  1. Grey iron is still much more brittle than properly heat treated cast steel. Millions of tools have been made in anvil hardy holes. If you are really concerned make a support for the tail of your anvil or make a upsetting anvil like Brian Brazeal

    I did make one its 4 inches sq with 1" plate on the top and bottom with a 1 1/4 hole on one side and a 1" hole on the other the holes ae blocked in on each side with 3/4 stock welded in place before the bottom was welded it weights around 25-30 pounds

  2. I just sent you a price on the shipping for the swage block. Sorry about the delay, I got a price from fedex right away but was waiting on a price from a trucking company as they are sometimes cheaper for the 14lb blocks.

    I assume you have read Mark Asbury's recommendation to use a swage block for upsetting hardy tools rather than using the hardy hole in your anvil. Personally I have always been puzzled by this and disagree with this suggestion unless you have a particularly light tail on your anvil. Most older swage blocks and a lot of newer ones are gray iron which is much more brittle than wrought and tool steel in an old anvil or all steel of a newer one. I have upset quite a few tools in the hardy hole of my anvil which has a fairly thin tail with no ill effects. Yes there have been a few over the centuries that have broken at the hardy but I don't know anyone who has broken theirs. Most hardy holes are and square holes in swage blocks are not exactly the same size. Forging in the anvil the tool will be used in will ensure it fits exactly.

    If the idea of damaging your anvil really has you worried, Brian Brazeal has a thread on here on making a striking anvil. Or a striking anvil could be laser or waterjet cut out of a chunk of heavy bar or plate.

    correct me if I'm wrong here but Mark says that because he uses a Brooks anvil it's made of cast steel. I believe he's said he has seen them split at the hardy hole. the brooks has a 1 1/4 hardy hole
  3. The Spruce Forge "manual of Locksmithing"A Blacksmith guide to simple lock mechanisms by bill Morrison and Dennis Frechette
    ISBN 0-615-11822-4
    shows tools needed shows how to make Pipe locks,Spring lock, Trunk lock, Cupboard lock, Door lock, Gate lock.
    I got my copy from Nation Builder Books ,PO BOX 253 Leesburg, VA 20178 ,800 480-5808; www.NBBooks.com
    I believe you could adapt the information in the book to make what you want.

  4. use a small drill to drill a series of small holes around the edge and use 1/4 chisel to cut the web away also drilling a hole in the center helps to let the chisel move the metal out of the way ...a small chisel works a lot faster than a larger one

  5. One of the guys in our Guild is looking into having some anvils cast ...on checking in Anvils in America I see where in the past anvils were cast of Vanadium steel,4140,4130,8630,ductile iron.,and H13.
    anybody have any suggestions as to what to have them cast from?

  6. it hasn't been mentioned yet but keeping your file sharp is important also. one problem when transporting them is that they bang together or against other hardened steel. what I started doing was making a cardboard sleeve to put them in, awhile back I was in Tractor supply and found 1 1/2" flat blue water hose sold by the foot I now use this cut to length to cover each file ...
