  1. I am lousy with names and terms, I am bad about using less than correct terminology. so I will be careful here.

    After normalizing I check to make sure the blade is straight, some times it curves, or even cork screws if it was not hammered evenly. Especially when twisted cores in my pattern welded blades.

    when all is normalized, and I am sure it straight I will then anneal, ( it IS a second normalizing in the sense of relaxing the stress that may have gotten missed the first time, some do this 3x, I don't feel its worth it for three times)

    yes the grains grows a little bit, but that will not be a problem, as another normalizing cycle comes after grinding, and before the hardening. Annealing mainly makes the steel easier to work.

    so Yes annealing IS going to relax the steel Just as normalizing.

  2. ok Normalizing is to relieve stress. Annealing does that PLUS softens the steel a lot more. to allow easier shaping cold, ir grinding, filing, sanding,, I better pay more attention to the words I chose.

    Sorry for any confusion my pea brain caused..

  3. annealing is done after forging to relieve stress. when heated to forging temps it erases most of anything that was done before.

    Old spikes may have stress fractures in there already, New won't have them.

    sharp angles, areas of drastic transition of thickness, are stress risers in themselves. so dont use a 90 degree inside corner, rather a small rounding at the intersection to avoid this problem.

    hammering too cold. Most steels have a temperature range they are happy to be forged in, and a range that they are very "annoyed" in IF hammered at black heat it can crack from that..

    Please don't give up, keep trying. Used materials have their own problems that cant be avoided. only worked around

  4. I have found its very hard to get a hollow grind by hand. Most of us use a contact wheel.

    This blade shape and file detail, looks a lot like some kit blanks I have seen, Just wondered, since you posted this as a first blade.

  5. something happened.

    IF you want more detailed answers, we need more detail of the blade, steel type, new/used?, HT, annealed?> forge/stock removal? thickness...

    it could be many things, but with out knowing, its all wild guesses. forged?

  6. Yes, BUt you may have misunderstood the meaning of that term.

    De-rating a circuit is done many times. But de-rating is for the total load of a panel, NOT the individual line, a breaker (fuse, etc) is there to protect the wiring from over load. An example is a 8 unit building, each unit may have a 100 amp panel, but the building set up may allow you to de-rate that to a 400 amp main panel to service the entire building, as when the units are offices, they may have 100 amp sub panels. but never need that much. it does NOT mean to use smaller wires. a 100 amp panel needs 100 amp wire, a 400 amp needs 400 amp wire. 50 amp welder plug needs a 50 amp wire and breaker, IF you have 10 gauge then its 30 amp. putting a 50 amp breaker on a 30 amp line, is removing the stated protection, and can cause you or your kid, friends, etc, to DIE.

    A laundry have have 20 circuits for 30 amp dryers. While each circuit is still a 30 amp breaker, the main panel can does not need to have 600 amps. due to de-rating it can be less than a 600 amp panel, because it should never need that much. But each 30 amp line, must still be protected by a 30 amp breaker if they are wired with 10 gauge THHN wire. Just as 50 amp breakers should have at least 8 gauge THHN wiring.

    Any more info and I will have to charge you :)

  7. I have been using Boric acid as an additive ( about 5 to 10%) to my borax and it seems to work better as a flux, Cheapest way for me is buying a can of Roach Proof ( 98% boric acid) also as Thomas stated, beware of Di Hydrogen Monoxide, it has killed countless people over the years..

  8. I would use the IN HAND 7 inch pipe you have BUT: put 2 sections together and make it a 14 inch diameter flue. Assuming you have the type that is made flat and connects down the side.

    I have seen two of the 5 inchers used for a one 10 inch flue... my new side draft is 12 x 12... brick ala JeremyK

  9. As an electrician I have tubes on the service truck. WARNING metal ends. the metal WILL go through the plastic PVC ends, I know. had to stop fast, I did, the conduit in the tube kept going, right on through the pvc caps.

    the tubes are great. the foam may stop noise, but it won't stop inertia and forward momentum.

  10. 5 ??? ummmmm no. You must have me confused with Howard Clark or Jim Hrisoulas, there are only a few that make blades deserving of those figures.

    I think its the stone mushrooms I used in the leading photo, giving the illusion of a false grandeur. :D I will admit 4, and I should have charged more than I did. But I think many of us feel that way sometimes after finishing a longer than planned project.

  11. Coal forge, and a 4.6 pound hammer and anvil is wastefull the rolling mill I built last year helps. not really 15 pounds, to be exact, 14 pounds 10.5 oz. scale plus the 1/4 inch grinder disk to make the ladder... :(

    After I finish building my new shop, I will build a press. Not to out do the 85 + ton Julius Squeezer :cool: but in the 25 to 50 ton range would be nice.

    But thank you Jim, praise coming from you is a high Compliment. And I used Oil quench
