[Amps] Winding rf chokes quickly - without a lathe

OK, I am on a roll.  Although I have 3 lathes, I am building a separate room 
/machine shop and my lathes are unavailable for the moment.  But, I wanted 
to wind a quick rf choke to test theory mentioned in the prior post.  Not 
wanting to wind one by hand, I found the desired core, which was tapped at 
one end.  Looking in my standoff drawer, I found a 3/8" diameter standoff 
with a stud on one end - which fit into the proposed rf choke.

Put the standoff into a cordless drill sitting on the floor, and holding the 
drill in one hand I used my thumb to control placement of the wire.  Just a 
short time later, I had a nice looking solenoid rf choke, neatly wound. 
Whole process, from idea to rf choke, took about 5 minutes.
