:rolleyes: OK, Someone has to be brave enough to ask. What is the Bill Burke mod?

So, from the little work I've done with Ti, I'm under the impression that when it bends, it stays bent. (liner lock?) Stainless at least has the spring to return to true (when properly heat treated). 154CM is more rust resistant than 440C and CPM154 is twice as tough for the same hardness...

So on the idea that different experiences might lead to different expectation, I have 2, wide mouth (a 3" and a 4+") dewars - both old - one is 20L the other is 37L. The 20L tanks gives me 4 - 5 weeks with daily use - and the 37L gives me about 6+ weeks - again daily use. I don't use any...

About all those 9" sanding discs you bought.... Isn't the Beaumont disc 8 7/8? By the way, I have one and the quality is excellent. I also had a 1 degree disc. What Frank said. It may be useful for cleaning up blades, but there isn't a flat spot anywhere on it. Rob!

Neck opening has to be enough to accommodate your widest blades. I have several 20L tanks here that have 1 7/8" neck opening, so that 2" kitchen knife won't fit in. Also, it is very hard on a tank to frequently go from cold to dry/warm. Tanks last longer if they are kept charged with LN, so...

It would be nice if a lawyer could jump in here with some input. I'm pretty sure that - corporation or not - you can be held personally liable if negligence can be proven. Of course, that negligence doesn't have to be reasonable. It just has to appeal to the sympathies of the judge. "So...

You did post it - still showing just a few threads down at this moment. In answer to your question, I started as a sole proprietor - to be honest mainly because I really had nothing to lose. Hard work, good decisions, awesome loyal customers and an awesome, capable wife turned that around...

Enco's benchtop model is usually about $900 - and they have a 20% off sale today.

Well, that takes out the possibility of a blade just too thick to harden completely. It does raise the question of bubble jacket. Even with agitated quench tank, I often see pieces that are harder toward the tip end than the butt end. The answer to that is aggressive entry into the quench...

Groucho. If in doubt, at least do a flash temper - maybe at 325. This will take some of the stress out and give you some time to make other decisions. It will not give you what you want for a well performing blade, but it mights prevent cracks and delamination. How thick is your blade by the...

Kevin Cashen just posted something of a tribute to his wife - and her involvement in his world of knives. Check it out at http://knifedogs.com/showthread.php?41777-Annealing-damascus-to-be-machined - post #5 I owe a great deal of both knowledge and wisdom to Kevin and I'm not going to let this...

Now that sounds like more fun than the BLADE show. :35:

I would suggest that virtually all belts will have some degree of 'thump' at the splice. Cheaper belts are probably worse. I have seen some makers reduce this with cork on the platen but this reduces the ability for a crisp grind. As for the pins, they are quite malleable. Clamping in a vice...

Rather than a dowel or metal, try a hockey puck cut in half - pie like more or less with 1" strips of paper. Only sand one direction. You may want to modify the working surface of the puck a bit. I would not start this at 150 - too much risk of rounding nice clean edges - maybe start at 400 -...

Awesome question. I went through this a few years back. Crucible's high temperatures leave a bunch of ugly oxides and take a look at the curve. A very minor overshoot or variance can make a huge rockwell difference. A number of well respected makers use the low temps - Jerry Hossum comes to...

I'd be inclined to fill it - much as you described, but maybe cyanoacrylate instead of epoxy. Big epoxy patches tend to be gummy and finish poorly. ..... or maybe I just never figured out how. :-)

I know for sure that there is a big difference with martensitic stainless. No idea if it would apply to something as simple as 1095 - but the results would surely be questioned unless hardness and finish approximated that of a finished blade.

There is a process reason to use LN as well. If I buy dry ice, seems like nomatter what I do, It is gone in 24 - 48 hours. If I fill my liquid Nitrogen Dewar, I'm good for 6 weeks of more. Of course, this wouldn't matter to those who only do a few here and there.

Somebody has to say this. Come over to the stainless side. :biggrin: I get the carbon thing for that customer that will treat his knife like his rifle - and a bit of nostalgia to boot maybe with a forged blade. The difference in steel price for a blade is - what - $10 on a knife that is...

Everything Ed said x2. Just out of curiosity, how much warped. I don't think I've ever seen a blade come out "dead flat". (Haven't seen many go in that way either). Straightening or grinding out warp is part of the knifemaking life - way more so with oil quench stuff. Thermal cycling does...
