I am boring out a welded sprocket and hub to use as a drillpress stop collar. No great accuracy needed. It is old and rusty. it kept walking out of the chuck so I used a single wrap of brown paper bag between the work and the jaws.
This kept it in place and let me complete the job. I had thought of using a boring head in a vertical mill to enlarge the bore by about 1/2 inch. I do not care about any loss of accuracy due to the paper for this job. Also the welding job is a little off so the gear wobbles if the hub is running true.
I did read here not to us masking tape since the glue will melt and slip. I did not actually use brown paper since I had one of those nonwoven butt wipes nearby. It had dried out and felt pretty much like paper. I think it may be paper with some plastic or just paper. I do not think a kitchen paper towel would be enough.
Same idea as blotters for a grinding wheel.
