May 28, 201313 yr Forged holes have something about them that I like. Here are 24 of them : They are nice with the material giving the item something like hips instead of vanishing away. There is elegance in them. They are a signature, a way of saying that a blacksmith made this, they are a statement These are for hinges that will not realy be seen by anyone and if seen, probably unnoticed. But I know.
May 28, 201313 yr Greetings Yves, Like in all quality blacksmithing ( ITS WHAT MOST PEOPLE DONT SEE THAT MAKES THE DIFFERENCE ) Forge on Jim
May 28, 201313 yr I did my first drifted hole the other day thanks to the miss. forge council. They sent me the drift punch. Mine didn't turn out as nice as yours though. All I had was the pritchel hole and it made it kind of sloppy looking. Yours are beautiful! Oddtodd out
May 28, 201313 yr Machinists like to say that they can make anything. Ask them to make a 3/4" hole in 3/4" bar. Blacksmiths can do that.
May 29, 201313 yr Yes and in 3/4" bars, forged holes are just spectacular. In 3" / 4" bars they are awesome!
May 29, 201313 yr Greetings again Yves, I once made a complete railing to the second floor of an observatory with 5/8 round bar stock with 3/4 punched and drifted holes for insetting 3/4 bronze balls to look like planets leading up to a header with a bronze sphere. Yep I was punch drunk Jim

I'm a part-time machinist too, I like this statement! :D I'll have to make a sign for the machine shop- "I'm so good, I can make a 3/4" hole in a 3/4" bar!" ....that outta win me a few beer bets!!

Yep I was punch drunk Jim I want to see this and others with me I'm sure.
May 29, 201313 yr Greetings Yves, I'll see what I can dig up . Might still have one left.... I'ts not all that hard... Jim
May 29, 201313 yr Greetings Yves, I'll see what I can dig up . Might still have one left.... I'ts not all that hard... Jim I believe they may have meant pics of the railing... That's what I would love to see.

May 29, 201313 yr Author Well yeah, ... but then it's no longer a 3/4" bar ..... . Yeds it is! But like I said, with hips.
May 30, 201313 yr Greetings Yves...last, This is the best I can do at this time... It has been 12 years and the bad news is my old laptop hard drive crashed and took most of my digital portfolio with it.. I will still try to find a hard copy but we just moved to our north house after closing my shop and selling our downstate house.. Lots of stuff still in boxes.. Jim
May 30, 201313 yr North house, Downstate house? You have UPer ambitions Jim? Nice job on the bar. Did you slit, upset and drift? Frosty The Lucky.
May 30, 201313 yr Frosty. Yep a lot of slit and drift... Had a bunch of spindles in that job... One key to forming a 3/4 hole in a 5/8 round bar was to form the hole on 2 ball peen hammers to achieve he roundness... The one sitting on my little anvil was a reject... Your right its a 500 pound Trenton on the original cast stand.. Belt line weld with a tool steel top... I thought you would ask... Have a delightful day my frigid friend. Jim

You haven't even asked me out on a date! <grin> It's 83f. right now, last week this time the last and really late season snow storm was just about melted off. So, once you've slit and drifted the hole, you us ball peins as top and bottom tools to form the hole. Doesn't that leave a pretty wasp wasted hole? I'd think it'd take a final drive with a ball pein over a bolster. The final form would be established after the spindle was inserted with a top/bottom swage. I know the tool has a name but it escapes me right now. How do you figure the allowance to slit so the hole fits snugly? I've tried using the circumference divided by two but wasn't too happy with the result. Frosty The Lucky.
June 1, 201313 yr Greetings Frosty, Your question.... I use Whittkers chart of 40 45 percent... Butttt a lot of SWAG... The drift after slitting is a staged so the metal moves slow. I upset it as I am going... Forge on Jim
June 1, 201313 yr Thanks Jim. I don't do it very often and have had fair luck taking it a little at a time. I was hoping for the magic bullet number but know better than to expect one. A boy can always hope though. <grin> Frosty The Lucky.
June 5, 201313 yr Here recently I was dreaming up a project that I would need to put one ½in bar through another but I wasn't sure were to start... would anyone be willing to lay out the steps or even a starting point to doing this?
