Max, Thank you so much for the progress pictures, and especially for the machining set up explanations. I am saving it all, for possible future reference. As you are well aware, setup is a huge part of the total machining time, and you obviously have considerable experience in doing all that is needed for a project such as this, experience that will assist anyone willing to pay attention to what you share. I have been planning for a good long time, the making of a personal "pet" .577 Nitro, with a true self opening action, strictly spring cocking, no cocking levers, based on the Beesley patent, similar to the second Charles Lancaster design; differing somewhat from the Purdey, machining from S7 steel. So, anything that I can learn from you, will be long remembered and appreciated.
