Hi Alan,
I bought a slab of high quality cast iron from College Supplies delivered to an exhibition) and obtained a copy of the crosslide drawing from the helpful folks at Boxford. I bought a tee slot cutter and flycutter for my miller (I had slot and end mills).
I cut out most of the profile on a vertical bandsaw and milled the rest out, cost me less than half of a manufactured one and I learned a lot of useful milling and boring techniques. I have a copy of the drawing if you need one. Just email me.
I used the Lathe to scribe the separate (189 degree) protractor in brass using a simple version of a Harold Hall dividing attachment and an ingenious combination of back gears. This protractor was then let into a semicircular milled slot with the ends chiselled square using a very old fashioned technique. I’ll try and find the pictures if they have not died on an old hard drive yet.
John, I would loved to have had access to a shaper, one of my favourite machines and I think most unappreciated by the uninitiated.
Terry
