I havn’t tried this yet. A friend makes wood fins and glasses them up. For the screw hole, he drills the hole larger that the screw, fills the hole with resin/glass fiber mix, then drills through the mix the correct diameter of the fin screw.
yes Mike that works … I do the same with the horizontal pin .
…you have to be SO careful doing that with the vertical screw, though , as you have SO little margin for error…one slip , and the tab is broken ( so then I end up moulding the base anyway !!)
