I've never used the ceramic blocks in my Shopsmith BS. Everyone on the Shopsmith forum raves about them and says that with dual upper and lower bearings, nothing else is needed. I was toying with maybe getting the Carter set, but others have said the ceramic blocks perform just as well. $11.00 vs over $200 for both Carter sets. It's really a no brainer for this old cheapskate.
However, I'm still limping along with oil soaked oak blocks. I did put in the dual bearings, though.
