Right, now for a bit of wood working, namely making the bases for the funnel.

I used 5mm play for the top and bottom and cut them out on the jigsaw. Once sanded I fitted the two parts together with 10mm spacers.

The side walls were then applied using 1/64th ply

are you going to pump water vapour up the funnel ? if so water vapour has problems with small tubes feeding it , you may need to do a test if you are going to use the size of holes you have in the base of the funnel , you may have to go over to oil  based smoke

Hi Peter,

The holes in the bases are just for the air intake to keep the fans fed, the two 20mm connections are for the vapour.

The fogging unit was special built for this model and tests have shown that it should produce enough vapour. Follow the link below to have a look;

Because the funnel is designed with a twin wall I can draw air down as well as push vapour up, see pic diagram below.

Hi Marmoi

Fantastic to see your build log, I have been watching your progress from the beginning when you bought the hull from Ron Dean! Sadly the last time I saw you was at the National Model Boat Show where you showed me how the turrets worked, have to say that is the best method I have seen to rotate all the guns smoothly and all together and individually. Unfortunately I probably won't see it again this year since I am in the Falklands until late November but I can see you have done a fantastic job so far and I hope to see the Indomitable next year!
Best regards

Mark,

what an astonishing build.

Great, great attention to detail and supreme patience.

Every aspect has been researched to the N'th degree.

It really is a credit to you and I'm in awe of your skills.

Sandy.

Thank you both, I am enjoying this build, the research is very interesting as I am trying to get things working correctly, while trying to get into the ship designers heads of he time.

The indomitable will be off to Haydock park in a couple of weeks, where I hope to be demonstarting some of the features and the new funnel.

Actually had a nice enough day to get the hull out today and fit the funnel to the fogging unit and it is looking good so far. I won't steam it up until the inside has been painted as I don't want any corrosion on the Brass work.

Remembered to put a 50 pence piece in for scale this time!

3D PRINTING

I have been asked about how the 3D printing technology works, so here are a couple of videos.
