Re: Alex Jackson Dropper Location

The important thing is to ensure that the magnet does not pull down the two couplings at the same time, uncoupling requires one to be pulled down while the other stays up.

Essentially just what was recommended in the original P4 instructions 55 years ago. :)

And two of them will have drive rods to make sure the blades stay in line when moved.
However with the relatively higher stiffness of model blades you can probably manage with one driv, synching two drives would be difficult.

Re: Turnout construction - Question here please.

Follow the prototype, make your switch so it sits fully against the stock rail naturally without any forcing, assemble it like that. Then the tie bars pull it away to open it rather than pushing to close it.

Re: MR INTERLACED TURNOUTS

The original P4 templates included 3-way points as well as Tandems, but none with interlaced sleepers.
I think the drawings available from NERA include turnouts with interlaced sleepers for the North Eastern.

Re: MR INTERLACED TURNOUTS

You need to distinguish between 3-way turnouts and Tandem turnouts. 3 way turnouts have the two sets of blades superimposed and of a special design, they were common on the MR and on the GER but only in yards. Tandem turnouts have thw two sets of blades seperated so one starts at the heel of the oth...

John, Are you confusing web with foot here? I've never known a stock rail have the web ground back, it would have a serious effect on the strength and serve no purpose anyway. Some designs of switch require part of the stockrail foot machined off to provide space for the switch to fit against, other...

Re: Mystery through carriage from Cambridge to Cumbria

But earlier, Neil, you said you were looking for a service that started in July 1914.
So this service running in 1910 is a different one? Or the July 1914 date was wrong?
Or the service was suspended then resumed? Or was seasonal?

Re: Shorting Out Wheel tread to axle

I rather wondered whether wheels shorted out that way would go through P4 check rails? Whichever variety of shorting strip you use the flange back needs to be cleaned off to the depth of the flange to avoid any problems with check rails, filing a groove in the flange back to take the strip/wire hel...

Re: Simons workbench industrials. 16inch Hunslet

Any planing of the switch tip is to guide the wheel onto the switch rail and not to compensate for its width. Its the planing of the switch rail that creates its shape including width and tip profile. You can't have an unplaned switch rail unless you are using stub switches. (In our scale, for plan...

Allan, is it not the case that, "if you think about it" (as the phrase goes), unless you have joggles, or undercut the blade by tapering down the tops of the blades as you say, you're bound to be undergauge!? If a B length blade (29mm) tapers from rail width 0.9mm to zero at the set (say ...
