Another stupid pot question...

[Larry Leitner]

Now that I have realized that pots + knobs are the most expensive part of 
making a synth.  I have narrowed my search for pots down using the 
criteria: rotational life, physical size, price, and resistance.

Except I've noticed one thing.  Most of the shafts on the pots are 
completely cylindrical or at a minimum have a screwdriver slot on the 
top.

How do I attach the knobs?

Don't tell me I have to pull out a dremel tool and slot the shafts.  This 
would certainly damage the wipers.

Some knobs say they have a positive grip (?? from memory) Does this mean 
it has teeth that dig into the shaft so the shaft can be cylindrical?
I don't really think a knob with a set screw would work either.
