240 Rebuild

[JimCt]

It's a genetic thing... those two sons likely will never understand.  The other son understood from the beginning.

[LilRichard]

Ahhh... the classic "Nature vs. Nuture" discussion applied with a new twist!

I dunno... I think that PAYING for the tools helps you to have a new understanding.  I now know why my dad got so mad when I trashed his tools!

[John Jones]

Yep, paying helps.

The youngest stepson will never have a clue.

Still sanding & fairing but I thought I'd show the cap/hull connection all re-connected & torqued down with, what it seems to me, hundreds & hundreds of screws:



Next step will be to seal the edge with a generous bead of 5200.  On the inside each screw end and nut will get dab of silicone to prevent the nuts from rattling loose.  AS originally had small little lock washers under the nuts which did nothing to prevent the nuts from backing off.  Silicone will work well because it will both positively lock the nuts but also be removable so that 30 years down the line when some fool (like me) decides to do another rebuild on her he'll be able to remove the fasteners.

Got in the Primekote epoxy primer in from www.jamestowndistributors.com so when the fairing on deck is complete I can get a coat on.  Be a big morale booster and will begin to tie things together visually.

I didn't realize they were through-bolted, I thought my cap was just screwed into a hardwood frame or something every 6 inches.

[JimCt]

My 22-2's fastened the same way.  No backer wood strips in any of these boats that I'm aware of.  Had to be through-bolted because self tapping screws would have loosened up in no time.

[RickK]

How would/do they get the washer/nuts on, on a boat with a liner? I definitely don't want that job if it's how I'm thinkin' - Houdini style

[JimCt]

The #10 truss-head machine screws pass through the cap, hull and liner.

JimCT,

This has been a very interesting and informative read all the way thru, what a project and what a terrific job!!  Keep it up, I look forward to more updates.

Thanks Mike!  A pat on the head is always nice to have but a firm kick in the pants to push ahead faster is also therapeutic now & then.  My goal, aside from getting the project put to bed is to be able to close this ridiculously long thread... and the 22-2 isn't helping matters any.

Task now is to do a bunch more finish sanding on the decks so I can get that first coat of primer on.  After that I absolutely must address the transom and get it to spec. for the I/O.

You gotta get it ready for the next time I'm in New England so I can have a ride

Yeah, me too - I'll be in Cherry Hill next week.

I didn't realize they were through-bolted, I thought my cap was just screwed into a hardwood frame or something every 6 inches.

My 19-6 had hundreds of very long small bolts/nuts holding on the cap...I guess they wanted the cap to stay on!  

[JimCt]

The length of the screws AS used for the hull/cap connection is ridiculous. They are 2" long but 3/4" would have been plenty long enough.  They also made a feeble effort of locking the nuts with simple locknuts.  If the fasteners were considerably larger than #10's possibly locknuts might've worked but on just about every old AS I've been on the nuts were either rattled loose or missing entirely.  But then again, no way Fred Coburn figured these boats would still be in commission almost forty years later.
