Tail Boom:
Easton Arrows (archers' arrows, think Robin Hood) model 2213 xx75 or XX78 (xx78 is a harder aluminum but the xx75 works great and is harder than OEM shaft)
...The first number 22,is the od. in 64th of an inch -- 22/64 = .343 inch.
...Second number is wall thickness in thousands of an inch,in our case we want 13 .013 inch
...Thus .343 minus wall .026 = .317 or 8mm. The xx is arrow length and 75 or whatever is the hardness of the metal.
Arrows should be around $6 each and you should be able to get two booms from one arrow. Reportedly available from WalMart even.
Cut 14 and 1/4 inches in length.
To assemble the shaft in the boom: Basically you use a tiny drop of ca to adhere the center bearing to the shaft then slide it in as an assembly and then inserting the outer bearings, dimpling them in.
If necessary, you can used ca on one end of the tail drive shaft to adhere the gear but left the other one (octagon end) un'c.a.d. You probably shouldn't use any CA at all if not necessary.
