I have a thread on Prim Skills about ABO drilling.
Now there is not much out there about Abo drilling
let alone turning.
I'm a primitive guy so I made what I think an Abo lathe
might be like.
The abo drilling I illistrate on Skills requires two hands
while my lathe only one. The oak shaft and berings are
not even worn in yet, although the little sucker spins
prettier than a Dervish.
I have a vid of the very first action. PM if you want a copy.

I saw that somewhere before, really good working model.

Thanks bow,
If you can point me to where you saw anything similar,
Please do. Especially the bannerstone.
Thanks Zuma

It works aewsome in that vid zuma im definitely building one probably about the same size for my knife handles thanks for emailing me that

Glad you got the file Tyke.
It does work pretty good. With a 13 inch stroke, 10 revolutions a strokes
and 48-50 strokes in per minuet, equals about 500 rpm,
Improvement on bearings and shaft keepers are needed. Mostly keepers.
I was thinking something like this could or would have been used in bead manufacture. I also want to try fixing one string end to a sapling of the right
flex to see if I can make it work without the bow. Just pulling on the end of the string and see if I can get the tree to pull it back.
String slip is going to be your biggest problem imo Tyke.
But with trying different strings and bigger weights
all these type things can be overcome I am sure.

That's awesome zuma.. I seen a bow drill fire starter they drilled a hole in the spindle, then they ran the string through the hole before running it around the spindle I think this was done to help keep the string from slipping. Just thought I'd mention it maybe it'll help you. Ed

No banner stone, and a metal cutting tool, but this is pretty neat all the same:

Thanks for the tip Ed.
I will check out the vid soon Jackson. thanks.
I tried out the tree branch to return the string. It worked real well except
for a little bobble at the end of the return. This I think the bobble is caused
by the all the other branches springing back and forth.
I think that would be eliminated if there was just one single branch or sapling.
Next I think I will try a weight hanging down over the branch. A stable branch.

I tried a leather shoelace out on the lathe to be more ABO.
It worked very well until it snapped.
I did a lot of turning with that lace to be honest.
I was turning a piece of soapstone and really smoking the lathe.
Thing were going along ok shaping a bead until the spindle the
bead was wedged on failed. It was just a thin soft wood skewer.
I was able to round a portion of the bead.

A pole lathe would be better as you could use both hands. Cool, thanks.

Stick,
I'm all ears. How does it work and is it potentially ABO?
I think most of these difficult operations were accomplished
in the past by two or more people.
My concentration is mostly about the winged bannerstones
being more suited to drilling and spinning shafts than hunting stones.
Unlike the bow drill the reversal of the bow or limb lathe is not to
cool since the rotation reverses making contact with the chisel tool
dubious, not to mention amplifying the true-ness of the shaft and bearings.
I can't think of a way besides wind or water to get mono directional movement.
Course I don't think about it untill times like this. lol

Zuma a pole lathe, or spring pole lathe, is basically a half bow above the lathe, attached to something solid, tree, or a cross bar. the string is passed down to the work piece, and wrapped around it once, and then down to a foot pedal. Or the opposite direction, of from the pedal up to the half bow, and looped over the knock. Anyway, you just step on the foot pedal, and it turns the stock, and let your foot up, and it spins in the opposite direction, so you can only use the gouge, or other chisel, intermittently, as it spins one way, and then the other, but it has been in use for quite a long time. The bow lathe has been in use for quite a bit longer, and is still in use, as can be seen, in the video, the advantage of a pole lathe, is you can use both hands, the disadvantage, is it is bigger, and not as portable as a bow lathe, and takes up a bit more room. And requires you to build a solid frame for it, and the foot pedal set up. But it is super simple, and the frame is not difficult to build. Just Google pole lathe, or spring pole lathe, and you can see it's pro and cons, as compared to the bow drill. Thanks for sharing the pictures, that is a cool and simple set up. Obviously the guy in the picture didn't have any problems adapting to it's use, and is doing quite well with it. ;)

The vid was way cool. The operator was very talented. Thanks Jackson

Wayne thank you for the neat explanation. For some reason I had a vertical type lathe in my mind. LOL
