What I have turned on my cheap throw away Grizzly lathe.

for those who may be interested, that much can be done with even the
cheapest of lathes.

All the round parts were turned on Grizzly's hobby lathe ($44.95) 6 inch
swing, 24 inch between centers. that uses a 1/2 inch drill motor for the
head. (Use your own drill motor)

Just to show that it can be done.
