63018Re: Stitch & Glue Gloucester Light Dory
- Feb 7, 2010I beleive it was Jim Michalak's second attempt at boatbuilding after a Teal back in 1986. He was put off by the effort (time??) and cost involved in the jig construction for a one off boat. He thought he could use the sides expansions and mold dimensions for the Gull as given in Payson's "Go Build Your Own Boat" and stitch one together. Payson agreed. It worked, and Michalak thought afterwards that the method might work for non-instants like Bolger's Thomaston Galley and many of Chapelle's designs. He also thought that the method might also be able to incorporate frames, chine-logs, etc, and not just be used for stitch and tape adaptations.
Amongst the good stuff on Chuck Merrell's site is his "Private Postings" page where you'll find PDFs of 9 issues and an index of "Instant Boatbuilder" to download and save. You'll find Michalak's "epistle" on building the Light Dory in an instant in Issue #7 at page 1 http://www.boatdesign.com/postings/pages/instantbb.htm
I note that for his much later plan offering of a cut down stitch-and-tape adaptation of the Bolger Light Dory that Michalak insists on the necessity of many molds to hold the sides shape. Their removal is about the last major step in the construction sequence outlined. The numerous molds are still rather cheaper and less involved I think than the jig options given by Payson for the Light Dory VI. I wonder if the outside chine-logged Light Dory V double-ender, the one Bolger thought the best performer, might go together much easier and more cheaply still if done the Michalak way?

> The big difference, if I'm not mistaken, is that the original was not intended for "instant" style construction, where the panel shapes are predefined and the location of frames or molds are indicated on the panel layouts. As such, you have to set the molds on a jig or ladder frame and spile or otherwise take the panel shapes from the setup. At this point a chine log starts to make things easier because it defines the bottom edge of the side panels. You could spring a batten to accomplish the same result if you really want to use S&G, but you'll have to get the bottom fitted and somehow attached to the sides before you can flip it over and off the jig to start taping the inside joints.
