    Good idea but it will not work. The resin sets in about 2 min. The best way is to be careful when mixing or put in a degassing chamber. Or cheat! Go to ebay or a flea market and look for a Polaroid SX-70 and get the lens from it. That is what I did.
    I live in the middle of Michigan... you'd expect there to be more flea markets, but there aren't! At least, not any I've heard of...

    I found a different way to mix the resin and get a better result. I also have one kit ready if anybody would like it.

    Hey Asok, really nice job on the hollow RFs! I forgot you had this thread on making hollow RFs coz I am doing the exact same thing. I also have the lens from an old non-functional SX-70 camera that I bought for only $10 dollars. I just hope mine turns out as good as yours!

    If I can make this, just about anybody can. I am like you and did not like the RF that are out there. I just cast mine so when I break it, I just cast a new one. $10 for a SX-70 lens, WOW! Mine cost me $30 each! Great find. Also, this is my 3rd try at making a RF. So, if it takes a few times, do not worry about it.

    Have you tried a pressure pot? with a pressure gauge.
    The kind that you use a air compressor with,not the stove top kind. I use one everyday at the Dental Lab where i work. The water can be room temp.
    We use it to take out the bubbles in the dental acrylic when making small dentures or partials.

    It may eliminate your bubbles completely.
    This is one i found ebay.

    how much does a little pot like that cost, and how big a compressor do you need?

    yeah, i could google, but i don't even know enough about the tech to know if what i am reading makes sense

    Naah, I just cannot figure it out. Please tell me which is which? Just kidding, that is just great. Just like clear part of glass. Or did you just drop some water on your mold and dropped it to a freezer?
    Sweet work there!

    Hey!

    These look GREAT! If you do start offering them please consider me - Ive no RF or stalk so these could be just the ticket!

    Very impressive pics with the two side-by-side - cant wait to see the process!

    I knew that would work for ya;-)
    I'm a dental tech by trade and i work with different resins and dental acrylics all day and a pressure pot is the key to an excellent casting.
    They look awesome!

    Can you tell me roughly how much these weigh.
    I'm researching a lightwewight rangefinder 'cos my stalk is cardboard. I was originally just going to have a shell but it would be nice to have the clear part and everything else in there.

    Hey asok!

    Got my parts yesterday! WOW - just WOW!

    Beautiful casts! At some stage I must post about the first ever cast part I bought, an E11 Blastech and what a POS it was... set me up for thinking all casts required major surgery - how wrong I was!

    Absolutely beautiful RF (and MQ1) - worth twice what your charging! AND I dont know how you got it from the states to ireland so fast!

    If your EVER doing any other parts Im in Great work!

    Thank you very much!

    Dave
