Re: Holiday bone turning.

[M.W.Foscue]

Curtis,

Got it.  The extra pics helped.

How did you secure (you state "locked") the 1/4" drill bit into the axis of the 1" router bit that you welded into the center of a (?" inside diameter) diamond hole saw. 

Ingenious device to use to make these "Bone quarters".

Thanks again.

Mac

Hello again Mac.

The process is very simple. I cut the bone in half. (using my band saw) I put the flat down on my drill press, the drill the center hole, (very much like drilling with a hole saw.) I drill down cutting the round and flat of side one. then I flip the bone over and using the same pilot hole I drill down to the inside part of the bone this cuts the curvature out from the bone.  

If all goes well I am left with a bone disk still inside the bone, all I do then is cut out the bone disk. (which you can see in the photos is almost gone.) there is some light sanding of the disk to get it flat and ready for glue up.

I wouldn't mind making a video, but honestly is would be pretty boring.  I think these photo should work at least for the time being.

Now as far as getting the bone white. Hydrogen peroxide dose the trick. (or you can buy bones already bleached (with the H2,O2.) the work goes quicker.

The one fustigating part about bone. is its not all the same thickness, Leg bone work best. and What I have read, Draft horse and Oxen have the best/densest bones. What I can tell you is Smaller dog (chow bone) seem to work best for me, I can see what I'm buying, they are smaller so there is less surprises on the thickness of the bone.  and since they are smaller the price is cheaper to buy.

New bone is very oily, It will have to be left to dry out, or peroxide removes much of the oil.

I've been given horse bone, This bone was very big on the outside, but the bone was mainly merrow and very little usable bone.

I also found out that if I cut the bone into disks and then soak them, I get more useable bone quicker then If I soak the bone first.

As you can see in the photo of the handle, there is not always a all white surface. (not all bone has the same color.)

Sorry I don't want to write a book at this time. ;-)

More questions please I will answer as much as I can. but not tonight. 

Have a Merry Christmas everyone.

Curtis,

Thanks for the photos.  By chance do you have one or two that show how you are actually drilling into the bone?  The pics are more of a "before" and "after".  I'm maybe a bit dense - not getting how you drill/route into a curved piece of bone and end up with a flat/thin (quarter-size diameter & a nickle thick) disk of bone.  I get that the 1/4" router bit you have welded(?) into the 1" hole saw creates the hole in the center.  What I don't see/get is how you from a piece of "curved" bone to a flat "coin" of bone.

Thanks.

Mac

Hey Mac.

Merry Christmas.

Yes I do.

Its a homemade barrel trimer of sorts.  I used a 1" router bit (one with a barring) removed the barring and drilled out the center to 1/4" for a drill bit to be locked in place. then I wielded a diamond hole saw on the out side for the router bit.  I used a nickel as a spacer between the router bit and the diamond hole saw. this way the saw cuts slightly deeper then the router bit.

Here are some photos.

I have been thinking about buying a ultra shear pen trimmer.https://www.woodpeck.com/ultra-shear-pen-mill-inserts.html  Its smaller which may make it easer to cut bone out form its original form. with the homemade one I cut out 1" disks, and the ultra... cuts 3/4"

Working with bone on the Legacy is pretty neat. the cuts do not need any sanding. I take light cuts and the router bits do not show any signs of ware.  Bone takes a very fine detail. its a Neat material to work with, that most people do not do. And  it looks like ivory when done. 

I am having a lot of fun working with it.  My process is still very much in the experimental stages.

I may find better ways of working with bone, but so far this process has worked out pretty good for me... 

If anyone has any incites or suggestions, Please let me know.

Our group was formed for things like this.  "How can I make?" with my Legacy Ornamental mill.

It is only of MY Legacy originals.  Please feel free to try it too. The more people use it, the more we learn. ;-)

Have a good night.

Curtis,

Nice work!  Do you have a pic or two of how you manage to get those flat round "coin-like" sized pieces cut out from those "half-cylinder-like" (hollow core) pieces?

Merry Christmas to you and all our Group members!
