What did you do in your shop today?

Ferric is gonna be best. It needs to be diluted with water. 4 parts water to one part ferric. Lots of folks keep it in a big piece of PVC capped on the bottom. Use pipe dope (or whatever that PVC sealant/adhesive stuff is). You can get a cap for the top too. 

But lemon juice or white vinegar should give you a sneak peek. Doesnt have to be fresh. Just make sure your scale from the quench is cleaned off good.

Good luck!

Okay thanks!  Ive got one more question, Can I use the vinegar before heat treat, just to see what pattern it is? Or will it etch to deep to be sanded off? Sorry for the never ending stream of questions!

You can, but it won't turn out as bold as hardened steel. And don't worry about asking too many questions. It's cheaper to ask questions. 

Etching actually causes a change in topography on the surface of a blade. The acid or salt will corrode the steel with the most carbon, or the lowest resistant alloys more aggressively than the other. So when you knock the oxides off, one is left lower than the other. The deeper the etch; the more contrast you'll get.

Okay! Test etch is done I’m going to sand off the etch, and get ready for heat treat, I didn’t get around to it yesterday. Do you guys have any idea what pattern that is?

Looking Good Conner.    That pattern looks like it started as a small scale crushed W's maybe ?   Maybe with a slight twist in it as well.

Best I can tell anyway's, could be wrong...

600 grit on the bevels 400 on flats, that’s probably over kill for a blade that hasn’t been heat treated yet. But hey! It’s practice.

Finally found the time to build a bench for the coote. Runs great! I opted for the step pulleys on this one. Going to be perfect for what I intend to use it for.

We made some hearth steel a couple of weekends ago. Ran into some issues at first but Emiliano came to the rescue with sage advice. Here is a knife from the material after heat treatment.

Once I sanded it to 600 I re etched for 10 minutes or so, and it got a much darker etch.

I ground half my thumbnail off right through the nail bed. I mean, I did some other stuff before that too, but that's the one that sticks in my mind...

You are correct, on both counts, but the 25# LG does wonders.

I have several used JH bits. They actually sell them at the tool rental in Home Depot, but these were donated by a contractor friend.

I always say that the price goes up if it drew blood during the making. That means it has a spirit and knows what its purpose in life really is.

BTW-That's a smoking Dirk blade

That little axe drift was lonely. So, I made him some friends. Other than a little wire wheel cleanup, these are all as-forged.
