|Some less fortunate people need
to build their models in a broom cabinet that doubles as a makeshift
workshop. I built a small workshop in my basement and kept upgrading it.
The lathe and the Rotwerk vertical mill turned out to be the most
valuable machines. By now, both have been replaced by larger ones.

|After a while, one keeps adding
useful machine accessories, e.g. the digital calipers that I later
equipped my mill and lathe with and that made machining so much easier.
To the lathe, I also added a tumbler gear for changing the direction of
By now, I have reached my ultimate goal -- upgrading both machines to
CNC. Details can be found under "Projects".
