Step one

Posted on Updated on

The first step in building the fin is to create the rear spar. It is made from one rs-532 and two rs-5 glued into the profile of a ‘C’

I placed two rs-5 between the rs-5 that make up the spar, they function as a spacer. Clamped this assembly together.



Covered the rs-5 with thin coat of epoxy the whole length.

Placed the rs-532 on top and stapled it to the rs-5.



Rear fin spar completed.


Well not quite completed. Need to remove the staples once the glue dries.
