One big improvement I saw with this float half over the first one, is that all of the bulkheads fit with near-millimetric precision. I am 100% convinced that this is due to the improved plank-to-keel foam fitting. It was very cool seeing these parts fit so well. Only wish I could have done so well on the first float half.
I also made myself a cheap little fillet tool out of a small piece of plastic. At first I was going to make a handle for it, then said hell with it, it's going to get all gunked up anyway. Amazing what a few square inches of plastic can do; the resulting fillets were great: smoother and sized more consistent than the ones I did by hand before. One weirdness that happened while doing the fillets, is that some of the fillets turned yellow on me (obviously due to heat generated during curing, although I didn't think the putty was that close to 'kicking'). The fillets that experienced this did not appear to malform (no catastrophic meltdowns), but it certainly looks a bit odd. I'm hoping that this is not a fatal condition, but I sent a question to S3's support line about it just in case.
By the way, did I mention how awesome Thalco rubber squeegees are for laminating? I used one for the first time on this float half. A bit expensive, but you can easily drag them around the cloth and get the excess resin out.
Another pic of tape cutting central:
And here is the chainplate pad laminated to the hull side:
I tried to be extra careful with the chainplate pad...I'd hate to be sailing along some day and see that chainplate come ripping out of the float deck. (Do other builders have daytime nightmares like this?) Also, careful readers will note that since the chainplate pad went into this float half, that means this is going to be the starboard inner half. I know I said my first half was going to be the starboard inner, but changed my mind earlier this week when I couldn't wait to unmold the first float half.
[Edit: System Three responded to my query already (on a weekend, no less!) with the following response:
Hot epoxy will turn yellowish in color. So long as it is not brown you are fine.
Phew, good thing -- I'd hate to have all that work wasted.]
