Well, actually, there have been many days in the shop recently. most of them have been dedicated toward Aerial Rig Mark 2, which i expect to have ready for burning man this year.

Note to self: making your own .25 x .5 x 2 inch structural steel tee section, starting with 2-inch square bar stock, takes damned near forever. I needed 18 inches of the stuff, but it isn't one of the 25 commonly available steel sections. It took roughly 15 hours in total to make the required 3 6-inch sections with holes drilled in the correct places. Next time i'll just alter the design.

That said, the central spider-hub of the new rig is coming together. After tonight, it really looks like progress is being made.



The steel tee-sections are what is joining the arms to the central hub. Much thanks goes to [livejournal.com profile] sensesurfer for access to the Big F'ing CNC Machine i used to cut out the arm sections.



The rig point is on a bearing, so we don't need to use a swivel in our rigging.





not a bad days output.

wicked :)

the circles make me thing of those metals surfaces that having lots of overlapping polished in circles - how do they do that? drill press? miller? it's neat and catches the light

I dont know what they do for those. If i were to guess, i'd say a large coarse wire-brush attachment for a hand drill, followed by a fine polish step, but skipping all of the intermediate polishing steps.

seems to be a standard hack, not sure it can be done by hand - any drift and you lose the perfect circles.

mmm.

Machine Turned finish

That finish is done by chucking a wood dowel in a drill press, putting some abrasive paste on the end, and applying it to the part. Index one dowel diameter more or less, repeat.
