    Case Hardening

    OTOH the clay is not important. I've case hardened using thin walled steel pipe filled with powdered carbon donors with wrought iron buried into it, One end was sealed and the other folded over a couple times---semi loosely so it wasn't subject to popping---tossed it in the forge and kept count of the hours at heat.
  2. Somehow I feel that he doesn't have a shirt for my surgery, one rather common for men past a certain age...Good to see you back here and on the Green Side of the Sod!

    Hay Budden / Hercules ??

    Anything on the front of the feet under the horn? OLD is probably part of Solid Wrought found on a number of different anvil brands. Where are the pictures???

    Seax Question

    There are a number of sagas that mention taking a sword from a famous warriors tomb just for it's "special powers". With that I would think you might purposely damage a blade to prevent such thefts rather than preventing supernatural vengeance...example the sword Sköfnungr

    Can a ferrous blade be used in a non-ferrous cold saw?

    Any differences in speed or kwh? What does JET say when you ask them about their product?

    Belt grinder advice..

    Someone ought to tell DeWalt that their equipment is being misrepresented on the web by this person and might cause a lot of folks to be very upset with them...

    Belt grinder advice..

    Ditto on the Bogousness of the "ad". Person that thinks that is a suitable knifemaker's grinder hasn't used one!

    Need help with brazing torch

    We were generally working with nickel silver and use the jeweler's hard solders: soft, intermediate, hard. I've used stay-brite for items not as critical as parts for multi-thousand dollar blades. Getting the right flux is important too and you do know that some brass alloys are very difficult to work with---like some of the bearing brasses and leaded brasses.

    Help with new shop design

    It's rather like designing a kitchen. The important bit is the work triangle: Forge to Anvil to Postvise. For general small work you would like the anvil to just be a turn or a turn and a step away from the forge, The post vise can be the same on the other side or if not used as much, another step out. For Larger Work you need to experiment with the size of stock you will be moving through the shop on a regular basis. My basic suggestion is to get some chalk and chalk out the dimensions on a driveway and cut some cardboard to the size of your equipment and then lay them in the chalked outline and move them around while maneuvering a piece of stock to see what works. (I would also suggest not bolting anything down till you have had a chace to actually use the shop a while.) Don't forget to take in account common wind directions and water flows when it rains! (My shop has the main 10'x10' roll up doors along the common wind flow in our valley, ventilation is generally NOT an issue! Helps with cooling too.) I built my shop in two goes (so far!) and have a clean shop and a dirty shop with a roll up door between them.

    Excentric press to power hammer ?

    A press that can't complete it's stroke is a bit like a mechanical bomb with the "boom" parts usually right in your face. Have you looked at building a tire hammer?
  11. Do I need a 16 passenger van or a dump truck or a commuter car or a 4WD? Kinda hard to answer questions like that with no information on what for and how much you need to use it. Kind of annoying to be asked questions that do not have enough information to be answered well. So the basic easy answer that many of us have gone with is: Use Propane!

    Mud quenching?

    quote: steel is the most poor of metals today due to recycled metals added in the smelting process" "This is why we can get single crystal turbine blades and aerospace grade metals and metals suitable for implants in human bodies..."

    Need help with brazing torch

    We would hard solder chapes and throats. A local community college jewelry making course is EXCELLENT training for doing such work.

    Show me your anvil

    I had a bud vase turner turn up at my smithy once. He wanted to make some curved shaft holders for carbide metal lathe bit inserts. So I stuck some appropriate stock in the forge, heated it up and stuck the end in the vise and told him to bend it to suit himself. He grabbed it and hunkered down on it and overbent it terribly! I told him to just haul up on it till he was happy, which he did. Next weekend he bought an anvil off of me...Since he was using the carbide inserts for the cutters and the springiness (YM) of pretty much all steels is quite similar and he should never be getting to the set point! He didn't need fancy alloys and persnickety heat treats.

    Arm and Hammer IDentification

    My 91# A&H anvil tends to sit next to my 469# Fisher just because its thin heal is so useful for so many things!

    What did you do in the shop today?

    A nice wide hardy can make lining up the cut easy to trim them to match. You do need to either angle the long one a bit more so it is a tad shorter so when you forge the new point out they match, or if the cross sections match you can file the cut one to a point.

    Farrier Hammer I.D. needed

    I didn't see one like that in the 1897, 1905 or 1908 Sears Roebuck catalogs so not a popular model, I checked a couple of antique tool collecting books as well. No Luck---which is strange as I've seen one in person like that.

    garden fence

    Since welding started with the smelting and working of iron you will need to look into wooden fences and gates to be predating welding. Mortise and tenon, riveting, twisting, collaring, heat shrinking, lots of ways of fastening stuff together without welding it. However the COSIRA books (available in pdf form free online) covers a lot of this. In particular may I commend to your attention: "Decorative Ironwork" which has 7 designs for grillwork/gates with step by step instructions on how to make them. Note that since we don't know which of the 100+ countries that participate on this World Wide Web forum you are in we can't advise you on design restrictions to meat local building codes.

    Mud quenching?

    Good to know that science hasn't advanced any and so generations of folk beliefs trump x-ray diffraction; metallographic microscopy; etc. I hope he finds a good Doc that can treat his humours with leeches and a cautery and none of this new fangled germ theory of medicine! The recent outbreaks of measles and mumps would seem to indicate he might be able to... I would like to point out that Africa is also known for making mild steel blades---not because they are better; but because that is what they have. The UN Manuals on Blacksmithing include a method of crayoning on hot cast iron to steel the surface of mild steel axes because popularity is the best indicator of best practices! I'm afraid that I will continue to use a high tech insulin pump pushing genetically engineered insulin into me as I Like my life eclectic!

    Moreland and Son Ironworks - Beginner's Log

    Well there are the ASM Handbooks; last I checked they were 36 volumes at about US$300 a volume. Perhaps you could refine your request a bit? Can you suggest a book that describes all cars ever made? I myself only have a few of the older volumes like one on Heat Treating of steel alloys. Most good knifesmithing books will list the most common alloys for knifemaking and giving their properties and working requirements. For general blacksmithing a knowledge of mild, medium high carbon steels will suffice, for historical work pre 1850's: wrought iron, blister steel, shear steel and crucible steel.... TL;DR == No!

    Moreland and Son Ironworks - Beginner's Log

    Me I'd use it straight and gradually work in the wood ash and let ambient moisture help.

    Mud quenching?

    The Farce is strong in that one! Just another variation on interrupted quenches or single step harden/tempering. Unfortunately for most items it's a much poorer method---especially for knives! I'm more of a fan of differential tempering and sometime differential hardening---or both. I was amused by their implication that they were NOT putting in cold shuts, crud, decarb, etc and so on doing their welding and folding as compared to a nice clean industrial process.

    Moreland and Son Ironworks - Beginner's Log

    Cheap clay kitty litter, the really cheap stuff, no fancy additives; just clay. And sorry but the JABOD predates Charles by several centuries! Note that scale will burn right through the tops of your son't sneakers---get boots or make leather spats! Burns on the top of the foot are unpleasant---so I've been told....a friend of a friend, urban legend----stop looking at those sneakers in my trash can!!!!

    Hello from Arizona

    I know a smith in Apache Junction AZ; though I haven't talked with her for several years. She had a lovely IronKiss powerhammer. A LH org I was a member of used to have a weeklong event out near her shop and I'd stop by to howdy.
