A stone and bamboo house??? now that is different, I have seen bamboo used as water pipe when I lived in New Guinea, I have even lived in a paper house, it's true, thats a long time ago.

OK how to remove varnish off copper, back in my days when I wound coils for rewinding motors, we had to burn the burntout copper wires to get scrap value back in aussie.
Take 20M of copper, put in a galvinised rubbish bin, throw in a half cup of petrol and light it. That removes the varnish. (smokes a lot, stinks a lot also, neighbours panic a lot too:)  Take out the bare copper, blackened with soot, and wash it in soap and water.
But the cupper might now be brittle, or too soft to use it.

We had to use an oxy welding flame to melt the ends of the copper to steel 240v leads, so you never know, it might work.

Anyone else got a better way to do this, other than setting fire to the joint?

Yes and with half meter thick walls, it's like sleeping in a cave!

It's not varnish I want to get off the copper but the plastic insulation. Maybe I can buy it already bare but don't think so. For this coil I used a pocket knife which was almost as fun as winding the coil and just as hard on the hand :-/

I was thinking of some kind of wire stripped that would maybe cut it length wise so I could just pull it off. Like you can do with softer insulation buy just getting it started and then pulling back.

I just thought of the answer, but it will mean some drilling and tapping a screw hole, if you are up to it, here's a method on how to strip long lengths of insulated copper wire.

Grab a bit of steel, 1" square about 2 inches long, mount it vertically in your drill press, drill a hole all the way through to the other end, the diameter of the hole to be just slightly bigger than the size of the insulated wire.

Counter sink each end of the new hole you just made.
Take the steel billet out of the drill vice, mount it so you can now drill another hole say about half an inch from one end on the billit, make the size to suit a long threaded small screw, but the next size drill bit smaller.
Drill downwards to intercept the previous hole.
Tap a thread, same size of the screw
Take the long screw, wind the nut all the way to the top of the head of the screw.
Grind or file the end of the long screw on a angle and flat (like a very very sharp screwdriver), screw this long screw into the hole you just tapped, look into the hole the wire will be fed through, and adjust the height so it will protrude only to cut into the insulation, not the copper wire. Lock the screw into position with the nut you threaded all the way up the top of the screw.

Mount the whole jig in a vice, poke the wire into the other end until it comes out the other side, now you can pull and strip the wire with ease.
Hope this helps

@ all  A Wire Insulation Stripper Jig

@all here is a jig to make to wind a NS Coil
you got to be able to cut steel and use a stick welder, if you want to power it by a motor, just get a battery powered drill, take the winding handle off and put the drill chuck on the handle shaft.   The idea is, there is a sliding rear end, which has a hollow pipe the bolt end goes into, the other end of the bolt fits a socket which goes on a mating extender bar, which goes through a loose fitting pipe. The whole lot can be bolted to the top of a table, or make a wood table from scrap and use that, or use G clamps to hold the jig down.

This probably dosent fit in here but just to let any doubters think the above 2 items wont work, here is one of my projects I took on by myself. The heaviest 8" telescope in Australia, weigning in at 2 tons, Took about 1-2 years to build. 1 locomotive drive wheel, someones fence, bulldozer clutch plates. It can be checked out at www.yowee.8m.com/dadyjim.html one of my hats is amature astronomy
