    Attach Contact Wheel

    I have an Oregon Blade Maker, Bader Style grinder and just bought a 4" rubber coated contact wheel with a 1.18" (30mm) inside bearing bore. I'm in a bit of conundrum as to how to attach it to my tooling arm, which has 1/2" and 5/8" threaded holes. I thought a 30mm diameter shoulder bolt that...

    Thanks! I think I will need to invest in some Parks 50.

    Accidental Hamon Line?

    I used a thermometer, but i’ll double check it for accuracy. Do you see any problem with the overall durability of the knives? Actually, I kind of like the lines as they add some character to the knives. Thanks for your input.

    Accidental Hamon Line?

    Thickness is 5/32" at the spine. You'll notice the line starts at the thick part of the ricasso and ends at the beginning of the false edge where it's definitely thinner. I heat treated each blade separately, with a few hours in-between, while the electric fryer was set at a constant 120...

    Accidental Hamon Line?

    I’m working on a series of five knives from the same pattern, and applying the same heat treat with each knife. The blades are 1095, and were brought up to 1475 degrees in the kiln and quenched horizontally in an electric turkey fryer and peanut oil that had been preheated to 120 degrees.The...

    Blade Geometry Question

    Wow! Just what I NEEDED from both of you guys. Never had it explained so well! Thanks so much. You've added a significant factor to shallow, but ever growing knowledge base.

    Blade Geometry Question

    I have to admit, I am confused on how to calculate primary and secondary bevel angles. Using angle blocks or angle gauge, I have in the past determine the primary grind angle at say, 4 degrees. Other sources describe the angle as much larger. For example, one article describes the idea of...

    To Etch of Not to Etch, That is the Question

    Yes, I think you both confirm my fears, Bossdog and Ed. I think I will just leave well enough alone. It's just not in my nature, but I am learning when to hold back and not become a total idiot! Thanks so much for the tips.

    To Etch of Not to Etch, That is the Question

    Good morning, I etched a few of my knives with some new stencils today, and have a few questions that hopefully someone can help answer. The first knife I etched (with my Electro-Chem Etch, Personalizer Plus etching machine) was a 1095 steel, and it etched a little too deep. The second knife...

    Need Help on Bowie Knife Blade

    What about the one that just got back from heat treat that is pictured with the dry fit handle? The lines are straight and even. Hand sand finish? Thanks!

    Need Help on Bowie Knife Blade

    I am hoping some of you "veteran" knife makers can give a beginner a helping hand on this knife. Its a gift for a nephew who asked for a big Bowie, and I am in the final stage of its grinding and assembly. I just got the blade back from heat treat, and I need to decide how to finish the blade...

    Pin Before or After Heat Treat?

    I like that idea of putting release on the inside of the ferrule. Thanks.

    Pin Before or After Heat Treat?

    OK, thanks Fred. I assume drill the pin hole after final fitting and epoxy has set?

    Pin Before or After Heat Treat?

    Oh, I see! Thanks. One more question, when should I epoxy the ferrule to the stag? My original idea was to epoxy the ferrule externally around the lip of the stag where it fits on the shoulder, and internally as the tang is inserted. That way, the epoxy will fill up any gaps internally between...

    Pin Before or After Heat Treat?

    Not sure I am following part of your procedure, Leeco. I get the 1 size smaller idea, which seems like a good way to maintain a tight pin hole diameter for the pin, which happens to be 1/8". What do you mean by a release agent? Is that something that attaches to the tang or inside of the stag...

    Pin Before or After Heat Treat?

    Well, you know you're in a fix when it's 2:00 AM and you still can't decide th best course of action on your latest knife build. My concern has to do with whether I should pin my deer antler crown to the knife tang before or after I heat tray the blade, which is A2 tool steel. The consensus of...

    Clip Point Bevel

    Hi folks. I may be in over my head in a project that started out as a request for a large Bowie knife from my nephew. I'm working with 1/4" A2 steel and am trying to decide the best way to grind the false edge on the clip point end of the blade. I am not confident free handing the bevel, and...

    Heat Treating A2 Steel

    I just figured out how to re-program my kiln controller to increase the maximum temperature to the required 1750, so I'm good to go now. Thanks for your input!
