  1. The cross pein hammer, aka blacksmiths hammer is very handy, but sometimes a straight pein is better for a certain job. Needing a straight pein in a hurry one day, I took an engineers hammer, left the handle intact, locked the head in a vice, and using a hand held grinder with a cutoff wheel, cut the head to the shape of a straight pein. I cut carefully, to not raise the temperature enough that it would "lose its temper" i.e. need to be rehardened and tempered. I then finished shaping the head on a belt sander, giving me a usable tool, far faster than making one from scratch.

  2. For iron, you would have to find it laying around somewhere or in a junkyard. No one really sells it any more. Mild steel is available from Steel Service Centers, in volume or from a local welding shop for small amounts.

  3. Hey, GrayR, glad you are here. I asume you are grayer than most, but my beard is white too. It is tough to join a new group, and get the instant recognition you most likely deserve. I know, I joined this one recently. Sounds like you've got a darn good grasp of metallurgy and this is a good place to share it. Ed, as an example of what I think quench crack means, I once found a drive shaft from something, 1.625" by about twelve feet. I knew it was tool steel from the drive spline. I have made a great many blacksiths tools from that one bar, and still have about 3' left. I am not sure what it is but am able to harden it readily. In another case, a customer comes in with a tool a freind of mine made 20 years ago, just before he died suddenly. The customer claims the tool is too soft and wants me to harden it for him. After checking the hardness and thinking for a while I agree, but I have no idea what this stuff is, as my freind died before he ever told me what he used. I agree with quenchcrack, write a blueprint. I make my living doing this and the more we all know the better.

  4. High freg converters of the type you are using have an adjustable spark gap under a flap some where or behind a window. Yours may need an adjustment. I also sometimes remove a gfi and replace it with a regular outlet, unless it is by a sink. By the way if you have one gfi in a circuit, all the receptacles in that circuit, become gfi. As far as being broadcasters, that is exactly what they are. They are used in tig welding to broadcast a beam of electrons from the end of the tungsten to the work, that the welding current can then follow, illiminating the need to "strike an arc". High freg has the aditional benefit of helping to break through Al-oxide, which is why there is a start only setting, for welding on dc. If you want to witness the broadcasting ability, point the tungsten at your finger from a half inch away (do not ground yourself) and step on it.

  5. But in reality an extra 50 to 100 degrees will do more than another twenty minutes at soak.

    True, but the center of the metal in question will not get 50-100 degrees hotter unless it soaks long enough anyway. Long enough soak time is equally important as temp, for if either of them is inadequate, proper hardening will not be achieved.
  6. Shopping at the local industrial junkyard, I picked up a 30 gallon stainless steel barrel, and a ten gallon s.s. can, almost as big in diameter. I drilled a bunch of holes in the can, attached a bail, and it sleeps in the bottom of the quench tub. Now when I forge a bunch of rivets or whatever, I just drop them in, and when I'm done, lift the can out. I made the bail extra long so I don't have to stick my hand into the water. On the side of the quench tub, I welded on a rack to hold the few tongs I am using at that time.

  7. When I first found this site I read a lot of the blueprints and I have to say, nice work, and thank you. But, I look to this spot every day, and nothing personal, but I am not interested in crowd control. How about some shop tips now and then? I will start with something simple, which many of you probably already know , but maybe get the ball rolling. When I need to make a simple jig for hot bending, I use a piece of angle iron as the base. Then when I use it, I just clamp the bottom leg of the angle in a vice. If this is a repeat, please ignore.

  8. I just wanted a better looking weld. Ten Hammers, if you have a dc stick welder, you can get set up with a gas cooled tig torch, and a little juction block (can't remember the right term for it), argon hose connects to one side, torch to the other side, and weld current, and scratch start tig all you want. Make sure you get a torch with a gas shut off valve built in. Should be around $200. Of course you will also need tungsten, filler rods, an argon regulator or flowmeter, and an argon tank.

  9. Fabbing up a medium end indoor railing today. Often mig weld, them spend lost of time cleaning up. Always wondering if I should spend more time welding(tig), and no time cleaning. So today, I sprayed some mig filler in there, then went over it with tig, fusion only, washed the welds around, beautiful result, no clean up at all. Yes I use anti-spatter spray, etc, but nothing looks as good as tig.

  10. I was working as a millwright in a lightbulb factory. I was buiding a new hopper for a drum grinder at the end of a reject conveyor. I had snapped a padlock on what I was told was the correct lockout. While I was standing on the drum, in the grinder welding, a computer engineer decided to start testing programs. I got out of the grinder, just as it came on. Uninjured but shaken, I didn't even bother to pick up my tools, headed for the door, and never returned.

  11. For a beginer, The complete modern blacksmith is an exellent book. Easy to read, easy to understand, beautifuly illustrated, very complete, shows how to improvise any equipment you don't have, insirational. A good follow up would be Bealer's Art of the Blacksmith.

  12. By the way, you can blow up a battery with welding current. I can't explain how this happened, but with the welder on, I connected the ground clamp. The stinger must have been in contact with the body or the bed of the truck. As I walked arround the front of the truck, with the hood open, the battery exploded in my face. But for the grace of God, I suffered no permanent damage. I dove face first into a snow bank, and by the time I was standing up, a mechanic grabbed me, and got my face under running water inside the service station. I will never weld on a vehicle with the battery connected no matter how many times you say that nothing will happen. Been there, done that.

  13. My first car disaster involved an aprentice who cut through a gas line with a torch. Complete new interior, I picked up the tab. Second time, replacing a section of frame, some type of tarred felt glued to the inside of the sheetmetal body, about six inches away from where I was welding, ignited, causing paint and again interior damage. The car owner was a machinist who was very understanding, but I still had to pay for the repairs AGAIN. Will there be a third "accident" ? I hope not.

  14. Afraid I have to agree with irnsrgn of this one. If the time it takes to undue one battery cable is too much to spend, then I guess you can readily afford to repair whatever damage may occur. Just because you have done something without ill effect, in no way garrantees that you will always get away with it. There is a concept that is a bar to all knowlegde; that concept is contempt prior to investigation.
