Hi, all. Just found this Forum and frankly I am boggled by its size and complexity compared to the woodworking Forum where I hang out (WoodCentral.com) . If I get an answer I hope I will be able to find it or email me direct bjtindall@mindspring.com.
To cut to the chase I need two pieces of CPM heat treated bar and I am looking for someone that works 3V to supply these two parts- I need a couple of pieces of 3V eventually heat treated to make a pair of specialty chisels. I can do the required simple grinding on the heat treated bar. There is great economy of scale if someone already has the metal and is sending out many blades for heat treating.
The requirement is about 1/8 x about 1/4 x about 6" minimum, and about 1/8 x about 1/2 x about 6". No hurry at all, been thinking of this project for 2 years.
We have found that CPM 3V which combines high hardness with toughness makes an excellent woodworking chisel(plane blades too). In many cases the chisel is struck to shear the wood fibers cross grain. This operation puts vastly more stress on the edge than simple paring or planing which is largely with the grain. A chisel edge beveled to 25 degrees must be tough to prevent micro chipping at the tip as well as hard to resist deformation(bending). I have lots of photomicrographs studying these dulling processes. 3V hardened at at least Rc60 does very will in this application, much better than the typical woodworking metals A2 and O-1 or even M2 which chips.
I have made chisels and other woodworking tools (plane blades , lathe turning tools, etc) in the past for my use but that was long ago and I don't have any metal left. It is impractical to gear up for two small parts.
Thank you all for reading......
