Hi Everyone, I've started learning the basics of home resin casting, working with Smooth-On silicon mould rubber and polymer resins. Fairly happy with the results so far, but have been having issues with air bubbles on undercuts marring many of my finished casts. So, I've ordered a pressure chamber in hopes of reducing this problem. If anyone out there has experience using one with these products, I'd love to hear your thoughts! (I'd also love to hear any suggestions on other products that might work well for this purpose.) I'm doing primarily 28mm minis at the moment. Thanks! |

A vibrating table might help. I got a used one that came from a dental lab. I don't see many resin cast 28mm figures out there. Even GW has problems with their Finecast figure line. I would assume that they pressure inject their molds to get them to work? Sorry, no experience with a pressure chamber

I have an Edwards vacuum unit (chamber and vacuum pump)for de-gassing silicon and resin. A pressure chamber should do a great job of getting rid of your bubble problem. |

Indeed it does! I just did my first cast yestereve after preparing some moulds in the pressure chamber prior to that, and I'm quite happy with the results. I filled my tank to about 55 psi, maintained the pressure for an hour or so and then let it bleed off slowly and that seemed to work really well. I'm definitely excited by the possibilities for creating a home miniatures line. |

Pressurized Paint pot, used for painting cars. You can pick them up at harbor freight. Simply fill your mold, pop inside, and pressurize. |

As a matter of fact, I did get mine at Harbor Freight. |
