OT- Best Rubber for Casting Parts

http://www.ares-server.com/Ares/Ares.asp?MerchantID=RET01229&Action=Catalog&Type=Product&ID=82083e

I've used this product with good results.

when the mold is completely cured (4-5 hours) you can use it to make clear or opaque resin items.

I have used Alumilite with it and it is okay but I would recommend the  resin kits by micromark as it is a lot better.

GI-1000 is the industry standard, a 10/1 mix ratio. It is available at Burman Industries (http://www.burmanfoam.com/).  Also, Smooth-On (http://www.smooth-on.com/) Mold Max series is very good. I like Mold Max 30.  Hope this helps!

Thanks MadK I appreciate the links I have saved them for future reference. I have had a lot of others recommended the smooth-on so I may go that route.

Pressure/vacuum are not required for Smooth-On's OOMOO products if you are careful to not entrain too much air when you are mixing the 2 parts of the mix.   Pour a bit of rubber over the part being molded first then spread it around with a brush or toothpick to get good coverage.   Then pour the rest of the rubber to cover.  OOMOO sets in 4 to 6 hours. See the HOW TO section of the link I provided for much more info

Thanks very much for the help,it is appreciated.

I like Smooth-On's OOMOO-30 RTV.  http://www.smooth-on.com/ It is a 2-part mix, volume:volume, so you dont' need to mess with weighing out small weights like with other materials. Smooth-on also makes several excellent resins.  My current favorite is the Smooth-Cast. While on the subject of clear resin - they can be used by the home hobbiest, but they take a long time to harden and often require a pressure pot to minimize entrained bubbles.

Does the Rubber needs a pressure pot as well? Because I do not have one and cannot afford to buy one or make one. Thanks for the link. I can hopefully read up on what products they offer.

not much of help I'm afraid but I saw the resin casting kit at my local craft shop. It was for clear resin casting kit but believe you could use for other projects as well~ Sorry can't remember the brand name...
