Bone points
Sep 7th, 2010 at 11:13pm
 
  I just made my first bone point today from a piece of deer leg bone I found in the woods.  I just sanded it out on a belt sander, it's fairly intricate notching and about 3in. long, it only took me about 10min. so I was surprised.  I haven't cooked it yet and that's why I'm posting this.  I would really like to make them without using a belt sander, but I'm not sure how.  I would guess you would use a piece of sandstone but I tried it and it was excrutiatingly slow, I could make about 3 flint ones in the time it would take or a slate one.  So my questions are:  What is the Abo method of making bone points?  How do you haft them, I heard mention of hide glue somewhere, is that made from rawhide?  To temper a bone point I read a while back that you put it in a coffee can and cook it...at what temperature is best and how long?

  Thanks, I have to go out and get a cow femur and make some knives as soon as possible.

I always boil the bones before I start work on them, some have bacteria that will happily grow in your lungs if you breath the dust.  If you use the chips from your flint knapping, bone works pretty easy.  Not quick, but not real difficult either.  Doing the intricate carving is really slow with stone tools but it is not hard to learn how.  I usually cheat and use power tools or at least steel tools.  Bill

  I bleached mine and then stored it in a box indoors, I probably shouldn't use bleach though, the outside layer was a little soft because of that but below it it was good and hard still.  I did breathe a little dust as I was only wearing a ripped t-shirt for a dust mask, I won't be doing that again though.  I made up a bunch more from the scraps of the first as I had just a small bone to work with and made some points suitable for small arrows or blowdarts, no more than about an in and a half long at biggest and no more than 3/4 in. wide for the biggest.  I lugged the belt sander outside though to do it as I didn't want to stink up the workshop and breathe too much dust.  I can make an arrowhead/sperhead in about 10min. on that thing, it isn't half bad.  I don't seem to be able to get them very sharp though, for example they don't quite cut through a piece of paper laid flat on a sheet of cardboard on a desk, I tried sharpening with fine sandpaper, then an emery stone and still can't get them any sharper...

The bleach was actually a good thing, it is a good disinfectant.  It does break down the bone unless you wash and scrub all of it off or neautrulize it.  If you still have some in the bone, that is probably why you can't get it sharp.  You also have to use a slightly different angle than what you would use on a steel blade.  And you need to cook it to harden it.  Putting it in a coffee can over a small fire until they turn slightly tan will do it, dark tan makes them crumbly.  It stinks, so be warned.  That is why I boil mine for 20 minutes, it hardens them without the danger of destroying them.  Boiling also helps remove the squishy parts, they come right off with steel wool or a scraper.  Bill

  Ohhhhh so boiling it does work.  I was trying an experiment with them the other day involving a barbecue lighter, I was just taking the lighter and heating the edges to a brown/goldenbrown and trying to sharpen them.  That is how a good sword is made, just the edge tempered so that the rest of the sword does not become brittle.  Needless to say it didn't work.  I wonder though if there is some way to do this, perhaps dipping the edges into a vat of boiling oil or water...  I will definitely try boiling one tomorrow, does it smell bad to boil it?

  I'm told a un-flavored cow bone from a pet supply store works well, haven't tried it yet, I just made the points from an old deer bone I found on the beach.  What you want is a femur because of the flat sides and thickness and try and get as straight a one as possible.

I prefer cow bone because it is thicker and fairly easy fo me to get.  A grinder and a belt sander help if you have lots of bone to remove.  Watch the dust!  It can kill you!  It will stink if you use power tools, it will smell sort of like burned hair.  The pet shop bones still have the marrow in them, you will need to get that out. 

I use a hand saw to cut the ends off, then scrape out the fine bone that held the marrow.  I look down inside the bone and check where the thick spots are.  I use my saw to cut it into strips, I work the strips down to what I want.  A vice helps as does a wire brush.  Bill

  Cool, might be a while before I can get a hold of a cowbone though darnit, but I will be looking for alternate sources to the pet shop as there isn't one near me, I have to drive to the city.

Try a local butcher shop.  Lots of times they throw out the parts of the bone that you want.  Bill

Just curious, what about the dust is so harmful?

Hummm... I made some bone points out if some crunched up shards of deer long bones (coyotes crunched them for the marrow, I think), and filed them down into points with my trusty, if rather rusty, hand file and sometimes the driveway.  It took awhile... I haven't put them on arrows yet, but I really like them.  I didn't really do anything to disinfect them though, so I'm really hoping bacteria arn't happily growing in my lungs...

I've gotta try making slate ones next, they look fun.

Usually, bacteria.  Usually, if it can grow on bone or horn or antler, it can grow on you, if you give it the chance.  Just because you work with any of the above does not mean it will, just that your chances are better.  Bill

Well that's good to know. I'm sure I would have breathed that stuff in all day long had I made my own by now.
