Hi Jeff,
I fit korts loosely first, then fit shafts, again just tacked in with a dab of superglue, then check everything lines up before applying resin. It's difficult, because you need to line korts up with each other. On my Svitzer Maltby hull I then did final fit of shafts after korts fitted. You don't have much clearance if you use MMM korts and Prop Shop props. Hope this helps, regards Andy
