Re: [bolger] Micro Trawler help needed
> squeeze in the epoxy glueI recommend a paper pastry cone to squeeze out a bead of
thickened epoxy into tight places.

I did much the same as Bob on my Microtrawler using 1/2" doug fir plywood, which means what at first looks impossible can be done!
Attach one side panel to the stem, then later the second side panel to the stem which then makes a big awkward assembly to handle, so assemble it on, or very near the hull bottom. Use a spanish windlass as suggested, to pull the sides in close enough together that it will rest on the hull bottom near the bow, use some mini sawhorses or somesuch to hold the rear portion of the side panels up to the hull bottom level. Draw it together a small bit at a time. As you close the rear together the bow area will bend out enough to fit the bottom shape near the bow..
Then align all the bulkhead (bulkheads are already attached to the bottom, right?) and side panels to the marked lines (you did mark those bulkhead locations on the inner sides?) as well as the side to bottom joints.
I used 1.25" drywall screws to hold the whole thing together, using oversized holes on the side panels, then with all aligned I removed them one at a time and replaced them with 2" drywall screws that I only screwed in partway which allowed the sides to pull away from the bulkheads enough to let me squeeze in the epoxy glue before cinching up tight again without worry about alignment.
If I (or we) haven't answered your problem, let us know....

at the stern using the aforementioned Spanish windlass. You have to do both
sides at once. It actually went pretty easy this way. When everything was
aligned, I backed the drywall screws out just enough to spread the epoxy between
the panels and the stem, then tighten them again.

Peter's Spanish windlass will be a big help.
If needed, you can also cover the panels with towels and pour a kettle
of boiling water on every 10 miutes for an hour to loosen them up a
bit. Then, once pulled in with the ropes, anchor them with temporarty
screws, and leave them to dry thoroughly before any epoxy bonding
attempt.

I am building the Micro Trawler, and need some advice. I have the box
keel done, the sides on and the sponsons on the keel. How do you get
those #@$% sides around the sponsons? I am not having any success
getting the sides of the sponsons to make the bend. I made all the
parts out of 1/2inch, so they are a little stiff.
Thanks, Stephen
