Yep! There was a time when they used to go to the scrapyard, but then I got the idea to put them in a can.....fill all the air space with powdered steel, and weld it up.....that's how my "Fossil" Damascus came about.

Ed,

Thanks for the tips on opening up an accordion cut. I like your bottom die for the press. GOOD idea! I have a similar die that I built for a custom project and never thought of using it as you did here.

If you don't mind, let us know how you round over the inside corners of the accordion cut. I have been pre-drilling the billet and sawing to the holes but would be interested in how you do it.

Glad that you're back in the shop.

All my best.

Gary

Hi Gary!

To round out the bottom of the "V" cuts, I use my chopsaw.....I pin the guard back, turn it on and hit the "lock on" button, then gently radius out the bottom of the "V" cuts. On the outside "corners"...I round all those using an 8" contact wheel, and freehand it. The big key is to make sure that the thickness is as equal as possible throughout the cut billet....especially right at the hinge points (the space between the bottom of the "V" cuts, and the direct other side.....guess I'd call that the outside of the "V" cut. The reason is that when you open up those "V" cuts, there's a huge amount of tension on the bottom of the "V"....and a huge amount of compression on the outside....that's always where things will "tear". I did the drilling and saw cut method for a while.....and only had about a 50% success rate.....so I went to the "V" cuts, and the success rate went way up. It's a lot of "waste" for some folks....but I recycled all the cutouts into my "Fossil" Damascus.

Nice tip. Thanks, Ed. I had a lot of trouble with fractures until I started working at welding heat which has eliminated most of the problems. There is soooo much to making Damascus but that's why I like it. If it was easy then where's the fun?

Thumbs up very cool!

Hey Ed!

That is one cool looking pattern. I don't know why but it reminds me of "grapes and bacon" .....must be hungry!

So, when do we get to see the rest? I'm also on the edge of my seat

Finally got one of the billets from the can finished down and etched this morning.

This piece is 12"X1 1/4"X1/4". All total I got 3 billets of that size, and two billets of the same length in 1 1/2" wide. 5 feet of Mosaic damascus, and lots of "pieces" to make "Fossil" with.

Took these pics in the shop because I wanted to get them posted....so they are less then perfect....but it works for what we're doing here.....









Just anothe day at the office!

Wow, that is some amazing damascus.
How long would you say it took to get from starting the can to this point?

That's a cool looking pattern, Ed. What are going to call it..? Kind of reminds me of that south western pattern they called Ojo de Dios or something like that. Snyway, it looks great.
