Disguised point levers, now there's a novel one, certainly avoids having a row of little bobbles sticking out of the front of the box.

Hi Bufferston,

It'll allow one to drive vehicles as well as trains. Required items on order.

Currently the intention is to use point blade contact rather than switched frogs,
but I'm looking at fitting polarity switches activated from a spur off the main
operating rods. Why ? just to see if it can be done easily enough and have there
as a built in possible up-date program .

On my pushrods, mainly some plastic covered steel rods from a set of magazine case binders, any etxra bits, extensions and adjusters are held in place by the brass bits out of choc block connectors. They even come in three different sizes to cope with different diameter rods.

I thought I had it working reliably so time for a video.
Well just take care when working with animals, children and model railways !!
They never seem to do exactly what you want ......These uncouplings were
going so well until the camera came out.

Certainly confident we've cracked the major problems as a result more scenic
work ready to be undertaken.

No follow-up video yet but hey I have what on the surface look like reliable and predictable
coupling, un-coupling, loose shunt mode and pulls across the magnets without the train
breaking at some interface.
Sadly not without much frustrating experimenting and a rather brutal 'fix'. My fix is to pin
the wagon brakes on. Small U.K wagons are light and usually very free rolling, enough for
even plastic wheeled wagons to be drawn along the track by the magnets. We know the
boards are flat and level and will have a small bulls-eye spirit level built in for keeping level
in any locations where we'll be running the layout.

Lubricating the Kadees with their graphite dust helps to loosen all movements, but is not
the answer. In fact during the lubricating process I noted one knuckle was not moving as
it should and replaced with another, my assumption is a slightly defective coupling spring.

Experiments with light, or heavy wagons made no difference so decided that mass was
having no influence, even a heavy wagon could also creep when pulled by the magnets in
either direction. Some may say that our magnets are too powerful, but to get the consistent
and positive movement we require for at least 99% reliability that is a basic requirement.

Last evening I think I cracked it by adding a brass wire brake onto one axle of an unweighted
Bachmann LMS 3 plank wagon. Initially this was so tight that the wheels were not even turning,
but a minor adjustment allowed the wheels to turn while still exerting a considerable drag.
This worked very well, so temporary sponge brakes were fitted to all the other 9 wagons with
the result that EVERYTHING worked fine, even the loose shunting mode.

As the stock for this shunting puzzle is bespoke, in as much will stay dedicated to this layout
the additional drag will not be a problem as it would on a layout where train lengths can be up
to 60 wagons.

A solution that may not suit everyone.

Been out .... Now can show the brake !

Image

It's a small length of brass aerofoil wire superglued into a hole drilled
in the wagon chassis and partially wrapped around one axle. The wagon
will barely roll after a small push, a similar push on another wagon has it
rolling for at least a metre.

Removal easy by treating with de-bonder, taking braking off can be done
by just bending free, but once adjusted to the correct pressure I shall
leave well alone !!

Now to do the same to every other Kadee equipped wagon.

A busy day yesterday on HSII.
First I added the brass brakes to all my wagons, I'll wait for Derek to agree before I drill and fix into
the bottom of his wagons.
Then I printed letters and then cut out and laminated into visiting card size pockets, each to represent
an individual wagon. To get the required order one just picks out 5 cards. One card is a 'Joker' as this
is the loaded coal wagon that must be placed over to coal drop by the bufferstop.

Image

After that I had a while trying it out. I found that with 10 wagons in a space that accepts a maximum
of 11,I just couldn't finish the listed arrangement. Back to the originally planned 9 wagons it could be
achieved quite easily.

A view showing our two vehicles that amount to our point activating levers. It works very well and to
me is so much better than any other method bar DCC operated, no obvious levers, no switches.

Photos may be late due to PB playing up again.

Well HSII will have to go back to Derek's !!
We have started redecorating the lounge. This means emptying loads of cupboards,
moving furniture around and we have simply run out of space. The next couple of jobs
are for Derek anyway so when he gets back from Switzerland HSII will be moving.

In the meantime I've been making up a timber infill for the yard occupational crossing.
PB permitting here it is in a raw and non-fixed condition. Just the right width for wagons
(tested) and Locomotive wheels (untested). One of my much used materials, matchsticks,
looks like a timber infill as that's just what it is !!

Time to start adding background scenery.

Image

Progress will be slow though.

I said progress will be slow ....... and will continue that way,
We just might have it near enough completed by the end of July,
that's a sort of target.
Here we, well Derek, has cut and added the backscenes as well
as making the factory goods shed. Must be time for me to do
something again.

Image

Image

We have the LED lights and switchable PSU, adding lighting not
far away.
Hey this is just to shunt on ..........

My mate Derek says he's not a good modeller .... Understatement or what ??
HSII has been at his place for a few weeks as I was first busy decorating, then
preparing for running Castell Mawr at West Bay tomorrow at the clubs 'Open
Day'
So what has he been up to ? Cutting and trimming with overlaps some back
scenes as well as making the northern lights factory end building, plus making
the yard depot building and adding back scenes behind the bridge.

First the factory end

Image

Then the bridge into the yard

Image

And finally a close up of wagons in the yard.

Image

So now I'll have to do some work and match what he's achieved !!
He really has been putting me to shame with the quality and speed. At least
we agree this is a low cost project ...... when you exclude the DCC controller,
locomotive and 9 wagons !!

All in 1250 mm for a shunting puzzle.

Back at my place for a while .........
Currently ballasting the yard with a 'home' mix consisting of
Woodland scenics fine medium grey, fine black cinders, fine
brown with some West Bay sand and a very small amount of
W.S. medium buff !!

Image

It'll still need a wash of matt black paint close to the rails.
Supposed to look like ash, clinker and bits of anything else
going spare ....

The Dapol un-painted wagon looks fine now it's painted, just
a shame those roof ridges shouldn't be there. Still never
intended to be a super accurate scale replica.

Somewhere in the Midlands a small yard surrounded by
Metal Bashers, working mainly with brass.
Nettlefolds wanted some of their own wagons and obtained
a few gunpowder vans onto which they added their company
name and slogan.

The slogan came from my warped mind as Derek had bought
a load of small brass screws that turned out to be too long for
fixing the piano hinges along the enclosing box folds. He then
had to buy even more and quite honestly it ended up being more
expensive than all the hinges & wood we used !!
I thought he'd been screwed financially and so came the slogan
we added "We screw the world" There was of course a time when
we did supply screws for so much of the world it has a serious
plus personal secret meaning. We love a little humour !!

Image

They're still drying out, so while waiting before I can start on the
other side I took the photo ..... Not the best quality print, but I
can't justify an expensive printer for a few odd decals !! They will
be better when dry and sealed in with varnish.

Our latest addition to the yard shunting fleet.

Image

Image

Derek couldn't resist ....... But gave to me for fitting the decoder.
What a brute to get into, over tight screws, glued in hand rails and
all very tight. The decoder fitting was easy. I'm convinced the special
decoders are just the R8249 with a 4 pin attachment with very short
leads. I must try one in a non-DCC loco where 4 leads are all that's
needed.

Back to ballasting ........

It's good to see what a little sand can do
