Building a Steel Boat " Shibumi": February 2009

2/27/09

26-02-09 part 1

This is the anchor swivel that will fit into the bow tube.
I have mounted it on 10mm plate

It is tapped for the 8 bolts and ss steel nuts backwelded also.

Radius in 10mm cut with a jigsaw again.. its amazing what it can do.

Beefing up the plate for strength.

26-2-09 Part 2

The Plate is now shaped and the back radius cut to shape

Fully welded in place.

View from front, Once I have the anchor I will cut out the rest of the nose to fit it.

Looks great and is now seriously strong.

Happy.. yes!

Mock up

17th Feb 2009

I added more recent pic on the header of the blog.

Heres a view of the windlass, I will have to off set it to line the chain and finish the back end of the cone to hold the swivel.
I have also ordered the 30kg Bruce for test fitting.

I also have to place and strengthen the cleats for the bow and cut fairleads to let the ropes out.

I have to say, its getting there. !!

Nose fitting part 2

16th Feb 2009

Sides cut, shaped and welded in.

I used the original front piece to cut the filler pieces below.

I used the bit of the bottom inside bulwark to make the 25mm high step.

The centre piece is the cut out from the aft thruster hole, its the proper steel and its a form of recycling I guess!!!

The inside of the cone will get steel to mount the swivel, top edge stiffening metal and a tube to cary power for the anchor lighting.

Fitting the Nose Cone Part 1

13th Feb 2009

I used the test piece to hold the nose in place for fitting, I set the angle from the design in Cad i added to the boat drawings and lined up the bevel to copy it .

Nose piece can slide in and out as I cut out the fitting shape.

Anchor swivel head will live in the nose.

Sides cut away and nose piece shaped to get the first welds

Upward view

14-2-2009 setting the top cut to flow with the top of the bulwark.

It was really a case of what looked best.

Nose Cone (Bow sprit)

I showed this picture ages ago as it is the marked out sheet for the cone.
Some Good people at Eurofab Technologies Ltd. are to bend it on a press brake.

www.eurofab.ie

There was a smaller test piece also marked up for the setup

12th Feb we get a clear hour to do the bend as the factory is usually busy doing lots of repeat work.

First test piece 90 % correct.
We also did a piece only 2mm thick to get the bend radius correct.

Final piece ready to get bent. I had the sheet marked at 22 degree intervals, we decided that more hits at 11 degrees would give a better shape.

All setup to go. 1 piece and 1 go. !!!
The Boys weren't worried.....

Naturally the piece is 100% perfect. 270 mm Dia at the top and 110mm at the bottom.
Better than I expected.

Aft Seat

Aft Seat has the reverse design to the gas container.

Using a 30mm plumbing pipe to create the radius on the top of the seat.

Its tacked so once its welded it will be smooth

seat supports to be fitted and a centre support yet to be fitted

I will fill in the corners to be uniform.

Gas Storage Locker

Just tacked this together Friday 6th Feb, spent a few hours cutting the various bits and marking up the floor to get it right first time.

Tacked a top edge strip to allow the lid to sit against it.

Bent a bit of 50 x 4 around the seam to make the front of the lid.

Held it all in place with little tabs, then scriped and cut the lid to size

Corner to corner weld required.

The finished box,

very happy with it, exactly as per my original drawings.

the top seat will mirror it in reverse.

Cutting Corners!

I need to build 2 new things.
1 a gas storage box under the aft windows,
2 a aft seat on the aft deck. this will be additional storage and also provide space for the name of the boat.
Its picked.. but I am not telling!!!!
