I have an "air bearing" but I think the advert needed to say "air quill":

but I prefer this one:

The trusty old "Spindexer" can do pretty well too:

The air quill has a very low co-efficient of friction andwill or may "get away" from you if you are not careful - particularly if the spindle is tilted.

I'd suggest that anyone who hasn't tried it, give the "Spindexer" a "go" as it is very "forgiving" and if you have one it will cost you nothing to try.

The spindle-to-bore fit in my "Spindexer" is very good.

An air (or other type of) quill can be used quite successfully on a surface grinder with a "saucer" wheel. A tool and cutter grinder would be nicer to have but is not essential.
