Howdy, all!
	I'm remaking the "big end bearings" for my Stuart Swan steam 
engine. These are bronze split bushings which are machined all over and 
the final operation involves clamping them to a mandrel to turn the o.d.
	Well, naturally the mandrel I turned for the job was too close to 
the right dimension and the parts wouldn't clamp securely. I didn't want 
to make another mandrel, so I got out my best pair of tin snips and cut a 
strip of Kleenex, wrapped it onto the mandrel, clamped on the parts and 
away I went: .020" deep cuts: no problemo and I didn't mark up the 
finished i.d. either.

Well Ed, you just discovered an old machinists trick!  I don't smoke, but 
there is always a package of cigarete papers in my tool chest.  They make 
great temporary shims, thinner than most tissue.  If drills & reamers 
slip in a morse taper, a piece of computer paper will protect the bore, 
and resist the slipping.  Most paper is between .003" and .004".
