Here's the HD inserts curing in the rudder blank:
I'm experimenting with polyurethane glue here for the first time. I can see it has some definite advantages, especially the foaming/space-filling ability.
Here's me wrapping the rudder insert with carbon fiber:
(Yeah, I grew a winter beard - it's a lot grayer than the last time I had one. My wife doesn't like it though; I may have to trade its removal for a new power tool or something. :))
All finished with the carbon wrap, but before peel ply:
Wrapping the insert was easier than I expected. I coated the insert with bog before I started to wrap it, this seemed to help the carbon to "stick" to it. I also put two full turns of peel ply around it, followed by plastic, followed by duct tape in several places.
This morning after I unwrapped the insert (not much leverage for yanking on the peelply...had to use pliers to get a grip) I was very pleased with how the carbon stayed nice and tight around the insert. Here's the unwrapped insert sitting next to its home-to-be in the rudder blank:
Last, I used Grant's trick of using part of the scrap foam from the slot cutout as a spacer, to get the insert centered within the blank. I bogged the insert into place rather than use the poly glue:
Next steps on the rudder will be cutting out templates for the foil sections, then shaping.
