Dagger board case: More port half preparaitions

I started cutting the beam transport cradle to pieces in order to make mould for the rope channel recess .

Then I had to glue two strips together to get the right thickness

After planning and sanding the rope channel mould to the correct dimensions and shape it was time to dry test the pieces on the basic mould. Then I screwed the rope channel to the mould.

Sealing the mould, filling corners with putty etc, curing under vacuum.

Then I cut all the fabric and consumables for the lamination. I use 12 different pieces of carbon and 8 pieces of consumables, not including the 5 piece core and the bag. Here almost everything ready.

Tonight I removed everything again, waxed the mould a last time and put everything back on wet. Then applied the bag and pulled a full vacuum (by practical means, that is).

I obviously used a lot of resin on this one, I hope I am able to get all the unnecessary stuff out in the bleeder.

Dagger board case: Starboard half out of mould, port half preparations

I removed the starboard half dagger board case from the mould, very easy release. I use Turtle car wax with carnauba and a thin layer of Norslipp on top. The part looks just as I hoped for. Really light though stiff and strong. Lovely engineering.

Then I started the comprehensive preparations for the port half. I cut the foam and placed the HD (high density foam) parts. Then I started to perforate the HD foam parts, the regular foam is bought ready perforated, a very cost effective way to do it in my opinion. The battery on my Dremel ran out of power quite soon though, so I continued bevelling the foam sides. Then I had to reverse the "recess moulds" on top and bottom. Two layers of the MDF-lid of the beam case will serve to make the rope channel recess. To the left you can see my mods to the circular saw to make the 45º bevelled sides.

Lots of small things

It has been busy lately, and a lot of things happened. Not so much on the boat, unfortunately. Anyway, I've been working on a fix to the steering of my wife's electrical car.

And I demolished the main bathroom in our house (as preparations for a new bathroom):

I have been able to work a bit more on the bulkhead final adaption. None have been glued in place though. Here the aft bunk bulkhead shown. This time I will make the aft bunk glueing flange before installing the cockpit floor, for better access.

And I have done some work making the bow ready for joining. The bow web cut out were made using a jig and a router

I also made a recess for placing the bobstay anchor.

I have been working quite a lot lately. (I didn't do this, but I had to fix it)

And the first machined piece was collected at the workshop.

Frimann has got a new layer of International VC17m extra and a few other fixes (new boom and reefing system) and is ready for another season.

This week end I put a new roof on my garage. I also finally started the daggerboard case lamination, the mold made ready for starboard half.

Wet lay up and vacuum bagging.

This post was made using Internet Explorer (which I normally do not use, I try to avoid using Microsoft applications when there are good alternatives), and I have not been able to get the lay out right.

First time inside my boat

Last night I started to prepare the temporary hullodesis of the two hull halves.

A peek in trough the bow opening

And today I put them on top of each others. Next step is the final adaptation of the bulkheads.

Then I actually entered the boat for the first time. Quite roomy. But dark of course. Felt good. A bit later I pushed my work lamp over, I had no spare bulbs so then it got even darker. I really have to get a couple of good work lamps for the inside jobs.
The purpose of being inside the hull tonight was to scribe(?) the bulkheads along the hull, making it easy to sand down the required areas.

I did that with my compressed air mini angular grinder. Really fast and easy, and good access so I was able to do the required trimming without the need to lift the hull more than a few cm.

Make sure to wear proper light and protection when working in enclosed space!

Talk, talk, talk

It has been too busy to do any building for a short while. Today, however, I finished the taping of the bulkheads (front beam, main, aft beam and aft cabin aft bulkheads) and I also made glueing flanges on the aft bunk support bulkhead. I did however not bring the camera.

In between other things I have also received a Ronstan RF 40151 cheek block , contacted a local workshop specialized in custom building Harley Davidsons about the fabricated parts and there is also a batch of Copper Coat for the dagger board case inside on it's way.

The guys at the workshop have a CNC machine and can make the fabricated parts. They even had most of the materials in stock. The problem seems to be, however, that rods, steel or titanium, with imperial dimensions are unavailable from any supplier in Norway. This means that I either have to have the rods made, from 316 steel and/or titanium, which seems to be a difficult task. The other option would be to import those parts from the US for instance. I need almost 40 cm 5/8" stainless steel, almost 140 cm 5/8" titanium and 30 cm 3/8" stainless steel. Also the rudder pin, and the shroud chain plate pins, I don't remember the measures at the moment. I would be happy to get some hints from readers, also with regards to the frontrunner fabric necessary for the rudder case and the trailer.

I will now fit the two halves together and then glue in the rest of the bulkheads. I expect this will make the alignment and final fitting easier.

More bulkheads

Aft cabin aft bulkhead here shaped, placed and tacked in.

Main bulkhead being sanded to correct size.

Beam bulkheads

Tonight the critical (structurally and geometrically) beam bulkheads were positioned and taped inn to the hull. The aft beam bulkhead being placed and preliminary tacked in place with a hot glue gun.

I was lucky to be out and see the sun set around 9:30. The dark season is leaving!

Then the front beam bulkhead was positioned.

Using a small hole drilled from the outside to locate the exact gunwale line.

Then putty fillets and tape.

Beams arrived! Now ready for mounting bulkheads

The beams and beam mounts arrived on Monday. Really nice parts! Here out of the case travelling in the back of my car to the workshop.

Farrier Marine now provides moulds along with the beam mounts for easy laminating of the last details to the beam mounts.

The last piece of reinforcement went in to the hull side today. Next time I can start mounting the bulkheads. I'm only able to put in 4 to 6 hours a week it seems at the moment, so progress is quite slow. Hopefully, there will be more productive weeks soon.

Under vacuum.
