What size box are you using there. I am being dense today and can't find it in the thread earlier (I know it is most likely there but just being thick today) Nice set up by the way and may borrow some of your design set up with the rebuild I am in the process of (If you don't mind).

PS yes when the hammer looks like a solution that is bothering me; it is time to go for a walk or have a cuppa in the house and not touch anything that can break.
