The making of an open fishing boat hull

 

Last week Fiona said to me that she could not believe the number of steps involved in soldering the fishing boat hulls, masts and sails together. She said it could be interesting to document the steps. This prompted me to contemplate three blog posts on the 100 fishing boats: making the hulls; making the sails; and soldering the bits together.

This blog records most of the steps involved in making a hull such as the one in the opening photos. The process starts with developing a prototype and templates - below.

Because I'm making at least 100 hulls  the next step marking out 100+ blanks and cutting them in the bench top guillotine. Lovely patinated copper from a hot water tank.

Each blank is folded in the vice - I use a trick with aluminium jaws for this.


The folded metal is marked up using a folded template; and then cut using the guillotine again.


Each cut piece is hammered on the anvil to create the curve of the keel and ribs of the boat. The photo below shows some forms hammered and others to be hammered.

Five 'tools' are used to form the boat from this stage - see photo below.

The hammered forms are progressively opened using: oyster knife, cooper's barrel chisel, brass weight and 30mm dapping tool.




The final forming is done with a soft nylon faced hammer on the panel beating stake. The shape is 'tweaked' along the way with metal shearers.

The formed hull is then ground to finesse the shape and remove sharp edges.

And the final product is what appears below.


Now just repeat most of that about 110 times!!!

Almost on an industrial scale

 

Before we went to Scotland I had finished forming 20 boat hulls and 20 sails. These are part of the 100 boats for the fisher installation in the Scottish exhibition in September. So that means I need to get cracking on the other 80 plus a few spares. The opening photo shows 85 folded and cut copper pieces for the boat hulls. The photo below shows containers holding metal for both sails and hulls - packed up before going to Scotland

Following are a few images of: the folding of the last 20 or so copper blanks, marking up the folded metal,  cutting in the guillotine and the heap of offcuts beside the guillotine after cutting 85 forms.




Ending with another photo celebrating patina.

The next steps are to hammer the 85 forms, open them into hulls and grind the sharp edges off. I will probably get on to that this coming week. You can understand the title when you think about the effort one puts into such a huge multiple production.

Overwhelmed by a perilous ocean

 


I have completed another of my pieces for the Vessel exhibition. It tells the story of people forced to become fishermen in tiny open boats in the huge rolling waves of the Atlantic Ocean.

The huge overwhelming rolling wave is depicted by a patinated copper coil salvaged from a hot water system. The small open boat is made from fold formed recycled copper and brass sheet. The metal of the boat is fire blackened. The boat rides a piece of drift wood - like riding a wave within a wave. The copper coil is about 300mm in diameter and 350mm long.

A mixture of process and completed images follow.








I love the simple strength and story telling nature of this piece

Leaf installation in the making

 

Today I was able to progress three related leaf-form projects: a small installation of 7 largish leaves on stems; a larger installation with 15 leaves on stems; and a trio of medium sized leaves. The photo above shows a stash of the leaf-forms that have been hammered - but more so the lovely fire colour on the copper again.

Warning - process photos follow.




And then there are some photos of the patination process - lovely green-blue colour on the copper. To get the patina solution to work I ground the fire scale and other impurities off the copper leaf-forms and polished them with a wire brush; and then applied a diluted patina solution. Takes about an hour for the solution to work and the metal to dry.



I did get to patina 9 leaves from which I will choose 7 for the small installation. Once I have given the patina coat of fixative I will then rivet them to the stems - but that is for another day.

Patina, pickle and production


©2020 Barry Smith - Patinated 19cm long copper leaves
I'm making a stash of patinated copper leaves for the DEP galley-shop.  It has been quite some time since I have made copper fold formed leaves. I'm making some that measure about 12-13cm in length; and another batch about 19cm in length.

Warning process photos follow.

I will give the leaves a coat of matt varnish to fix the patina; the leaves will then need a grinfg to get rid of sharp edges and create a few bits of raw copper highlights - maybe I will get to that over the weekend.

Cuff bracelets

©2019 Barry Smith - Silver-plated cuff bracelet on polishing cloth with small corrosion spot
I recently sold my last cuff bracelet made from high quality silver-plate that i usually cut from vintage silver-plated placemats if I have them in my metal stash.

With judicious cutting I can  get 4 bracelet blanks with good pattern out of such a placemat. Sometimes salt has been spilt on the placemat and that erodes the silver. This placemat was pretty good - just a couple of small corrosion spots.

I used my new vice bending tool to get really accurate bends.

To reduce the hammer marks on the pattern I covered the metal with duct tap and did all the heavier hammering with the tape on.

The forms were bent over a 50mm aluminium pipe held in the vice; and the final hammering and polishing was done gently. With the gently hammering and adjusting three really good cuffs were made and one other that has a couple of small corrosion spots.

It is good to have a few of these classic simple cuff bracelets back in stock.
