    Currently working on a bullet crossbow. Pine stock with polycarbonate reinforcement, polycarb one piece thumb-trigger and adjustable sights. Prod made from Suede Saw steel cut into layered strips, something like 60 pounds at 8''. Making the double string right now, will post pics when done.

    Finished today, finally. LOTS of trial and error. Don't use softwoods for stocks unless your making a toy, learned that the hard way. I had everything setup and lashed the bow in place but that was not strong enough and the bow would actually pivot as it was shot, ruining accuracy. So, I tried to make a slot in the end and failed, breaking off the whole front of the stock, garbage wood. So I simply extended the sideplates and used them alone to replace the broken section, works wonderful.

    Bow is canted, held in place within a slot, shimmed with wood. Stacked prod setup from Suede saw steel. Adjustable rearsight and foresight. Stirrup from bent rod (not fun to make). 

    The thumb trigger had me dubious but I actually really like it. With a hard finger trigger you tend to jimmy the stock left and right which affects accuracy, but with a thumb trigger the force is applied vertically, which doesn't affect anything, leading to a very accurate shot.

    Speaking of the accuracy, it's very great. I fudged the angle when remaking the sideplates so it shoots very high, but once the sights are adjusted, it is consistently accurate, with little to no deviation; it'll shoot a hole through cardboard, and then shoot again through the same hole.

    That's in a vice setup, though. I need to work on my marksmanship haha.

    Seems like I cant post images, though. Could someone help me with that? Seems like they updated the reply system.
