Went down to the garage for a bit last night to do some other jobs, then started looking at this and stopped......
I need to figure out how to cut these curved sections correctly, so that I can butt weld them together without having to fill in anywhere.
Cold wind stopped me before I could do a final marking out and cut, as I am still not sure I have got it right.
Maybe a job for mate Martin to supervise, so that I have someone to blame if it goes tits-up.
I guess there is not real magic way of cutting, I just need to measure, draw a line and pray.
Hope to get back onto this the weekend, if the weather holds out.
In the mean time I am looking for a small window winder shaped handle, before I make one, to go on one side, like they used to on some pumps, to start them.
