Watts' - or Volts: a battery loco

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Watts' - or Volts: a battery loco

Postby Bilco » Sat Dec 15, 2012 2:56 pm

I decided that Watts' would need a battery loco. I looked at various photos of prototypes and other models and finally went for a 'generic' battery loco rather than a specific prototype - a sort of 'Clay-Bat'.

I'm using the motor unit from the last UE Inspection Car in my stash :cry:

I was going to use the baseplate from the UE and cut it down as required, but I found it to be a bit distorted, and feared that I would damage the motor unit if I tried to cut it, so I ripped the motor out of the baseplate - or rather, hacked it out with the trusty Xuron cutters.

I did my usual butchery of the electrickery and made up a baseplate from 2.5mm plasticard. That's now fixed to the motor unit ready for a frame to be built around it.

Image

Next step is to hack up an inoffensive sheet of 1.5mm plasticard and get the Plastic Weld out. Hours of fun. :roll:

Lovely building and a nice start on the loco. I have a stash of UE's so will be following with interest.

Where do you get that special "inoffensive Plasticard" from :?: :?

The sheets I use always take offense at what I try and do to them :roll:

I can machine metal to a suction fit, no problem, but plasticard more often than not defeats me :oops:

Comes in handy for delapitated buildings though :lol:

Interesting these people are selling a large two car set cheaper than the smaller undergound Ernie!

the 2 car unit is totally different mechanism, and only one car is powered. The price for the utility unit is the correct recommended price when it was first released, before being discounted. Even at the full price I think it was good value as it was DCC ready.
Amazed that they still have any stock though. Maybe they bought up all remaining stock from Bachmann, which is probably why the rest went to shops such as Home Bargain. I wish I had known last year as I could have asked them. Think someone from their shop exhibits a London Transport layout which came up north.

Battery Loco

Postby Bilco » Sat Dec 22, 2012 2:54 pm

A little more progress to report - the wet weather has kept me out of the garage, so I haven't done anything much new to Watts'.

I've made the major components of the battery loco - all two of them ....


Image

The simple basic frame and battery box with the UE mech. Mainly made from 1.5mm plasticard.



Image

The frame and battery box together - any resemblance between this and any prototype battery loco is purely accidental.

As I'm making it up as I go along, progress has not been without its hiccoughs - the axle box holes have had to be shifted towards the front of the loco by 3mm, and the battery box is a bit bigger than it started out - but I hope it looks something like something that might operate in and out of a small mine run on a shoe-string.

Still details to be added. I'm recycling the lights off two of the redunded UE bodies - they won't actually light up, but they look good. Meanwhile, I suspect a small bout of festivities is about to arrive, so progress will be halted for a few days - mai laidy waif will see to that. :roll:

As for what I'll call it - in the spirit of Ernieplex, how about Erniebatt? Actually, that's a good name for its driver .... Ernie Batt :D

Hi Bilco,
For mounting your headlights, may I suggest that you attach them to the body or the battery box where they can't get wiped out when something moves the "wrong" way when replacing the battery box? The light need not be centred either.

THe photo of the Mancha in the next link shows an offcenter headlight in flameproof case attached to the front of the battery box.
http://www.ilrms.com.au/mancha_battery_loco.htm

at the other end,
Image
the headlight is attached to the battery box and is shown just above the "Reverser" label.

I hope that this helps. Have yourselves all a Merry Christmas

Watt's - or Volts

Postby Bilco » Mon Dec 31, 2012 3:44 pm

Hi John - thank you for the photo and link. Some very useful pointers on the controls - but I had already mounted the front light on the body in front of the battery box!

Anyway, some detailling work has gone on since Christmas:

Image

The three main components again. On the motor unit I've stuck axle box front faces onto the side skirts - just a square of plasticard with a disk stuck on that, but they'll show through the slots in the frame.


The three bits put together:

Image

This shows the details in the driver's 'compartment' - controller with throttle, cabling from the rear light to the light switch, swivel seat. I still need to source a dished 4-spoke wheel for the brakes.

Another angle:

Image


I've also made a start on Ernie Batt - the Schleich driver figure:

Image

He had his legs cut off and repositioned to bring his knees up and feet back, and his right arm cut off and swivelled outwards to rest on the top of the battery box. His head was also turned slightly right with the boiling water treatmen, and he gained a shirt collar. Igor was very pleased with the result.


Finally, a couple of views of the complete ensemble to date:

Image


Image


I'll need some heavier duty cables to connect the controller and battery box to the motor and a hard hat for Ernie, but we're getting there, slowly.

Happy New Year!
Bill

Hi Bill,

Its looking great!
I’d recommend that you do a 'load test' pulling a few wagons before you glue it all together. The reason I say this is because when I built a similar design the weight of the driver balanced far over the end of the wheel-base and the wagons coupled on the end had the effect of slightly lifting the front wheels up and I had to add some lead weight at the front to get better traction and stop derailments.

Gives a new meaning to the term 'low-brow' ...

Many thanks for the comments chaps. Glen - I have put weight behind the front buffer beam - a redundant brass pin from a plug - as the beast had a tendency to tip early on. It now sits level even with Ernie in place as the photos show, but I'll have more weight well forward in the battery box, as it helps with the smooth running of the mech, so all should be well - but I'll test it before it all gets stuck together.

Battery Loco

Postby Bilco » Thu Feb 07, 2013 4:59 pm

Another trip to the garage/paintshop saw the battery loco make some progress ...


Image


Ernie Batt has been waiting impatiently for his wheels - all he can do at the moment is sit in the 'cab' and make "brmm-brmm" noises (or whatever the battery equivalent is).


Image


A view of the other side. Ernie has been fitted with a helmet with a light on the front, and a battery pack on his belt to power it - miner-chic.

Weathering to come - the painting so far has been relatively trauma-free (unusually) so I fear the worst is yet to come :roll:

Appropriate sounds for a battery trammer would be the low hum of the electric motor, and some grinding of the the gearing in whatever transmission system it has ... overall, they're very quiet in operation.

G'day Bill
Just a lovely little 'critter'. Full of charm and character.
Pity the Ernie chassis is no longer freely available.
I have just the spot for a clone on a layout in progress.

I was just wondering about Ernie. I notice in the February issue of the Model Railroad Nobbiest on page 100 there is an article on motorizing the head of the engineer so he faces the direction of travel. (And that was in HO.) http://model-railroad-hobbyist.com/
Just wondering if you would think of adding this feature, with an operating helmet light as well of course :?:

Once again a really lovely little critter.
Well done.

Yes, that's a fine looking trammer ... captures it perfectly, other than being a bit too clean yet -- which I'm sure Den will take care of ...

Many thanks for your comments, chaps. I think motorizing Ernie is a bridge too far, to quote Michael Gove (and you don't often hear people say that). As Ernie tends to the "sometimes I sits and thinks, and sometimes I just sits" philosophy, it would probably be inappropriate.

As for the noise he's been making - it was probably "hmmm-hmmm" rather than "brmm-brmm". On the other hand, it could have been one of his thinking days.
