Lost Wax concept gun

    I can see that so much thought has gone into this gun Tin Man, it's a real inspiration to learn how to work with CF and learn all the tricks involved! Looking forward to seeing how the handle turns out, you can already see that it will look real sexy, even without it being fitted yet! :thumbsup2:

    The handle is done, and mounted now. The aluminum tenons of the frame are a very tight fit in the stock, but I added a small 1/8" stainless pin in each just to be sure. Funny how the shapelock looks pure black in room lighting, but shows some swirls in the camera flash.



    I don't remember when it occurred to me. I was just kicking around different ways to fit a handle when the mounting surface above it wasn't flat, and there was no room beneath the trigger mech to recess the top of a typical screw mount handle. So the forward tenon (for the trigger guard) has to reach further forward to get in front of the trigger mech.


    I may re-work the grip a little. I would like the contact point at the back to be a little higher, but I found that it feels most natural for me if the contact (between the thumb and forefinger) is directly behind the center of the trigger. With my normal dive gloves, this is a very comfortable grip.

    It fires cleanly about 1/8" before the trigger hits the frame. I may grind off a little more, just to be safe, but it seems to work fine as it is now. I checked that by making a plywood model of the trigger frame to adjust the dimensions slightly before I cut it out of aluminum.

    Tin Man---Your creation is beautiful. simply beautiful sir.
    The curves in the shapelock really fits the design flow of the whole gun.
    What a piece of art :thumbsup2:
    I'm really impressed with how compact the whole gun is.
    Perhaps in one of your pictures you could use something like a dollar bill or ruler to give a good size reference.
    Thank you Tin Man :thumbsup2:

    Nice! Did you consider electrolisys between Stainless, carbon and alluminum? It can be an issue sometimes... I remember the Jomer Alluminum speargun and the Jomer "pelagic" reels.

    A bad day fishing is ALWAYS better than a good day at work.

    Is the cf you are using electrically conductive when it's encased in resin? In any case I don't think it would behave as a metal, so I don't think you would get galvanic corrosion between the carbon and the aluminum. You would get it between the aluminum handle and the ss pins, but the more noble aluminum has so much mass You would have a lot of corrosion allowance. It certainly would be no worse than fastening an aluminum handle with ss screws. I guess if you wanted to be sure you could use aluminum pins instead of the ss ones for pinning the handle.

    Oh great, now the Tin Man will be trying to figure out how to power the laser with the electrolysis!:laughing3:

    You guys really shouldn't make fun of me. It's a sickness, I tell you . . . :D


    . . . and graphite is the noble one, aluminum the active, and stainless in between. :rolleyes1:






    So, about the laser . . .

    Oh, the stories I could tell about the "sickness"....


    And you're right- more noble, less reactive! Maybe it's the 25 or so years difference in the schooling, or the CRS I'm afflicted with!! :D

    I have used Mil-spec green Zinkchromate on 356 cast handle to 7075 barrel with good results, lots
    of SS parts inside. I do hit my guns with a hose some times to reduce salt build up. I use corrosion block spray #20012 twice a year on the mech.
