  1. Newbie Shop Story

    I really like your side draft chimney, it looks just like mine! My coal forge is outdoors so the chimney works great when there is no breeze but I have to add wind breaks when a breeze comes up.
  2. Ground Rods

    I think I will just cut them up in little pieces on the band saw and tack them to a base plate in a circular pattern for a basket/pot. I'll make them uneven for a more interesting look. Keeping them out of the forge will retain the copper finish too, except for the cut ends .Maybe save one for a weather vane pole as Don suggested. It's been a long, hot summer here and I didn't do any metal working except some sheet metal, finally cooling a bit and I am getting ready to spend some time in the shop. It's still near 100 but I am getting ready.......
  3. I have a bunch of these ground rod pieces, hate to toss them, any ideas what to make with them? They are 5/8" steel with a very thin copper plating. Varying lengths from 3 to 5 feet.
  4. Hot climate shop advice needed.

    It is nothing more than a big fan with a water soaked media, does not need to be in an enclosed space at all. In fact if you close it in too much the humidity will rise. Needs to draw in fresh, outside air and plenty of exhaust. When used on a building it is a constant air changeover, CFM in = CFM out otherwise it will be inefficient and create high humidity in the enclosed space. As far as being small that is why you use one from a house, not the store bought shop models. Mine will give you chills when the outside temps are in the hundreds.
  5. Hot climate shop advice needed.

    I work under a tin roof in the Southwestern Arizona desert. I got a used 4400 CFM side draft swamp cooler and put it up on a stand with casters (free stainless steel rolling stand thrown away by supermarket), put a garden hose hookup on it and a j box with a rotary switch and plug in cord. Hardware cloth over the squirrel cage opening to prevent finger chopping accidents. I can place it just where I need it so it keeps me cool and doesn't blow on the forge. The stand I used is tall enough to keep the breeze on my upper body. Works great and I couldn't work in the summer afternoons without it. There are store bought "shop coolers" but they are expensive and do a poor job IMHO.
  6. A chandelier of that size and weight warrants a lift. Once the lift is properly secured to the structure the fixture can be installed, cleaned and serviced easily. Among the more well known makers are Aladdin and Peter Albrecht.
  7. I went to get my card at the last minute and I was afraid they'd be out. Then I realized when I got there and the whole card aisle was mostly guys there would be plenty as most of us guys wait till the last minute.
  8. Stove Pipe Roof Penetration

    Don't know if you did it yet but I put a 8" Chimenea pipe thru a corrugated metal roof almost 20 years ago and it is not leaking yet. I simply got the flashing then used a tube of GE Silicone on the uphill side and pressed it down. Don't try to seal the downhill side or it could trap water in and leak. I've had some roaring fires in that Chimenea over the years and the pipe immediately above it has gotten sizzling hot but the silicone is still holding. The silicone also is rubberized so it gives for expansion instead of cracking like plastic roof cement.
  9. Heating source for wedding knife set

    for wire sizing and voltage drop loss calcs yes but for total power consumption no, In a resistive load like a heating element Amps X Volts= Watts so end cost is basically the same minus VD losses on the 240 volt circuit. You can't get around Ohms law.
  10. Stock holding idea

    heh heh well I am not calling myself a blacksmith just yet! I do however have a friend who is quite accomplished and I will ask him to assist me when he has a little time.
  11. Stock holding idea

    I have a terrible time with my tongs. From the fire to the anvil I usually lose a lot of time fumbling around trying to turn the work piece how I need it, sometimes dropping it, losing heat as I fumble around. All my tongs are used flea market bargains except two pair of Wolf jaws. I am thinking of ordering some quick tongs and make them to fit my work better, but mostly right now I think it's just that I haven't practiced enough and my coordination is not that great anyways. I have considered just welding rebar onto my pieces but resisted thus far because if I do that I will never get the hang of the tongs, plus that's a PITA anyways.
  12. First firing today

    Finished the forge today and fired it. I didn't time anything but it did get hot pretty quickly and once warmed up it had no trouble heating my test pieces. It's got a real good swirling effect. I noticed the hottest point seems to be the side opposite the wall that the flame rolls into. It seems to roll along the floor, up the wall and across the roof, down the other wall and develops a hot spot right as the tip of the flame hits the floor again. The front 2/3 section seems to get hotter than the back, I might try aiming the burner toward the back a bit. I have the burner recessed about 1.5" past the Kast-O-Lite and into the ceramic blanket liner. Now I need to study up on making the flame optimal and efficient, and build an idle circuit. svid.mp4 Tried to put in a short video, not sure if it will work
  13. Id? And I messed up my stand build!

    Well it seems my 3 foot diameter piece of 1/2" plate walked (or rolled) away. I knew right where it was for the last couple years and went to get it today and it was gone. I still have some 3/8" ones but I really wanted to use 1/2".
  14. Id? And I messed up my stand build!

    Looks pretty heavy duty. I'm torn between using steel or wood for my upright piece, I have a big chunk of 12X12 fir 36" tall that I could secure to a 36" diameter 1/2" plate I have using some big 3/16" straps I got for free yesterday. Or I could use some 8x8 sidewalk drain I have also and make a plate top. I wonder if the wood would offer any advantage?
  15. Oh we use Scotch 33 for anything important but for pulling wire and temporarily bundling home runs for easier handling we use the cheap stuff.
