I was doing some cleaning and straightening in my shop today and came across some older bushings. Some still had CA on them and I put them in a jar with acetone, let them set for several hours, and then cleaned them off. They were noticeably worn after getting the CA off. I remembered reading on this forum a couple of years ago to regard bushings as consumables, and I did.
I then compared them to newer ones purchased about 12 to 15 months ago. I noticed a huge difference!
The ones that I purchased in the last 12 to 15 months and used - still have most of the dark gray/black finish on them, while the ones from when I started and even those used until May/June of 2007 are very worn from sanding.
In July of last year, I started using the mandrel-less (no-mandrel / between centers turning) I have not worn a single bushing and most have little to no sanding marks on the bushings. So for me, I don't have to consider bushings as consumables anymore - or at least the consumable rate was cut by huge amount.
Another advantage to the the mandrel-less turning - in addition to the others.
