Hi Hermit,

Theres some info regarding accuracy 1/2 way down the page here:

http://easyweb.easynet.co.uk/~chrish/eqnotes.htm

Its not just all PE because one turn of the worm isn't a full turn of the
main wheel so its not 100% regular PEC if you know what I mean? ie: there
maybe some minor irregularities in various parts on the main wheel/teeth
which isn't subject to PE which is one turn of the worm - having trouble
describing this :-)

Quoting J&S :



How much does this help with periodic error, not just fit. And would finer
grades help too?
