While you're building, ya may as well knock up a bomber seat.http://www.hotrod.com/how-to/additional-how-to/1407-making-a-bomber-seat/Nice work, you're really getting it done!
I would look for an old metal tractor seat. They really are comfortable. http://denver.craigslist.org/grd/5018820216.htmlA pair of titanium/magnesium soled boots would be awesome and probably scare the bejesus out of all onlookers.Don't forget your Gwar mask.
