trebuchet specs

the day started off with myself picking up sunni and going to king lumber to get 2x4's, we got 4 12' long ones. we then ran over to savings hardware to get wood screws and some other hardware. when we got back to my cave, we started with work. ripping down the 2x4's and making the final choices on the plans. we decided to go with the base being 2' wide and 8' long. the fulcrum point is 3' high and the supports are in the middle of the base with 2 added supports on each stand. for the fulcrum we used a 1.5 inch dowel rod. the main beam is a total of 6' long, the counter weight is about 1' from the fulcrum. and the sling is about 3' long. all in all it will throw a half brick over 50' and over 70' in the air. pictures to follow.
