  1. I did a bit of experimenting in trying to make a pintle. I wanted to see if I could take 1/4 x 1 flat stock and use that to make a 1 piece pintle for a strap hinge. I left the stock long so I wouldn't have to use tongs. I made a fuller using the edge of the anvil a few inches in from the end of the stock. I then went to work reducing the stock to square from the fuller notch to the end. In form, it work out fairly well but the top and bottom edges if the stock seem to thicken more than the sides. The problem is that going to octagon then round left recessed cold shuts legnthwise in the stock. Is there a way to avoid this? Also, I would like to make a 90 degree bend and then have a shoulder from the pin. While I was able to form the 90, I can't get it sharp and didn't manage to come up with a good way to make a shoulder to have a smooth bearing surface for the bottom of the barrel of the strap to pivot on.

    Any input would be greatly appreciated.

    BTW, I was moderately successful. I did forge it down to ~3/8" round to fit the barrel of the strap I made.

    Thanks.

  2. Easy lube options:

    charcoal, even briquettes that are pulverized are good for this!

    Salt lube take a 1pint container, add 2 tablespoon dish soap, hot water, and table salt to saturate the water (about 1/2 cup), dip your tools and let dry. Makes 1 pint. (thanks for the recipe Mr.Hofi) They dry quick in dragon breath and after the tool is warm from use. Caution this solution can act like superquench and cause good steel to crack if the metal is too hot.

    Those are what I have used with good success.

    Phil, thanks. Will try that. Any idea if I can should quench this punch or not? With the limited punching that I've done so far I've just let it air cool.
  3. Okay, here's a feeble attempt to make a 1/4" punch. It started life as a larger flat bottom punch. I shaped it on the grinder giving it a slight point, trying to copy Brian's. I tried to make a straight shaft and then have it taper after a bit. I tried it out and encountered some trouble. I was punching thin stock and it really didn't work out that well. Guess I need a bolster. Tried it with some thicker stock (1/4" I think) and it worked better but I could get the plug to drop out. It just kind of hung on. I poked it an pulled it off with pliers.

    I have questions about this:

    1) Does the shape of the punch make sense? It's not the best grind but it's my first attempt.

    2) Can I quench this punch? I don't know what kind of steel it is, obviously tool steel of some kind. You can see in the pick that there was some color running from using the punch

    3) What can I use for lube? I use a gas forge so don't have coal dust. Can I used regular copper anti seize compound?

    I think that's it for now. Make think of some more.

    Thanks.

    Eric

  4. Hi, All. Received my new Brent Bailey hammer today. It's in what I believe he calls the Modified style. Fit and finish is fantastic. Can't wait to try it out. Brent was great to deal with. He took a lot of time discussing the hammer with me and blacksmithing in general. He sent me a center punch with the hammer for no extra cost. For those of you that recommended Brent, I heartily thank you and can add my sincere recommendations to yours. Here are a couple of pics. Oh yeah, that hammer is ~2 1/4 lbs. I'm not sure of the exact weight. With the handle it comes in at about 2 lb 10 oz. Off to the smithy to try it out shortly. Thanks Brent!

  5. Those are for flat bar and are limited to the width (not thickness) of stock you are working. So if you get a 2" pair, you can work from 2 x 1/8 the way up to 2 x 1/2. Square stock won't go at all. The ones with the smaller reigns are indeed "springier", and are great.



    Thanks for your reply Nuge. In rereading the description on the site I realized that I misread it originally. It's up to 1/2" thick and I read that as 1 1/2"! Sigh.

    That said, how much flexibility is there in the range of width? Can the 2" tongs handle 1 1/2", etc? I was thinking of getting the 1" and 2" to hand a range of stock. In your experience how would that be? Thanks.
  6. Hi, Grant. I am considering picking up some duck bill style tongs for flat stock. On the Blacksmiths Depot sight it says that they can handle up to 1 1/2" thickness, and depending on the size tong, up to 3" wide. Does that mean it would also work for larger square stock? Would a 1" tong handle 1" square?

    Also, what's the range that the tongs can comfortably handle? For example, can that 1" handle 3/4 and 1 1/4?

    Lastly, 16" vs 18". I would guess that the 16"s are lighter and springier?

    Thanks.

  7. Fciron thank you for your explenation and suport
    when Frank Turley said before asking me how I control and maintain the length of the point my my full answer was ''some knoledge in geometry and experience''
    the squar steel is having 21.5 % more matirial then the round in the same dimention . means that if you round a piece of squar steel it will be longer 21.5 % 1/5 but while rounding the steel after forging squar it swels a bit there for practicaly we calculat 13-15 % longer in this operation.
    In every rond steel a cone is hiding and in the squar steel a piramid is hiding .The proportion in both of them between the full matirial and the cone and the piramid is 1 to 3 that means that if one leavs a ''blob'' of 1''
    and start the forging from the behind towerds the point or with the hammer tilted or put the blob on the far end of the anvil you will always get a 3'' point !!!
    The beuty is that geometry is working in All diameters the same 1-3 many people thinks that if the steel is thicker you need a smaller blob to start with and this is wrong.
    and why did I start with the proportion between the round and sqar ?
    if you forge the point on a round steel there is 20 % less matirial and you forge squar piont you will get the point shorter but when you will forge to octagon and round you will get it to the right designed length.
    If one is forging a point from squar steel then one will have to start the blob a bit sorter 15% to get to the intendent length
    After having this geometry knoledge one needs some experience to master it.
    the longest point I forged in one heat was 10'' IN 5/16 AND 3/8 with my trick system

    Hope I made it clear enough

    Hofi


    Geometry is good! Thanks Hofi for that in depth answer.
  8. Thanks for the guidance, folks. Can we talk about pintles? If I want to make a pintle that bolts on, what is a good way to go about it? Can I make a small strap and form an eye around the pin but make it tight to hold the pin? Is there another way to get the pin to stay in the eye of the pintle? Or do I somehow forge the pin from the same piece as the strap (pintle)? Would it make sense to use 1" flat stock and draw down the end the end to 3/8" round to form the pin, bend it vertical?

    Just some thoughts. For now, simple is good. Any ideas, thoughts suggestions?


  9. 7810d196.jpg

    Details: 1/4 inch square stock. Forged short "spike" on one end. Then set down shoulder on spike with monkey tool. Drew out and scrolled other end. Spike end bent 180 degrees. Pan forged from copper disk cut from water pipe. Drilled under-size hole through pan and forced it down over spike with monkey tool. Use "votive" size candle. After two hours jar was only slightly warm not hot. Seems to get plenty of air to burn.

    Recently added 10 x 30 porch to my house. My wife asked me to forge three candle holders for the porch. This is what I came up with. Two more to go. May do a leaf for the handle of one May omit the spike from the other two and just rivet the pan on. This is because the votives have a metal base attached to the wick which must be removed in order to use the spike. Hope this clarifies. Sorry to be so long. Bart


    Bart, Many thanks for the details! My wife and I both love it and will try to make one. We appreciate you sharing the idea. Great design!~Eric

  10. Nice clean dimple? I'm not clear on what you're asking.Frosty the Lucky.

    Hi, Frosty. As Brian shows in this post


    Rotate the bar/rod after each blow, getting deeper as you form a groove around the periphery, then break off the last bit, that will give what you describe on a round or square barIf you angle the workpiece, you can also control the angle produced on the bar end, from square to the angle of the hardie.

    John, Thanks. I think that's what I'm looking for


    For hot cutting, you need a much more acute angled edge or you will deform the bar while trying to force a cold hardy through.


    Sam, I think I'm following you. If the cutting tool has to steep an edge, as with a cold cut, the bar will deform. Would you ever use that type of cutting to form almost an upset at the end as you're cutting? I realize though that cutting hot metal with a "cold" tool could mess with the temper.

  11. Have any of them complained?


    I'm not trying to start a row, and certainly no one has complained in this thread. I'm simply suggesting that sometimes what seems harmless from one person's perspective isn't from another. It's merely a suggestion, but it comes from personal experience. Many times on forums things are said without due consideration to all that will "hear" them. While I don't think any of the comments here were made with intentional disrespect I don't think they are particularly considerate of our female members. They may never read them and may never complain if they do but that doesn't mean that we shouldn't consider them when we post. Just my point of view. Take it for what it's worth.

  12. ofafeather,

    Here are some older discussions on punches and design.





    There is a few to start you. Do a search on punches and you will find more.


    Brian, Thanks for the links. I just read through the 8 pages of the first thread you linked to. Fantastic! Thanks. I'll read the others later.~Eric
  13. Brian, just want to say THANKS! I find your work very inspiring and appreciate the chance to see it through your videos. Also, your in depth explanations and patience with questions really go a long way in helping this newbie understand the craft better. Thank you! If I were closer I would love to take a workshop with you.
