going to try making a balist out of stainless.
but haveing a bit of truble figering out dementions. I want to keep this light so that I can use it for combat archery.
evil I know.
How thick should the plate be?
the ajustment for the torshion spring I thought to make using an O-let with a plate welded to the edge around the cercumfrance for the pin using a piece of stainless pipe. for the stock I figered to use a piece of channel. still have not found a trigger meacanisim I like but leaning to a traditional cross bow nut out of a pool ball.
it would end up looking somthing like this

Get ahold of Christophe de Friselle. He made one almost exactly like that and brought it to winter war. He had it on an x-post w/his website listed.

you dont happen to have his web page address do you?

Oddly enough, I happen to have that address.

I haven't put up a proper website yet. The original stand was one of the shire's list poles. I'm currently working on a proper stand for it. You can see a picture of it at Winter War V at http://aurora.homeip.net/gallery/2002/WWV/index.htm .
Once I have the stand finished, I'll have some new picture and a proper site with plans up. It's based on the ratio chart from "Greek and Roman Artillery" by Mansen. I made a spreadsheet to do the ratio calculations. It can be found at http://groups.yahoo.com/group/SCA-SiegeDesign/files .
