I found a local guy selling a Wilson brale c diamond penetrator and three test blocks in a kit. He wants $200 for them. The blocks still have plenty of space for tests. I'm in the market so what do you think. Is this a decent deal?

I just bought a rams rockford hardness tester for $200 off eBay. Wondering what test blocks I should get. I mostly use w2 and Abe-l. Thanks

I just got some 1075 from Aldo and was wondering if 1500f was were I should start for the austenizing temp. I'm working on a 1/4" chopper. I read that 1500 was good and also read it needs a little higher temp. Just looking for a good starting point.

I tried quenching a couple w2 1/8" profiled knives in water. I didn't grind the bevel yet. I'm just playing around and I usually quench in parks 50 and have been happy but just wanted to experiment. Neither knife hardened. There was a lot of the boiling type activity going on and I used my same...

I have been having issues with breaking off the edge bur. It doesn't want to bend the other way when stropping or through wood. It doesn't bend or break without a lot of pressure. This is with a .oo1" primary edge. Is this good or bad?

I can't find any 1084 or 1075 in the size I need and was wondering how 1095 would do for a 11" blade parang. I'm confident in the heat treat I'm just worried about it being able to take heavy chopping. I haven't done much with 1095 mostly 1085 and w2.

I treated four W2 coupons today. All were normalized 1650 to black 1500 to black 1350 to black and two with a 1he 1200 soak. Two were quenched in parks 50 at 1460 and two at 1470. 1 of the 1460 got a 1200 soak and one of the 1470 got a 1200 soak. The 1470 with a 1200 soak was by far the hardest...

Just wanted to say the eyelet dyes from USAKnifeMaker are as good as it gets. I installed them in my arbor press and got perfect eyelets on the first try. Wish I got them sooner. No more cracked eyelets for me.

Just wondering how you guys factor in non material cost's. Do you have a quick and easy formula for adding the cost of a knife not including labor or materials. I mean belts, electricity, sandpaper.

I have the kbac27d vfd with the on off switch. Is the Orange and green power/status lights supposed to remain on when the switch is in the off position? I also have a 1725 leeson with a 4" pulley and 3" on the grinder. Full speed is pretty slow. My pots are set up the same as Beaumont's...

Looking for a plates chiller for my KMG. My research showed Nathen the machinist makes a nice one but it looks outdated. Any info?

I plan on doing 3-6 folders a month and am looking for opinions on milling machines. First off, would it be worth getting one for 3-6 folders a month. Second; being price and space are a concern, would the bench top models from say harbor freight worth it. I have a little unimat with mill...

I have a Tens machine from a back injury that I never use anymore and was wondering if anyone has used or thinks it may be used for a etcher. For those who don't know, a Tens uses a adjustable electric pulse to help relieve pain to the body.

I've been using AEB-L for the last couple of knives I made and they are magnetic after heat treating. Is this normal or do I need to change something in my process.

I'm having a hard time getting a dark etch on stainless. I made my etcher from plans online (can't remember were I got them). I'm using Ernies stencils and the green stainless solution. I cleaned all my contact areas and have good ground. I get good etching on non stainless. Any ideas.

I have a opportunity to get a great deal on a unimat metal lathe. I can get it for free but will need to buy a chuck and tooling. Do you think it would be worth getting? I only made one folder but will make more in the future. Would this be a useful lathe for folders or would something bigger...

Just wondering what you guys think about using grinding jigs. Would it benefit or hinder your grinding skills? I built one but never really got into it but now I'm making more knives and selling them. I can see how they could help with speeding up production but I'm worried my skill level would...

Just curios what your thoughts on water or oil quenching air hardening steels in the air/water tight pouch. Does stainless benefit from rapid cooling? I'm sure there is a reason not to do it but I do not have the knowledge to know. I know it wouldn't cool oil hardening steels fast enough but not...

I'm stumped. I have been lurking here for some time now and usually find answers that were already asked. I have a evenheat oven and just getting into stainless (440c). I followed the evenheat info for 440c, foil packet at 1900 for 15min. I used 1" aluminum quench plates. I did not let the...
