end of the line, only to find that ots dried up where I started. I would guess that " once around the deck" and across the cross braces is a total lenght of a good meter at least!

Maybe an epoxy would be better as it will give a longer working time?

Sorry Ian - didn't scroll up enough!

DJ Parkins will be thrilled to hear the photo etch called a "large slab of brass"....

Dave.

Zap-a-Gap superglue. I recomend the green which is medium but you might find the thinner yellow better for etch work. I've used both and so far the results are still together after 15 years an counting.

Hi Ian, I have also got most of the corvette fittings from DJ Parkins including the deck fitting kit but I have only built the winch, rope reels, 20mm Oerlikon Guns and 2 Pdr. Pom-Pom Gun, I thought of using PVA to join the deck to the hull if I ever gain the skills to do it justice!

You are probably right there, but hey! He does actually have a good sence of humor.
Besides that its easier to write huge slab of brass than; new foc's'le deck made from photoetched 0.6mm brass sheet. 

Think I'll go the epoxy rute. belive that Robbe does one that can handle a bit of flexing.

PVA no good for metal or plastic.

I can thoroughly recommend Holdtite adhesives acrylic bonder. Its a two part epoxy (pink and a green tube) supplied in a equal discharge cartridge. Smells terrible when first mixed but drys odourless. Bonds brass to abs, glass fibre, or any plastic permanently. I use to purchase it from Scoonie Hobbies when they came to the Leamington show but they have informed me they cannot send it mail order due to its toxic content. hopefully I can still obtain some locally from a builders suppliers! Dam good stuff.

How did scoonie Hobbies manage to get it in stock ??? Somebody must have posted it to them.

Probably that new invention the delivery lorry

Exactly the point i was making,, it is still toxic and somebody else must still handle it.

Yes, but not the post office. Unless you are shipping in large quantities, courier etc is disproportionally expensive. Whatever you think of the post office, it is a relatively inexpensive way of moving stuff around the country but they don't handle items classed as 'dangerous goods'.
