Trebuchet of the large variety (a work in progress), 4.28.07 update

Step 8 Further order of operations

Here's the plan for the next week or so (I'd like to hear thoughts):
(0) get wood for the base ends and make 'em
(1/2) put the small additions onto the main support as per the plans
(1) drill axle holes in main support; fix the possible alignment problem by assembling both of the main supports, putting the axle through them, leveling/squaring everything, and then drilling the bolt holes for the top piece's connection to the rest of the main support
(2) continue refining model

how are you supposed to make the arm, counterweight, and release mechanism? this thing needs to be finished. besides that, this is a very great instructable, keep up the good work.

Is that just metal on wood for the axle-throwing arm connection? Definitely overdrill the hole in the arm and pound in some pipe that fits over the throwing arm for strength and less friction. I can't tell if you've already done this from your pictures, but it definitely makes a difference in range. PLUS you can lube it.
