Wooden Boat Building shaft log: Episode 6 Sea Dreamer Project

More boat building on our Diesel Duck as we build the shaft log for the propeller shaft.

Great stuff. I love Buehler Boats, particularly Diesel Ducks. One suggestion; beg, borrow, or steal some long layout battens. You'll find you get more fair curves. This might be more important I some of the more visible curves later on. There is a tendency to get some "knuckles" with shorter battens. I love to see folks tackle large projects.

Nice! I love Diesel Ducks! Can't wait to see the first frames.

[@SixPointsWoodWorks]

Thanks! I can't wait either!!

I really like your saw setup with the support tables

[@mikeskelly2356]

Why not use two 2x8's and four 2x3's milled to size and glued up? That looks exactly like what you ended up with after all that cutting anyway. Is there some structural advantage to hogging out big planks in this manner?...

One trick to getting the perfect amount of resin is to simply math the volume of the glue-up. The to-be-glued area is the base and the thickness of the glue is the height. It's pretty simple, and i'm pretty sure there's plenty of Apps for iPhone or Android that can spit the volume you need. To that volume you add 1% more (or there about) to be certain and voila, you'll never squeeze glue out ever again. Also, in my opinion it fits perfectly with the carefully measured methodology behind resin glue. The idea is based on how they glue car panels today, they math the whole thing down to a square cm, which is incredibly precise considering all the twisted shapes and volumetry of a modern car.

That sounds really technical, I love technical! I want a little squeeze out to confirm the joint is filled with adhesive, but finding a way to limit waist is always appreciated, thanks.

[@nic_the_aged_woodworker]

The idea behind squeeze out is to demonstrate that there was sufficient adhesive in the joint, The art is understanding how much adhesive you should apply. Unlike the automotive industry wood workers don't have the accuracy of positioning and metering. Also the surface is absorbent. The viscosity of resorcinol is hugely affected by temperature, on a hot sunny day the stuff willnrun all over the place. Finally its pronounced re-sore-sin-ol

Good craftsmanship 👍🏻

[@TBPollock]

God Bless You, soldier on. You'll get there but I don't have the time or patience for the journey. Affectionately, good bye.

[@jeffkatzer]

Looks good!

[@TrapShooter68]

I thought the first rule of woodworking is that you always need 2 more clamps than you have?

[@thomasarussellsr]

Interesting assembly. Will the square tunnel be filled with a heavy grease to float some support for the much narrower shaft? Obviously there will be a seal of some sort at either end, just wondering about flex in the middle.

How does the cutlass bearing fit in this

[@SixPointsWoodWorks]

Hanger bolts for both the cutlass and stuffing box. Check out salt and tar, same keel concept.

[@johntripp2028]

I looked at Salt ad Tar until I went cross eyed didn't fine it. and As i typed this I think I understand. Hanger bolts at the end then nuts on the flange. My question is more on the round bearing going into a square hole. Will it be supported inside in any way. Or is your bearing so heavy it doesn't need support.

[@Oxnate]

Umm... was all that cutting necessary? It looks (and I could be wrong) that you cut out the middle of the boards you glued onto the first board. It appears that an easier way might have been to cut 2 of the 4 boards into thirds (or however much you were going to cut out) and then just glue the remaining pieces. You'd get the same shape at the end with less wear on your saw, less waste (if you can find a use for those pieces you just cut), and less glue--since you'd have smaller areas to glue to start with. Maybe next time.

[@SixPointsWoodWorks]

It was close but there is actually about 1/4" of material still left in the board. I thought about your idea but decided it was worth it to have a little more materiel in the log. Thanks for watching.

[@johntripp2028]

Percentage wise and added strength wise that 1/4 inch is a lot.
