Thanks both.


Akira - no commissions as yet  {-) - trying to solder those curved reflectors on in alignment with nothing good to get a grip on nearly sent me loopy... a few choice words were used in the workshop


Nick - would be great to see the Coventry finished, remember seeing it at one of Ron's open days - it is a great model. I will have a look in the reference material to see if I can find anything on the rangefinders.

Hi James


I forgot that you had seen the Coventry before. I’ve managed to get some very nice 4inch HA guns for her from Micro Master- I did contemplate making them myself but making eight identical items I felt was too much repetitive modelling!
I’ve looked though the John Lambert books (and the recent ones too) to see what matches up with Coventry’s range finder directors. I have two different sorts of resin director but they don’t look correct in either size or shape. The pictures in Norman Friedman’s book British Cruisers of the Second World War seems to show a mishmash of the two resin fittings but appears to have a flatter front. Can’t seem to firmly identify the actually marque of director actually used on the ww2 Coventry.


Keep up the excellent modelling. I really need to finish some of the projects before I start anything else!

Hi Nick


There is a useful file on this site
https://www.commsmuseum.co.uk/dykes/gunnery/gunnery.htm
'directors various part 1'


Suggests Coventry had HACS mark iii, there are diagrams of the similar mark iii* on the HMS Hood site


Hope this helps!


Yes trying to stick to one project is always a problem  %%

Hi James


Thank you for the link, a very helpful website. Its confirmed that its definately the HACS Mk III used on the AA cruiser version of Coventry. Unfortunately not in John Lambert's books but I'll find a scale picture to make them. Shapeways and Micro Master have them in 1/96 but not at $32 each.

Have a look in 'Warship Modelling'. I reckon it will have what you are after in there. I found diagrams of the early 9.2inch gun mount in there for the Monitor so worth a look.


I think its a Conway title.

Hi Everyone


Spent an excellent Sunday morning with the Wicksteed Park Club testing HMS Onslow - photos attached. Great to meet up with other model boaters again for some nautical discussions!


Performance was OK after some teething issues. Main findings were:
- The weight and stability is about right, but will need to be careful with topweight as ever with warship models


- Power OK, if anything a little too much. Considering dropping from 6v to 4.8v, or reducing the props from 35mm to 30mm (scale size is 32mm ish)


- The motors were warm to touch by the end of sailing. I have disassembled the shafts, and the main source of drag seems to be the inner bearing 'G ring' - photo below - I am using Raboesh propshafts. I think these have been discussed before but I wonder if anyone has any further experience with them? The drag seems to be quite high? I'm thinking about turning up some new bearings from delrin or bronze to compare.

Is that a rubber seal? If so, is it too tight perhaps and retarding the shaft as it turns? I wondered if a little lubrication on it might reduce drag.

Yes it's rubber - seems to add a lot of drag to the shaft turning. The ID seems fractionally under 4mm. I will experiment with a few things! A small amount of bronze (ouch expensive) came in the post this week to make some new bearings without the rubber seal. It's a bit odd though as presumably Raboesch build them this way for a reason?

I think there may be an issue that manufacturers forget, and modellers know from experience, and that is models need more slack than the real thing. Miniature live steam is as slack as possible as the power available is limited and too much resistance in linkages and shafts etc can make the Loco or Traction Engine fail to run.


In the same way, maybe Raboesch did not take into account that our wee motors don't have the same horse power as their real life powerplants when designing these to include rubber seals? Mini live steam will not run, but our electrics will try their best and then make the magic grey smoke if not careful.

Hi everyone


Some update photos from the build - following a great weekend at Wicksteed was motivated to get on with some airbrushing. Really looking like a destroyer now. The paint is sovereign hobbies admiralty light grey (507C). Now brush painting the smaller details using citadel acrylics.

Thanks again for the positive feedback!


Will try to post some more images as I work through painting the details.
