Double Thickness

As per the original plans, the cockpit coamings are double the thickness of the cabin sides i.e. 18mm. I made up an exact template of very thin cheap grade ply and used this to cut the two coamings exactly to size.

They'll be laminated together in-situ to hold their shape. I've left the after ends a bit long as they'll need to be trimmed to fit the rear coaming.
