Good job on the drawknife you made.Your handles turned out great as well.Once i get my wood lathe up and running I will be asking questions of you.Brad but any chance would you know the Rockwell hardness of those planer blades when they are new?

The handles are tricky for me, because I don't have a chuck for my lathe, so I can't just turn a tenon and then hold the piece by said tenon and turn the rest. I have to turn it all as if I'm doing a spindle, cutting it to shape as much as possible while between centers, and carefully turn the round end off with a skew; at that point I'll chuck the tenon in the drill press and do the final sanding and finishing there. It works but it isn't as accurate (and certainly not as easy) as I'd like. If only this lathe had a standard 1" spindle, I could get even a cheapie chuck for it. But I'm stuck for now.
As for the hardness of the steel I used, I've no idea. I could go look on others I have to see if there are any numbers I can run, but the reason I have most of them in the first place is that they've been ground back so far they can't be used in the planer at work anymore, so there's a good chance any pertinent info has been ground away. I have some knives made by Progressive (I think that's the name), and the ones we use at the mill right now are made by Ortho Jones or something like that.
Here's a portion of my knife steel selection:
Those big chipper blades are NOT going to be chopped up for smaller projects! The largest one there is probably 28" long or so and has never been ground or used; just had babbitt poured in once. It would make a really nice shear knife or something. Other than that, the long planer knives are grooved on top to fit grooved holders; there are a couple serrated planer knives, two zigzag double-sided knives at top right, a host of worn-out planer knives, and some 1/8" bandsaw steel strips. I have probably twice that many more chipper knives, many broken, and a few more packs of planer knives too. I figure I'm set for a while. There are Simonds, Progressive, and International knives there, and possibly more.
