    I must admit that I have been lurking for quite a while now. I have designed and redesigned a spring powered inswinger on paper time and time again; and I think I might have finally gathered the materials I need to make a pistol or wrist mounted launcher.

    I have a variation on one design mind, both utilizing a shuttle running on an aluminum rail powered by twin rat trap springs and a linear spring for under the shuttle to maintain stability.

    I will post drawings if there is any interest; and hopefully a finished project within a couple of months.

    Thanks to all of the designers I 'borrowed' design elements from. Jam

    If anyone has played Dishonored; think of Daud's wristbow....though I was designing it in my head long before I played the game.

    Welcome to the forum, Hades.
    If you have pretty good sketches of your plan you may benefit from sharing them before you get too far into the build. Or you could do like I usually do, rush right in and learn from my spectacular mistakes!
    I for one would be interested in seeing your project. Sounds like there's some common ground with a an idea I've been noodling for a while, but have been too busy to spend any time in the shop lately. I want to do a small scale reverse-draw compound using short rigid limbs with torsion springs. So yeah, show us what you got.

    Hi Gnome,
    this reminded me of an article in the Journal of Archer Antiquaries of an small torsion (sinew) powered "assassins bow" not the usual balestrino-style  but an tiny inswinger. The interesting thing is that its  foldable , spanned by a screw jack and has to be "deployed" berfore operation. Not very fast to put into action but  since these exist  they must have at least somehow worked.But only five or six were ever accounted for and are in collection.

    I dont remember where i saved it from, could even have been here or another place? If you already kow about it  excuse the double post- its not good quality pics  but thats all I have on my drive.  here it is:
    Pics are too large for readability reason  so i give you direct link:

    Page 2: http://i.imgur.com/C7IxFre.jpg

    Page 3 : http://i.imgur.com/Nj9uPJa.jpg

    not exactly copyable 1:1 to a wrist mounted version but has some interesting ideas.  If you  somehow rely on torsion , a foldable frame and rigid inswinger arms  this would overcome  the problematic of the bulkyness of a regular elastic prod for actual underarm storage.
