In 2000 we decided to take a two prong attack to our siege craft. We
simultaneously started building both a gigantic Ballista, and
a centripetal human powered machine.
Mista Ballista was our long term plan and the centripetal machine was used
in the 2000 Punkin Chunk and made more appearances in 2001, 2004, and 2005.
For more on engineering a centripetal catapult, see the
Centripetal engineering page.
In 2000 we built and tested the machine. Our drive system and trigger
were a bit flakey, but we threw almost 100 feet. Huzzah!
In 2001 we enhanced the machine with a new throwing pouch and trigger.
We also added a cool new bike platform.
In 2004 we made enhancements that allowed simplified things to great
effect at the 2004 Punkin Chunk.

Pumpkin Putter : 2001 Enhancements
|
We built the Pumpkin Putter in 2000.
After critical failure during last years 2000 punkin chunk
we decided that the putter needed an upgrade for the 2001 punkin chunk. This
page describes our upgrade path. Our longer term goal is to build
Mista Ballista, using the putter as
an interim machine.

Pumpkin Putter : 2004 Enhancements
|
In 2004, Team Tormentum got a call from Don Young of the "Junkyard Spinner" team with
an interest in creating a "Human Powered Centripetal" division. Junkyard spinner was
lonely since we had retired the 'putter in preference to Mista Ballista. There was
a plan for a second spinning machine. All they needed was one more to make a new
division at the World Championship Punkin Chunk. (Notice the picture on the lower right
on the front page of that web site.)
