Wow Rich!!
Love it man. Do it while you can and no doubt in my mind that you will succeed! Love the lines on the Carolina boats. Best of luck to you.

Thanks George, if your out and want to check it out give me a call one afternoon. I'm either at work, fishing or working on this. By the way I named it Shotgun Annie after Pops old plank on frame deadrise.

I laminated one of the inner stringers today and laminating the other tomorrow night. All are dry fitted. Hopefully all the stringers minus the fwd 30% of the inners will be done by Monday morning.

Love the name and remembering your pops. I will give you a call. I am moving the old girl to Chincoteague and going to get back on the ocean for awhile. I miss it dearly and between the marina changes here and every boat from Solomons north , above the bridge carrying charters, it's time.

In case you weren't aware CoastalRunner, you can blend the hardeners to suit daily conditions, adding faster or slower hardeners as desired. That 4364 is actually a blend of 9263 and 9287 we found ourselves using most often and Ann started mixing it for us and assigned that number (used to be called just "Indigo" for the color she mixed in). Our shop is heated so we use it year round but most of the other builders down here just use it in summertime.

Carry on the good work!

CoastalRunner, I assume your project is at GI?

Would love to stop and see it and would volunteer my unskilled help for a day if needed. I am a carpenter not a boat builder though.

Actually its in my backyard right up the street, you from the area? PM me a number and I'll give you a call. I'd love the help. It interesting, when ever people stop by I have fun trying to explain how what there looking at is the foundation of a boat.

Bill, I'm really glad you saw this. I was hoping you would, as the forums cold mold expert, your observations really helps. I've read the fight club front to back A few times and caulk up much of my book smart knowledge to you and the other that contributed. I reached out to Paxton and they don't stock the "slug", I was surprised as I figured that's where you guys get it from. My plan is to move to the faster 3:1 once the temp drop below 60.

One subject that I'd love to discuss is scarfing. On my build the longitudinals I've been laminating are on the flat with 8:1 scarfs alternating horizontal directions. I've viewed all kinds of builders scarfing all kinds of ways. From just butting the faces to scarfing vertically, JB does this. One of the big question I've had is location. Should a scarf be under a bulkhead? At first it seem like a good idea as it would support the scarf. Then I figured the bulkhead would act as a hard spot and may weaken the scarf under repeated flexing. What is the best way and place to scare the stringers on the flat. I know you laminate vertically, but this was the way the past boats were built so I figured I'd stick with this.

The past week or so has been leveling, squaring and making the port and starboard sides perfectly symetrical with relation to the strong back. It was pain staking taking multiple measuments on every station. I'm currently good up until station 8. Blocks at every stringer and keel notch are level to each other, parrallel to the strong back and square to the centerline. The keel is in plane from 21-12 then the curve begins, this boats always had a small keel built on to it. The stringer are in plane from 21-14 then begin there curve. It looks like the outboard will not need to step down to 1x but the inboards will at around station 10. The stem is going to be laminated out of 1/2" x6" mahogany.

After that I began scarfing longitudinals. I did a few for the outboard stringers. Once I got the technique down I did the the keel to station 7. I tried a scarfing jig and a band saw, a skil saw and a planer ended up being the fast way for me. Then I roughed up each layer with a ange grinder and some 80 grit, ace toned them off and laminated them together. It was a bit damp out this morning due to yesterday's rain so I ended up waving a shrink wrap torch across then to warm and dry them up. It was a messy job as I think a 3/16" notch trowel would have been better then a 1/4", lots of squeeze out. Thank god for slow cure hardners it took 1.5 hours to wet out the wood, spread the glue and clamp. I'm using CPD 4528 resin and for now the 4364 hardener, I might go to the 9287 if needed for longer gel times. Boy you need a lot of clamps. Then we've had pouring rain all after noon.
awesome build project. On the topic of symmetry it caught my attention since I do this symmetry thing all day laying out body panels day in and day out designing automobiles. I used to watch the clay modelers do it in clay and they could get close, but nothing like we do it with the software we use - it's dead nuts. I run analytic curve curve graphs all day long across panels for exact highlights.

Keep up the good work.

We do get a lot from Paxton and Bluewater but they both have cut stock down, ask your rep if they can order a jug on their next shipment from CPD, shouldn't be a problem.

I wouldn't worry too much about scarfing, with that many layers your main goal is to offset joints a couple jig frames apart on adjacent layers. With your horizontal lamination it's much easier to offset and if you want, a taper from side to side is pretty easy to add. Those stringers are massively overbuilt by design so you have plenty of safety factor to work with. Just make sure your transition to thin strips forward is staggered as well.

you can also make it easier on yourself using screws and washers for the laminating instead of those clamps. When you dry fit pop in a couple screws and they will register much better when you spread epoxy and not slide so much! We use #10 coated steel square or star drives with fender washers on a pre drilled 4 or 5 inch grid pattern and cordless impact drivers and pull the next day, do not leave longer! Buy them in bulk and throw them away after two uses max!!! They get stressed and will break. Get some screw extractors from mcfeely's, you will use them! We tried using stainless and bronze but leaving them in but quickly stopped, it's heck on planer blades!

Thanks, I visited Bluewater's site. They have a great selection of CPD products.

I guess I'll continue to scarf as I'm almost done and no sense changing it up now. Maybe on the next boat. I'll convert to step scarfs on the 1x inner stringers.

I got to a good point, but short of my goal. 3 stringers got laminated, one didn't, but it's ready. Just ran out of time. Gluing up the other side was a 3.5 hr deal. Just didn't have it in me late this afternoon.

Chris, give me a call one weekend morning over the next month there will be some fun stuff to work on. Mainly the transom and shaping stringers.

I relearned a old lesson, clean us as much glue prior to leaving as grinding it of later suck.....

Also picked up a pallet of what I think is Cuban mahogany as per wood database. Weaver boatworks had it for some time. They got it from a guy that use to plank his hulls with it, he retired. It's all milled to 3/8" by 6" - 8". I plan on ripping it down to 5.5" and laminating it into the stem.

I'd save that mahogany for the interior.

Spent the last week working on shaping deadrise into the longitudinals and assembling the transom frames. This was fun for me as I feel the transom of these boats is one of the portion that can really set the boats apart. Plus there is a bunch of rabbiting and scarfing to do which makes it more fun.

Plan is to laminate section each day for the rest of the week. I still have to block out the riband areas between the verticals, block out the verticals on the inside of the deadrise boards running athortship.

I ended up adding 1" of crown to the transom cover board for a total of 3.5"'s.

One of the ribands is following the crown of the cover board to to eventually act as a ledger for deck.

Its very interesting, Ive been working on glass boats all my life. Working on a all wooded boat, cutting and fitting each piece of wood one by one the boat begins to have a soul. Feeling your shoes fill with planer shavings, having sawdust everywhere it feels very organic.
