Oh you punster you!


I am sorry to hear your batteries have been truculent Geoff and wish you a better trial run soon. I ordered a set of plans from the states for Helgoland last year. They came from Loyalhanna. I like the hexagonal turret layout for some reason!


Beautiful work Geoff  :-))

On second sailing I'm pleased to report all went well. The extra weight really didn't make any difference. Speed was a good scale 26 knots. It actually seemed to get a little faster as the time went by, probably things easing up a little. On two 6v 7.2ah batteries in parallel I sailed for over two hours with no loss in performance so sailing time is easily adequate (particularly as I have two spare batteries as well).


Gunnery trials also proved successful with all four turrets firing. I probably did about 60 salvo's in all and scored numerous hits on small boys!! Much to the amusement of their parents! (It doesn't actually fire anything obviously).


So I think I can confirm Invincible has passed her commissioning trials. No pictures this time but they would look the same as the others.


Observations: The bow wave climbs quite high up the stem. In turning on full rudder I lose about 70% of speed which seems more than Iron Duke. Working the turrets to get a full four gun broadside is complex to avoid the two midships turrets fouling each other! She seems to roll in the turn a little more than Iron Duke. It may be the additional topside weight of the second tripod and taller masts which are in brass tube. Objectively the ariels catch the wind as well.


Overall I was quite pleased.


Ballastanksian - do you have the Kagero 3D book on Helgoland?


Cheers

Hi Geoff


Great to see your Invincible finished and sailing, I wish I could say mine was but I think Iím still a few months behind. Work certainly hasnít helped in between shifts!
I presume you mean the Kagero book SMS Posen and the NMM book The Battleship Helgoland, both stunning books and I look forward to seeing a nemesis for the Iron Duke to fire at!
Iíve decided on something smaller this time once Invincible is finished, Iíve got a hull of her nemesis at the Battle of The Falkland Islands- SMS Scharnhorst. Hopefully between us all we will have a Grand Fleet and a High Seas Fleet in a few years time!

Help! The penguins have stolen my sanity, and my hot water bottle!

Hi Geoff, great news on your successful trials! Have loads of fun bombarding your local youth while you ponder your next project!


I hadn't begun to do deeper research as I wanted to get other projects further developed and then the Monitor bug kicked in. Really I do not want a workshop full of projects (any more than I currently have now!) to to encourage ennui.

After a number of sailings I made modifications to the main engines. The inner shafts are direct drive and the outer "O" ring. Whilst the speed was okay I felt I could be improved so removed the engine unit and reduced the outer pulleys by about 10% and re-installed. Whole thing was more complicated than I thought and took about 3.5 hours in all and very fiddly due to other equipment installed after the engines! Must do more planning!


Sailed her on Sunday and there was a noticeable improvement in speed - its still not excessive and looks pretty scale but just that bit faster for practical sailing. Overall I was well pleased at the result and as anticipated no reduction in sailing time due to the large engines. Total sailing was 2.5 hours and plenty of life left. (two 6v 7ahr lead acid).


Guns worked fine as well particularly given the cooler weather which accentuates the effect.


Cheers


Geoff

Ah, that magic word 'Planning'. So often done, and yet something always crops up.
