shops

Well, depending on the size of your hobby shop, they may or may not. I'm you're talking about submarine kits, they probably some. As for genereal hobby materials (styrene, epoxy, glues, paint, RTV, etc), they'll most likely have. However, I doubt you'll find WTCs though.

RTV: room-temperature vulcanizing can refer to silicone, which is good for sealing, drying rubbery at room temperature. Styrene is a plastic, sold at the hobby shop in sheet form, for forming structures and surfaces. Epoxy is used as a glue but I'm not sure of its range of applications.
Subs in the hobby shop...here in Texas...good luck. Maybe a few models, I'd guess.
By the way--at Hobby Lobby, models and r/c are a tiny part of what that store sells, the models are generally one aisle tucked away in the back while the home decor, fabrics, and crafts are center-stage at HL. Yours may or may not have r/c gear.
But if you're lucky enough to have a Hobby Town nearby-- those stores are small, but r/c and models nearly fill those little stores.

thanks A LOT guys
and one more thing could you mold Styrene into any thing? like for example make the front part (dome) of a scarch built PVC submarine look at the pic

Yes......... but you'd need a vacuum-forming machine. Here's how this process works: the machine heats the styrene plastic (usually in sheet form) up to a level were it is easily flexible. Next, a vacuum is applied under the styrene sheet over a mold of the piece you want to get, the heated styrene is sucked onto the mold by the vacuum, forming its shape. This process is relatively cheap compared to other methods (for example, kits such as the Dumas Akula in your picture above and the Robbe U-47 were made this way). You could also get a hold of these machines here:

thanks alot. See wut i'm to get at is that i'm making a pvc submarine and all i need next is to make the fornt and back part of the sub and i don't have any to mold out of or a least I don't think i do.
and one more thing is could you tell me how much these things cost more or less? and wut do you need to make a mold?

Well, I'm never vacuum-formed anything in my life, but the mold doesn't need to be something heat resistant as the plastic sheet is already preheated before pulling over the mold. I imagine something like wood would work nicely as a mold. As for cost, it can be anything from $100 to about ten times that, depending on the area of the vaccum-forming surface.

Unless you going to be churning out a few hulls, there no point in vacforming as you need make a mould to sart with. Are you going to be glassing your hull or are you going for an all plastic boat? If its the latter then you may as well vacuum pull the tube part of the hull as well, either all in one go, if its small wnough for you machine or in 2 parts and glue them together. This way you dont have worry about gluing and contouring the styrene nose cone to the PVC tube. You should be able to find shops that will vacuum form for you if you provide the moulds.

yea syrene looks a little to compicated and ezpensive is there some kind of mold clay or stuff that you can mold the nose cone into?
or have any other ideas to make this instead?

Styrene isn't complicated at all, it's one of the easiest plastics to work with. Molds are not built from styrene. Instead, you can always use wood or foam to form the nose cone and fiberglass the part using epoxy.
#13
Would fiberglass be applied as viscous liquid or gel? Enough to form the nose cone in the mold with one pouring, or many layers?
I wonder if modeling clay would be a suitable mold--haven't worked with fiberglass.

I've heard of something called "liquid fiberglass" but I'm not sure if it works well. As far as I know, the classic fiberglassing technique involves applying resin on top of fiberglass cloth or tape, as many layers as needed until the sub hull is thick enough.
