Zeb Camper 717 Posted April 13, 2019 @Conner Michaux 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!

Conner Michaux 194 Posted April 13, 2019 (edited) 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! Edited April 13, 2019 by Conner Michaux Share this post Link to post Share on other sites

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. Share this post Link to post Share on other sites

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?

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...

Conner Michaux 194 Posted April 13, 2019 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. 1 Share this post Link to post Share on other sites
Cody Killgore 40 Posted April 13, 2019 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. Share this post Link to post Share on other sites
nprovos 134 Posted April 13, 2019 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. 7 Share this post Link to post Share on other sites
Conner Michaux 194 Posted April 14, 2019 Once I sanded it to 600 I re etched for 10 minutes or so, and it got a much darker etch. Share this post Link to post Share on other sites

Bet hammerin it out was a chore though............. 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. 1 Share this post Link to post Share on other sites

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.

Gerhard Gerber 265 Posted April 25, 2019 I have a new least favourite activity: pop riveting At least I've started with the aluminium cladding on my DIY canopy, DIY rubberizing of the load bed this weekend and maybe....hopefully mounting the canopy. More importantly, maximum 10 days before I can resume knife making.....even looking forward to hand sanding! Share this post Link to post Share on other sites
Troels Saabye 36 Posted April 25, 2019 I demolished 2 walls in a barn(build in the 1940--50's), and removed some iron railing to make room for a new shop at the farm ,hopefully I can sell some forged nails, charcoal and firewood there - during the removal I found what I believe to be Wrought iron in the concrete, but spark testing will hopefully reveal what it is. But that's a project for tomorrow, now I need some rest - smashing concrete with a sledge hammer is hard work.. Share this post Link to post Share on other sites
