Thats heaps different from how i do it :) but thats what i like about watching other do it. I saw one guy and he used nearly the exact same set up as me. Except I use extractors on all my machines so i dont wear a mask or pollute the enviro. I knew then he was unrelated :wink: :D

I dont think much of the Myhre book On Techniques and Concepts. Even though i was trained, i still couldnt work out some of the things illistrated in the book. (That and his weaving is Asian) There are better resources, even free on the net. The best book i read though (imo)was by Ropata Davis (i think) but unlike Myhre instead of focusing on the tools, it talks about things related to Maori. The form and quality of the objects and also methods of sale. Its worth a read if you can find/ borrow one. The carved Pare is also good.

From what i have seen there are alot of different styles of bone carving in NZ and even overseas. Many of the tools are the same but usually people develope their own ideas/ methods independly. There are specialised tools that have to run in perfect specs to even operate properly. Ie My friends machine runs at 1000 rpm he uses 80 grit paper, my machine runs at 3200 rpm so i have to use a softer paper 100 grit. Even then its twice as fast as his. It runs to fast. Getting all my tools to run at optimim is half the work.

B

Rainhawk, it's Amazing seeing all the different methods using different tools and ending up with basically the same end results. Usually people carve with what tools they have available which can be very different from person to person, country to country.
What is the name of the book you mentioned by Popata Davis it sounds really great.

i learned, through trial and error (lots of errors), that a good staining technique is a teabag soaked in white vinegar. i won't bore you with the chemistry, but vinegar stains calcium.

think easter eggs.

you can apply it with a brush, q-tip or any small applicator. tape off areas you don't want stained. if it's an indented area paint the edge with elmer's glue to seal that off. it will wash off.

R

I was told never EVER use tea or coffee stain because it will wash out!?! Do you know how long it holds for? I dont really stain but i usually use a god pigment that will take.

I read alot of books but i just liked Treasured Taonga on a personal level. Because it talks about being a struggling artist :) This is the only link i can find : http://bahai-library.com/bafa/d/davisr.htm

Thanks for digging this up! Great reading for an addicted Boner like me.

B

Yes, Thanks Rainhawk. I found a couple Used copies for sale for $362 so I won't be getting that just yet. Anyone have a copy they would loan out? Looks like a "End All" book

R

$362 LOL: rolf its not THAT good :lol:

Thanks to all who have contributed to this thread. I started a manta pendant yesterday, did some rough shaping outside with a belt sander. When I took the piece inside, my wife said it was stinkin' up the whole house and she made me put it in a ziplock bag :lol:

Bone seems like a cool material- strong, no grain issues, and polishes well. IF this turns out, I'll post a picture here.

So I made a bone manta ray pendant (yes, I know it's not very original) It turned out OK but the tail was off center, it was good practice - I love the way the bone polished up. Since I didn't plan on keeping it I thought I would experiment with a wood burner on it (is that allowed?) I tried to burn a tattoo style pattern on the ray and really jacked it up! :lol: I took some "before woodburner" pix but they didn't turn out, and the "after woodburner" pix are hideous, so no pix for you! :D

EDIT - I sanded off all the hideous woodburner markings (except the eyes) and now it's back to OK (not good, just OK)

That was fun. My next project will require a bigger piece of bone than I can get from the pretty white Petco bone I bought. If I get one of the "Giant beef bones, how do I clean it and make it purty & white? Can I throw it on the ant pile? :)

BD

get yourself a bone from a butcher and toss it into an ant pile. once it's been picked clean i think you could probly dunk it into a bucket o bleach so it can come out bright and white. at least that's what i would do.

Hi MadDogMike!

Happy to see you in this thread! Can't wait to see big bone carving!
Bleach and water boiled appears to be the right solution, but I'm not expert for that... Need help Benz! Mango! Rainhawk!

Don't use chlorine bleach! That is a major No-No. You need to clean as much of the meat off as you can with knives, metal brushes etc. Get as much or the marrow out too (push it out with a stick). You can boil it now. After boiling, remove any remaining meat and gack. You should then soak it in a wash of dish detergent (Dawn works well) and water to degrease it. This may take several days and some scrubbing. Once you have washed it completely and removed all of the soap, you should then soak it in 20 volume peroxide. This is not supermarket peroxide....you can get this stuff at a beauty supply store. It generally goes by the name of "developer" (hair bleach). Do not get cream developer! What you want is "clear developer" - it is like 7 bucks a gallon. Put this in a sturdy plastic container and let her soak for at least 48 hours if not longer. Keep the container somewhere cool and dark - heat and light deactivate the peroxide. Move the bone around and scrub it with a plastic vegetable brush to continue cleaning. Once it looks good, take it out and rinse it in water and set it somewhere clean to dry.

Now youz ready to carva da bona...

-G

MadDogMike, nice manta. Most scrimshaw work was scratched/etched into the bone then the lines were filled with India ink or anything dark and permanent.

Thanks very much guys! I love the wealth of knowledge on this board and the willingness to share it :)

B

T-Mango, Do you Have the book Treasured Taonga? If so would you mind bringing it down to the jam?

mdm,
sorry to give you wrong info, but glad gman was able to provide the correct answer. good luck. that manta is sure pretty.

bd

Benzart, I WISH I had that book... :(

This is fun, but challenging for me. For one thing you can't add material back if you take off too much like you can with clay :D

Still needs more polishing but I have a couple more questions;

If I don't want to drill a hole in his forehead to hang him as a pendant, what are my other options? Can I epoxy a ring to the back? I would have left a bone loop on the back but didn't have enough thickness.

Can I use a cloth wheel & polishing compound/rubbing compound or will that stain the bone?

EDIT - I just picked up a deer antler, does it carve just like bone?

Hey :)
I agree with this :
"Don't use chlorine bleach! That is a major No-No. You need to clean as much of the meat off as you can with knives, metal brushes etc. Get as much or the marrow out too (push it out with a stick). You can boil it now. After boiling, remove any remaining meat and gack. You should then soak it in a wash of dish detergent (Dawn works well) and water to degrease it. This may take several days and some scrubbing. Once you have washed it completely and removed all of the soap"

But then id concider it ready. If you did it properly, %50 of it would be pure white bone and some of it would be stained. I just dont believe in using any harsh chemicals. Not just for the enviro but because i have seen some chemicals weaken bone. I may be wrong GMAN may have more experence with chemicals.

MadDog : Stephen Mhyr's book shows how to laminate steel to bone
Deer antler is similar to beef bone but it can be porous, can also be better
You can polish but you need clear or wax white polish, not brown wood polish from a dremill pack.

I only liked that book because it inspired me on a personal level and it is full colour, there are obviously better books for carving instruction. I was lucky to have a peek at a book recently. It was by brian flintoff i think it was Taonga Puoro. I am not sure because i just had a browse. But had insane detail of making traditional instruments by hand. I need to get it

When I polish my bones I use white jeweler's rouge. The polishing compound fills all the little pores and makes for a nicer finish. I've also used the red rouge and it provides a nice contrast to show off the pores if that is the look you are going for. To each his own when it comes to da bone.

Yea rouge not rogue :wink: :lol:
Has anyone else see the book by flintoff? its similar to the myher book but has indepth detail, more techniques and different artifacts. They have a copy in the library here but its restricted i think.

I have it and it's well worth the $35 or so. It's beautifully produced, well researched (although I would have liked more historical examples) and has a CD in the back with recordings of the various instruments.

B

Rainhawk, Paipo, the book sounds great and especially if it's only 35$ but you forgot to TELL US THE NAME??? You guys are as bad as me, forgetting major stuff like that. :o :)

MadDogMike, sorry for the late reply on this, but did you solve your cord attachment problem on your moai carving? Depending on the thickness of your bone, you could do one of the following:


A) Create a tunnel. This takes concentration as it's really easy to go all the way through, which you don't want to do. Just attack the bone from both sides at a 30-45 degree angle until the holes meet. Make sure you have enough material for supporting the weight of the piece and get rid of any sharp edges so they don't cut your cord.


B) Hidden top-hole. This is easier to do. I tend to offset the top vertical hole so the thicker material is towards the back of the piece where all the weight will bare. The good thing about this is that you can compensate for a thin piece of bone by having the horizontal hole further away from the edge, giving you more material to carry the weight of the piece. Again, nix those sharp edges.

C) Bonded bone loop. I haven't done this yet, but I think it would work just fine. Create a bone loop with a flat base, this would insert into a channel on the back of your piece. Use a gel cyanoacrylate (super glue) to bond the loop to the piece. Just be careful as the bone will bond fairly quickly, so your working time is 1 or 2 seconds. Any excess glue can be tooled away.

I hope those suggestions help.

Rainhawk and TikiMango thanks very much for the suggestions, I need to finish that piece. TikiMango, the 4 braid cord is awesome, I may have to try that.

Malo 'e lelei,

I was wondering if anybody can give tips to making crisp clean inside sharp angle cuts in bone. Especially in tight holed areas. Like these for example:

The smallest bur piece I have still does not give the clean angle I want. Somehow it comes out round. I've used a generic coping saw with the assistance of a mini swivel vice, but I have to make the hole large enough to pass one end of saw blade through.

J

Try a jeweler's saw--a much more precise tool than a coping saw although they look a lot a like. These saws are fairly inexpensive (student grade) and you can order blades you almost need a magnifying glass to see. You can get much crisper holes than a coping saw. Google jewelery supply companies for sources.

Malo 'aupito,

JohnnyP for that tip, I'll have to get me one of those.

pdrake for that tip on staining the bone in vinegar & tea on basement kahuna's thread.
I just made a matau & stained it. It will be posted on my own thread.

Any tips on how to make shell inlays, especially the perfectly round shaped ones. What tools are used to create such small inlays?

For sharp cut-outs, I use an inverted cone bur and/or a small set of jeweler's files (both regular and diamond).

A good tip I got for inlays was to super glue a small piece to a stick so you can rotate it as you grind away the outer diameter. I guess you could also use a dowel rod of the diameter you wanted to use it as a guide as you shaped the inlay. You can also buy inlay in standard diameters already round... but where's the fun in that?

Thanks tikimango,

Those tips help. I've been checkin the net & found a site for those already rounded but as I looked at the pics, you're really limited with what they cut for you which are not really quality selections.

I did however find shell laminates & veneers that they were selling also. Has anyone ever tried using these and if so how'd it work out to your liking? Are they made from real shell or faux?

Here's the site, http://www.mopsupplies.com/paua_shell.html

I bought a sheet of veneers and tried to use them when I started playing with the idea, but didn't like them. Very thin, and inconsistent as far as color. Your best bet is to get your hands on some real shells or buy a bag of "chip" shells. Is feels wrong to cut-up a whole shell because they are so great to look at, but its the only way to get really usable pieces for inlay work. Just make sure you always use a cartridge-style respirator when working the real shell.

Aloha Bone Carving Enthusiasts,

Someone here PM'd me about how I do my lashing for my fish hooks. I noticed on youtube a couple of guys that drill the hooks at the very tip which I think makes it vulnerable to breaking. Since I couldn't find any more decent sources on the matter, I took the liberty of drawing up a diagram yesterday which I hope is self explanatory. If there are any questions feel free to reply to this post & I can address them for all to read. Here's the link in PDF format.

https://acrobat.com/?i=1aGL7aih3WewHP01PyOgkg

Steps start from top L-R.

A few things to point out, in the first step, I run my loops at least 3x around main cord for strength. It can get difficult but with patience & practice it will eventually work out.

Before starting the 2nd, I make sure my loops from the 1st are pretty secure & that the pendant tip(make sure it's has a sharp point) is right under the main cord, practically touching it if you will. All your bindings from here on out should be fairly tight. I usually will wrap this around more than shown. I wrap till the tip is secured & I know that it will not come out through the sides. I usually will stop till about 1-2mm of the tip is wrapped.

Step 3, just running figure 8s around in an orderly fashion being careful not to overlap each other. The only ones that I do overlap my figure 8 lashings on are the loops that attaches the pendant to the main cord from step 1. That is to hide it from sight.

Step 4, when done, I hold working end in place thru loop while I use a needle nose plier to pull the starting/cut end above the main cord. I pinch the tip of string, wrap it around the needle nose by rolling the plier till it reaches the lashings & pull till the loop on the bottom pulls the running end under all the lashing. DO NOT pull too much, just enough to have the loop at least halfway under the bindings.

After all is done I cut off the end I just pulled, as close as I can to the lashings. I then use an X-acto or razor blade to carefully cut the opposite end as close as I dare to, against the bone.

Good luck.

here is my own little cheat sheet for lashing. just found it on google little bit here and there. had a hard time finding anything online to show different techniques.....thanks coconuttzo for your PDF. thought i would share what little i found. hope this helps somebody out there in tiki land

also, a website for peopl that like doing knots.....its a good source

WOW,,, Been a LONG time since I saw the GMAN do some carving like this. GMAN, I Miss you!

Duddy,

Perry asked me to put together a few pics and ideas here to get you going. Here's a try at a medium sized bone "how to" lesson with pics of pieces I made previously. I hope this helps. Here you go...

Get a piece of bone from a pet store or a butcher. Most of mine comes from a butcher and I clean it up myself using a wire brush, boiling water, 20 volume peroxide, and elbow grease. Peparing bone could be a whole thread in itself.

So, let's start. Now that you have your bone, think about the shape, side angles, and any flaws on the bone. Now work a piece out on paper, or on the bone as I do. If you made your drawing on paper, transfer it to the bone now. It will look something like this...

Ok, now you need to split the bone with a saw, leaving 1/2 to 1/3 of it left for your carving. I use a machining clamp and a jigsaw for this, but a band saw would be the tool of choice. Do it like this...

Ok, now we are on our way. Next, you need to rough out the shape according to your drawing. I use a scroll saw to do this....

As you can see in the pic above, I have also used a drill press to make small holes in the areas where I need to do open work. Once I rough out the main shape, I use the scroll saw to remove the material inside the open work areas.....

Once you have the bulk of the material removed we can start doing the relief carving. For this I use a Foredom flex shaft unit and a rotating handpiece. If you have a Dremel, this is where you would use it.

First I use a Typhoon bit to work on the back edges where the bone is angled and may be very thick. Watch yourself here, these suckers will really bite ya. This removes lots of materal FAST. I do not recommend using this bur for anything on the front side of the piece!

Now I start using different cutters and remove material giving the piece it's basic front relief/side profile. For areas such as legs and arms where large areas need to be reduced, I use the long cutter pictured below. While using this, I lay it flat and draw it toward me (kinda like using a pen knife). I have wrapped cloth around the tip so it doesn't bite me. I use a smaller "pineapple" cutter to work the edges around the faces, arms etc, where I need to use the tip and be precise.

Now I need to switch projects, as my pics ran out :)

So here we are at a similar stage in another piece....

Once we get most of the relief carving done on him, I give him a quick hit with a rough sanding drum and a medium sanding stone.

Now we are ready to use a bunch of smaller toolz. I generally use several sizes of bud burs, ball burs, diamond burs, and other cutters. Here you should have a mix of styles and sizes because it will be trial and error to find what works best for you. Here is some of what I use.....

a small bud....

a smaller bud....

Diamind burs in several shapes/sizes are good for cleaning up saw cuts and for working in tight areas....

For nice even detail lines, I like to use bud burs and lay them on their side. By doing this the tool with track straight and not leave a funcky, wiggly, uneven trail like a ball bur.

Once you get all the details in and all the cleanup diamond work completed, it's time to sand. I hand sand using 100, 150, and 220. Then I switch to my rotary handpiece and use impregnated plastic and rubber attachments. These are great for getting down into detailed areas and removing sharp edges.

After these, I often sand with 300 on up to 1,000, but very quickly.

Next, I use a polishing buff for a quick hit. You can use some super fine polishing compound/powder if you wanna get it any smoother.

All that is left now is to add some age/color to it if you want to. I like to use a lipton tea bag and some cold water to make a pigmented bath for the bone. The amount of color picked up by the bone depends on the strength of the solution, the degree of polish you put on the bone, and how long you leave it to soak. 12 hours should be sufficient for a real rich color. More highly polished bones will not take color as well. If you have a high polished piece and the tea isn't giving you the color you want, add a little cold coffee. Be sure to check it often as the coffee adds color quick.

After coloring, you can give it another hit with the polishing buff to lighten up the high areas which will age it a little more.

well, there you go. I hope this helps.

Hey guys i'm thinking of starting bone carving got my dremel and stuff :)
but i could only find pig hip bone or Femur. Will it work ?

And how do you prepare your bones for carving and make them so white :)

Hi Skoko. Its been a while since I did any bone carving but can safely say that any dense bone material is suitable for carving, its really only the crumblier porous material that isnt any good. Beef 'shanks' are the preferred bone simply for the fact that you get a decent thickness slab to work with.

Whitening is achieved by boiling with soap or bleach, although I have heard bleach can weaken the bone and is a shunned practice by the true boners. The whitening occurs due to the oils being washed out from the bone. If youre starting with meaty/marrowy bones it can be a smelly job, best done outdoors.. Maybe add a little aftershave to the brew?

Best of luck!

Thank you very much for the answer.Because here (in Bulgaria) very few people eat beef it's next to impossible to find a bone unless you kill the cow yourself :P.On the other hand you can find tons of pig and sheep bone at the butchers.I'll try whit pig bone for now and tell you how it goes :). 10x
