Salt River in the Superstitions is such a beautiful area .
I miss it at times .
Eagles soar the currents
the colors , the place is just so calming .
Help ya out on that Mirror gig
as soon as an Expert as well as another Troll , leaves this page .
The mirror's purpose is for reflecting sun light as the chipping is done .
to mimic the Sun rays by redirecting them during a time of day when it is not shining on the surface
to be chipped .
Testing as well , to find whether the chipping is imperceptible without direct sun rays on it .
if the chipping can be seen when the mirror is deflected , they try another surface to the one side or other until
a spot is found that the chipping is not perceptible without Sun Rays directly on it .
There's more to the formula then this .
such as angle of tool tip when chipping , depth of chip out as well .
Pretty cool technique
have you tried to duplicate it ?
