[sdiy] Cutting rotary encoder shafts??

[The Peasant]

I've seen 3 kinds of official Dremel cut-off wheels, there is the basic 
composite one that's very prone to self-destruction, a better reinforced type 
for a little more money that works quite well, and a high quality diamond 
tipped metal blade as you describe. The best part about the cheap composite 
ones is that they wear down fairly quickly if you manage not to shatter them, 
and the resulting smaller size cut-off wheel can be very useful.

If anyone wants the official Dremel stock numbers for any of these types I can 
get them tommorrow at work.

Take care,
Doug
