funny bones pt.2 - machining

Our biggest leaps forward came when my Dad (along with my younger brother), decided to give us a hand with the armatures, which has been great. He's put together an amazing jig for drilling the joints, counter sinking the holes and cutting to size, it's enabled us to put together joints efficiently and most importantly accurately.
here's some photos, if anyones interested we could probably stick a video up next time it's getting some use.


















essentially, you measure and mark your lengths using the ruler to the right then feed the brass strip down the alley in the middle, where two pieces of bike chain form a circle above the brass in order to feed the drillbit into the center-ensuring the hole is in the right place everytime.
You can then pivot the drill round 90degrees to the second alley where you feed your now drilled strip in order to countersink the holes (allowing the ball bearings to sit well in the joint).
I may stick a more detail explanation up another time but i think this'll do for now.
