A question for anyone who has made or has thot about making a rotary tool
shank, like for attaching cutoff wheels.
What is an easy to find material for making a rotary tool shank? I was
thinking maybe using some rivet. Whatever, the qualities of the metal rod
have to be something like this.
...Drillable metal, not extremely hard.
...Diameter exactly 1/8" quickly flaring to 3/16" or whatever at some point
(it can be cut).
To accuratly center the screw hole in the end of the shank, the unmade
shank can be inserted into a drill or rotary tool and spun against a
stationary drill bit.
Thanks in advance.
