I think we are of a similar approach - though mine is just on the back of an envelope at the moment. I think I'm aiming for less wood - more 'stripped down'.
Based on a suggestion from another member, i'll probably cut out a model of the action in MDF (i tend to have quite a lot of offcuts around the workshop), and then work on the outline of the stock to accept it to see how it fits. The Donor is hopefully going to be an Air Arms sidelever that
Binners has suggested when I see him at Kempton end September.
