It turned out that the cells I ordered were different to the ones used in the video.
There was not enough meat around the neck of the valve to drill the 10mmm hole to accept the female half of the crank nut.
So.....after drilling...... had to open the neck gently with the smooth end of a drill bit and then press in the nut in using "Number 1 Sons" vice.
It's all held together with conic friction at the moment.
When the Liquid steel turns up I will glue and fashion it all together properly.
So.....to avoid the same problems I had.....try and order..... or source...... the
correct cells as used in the video.
The wick I have used is years old and from an old cheap Zippo lighter.....the new wicks when they arrive will hopefully be better.
As far as drilling out the valve where the crank bolt fits in.....a pillar drill would be a huge benefit......to control and accuracy.
Happy how turned out though.
I am using an old vape fluid bottle to store the fuel and fill the cell.......works well.......and no fuss.
It was a right faff not having the correct tools.......... so I don't think I will be volunteering to make any more.....sorry chaps
Further update when the rest of the bits turn up
