    Sculpting hot iron on the power hammer, walking the dogs on the beach, drinking good single malt scotch at happy hour with friends, eating fresh seafood, reading mindless adventure novels, and spending time with my beautiful wife. I forgot...making money at blacksmithing!

  1. Hello, my name is Andy and I am trying to decide on which power hammer that I want to build. I was watching your video on the new style Kinyon hammer and was wondering how you were liking it and if you would change anything since you have been using it for several years now? Also I was looking at the Clontz style tire hammer and wanted to get your opinion on the pros and cons of helve hammer vs tire hammer. Any advice you can offer would be greatly appreciated. Almost forgot, how large of a compressor do you need to power your hammer? Thanks Andy

  2. Hi, I haven't been posting recently, but still look at the pics. I have a suggestion for warping based on the machinery I have in my shop and the school of hard knocks and wasted steel. I start by profiling the blade and bring the thickness to about 1/8" for chef blades. This is where I heat treat. I heat the blade to 1500 deg (1095-15n20) and quench in AAA at about 120 deg while agitating up and down for about 10 seconds, then immediately place the blade between 2 pieces of 1.25" aluminum plate and apply pressure. I have a hydraulic press which makes the process easy, but heavy weights will work. I flatten one side then flip the blade and do the other. No edge grinding is done until after tempering. If you still have warping, repeat the heat treat. Another mitigating factor to minimize warping is to thermal cycle several times, normalize and anneal.
  3. Jph, Are you dry welding by using a tig to go all the way around the billet? 440 and what other alloys? Thanks, john
  4. Just a couple of suggestions for finishing: I use 3M film backed belts that come in micron sizes...60, 30, 15, and 9. These are used for polishing and not stock removal and are relatively inexpensive. I usually buy online from TruGrit. The 9 micron will not give you a mirror finish, but close to it. I then use a cork belt loaded with the white compound to polish the blade from there. Some smiths say to not polish before etching as they think it muddies the etch. I haven't found that to be true. I wipe the blade using lacquer thinner, then scrub with 409 and scouring powder before etching. I etch using ferric chloride that I buy from MicroMark (on line). Their ferric is much stronger than R.Shack and about half the price. I dilute at least 1:10 distilled water, sometimes greater as I like a slow etch. After 10-15 min, I pull the blade out and sand it with 2k grit paper and Windex. This polishes the more noble 15n20 highlights, then back into the etch. This is the only hand sanding I do.. When finished, I neutralize by scrubbing with baking soda on a sponge, then rinse with water and spray Windex (with ammonia). I never grind using 36 grit to start. It will leave micro scratches the never seem to come out. Also, I have work lights on my grinders use halogen spot lights. They make a big difference. Steel that has been heat treated will etch differently (better) than than that which hasn't been. Hope this helps. John
  5. That is beautiful! If you haven't already, you should also post this on Kevin Casey's "feather damascus steel" on FB. Outstanding work. Looking forward to seeing more. Thanks, John
  6. Another suggestion would be to buy a pid reader and thermocouple to manually control your forge temp. Weld at 2315-2330 deg and forge at slightly under those temps. Soak time is also important for consistent results. John
  7. I feel for you...it happens. But the good thing is that you learned what not to do. That's a good day. John
  8. I made one of those jigs as there are enough vids etc to figure how to do it. It works fine. That being said, I went back to free handing as I felt I had more control. fwiw. Also, the cost of the jig if you don't make it, is astronomical. I always have a desire to challenge my skills doing it free hand. John
  9. As an 'old guy', I never try to discourage anyone making knives, and always try to encourage those just beginning the journey to the 'dark' side. Why it's called that, I don't know as I've been a blacksmith for the past 25 yrs and have fallen into the abyss...happily. The challenges can be monumental including one to understanding more metallurgy then would be normally associated with blacksmithing. That being said, I think neck knives are a complete waste of time. I cannot think of one good reason for one to carry a knife around one's neck. Personal safety?...hmmm...probably not. Too easy to be disarmed and turned against the carrier. Convenience? Probably not either. A sheath on the the belt will work just fine and not get in your face by flopping around. This seems to me to be a trend that someone thought would be really 'cool'. I'm not there. Those who carry, convince me. John
  10. This is tough for everyone. I used to sell in a store that charged a 25% commission. I could live with that. He never sold much and has since gone out of business for various reasons. So now, I'm left to my own devices in marketing. No one sells my knives better than me. I have a shop and gallery of black smithing and blade smithing items. I ALWAYS make it a point to walk people thru the shop so they are aware that all items are hand made and what it takes (machinery, forge etc) to make them. Ultimately, they ask what I am working on now. This is my 'in' and I change the subject to blades which I show and speak of enthusiastically. That may not sell the knife immediately, but it puts the idea in their head that it may make a great present, or for current usage. What you should charge for your blades...getting back to your question...is probably worth more than you think they're worth. Most folks don't understand what goes into making a blade, so the onus is on you to do the education and express your love of the art. You have to sell your art. Over time and feeling out your market, you will come to a consensus regarding price and time making your blades. Give yourself time and aim high. There is nothing worse than selling a blade and thinking afterward that you took in the shorts for all the work you put into it. Just my 2 cents. John
  11. Just thinking that maybe you should start with a more modest pattern with goals that are attainable. john
  12. Cruising around and coming on this late as usual, but have some suggestions: Using a propane forge to ht, buy a thermocouple and a pid temp reader to manually control the temp. A needle valve for your gas line will refine the process. Prior to the quench, I like to thermocycle 2-3 times to refine the grain, then I normalize for stress relief. This seems to minimize warping. Soak time is important. I like to heat to 1500 and soak 5 min prior to quenching, especially with 1095/L6 combos. 1095 is a hypereuctectoid steel and is not very forgiving. By doing this, I consistently get 64 hrc, then temper back. There are no shortcuts for consistency. I tried. John Gearhart Ironwerks
  13. Yep, Craigs List. Start watching it regularly. They do come up frequently. A front loader would be ideal. Good hunting (which I think is part of the fun). John Gearhart Ironwerks
  14. Not my problem. It is loud! It's an ocean front house so probably not many going by. It's a bit staid in Cannon Beach, OR. John
  15. Been working on these all week and finally got them handled. The top blade has a thuya burl handle, the middle is desert ironwood with an ebony bolster and the bottom is snake wood with an ebony bolster. thanks for looking. John
