Rib Templates Complete
9/11/2005

Before routering, remember it helps to cut out the surplus material with a jigsaw, this saves extra work on the router bit.

The rib templates are now complete. A word of warning... the blue prints supplied do not correlate with the measurements. ie. the length of the ribs on the blue prints are about 7/16  longer than the stated measurement! This means that the stations along the rib and the position of the spar apertures are also off. When marking my cutouts on the kinko copied prints for the rib templates, I followed the actual measurements on the plans, as opposed to the 'print'.

Creating these templates has probably taken me around 9 hours of labour - probably the same / similar amount of time would go into building jigs for the trussed rib approach. The difference now of course, is that instead of building one trussed rib per evening, I can produce one rib in about 3 minutes. Next I will be examining how to make the aileron templates...

I suppose I need to get that damn expensive birch ply ordered from Aircraft Spruce'...


With the surplus gone. Routering is a case of adjusting the depth until finished.
