Both the body and the shank have been machined and the threading is almost finished. The shank is 16mm diameter, the body is 40mm diameter.
Close up of the threading tool etc. I always do threading with the top-slide(compound slide) set at zero degrees. During each pass I advance the compound a thousandth of an inch or two until the thread is almost to depth, at that stage I take a couple of light cuts until depth is reached. After the threading was finished I parted the job off.
The job has been rechucked on the shank end with a piece of brass shim around the shank. During this set up the end was faced and the OD filed and emery taped to get a nice finish. That file is a special file for lathe use, known as a long angle lathe file.
As I had the Gingery shaper column assembly set up in the Mill/Drill I just disc ground and filed this flat on the fly-cutter body. Both the centre line of the body and the tool hole has been marked out and spot where I want the tool to fit has been centre punched. Those fibre jaws that fit over the jaws of my big vise come in really handy.
Setting the job up to drill the hole for the tool.
A bit more drilling and I'll have this baby finished.
