    making a clean right angle cut in a fiberglass hull

    Once again I want to tap into the vast experience represented on this forum.

    I have a need to make a right angle cut in a fiberglass hull where I must save and eventually use both pieces, i.e., the hull AND the piece I cut out. In the past I'd use a Dremel tool with a circular saw with the finest kerf to make a start hole and then work a hand saw into the hole to finish the cut.

    Surely, (I know - don't call you Shirley) there's a better way - isn't there?

    Case in point - the youtube video of Bob's build of a Thor Seawolf where he cut a square piece out of the upper hull in order to mount the forward dive planes onto the lower hull. Great idea, Bob, I'm going to steal that one.

      Make two parallel lines where you want to part the structure. Space between them 1/16". Use a carbide cut-off disc or diamond wheel to make the cut -- it's kurff will be a bit less than 1/16". Block sand each piece down to the line. Build up the edge of one piece with plastic strip stock or a CA-baking soda slurry. Done.

          David,

          Once again, you have justified your existence. I hadn't considered cutting out a bigger kerf and then building it back up with strip stock. Good idea.

          Feel free to continue breathing my air.

              That is a funny statement. I am laughing,. You have a great sense of humor, thank you!
              If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                          No. simply almost no time to play. Between the flood recovery and production work, no time. The rate of sales with Nautilus Drydocks is much higher than before. Mike did the heavy lifting by organizing the forum, finding sources of supply, and getting the word out. Bob is the best guy to take over the good work Mike did and take it all on a more directed, streamlined direction.
