Finaly got my brass portholes the ones in the photos are 8mm just tidied up the holes due to the paint so the portholes would fit,at this stage I have not put the glass in yet and the portholes are not fixed in place,i'm happy as they look great,will have to do a bit of make over on some of the paint not happy the PC picks up all the faults so when it warms up will get onto it.
I have 6mm brass portholes for the hull just have to open up the holes first.
So far very happy with the build really enjoying it still alot of work to do,will have working lights, and onboard battery charging so no more take battery's out just have to work out the best way to run wires.
