Introduction: A Working Semi-auto Mechanism, and Round Magazine

The K'nex community seems to have lost steam of late, and it's rather sad, so here's two little inventions of mine to hopefully help you all get the ball rolling again :) No need to give credit if you use my ideas, just want to see what you can all do.

    OK concept, has been done before, not much potential in the power department... but the drum mag is really cool. more pics and internals?

    The internals are really simple, it's just two gears on a yellow rod in the center with a blue rod held in place by a one slot connector, goes a little like this=

    Blue rod > ===o===
    Yellow rod ====IoI=====
    the ls represent gears. If I have some free time I'll post pictures.
    You're right about the semi auto though, it has little power potential save with round separation mechs. Never have seen it done before though link?

    i made something from the vid and i think it is almost exactly what you have, but i have a few problems with it. once you upload the pics of the internals, i'll check if i did everything correctly, and fix it/ tell you if i still have a problem. and once again, the magazine is a genius design. first one of it's kind EVER to be made and it is looking awesome for the time being. it might just be the next type of magazine.

    I'll be putting up pictures of the internals later, they'll be added on to this instructable.

    Here's the internals.


    thanks but i actually figured it out earlier. my above comment was written about2 hours before i posted it, i guess i just forgot to press the button. anyway, reda it and tell me what you think.

    The semi-auto has been done at least 3 or 4 times now. Love the round mag by the way.

    The guy above said t had been done before, but I haven't seen it, could you provide a link?

    i don't really get the diagram or your explanation, sorry. could you take it apart and post pics of internals? it would be of great help ! thanks anyway.

    Move the lols over in my diagram until their os are in line with the others and it'll make more sense, instructables deleted the extra spaces
