Caprotti Black 5

Whilst I'm unable to do any physical modelling till my arm mends, I can still post stuff on here, so I thought I would show my Caprotti fitted Black 5. Unlike the BR Standard 2 tank, this is yet another loco with no real justification on my layout apart from imaginary use on a Wakes holiday special....

BR Standard Class 2, 2-6-2 tank

As part of my layout project, based on the terminus station at Delph, I had a need for locos to pull and push the two coach motor trains which operated the passenger service. In my approximate period [somewhere in the 1950's], these trains were almost exclusively powered by 2-6-2 tank engines. In or...

Re: Any Wheel and size!

David,
Another key feature of BR Standard [and Stanier LMS] wheels is the triangular section rim. It's not apparent [to me] if you have incorporated this feature in your generated wheel files.
I must say, the concept of bespoke wheel design and printing does sound very interesting.
Dave.

The Warwick (and other George Stotts mills of this style) was built in 1907 - somewhat earlier than the Art Nouveau movement, if I understand correctly.

Ah, that's just it. These Edwardian era mills, built using "Accrington" semi-glazed brick, were anything but dark. Satanic, maybe, but not dark. Even in the soot laden gloom of pre-clean air act Lancashire, these mills stayed quite clean, with their orangey red colour, in stark contrast to...

Re: DJH 9F - my experience so far........

Hi Terry, Because of the wheelbase issue, I used Gibson milled mainframes and the matching coupling rods for my P4 9F. The remainder of the valve gear was modified DJH/Comet. Quite a bit of work was required on the motion brackets, plus slide bar supports, etc. As Horsetan has mentioned, the real lo...

Re: GW Wheel Press

I use my GW wheel press to mount both driving wheels (1/8" axles) and carrying/tender wheels (2 mm axles). As others have described, the driving wheels locate on the spring loaded stub-axles and both wheels go onto the axle together - up to an "L" back-to-back gauge in my case. Not on...

Re: Tim V builds a chassis

You don't adjust the axle-box spacing - that's fixed by the frame etching. The two possibilities are: 1) With modern CAD generated artwork, the accuracy of the frame cut-outs and rod centres is such that no adjustment is necessary at all. I've built two Brassmasters chassis and a Comet Crab chassis ...

Re: Rotary Valve Gear Crab

Hi Morgan, I'm not sure i understand how your torque reaction tab works. The tab itself lies more or less tangential to the axis of rotation of the gear box, so in one direction the reaction pushes the tab further into its slot, but in the other it would tend to slide the tab out of the slot. Is the...

Hand point lever position

Does anyone know if there was/is a standard (or typical) distance that a hand operated point lever is away from the point it operates. There are quite strict rules on track spacing and loading gauge limits to trackside features, but I wondered if this also applies to point levers? I need to find out...

Can anyone advise the wiring arrangements for the 5 pin DIN socket to go with a hand-held Pentroller - I have a spare, somewhere, with the instructions, but can't find it just now! Ideally, a description based on a view of the tags on the back of the socket would be most useful. (Presumably, two pin...

Re: Train Heating Pipes

Yes, each coach had a condensate trap to expel condensate and there was generally a certain amount of leakage - as evidenced by whisps or even clouds of steam issuing out from beneath the coaches. In my experience, the heating was only really effective in the front 3 or 4 coaches, after that you jus...
