Orca by FlyingFish – Scale 1:20 - from the movie Jaws.


Recommended Posts

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.

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

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!

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..

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.

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

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.

Ribbands are 3.5mm square and 650mm long.

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.

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

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.

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

Thanks for the thumbs up!

Still steamin' and bendin'.....

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.

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.

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?
