[TowerTalk] Orion 2800 mast clamp redux

[Steve Bookout]

Along those lines...

I use a male/female 1 3/8 inch (?) splined shaft from agricultural 
tractors.  Tractor Supply has a shaft approx 8 inches long that has a 
male spline on one end and a female on the other. You can split it and 
use both pieces to make a good drive joint.

I would think it would be less expensive and easier to find than a truck 
part.
