Alternate ivory disaster

[Rifleman1776]

I am.....correction...WAS....in the middle of making my most expensive pen yet. It, maybe someday, will be an Emperor. Kit is $55.00. The material I was using is a form of alternate ivory that, at one time, I had aspirations of selling. Long story short, that didn't come about. This material is known as white paper micarta, or a/k/a white paper phenolic micarta. It is widely used for knife handles and pistol grips. It is a very different product than what Craft Supplies, and others, sell for pen blanks.
This stuff is very hard to turn. And, I do mean HARD. For half a blank, I had to sharpen my Henry Taylor HSS skew three times. Plus, it gets very hot, as does the tool. I paused frequently to let it cool. But, perhaps not enough. While nearing the end of turning the second half (I don't use a mandrel and only do one half at a time) it suddenly blasted in half on me. I don't know why, excess heat maybe. Dunno fer sure. :dunno: However, as can be seen in the picture, the interior of the broken half doesn't have much glue on it. I use 5 min. epoxy. Maybe the fit was so close it all got squeegeed out. Again, dunno. :dunno: Maybe thin CA would be better. This piece of alternate ivory cost about $10.00 but I'm grateful my $55.00 kit is still intact. Not sure what I'll put on it now as I was really looking forward to this ivory, it really is a beautiful material and looks far more like genuine ivory than the CS stuff. I have a blank of white bowling ball material I got from the circulating box, may use that. Or may use some alternate jade. Oh, did I mention I am not a happy camper at the moment? Plus, I'm not in a mood to go out and kill another one of those alternate elephants right now.

if it was the upper half that broke, I'd think about doing another material on the bottom half, maybe some ebony. Then you could have your ebony and ivory pen.

Thanks. But, I have made the decision to kill another alternate elephant. Will finish the pen per my original idea. I'll have some expense in it though. The additional cost will be about $15.00. Add that to the first hunk of AE, plus the kit, I'll have more than $85.00 invested.
BTW, an all ebony Emp. could look fine.

Sorry to hear of your problems Frank.

It looks like the pieces are both there. I would take a scrap of the material, create a small pile of sanding dust, Reglue the pieces to the tube and fill any gaps with thin CA and the sanding dust.

From the photo it appears that the tube may not be scuffed? The brass tube must be roughened with sandpaper or plumbers cloth to make sure the glue gets good adhesion. There is a lacquer or coating applied to the tubes to prevent tarnish and it can prevent the glue from adhering. That is why it is easier to remove glue from the inside of the tube than the outside.

Where did you get the material?

You may want to consider a carbide tipped tool. I use such a tool to work with very hard Trustone blanks.

As Ron White says, "If life hands you a lemon, make lemonade, or go find a person who got vodka and have a party!!!!!!!

 

[Russianwolf]

looks to me like it broke right along the grain. nice and straight and flat. Glue it back together and see how it looks, you may not even notice the cracks.

 

[txcwboy]

As a knifemaker also, I would that IS NOT Micarta. Ive never seen it break. Its a laminate. I would bet its closer to Ivory Corian. I justed turned some Alt Ivory I received from one of the blank makers free as a sample and it was very brittle and I had chunking issues. Sorry to hear about the loss.

[desertrat]

White paper micarta is made up with layers of paper much like plywood. Thats why it looks like real ivory as it ages. Sounds and looks like too much pressure caused it to split along one layer of the paper. I've used it for custom knife handles for many years. Key is to go slow and keep it as cool as possible.
Good luck

The first piece of alt ivory I tried to turn blew up on me but on an end. My fault, I tried using a spindle gouge and got a catch. I was able to salvage it by making an ebony and ivory pen. Since then I haven't had any problems using a sharp skew and have now turned quite a bit of it. I got my AI from Ed at exoticblanks.com. He's got good prices and quality stuff.

That is a good tip Randy. I bet Frank knows where a "poor man" can make such a tool.:wink:

 

[ed4copies]

Just to clarify

Thanks for the plug, Dave.

Frank TRIED to make this clear, but the headline doesn't.

The material Frank is using is NOT the alternative ivory that I import.

"This material is known as white paper micarta, or a/k/a white paper phenolic micarta." Which is also referred to as alternate ivory.

Two different materials, VERY SIMILAR names.

 

[alamocdc]

That's too bad, Frank. As has been said, I'd scuff the tube and glue it back together. If it doesn't look good, then I'd use a new piece. Should be pretty stuff when finished, though.

Frank, If it were me doing it over again I would focus on the red text above as I think they contributed heavily to the cause.

I turned a truestone blank once and wasn't paying attention to the heat it generated and actually had the blank spin on the tube even though it was glued.

When I started turning I used CA for everything, then after examining a few failures I realized that the CA wasn't the best choice for gluing blanks and that sanding the brass was also important.

When I switched to epoxy I still had a few failures and noticed that in every instance, very little glue was left between the brass and blanks.

I started questioning why kit makers recommended certain size drill bits, and what were they basing their sizes on? In several kits, the bit recommended barely allowed for a tube, let alone any glue. I would wager that a high percentage of failures is due to not enough glue because everyone is following kit recommendations!

With some kits I started using larger bits which allowed a thicker glue line and haven't had a failure since. That is what I would focus on regardless of what material the blank is made of.

Hope your next blank works out better for you.

It is my understanding that "heat" is a killer of ca glue. Since this material gets so hot you might try some other type of glue that might not turn loose as easy. That would eliminate maybe one possible cause.

I agree, the tube 'appears' to not be scuffed. But, I, fer certain, fer sure, did rough it with 40 grit sandpaper. I always do. I'm not inclined to glue it back together, especially not for a high end pen. I have carbide but will use much greater caution with the heat build up on my next go around. But, thanks for the suggestions.

Hi Billy. Yep, I'm going alternate elephant hunting today. BTW, it was scuffed, doesn't show in photo.

Yep, sumptin' else to worry about. ;-)

 

[workinforwood]

Gorrilla glue..that's what you need. If the hole is so tight that most of the glue comes off, it won't matter, because the glue still on will expand and gold nice and tight. Heat is far less a problem with gorilla than it is with CA and epoxy. I'd glue it back together..what do you have to lose..a broken blank? How about having someone drip water on your chisel and blank as you turn it down?

 

[workinforwood]

Oh...I see you said you are not going to glue it back together. Just remember this though Frank...it was glued together before you broke it! :wink:

When this blew out, the first thing I did was to explore much of my seldom used vocabulary. Then I wrote my post, saved it in Notepad and hastily took the picture.
I never did really examine the gory remains until a few minutes ago.
Surprise, the 'unscuffed' tube is really COMPLETELY COVERED WITH EPOXY GLUE. The glue did adhere to the tube. I am now convinced that heat was really the culprit. Next time I turn this stuff, I'll first bandsaw down as much as is safely possible then turn with frequent long-long pauses for cooling.
The way this stuff comes from the dead alternate elephant, there will be enough for two full blanks, and I'll have another 1/2 left over. Dunno if I'll personally use it or maybe sell, trade, give away or burn at full moon while doing a voo-doo dance over it.

I expect you could make a few bucks if you sold tickets to this event!!

 

[elody21]

Rifleman,
I know this is not the same but I could send you a 3/4" piece of Ivory Corian. It makes a very beautiful pen and no seams in this piece! Alice

Thanks, Alice
I gave away about 50 pounds of Corian not too long ago. Not fond of turning the stuff. But, I do appreciate the offer.
A solution may have come along. I'll post later.

I have a difficult time mastering the skew and sometimes shaky hands make it worse. But from what I hear, the skew is the way to go with this, and yet I really need chisels that lay flat on the tool rest.

So, for me - I have taken to sanding down to size when I get to within 3/32 to 1/16 inch on delicate and hard to manage material. It sure takes more time - usually about 10 to 15 minutes for that little bit, but when I value the blank more than my time, it is safer. On the one of a kind, special pens like that - I jump away from the tool quickly and go the safe route of sanding. Of course, I don't do this on most pens.

Others have commented on the "80 Grit gouge" but I've only used it when I had to. That's my story and I'm sticking to it!

 

[TurnaPen]

Definitely make sure you scuff the brass tube, and when putting the 5 min epoxy on, use a cotton bud to line the inside of the blank with it also, this will make sure it gets glued all over. Amos

Hank, the skew does lay flat. But, with this material, it acted more as a scraper than a cutting tool, as with wood.
I do some of the final shaping with sandpaper, but only in the last couple thousandths range. Seems to me that to remove much material a coarse grit would be required. And, some of those would scratch so deeply that they might not be able to be sanded out. I'll just take my time and allow ample cooling at intervals.

In this case, the glue was where it should be. As much as I suspect heat to be the villain, I am going to scratch the inside of the drilled blank before inserting the glued up tube. This should give a better grip. But, I'll still take precautions against excessive heat build up.

Another tool I have started using and like for Alternate Ivory and acrylics is the Sorby or PSI copy of the Spindlemaster.

Just thought I'd throw my 2 cents worth in.

project saved

Well, as luck would have it, last night, after closing the big door on my shop I heard a ruckus. Went to look and came face to trunk with a genuine alternate elephant that got locked in. I think he may have been attracted by the corn I put out in the deer feeder. They aren't very large so I saw an opportunity to finish my pen with some new alternate ivory.
After wrestling him to the ground, I removed one tusk then let him go.
Shown is what I got. Enough to finish my Emperor, make another pen, maybe a Patriot and some that I segmented. The black in between is paper thin ebony. I'll attempt that at another time.
Watch for either my finished Emp. or a report of me going completely bonkers after blowing another blank.

 

[fernhills]

Take two Aspirin, see me in the morning. Carl

 

[Rifleman1776]

finished

Well, I finished it. For a while I thought the project was jinxed. Assembly was pretty straightforward except one part was screwed into a completely unrelated part and when I put it all in it was, of course, not right. I had a pucker moment disassembling without crushing or scratching the part. But it worked. It will be on display for sale in the gift shop soon. My highest priced pen yet. Of course, I hope it sells. But, a big reason I want it there is for marketing purposes. This will be the top end item of my 'catalog', priced at $340.00, a $120.00 pen will look very affordable.

 

[pianomanpj]

Frank,
That is gorgeous!! I'll bet even that alternate ivory elephant would be impressed enough to sell his other tusk to buy that pen!! :biggrin::biggrin:

Very well done!!

 

[DurocShark]

It's beautiful, and worth the trouble.

 

[CharlestonPenWorks]

I had a similar accident with Eugenes ivory blanks. The whole bottom 1/4 inch of the upper pen cracked off while turning. So I took this opportunity to add some Buffalo Horn (jet black) oops rings to the bottom of the top barrel and to the top of the bottom barrel. It actually turned out nice. Sometimes, oops can be a blessing.

I had a similar problem with the only Emporer I have turned.... Whoever is packaging these needs to "RTFI" better!!!:at-wits-end:
