Hi Steve,
So i have done it (pictures below) please excuse the cable ties still on, I'm waiting for the epoxy to set.
A dremel is a hobby tool i suppose, it will pretty much cut, sand and drill any material with a million different heads (also great for grinding back rust)l, I am actually a Private yacht/ship officer and in my younger years a bit of a shipwright working my way up through the ranks so i have a fair amount of experience with a tool like this, anyway what do you think? took me about a hour to do after i stopped fussing around with cups of coffee and rain coats (typical Welsh weather but then at least its not snowing)
