Custom 24in. MUni Specs?

I was wondering if anybody has a custom built 24in. MUni frame;and if i could get the specifications off of you. Like:

Tube Size/Shape?
Frame Width?(inside frame and outside frame, to fit 3" tire)
Lenght Of Tube from Seatclamp To the Crown of Frame?
Lengh of tube From bottom of crown to top of bearing holders?
Also, could i just buy two sets of these?http://www.unicycle.com/shopping/shopexd.asp?id=635
Weld on set to frame, and use the other?

If you can’t tell, im trying to make a muni frame.Any help is apreciated.
