Too bad it was so slow...

"However, the 20tpi leadscrews and small stepper motors resulted in
such slow movement that it was faster to do them by hand. "

Of course, if the time to complete them is not an issue and it doesn't
require constant babysitting, then it's still an advantage - you can
do other stuff and only deal with it for a minute between each run.  A
faster stepper driver (acceleration, etc) would probably speed things
up quite a bit anyway.
