G'day Bob
Your little railway is coming on really well.
It has a unique character and cannot be confused with any others that I have seen.
Your modelling re-minds me of Emett's work, but it is not a slavish copy .... it has your personality stamped on it and is all the better for that.

By the way ... now you have built the crane (good job by the way) .... do you plan to motorize it :?:
It would look good if it could swing back and forth .... even if the hook didn't move.

Looking forward to your next update.

Honestly, that idea had not occurred to me. A great idea. It should be simple enough to make it pivot back and forth over the flatcar. I glued the net to ground, so I will have to make another net. Thanks for the input.

Don't know what you have used to glue the net down with, but plasticard solvent will soften PVA glue. Please don't ask how I know.

In spite of the fact that there has been no rain on the layout weeds continue to pop up everywhere. Probably need to introduce some new varieties for variation. The existing species are just about enough for my eye. I should visit the shops and look for more stationary punches.

The trains are operating very well now. The next "need" is to incorporate seperate throttles for the upper and lower loops. Currently both are tied to one throttle unit that I built in the seventies. Does anyone have a simple throttle plan that would allow control of speed and direction? My desire is to build and install as a part of layout on back side so that I can control it while it is being displayed.

Try this forum post for a simple controller. You'll need to add a changeover switch to reverse direction. The unit is good for 1A, but I would advise adding a heatsink to the regulator.

I have built a few of these, they do work quite well.

G'day Bob

If you wanted something a bit more 'professional' I notice that Maplins do a ready built controller module.
http://www.maplin.co.uk/panel-mounted-s ... dule-30310
It would still need a double-pole change-over switch, also available from Maplins, between its output and the track for direction control.
Also it has no overload protection so a light globe (car brake light or similar) should also be connected somewhere in the output leads.

I have not used this actual module .... but if it was available this side of the world I would probably use it rather than building my own, which I have done in the past.

I am not sure of your expert-tees with wires and such but from your post I suspect that it is not of the rocket scientist category so if you need any clarification just let me know.

Cheers

That looks interesting, but as it's a pulse-width-modulation device, heating of the motor does come into the equation. But it does look a gnice little unit :)

G'day Barry
but as it's a pulse-width-modulation device, heating of the motor does come into the equation
I have heard that PWM controllers heat motors more than smooth DC controllers.
However, my 'trips around the lighthouse' layout has a home built PWM controller and the only 'loco' that I run on it is the people carrier powered with a Black Beetle.
This little wagon has performed at over half a dozen, two day, exhibitions, just circulating the little loop of track, time and time again, with no rest, at a very slow speed.
Although the Beetle uses a Mashima can type motor inside a black plastic 'box' which, together with the slow running, should create conditions that encourage overheating it has never faltered or melted or even felt warm to the touch :!:
If one uses open frame motors there would be even less danger of overheating.
Maybe the myth that PWM controllers cause overheating was started by somebody who had read up on the theory but had no practical experience.
The controllers might well increase the temperature of the motor slightly but in my experience they do provide superb control and slow speed running with no practical adverse side-effects.
Any motor used in the model railway world nowadays should be able to handle both PWM and straight DC controllers without any problems.

Have a good day.

Small motors have less metal in the armature core so are more prone to heat generated within the windings as there is less of a heatsink effect. Most modern motors should be OK as DCC uses PWM for speed control, however coreless motors have no metal core and have a very low tolerance of generated heat. I'm not against PWM controllers, I use them myself. However the heating effect is something to keep in mind when matching a controller/motor/work. for example I wouldn't use a PWM (or feedback even) type unit with my Z scale motors. Half-wave rectification (a crude form of PWM) has the same effect.

Whilst displaying layouts at railway meets a lot of folks take pictures. It seemed appropriate that taking a picture of the folks taking pictures would be fair. So I have enlisted the help of photographer Joey.

Next step is to make the flash unit which will have a high intensity LED that will flash when activated.

I do like the photographer .................. a new, and novel little cameo scene.
I thoroughly enjoy all these little details that wait to be discovered......... Nice job.

Appears the little people have figured out how to lower the strawberries. Much better than strawberries splattered on the ground from falling after the stem is sawed.

While my eyes were concentrating on the harvesting I did not notice that a hobbit had appeared. This is the first hobbit sighting. I am sure there are more around. I will keep my eyes open.

Oh dear Bob, now you've don it! Thank you very much!

Now I have to build a fantasy-layout of my own.

The small store room that I have the layout in is not ideal for photography, however; I took an overall shot.

I also posted a fairly current video to You Tube recently. I had not finished some of the details along the front.

G'day Bob

Just love the overall shot.....I had forgotten just how tall the layout was :shock:

Easy to do when looking at all the beautiful close-up photo's that you have been posting recently.

The whole thing seems to fit together really well and achieves a style and look that I am in envy of.

You have inspired me to get back to my current project....thank you

Cheers

Great to see an overall shot to put everything into perspective.

When is the first public exhibition?
