Absurd Weight

This guy could be our un-doing. We filled the thing with sand, with tthe intent of adding water to make it even heavier. That’s probably going to be a little over the top.
It’s about 600 pounds right now. That’s a lot of weight, maybe too much. We’re looking into plating up the throwing arm around where we bored the axle-hole through to avoid splintering at the thin points (anybody have some plate and carbide bits we can borrow ? )Anyhow our initial figures are indicating we could chuck a 10 pound object…. well, I don’t really want to let the world know how bad we are at math… lets just say plenty far.
