The saga continues.
The Zippo Wicks turned up yesterday.....ordered from a different seller............ with an eye for detail this time
Very disappointed with them.....did not burn at all well.
When fist lit they give off a nice flame but very quickly burn down offering a very small flame that is no good to man nor beast.
The internal of the crank nut is 5mm.......will be trying a thicker cotton wick and doing away with the brass rod insert so it will fit.
It may mean I have to drill out the internal of the crank bolt to accept a larger diameter piece of bar to accommodate the thicker wick.
Failing that......I will have to buy some more candles
