Hi... Just wondered if I am going mad or if this idea is in any way sensible...
I was considering building a hull (possibly a Submarine) plank on frame... but using all styrene card! In other words all the frames cut from say, 2mm styrene card and all the planks from say 1mm... using larger sheets where possible... is this madness?

sounds like bloody hard work!
At some point I guess there will be the use of filler required, which probably then means some backing to you 'planks'

sure its not impossible, but maybe too flexible - bearing in mind any increase in pressure on the hull underwater.

good luck!

Ha ha... you're probably right on all counts

Ok, ok... its crazy...

Yes seems crazy ..... but how much for a sheet of 2mm styrene and a tube of glue?!

Have a go Lee, you may have come up with something really good!

I've got to ask, is there a particular reason for wanting to use the specified materials in the way you're pondering?

Been there, done that!

Works well.

Doesn't sound crazy to me. The plastic may be a bit harder to work than some woods, but if solvent welded it would be very strong.
Even if it was a bit harder to build than using wood it would probably need less 'afterwork', like coating with resin, than wood.
But surely someone has done or tried it before.

Ah, Ali has posted while I wrote.

Hi Andy...
I have, for sometime been thinking of building a sub (along with half a dozen other things I haven't got round to!) And I like the idea of making the hull plank on frame but wood is not the ideal material for a sub. So I thought...same technique, different material... Depending on the design, a lot of it would be quite big pieces of styrene and not thin strips.... anyway, I just thought you all might like a laugh!!

It's perfectly feasible, You will get through quite a lot of plastic weld.

Hi Wartsilaone, That looks very good... there was me thinking I would be laughed off the forum. The other thing about using styrene is its easier to cut and shape than ply is... but... does car body filler stick as well to styrene as to wood, considering the larger areas that might have to be filled... (I know its fine for filling little cracks and irregular joins and stuff).
Have you got any more pictures of that build, a bit further on?

Arrow5 · « **Reply #14 on:** February 13, 2013, 05:16:47 pm »

Price of styrene sheet, or maybe collect a few for "plating" effect ? BTW Gazou are you organizing an event this May ( year 2013 ) ?

Snowwolflair · « **Reply #15 on:** February 13, 2013, 05:18:47 pm »

I did my forst Type 42 in 1976 that way. looked OK but when I could aford a fiberglass hull I cut the deck off and moved it over.
Slab sided models are fine but nothing with compound curves.
The exception is if you use thick gloves and heat the plasticard over a wooden former. I have seen this done where yard builders hulls were copied this way.

wartsilaone · « **Reply #16 on:** February 13, 2013, 05:19:15 pm »

Car body filler sticks just fine as long as the area you're filling dose not flex.
I suggest adding some resin to the inside of the skin before filling.

Hi, Lash.
No, I don't think it would be a crazy idea either.
Two points though.
2mm styrene is tough to cut leaving nice smooth edges.
As for sticking the layers together......thought of double sided tape? I've been banging on about this for a few years so far but I'm not sure if anyone has used it very much.
I've found it to be almost indestructable...even when boiled.
Positioning of the "strata" would need careful thought as this stuff is quicker to grab than superglue. Accurate drawings and the use of positioning pegs might do the trick. BY.

Lash151 · « **Reply #18 on:** February 13, 2013, 05:32:21 pm »

Thanks Bryan... that is a really good idea... I shall explore this further... Maybe I could cut and laminate 1mm thick frames... (although the cost is going up!)

Hi Lee ,
Look up a firm called Hinleys in sheffield I get my hip sheets from them 1300x660mm I think in all sizes 0.5mm 1mm 1.5mm 2mm 2.5mm and 2.75 mm I think all colours think last time Got some 1mm was about £7 a sheet but dont quote me as for plastic weld its about £7 a 500mlt tin but i now use solvent cleaner for pvc windows 1 lt about £5and I think its better.
Regards Howard.

Lash151 · « **Reply #20 on:** February 13, 2013, 06:41:11 pm »

Thats great, thanks Howard...
I was just trying to work out costs based on CMB... the prices from the place you describe look a lot better.
Cheers Lee

big_bri · « **Reply #21 on:** February 13, 2013, 07:11:00 pm »

The cost of styrene sheets in my neck of the woods is 1mm £6 1.5mm £7.50 and 2mm about 9quid for 4ft X 2ft sheets.
I`ve used it extensively and had no problems, I`ve found that using plasticweld on the thinner sheets tends to distort the plastic when it dries though.
It does look quite good in between frames , gives it that "starved dog" effect

Might be ok for Chant oiler hulls too

Hi Howard
I intended to be on topic. Pondering Lee's general point I thought the Chant suitable for Lee's plasticard. The link was just so anyone unsure of what a Chant hull looked like would be able to see without having to search the web. Sorry for not making that clearer.

Dave

Howard · « **Reply #24 on:** February 13, 2013, 10:47:36 pm »

No problem DaveI was just so confused by itas I could see the link with you thread but maybe what was down to me think Lee was confused by to Buy thank you for the reply and clearering it up.
Regards Howard.
