Acordian fold?

Anybody got a good description or tutorial? I've tried one and it didn't come out too well, got weld shearing in the center of the cut outs. I was attempting firestorm pattern and made some expensive scrap.

Thanks,

Will

Will,
The key to unfolding accordians is slowslowslow. Do it at welding temp. and unfold slowly, reheating often.
Try fluxing your "scrap" piece and rewelding the sheared area. I've saved quite a few billets this way.
Good Luck
Jon

accordian made easy

It is never easy but this will work. Get an old paper back book open it near the middle.
Look at the edge near the spine and you will see two ears sticking up. This same shape forms in the steel as you open the bar. grind these ears off. It really helps open the bar. I have a series op wedges made for my press to open this type of pattern . Work the bar hot. Stop once in a while and thermal cycle the bar to reduce the grain growth cause by the high heat. This grain growth is the cause of most shearing problems,

Anothe method is forging the bar a little thicker than required for the blade . Use a set of heavy ladder pattern dies then grind it flat . You will get almost the same result as the accordian method. With a lot less failure.

This is from by website.....
Accordion Fold?????
Many people have asked me how mosaics are created............well, it's a lot like putting a puzzle together. Building it is the hardest part. Once a desirable pattern is achieved within a bar, the question is....."How do I make it come out on a blade?" Since a picture is worth a thousand words...............here's how. (Remember, when building Mosaics, all of the pattern is located in the end view of the bar, this is how you get all that cool pattern to the "flats" of the billet)

good job Ed

The methosd Ed is using gives the best view of the end grain. There is a lot of waste with this method but it works very well. The waste cut can be rewelded into another very interesting pattern so maby it is not waste. Look at figure #2 if you open that bar with out grinding the edges the bar will form the ears . Ed removes the ears in figure three. To get the most material out of the bar drill the bottom of the cuts then band saw it open . Then carefully push the bar open until it reaches about Eds figure #2 then grind the bar as shown . You will get a beter sucess rate by thermal cycling the bar to reduce the grain size at regular intervals while forging this material. Good luck
Thanks Ed for the great pictures

I do exactly what Ed does, except I first drill a 1/4" hole at each apex, and bandsaw to that drilled hole. This helps me out a little when I'm opening it up. I open at a forging+ heat, and go very slow.

Thanks guys, that's a big help, still trying to learn how to use my new press and making lots of expensive scrap. Never even considered rounding the outer edges, rounded the inner but

Ed I sent an email about your mosiac vidio, should be a big help also,

Thanks guys maybe I can figure it out now.
