Yeah, I figured the aluminum tubes would be lighter, stronger, and more elegant than threaded rod.
I may end up hiring my mom for the sewing part too so it doesn't turn out all wierd looking

I'm having trouble with the handle bar end of the tiller for the steering. Supposedly the 3/4" emt should fit over most 1" steering head set things (that part that originally fits into the top of the fork and expands). The emt is .040" or so too small so I will have to do some work to fit that.
