    First topic message reminder :

    There are a bunch of products on the market using levers and cranks as well as other contraptions for lifting or loading of various loads. Some crossbows today use one or another form of spanning mechanism and I would like to open a discussion on the design of such starting with the muddy backs and butts of the first crossbowmen and how they became cleaner and cleaner as our favorite weapon and it's accessories evolved.

    Many of you have probably already seen this video, but it wouldn't hurt to show it just once more.


    I'm planning on building my second crossbow with a built in spanning lever, but more about it later...there is so much more to discuss...

    Found this great website that has lots of info...might need a translator thou, but judging from the pictures it's definitely worth a closer look....
