A typical hammer is going to be somewhere in the low 40hrc range. Not hard enough to dent a hardened knife steel, which is usually in the 65-70hrc range. Hence the need for the tungsten carbide ball bearing, which is going to be 70+hrc. For those wondering why you cant just use a regular hammer. 🙂

Why not buying a carbide pin, glue it inside the hammer and grind it round at the tip? You can get round carbide for cheap.(broken Endmill) I measured some of my hammers. The are around 60 HRC

I partially dissagree with you. I made an apprenticeship as a tool and die maker in the late 1970‘s. Straightening thin mold parts that got warped after heat treatment was standard practice. We all had our shop made ball peen hammers. Either with the ball end turned on a lathe or a steel balls insterted into a hammer head. Also a steel ball will „deform“ a hardened blade to be straigthended. I still have my hammers from that time. I just straightended a blade hardened to 62 Hrc with a ship bought hammer you used to inlay the ball. But the ball end is flattened. That said, I also made myself a hammer with a realtively sharp carbide tip to straighten blades. And for sure a carbide ball will not deform. So instead of a carbide ball a steel bearing ball can be used. The dimples will not be as deep/pronounced though

Maybe the base steel (but highly doubt it’s even that low, probably around 45hrc), but the face should be case hardened to around 50hrc to mid 50hrc. If you measured this then it’s possible the surface had a lacquer or coating on it. 40hrc is very soft and would probably be damaged by a typical framing nail when trying to drive it in. Just a little fyi.

I stick a speaker magnet to the drill press to hold the chuck key and some other tools. Seems to be the only way to avoid misplacing it all the time for me.

you can make this by simply rounding off the hammering end of a hammer btw, or just buy a good ball pin hammer, he just went x10 on it!

Congratulations! You’ve just completed your very first bezel setting! Usually done with gold and a gemstone, but the concept is almost the exact same. As you found out, the key is to make the hole almost the exact same diameter so it’s a very snug fit. As long as the the center of the ball is just slightly lower than the level of the hammer face, it’s all a matter of reducing the top of the hole diameter so it’s smaller than the diameter of the ball. A word of advice… after a while, the ball will sink deeper into the hole you made in the hammer. When this happens, just squish the edge you hammered down tight again. It will eventually reach a sort of equilibrium where the ball will require more force to compress hammer steel than you’re applying to it. Now that you know how to bezel set, you can apply this technique to your knife making, such as metal inlay. Have fun!

GREAT INFORMATION. I was wondering if he set the ball in deep enough. But as you explain it will achieve its equilibrium. I was also wondering it the JB weld was necessary? So to recap,for my understanding the hole size and depth are most critical in order to make a long lived tool.

@nottheoneyourelookingfor0504

@@Curtislow2 hole size is crucial. Too narrow? It won’t fit, or you could accidentally break the ball/gem by trying to force it in. Some rare cases you can hammer it in if the thing (the ball) is significantly harder and not brittle. Too wide, and you won’t be able to push the metal over it to keep it in. Well, you technically could, but you’d end up deforming the hammer so much after so much work that it’s not worth trying. Hole depth is just as important, but there are things you can do to mitigate any errors. Too shallow, just drill deeper. A little too deep? Drop a spacer inside. Think like shimming. In my experience, glue isn’t necessary. It help keep the ball from falling out while pushing the metal over it (which wasn’t the case in the video because he had a good fit. With a really good fit, friction will hold it in line in the video.) Sometimes glue is used to keep a stone from moving around within the bezel, but this is for when you don’t have a good tight fit or properly push metal over it. For weaker gemstones, glue can be used as a cushion to reduce the chance of it breaking if you were to accidentally hit it.

Damn! You beat me to it!

I used to work in a saw blade factory, and making the blades flat was done almost exactly the same way. The difference was we had a specialized hammer for the task, and we would shine a light at a polished anvil and use a straight edge using the refraction from the anvil to find our dishing, bowing or warping. This system worked really well, and the top paid guy’s in the factory were hammer smith’s, as knowing when to stop hammering was just as important as knowing where to hammer.

Ahh, the skill of the hammer. Too many people look at hammers as crude. The hammer is the first tool we made, humans have a LOT of history improving hammering. Scythes were sharpened to a razers edge with a hammer. An interesting actual job title from the past is a "Scissors putter-togetherer". Just the right hammer blows induce the curve that makes scissors work. Took years of practice to perfect. Sounds like what a 5 year old would come up with for a name though. Don't get me started on "doing it by eye" meaning you half-assed it to just close-enough. The eye is the finest instrument known to man, we have just forgotten how to use it.

@@ForbiddenCloudGaming I’ll take that as a compliment, though 42 isn’t part of the “older generation”. It may surprise you that hammer smith’s still work today, no machine can do that job, and the blades for the big saw mills need to be flat, really flat, because they will explode if they aren’t, they are a crucial part of the lumber industry. It’s really amazing just how much is still done “the old way”, even though we all think technology has moved past skill, it’s hasn’t. We used lasers to cut the blade shape out of sheet steel, but if the blade needed to be thinner than .050 inches it was cut into rounds because a laser can’t accurately cut that thin and not melt the end of the tooth, a machinist would tooth it, using a machine that is probably over 75 years old, those blades are how you get perforated toilet paper.

Drill press chuck keys - either attach a magnet to the press body or the key and then stick one to the other. I've done both, glue a magnet on a handy place on the drill and just put the key on it when not in use, or drill the back of the key and stick a magnet in it, then you can just leave it anywhere on the drill.

Thanks, I would have hammered on the wrong side and hit it way to hard.

Just a thought expanding on the idea. Use tungsten carbide rod 1. It's much cheaper and widely available in a multitude of sizes 2. It would be far simpler to seat in a striking tool for example a brass hammer that makes use of a set screw to allow for changing out broken bits and 3. You can grind a plethora of profiles other than a ball to allow for more controlled stretching, giving you more exact results and far fewer blemishes that require finishing work. 4. One easy to fab brass hammer with say 5 bit profiles cross peen, ball, chevron, scallop , and perhaps a waffle for some knock off knurlling texture. 6. This would also make the idea much easier to transfer to a small jewelers hammer peice which would increase you precision and efficiency to the point you'd likely be able to work through entire boxes of warped blades in a sitting.

Not everyone has the capability of grinding tungsten carbide. Ideally, you would want diamond or CBN grinding wheels to accomplish it, I think.

Thank you..for such a great tip..

i've been watching people make blades and fix warps for like 10 years now and only very very recently did i see someone use one of these...interesting stuff

I've got a few large carbide-tipped teeth from an asphalt road mill that might work well for this. They usually get thrown away and replaced when they wear down to a certain point. I had never thought much about how hardened steel was flattened before, thanks!

I would use it during smiting too. This is a brilliant design. If you hammer it while it's hot, the microstructure will be more dense, therefore the knives would be far better quality (tougher,...)

Setting that bearing is actually exactly how cabochon gemstones are set in bezels. Interesting to see how much crossover there is in all these skillsets.

Tip for you, you never want to chuck the drill on the flutes. The shank is a softer for a reason, it gives slightly to let the chuck jaws "bite" and not slip. The flutes can damage your chuck jaws, and not allow it to hold concentricity because two flutes and three jaws don't line up. I prefer to buy stub or screw length drills as needed, they're more rigid that jobber length drills, and don't take up as much workspace between the table and the chuck.

Trick to prevent your chuck key from running off and hiding every time you need it: just drill a little hole in the handle, and secure it to the drill press with a length of ball chain. (the type that's used to secure the drain plug to your sink)

I’ve had a lot of success with mine but I have cracked a few blades by using it. I would highly recommend doing both temper cycles before using it and if you’re going over 65 hrc to be careful.
