Do I really need a pressure pot and vacuum chamber for eye making?

I was wondering if a vacuum chamber is really necessary and if I couldn’t high pour the resin into an eye mold, because I just have a mold for one eye and it would take forever to always run to the university to get access to the chamber. 
And do I really need a pressure pot can’t the eye dry by itself because I don’t have one and it seems very complicated. It would be so much easier to do it all at home without those tools... 
I would use eye white from motion picture fx for the core and epoxacast for the clear coat

  • Hi Maximilian,

    Here's some advice from our Epoxy Eyeball course instructor John Cherevka. Hope it helps! - Matt

    "It's highly recommended to use the vacuum chamber and pressure pot. You can try other techniques, but you may have rejects. Small bubbles tend to find others and make large ones. You can try pouring the EpoxAcast and letting it dwell for an hour. Then pop or scrape the bubbles off before closing the mold."
  • Thanks Matt! Over the day I was able to get in touch with John too :) but thank you so much for the effort and help!

  • Hey Max,

    Glad to hear you were able to connect with John. Please be sure to share your results on the Forums. We'd love to see how your eyes turn out!

  • absolutely, I’ll just have to wait for the kits and materials. long way from LA to Austria! The eyes will be part of phone cases!

    have a Good day!
  • Hi Max, I made the jump and bought a pressure pot and a vacuum chamber to make eyes and John's excellent molds. The only thing I don't have is an oven for the cure. I looked at an electric smoker but they are hard to get over here in the UK, but Germany seems fond of them so you might be able to get one locally.

    Failing that, I tested an electric blanket! £20 from Amzn. I was able to wrap the pressure pot in it, cover everything with a sleeping bag and maintained the right temperature for 8 hrs. To paraphrase @Matt Winston during the Epoxy eye lesson "They don't make stuff for special effects, we have to use things made for other purposes"

    Here's a pic of it warming up. Good luck with your eyes!




  • Wow thanks for your answer Steve,
    i do have excess to a vacuum chamber at the university but I only had one mold so only for one pour at the time. I upgraded this now to four molds. I will see if o will make it without a pressure pot and oven and without running to the university for a chamber. But if not I will most likely also get those things.
    I didn’t know that an oven was really necessary.’but Might get one too! Interesting technique with the electronic blanket! Thanks for your effort to answer!

    Hey Steve,
    What an ingenious use of the electric blanket!! Thanks for sharing your tips with Max. :)
    Best,
    Matt
  • Thanks @Matt Winston. Frank Zappa was right...

    @Maximilian Schmid the heat is only really needed to speed up the cure of the particular epoxy John recommends. So if you can wait a few days between castings you shouldn't need to heat cure.

    I will let you know how the blanket performs as I'm casting cores at the weekend (although we're experiencing a heat wave here in the UK so I might just leave the pot in my car for a day!)

    Great solution with the electric blanket, I would never have thought of that!

  • Very cool I’m still waiting for my kits to arrive and will gonna try my no pressure pot try...

    thanks for the help!

  • Hi @Maximilian Schmid , I demoulded two eyes today after clear-coating and leaving in the pressure pot for 24hrs, (the wait is the killer). I didn't use my blanket this time because 24hrs in the standard cure time in "usual" temparatures.

    I can happily say that following the JC (John Cherevka, not the other guy) method, I came out a winner with no visible air bubbles.

    I'll be making more so if you use instagram, look for me as @deadoptic and we can bounce off each others experiences.

    Here's pics of them right out of the mould before a wipe and clean.




  • Very cool I followed you there:) I’m so excited when I will try it out myself but my kits and supplies didn’t arrive by now. 
  • Hey Steve, Thanks for sharing your excellent results!! Great to see John's method working so well for you. 
  • Thank you @Matt Winston, I owe it all to you, the artists and your wonderful school, it's as simple as that.

    Wow, those are some great looking eyes!  The pressure pot sure does wonders to make those bubbles shrink way down.
