110 Anarchy

This build is a treat. In my shop in the winter [santa barbara] I use a micro wave to heat aluzine epoxy right before laminating surfboards and boats. It's kinda hairy but once your time/temp chart is figured out [if you don't exotherm into oblivion] it works for me. BE CAREFUL. I really enjoy the speed up.

My resins ( and more expensive paints) live in a small cupboard, sitting on a temperature controlled heat mat, at only 7W it's not very expensive to run. Nor expensive to buy.
Once they come out to be mixed, the mixing pot sits in front of the warm air blower keeping me warm.

At my first job at an old yankee boat building shop (little to no heat in Massachusetts), the West System pumps lived in a little box that had an incandescent bulb rigged up permanently and a polyethylene curtain to keep the heat in. Worked very well. I am sure Steve has some arrangement for keeping the epoxy warm, but doing so only goes so far if the shop is cold; it certainly is not going to aid a whole lot once the resin has been spread all over the bottom of a 24’ boat in a cold shop.

that’s crazy about the microwave! In our shop our epoxy lives on top of the hot water tank

That's an interesting technique. I'm not a polymer chemist but were (are) you concerned that using a microwave can result in non-uniform heating (localized hot spots) of the epoxy which could result in curing "problems"? I suppose the proof is in the fact you're using this to build surfboard and boats but I bet you had a nice learning curve!

Alan, the microwave makes you understand the true meaning of the term hotcoat. I don't pretend to understand the complexities of epoxy reactions, so I mix them throughly a 65 f and then very briefly expose the mixture on high in the microwave. Then I rapidly spread it out on the laminate. This is dome in small batches as I go. Also it helps to use skinny stir sticks to reduce air entrapment. Be careful if you use a nonvented contrator heater because you will run out of air as the laminate cures. I have only used this nuke trick with non blushing surfboard resin [SP, RR, and Aluzine]. These epoxies are third generation products from the old WEST and Epon, resins of our misspent youth. Congratulations on a well thought out kit.

Hung the project from a scale.
WIP plus all the cut parts = 419 lbs
Pretty much on target for a 910 lb minimum weight.
Not wildly heavy or light.
We have to be careful or4 we can blow it.

Meanwhile in the frozen north....

Steve, does that tube spin with the chute or does it just offer a smooth rounded surface on which to turn?

 

[Steve Clark]

There is a roller in the bow and a second back by the bulkhead.
Chute will turn aft and then forward so it all lives forward of the cockpit.
In the top picture there you can see the little conveyor roller bearings that I got from McMaster Carr. They have stainless bearings, and I hope will work a treat.

It certainly looks like a boat from here

You should go hunt yourself some ceramic bearings. They are about 10-15% more expensive but never fail and eat salt for breakfast.
No oil, just set and forget.

( this one is approx 52mm oD, 40mm iD & 7mm thick.)

Trilogy had 3 per rudder (ahma) and took huge loads. SS ones lasted an event, we were forever replacing them.

Since we did that, have not replaced a single bearing in now, has to be 10 years in FNQ where water is pretty agresive. (Salty)

If you have issues, I can find them for you. jB

 

[Steve Clark]

Thanks, we will see how highly loaded the rollers are. I don’t think it’s anything like a rudder bearing. Intermittent load has to turn only about 20 revolutions at a whack because the kite is tiny. I’m not at all sure ball bearings are necessary.

I have about 10 of the above, and can put 4 in the post to you, if you wish. jB

Wow. I hadn't realized there is now a 110 topic on SA, as I generally skimmed right over the specialty sites, from SA directly to GA.

Ray Hunt would be pleased to see all this, and the continuing life of the 110s. My connection is strictly nostalgic, I haven't stepped into a 110 since around 1966 (?), as a high-school kid in Marblehead, I (with partial help from Dad's wallet) owned #5, built by Lawley Brothers.

And what a hot rod they were, helmed mostly by a young crowd, and a dangerous weapon to give to a bunch of teenagers in that crowded harbor (and outside in Mass Bay). You could always tell when something had gone wrong by the "110-shaped" vertical indents (or holes) in someone else's topsides, when you were trying to fetch some moored boat in that crowded harbor in windy weather, failed, then tried to bear off in a hurry to take her stern, but didn't quite make it. More typical was Race Week, where the boatyard I used to hang out (Graves) had to make some quick-turnaround repairs, and it was quite apparent who had been on Starboard ("staahbid!" in local parlance). I regularly got my ass kicked by the Doyle brothers and many others. But I learned a lot, and what a blast they were downwind on a windy day. I didn't lack for friends.

Best to you and this build and to all, and good sailing on a great boat.

@Steve Clark

Would be interested in what you would have to say over in this thread:

Canoe stern - why?

Every time I see a sailboat with a canoe stern, I wonder what motivated the designer - other then esthetics - to choose this type of stern. I mean what is there to gain, I see only drawbacks. What am I missing?

FWIW, there's a very nice article about Steve's project in the latest issue of Sailing World.
