Moldmaking tutorials

[LastSpartan]

So I watched all the Tap Plastics vids, I have a some questions.

Should I use Silicon or Urethane? (I want one durable, but not too expensive)

What should I use for casting? Cast Resin?

How do you mold a helmet, I mean the interior. Should I put Silicon/urethane inside the helmet, to have the interior? Like a three part mold?

And do I mold with the visor?

 

[Fragclone]

...you did that on paint didnt you

 

[Fragclone]

oh dont mold the visor. you cant buy one . or a helmet then take it out.

 

[LastSpartan]

Yeah, but if I mold without the visor, I will have about 1 inch to cut...

And Yes, MS Paint ^^

 

[Fragclone]

lol. true but...hm... that would e hard. but still werk is needed to make the armor

 

[Adam]

do not do a box mold, do a brush on mold for the helmet. Use silicon, it is more expensive, but urethane molds only work well with cement/plaster etc.

Mold it with urethane plastic, maybe task 15

 

[LastSpartan]

ok, thanks Adam.

And how much Silicon should I buy? 1 gallon? (I'm not familliar with gallons :$ops: )

And approximately, how much it costs to make a Helmet mold?

 

[Adam]

1 gallon will easily make a helmet for you

You'll need to get a gallon of plastipaste too, for the support shell. you can do the helmet in 1 piece, and the support shell in two pieces.

To make the mold it will be about $250 (not including the original pattern of the helmet you (hopefully) made)

and each cast will cost you about ... gosh, $30 or so...

BUT

You will do at least one or two that you will throw away, so don't be surprised, ANNNNNND if you're going to be spending $300 on a mold, make sure you buy a video telling you how to make it first, you'll be better off that way.

there should be a tutorial here on how to make moulds, like the helmet is confusing to me.

 

[corpseguy]

making a solid mold is pointless and a waste of money and materials.

check out youtube for Silicone molds.

theres a handful of ways of doing it.
