Update On Water tank

Pictures taken 10-march 2009,

1200Litre Fresh water tank assembly in Eurofab







Under sides all tacked and lined up ok.
I did have a slight error on my drawing and had to fit it somewhat.



Inside ring for access hole (4 in total) with the bolts welded.
All stainless



Strip welding the baffles in place.

As of 10th April the tank is only waiting for the lid to be fitted and some pipework.
All outside welding done.

Finished raised floor

Part of an update,
Pics taken 11th March 09.

Finished new floor height



Centre Girders back in place



New Cut in 1st step to aft cabin, now there will be 4 steps instead of 3 and will be better



Aft Bulkhead getting reinforcing box to carry aft wall

Other side.

Once this was in I re -attached new 50mm angles to the aft wall and cut out the lower origional ones

New Floor height

8th March 2009

Grinding still going on and I have spent a few more days finishing the welding that needed doing
mostly under girders and impossible places to get to and I LEFT THEM TILL LAST...!!!
The outer hull is now fully complete and will only need grinding and sanding before the blast and the primer.

Some months ago I got a reference drawing from the designers showing a particular detail.

The other thing I noticed was that on that design, the saloon floor was higher than mine.

I totally ignored it till the other day. ...Why higher.?

So on friday I looked at it seriously. The other floor was 200mm (8 INS) higher. On mocking up a box and looking i felt it was too high, but the visibility was much better tru the front windows.
I then decided was it possible to raise the floor 100mm .
The view was better and still plenty of headroom.

My local supplier of steel had all I needed and the lengths were delivered friday evening.

One concern from the designer was not to add too much weight.
Total weight added 68.5 Kgs.

I started cutting out the floor girders this morning (Sunday) and by 10pm tonite it is 80% done.




100mm x 6mm flat bar 4.2 m long to sit on top of the bulkheads





I cut out the backing strips 100mm to allow the new plates to be welded. I cut blanks and scribed them and cut with the jig saw.



Bulkhead FR4 ready for welding



On the front bulkhead I added a 100 x 50mm box to build up from the angles and make the whole thing stronger,

Port side looking back completed.

As such its using all the standard parts , but just raising them.

I now have 100mm extra headroom in the engine room and more space to run ducts etc.

I will also run stuff tru the Box section on the front as there will be a hatch just underneath the box section.

Winner all round and the floor is better higher.

Hope to finish it tomorrow evening and cut in the steps for the aft cabin.

In Other news....

Stainless Steel water tank will probably get finished this week.

The grey water tanks ( 3 of them) are now basically designed should have them in a few weeks.

The Big Grind Begins...

Last weekend 28th Feb I started the final grinding of the outer hull along all the weld lines.
The sandblasting day is coming fast.
Theres a few things left to do structurally and I'm trying to get them all done before the blasting starts.
Theres probably a few days grinding left..


The pics below are only taken today 4th march on my phone so the quality is bad.
I designed a 1200Litre Freshwater tank for the front under floor of the boat.
As I moved the engine back in design I'm adding a bit of water to counter 0.8 degree.

Eurofab (Nose cone ppl) got this laser cut and its been down there for a couple of weeks waiting for time to weld it.


We got some of it tacked today and its lining up nicely.
I dont have TIG welding gear nor have I ever done it, so its pro welding here...

Front end, waiting for the other bit of the floor to get tacked.

The tank will sit across Frames 9, 10, 11. and matckes the shape of the boat exactly.

more pics when we do more on it.

Not getting any comments or mails for ages , yet over 900 views a month..

all quiet out there....?

Since oct 2007 14,000 people have viewed the blog.. thanks...

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.
