Finally, all of my Christmas gifts are done!:D Now onto bigger and better things.;)

Here is the latest pen. It is the large Gentleman's pen style made out of 37 layer straight laminate copper and nickel silver mokume. It turned out pretty good, only one minor oops, but hopefully Grandpa won't mind. I was kind of supprised at how nice a straiget laminate can look.

Hopefully the contrast will get better with age and use. I just hit it with a little ammonia to get what you see now. I had it baking in ammonia vapor and left it in too long, but some spots had a nice purply color to it. But it wasn't even, so I refinished it.

What's the final thickness of the damascus barrel?

If you're not using a lathe, how are you milling it?

Just curious...

Dan-

Lets see, the final wall thickness on the cap is about: 0.037
The final wall thickness on the lower part is: 0.067 and 0.033 at the taper.

I use my mill as a vertical lathe. Works ok, but can still give me an 0.008 difference on concentricity of the barrels. I use a carbide cutter held in the mill vise, and the table cross travel to vary the diameter.

Hope that helps:confused:
 
Got it.

Run into any other problems other than cracking/splitting, or etching problems?
 
My hats off to you. I liked yours so much I decided to build one this evening. It took me an hour to make the damascus and turn it, and 6 very stressful hours to put the da%n thing together. The carbide cutter is a good tip, wish I'd read it before I evened it out with a scraper and dykum!:o

Are you putting the brass sleeves in or just fitting to the steel barrel?

BTW>..they are all beautiful, I also hope they know what they are getting!
 
Peter-

Common' lets see a picture!:D

Yes, I stil use the brass tube. I tried leaving it out on the mokume twist operated pens I made but that didn't work too well. On the bigger ones, I could probalby leave it out, but by using them and having the hole a little oversized, it allows me to shim the brass tube when I epoxy it into the steel. That way I can get as close to concentric as possible. I am typically about 0.008 off. Hopefully if I ever get a lathe, that should go away, well at least be less.

Hope that helps, now lets see that pen!
