The fly cutter further along, cover being bored. This time it is mounted on a short arbor held in the new milling spindle on the lathe. Since it's likely to spend a fair amount of its lifetime there, this is as good a way to mount it for machining as there can be.

vtsteam:
The new fly cutter at work. Here it is truing up the inside vertical face of the table extensions I had just cast, mounted on the boring table.

vtsteam:
The lathe boring table and clamping extensions mounted, being trued. After the left vertical face was trued, the whole table an extensions were surfaced again to make them flat and even. Then the right vertical extension face was milled.

vtsteam:
One of the things I realized in all of this was that there were three ways to adjust a Z axis in horizontal milling machines. The first is to have a knee or slide with the work on it. The second, less common way is to have the mill head adjustable in the Z dimension. Gingery's horizontal mill uses this method.

The third method which I had here developed for my lathe was to make a set of adjustable fly cutters to provide adjustment range up to the center height of the lathe These could be mounted on an arbor between centers, or a stub fly cutter. However this was mainly to be an intermediate stage in producing a vertical slide type, and in fact a rotary table version of that so I could mill the Tesla ports.So the next stage was casting the vertical ways and slides, which would ride on the boring and milling table as an accessory.

I would now use the milling table to finish those parts instead of laboriously filing and scraping them into bearing. I decided also that maybe I could re-use the library of slide patterns I'd already created in making the lathe. So I standardized on their dimensions, and realized I could add removable adapters to the patterns where they needed to be different than what was required by the lathe.

Here is one of the adapter pattern pieces being glued up.

And here it is attached to the lathe cross slide pattern. It fills a hole where a steel pivot rod was required on the lathe, and builds up the side's thickness. I also added additional width to the slide land bearing -- with a strip of wood.
