My little 7" x 10" mini lathe was starting to get despondent from lack of not enough use, so in order to cheer it up I machined a ships cannon on it. Kind of small, but that is OK because it does not take up much display space. The tie rods and eye bolts are all size #o-80, which for me requires a 10 power magnifying glass to examine the threads. They were just fine.
Actually I use that little lathe quite often. There are some things it does very well. Holding and threading that size fasteners is one of them.
