  1. I stabilize with a vacuum chamber and cactus juice. This burl is VERY old, and has a lot of spongy, almost rotting wood in it. So it it a resin similar to plastic-ish. I have used HCl to etch, but it can be more challenging to get the concentration just right... ive gotten ‘pinholes’ in the nickel layers where it seemed to pick a spot and eat through. I don’t get that with FeCl. Plus the HCl makes more noxious fumes. When diluted correctly it has about the same (to me) topography changes but often leaves the darks a more of a gray color to me. I do not heat the FeCl, bit if I lived where it was a lot colder I might get it up to 80F if it was just not getting the job done. Pnut, As for the amazon reference, i was just being funny...
  2. Right on! my buffing wheel seems like 50-75 layers of soft linnen, with concentric rings sewn about 1” apart, its a 7-9” wheel. The last sewn ring is about 1.5” from the outer layer. Been a while since I posted here, forgot the commercial link rule... lol But to know which one I use for research purposes, one could search the “South American rainforest’s major river” for “MG Chemicals Ferric Chloride Copper Etchant Solution, 4L Liquid Bottle” and do just fine.
  3. Sure thing. My ferric chloride was originally a 1 part concentrate (exact concentration can vary depending on the source) to 3 parts distilled water. My ‘concentrate’ is this : [commercial link removed per TOS] over time and etching many blades it has undoubtedly diluted some, and I have topped it off with a guestimate of additional FeCl and H2O. Temperature counts, its a chemical reaction and as such is rate dependent on temperature. Warmer means faster etch, not always a good thing, sometimes slower is better. I etch in this for multiple 10-ish minute sessions, usually 40-60 mins total. At the end of each time period I sand, without a ‘hard backing’ just a rubber gloved hand, until most of the black is gone, then back in the acid. I usually use 1500-2000 grit for this light sanding, very little pressure. I do this until I can run my fingernail over it and feel topography changes. Once ‘deep’ enough I rinse and dry it off. Bolder layers I go with a deeper etch, smaller/finer layers not as deep. Then I EXTREMELY CAREFULLY (I cannot emphasize this enough) run it under a buffing wheel with green compound. I get it ALL mirror finished and shiny. There is NO black at this point. [Buffing wheels are NO JOKE, they will rip it out of your hand and fling it 100 feet, or worse-into you, before you know you’re not holding it anymore! NEVER feed it a leading edge, always a trailing edge, and always feed the part rotating away from you, never toward you!] IMPORTANT: the buffing compound is wax based and will inhibit any etching after using it, clean it well. Last for contrast I use instant coffee... the cheapest gut-rot crap Walmart sells. I don’t measure, just make it strong enough that in a 9X13” baking glassware I cant see the knife through roughly 2” coffee. I soak it in this for usually about an hour until its black enough for me, checking every 15 minutes or so. I Dry off then oil with whatever you prefer, then I like to bake it at like 250 Fahrenheit for about 10 minutes. It seems to get the oil to spread, stick, and coat better, i dunno? The coffee doesn’t really discolor the 2% nickel layer like the FeCl does. Or maybe it just takes a lot longer? Thats it. I lightly rub with a paper towel after cooling off. For bold lines, sanding with a hard backing might keep it only hitting the high spots and leaving the darks, well... darker. Here is a closeup the bolster area of a lower layer count with the exact same process
  4. My latest work. 300-ish layer ground then flattened ladder pattern. Was a real joy making this one. 1084 and 15n20 Ive been drying this oak burl for 18 months now, and it is finally dry enough to start stabilizing and using for handles. I LOVE the contrasts I get on it. Etched in FeCl for topography, then took it to a buffing wheel and got it SUPER SHINY, cleaned off the waxes from the wheel then etched for contrast in instant coffee. Makes the nickel layers really shine. Pushing the pin through while gluing the handle popped a little chunk out right here :/ filled it with epoxy and just carried on. Smooth to the touch.
  5. Update: 2019, made another one, specialized for opening seals on powdered antibiotics.. basically a hook and a one sided edge. Made for a pharm school classmate that was a pretty good friend in school. Less drastic pattern, more organic. Made from scrap/end cut off from larger billet. I’m a fan of using as much of me steel as I can. Handle is olive wood.
  6. Both my propane forges are ‘plumbed’ with standard ole rubber propane hose. I would like to change it out for a hard metal line, I was showing someone some basics when he inadvertently bumped a gas line with yellow hot steel... My first thought is automotive brake lines, with appropriate adapters. Thought Id ask the collective here what you use for hard metal gas lines?
  7. Is it possible to get a small trailer? I picked up my Anyang 88 in Decatur Tx, and live in southern AZ, it weighs right around 4000# I used a trailer used to transport scissor lifts. Also, I used chain boomers... made sure the thing was not going ANYWHERE.
  8. I really DO recommend the internal pipe sanding, at least a little bit to: A. Clean up any oil or oxidation or crum that might be in there. B. To clear off chrome oxides then force the HC rod in making good contact. GOOD LUCK!
  9. Right on. Go ahead and try a few different inner cores if you have the time/resources, post results. I only had 2x12” sections of pipe.
  10. I had success with a heavy walled 316 stainless pipe, 1" outer diameter, 0.74.." inner diameter, and a piece of W1 round stock at 0.75.. I took a 1/4 round mild steel rod, cut a slit on the end, then put a piece of 50 grit sand paper in the slit, chucked it in a drill and bored the inner diameter of the pipe until the W1 round would just barely fit with some 'gentle' persuasion. once the stainless sleeve was on, and flush on both ends, I mig welded it completely around both ends. effectively making a canister, with the 316 on the outside. Heated it to welding temp. I judge it by color, to me its a bright yellow... use whatever you want, you could even slap some borax on the outside to make sure its bubbling vigorously just to use as a temp gauge, not needed for the weld, just a temp indicator. Took it to the power hammer and away I went. hammer to shape, hammer in bevels, grind through the stainless and expose the W1 cutting edge. I had to experiment with the quench. I had to use a slower, room temp canola oil. I cut some test pieces at 1/2: wide, 1.5" long , ground through the stainless to make a bevel exposing the W1. I tested in Water, Mcmaster carr quench oil, heated canola, and room temp canola oil. The room temp canola is the only one that didn't crack the W1... I think the stainless cooled and shrunk quite a bit, and it actually pulled the W1 apart, the welds held, but the w1 ended up with a crack in the middle of it, like it was pulled in 2... lol
  11. This is a post of mine, my first foray into cable, not great, but not terrible either... . So... for the NEXT KNIFE you make out of this cable, to get the pattern to show up, no adding up the layers, just get it solid, then shape a knife out of it, standard etching will show it off, plenty of threads explaining how to do the etch.
  12. I thought it was in decent shape. I will take a wire wheel to parts of it that have accumulated dirt on it, that can trap moisture and promote rust, plus clean up the screw... other than that, I will just get her back to work!
  13. I don’t know my post vise anatomy that well, but I’m assuming this is the screw box? gotta love the stand/table/thing the old man kludged together.
  14. Story time, always makes things more meaningful right?: My grandfather passed away, and many of the family wanted to add something personal with him in the casket. My grandfather was always very proud of his lineage. We can trace the McEuen name to the 1600’s in Scotland. There is even a McEuen castle. So my mom, aunts and uncle got the traditional McEuen Tartan made and laid it with him. I decided, in the 6 hours I had available over 3 days to make him a Dirk. He once told me he liked them because they were usually fairly ‘beefy’. More than that, he loved the interesting history behind them. I made a low, 26 layer billet and instead of forging bevels like I usually do, i did pure stock removal, so to have even-ish layers. I had a piece of 2700 year old bog wood (oak i think) from Scotland that made the handle. I know its not really the traditional handle style, but with what I had and time available it was what I could do. The yellow name is sort of a family/friend inside joke, plus a little endearment. Every piece of equipment, old jeep, welder, vise, swamp cooler, etc ... he would get a yellow or white fabric paint pen and write his last name on it, sometimes a year too. I took a picture of one signature on a mig welder he gave me, and my wife used her craft cutter computer program to trace it exactly and cut it out with vinyl. We thought it was appropriate. He was a great man, and taught me so much. He will be missed.
