Stainz (or similar) battery conversion?

Found this thread while searching.

How did you get the green/yellow wires inside the cab? Where I struggled these wires inside the cab. In fact I failed to do so that's why these are hanging like animal's tails outside the loco

As you can my botched up job here.

I would be happy to convert this loco as manual control only (so no need to add RC parts). If I somehow manage to get wires insides the cab, will be it possible to replace AA batteries? Since the cab roof can't be opened, I wonder whether that would be feasible.

You could drill a hole or file a notch into the firebox moulding inside the cab.

Why not use rechargeable batteries and fit a charging plug to the cab or rear of the cab ? A dpdt switch would be needed to enable the batteries to be charged without disconnecting the motor drive wires.

Not confident with drilling How easy is to remove the glasses from windows? That would give some holes to carry wires.

If it is too complicated, I might just be happy with manual single speed control (and may be using LM317 voltage controller, which I already have).

Not confident with drilling ........

For easy drilling of small holes in plastic parts, get yourself a Pin Chuck/Pin Vice and a small selection of decent drillbits of suitable diameters....

Example (many other types available too):

You just spin this between your fingers, it's MUCH more controllable than a power drill if you're not confident with using something like a dremel, great for drilling small holes to pass wires through and it has loads of other modelling uses.

Also, whether using a Dremel, small hand drill or a pin chuck/pin vice, put a piece of masking tape over where you're wanting to drill and mark where the hole goes with a sharp pencil. This will stop the drill slipping as you start off.

Excellent hint, Playmo..... a starting mark is always a good idea to locate the tip of the drillbit, I confess I normally do that straight onto the plastic with either a scalpel/craft knife tip or anything else pointy that comes to hand, like a small Phillips screwdriver - but don't say that to any serious model engineers......
