Normal fiddling is on hold while I actually make some parts on the lathe.

These holes could let chips get into the electrics. This is not the lathe's fault – it came with a sheet metal shield that would have covered these but I decided I didn't need it on my custom bench.

I doubt actual experts would approve, but it works for now.

Tapping 1/4UNC-20.

The first part, as far as I can take it for now. Once the carriage is working I can face it.
