Just bought a small manual surface grinder and am confused by the
different types of indexers available. Could someone out there explain
the pros and cons of spin indexers, collet fixtures, harig grind-all's, etc?

Thanks for any help.

Spin indexers will allow indexing to selectable angles and rotating the part
for a poor-man's-cylindrical-grinder. The likes of the Harig grind-all will
allow the part to be held off centre for grinding radii. R.J.Newbould's
indexer will be similar, but more accurate.


I currently use a cheap 5C spin indexer when I need it.
