This is how it sits as of today Feb 24/2013
- dry run no epoxy yet - all to be moved to another site for epoxy / fairing / plywood etc...
- a few minor things to do, but mainly one last step to perform... prior to moving to other site.... this is prepping of the marine plywood...includes ripping and scarfing required lengths and widths in main shop

Image

A huge thanks to my two friends John and Mike (yeah you to Mimi)... for helping me get this far!!!

As stated above... I am encroaching and competing for floor space in a very busy shop... see almost completed 17' cedar strip kayak... what a beauty

Looks great! If you get a chance take some pictures of the sheers sides from around frame one to the transom. And the attachment point of the sheer on the transom (frame 0). It would be really helpful to me in my build.

I'm looking at having to steam bend the sheer lamination's (vertical grain Doug Fir) because of the sheer's bend from frame one to the transom. Just hoping I didn't somehow "F" something up.

Yes... most tricky of them all... sheer at transom to frame 1- wow – easy does it - no pics

- after installing two laminations for the chine... we decided to re-think our sheer install strategy... even after using towels in boiled water to help bend the doug fir pcs - 3/4 x 2" @ 2 pcs for the chine
- we decided to go with 3pcs of ½ x 1.5” for the sheer (had to re-mill material here)

Ok, so I'm not that crazy after all (friends may disagree though).
I'm using 4 lamination's and it'd still a bitch. I built a steamer, but temps here have averaged in the 20's. Have to wait a few more weeks to try it.

I don't need to see how you did it, just how you ended up. If that makes sense.

I'd really just like to see a photo of how and where you notched the transom frame for the sheer.

Thanks

...as of today Feb 26... decided to add aluminum angles at transom to stringer connection in addition to the suggested wooden brackets...

...placed some temporary fasteners in battens and trimmed and attached keel to stem... in preparation for rough fairing

Image

- put together scarfing jig... shown attached to circular saw... did test run and it work's perfectly (scarfing plywood panels together using epoxy)

Image

example - side plywood panels on the cracker box will be rough sized (scarf jointed) 2' x 18 feet long

as of Feb 26 - started to fair the hull


Image

March 5... rough fairing completed... all plywood has been scarfed but did not epoxy together yet (makes it tricky to transport plywood panels at 18 ft long)


Image


... all has been taken apart today... will be moving project cracker box to new location for completion... it's coming home...

progress update... slow but sure... "The building form" - support jig is anchored (tapconed) to concrete floor - perfectly level - in straight alignment and plumb

... all frames are in perfect alignment / plumb, epoxied and screwed / plus some temporary bracing

...keel and battens epoxied and screwed... yes they are silicone bronze screws... lots of work there... predrilling (tapered bits with countersinks) - cleaning holes - inserting regular steel screws then inserting proper screws with some wax... wasn't taking any chances in snapping any more of those !@#$% bronze screws


Image



Image


Transom was slightly out of alignment, therefore had to temporarily brace while I epoxied keel and battens... nice and straight now


Image


...as you can see it is tricky to get a full size pic in my limited space...


Image

- 18' long panels of marine plywood (scarfed and epoxied) are seen in background against the wall... ready to go

- over 75% of structure has one coat of epoxy, some parts such as specific areas of frames and stringers have two coats since I will not be able to access these once the plywood layer is installed...

- getting ready to install chine logs (2 pcs 3/4 x 2") and sheer clamps (3 pcs 1/2 x 1-1/2")
