  1. What Did You do in the Shop Today?

    An ice cube is even better, and can be shaped.
  2. It followed me home

    Mine has not been lined since the late 70's when my Dad bought it. Just avoid any sudden temp shocks.
  3. Clamping for heavy chisel work

    What kind of chisel work are you doing?
  4. Navy Hammer sell off

    I believe I still have the brochures from when Mare Island Naval Shipyard sold off their forge shop. I saw the hammers running during a family day years ago with my Dad who was a nuclear pipe prepping instructor the last 10 years he worked there. Very impressive. If I remember right they all went very inexpensively as the moving costs were so high.
  5. U.S. Army (Cavalry) pack forge

    I will have to dig to find it, but I had a tech manual that showed the forge used in a military mobile machine shop. It was a Buffalo brand, and the the top was a clamshell design that closed over the top when not being used as the hood IIRC That is a neat link Charles. Interesting that the vise is a bench style and not a post type.

    The other issue is shrinkage of the weld bead. As it cools it shrinks and pulls the two pieces together. Size of bead, thickness of the items being welded, alloy (stainless is really squirrely), all affect the outcome. Peening the welds will spread them out and help to flatten things backout. I have seen that done by old school body and fender guys to keep a car panel straight. For sheet I liked .023" bare wire with a gas.
  7. zirconium

    Magnesium is like that. Mill it, chop it, weld it with no problems, but start to saw it and you have to watch the chips as they can start on fire.
  8. Depends on how it was done. Do they have documentation on how it was welded? If not, be leery.

    Nugg3t, my m-715 is all original, but will need some work. It has 28,000 original miles. Many of the fire department ones out West were converted to Chevy 350's. The ones I see today are getting 5.9 Cummins dropped into them. Mine has the original Tornado OHC 6, 5:87 gears , Dana 60 front and Dana 70 rear. Even has the OD green paint.
  10. Ladder Damascus Dies

    My question is how it is used for a ladder pattern? I usually see the billet itself ground out in that fashion, then flattened out.
  11. Brass brushing/coloring

    As to copper you may need the part to be hotter than brass as it has a higher melting temp, and also conducts heat extremely well.
  12. Making a saw blade

    Smoggy, both the Germans and the Swiss made sawback bayonets. Many of the German ones seen today have had the saw ground off as they were deemed cruel and unusual . But as a sapper's tool they provided a long saw. The ones I have seen are all push cut and have a crosscut tooth. C.Baum, yes, we call that field dressing the game. For in the field I would check out the site I posted above as they have some good information regarding using saws in the field. Myself I would think a longer folding type blade would be best as it would allow a longer stroke and reduce the time and effort need to do the task. A thin blade will also take less effort to use as less material is being removed by the blade.
  13. Changing wheels on a bench grinder

    The biggest issue I have with some new wheels are that they have those multi-piece plastic inserts so they will go on many different shank sizes. They do not always run true. And who says that you are putting a new wheel on? I have swapped out wheels to put wire wheels on, different grits, etc.. When they go back on they don't always run true again. At work I am constantly dressing the wheel to remove grooves, rounded corners, aluminum....... It is in a place where anyone can use it and it gets abused. I have brought this up before, but I need to do it again. Some of the mechanics are also the worst about messing the wheel up.. I try to educate them, but they don't listen most of the time.
  14. Ladder Damascus Dies

    Jobs like that are great for a horizontal mill and a slitting type cutter as they are a lot stronger than an endmill, and you can really hog a cut.
  15. Badly ventilated forge

    A maker here in the States for fume extraction is Smog Hog, and I saw a lot of their units at welding shop auctions. Some had a large main unit with long hose arms that you could position near your working area. Even if the ventilation system is not period correct it could just be easily explained as to why it is there and the bad conditions that the workers in the past had to endure if they wanted to stay employed. Maybe also mention life spans for workers back then. Even some big fans pushing the fumes towards the window - if it opens would help a lot.
  16. stone bird

    Kind of like the Common Loon call here that freaks people out. I have some peacock near me that I hear from time to time. Aus, down my way I see stones used on bodies for ants and scorpions.
  17. U.S. Army (Cavalry) pack forge

    Interesting. You would think that if they were looking to save weight that these would have been made as a side blast and eliminate the long blower tube. Maybe just hang or insert the blower on the side instead. Sometimes I wonder about Govt designs, and the rational behind them. . I have a 1967 M-715 one and a quarter ton 4x4 utility truck that came from the Army. It has the usual canvas drop top, custom bed with all of the hangers for picks, ax, shovels, and Jerry cans. I go to slide a sheet of plywood into the bed and it stops short.... I look up front to see what I am hitting, and I am bottomed out against the cab.... A full size truck, and the bed is 2" short of 8'----- BRILLIANT!!

    First thing you need to do is add your location to your profile so it shows under your avatar. This will greatly aid us in helping up out. Jeeps? You and Daswulf will get along then. My Jeep is a 1967 M-715 so not really a capable off road vehicle for the most part.
  19. Ladder Damascus Dies

    That job is easy enough to spin cranks on to get the spacing. That would be a good one for my shaper
  20. Buffalo blower no. 4

    Cast iron , which is a bugger to weld correctly. I have done several cast iron repairs, and some grades are not weldable. Brazing is the safe way to do it. The peg has to be steel to forge as cast will just crumble. Cool looking blower, and it appears to be of a substantial size
  21. Changing wheels on a bench grinder

    Also some general wheel advice. Always make sure the blotters (paper discs) are in place, and do a ring test to check for cracks before mounting the wheel. When starting up, stand to the side for a couple of minutes, and use a good wheel dresser (star wheel or brick) and true the face up.
  22. Colorado Springs blacksmith?

    Well if he gets to Fabulous Las Vegas Nevada I can help him out We are becoming a foodie destination.
  23. Steel for a corkscrew

    JOLT, there is a name I have not heard in awhile. And I prefer the original Newtons. For a corkscrew I might use a straightened out valve spring. Heat to critical , quench, then draw to a purple. As to stopping the color running - a bucket of water works great.
  24. Look through the improvised anvil pinned post.
  25. Found my first anvil?

    Just from the feet I would say Mousehole. Now having said that... if $400 is a major purchase, have you looked through the improvised anvil thread? To be a smith does not mean a London pattern anvil is required. For far less than $400 I could have a whole smithy outfitted. I hate to see you dump that much into a pretty well used anvil and not have anything left over for the other tools. I would bet that you could scrounge up a suitable chunk of steel in your area. 200# should run around $50 or even free depending on where you get it.
