Is that all one hunk of metal? That last pic almost shows the part with the round end is sitting in another part.
It's teaching me a lot watching your build. My interest in these machines goes back a long time, at least 50 years. As you progress I begin to see how Marion were feeling their way towards acheiving strength and maintainablity in machines which were intended for very arduous work where the machine's weight on the working surface had be kept within bounds.Reading the patents and other literature gives little insight to the many hours and indeed years which the designers and builders spent and this 91 machine build of yours just illustrates the ingenuity needed. Perhaps you are giving me a lesson as to why they and their competitors embraced 'modern' metallurgy and adopted welding construction wherever possible.Jerry
Chris, I'm going to have to get some string to tie around my jaw to keep it from dropping. Very complex and precice machining here...John
