This is probably already widely known - but I'll pass it along anyway.
If you have need for a temporary bushing for an alignment issue or some other need; and, you don't have an exact size available, but you do have something close, but under sized, here is a simple solution that works (sometimes).
Green "masking" tape is approximately .005" thick, so - a single wrap would yield an increase in diameter of approx. .010", and a half wrap would give a .005" dia. increase, with a .0025" offset (not much really).
Case in point: I had need for a bushing that measured .388" +/- .002" in diameter for a little job I had at home, and didn't want to go "visit" my lathe, which lives 20 miles away. I had some 3/8" (.373" o.d.) aluminum tube I could use, so with a "wrap" and a half, I was able to get the accuracy needed to finish the job.
Just a simple method that works in "semi" precision situations.
