Absolutely.. and on a side note i'm often amazed by how i can come to ATS regularly for years and still discover posters who have been here for years
who i somehow have managed not to see posting stuff i find fascinating
I wonder if the tapered hole is a product of not using a 'boring stone,' but instead using sand and a stick to create the hole. As the hole bored
deeper, the sand would remove both stone and wood, making the wooden tip smaller as progress was made, created a tapered, conical hole as seen
Just a thought...
