    Nick, you should print some of those up. I think they are worth playing with.

    Mark, are you willing to post a step file or other non stl file? I was looking at the pictures and had some thoughts worth trying.

    Sure. If another file format is better or different settings for the step file are needed just let me know. The file contains two versions - the latest version and a prior version that has the subtract shapes still separate.

    Epic. I will be printing some to test. I have a Suffren that will serve nicely as a test bed.

    I'm thinking the Constitution might be a good test bed too. Just a little nudge...

    Heh, yeah, I liked it so much that I had to make one. :) I do need to adjust the piston a bit to make it shoot right, but other than that she's ready to go.

    Awesome job, Mark!

    Now I just need to make a shorter, twin version of this for my Shimakaze rear turrets...

    Out of curiosity, about how long did this take to print?

    Shorter is a problem, but one I'm working on. I think I'm going to have to go back to a round magazine to make it shorter or to make a 75 round version.

    The BIC takes me 2 hours and 55 minutes to print. The dual magazine for my Dunkerque takes just under 4 hours to print. But the Dunkerque gun is an Arizona style so it has no pistons.

    Cool!! nice design!
    Its been around 16 years ago But i played around with a design like this the coil in the magazine always had feed issues. This is before 3D printing as i made resin molds.
    Maybe your 3D printed version will work better. I have since been working on a new complete cannon but intend for it to be machined and serviceable

    Nice work!

    It took several tries get a magazine that would pass BBs easily. For example, the drop in the corners turned out to be critical to make the design work. The 3D printer is helpful to test multiple prototypes and once you have it working you can transfer the design to metal for machining.

    I can do that. You cover the cost for yours by assembling and outfitting some for me? :D

    Bravo! While I still like brass for some of our parts, this is the future. My son in law and I have been working on similar stuff, so I am aware of the issues. this looks quite good.

    yeah. but how do you machine the internal channel of the magazine. I suspect this will always have to be 3D printed

    Got the piston problem sorted out. This gun works really well, I was impressed. Thanks again, Mark for sharing your excellent work. :)
