I have just recently learned what not to do on fiberglass hull, do not use a drill bit that is too big.
Although I will be able to finish the limber hole with in the scribing lines, there was a lot of separating of the laminated layers. This is my first travel into glassed hulls. All my prior subs have been plastic. What a different game this is! Here I tried three holes with a larger bit. Not happy with what was going on I went for a much smaller hole. I will try my coping saw on this to see if it will cut out the area O.K. If not, I will put in a few more small drill holes inside the limber hole. No matter what I end up doing there will be a need for filing to finish.
To add to the conversation, what do you do to remove fibers that stick out? Do I use an X-Acto knife and cut the hairs?
