    What do people make of this design? Strengths, weaknesses?

    I like the longer draw, and the compact dims.

    Here is one example, the Scorpyd...

    This is a great design, even with pretty cheap materials I achieved good efficiency with my prototype (https://thearbalistguild.forumotion.com/t774-compound-project). Same arrow speed with a 35# draw weight, as a modern recurve bow drawing 10 pounds more. The main weakness of these reverse crossbows is that you need a cocking device even for relatively low poundages, due to the sharp string angle. The Scorpyd is definitely not the most easy to cock.

    MRobin, I like your design.

    I am thinking of using Power-Tuff from http://www.binghamprojects.com for the limbs.

    If a person was going to borrow something akin to the Scorpyd design for a home build, with a draw weight in the range of 160lbs or so, would a cast aluminum riser be strong enough? I understand there are a lot of variables in casting, just wondering if this is a viable idea.
