    hang some cardboard into the middle of the piece to create a small space to make the mold more pliable. the cardboard does NOT touch the part.

    i messed up the outer cast, this is by far the biggest single piece i have done. burned through 1 gallon of silicone already. i will probably never turn a profit on casting these. more to come after i get another gallon.

    as a prototype it is a success, as a usable part it is a failure. for the very first test cast on a huge part it is actually quite good. the next one MIGHT be usable.

    Thank you for posting all of this up. I'm not in a "spend money on the bike" mode right now, but I appreciate the write up and the DIY craftsmanship. It's always a pleasure to learn something new.

    there are a few ways, a vacuum pump and chamber would be great. i do not have one for this stuff so i will be doing a 2 step heating trick that usually offers good results. i might have to make some adjustments to the mold also to help let the air out. the prototype in the pic was a straight poor with no de-gassing at all, it was to test and make sure the mold will work, and i did a color test at the same time. my previous mold making experience is from small figurines for game pieces, so this thing has a bit of a learning curve for me. still i expect to have a usable piece soon. i was at least very happy with the color.

    also the plan is to run off the batch until i am out of resin, there might be 10 total good pieces. they will go for sale on this board and then ebay for whatever is left. there does NOT seem to be a huge amount of interest in these so that should more than cover the current group.

    if you would like a CLEAR one you might make your self known. at this time i am only planning on doing the smoked color that is shown.

    if for some reason you would like a different color (like blue, green, purple, yellow, etc, i would need to know that very soon too)

    looks pretty good so far. I had this on my mind a while back, but spoke with a bloke that did some stuff in Melbourne and the investment was way more than I was prepared to stump up, that was mostly the degassing pump, so I'll be very interested to see how well your alternative method turns out, good luck

    so the alternative method, that i use in solid colored pieces, worked good. but not great. i was able to get about 75% of the bubbles out, and nearly 0 surface bubbles. if this was a game piece, it would be fine. for a lens it is still not acceptable. on to plan....F or maybe G now.

    i have come this far so i shall be seeing this trough.

    +++ for your determination. Be sure to check my xenon retrofit if you're into lighting.

    bought a bloody F****** 2 stage vacuum pump. going to have to mod the mold a little more and build a vacuum chamber to do the next test cast. need to find a pressure cooker to build into my casting chamber. on the bright side i should be able to do some serious resin casting in the future. its going to be a couple weeks before i have anything new to report as the pump has to ship and i have to assemble some more stuff. hold tight, I'LL BE BACK!

    crushed an aluminum pot with my vacuum pump.
    i did get my mold modified and i am set up for another test cast as soon as i get something to hold the vacuum, i am going to go look at pressure cookers this week.

    I am looking at your project with interest.
    Do you have any idea what a finished piece might cost?

    i am planning on the bolt on lens costing 75$ shipped to the U.S.

    cross the pond shipping will be at cost + 75$ for the lens.

    this is not a complete housing, this is not "HID or LED included" this is a simple lens that replaces the red OEM lens. what you do under that is on you. the lens will be cast and cured in a dyed resin and will be about OEM in strength. cure time is honestly about 7 days before they will be installable so i will probably runn off a batch and then sell them as opposed to selling on a 1 by one basis.

    hoping to have the vacuum chamber completed this month and then sales available by feb.

    I understand that you only make the lens.
    Can you show us more pictures of the production? I find it interesting.
    Do you have an idea of how to disassemble the original taillight lens?
