Building A Floating Arm Trebuchet

I took off!

First "proof" to show that even with little knowledge of knitting machine can do something, here is the first chore: to knit a hat with board to roll. Repeating the calculations with other measures you can do it in all sizes and if you feel you want to change the wool every time (better if you always do a number of revolutions, so the change would seem to have the wool from the same perte), you can do it too colored stripes. Just pull the wool processing from the cart and insert the new color, taking the working normally.
