  1. You might try using a torch to heat just the spots you want to drill to a dull red and toss it in some sand to let it cool slowly. That's a low tech mean s of annealing.
  2. Sure. In that case do the design that makes best sense to you. I once scraped down a deer hide with a rig axe (some might refer to it as a hammer head hatchet). I think the idea of the curve is so a corner doesn't dig into the hide and tear it. I used a log that was normally used as a seat by the camp fire. That way the hide was curved rather than the blade. It made for a convenient place to throw the scraps as well (the fire).
  3. Or search for "fleshing knife" images and ask him to select one.
  4. It is amazing how far off topic we can get. I like it! To draw it back a little closer to the original discussion, the part about hand/eye coordination and how some people seemed to grasp spatial relationships and how to manage them (with tools) sounded a resonant chord in me. When I was diving, I found that was usually the difference between a good diver and just another wet body on the time ticket. Ninety percent (or more) of the work I did in my early "mudhole" days was done in zero visibility. I had an accident involving O2 toxicity (that's where I got the "Purple Bullet" nickname ) and couldn't dive deep water until I passed an O2 tolerance test (which I did a few years later - again, another story.) After doing this a while, I could get down to a site, run my gloved hands over everything there, and thereafter I "saw" everything in my mind's eye. I did a lot of hammering on hammer wrenches. Sometimes I had to even use both hands on an 18# maul. The wrench was tied to my harness with a rope so if it fell off the nut I'd know to not swing again until I replaced it.
  5. TP -You are right, of course. I was just curious. There is such a thing as chloride stress cracking but I've only seen that in some stainless steels. Once the company I worked for (a corrosion company no less) had to put a sign up on an unmanned offshore platform. The sign fell off before the week was out because they didn't pay attention to what kind of stainless they used. JHCC - I've seen that in pipe failures as well. In some cases it was corrosion that started the crack and once it had a weak point mechanical failure from fatigue took over.
  6. The only safety issue I am aware of is that iron sulfide is pyrophoric. When I worked in a refinery we had periodic "Turn Arounds" when repairs and cleaning that couldn't be done while running was performed. When piles of wet iron sulfide were left out and started to dry you could see smoke coming from the pile. I never saw it ignite anything but if it is disbursed and not allowed to accumulate it shouldn't be a problem.
  7. I hear a lot about microfractures in old leaf springs. I've made a few (very few compared to most of you) blades from some that were old and even pitted (which I realize doesn't mean it had been subjected to repeated flexure.) I didn't have a problem with them. Once you get those stress fractures up to near welding heat and pound on it, it seems to me it would either propagate, and you could see it, or weld back together and reform the crystalline structure. Is that right?
  8. I went by the Fossil House on one of my motorcycle trips. You are absolutely right, George. I struggled with making the original post because its hard to warn people about something you can't detect without special equipment most people don't have. The only defense we have from something like that is knowledge. We can't let it keep us from enjoying life, though. I'm glad I posted because I think I learned more about NORM than the little bit I contributed.
  9. Masterfully done, Frosty. I never really got into drilling except for one summer as a teenager. I was working as a galley-hand (offshore cook's assistant) on a converted WWII LST drilling tender (ship that held quarters, pipe and supplies for the rig mounted on the platform) and due to an accident they were short-handed. I helped handle the slips (a three part cone with teeth that gripped the pipe and prevented it from falling down the hole) nowadays those are hydraulic operated, but back then they taught me what work is. My deceased brother spent more time on rigs. He once told me that they were drilling in Timbalier Bay and were over a hundred feet down. They suddenly started smelling a fresh-cut wood smell. They checked the mud tank and found chips of cypress wood floating. I guess it wasn't called Timbalier Bay for nothing. I bet you found a lot of interesting things in that career.
  10. ThomasPowers- Especially when you light it and apply an enhanced oxygen source. Say, what if I added a whole lot of sand to my plaster of paris? (Just kidding) JHCC - Good answer.
  11. LeeJustice - Careful, you may be setting up someone with a straight line. ThomasPowers - an attitude I admire and will aspire to.
  12. LeeJustice - I get it. Sorry. When you use terminology for most of your career, you forget that to other folks it is jargon. Produced water is water that comes up with the oil and gas. We want the oil and gas. We don't want the water. ThomasPowers - Yep. Condensate is heavier hydrocarbons from a gas stream that have to be separated out before running the gas through a compressor. Compressors and liquids don't get along well as I'm sure you know. BTW, sir, I've been on this board for a while but only recently got more active due to surgery on my ankle. There are a lot of helpful, knowledgeable folk who post on this board, but from what I've seen, you deserve a rank above Curmudgeon, IMHO.
  13. Garden Banks - a little over 100 miles south of the Louisiana coast. But NORM can be found all over. It tends to aggregate in scale from produced water. Only I wasn't drilling. My dad was the driller. I was producing - getting the stuff out of the ground, splitting it up into oil, gas and water streams and pipelining the oil and gas back to refineries.
  14. After a quick review of Lee's link, (thanks, LeeJustice) I would guess that IF it came from sour service you would still be suitable as long as you ground it down to bare, smooth metal before forging. If you don't see any black powdery deposits (iron sulfide) in heavy pitting then it was probably in sweet service and you are good to go.
  15. That would take a long time with VERY high pressure. Sucker rod is solid rod. The question as I understood had to do with safety of something coming from sour service (high H2S). As I said, I don't think there is a safety issue, but, and I should have added "theoretically" because I've never tried to forge metal from sour service, sulfides MAY be present that degrade the steel quality. Does anyone have any practical experience with this?
