Re: 1979 Imperial

SUUUHHHWEEEEEET! Ice cold beer and some friendly neighbors...doesn't get much better...

Congrats! Brutha Bear! Big Progress!

Thanks Gus! Good to see the inside for a change...

Looking great!

Thanks EZ!

Looking great Bear. Maybe I missed it, but where did you find the casters for your cradle? I know they aren't cheap and I'm looking to build a cradle for mine this winter.
Thanks,
Neil

Hi Neil,

I was lucky and got them from work... They started to corrode and were changing to stainless... They were slated for the trash bin! Harbor Freight has low cost casters that should work well...

With those wheel chocks and the 2x6's sticking out it looks like it could take flight "evil keneivel " style !!
I think that was the fastest flip I've seen..

Thanks bro-

Glad you have those ckocks, it is gonna be all downhill from here on out.

Lookin great bear

Thanks Brutha Troop! I'm looking forward to geting my decks built!

did you have a hard time getting the scoff guard to conform to your hull??

Not a big deal at all... It's not to thick and bends easily...

Super job bear ....... it looks great!!

Thanks again Jon!

Re: 1979 Imperial

now that is some nice progress Bear, the paint, guards and a successful flip.... keep the momentum going

looks like the interlux and roll method worked out quite well for you

Re: 1979 Imperial

Bear, Very impressive. I remember the apprehension when you started. You have come a LONG way since then. Your work is exemplary. This restore will be one that can be referenced for years to come. Keep it up!!!!

Thanks R2!

The interlux seems very tuff!

Re: 1979 Imperial

Hey Gang,

I have a question about my stringer layout.

What I want to do is work from the transom out to the bow. First building my aft stringers and bulkheads that support the rear casting deck, and contain, bilge, storage, and voids to be foamed, then the mid section of stringers, and main seating deck, and finally bow area... Will it be okay to glass separate stringer sections to bulkheads, instead of running the stringers full length of the hull, or keel? My thought is if I do a good job glassing, and once the decks are installed it should be very strong, and much easier to design as I go... Does this make sense???

In the picture below, each blue line represents a bulkhead, and each red line a separate stringer. So If I'm counting correctly, 11 stringer pieces, glassed into 5 main bulkhead sections...

I'm also considering placing my fuel tank under the bow casting deck. I feel having my batteries in the stern would make wiring much simpler...

Re: 1979 Imperial

W/ the cap off, what's the motivation to assemble the bulkheads & stringers the way you describe? Material length vs boat length? Or to establish the deck height via the bulkheads, then cutting the stringers to fit along the hull bottom mocking it up into place & marking a finished stringer height from the height of the bulkheads?

If it's the 2nd, you could also interlock the stringers & bulkheads via a notched joint:

Then you'd have full width bulkheads & full length stringers, plus a decent joint to pin nail thru & hold them together until you glass. W/ the cap off, good joinery & thru nailing (stapling or screwing the joints together), you could possibly set the stringer/bulkhead system in & out of the boat to some degree post assembly.

In a substantially well built hull (ie: the way we tend to build them as opposed to the factory, with much more attention to detail, full fillets & tabbing etc), the stringer wood is a form, and I suppose could be built anyway that allows it to remain in the correct shape, at the correct height and orientation to each other until the tabbing & glassing is finished.

But all of that is IMHO.

Re: 1979 Imperial

I'm reading through quickly so forgive if I have misinterpreted your plans; but, given the that stringers seemingly play a more important role - structurally (than bulkheads) I would do the the stringers as solid, longitudinal pieces and just drop in bulk-heads where you need them. That's how I did mine. That way you can do longer tabbing layups on the stringers. Or, you can drop them on top of your stringers with an interlock mechanism like JB has suggested/drawn...

Again, experts may trump my opinion or say it doesn't matter... Just throwing it out there.

It's the second reason brutha! And I like the notched idea... See since I have essentially 3 decks I like the idea of using the bulkheads to determine their height. This way a single keel stringer doesn't need to be cut to 3 different heights... And like you say the wood is acting like a form, I'll not be skimping on tabbing or glassing so I feel it's gonna be very strong...

Brutha,

I've thought about that and if I only had a single plane for my deck that's the way I would go... If I use the notched bulkheads, I could have 3 stringer sections, one for each deck section, and sister joint them together. Then in way they are all tied and laminated together.

Re: 1979 Imperial

Since the deck height changes at the bulkheads, you'll need to cleat the face of the bulkhead on the lower deck side at the correct height to catch the end of the deck as it ends at a taller bulkhead. Multiple deck height changes will tend to make establishing, laying out & cutting the correct elevations trickier for sure if you try to do longitudinal stringers 1st....

But, well, you know (link)

You'll probably have much less waste in shorter run stringers, just be mindful of the grain orientation. Although the bulk of the stress is carried by the glass, the ply does bring something to the table, else we wouldn't be concerned about point loading the hull w/ 1 point of contact from a stringer....

Re: 1979 Imperial

another thought is that if you do the stringers and then bulkheads you will also keep the stringers and bulkheads isolated. so if, big IF, or when, water should happen to get into one of them the glass should stop it from migrating to the rest of the wood as well. this is more what i was/am (if i can ever get back to her) doing.

Bear, i am sure the more knowledgeable ones will be along to assist or we can always poke them with a nudge pm

Re: 1979 Imperial

BTW: My thought was that all the parts & pcs had already gotten 1 coat resin & csm prior to assembly into a frame....

Until lately, it was more banter & jibberish. But lately more helpful & Q/A posts.

Let me tell you a little story about ADHD in adulthood (although the Admiral might wish to debate that last 'fact').... Long stretches of mindless travel, emailing & talking on the phone. Interspersed w/ some actual sales meetings & in-person appointments. But lots & lots of multitasking. I often leave a post reply open on my desk top for a couple hours & add to/change it a little between phone calls. Then post it hours after I opened the reply window

And I now have a foot in both camps that I need to keep active

Re: 1979 Imperial

Bear, for structural strength, I'd advise you to run your stringers full length and break the bulkheads into sections. The forces on the hull longitudinally will be much greater and thus the need for the one piece stringers. Some mfgs don't even use bulkheads in boats of this size. If you are going to foam your hull you could prolly go without them as well. If you want some structure for your deck you cut some relief's in the top of your stringers for some 1 x 3 cross members

Re: 1979 Imperial

Howdy Brutha Bear,

My tub is also going to be a tri-level deck arrangement...stern casting, lower seating area, and front casting decks...

I definitely am NOT an engineer by any s-t-r-e-t-c-h of the imagination...nor have I ever played one on TV...or even stayed at a Holiday Inn Express...

I think I understand your plan and the reasoning for it...you would build the upper casting sections out of a set of stringers and bulkheads, then do the lower middle section, the same way, and finally build the front casting deck using the same construction method...

But my instinct tells me that most of the boats loading and stress is carried in a longitudinal fashion, that would lead me to believe that I would want my stringers as full length load bearing beams and then build up my upper casting decks with the bulkheads and any additional fore/aft bracing as needed...

Although I like JC's suggestion of the half joints...which could easily be incorporated into full length stringers...

I suppose that either design will work just fine, and knowing how well you glass, it should be plenty strong enough...

Just my .005? observation...:redface:

Either way you decide to go, I will be observing and learning as you go, go, go...

Re: 1979 Imperial

I'm not the sharpest tool in the shed. Heck I don't have tools in the shed !:facepalm: But I agree with Wood and GT . It seems it would be stronger with the full length stringers .
You'll get it worked out your making great progress !
Later S.P.

Re: 1979 Imperial

All righty then... Since my boat only had one stringer down the keel, I'll reproduce that aspect base on all the advice from my iboats brethren. But since I do not have a 15' piece of 3/4" ply, or 3/8" ply so I can fabricate a laminated single stringer like Gus did, is it cool so sister joint two pieces together? I was thinking about cutting a sheet of 3/4 in half, and sandwiching the two butt jointed ends with PL and 1/4" ply... Would overlapping the butt joint on each side by 12" be enough? Thank again for all the great advice...
