Another new piece in the works

So I'm having some fun time with the engineering.  It's a difficult thing to make some large scale works, especially when thinking about transportation (small truck bed and no trailer yet).  All of my larger pieces so far can be put together with cold connections.  I enjoy the aspect of building and rebuilding pieces when I take them apart and put them back together.  It's as if the work is regenerating or being re-born in a new space or location.  The current fun is my new idea. It's based off a truss system I was thinking about when I was reading about timber framing.

The maquette above, when finished, should stand around 15ft tall.  It's at a good scale, 1" to 1'. I first mapped out all the angles and lengths.  Then built a 3-d model in Google Sketchup (shown below).

After the Sketchup model confirmed my measurements and angles from my maquette I order my beautiful steel square tube; 3in 11gauge wall. 

I primed the tube to prevent rust and it was easier to prime in full lengths.  I cut my angles and sizes and now I'm just waiting on a weekend to bust out the welding and recutting for assembling and disassembling the piece for transport.

My idea for the assemble/disassemble ability is to use a 2/34"OD 3/4" wall round tube inserted in the square tube with plug welds and cold-connections to hold it all together.  I'm hoping it works well and I figure I might as well paint the thing red since it's already big. Why not, right?

Stay tuned for more to come.
