While I do agree that a machinist's lathe would do the work better, I bought
by wood midi-lathe just for this kind of work on plastic and brass. You
just need a steady hand and a sharp cutting chisel to make the motor spindle
piece or cut down the plastic wheel. No problem. For this level of problem,
only difference in the machines is how the tool is held.

I have been told by a turning machinist that a traditional wood lathes work
in a horizontal spin way
so won't fit the task, except more complex wood lathes out there.
Always an option to a CNC drilling machine is having linear movement in the
base table.
If so the traditional drilling method works according with this picture
http://www.grizzly.com/products/Mill-Drill-Milling-Machine-25/G1005ZAnybody searching the article look for item # G1005Z
afaik Grizzly is a multilingual site.
An alternative to the above pictured is a sliding a table can be got
separatedly as here:
G5757 Compound Slide Table
http://www.grizzly.com/products/Compound-Slide-Table/G5757Sorry if the above shows up as stuff from the cavern times , let's say
analog world
It's not so appropiate for PCBs
as would be a Dremel but it works for other force-demanding work either,
kinda 'light milling'
Those tables coming are far cheaper than the pictured bundle above, both
drill and table.
Please if anybody already have bought it and have complaints about
registering/precision factor with the compound slide table please advise
Best,
Samuel

You might need a lathe, but you don't need a metal lathe.
A wood lathe would do.
On the issue of the impeller at the bottom (clever repurposing there), would
any angling of the blades help with startup or pressure?
Could you build a sort of Archimedes screw in the bottom section?
