Dial Indicator Attachment

One more hand safety tip I feel needs mentioned.
I've seen countless machinists do this, and recently even watched a few of those instruct-able vids published by folks who have published dozens of how to videos.
Where the machinist places a small swatch of Emory cloth or scotchbrite on the tip of his finger then inserts it into the bore of a spinning cylinder to polish the bore
I was even guilty of doing this twice first and last at the same time early on while teaching myself how to use a lathe. The bore caught the swatch and twisted my finger around fortunately it didn't rip my finger off or even break or dislocate a bone all it did was rip skin and meat loose from the bone leaving my nail on the underside of my finger. I was able to twist the skin and nail back in place then wrapped it with gauze and made a splint then taped it up real good.
my finger had that stinging needle feeling for quite a while the nail later came off but grew back and everything healed up just fine
That happened close to 50 years ago and to this day when the inside of a cylinder needs dressing I use a split wooden dowel rod with a swatch placed in the slot my fingers or hands do not go inside of a spinning cylinder.
