@trc65 and others have talked about carbide tipped live and dead centers. I've never heard of them, what is the advantage of the carbide over "plain" ones? Tony

I hadn't heard of them either, but in @rdabpenman response to my thread on mandrels:
https://woodbarter.com/threads/question-on-mandrels-etc.40139/page-2

The handout he attached showed carbide tipped centers. I assumed that the carbide tips would prevent galling/scarring from the rubbing/slipping of the bushings on the centers.

Note, this was just my assumption, but I assume I'm correct.:ponder:

Another assumption; I guessing that carbide tipped centers are primarily used in metal turning, hence their absence from the Woodturning supplier sites that I searched.

I bought a live center from these guys before I started making my own. They cater to metal working more so than wood turning. Here's a link to a Carbide Dead Center with an explanation of it's use. I just noticed it took me to Amazon, but if you search for Z Live Center, you will find their site, located in Orange County, or maybe very southern LA county, in Diamond Bar, Ca. . ... https://www.bing.com/shop?q=Z+Live+centers&FORM=SHOPPA&originIGUID=F55F0E3629D7418FB06051014BBC8978

I agree w/ Tim that it seems carbide live centers would only be needed in metalworking, not at all in woodworking.

Ive been using a carbide tip live center for pen turning. I haven't had the typical wear that happens with a standard live center. It lasts longer too. I bought two over a year ago and haven't seen the need to use the back up yet
