Re: Ground Signals

Also the double disc and CP shown on the signal plan cannot be physically fitted on the track plan, you need to use the first yard point as the trap and have yellow discs. The radius of the entry to the sidings looks very tight as well it will be very restrictive on stock. I would suggest you downlo...

Re: Horse boxes and race meetings

I don't really see a horsebox from a passenger train being taken to a cattlepen siding in a yard. I would assume that the journey times were usually short enough to avoid the need to water the horse and in emergency other arrangements would be needed as they would be unlikely to find such cattle pen...

Printed wheels

I note that the 2mm society are producing a new style of wheel. It is worth mentioning that the 2mm Scale Association are now using 3D printing for locomotive wheels. They are printed in stainless steel by a firm in (I think) the Netherlands. https://www.rmweb.co.uk/community/index.php?/topic/132695...

[Many thanks, Keith, for sorting this out. The problem was that I don't have the picture editing software on the computer I am currently using that I had on my old computer. Microsoft Picture Manager, which was very useful, has been discontinued.] I only used MS Paint which came with my Windows 10,...

Re: First chassis in P4

The simple solution, surely, is to have a central fixed pivot/bearing point over the rear axle. The axle hole in the chassis frame would need to be narrowed so the axle can move vertically but not horizontally. Net result 3 point compensation with no fixed axle. Another pair of your beams from midd...

Re: Best wire for collectors

Carbon based materials were also mentioned as contact materials and I wondered if this might rescue the plunger pick-up. It works for motor brushes.

The original P4/Studiolith plunger pickus used carbon but they did not seem to find favour, did anyone try them?

Re: Throwing single slips

Interesting observation Jim - at Embsay the double slips were worked from 1 lever, but the single slip wasn't. No, the double slips are not worked by one lever, in each case one end is worked by the lever as numbered, the other ends are hand points. ie a second lever but not in the frame. The numbe...

Re: Block Bell wiring

Well done, I would not worry about changing the phone wire, these don't take much current and are designed to be miles apart, small wires are fine when they are close together.

Re: Block Bell wiring

All that demonstrates that the internal wiring is not as supposed so the only way to resolve it is to trace out the wiring.

Re: Block Bell wiring

The standalone bell in the bottom two photos only seems to have E, C and L, no Z. That suggests E for the + battery/bell connection and probably c is the common return, you should be able to trace those wires easily enough. The combined instrument in the other 2 pics is more of an isueas the wiring ...

Re: Block Bell wiring

I need a separate run of heavier duty wires. I doubt the wire size is a problem unless they are very long. You do need to know the wiring inside the box, if the C terminal goes to the bell as in Brian's latest diagram and there is an XR (Bell relay) then a diode across the bell is not much use, you...

Re: Block Bell wiring

I think that I am going wrong at the LNWR block instrument end where, instead of C, L, Z and E there are terminals 1 -12. The bottom three (1, 2 and 3) being the bell circuit terminals. The internals of your boxes, in respect of the bells should be as Brian's diagram. Normally there should be one b...

Re: Block Bell wiring

Are you trying to use the original wiring scheme?
Can you draw out the wiring you have done so we can see the circuit?
It should not be neccessary to buy more.

How did you overcome the delay you were describing previously?

Re: Lever frame mk 2 and the locking frame

I have seen proposals for such but my take has been that they are more complex than the row of servos which I have seen done well. Fitting a microswitch on a catch handle is considerably trickier than just on the lever throw, and if you go for the first bit of movement then don't forget you need it ...

So, it is wired up (albeit temporarily for test purposes), and works perfectly.

Re: Another newcomer's question re wagon suspension

For 99% of what we do the cheap plastic ones are fine, very rare that I get out my micrometer and my Mitutoyo languishes in the cupboard. The the digital caliper I got was a mistake long consigned to the rubbish.
