how to make soundproofing

rjwood_uk · 30-10-2007

anyone know how to replicate the soundproofing used in helecopters (like you can see in this pic) i need it in 1/72 scale but in general would help.

i have been told foil can work but how would i get it to dip in at the windows? one way i was thinking would be putty but not without fear of putting too much weight into the model and straining the landing gear.

maybe padding the foil out with paper mache and mould the "dips in" by the windows with the mache and put the foil on top?

not sure. the 2nd photo shows what i mean by the bits dipping in by the windows.

I'd suggest getting some milliput, spreading it onto a sheet of thin plasticard and then maybe try to find some expanded mesh the correct size and press the mesh into the still soft putty to emboss the pattern into it?

It might work or it might be a total disaster!

i may have found a way of doing this. i will post some pictures up later.

its long, tedious and laborious but could well be worth it!!!

What about using cotton wool. Would that work. I wouldn't know exactly but i would of thought that might give the effects and details of what is shown in the photos.

Alan525, I've used that method with pretty fair success in the past. Depending on the scale you're working with, typically for 1/32 or 1/48 scale you can find some pretty good meshes. For 1/72 I would reccommend going to find a set of trashy fishnet stockings (yes, I know it's horrible.. but it works) with a fine enough mesh. Mosquito netting can sometimes also emboss for smaller scales.

Please let us know what you do rj.

I have used a modelling clay in the past called DAZ. It is pretty similar to Milliput and you can roll it into thin shets before embossing the surface with a metal grate before cutting out the window openings.

It's a cold settting clay and you have a lot of time before it starts to cure.

You can use handkerchiefs with that kind of pattern. I used this method for tank's zimmerit at 1/72nd. I found it harder to work with clay or anything else similar. Bunkerbarge, can you tell me more about this DAZ?

Use Wine bottle foil-it holds it's shape better. cheers

DAS modeling clay (see http://www.doart.co.uk/acatalog/Clays.html), (scoll down) can be rolled to a very fine thickness and hold ist' shape when it dries out, the stuff i experimented upon was a grey colour but you may be able to get different colours or change the original.

I'm sure you wil find more info from a search.

There is something which dries to the consistency of soft expanded foam, i little harder than the ceiling tiles that used to be fashionable years ago, i think it is called "Model Magic". If you can find any info it may help. Because of the consistency the material is very lightweight, about a quarter of the weight of Milliput i would guess, and the finish is resiliant, rather like rubber, (i use a piece of it as a small sanding block).

I played around with this stuff some years back and never actually used it (no need on boat models) so i just hope my memory is ok.
