Building Baby Dot

[Tim Marchetti]

I took advantage of some wicked unusual weather and started building my 15ft. sailing dinghy. The mold is done and the transom, stem and keelson are installed and beveled. After I rip a bazilion strips I can start have fun. To be continued...

[Duncan Gibbs]

Looking forward to the progress Tim. That's a lovely transom already!

One question though: Isn't it better to leave a bit of meat to the top of the transom that can be trimmed off once planking is completed and the hull turned over?

I don't know, is it????

[Duncan Gibbs]

I think the school of though is something along the lines of having something to clamp to so that the good stuff doesn't get damaged. This also extends to leaving the stem longer than finished, allowing for margins of error and 'eyeballed' sheerline corrections and tweaking.

I do know you've built that lovely canoe before, so maybe I'm being overly cautious. In which case... Carry on Sir!

[Tim Marchetti]

Thanks Duncan. The mold and the transom were cut with a CNC router, so hopefully there won't be any need to tweak anything. Time will tell, if I designed everything right.

rip and strip, rip and strip, rip and strip
a little every day

[Rich Jones]

Looking good! What are the strip dimensions? It'll be sheathed inside and out with glass? What are those temp fasteners holding the strips to the molds?
Curious because my next build will probably be a small strip planked sailboat.

[Oyster]

your chewing that right up, ain't you tim? to my blind eye it looks like the strips will layout nice,no cheaters. have you made provisions for the centerboard trunk in the keelson yet, or does that plunge in later. looking good.

thanks Richard, the strips are 1/2x3/4 pine. She will be glassed inside and out with 10oz. cloth. I use 1.5"#16 brads nailed thru little plywood scraps.

Thanks Royce. We've had a heat wave here and I'm feeling the presure to get her done. I will glass inside and out before I cut the slot. Then I will glass the slot too.

1/2"x3/4" sound thick to me for a boat that size. I've never built one though. I am nearing completion of my 18' canoe and the strips are only 1/4" thick. What do you think she'll weigh when she's finished?

I'm not sure what she'll weigh, but she is 6ft wide so I think the scantlings are about right

[Tim Marchetti]

80 strips down, 24+ or - to go

[johnw]

Wow, this is quick work!

[Tim Marchetti]

1-2hrs a day after work plus about 6hrs today. It's adictive, once you get going.

[Oyster]

tim,
i think i remember you using titebond 3 for glueing your strips, are you using that between the strips and keelson too?

[Tim Marchetti]

Yup, everything will be sealed in epoxy and glass( just like my freighter canoe)

[Tim Marchetti]

So close...
But I ran out of gas. The strips aren't going on as fast now that I can't just run them by. It's been a few years since I built my freighter canoe and now I'm remembering how much bloody work it was.

[Tom3]

Tim, I'm enjoying watching your design and build. Few questions. Does this mean your sons can have the CD10? Which boat gets the cherished tie off spot in Rockport Harbor? Look forward the launch. Tom Young(the old one)

Hey old Tom Young. Thanks for checking in. You're welcome to stop by and check her out in person. We are selling the Cape Dory 10 this spring. The tie off in rockport belongs to a friend. The new boat will live on a trailer for now.

Holy Cow! I just saw this thread - and you are flying on this thing. It looks great. Gonna be a beauty I'm sure. Can't wait for more... I'll wish you luck too - but it doesn't look like you need it.
Tim

[Tim Marchetti]

Thanks Tim, still a long way to go.

[Tim Marchetti]

It has taken about 36hrs to get to this point. This includes setting up the CNC mold and sawing all the strips. Using full length strips has made it quick and easy. I also don't worry about gaps and open seams. I will pay the price with a little more goop and sanding. The seams are all tight on the inside, giving me the option of leaving some or all of it bright.

[johnno]

This is magic to watch...I hadn't picked up this thread before. Thanks for the great pictures and their frequency!

[Tim Marchetti]

Thanks John, I’ve been quietly watching and admiring your build as well.

[Michael Wick]

Where do I sign ? I either want to crew for you or race against you. Or both.

well you'll have to crew. Racing is not my thing

[Tim Marchetti]

My mind has been opened and I'm starting to like the idea of a balanced lug. So, here she is with a 140 sq. ft. balanced lug. My wife likes the dark red hull, what do you folks think.

[Michael Wick]

With a balance lug rig, move the mast further aft. With more sail forward, she won't be so hardheaded going downwind ? That is how I used to rig my MacGregor canoe. Okay, no racing, but she's going to be fast!!

This far along at only 36 hours is remarkable. You're not

...are you?
Definately Amazing.

[Clinton B Chase]

Tim, if you let the bottom part of the luff project in front of mast more you'll get more of a self vanging effect. As drawn, depending on how the mainsheet is rigged, the boom will tend to lift a lot off the wind and yard twist off. When the yard gets in front of the mast, it can be kind of dangerous in some wind. The boat begins to yaw a lot.

You can look at Oughtred and Storer balance lugs for guidance. Also Garstide's.

[Tim Marchetti]

Michael and Clint, Can you point me to some lug rig design resources so I can educate myself. The rig I have drawn was borrowed from Vivier's Ilur, just to see what it would look like. I was thinking that the this rig would work, but may need the adjustments that you both suggest. Isn't the sail's position on the mast easily adjusted by moving the parrels? If so, then the questions is where do I step the mast? If I can't nail it down on "paper" then I thought I could rig up a temporary adjustable mast step/partner to figure out exactly where it should be. I appreciate any information folks have to offer, as this rig is new to me. Grazie

Thanks Tim, but not even close.
The CNC mold and using the full length strips right off the table saw made it fast. Now that I have to fit both ends of the strips, things are going much slower. And like I said I will pay when it comes to fairing and goop

You'll want it to look something like the Goat Island Skiff.

[Michael Wick]

You can move the Parrel beads on the sprit and the boom around to get adjustment. That will move the center of effort forward slightly. I planned for two maststeps in my melonseed MOGGIE.

[Tim Marchetti]

Thanks Michael and John. Has anyone written a book on lug rigs? or, is there a book on rigs that covers the balanced lug?

[Tim Marchetti]

I had sometime yesterday to work on the boat, but it was cold and snowing. So instead of finishing the hull, I cut some cute little greenheart blocks. Here's the rough assembly as they come off the machine.

[darroch]

This is going to be a great little boat - and very soon, apparently!

I won't venture my uneducated opinion on the rig, but I have to ask: Do balance-lug booms sweep across at head height? I've never seen one in action.

the boom shoul be just high enough to miss the helmsman(me). The rest of the crew is on their own.

[darroch]

Spoken like a true singlehander...

[jsjpd1]

Boom at head height is how it works on our boat. Good communication with the crew is key here. When it's time to come about the helmsman calls, "ready to come about?" At which point everyone shouts, "ready!" and ducks. Works like a charm.

Nice boat Tim.

[Tim Marchetti]

Drinks all around! I just put the last strip on. I'll take some better pictures tomorrow after I remove all the temporary fasteners.

[timo4352]

Good for you. Looks great.
But don't you glass the outside first - before removing the frames, I mean? Isn't that how the canoe and kayak builders do it?
Tim

[Oyster]

way so cool tim

[Duncan Gibbs]

+1! Jolly good show Tim!

[johnno]

Well done, great milestone!

[Tim Marchetti]

Thanks gents. I'm looking forward to taking a plane to her tomorrow. Still a long way to go. My glass and epoxy came today. My goal is to have the outside done by the end of next weekend.

[Tim Marchetti]

Tim[/QUOTE
yes that is the way us canoe and kayak guys do it. She will stay on the form until the outside is done, but all the nails, screws and staples have to go. I have been removing them a little at a time to make the task a little easier.

[Tim Marchetti]

here's a picture from this morning after all the fasteners were removed. I also got the whole hull planed smooth, but the batteries died in my camera. Time to make a sanding board.

[Oyster]

tim,
i just noticed the grain flow around baby dots name, i feel like that will look mighty fine all varnished up. good job
