A baker's piping bag helps get thickened epoxy into those tight spots. When I installed my thruster tube I rounded over the edges and wrapped some glass from the hull into the tube. Didn't take much extra work. Looking good! Cheers! Rick.
Yeah, I bought a bag of 50 of those piping bags, I just really don't like using them though. They seem awkward to use. I have some empty caulking tubes I fill with thickened epoxy when I have a big job to do, and the syringes are really handy for small jobs as you can just suck the epoxy in them from the tip. The reason I decided not to glass from the tube inside to the hull; I've seen issues with flow separation on a hull with rounded edges. So I thought I might get better flow from the thruster if it was a sharp edge.
@@scottfintel8935 I find if you keep the piping bags small and use a zip time to close them they're pretty handy. Bigger jobs they're ok but can be messy. I built up a small lip on the leading edge of the thruster tube to deflect some flow around the hole but my thruster is much more forward than yours and closer to the keel so it's quite open to flow if I hadn't. I didn't fair my box keel either. I read Dave Gere's book too. With a plywood core hull I had no meat to remove. Keep goin! Cheers!
