ok.. folks... i never claimed to be an artist’s lol
The picture on the right is what you would call "cutting an OUTSIDE corner" Everything in the picture with an x is what you want to KEEP. The circle represents the blade. You can set the blade at the depth shown run it in a straight line all the way through the stone. You can then run the other direction (other circle represented) in the direction show.. all the way through the stone.
It is OK for these two lines to cross because the points that they intersect and where the lines of the cut extend are at a point in the SCRAP of the stone. SCRAP being the part of the stone that is not considered your "Project" . you can basically cut the hell out of the scrap because it is just that.. scrap.
As you can see from the picture with a blade of about a half inch thick, you could make several passes in the direction shown and with some finishing touches and passes; you would have your finished project. EVERYTHING WITH AN X WOULD BE LEFT.
You could also flip the project, but being a huge piece of stone and running a computer program that makes the passes for you, its better just to make multiple passes rather than re-setting the entire piece of stone.
Ok... got that part...... now.. on to the next drawing on the RIGHT!!
This students is what we would call an INSIDE CORNER. Marked with an X are the surfaces we want to consider our finished project. Considering your lesson on the outside corner and how that is done, look at the circle in this drawing. By starting your saw into the stone and moving it in the direction of the inside corner if you continued you would end up cutting into part of what is to be your finished project... noted by the word BAD in both locations.
With this project being a very expensive piece of stone that will be going on a building, you do not want to do that.
Sooo... your only option is to make the multiple passes with your saw, BUT only cut into the stone a small distance in order to get your angles started. What you are left with is a big chunk of the middle that is still filled with stone. The only way to finish out the project in stone (and the tools i had available) is to cut and chizzle it out by hand.
In the above drawing i used a right angle profile to simplify things. But as in the piece on the building it had curves making it much more difficult.
If you cannot comprehend this by the pictures used and my explanation given.... I am either a lousy teacher... or YOU ARE A TOTAL DUMBASS!!! HAAAAAA
ROTFLMAO!!!
