this method is often referred too as an Interrupted Quench, to reduce stress in the metal from thermal shock.

Some are, but many are not. THIS is the point we are making about salvage.

sadly many so called reputable sources are still wrong, many seem to sadly re quote what they heard, not researching for themselves. History channel is a good example, with a few reports with blatantly wrong information. Just for fun, sometime try to poke a 1550F blade into any hunk of meat and see what happens. FYI for those that wont try this, it may not get through with out becoming a twisted blob, as most any meat is much tougher than the hot metal, and bone...

You could use it for a while, but the metal dust from its use will eventually kill the motor, but its only $3so how long does it need to last to be worth the effort is your call, I would go for it. if a guess is 4000, then most likely in US at 60Hz 3450RPM at 50 Hz 2850Hz

IMHO Seriously if that is the case, get another accountant, if they cant be trusted, as ANY employee, fire them

Knee mail sent

good Idea, I will see what I can do after the change over is worked out

At least I can say you have a better reason for not reading it that most have in the past. LOL the term sticky is used simply because the article was tagged to make it "stick" to the top of the listings, for easy locating. Since you are a long distance away from the oven you should come up with other methods, the simplest is a stress relieving temper by conduction, meaning after you harden; allow that to cool while you heat up another section of metal, rest the back of the spine of the blade against it and allow the oxide colors to run up the edge till you get desired color (nearing light straw) near the cutting edge. then cool this off before it goes "too far" with a fast quench to stop the colors from running further. This should prevent stress cracking before you get to the oven for your temper cycle. also most advocate more than one temper cycle anyway. No reason to Apologize for just starting, we all were beginners at some point, asking is how we learn.

At risk of getting flamed, You should ask your accountant not a bunch of faceless people on the internet about tax/business issues. I ran my own Electrical Company 16 years before I sold it and joined the Union to work for someone else. I tracked everything in a simple database and the accountant knew what was allowed and what I had to pay taxes on. so if I got consumables for myself under the number I was still covered legally. I had all that licenses/tax/Insurance stuff and it was not that much of a pain, but the risk of going to jail for tax fraud, or losing my house for no insurance to cover an accident is a pain, my forge has its own tax number and is insured. Remember Al Capone, Chicago mob boss... they finally got him ONLY on tax evasion.

My portable forge has a 22 x 28inch sheet metal surround to the cast fire pot,( its 10x12 drop in), 12 ga I think, easy enough to work with tin snips. and after 20+ years I have finally seen a need to repair it :)

Welcome Jesus, Glad to see you finally made it here. Make yourself at home.

welcome to the site, and I already wrote out your answer in the Sticky's here in the knife heat treat section Dont forget to post photos of your finished blade, we all love pic's

My mother that never gets, at least not admit to being sick anyway, and she refuses to even get a check up at a doctors; has been sick for a month and seen the Dr 3x in the past week, plus another apt is set for Wednesday. She can not see in her left eye now, nor have much control of her left side in general. The major doses of antibiotics have had no effect other than the G.I. effects expected with such levels. She is in her late 70's so Dad is scared she is going, whether that is a fact remains to be seen. Xmas gathering this year has been canceled/postponed.

Ya know, after sorta knowing Jim all these years I fear to ask what he will quench this in, as in the past he has followed livestock around to collect "quenching liquids..". and for a buffing compound :o

my last one I riveted, I used Wrought Iron rivets I made from the bar I had folded to make the guard from... No press here, yet

By NOT tempering you have retained brittleness in the steel that can result in failure. Re-read about what tempering does to hardened steel to see its also relaxing the steel from the thermal shock of the hardening process.

Critical Temp also depends on the alloy we are using at the time, they are not all at the same temp for proper hardening.

If it really is nickel silver and steel rather than normal 201 pure nickel with steel, Then I would be careful of heat, or to even attempt a heat treat as the copper alloy may melt out of it.

actually I did, its at my web site, here is the direct link Making a Damascus Katana and thank you for the kind words.

technically, copper IS like most other metals. steel is a minority about quenching to get hard, Just a FYI also you didn't state if solid state fusion welding or soldering to join the laminates, that does make a difference in how hot, or cold, it should be worked. Or what metals you have tried.

Also I might add that most the time those of us that "break the rules" to expand frontiers, almost always start with a grasp of the standard procedures, before the experimentation. Like the popular comment about designing a race car, without first learning how to drive...

you posted about a knife and it was moved there with other knife topics and it is still labeled as relocated, the link is still here...

The results have been confirmed, Sean has an enlarged liver, mainly due to fatty deposits, combined with lactose intolerance explains his problems since last spring. He has a new diet and is back in school, NO hepatitis thank God

My 14 year old son has been having medical problems since last fall. This last round has had him home for over 2 weeks now, starting with severe lower abdominal pain, ending only when he passed out from the pain after 40 minutes of screaming. I have and will contuinue to be involved with I Forge Iron, but lately my son has keept me too busy to be here very often. and now we are told the main trouble is his liver. I love you all and have not forgotten this place, but have not a lot of free time for chat rooms lately. so other than minimal staff work here, I have not been around and thought you all deserved to know why, Nothing personal.
