[QUOTE="Dihusky, post: 537629, member: 10304"] No not at all, they are a very accurate machine, the problems I encounter are positioning the stone to see the facets when I'm cutting, particularly when doing final polish. The way the large protractor places the quill, I fins I'm either stretching up or craned over in a awkward way to see the facet clearly, with the bottom end of the protractor in your ribs, and constantly adjusting my lamp, maybe it's just me. The other thing I found is their sensitivity to lap weight, the cutting table is offset from it's support mast, so with a heavy typemetal or cast iron lap it can tilt fractionally and throw the facet out, the same can happen if you put too much pressure on a stone. For me, it's also very inflexible when working the table, if the previous facets are slightly out, its hellisly difficult to push facets unless you rotate the quill and this can throw the whole table out if you're not spot on 90 degrees. Just my opinion and why I use the Hall 2000 extended, it gives me unlimited flexibility to find and work facets if I have to, particularly doing repair work, a friend of mine who does a fair bit of repair work also used the Hall 2000 extended and will not use anything else for this type of work.
