Hi and welcome to the Club, I also have a 3a and I am not that far from you in Cramlington, Northumberland, If you need any help or advice please ask as I built mine up so have been there. It is while it is at this stage that you want to consider doing some body strengthening to avoid some of the problems that cam develop during use, and help to get it through the IVA test. I can bring mine up so see you so you can see what goes where and how which makes life much easier
