Greg, actualy my background is in primitive archery flightshooting, going for world record distances. I have set a couple of records here. I was asked to build a giant bow for the discovery channel on a Doing Da vinci series catapult and it got me interested in the siege machines which are used...
Spaceman, my biggest challenge here is to efficiently as possible use a very large weight to propel a very light projectile. The projectile will be about 1/5000 of the potential energy. This is close to a dryfire so keeping the virtual mass of the machine low is the biggest challenge. I am using...
You did partialy answer the question and thank you for the reply. What I am building is a cross beween a centrifical machine and a standard trebuchet. One of the challeges of this sport is t try and reinvent the wheel so to speak and my particular facination is with efficiency as opposed to...
I will try and cut to the chase here. My recent hobby involoves variations of catapults and trebuchets. I am finding a need for some physics in rotional mass type situations. I have no background in math beyond basic arithmatic but I have always been pretty good with math logic in a general...
