H28 "Larrikin" rebuild

[Larks]

I’m finally pretty happy with the camber of the cabin forward bulkhead, the camber is actually a little flatter here than it becomes as the cabin top moves aft:

Gee you may need some packers under those mezzanine joists soon.

so are you saying every cabin beam is a different curve? That’s gotta be a pain. TBH I can’t remember what mine was but I do remember a for/aft string line. Actually it must be that mine differ cos the end bulkheads are way different curvature. Only 4 or 5 beams so not too bad.

coming along pretty quick now , can’t wait to see the end result. It’ll be very nice I’m sure.

i just went and had another look at your last picture - OHS says take those f’n screws outta the bottom of that joist before you stick em through the top of your noggin.

those screws were just holding the string line for the deck height and c/l which I took down just before taking the pic.

Yes, each cabin beam will be slightly different as they'll each vary slightly in width as the cabin widens and narrows along the length, as well as in the height/position of the outboard ends as the cabin side curves with the sheer. But the mid height is essentially a flat plane, though with a slight fall to the front bulkhead for the forward 1/3 of it’s length. So each beam will require a slightly different template.

How do you work with all that lofty space above the boat!

[Hugh MacD]

That's looking sooo, good Greg! Your thoughtfulness and craftsmanship are paying big dividends.

- It’s been manageable so far, though fitting the deck beams and the deck might be a bit if a challenge ....

Thanks Hugh, I really appreciate it mate.

Greg,
Been away on holidays for a few weeks and come back to a glassing, woodworking and steaming tutorial. I am glad you got your final shape that you are happy with. No second chance on the Huon pine!

Cheers Mal, ‘hope you had a great holiday mate.

Cabin sides are now firmly fastened in place - glued down with epoxy, taped inside and out and then screwed down from underneath with SS coach screws. A bit of a challenge maneuvering them into place by myself without displacing all off the glue but a couple of pieces of PVC pipe helped:

I sealed the outside of the panels with Awlwood varnish (rolled and tipped) to protect them while handling and fitting them and I’ll sand everything back again and spray the final finnish. I expected the corner posts to need some refining to fit properly so didn’t coat them at all, but surprisingly they’re pretty much as they need to be.

Before I could cut the cabin side panels to length to fit them I had to work out how I was going to build the cockpit bulkhead so that I could determine where the aft corner posts would sit:

I’d been trying to come up with a means of retaining a clean and classic finish to the cockpit bulkhead while still having the GPS plotter visible from the helm.

I looked at all of the available swing around mounts to have it swing from over the nav’ station around into the companionway but I really don’t like that idea, at least not on this boat.

I think I have a workable solution that I’m reasonably happy with - with a few refinements yet to come in the final production....

So another mock up from scraps:

(The engine control panel is drawn on the stbd side inboard panel here to scale just to establish the size of the panels. In reality it will be mounted to the port side (inboard) panel. When the boat is closed up with the washboards down it will be secure inside the boat.)

[IMG]IMG_3616 by Greg Larkin, on Flickr[/IMG]


The front panel slots into the outboard stile, closes against a spring and is locked in place with a latch from inside the cabin. So with the latch released the panel pops out to be removed:

[IMG]IMG_3618 by Greg Larkin, on Flickr[/IMG]

Once removed it will live in a slot in the space over the GPSplotter box/shelf (from inside)

[IMG]IMG_3620 by Greg Larkin, on Flickr[/IMG]

The plotter box/shelf will be fully sealed so that any rain/sea water doesn’t leak into the boat over the nav station or onto the inside shelf that will accomodate an IPAD repeater directly behind the plotter box.


So now I can start turning that into a Huon Pine version - corners posts first (dry fitted at the moment):

Nice work Greg.
The varnish has brought out those lovely honey tones.
Looking great.

Cheers,
Mike.

[Andrew Donald]

That’s a feat of engineering to rival the Suez! Onwards to the most technically developed H28 on planet earth. Only wish I had your patience Greg.

[brucemoffatt]

Greg that's looking amazing.

Wow, thats pretty wood!

[gray duck]

I don't think any of us can imagine building that cabin under that loft but you have done a beautiful job of it. Like building a boat in what we call the crawl space in Sepo-land. Impressive

Thanks Mike, cheers

[Quest]

Holiday was good thanks Greg.

Getting those cabin sides on by yourself would have been a challenge, looks like it turned out though. Looking forward to seeing the aft end magic box come together.

‘hasn’t been too much of an issue so far GD, a few bumps on the noggin’, getting the cabin top itself on though will be a whole different story......

I think this work today has been my favourite part of this rebuild so far, working out and fabricating the aft cabin bulkhead structure from Huon Pine. I’ve used mortice and tenon joints on the starboard side where the removable centre panel will be while the port side tenons just slot into the panel slots (which will be a fixed panel).

Just dry fitted for the moment, the stiles still need to be sanded and I’ll work on a little more refinement to the joints but I’m really happy with how they are looking:

Coming together well Greg, I can imagine you’re measuring about 6 times before each cut. That woodwork is going to look magical once you’re done varnishing it.

[Larks]

I missed your post Andrew, but yes - measure, make a few templates, measure again.....cogitate...... measure...procrastinate........bugger it ......just piss or get off the pot......


But after all that I’m really happy with how this is turning out.....so far......

The stiles are epoxied together while the centre panels are “sealed” in Fixtech (Fix190), so that they can still expand and contract within the stiles but still provide a fully sealed exterior:

I love those little pimple knots in Huon, looking magnificent Greg. How have you fastened down to bridge deck?

[willin woodworks]

Looks damn nice and wondering the same thing? How are they fastened and sealed?

[Steamboat]

Very pretty Cabinetry, boats are furniture that float!

[Larks]

I love those little pimple knots in Huon, looking magnificent Greg. How have you fastened down to bridge deck?

Epoxy glued, glass tape (both inside and out for the cabin sides and cabin front but just inside on this aft bulkhead), M10 316 coach screws from underneath through deck frames and a few diagonal M8 screws from the top down into deck frames.

[Hugh MacD]

Beauty, Greg! I really like the raised panels in the Huon!

[Mike1902]

Lovely work Greg. Those cabin sides are really going to be a stand out feature.

[Larks]

Thankyou for the kind comments gentlemen, they are very much appreciated

I haven't been getting forum notifications, so I am just catching up on your rebuild. That is some beautiful work. I'm really digging the cabin rebuild. Your interior redesign is very different and I like it.

The previous owner of my H28 has very kindly sent me through some old photos of her build and early days. I’m looking forward to him paying a visit shortly to see how the refit is progressing and hopefully filling me in on some more of her history:
