Geoff, You've been quite for some time. Too busy rigging to post? -
Zone 4 complete. 4 to go. Pictures follow. Note: the experiment with the rare earth magnets as clamps was failure. The magnets I got were too small in diameter. I can barely separate them. and when I try to position them between planks they reconnect. Weaker magnets were manageable but didn't have the holding power. I'm getting to the point where I can't use clamps. So, I've got to prep the bulkheads and planks very carefully so that when I glue the planks up, they lay the way they're supposed to. Sorry, no pictures of the experiment. I'm going to try one more time with larger diameter magnets. Stay tuned. Note to SUBaron (Andre): When you shape the stern filler blocks, pay attention to the way you flare the aft end of those. You can't really tell from this photo, but the angle coming to the stern isn't flat enough. The aft end of the planks need to run all the way to the the rabbet. If the filler block is too rounded, the ends won't reach. I just spent an hour with chisel and x-acto knives to modify the shape. I may have a small gap to fill with filler for the absolute aftmost portions of the last strake I just added, but for the next four or five, I should be good.

What a fantastic video! Thanks for sharing. -
Good question, one that I've been asking myself from the beginning. The photo below, from HIPEXEC's log here at the site, shows how it could look without copper. (He built the Constructo kit, which was the kit I purchased 10 years ago and abandoned within a couple of days of starting my own build log. I liked the way it looks, but the instructions seemed sketchy to me. e.g. they have you plank before adding the keel, which just seems wrong.) Now the Constructo kit came with material for a second planking - the look of which I really like. I'd have to stain to approximate that, but then I think the copper would get lost. So, maybe not.. I'll have to decide before I add the deck planking, which may only be a month from now. With the exception of one photo someone sent me (Jon?), I haven't found any pictures of Conny au natural. I wonder why no one's doing it that way.

Now that's the spirit! I'm glad you thought better of restarting. And. In support of your artistic deliberations, I too hope to depart from the mainstream on this build. The more effort I put into planking, the more determined I become to dispense with painting Conny.
-
I'd like to know your source for the four-corner brace/brackets as well Jon, I had a thought last night as I was contemplating how I'm going to clamp the remaining strakes in the planking. The spring clamps I've been using are no longer working given the shrinking open space at the bottom of the hull. Flipping through the Micro Mark catalog, I saw a picture of a pile of rare earth magnets. I think these would be perfect to hold a new strake flush with the previous one. They come in varying strengths. I get a small variety to try and post the results to my build log. Lastly, on days when I don't get much done on Conny, I wander through all the Constitution build logs here at the site and marvel that each build is unique.

I don't see that starting over is necessary. You can glue on some tapered scrap material to clean up the bottoms of those two bulkheads - or do as a number of others have, use wood putty to smooth the transitions. As for the deck side of the bulkhead, some careful work with a file, sandpaper, chisel, shims or combinations thereof should solve any issue with the deck when it gets that far. I went through the same thought process when I started out. Looking at scratch builders logs got me to thinking I could solve the laser cut issues by making my own bulkheads. I'm glad (at this point) that I stayed the course. Just about all missteps can be corrected. Just think of them as minor challenges. As you pointed out in a comment to me at my build log, once the planking and deck are in place, no one will be the wiser - or toss them out of the party! Regarding the earlier dilemma, I agree with Targa, the deck is designed that way. Hang in there!

I had wondered about the size of this club. Glad to be in such good company..

I'm still leaning toward an unpainted Conny, but when I see how good yours looks, I start having second thoughts. She's gorgeous! -
Zone 3 complete. 5 to go. First four, right side up. Last 4, work side up. Still struggling with the lighting. Note to self: Self, bring camera and tripod to shipyard. The camera picks up details the eyeballs don't. The symmetry is slightly off again. Oh well.. Not so obvious in this view.

Thanks for sharing. You just cinched the decision to build a display case for me!

It would be nice if somehow the proportional dividers had a similar locking mechanism. For what it's worth, the $25 Amazon offering did lock nicely. I do see the value of using the proportional dividers for the remaining 27 strakes I have to plank, and may yet risk using the pliers to torque it/them(?) into submission. Thanks Gregg By the way, I had breakfast at the Little Chef in McHenry this morning. Know it?
-
I'm only guessing here, but if I were a gambling man, I'd wager you built your own work bench. I've never seen a vise installed at the end of an arc like that. Cool!

Having strolled down memory lane (or relived the nightmare?) just now to review my adventures/misadventures in stern transom frame installation, I think I need to point out that the gap at the bottom of the outer frame piece is a smidge larger than the 1/16" that Bob suggests you'll have there. In Chapter 2.2.2, refer to photo P2.2.2-1. For comparison, I checked my own photo archive and saw that my filler piece was pretty close to that thickness. Also note in his photo the relatively smooth transitions between the outer frame, counter, transom and bulkhead R. You may be doing some fine tuning in this region. I bring it up because this will rear it's ugly little head when you start planking that area. Also take a look at the early part of chapter 6. P6.1.1-7 eg. I guess it doesn't matter when you do it, but you will be doing some tweaking. Having said all that, the planks themselves do hide quite a few imperfections.

After extensive research, I ended up with MicroMark (last image below) at well over $100. The cheaper ones available elsewhere seemed clunky or flimsy. Until just now, I completely forgot that I even tried this pair from Amazon first. They are useless for close work given the thickness of the points - especially on the small end of the tool. I suggest you pass on this one, unless you want to try machining the points to something less fat. These are cheap, but I was turned off by the fact they're plastic. Who knows, maybe a $10 investment may prove worthwhile. This is where I ended up. I think it was a clever stroke of marketing to show the dividers with the points looking straight. Notice the curved points on the replacement kit photo at the bottom of the ad. It took a little getting used to this, but they work. A caveat! I did not find these very useful for making tick marks on the bulkheads (5 marks per zone). If you press hard enough to get marks on the bulkhead, you're likely to nudge the dividers out of position. I do find them easier to use than my old drafting set of dividers to check spacing between marks I already made when marking out the zones. I didn't want to risk really torquing down that knob, but perhaps that's the way to use them to set the tick marks within a zone. Good luck

The proportional dividers are not perfect. You can't really tighten up the nut enough to keep the tool rigidly locked. I often accidentally move the tips merely by putting the tool down. I haven't wanted to use a pair of pliers on that locking nut for fear of stripping a thread. Also, you will need to do some experimenting to find the true index number to use to get the proportion you need. To get a 5 to 1 proportion, I needed to line the tool up to the number 6 on the index. Still, it's a lot better than any of the sketchy ones available at that mass online retailer.

I would guess that you're in the minority with that mindset. Several build logs have run into issues with the Stern Transom - mine included. But I love your optimism! P.S. Love that you're using Lego blocks...
-
glad you got that tenon into the bowsprit end. My guess is, you didn't make the mis-step in the Practicum.

Not at all, I've done the same thing with other build logs. I was hoping to be able to quote Mustafa when I did the same thing at his build log, but couldn't find the post. (I'm sure Jon will chime in with the particulars, however. I believe he and I were having an exchange of thoughts in Mustafa's build log). The gist of it was this, that's what these build logs and this website is for (IMHO). As to your earlier comment on the Hunt WTF moment. I can't find this either, but I posted pretty much the exact same comment about that reference to the 1/8" addition to the transom frames. Deja vous all over again.. I am finding a use for the proportional dividers after all. With every new strake, I double check the math on that spreadsheet. It's an easy tool to use to mark the distance between tick mark on the bulkhead and the last strake. I put the pointy ends on a metric ruler to get the measurement and divide that measurement by the number of remaining strakes in the zone. Turns out, there are quite a few on the fly changes. One other tool I use a LOT is a 3/8" chisel. I keep a very sharp edge on it and use it to trim the newly added strake. It really saves a lot of sanding time. You've got lots of fun stuff to look forward to. 😁

Tell me about it. I probably spend more time researching, thinking and prepping than actually working on Conny. Take your sweet time and enjoy the hobby. If you're getting stressed out, go swimming! The digital vernier caliper is a must have. I did by the proportional dividers but have found I don't really use them. But I'm a firm believer in, better to have it and not need it, than need it and not have it. But I also have more cents than sense. 😉
-
My first jog 4 zones done. 12 to go. crud, I just noted the lack of symmetry! Gotta fix that with the next strake..
-
There's a spar deck port there, and if memory serves, these ports are all 9/16" wide. For a spar deck opening, I too doubt that double decimal precision is necessary here. But then again, I'm someone who built a spreadsheet with plank width dimensions down to 1/100 of a mm. 😉
-
Being unfamiliar with the kit, I must ask, are those winch parts included with Lady Isabella? or did you build the winch from scratch?
-
Seeing as how I'm at that phase of my build, planking over the filler blocks, I can assure you that no matter how well you think you faired the blocks, and bulkheads A and R, you will be shaving and shaping with every plank that covers those areas. Ditto for the bulkheads themselves. Don't sweat in too much now. Getting close will save time later. If you are going to test fit planks now, prepare them as if you were going to affix them. Good luck. And again, I'm impressed with what you're doing with a small set of hand tools. Since I redid one set of filler blocks three times, I'm glad to have had a band saw and spindle drum sander. For what it's worth, once you get past the filler blocks, there won't be much need for fancy power tools.

Amen to that! (Yesterday could have been that motorcycle day. Almost got it down from the jack stand, where I keep it for the winter. What a difference a day makes! 72 yesterday, 22 this morning)
