Re: I want to make a combo... huge questions


Oh boy - this is a doosie - but I think I can work out your wrinkles:

Fiberglass cloth - any grade - is called 'cloth' because it is usually woven - the strength resides in the weave.

Fiberglass mat is only a bunch of strands held together with a 'binder' - a very light glue - but the strands are not woven, therefore it has practically no strength.

Polyester and vinylester resins contain a polystyrene element - that's the stuff that's harmful to your health, and it has a very strong odour. The polystyrene element dissolves this so-called binder in the mat, turning it into a mush - forgive the terminology but it does look like and have the consistency of snot.

Epoxy resins do NOT contain a polystyrene element so they won't turn fiberglass mat to mush - the binder in the mat is not affected, due to the absence of a polystyrene element.

You can use mat with any kind of resin, but if you're counting on your mat to be dissolved - for any reason - you won't achieve that with epoxies because those resins won't affect the binder in the mat.

If you wanted to use mat with epoxy resin, the best thing to do is to get the thinnest mat available to you. If you can only get standard thickness or thicker, you can 'peel' mat and get very light thin pieces.
The lighter you get your mat, the easier it will be to work with, especially since the epoxy resin isn't dissolving the binder and all those little strands are staying put.

Re: I want to make a combo... huge questions


Quick question, would anyone be able to help give me an estimate on how many square yards it takes to make a mask? I found a deal at home depot in fiberglass cloth that comes 9sq/ft. Would this be a good start or would more be better?

Re: I want to make a combo... huge questions


It's probably 6 oz cloth from HD. about .[sign in to see URL]" thick so to get to about .125" thick your looking at 14-16 layers of cloth, (without matt involved). a key consideration for me is size of the sheets of cloth I will cut. a good starting point has been around 20" x 20 inch square. this gives me full head coverage, but I have a smaller head. so you may want to take a sheet and lay it over the plug mark and then measure. yes larger sheets are better than small sheets that barely cover. You'll probably need to buy several packages from home depot. You may want to look online for bulk. I typically buy about 9 oz (.[sign in to see URL]" thick)cloth 50 inch wide. To get to approx. .125 inch thickness I need 12 layers, this may be 12 sheets 16.5 in x 18in = 2 yards at 50 in width or 12 layers at larger sizes which could be 4-5 yards at 50 in width.

Ok, and I appologize, granted I started this thread a while ago I still have some questions...

At any rate, in this youtube clip, Matt from promasque talks about using special resins that perform well under low temps and high impacts. Now I'm not looking for any specific brands... but I'm curious, what are some things I could look for when trying to buy some resins? Like is there something on the brand or do most brands advertise about being able to perform better in certain conditions? I appologize but I'm a complete idiot with these types of things.

The established companies can special-order the products they need directly from labs.
In your case, you'd need to talk to some reps at composite materials suppliers who will guide you to the best choice. Keep in mind that it's one thing to know about this resin or that resin, but it isn't directly available in your area you're not going to be able to get any unless you pay to have it shipped, and sometimes these products cost extra due to added insurance towards shipping toxic products.

A composites materials rep might be able to set you up with product samples for you to try out before you make a final buying decision.

Re: I want to make a combo... huge questions


I hope GreatSave31 got his mask done. A lot of helpful info here!

My first mask will be a full mask, Parent or Lindbergh-esque.

I read here on this post that non-hardening clay is best.

Would the stuff that special effects guys use for Hollywood movies be good? It says it's reusable.
It's called Monster Clay

Here is their description:

5lb Tub
Sulfur Free
Oil/Wax Based
High Plasticity
Comes in Oven-Safe Container
Used by creature designers and monster makers across the globe, Monster Clay Premium Grade Modeling Clay is a re-usable professional oil/wax based sculpting medium featuring a super smooth, low tack, low melting temperature formulation. Monster clay is non-toxic and sulfur free, can be used with platinum silicone molding compounds, and can be re-used and re-melted indefinitely. Much like taffy, Monster Clay exhibits a unique elastic quality when warm. Monster clay melts easily to a pourable consistency and is great for making copies of life casts where changes are needed. Each 5lb tub of Monster Clay Premium Grade Modeling Clay is individually packaged in a convenient, oven-safe container. What's more, Monster Clay has a lower density than average oil based clay, which means that in every tub of Monster Clay you get roughly 25% more clay per pound without the added cost.

Thanks for your time

Cheers!

Re: I want to make a combo... huge questions


I used the standard non hardening sculpting clay that I pick up at a local sculpture supply store. When working with it I like to pop it into the microwave (remove the plastic wrapper ) and heat it for about a minute to make it softer and more pliable. It works great and its not expensive ( anywhere from about 3-4 dollars ) for a 4 stick block. Its not fancy or elaborate but for sculpting goalie masks its works great. It doesn't heat up / melt once you do your layup and the fiberglass starts to cure. If you are making a cage combo and if you are looking at incorporating kevlar or carbon fiber , you will want to use either epoxy resin or vinylester only because Polysester resin will not work with these materials. You can pick that up at a local fiberglass supply store. Living in Toronto I've dealt with Composites Canada, & when I've purchased in the us I've purchased from a company called Fiberglast. If you google both companies you can check out their web sites. You can also call or e-mail them with questions. In looking at their selection of cloths you will find better quality materials than what you probably find at places like HD or Canadian [sign in to see URL] this helps! Good luck with your project.

Re: I want to make a combo... huge questions


Thanks MaskGuy5 very informative info! And helps me in my next steps of obtaining fiberglass or other compounds.

The clay that you use, after your mold and then mask is made, is the clay reusable?

The Monster clay is 5ibs for $29 and is guaranteed reusable,and I hopeful that I will make a lot of mask styles HOWEVER... This Monster clay is used for Latex mask making...

Thanks

Re: I want to make a combo... huge questions


Hi LVADone,

I don't think its reusable but to be honest I've never really tried to reuse it only becauase for the cost of a fresh unused block of clay I'd just rather trash it once I pull it from the shell layup from the plug. Another reason for using fresh clay on a new mask is because I apply the PVA and spray release in order to help remove the shell from the plug so the clay itself is"contaminated" so to speak with the parting agents.

It may be reusable but in my case I'd prefer to use fresh clay.

If you are looking for mold release for clay I'd suggest the PVA as well as a spray on mold release for application over a clay plug. The PVA is a liquid so it can be brushed on and not disturb the softer clay plug. The spray release will also leave your clay plug undisturbed. You will want to apply about 2-3 coats of PVA and or spray release.

Cost wise PVA and an aerosol spray release may run about around $5 a bottle as will the spray release.

Hope this helps. MG5
