Helpful Hint On Drilled Holes and Carving By Hand, Stone and Power Tool

[monsterrack]

I wont to show what a stone drilled hole looks like and also what carving lines by stone looks against power tool works. The 1st photo is of a hole in bone that was drilled by a stone drill 1st let me point out how the bone which is soft angles all the way down to the very inside of the bone. Next notice the tapered look to it and also stone will make a polish sometimes. These 2 photos shows what a hole in bone would look like when a power tool is used an also trying to copy what stone will do. 1st notice the straight down section at the bottom of the hole. That is where the drill bit broke through at the last part of drilling. Also you can see the walls of the hole have not got the smoothness of the way the stone did. Also you can see where the bit made marks outside and inside the hole. This last 2 photos are just a straight down drilled hole by a power tool. Stevie Wonder could see that this is not right, but yet people get taken everyday with holes in repro's like this.

This next section is on what hand carving marks look like and what a power tool mark look like. This photo is what marks look like when done by hand and with a stone flake. Notice all the small cuts in the bone and the lines are not very straight. The human hand can not go in a straight line when doing this type of work, you will always off track. Also notice at the end of the lines the lines let up due to you picking up with your hand. This photo is of lines made by a power tool. Notice the lines are straighter and down in the bottom of the cut you will see small lines that run through the cut. This is what is called tool marks, made by a rotary cutting tool and also you can see where the bit dipped now an then. This photo is of a power cut and a stone cut side by side. You should really be able to see how the power cut, which is almost the same width stands out from the stone cut. If you buy an artifact or not, I would advise all to get a good eye piece scope. They are well worth it just to be able to look at what you find. These photo were taken with my phone and a $10 lens from wal-mart. I hope this helps and ask any questions, I'll be glad to help you.

Very informative! Thanks for posting about it.

I've often wondered how (with a whole lot of patience) NAs drilled the holes in pendants and banner stones. Have been told that they probably used some sort of grit when drilling the holes in stone. Thanks for the insight on the cut marks on the bone. I'm always reading when they find bones at kill sites of the cut marks made with blades and stone knives which they usually they say were made by man.

This is good stuff to know. Thanks.

I was going to ask about drilled holes! I want to share some up close pics and get some feedback...supposedly an 1890's ceremonial piece or more likely tourist piece. Plains Indians. Is this 1890's style or later? Thanks.

Bad pic...but you can see the drill ridges...seems more modern but not as modern as a mortar bit.

I can't open your photo ?

Huh...it pops up for me on the app...Anyone else having issues? I'm not sure I know how to rectify that monsterrack.

Another try at the pic...

The horsetail, sinew, turkey feather remains are all real...I just think it was either for ceremonic purposes or tourism...my wife bought it for me but I've had suspicions that it isn't what they sold it to her as. They claim 1890's...ceremonial.

I have not ever seen an item like that, not sure what it would have been used for. The ridges in the hole look odd almost like it was molded that way. I can say it was not drilled from the photo. JMO

It almost looks like a stepped bit used for cutting out metal. Definitely a conically shaped hole. I was thinking old, 1890's or so, but probably for tourism/memorabilia. Not sure but others similar to it can be found on the web. I appreciate it.

What do you think?
