Re: Bone turning 101.

Curtis,
In the great video you made - showing us your various steps - you made mention to be sure to mask up and not breath the "bonedust" - as you touched a pile of it.
Have you thought about "recycling" it?  Take a big pile of it, fold it into some epoxy, and pack it into a mold.  Then when the epoxy is cured, "slice it & dice it" as needed.  If you make the mold in a cylinder shape you will be several steps ahead of the game.
Just my 3ยข worth.

Thank you Birgitte.

I will save this idea for latter research.  Playing around with acid? 

My fear is the acid (much like boiling the bone.)    Will weaken the bone and make it un-useable.
I have Cola at home, It couldn't hurt to try this idea, I can see how it effects the bone. 

My goal is the bend the bone (flatten it) so I can use it. If the bone looses its properties and becomes soft or brittle, or badly stained, I cant use it.

My hope is by the use of ??? I can make the bone, or put into a plastic state where it can be flattened, and latter it will retain its original hardness and luster, it my goal.

I am hoping the ammonia will do this. and after flat, My hope is the ammonia will evaporate and leave the bone strong and solid/ usable for turning. 

Have a good day.

You can soften bone by soaking in hydrochloric acid. Also Cola, but I suspect that the tannins(?) in Cola would discolour the bone.
By soaking the bone in an acid, you are removing the inorganic material from the bone, and it might sort of de-nature it, 
it might not 'work' in the same way?

So far the only ways that I can flatten out a bone is to cut and  the sand the bone.

I have also found if I use carpet tape, (thin double sided tape) I mount a flat side of the bone (or bones), onto a solid Alum bar, and then sand the parts true. So I can get a number of disks all the same  thickness and true to each-other. making it much better for glue up. (and it helps me keep my fingers form getting sanded/burned while sanding small parts.)
I use a 12" circler sanding disk for this process, the bar I use is 1 1/2"x 1 1/4"x 14" long. I can mount 8-12 bone disks on to this bar, This trick works well for me.

SIDE Note.
Mounting onto an Alum. bar.   I have not tried this yet, although I have read about it and I know Mike P. has used this idea...

By using blue painters tape.  you can stick the tape on the bar, and then using CA  glue and accelerator you can,  glue the tape's back side to  another, blue painters tape.
the two tapes are mounted onto the bar and part. the glue hold the two tapes together. The benefit of using this method, is EASY clean up, the tape holds the work in place, but will easy to remove from both the bar and the part.  

I hope to try this method out for my self latter?

If Anyone can find a way to make bone soft enough to bend...   I would very much like to hear about it.

I just read about bending Ivory, they give two methods, one hot water. (dose not work for bone.) and the other using Ammonia. (un-known if it will work.)  
Perhaps Ammonia and bone in a pressure pot??? and some flat plates that can to clamped together, to flatten out the bone?  NOW the notes did not say if the liquid or gas is what effects the ivory.   It looks like this will be something that I need to try?

That's all that I have on this topic, at this time. ;-)

Take care.

sorry Curtis I had to say it.

All that I can tell you is that Vinegar DOSE NOT. after soaking some bone in Vinegar for over a month, it did break down the bone some and made a slimy mess, but the bone was not any softer... So strike one on this count.  ;-)

I read about flattening horn and bone. the author said steam will soften the hone and bone to make them pliable. steam dose work on horn, but It did not work with the bone I tried...  
NO other ideas on this point so far. Just wanted to let you all know what Ive read and tried my self.

Does anyone know if there is anything that will make bone rubbery?  I know an eggshell gets rubbery in vinegar.  Then each slab could be pressed flat and cured then worked.  Merry New Years

Mike OK

Yes I do. but I found that there is a small problem using this method. Bone is very hard, the bandsaw blade once it gets dull tends to wander.  by hand I can adjust to the wander, the fence cannot do that, NOW I know that I can adjust for the wander... but it more work for me to adjust... I dont think it will be any easer for me ...

I know that there are other ways to get the job done, I just need to figure what way works best for me.  I will try the fence again. 
I was thinking of trying an jig saw mounted under a board. This method may let me cut the bone on only one side, so I could quarter it as Mac. suggested.  Perhaps just using the "OLD School" approach and just use a hand saw might be just as easy?

Its a  trial and error process. I will keep trying. and let you know what I find out.

Have a good night.

Happy New Year!

Curtis do you have a band saw w/fence?
Push sticks and a good band saw can split a lot of material safely.

Good morning everyone.

Mac. You are right If I cut into smaller segments It would give me less waist. but the question is how to do that?  
cutting the bone in half is pretty easy to do with the band saw. how would you cut a round bone into thirds safely ?
I did not go into the cutting much, but for smaller bones I hot melt glue into a piece of wood so I do not have to get my figures close to the sawblade.  I guess if I hot melt the bone onto a block of wood, if made small enough I could cut on the edges (cutting into the center, as if it was standing in the edge.)  I think I will try that, the next time.
Thanks for the suggestion, Mac

Have a good day.

see you all latter.

Curtis,
EXCELLENT Video!  Great close-ups when needed and you spoke very clearly and at a good pace. Very easy to understand! 
You answered all the questions I asked earlier - showing them in the video.  This made it all "come together" and I completely understand your process. 
Regarding getting more "disks" out of your pieces of bone.  Have you given thought to cutting the sections of bone into thirds or quarters - vs cutting the bone in half lengthwise?   That could give you more efficient use of the material.
Happy New Year.
Mac

Hello Everyone.  
Today I was able to make another video for you all.  Bill posted it to his You-tube page for me. (so we could Show the group the video.)

This is just an over view. I would like to do another video latter. but I thought this one would be good enough to start with. I tried to cover most of the points, on how I work with bone.

Please let me know what you think?

I am finding bone to be a fun product to work with.  
I hope other with in our group will as well,  in the future. 

C.A.G.
