Gadget,
I am looking forwaed to some more pics of the Gingery builds you are doing. They look awesome so far. Is the boring bar you made improvised by you or was it spelled out to do it that way in the text? I like the whole idea of bootstrapping one build with using the prior builds to make the new parts. And casting all of your own parts is way cool too. Goood luck with the continuing project and please dont forget to snap pics of your process as you go. It is very interesting to an old geezer like me, who had to make parts for obsolete machines for too long.
