Sorry Saved. I had my wires crossed when I quoted you prior to editing my post.
As a matter of fact, what made me realise it wasn't you was that I remembered being impressed by the metalwork that you did for your build. It ain't pretty but it works.
In some ways, it is nice to see that sort of work in contrast to the pretty stuff. If it was me, I'd keep your Navarone as it is and do another one with the improvements built in from scratch. With what you learned in this build it should go more quickly and smoothly (if you're lucky). The prototype should be preserved as it is for posterity.
Sorry Jez, I'm getting a bit of a rep for thread diversions elsewhere so I'll cut it short.
