Fletching Jig (explain more)

Ha, the dreaded 'Explain More' box has been tricked!
A comment saying which bit needs explaining would be helpful, but in the absence of that, I'll assume that more details of the fletching jig are required.
The pics are pretty self explanatory.
The clever bit of the feather holding clip is the two short screws which protrude through the lower plate. The screw tips are pointed and locate in two small holes in the upper plate. This performs three functions.
It locates the upper plate in line with the lower, it allows the upper plate to hinge open and closed by a small amount to grip the flight and it also creates a small gap between the two plates about the thickness of the flight so that as the two plates shut it grip the flight along it's edge near the vane. The two plates are sprung together using the spring portion from a Bulldog clip, the sort of clip used to hold papers together available from any stationers.
If you want to make a similar jig, hardboard would probably be OK in place of the aluminium.

There are two rectangular holes in the lower plate, but these are pointless, originally I bent down two tabs from the holes to hook on a rubber band which held the clip onto the rest of the jig, but it was more trouble than it was worth.
