So what do all these "gizzies" do? |
||||
|
1.) Index Gear provides rotational symmetry positions. |
|||
|
2.) Protractor provides the necessary facet angles. |
|||
|
3.) The mast head screw privides height adjustment |
|||
|
4.) The lap provides the cutting power. |
|||
|
The Index Gear is locked on to a single setting position, and the lap will then cut a flat directly accross from the indicated position. Once a set of cuts is completed the stone will show the resultant symmetry. Index positions are shown in BLUE and the resultant cut is outlined in RED. |
