Hi there Dave J
regarding information on the British Power Gun Boat - have you a set of plans by John Pritchard? for this particular vessel - as you can obtain a lot of information from these plans
Also, Christian (on this forum) / MTB Hulls is a mine of information on Coastal forces - he will surely help/point you in the correct direction.
After a bit of head scratching and a cup of tea, I always have a tea break when I need inspiration %)
The Glasgow Richmond club used to run lots of 1/72 scale warships.
The favoured motor was the Deccaperm. This gave just under 4000 rpm and the whine from the gearbox sounded almost like a gas turbine.
The T42 props turned out board, see the book on T42's, which I don't have to had unfortunately. I can also tell that the hulls on these ships was never, ever, flat and smooth as per the model hull, they suffered if that's the right phrase, from "Tin Canning" from new. That is the plate went concave between the frames and the stringers when is was welded in place, because of the heat from the welding process and the thinness of the plate which, if I remember correctly, was half an inch.

is the Marriott book? if so cant find your reference, just a good picture of the prop, but even that could be misleading as it is variable pitch you would have to know if it was forward or astern O0 Personally all my grey funnel line all turn inboard, choose this at it was what a RN ME told me, and to be honest it works a treat, same performance in both directions so I am happy :-))
The CPP Propellers on T21, T22 and T42 RN vessels all turned Inboard Chaps. I made a living taking them apart and putting them back together at Devonport for about 14years. As well as wrestling with the Hydraulics on all 21's {:-{ , early 22's & 42's. On later hulls of these two classes, the system was much simpler.Hi a very nice tidy build an readin your thread I came across the above quote now ive just finshed building hms Norfolk type 23 in 1/72 scale an this prop turn business is getting to me as ive been told that the props turn outwards an that's how ive got mine goin.But which way are you doin your T42 AN THE QUOTE does;nt mention the type 23 ?
Nice to see you are still alive and kicking Rob, I will be in touch shortly.
Awesome progress Jon!

As we have come to expect from you Jon....very nice Work!!Sorry Jon for buttin in on your build thread but HI Nige so with my props turning outward for ahead its correct im askin this Nige as I have a hms tiger build thread just below this thread an I will need to know if this is the same case for tiger with the helo vershion ? An Nige any further notes on this or any suject could you please put them on my HMS TIGER build below as I don't want to hijack jon's thread cheers
Hope you don't mind if I answer Chris's question regarding his T23.
Chris, you have your props correctly fitted if turning Outboard when going ahead. This is in common with several other classes of RN Ships also fitted with fixed pitch propellers. Whitby/Rothesay, Type 41/61 and Leander Class Frigates. County and Type 82 Destroyer, Invincible Class Carriers.
Two pictures of T23's, one with the original 'petal' bladed design (Iron Duke). One with the later skewed design (Sutherland).
Hope that puts your mind at ease.

HI Jon many thanks for info on your props direction an as you say I suppose right or wrong well ive got my props goin outwards out wards an she sails great so I think i'll leave it as it is cheers
Hello Chris, Righly or wrongly I have my props turning inward when going forward. During the build I tried to find a picture of the batch 3 props, to confirm. Never found one, so went with inwards. Jon
Hello Chris, Thanks for the encouragement. The stantions I use to get from John R Haynes, but he has closed down his web shop. You can email him and he can still supply. But, they are now avalible from the Fleetscale shop, link below. Regards JonHI again Jon many thanks for the link for the stations I will proberly get some for my hms tiger when I get that far are they very strong ? as I sent for some other 's on my other ships an they were quite soft an bent very easy as when ever I had the boat on the water an wanted to bring her in people always grab hold of them an they bend an then its a job tryin to straighten em out

Hello Chris, being photo etched brass with a thickness of less than 1mm thay are quite soft and do tend to bend easily. What I do is thread the brass rod (0,5mm) through each of the holes and then solder each joint, this create a stronger assembly. Jon.Yes Jon that's what I did an they still bent as people are not carefull enough I normally use billins stanyions as they are very stronge but they are now way to dear to buy when you need hundreds of them but thanks for your reply an yes the 1022 big radar was murder to build as mine in 1/64 scale was about 4" across but lookin at your build skill's I don't think you will have any trouble you will get it done :-))
