Thanks Jo, Chris said he thought it had been a separate thread with some copies of the previously posted images. Must admit I thought I had received an email saying I had had a PM from Bob but the last one listed was 2021! and I could not find it in my emails this morning. Just have - it was in my spam folder but there's no record of in in 'my messages above'. Doesn't matter though.
Bob - I have found the tooling and you are welcome to have it. I see you are in Ipswich so I'm 45 miles away - if you want to visit you can see the boat and how I went about forming the roves/rivets, just send me another PM for my address
