Hey All..

I had tested the motor I recieved from Herbach   ( the 8.00$ one  part 
number TM92MTR2041/c )  and found it to lock at 90 degree sectors    now 
heres the weird part...  it will do this when there is no load on the 
shaft...   I built the spark gap and mounted the rotor and now for the bad 
news...   it does as Scott sez   it locks at multiple points around the 
cycle...  it no longer locks at 90 degree increments..  :(       but with 
enuf practice and setting it up at a specific point it will end up at the 
proper spot.....

sooo..  I took it to work to mill some flats on the rotor and to my 
suprize...  the rotor consists of a steel shaft,   an aluminum core with a 
cylindrical solid magnet   nope  not split  not multiple parts  but a 
single magnet...  okayy..  I still went and put it on the mill and tried to 
mill flats on it...   guess what...  this "magnet" is harder than stainless 
steel and will roll over the cutting edges of our best 4 flute milling 
bits..   so much for milling flats...

if you dont mind pre-positioning the rotor before turning it on, then this 
is a good motor for the money    but its not exactly what we need 
....    sorry for getting everyones hopes up...

live n learn....     but hey  its still 1800   rock solid rpm   :)
