I love doing terrain and homemade pices, But i tend to be on a very tight budgjet so i would rly love to learn how to do moulds and make copy's out of the few barrels i have.
Soooooh where can i get ahold of the stuff i need? i'v looked around but im not sure what it is im looking for :p
name of product and where i can get ahold of it for a decent price

cheers

Lego for starters!

yeah the lego part is not a problem :p but dont know what brand'n place i can buy the moulding clay/whatever its called that you pour into the mould :p sofar my only exsperiance with this stuff is the Clone a willy i gave my gf :p

Yup. Legos and more legos. Aside from that you'll need molding clay rubber to rubber mold release, resin mold release, rtv and of course the two part resin. Micromark is all i've ever used and i'm very happy with it. I've done everything from guard arms to whole buildings with it. Best of luck and send pics!

Which moulding rubber and clay you use depends a lot on what the various companies are willing to ship to your part of the world.


I use a platinum-cured silicone for resin casting (you CAN use a tin-cured one, but if you want to do clear parts, they don't work as well) and a mid-range polyurethane resin (2-part) for casting.

You will probably want to invest in a vacuum chamber to pull air out of your resin at it sets or you'll have more holes and obliterated detail than Finecast.

I started here:
http://www.amazon.co.uk/Oyumaru-Reusable-Modelling-Compound-Clear/dp/B0058GYGAQ/ref=sr_1_1?ie=UTF8&qid=1398411691&sr=8-1&keywords=oyumaru

Cheap, inexpensive, re-usable mold. Simply put in boiling water (well not boiling, but boil water and put in a cup then put this stuff in ), wait till soft, take it out, press your item into it. wait 10 mins, take your item out and push in your clay, or GS or whatever.

What to put in the Oyumaru:
http://www.amazon.co.uk/Milliput-Standard-Yellow-Grey-113-4g-Pack/dp/B001OBBTMW/ref=sr_1_1?ie=UTF8&qid=1398411806&sr=8-1&keywords=milliput
and

Mix the milliput and GS in a 50:50 mix, or any other ratio, more GS will make it more flexible and rubbery, more milliput will make it more brittle but sandable. a 50:50 mix is a good mix for best of both worlds.

I think about trying out this

The OOMOO 30 / Smoothcast 300-System was recomended by another user here on dakka who made a nice tut on casting your own buildings.

There is a product called instamold

I swear by it, you put it in boiling water, cast the mold, put it in the freezer and 10 mins later its rock hard.

you can do 2 part molds as well.

and when all is done, you can re-boil and re-mold the instamold

as far as resin, your typical hobby/arts/craft stores usually have two part liquid resin.

grab two small measuring syringes to mix the parts equally with accuracy and you're in business

Instamold/Oyumaru is great (pretty good detail retention, reusable, easy to use, being transparent and softened by heat) for replicating small parts, but it's really meant for "casting" 2-part putties in single- or double-sided push molds. For thick items like barrels, you're better off casting in plaster, let alone a 2-part liquid casting resin. For either, you'll want to pour an RTV silicone mold.
