Re: Wainwright H Class P4 conversion

I found them near-impossible to disassemble if you get the quartering a bit wrong, as the boss will not let go of the axle... . The original P4(Studiolith) ones have a taper fit between bush and axle, like the flywheel on a Mini or Morse drills in a lathe, the come apart very easily with a sharp ta...

Cone depth is very consistent if you stick with one supplier

Re: P4 wagon Compensation(springing)

Watch out for a peculiarity - waisted bearings have shallower cones than plain which I am convinced is a drawing error. There's no obvious reason for this but there's no mechanism for changing it. Its a bit more complex than this, cone depth is not very consistent, Masokits provides a cone depth ga...

Re: Advice sought on point rodding routing

I reckon I should take the rodding along the platform edge from the signal box, across the rebuilt coal siding and then presume that the original run wouldn't have been moved when the siding was removed, that would leave a track width gap between the rodding and the main line. That makes perfect se...

Re: Modelling loose heeled switches in 4mm

Phil,
It would be finger trouble, you did the 'place in line' twice, but both times for the same image, hence the other image just appears at the bottom.
You can just go back in and edit it.

Re: GWR, London Transport lines safety trip-cock

Tripcocks were required on the widened lines and post steam were fitted to the diesels working there, 23, 24, 31 etc. Also required for the Hammersmith and City and 3 2251 class locos had tripcocks for that. Trains running into Paddington Suburban (platforms 13 - 16) also required tripcocks which wo...

While I'm thinking about it I'm also thinking about, but rather more hazily, the only bit of wholly cosmetic modelling on the project, the cylinder drain cocks.

Re: Correct Roof Colour?

My recollection of looking down on passing trains from overbridges back in the 50s/60s is that the roofs were never clean, except the occasional ex-works example, as in the photos above but rather filthy with soot including a good supply of small cinders from the loco exhaust so quite a textured eff...

Re: Congratulations to Dave Franks et al.

I do have a curiosity question for Alloa experts. Is the double junction diamond just near the trap point a switched crossing? I assume it should be, even in 00. Most low speed double junctions in the Uk manage without switched diamonds, ie the K crossings will be 1:8 or less. Switched diamonds are...

Re: The Burford Branch

'Traditional' semaphore signals with wooden posts were braced by guy lines, which countered any instability in the potentially flimsy structure itself. Not just wooden ones, tubular and lattice post steel signals commonly were guyed also. Getting back to the water tank, I assume the cage on the lad...

Re: Modelling loose heeled switches in 4mm

You still need a set when you have joggles. The joggle is to allow for a thicker switch tip. The set is to make the stockrail sit at the same angle as the planing on the back of the switch so the stock rail and switch fit together properly when the switch is closed and both gauge and flangeway are p...
