  1. Only ever built one gas forge so not any kind of expert but I think you might want a pass through hole in your door. I wonder where your exhaust is going to go if you close the door and how much heat you will lose if the door is open. I built mine using a compressor tank (aspirated with a single burner) as well but cut both ends off and use soft fire brick to close up the ends. That way I can configure the opening in the front to accommodate whatever is getting heated and the back can also be configured to allow for pass through for heating long pieces.
  2. Folks who reload ammunition have been using vib tumblers for years to clean the brass cases. Typical media is corn cob or walnut shell. You can add small amounts of polishing compound to get nice shiny stuff. I have read where some folks wet tumble with stainless steel media but have no experience there. I don't know about cross contamination between steel and copper alloys but don't think it would be much of an issue.
  3. And that is the answer to what my next question would have been!
  4. Thanks for the replies! While I have heard the term before, what exactly is blister steel? One of these days, I am going to buy a metal detector and give the yard a proper going over as I'm sure that lots of things have been lost or forgotten out there in the past 160 years.
  5. I found this along the stone fence in my backyard of my circa 1860 home. The property has a good size pond and was once used as an ice pond and the bit of metal has the look of a runner on a sled or something. I made the cut with both a hack saw which was going slow as it seemed the material was a bit hard. I switched to a cut off disc in a die grinder which produced dull red sparks with a bit of feathering. There is no telltale linear rusting/pitting that I typically see with wrought iron while the break is sort of fibrous and it did bend so not cast iron (I think) and I wonder if it is
  6. A few years ago, I was cutting up firewood. One big chunk of crotch wood needed sawing before I could get it in the splitter. Killed three chainsaw chains on that piece and when I finally split it there was a melon sized rock in there.
  7. I completely understand about finding space for more useful tools! My shop is a three car garage but the shop only uses two of the bays. Why do I have 4 drill presses? Why are there two anvils? Why do I have three bench grinders? I have a small drop hammer that is rarely used but how can you get rid of such a thing? Same with the Atlas shaper, when you need it, nothing will do the job better. There is also a small antique punch press that I never use and that should go. The trouble is all the stuff that needs to be moved to get it out! I did weld trailer hitch receivers to the edg
  8. Years ago I saw an engravers set up that was a table like affair with the engravers ball vise mounted to a vertical shaft. The shaft extended below to a kick wheel sort of thing like on a potters wheel. This allowed the engraver to move the vise/workpiece in a circular motion with their feet allowing for nice continuous curves on scrolls. Might be a project to consider if you are going to pursue engraving.
  9. A frame gantry hoists are best suited to lifting and loading onto a truck or other means of conveyance like a four wheel dolly - not the best choice for moving stuff around but it can be done carefully. Moving the weight to one side and strapping it to the frame can reduce the pendulum action but be mindful of the weight biased to one side. Large castors for easy rolling are best but do forget about rolling it over rough surfaces. I have ideas for building one myself.
  10. Those blades have diamond bits impregnated in the edge to do the cutting. Who knows what alloy the steel part may be. Like mentioned above, testing is required. A buddy of mine once gifted a great "score" on me. He snagged some very large used band saw blades from his workplace thinking they would be good for pattern welding stuff for knife blades. Turns out they had carbide cutting teeth and the band part was 4140 so not so good knife making material. I ended up making a bow saw out of one of them for a potter friend so she could saw soft firebrick. I used rebar for the fram
  11. That hammer is also a two man hammer - note it has two handles.
  12. An interesting point you have there Geoff! I too have never found a point after many hunting trips, hikes or camping mostly in upstate NY. I've found plenty of other odd things and my hunting buddies always tell me I spend to much time looking at the ground instead of looking for game, but never found an arrow head. I do have some beauties that were gifted to my parents by their landlord when they were newly weds. He supposedly found them on his farm in Waterloo NY and an anthropology prof. that I had in school had them dated as something like 2,000 BC - I wish I had put it in writing. H
  13. The picture above is based on the Beverly shear which will curl narrow cut off portions. You don't say how wide your cut pieces will be but in my experience cutting a 1" wide strip from a larger piece (your 8x36 piece) the 1" wide would curl to some degree. If you need mostly straight pieces, take your large piece to a sheet metal shop and have them shear it for you in a squaring shear or what many call a stomp shear. I have an electric hand held shear that would probably work but the kerf is probably 1/8". I do wonder about the plasma torch. Other than the slag, what problem would th
