Have the frames true to within 1mm at the sheer, rabbet and at each waterline. Some adjustment needs and a couple rebuilt. Getting a sense of the shape of the hull now.  May remake the jig to simplify it and allow more room to add the floors ribs and ribbands.  Next step is to fair the edges of the frames. It's only at this stage that I feel I have a set of plans that are accurate to the original.

A little progress…

Cutting the rib pockets out using my little home made chisels.

 

IMG_7398_1280.thumb.JPG.69bcb24d489b86ef262e8d2178147635.JPG

 

The rabbet has been moved to allow for the altered planking line amidships.

 

IMG_7402_1280.thumb.JPG.36b386330be1a9b7edb3877f9e4d2f32.JPG

 

I’m learning to be more accurate with each one… might even have a half decent pocket by the time I get to No. 26!

 

IMG_7405_1280.thumb.JPG.37feff084123390c7ce650656172d64e.JPG

 

Then on to prepare the frames so that I can fix the ribbands to them without gluing, and have some clamping points for planking later…

I use a simple little edge marker for this..

IMG_7412_1280.thumb.JPG.62fa352adbdc6b94a7c8f766a3d34564.JPG

 

A bit crude, but it seems to work. When making this I wished I had a lathe and mill so that I could make one in brass, but making do with what I have available.

 

IMG_7416_1280.thumb.JPG.6e76564cf05c2182637bef100e17082b.JPG

 

Then a happy hour or two on a 16” Draper scroll saw, listening to jazz helps with repetitive tasks.

 

IMG_7430_1280.thumb.JPG.21dbdb3e2ae552b9c9e99bb5afcc0e40.JPG

 

The idea is to use my little 19mm clamps like so…

On to the ribbands....

First need to cut some new stock - plenty of semi-green field maple left, and really like the way this works with hand tools.

 

IMG_7441_1280.thumb.JPG.13b389aa962649844f09f9b4b290b855.JPG

 

 

Ribbands are 3.5mm square and 650mm long.

IMG_7443_1280.thumb.JPG.0eec7a60693c4e6ebd9b488e7090a7fb.JPG

Rather than attempt to replicate the number that would be used in life, I have opted to place ribbands where they will hold the shape of the ribs when they are steamed in. I intend to bend the ribs to shape in advance, so if I get this right they will hold in place once fitted.

 

IMG_7454_1280.thumb.JPG.232470f873831cf1cb8616740a06d6aa.JPG

 

Using soft copper wire to hold them in place to keep the clutter of clamps down. 

IMG_7455_1280.thumb.JPG.db372c6abcb64fbbc944e847dc077b9f.JPG

 

Now on to a batch bend of the ribs.... nearly had a disaster here - used the best stainless steel casserole dish to heat the ribs - almost got caught by the head woman returning it to the kitchen cupboard. Phew.

 

IMG_7450_1280.thumb.JPG.6ba4cfee29effda65e3a7e743e0b41b6.JPG

 

Hope these turn out alright... we shall see.

Got some work to do to the bow section; it will be mightily fiddly once I get to the sharp end!

All this will come off again once all the ribs are steamed into their shape, so that the frames can get their final fairing sanding, and then planking lines worked out. Oh and I need more mini clamps - lots more!

Thinking forward to planking the hull. Firstly, I've had a good look through the resources on this forum; really excellent tutorials etc - thanks to all of you for passing on this useful information - the depth of knowledge is tremendous. I've had tried to follow some of what I've read, but treat me as ignorant and you won't be disappointed!

 

Any tips or suggestions gratefully received, need my hand held here. My mind is full of drops strakes and stealers, edge setting and hood ends. Just love the language.

 

 

'Lining out' - I've no idea if this is the right way to do this, but I started by marking card strips at each station at the rabbet, DWL and sheer, then lining them up at the waterline to look at the proportions I got, S1 being at the stern.

2116760337_planingtapes.thumb.jpg.0b2fb6992929823f973cd082628a1561.jpg

 

My first thought was that the strakes below the WL would have to narrow too much coming forward until by S11 or 12 they would be too narrow. 

Strakes above the WL would widen going forward. So it seems to me therefore that the lower strakes might sweep up towards the stem to take up some of this space.

 

Looking at warlock's bow, the planking shows through the paint, and I've highlighted what lines I can see, which seem to bear this idea out.

 

1742312337_Warlockbowplanking_1280.jpg.9dadbf9ffbe6ca2963247311744adbc4.jpg

 

So reading Antscherl's tutorial, I guess my next step is to get some thread and mark out on the frames how the planks might sweep up from the WL amidships in groups to the stem and transom. Have I got that bit right so far?

Made a quick jig for thicknessing strip planking, (credits to the Open Wood Shop You Tube channel). Wasn't expecting it to be so accurate. Shooting for 2.5mm; very chuffed at the repeatability.

Progress has been steady, and perhaps a little painstaking.  But then I consider it a bit like taking a small Jack Russell terrier dog for a walk… for each single mile of the walk, the dog does two – and gathers scents and all sorts of doggie info along the way. An older wiser dog does not need to scamper about; he has learned all there is to know about the territory, and just pads along efficiently.

Well, here I am, inexperienced, tail wagging furiously but I have marked out the territory and covered the miles.  If you have stuck with me so far, thank you, you are very patient.

Preparing for Planking –

Fitted some of the floors painted in ‘antifoul’ and painted the keel and keelson and horn interior surfaces.

Did quite a bit more work on the frames fairing, trying to get as close to the pictures of Orca’s hull as possible.

 

IMG_7520_1280.thumb.JPG.889fbc59081c0ad69c9f5e2dd05401ee.JPG

 

Lining out-

As previously shown, I used card (tick strips?) at each station to mark the sheer DWL and rabbet and then used a thin plank along the DWL the see how it would lie as it came forward and rose towards the stem at each waterline. Some spiling will be needed here.

Using the reference photos of Warlock I decided on the plank width for the deadrise bilge and topsides. A few test fits to see what edge setting; bending or steaming might be needed, and a plan emerged.

Used a fan template to transfer the planking widths from the tick strips to the frames at each station. Then waxed the edge of each frame to stop the CA glue sticking.IMG_7533_1280.JPG.66c9137af7ca0e25ce835788367e05e5.JPGIMG_7531_1280.JPG.06470c0d6bf069c077981ea039f232d4.JPG

 

 

 

 

Then prepared stock for planking.

After considering Tulip and Beech of which I had some seasoned offcuts I decided to keep with the maple as it really does machine well, and my wife planted it, which makes it nicely home grown.  My only slight concern is that it was felled in December and has only had a very brief time seasoning. I recon that once cut to size and left in the shop for a few days it will do most of it is shrinking before I fit it. I also have enough to build a fleet.

The garboard and broad strakes band will have 1.6 x 5.8mm nominal planks. The commons at the turn of the bilge slightly narrower. The topside band will have 1.6 x6mm which will narrow somewhat forward.

A happy hour or two produced a decent stock which I have brought into the house to dry a little before fitting. Leaving on a radiator is a sort of kiln drying, and hopefully prevents gaps appearing later.

IMG_7542_1280.thumb.JPG.87f3090edfc698532337bd905e1cdb32.JPG

 

This mini plane is exactly right for shaving the planks to width – 2 thou per pass. I've got the blade razor sharp.

 

IMG_7541_1280.JPG.f8f6ae95c127956e47359d6ace260893.JPG

 

Ready for planking… the widths are set out on the ‘lofting floor’ and the Stanley knife jig takes a fine shaving off where needed.

 

IMG_7540_1280.JPG.fa599f6a48203c074ccd6b494a747f71.JPG

The planks fixed with PVA glue to the rabbet and on their edges, and CA to the ribs.

The garboard and first broad stake are fiddly to get at, but after that it goes more easily.

The next post should see planking moving on now.

The warm settled weather continues, and outside jobs call, but inbetween a little progress.

Mostly happy with the way this went, but one plank in the middle threw the symmetry, but pulled it back later. Sheer luck I say.

'Hooper – full throttle!'

Orca needs an engine. It will only be seen through the hatch, but it is an important part of the plot – if the engine hadn’t died, Quint would still be in one piece…

However there is no shot of the engine in the movie.

 

The only reference I can find out there for the engine suggests it was (surprisingly) a 4 cylinder petrol (gas) engine.

No idea what make, so let’s go with a Volvo Penta 130 which would be about right, I think.

A little research and scaling later…

'I'm not talkin' about pleasure boatin' or day sailin'. I'm talkin' about workin' for a livin'. I'm talkin' about sharkin'.

 

So the engine is ready for the installing on the boat. Quint no doubt would be pleased that we have got him a second hand somewhat beaten up power plant.

It's down on the dock on a pallet...

I think that the beaten up nature of the engine makes it more endearing but shouldn't the pallet be stained with oil? Noting how knackered the engine looks surely the odd seal or two should have gone?

Planning out the next steps.. spring tasks (and the start of the fly fishing season) prevent much more getting done... some guesswork here, little is shown in the film of the interior. If you know differently, I'd be pleased to be corrected.
