Hi
I'm just starting to light my Smit Nederland. I'm using 3v GOW's throughout fed from the main 6.4v battery via a voltage control board.
Most of the lights can be wired internally but short of building a new mast, I'm going to have to run the wires for the mast lights up the outside of the mast. I need some really thin wire for this. Can anyone give me a source for this please?

Exactly how 'thin' is 'thin' ????

Telephone cable perhaps.

Maplins carry bobbins of thin enamel insulated copper wire.

Another useful product if you can find it is "Verowire", which is much the same as above but the insulation is also the flux, making life easier - no scraping and tinning.
An alternative is to get an unwanted dead battery eliminator (the mains plug type) and give it the two bricks treatment. This will reveal the transformer which is basically a bobbin with two spools of thin enamel copper wire.
Dont go too thin as thinner wire carries less current, and you dont want a long thin fuse. LEDs generally take much less current than filament bulbs, and give off less heat.

www.component-shop.co.uk sell 22AWG cable - equivalent to 7 strands of 0.25mm diameter wire.
-
Unwind the wire from an old electric motor armature.

Just remove the outer white cover and you have 4, 6, 8 or 12 different insulated thin wires - colour coded, too.

You're welcome to a hank of this if it's any use to you.

Thanks for the help guys! Somewhere around I have a reel of enamelled wire from an old Ham Radio project. I'd forgotten about that, so that will probably do nicely. :-))

hello Meechinman.
On my Vliestromn model I needed two sets of mast lights as in real life, but at our scale the wires needed would be very obvious so I run two brass rods up the mast (before spraying) one for each circuit, using a brass tube/rod down the centre this is isolated and used as the commom, this way the only wires needed were soldered from the actual bulb to the required circuit. providing you keep everything separated by an insulating material, ie; plastic the system works quiet well, and there is ultimately only three actual connection points which can be hidden discretely deep in the model, when sprayed they then blend in with the rest of the mast.
good luck with your project.
