my apologies to you widow man , I misread your last post . I thought you had asked if it" was" my idea , not" what" was the idea . the statement or information was shared on another forum, long ago by Roger Snow . it was basically to insert a certain length of rod into the drill hole and site off of it . I can not remember how long the rod is suppose to be . it might seem like a strange thing to do , but I trust means and methods by those who have advanced . like I said I never found my self in such a spot to try such a thing . I see you have changed the picture at the top of this thread . no offence to you but I liked the first picture better . the new picture says the post was edited for a better angle and no false > . it appears to me that the second photo is shot in the sunshine , from the looks of your rock whatever it is, it is very old IMO. very old stuff does a lot better if you take the pictures on an overcast day, indirect light , not with the sun shinning on it ." sun shine and shadows" ,,,, that is for another topic cause my fingers cant type that much .
if I cant find the old post from a long ago forum maybe you could just ask Rog if you are interested, he is a member on treasure net .
