I built one today, using Kaboom1's method. Stopped the bolt channels short of the joints. 3 pieces one, 5ft and two, 4 ft. For pegs I used 1 inch dowel with screw inserts for 3/8 inch carriage bolts. ( counter bored and epoxied ) I use the weight method for tension. Thus the contraption at far end. Should make up to 11 ft tapers.
Don't think I lost much in the connection areas. It stacks up to take up less room in my area.

Markings are 1 ft and 6 inches. probably want a tape measure attached.

Left end is a dremel tool and hair braider.





Thanks guys for all the great ideas.
