  1. While I have heard that using acetylene rated stuff is not compatible with propane, I have been using standard oxy/acetylene hoses for my propane/oxy rosebud torch now for about 40 years with no issue. It was what the local welding supply place (Jackson Welding) sold me when I bought the torch. Perhaps the oily stuff was something left over from when your torch set was made if it is a new set up.
  2. Pitch is probably what you are thinking of. There is also dop wax used in the lapidary arts to hold stones while grinding and polishing them. Both are heat sensitive so hand sanding or wet grinding only.
  3. What are the advantages of a vertical forge?
  4. I believe that is a lead file. Years ago in a pre bondo time, auto body filler was lead. The teeth of the file could be easily cleaned if it got loaded up.
  5. Watch what these guys do and consider the safety precautions they have taken!
  6. I would bet most of work on the Paley gate was done on the Nazel hammer and I would also bet that most of the pieces with the hair pin type features are actually two pieces and welded and ground to give the appearance of a one piece element. Not to say those kinds of texture couldn't be done with a press and the C frame would be more flexible as to accept work that could fit.

  8. I found this at a yard sale on Sunday for the princely sum of $1. Looks to be a very specific type of burner and checking the web site of the maker shows they make a bunch of different types of heaters but show no pictures of their burners. I don't know if it is set up for propane or natural gas and if the later it is not so useful to me as is. Anybody have any ideas? Could it be used to make a small forge? The regulator came from a different online auction and may be useful to supply gas to the burner - I haven't researched the intended use of the the regulator yet.
  9. Undoubtedly, my house had some kind of coal furnace in past as there is the remains of a coal bunker in the cellar. I've never seen a tong like you describe but perhaps it is buried somewhere in the yard lol!
  10. I'm quite sure that the donut shape is cast iron and think the flat part is as well. As far as I can tell, it is just a recess in the middle but the corrosion could be hiding vents/orifices. If it is tuyere, how would it deal with clinker? My only experience with coal furnaces is when I would visit my grandmother in the winter and hearing her crank the shaker grates in the morning. I'm planning on dragging the sandblaster out in a couple of weeks so the hammer will get done then. Might blast the unidentified cast iron thing too. I now wonder more about what treasures are buried in my yard.
  11. So back in the yard again and had to dig a hole next to the ice house foundations which are poured concrete so not very old. I was using a backhoe so I was able to get down three feet or so no problem and as I dumped a load, I saw this strange shape thing fall into my pile from the bucket. It at first looked like stone and my mind was seeing one of those stone Celtic crosses like what I had seen in Ireland. After banging on it with another rock I realized it was iron and so took it back to my shop and went at it with a chipping hammer. It is 14" tall and seems to be two pieces, one a hollow donut shape with a hollow tail and the other piece flat. I thought maybe a burner of some kind but so far no evidence of any gas holes. Anybody have any ideas? Then today I walked by the excavation which had been mostly filled in and decided to pick the bigger rocks out to add to a pile when I picked one up and thought it was a piece of brick until I realized much to heavy for that, A bit of work with the chipping hammer revealed a cross pein hammer head which I think is wrought iron. I am guessing these would have had steel faces and peins correct? It weighs 2lb 1oz and I plan on hanging a handle on it and wonder about cleaning it up. A bit of a soak in muriatic acid maybe? I don't want to grind on it except for the faces. The wedge was still in it which was king of U shaped and definitely wrought iron but it basically fell apart along its grain. Funny how simple things like this can make excitement in your day.
  12. 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.
  13. 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.
  14. And that is the answer to what my next question would have been!
  15. 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.
  16. 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 cast steel? It's about 1/2" wide and maybe 3/8" thick.
  17. 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.
  18. 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 edge of my welding table so that some stuff can be swapped out as needed by mounting them to bits of square tubing that fit the receivers. Just have to find a place to store the stuff.
  19. 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.
  20. 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.
  21. 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 frame and relied on its springyness to keep the blade tensioned. Worked very well.
  22. That hammer is also a two man hammer - note it has two handles.
  23. 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. He very much wanted to keep them. I'll get some pictures up after coffee.
