Both billets were made, using two strips of damascus, along with an 18" section of H.D. primary chain sandwiched in the center.
The damascus strips were made with [1095/15n20/5160] They measured 3/4" wide--18" long, with 88 layers.

One billet was pressed while still in the sandwich configuration.

The other was given a slight twist, then pressed.

I can't wait to grind the bevels to see what comes on the diagonal.

Thanks Bob for coming over and helping with the twist.

I will be happy to answer any questions, Fred

Done good you OLE DOG.:thumbup: :thumbup: You can see the chain on the first blade on the edge.:cool: :D

Thanks Bro!

The drawn out ovals, is where you see the chain in the twist.

That will be an all chain edge on the pressed billet. Should take a nice edge.

I'm getting inspired! Thanks Fred. Of course, it was performed by a good ole boy from Ohio (Round on the ends and high in the middle OOOOOOOOO HI OOOOOO). I'm from NE Ohio originally, but spent a lot of my first 35 years of life in SE Ohio skiing, swimming, chasing women, hunting and fishing. Not necessarily in that order though. You're doing us "Buckeyes" proud Fred!
 
Just a question for Mr. Rowe and IG - - have either of you ever had problems with slag inclusions or pinholes/porosity in the completed billet because of gaps in the link and pins (grease, dirt, or even forging flux stuck in a crevice)? I don't mean to hijack Mr. Rowe's thread but I was just curious about whether or not using something other than a bar or rod for forging would cause any quality issues.

Other than that, those billets look great and I'm looking forward to seeing the finished blanks.

I don't know how the Ole Fart:rolleyes: did his, but this is how I do mine.
The primary chain is usually clean, just loaded with oil. I cut the chain to fit into the canister and fill the canister with 4600/1084 powder. Heat it up in the forge at welding temp for a 30 to 60 minutes (this depends on the size of the can). Once it gets to the same color of the inside of the forge or you see sparks flying out, I press it in my squaring dies on my press and continue to make it into a smaller square . I always keep it at welding temp thru the whole process.:D

This was my first attempt at this technique. That said; after welding a handle onto the 18 inch billet I brought it up to temp, adding flux as I heated the billet. The chain in the billet was wider than the damascus that sandwiched it. I started by compressing the chain to the same width as the damascus, pressing from both sides so as to get the chain inside the damascus edges. Once it was squared up, I got down to the serious forge/welding. This proved to be the rite approach; compressing the chain and welding that together before trying to weld the damascus that was on the outside.
IG, uses the powdered steel to fill the gaps, whereas I compressed the chain in on itself to fill. There was some dimpling on the outside of the billet after the twist was done and the press had done its work. But it was at no greater depth than in standard damascus.

Thanks for the response. I've never seen or heard of using chain before so I had to ask. Looks great, I'll be looking for completed pics in the gallery.
