you know, I talked myself out of seam making tools because of the ends I asked you to show:<)

That's OK. At least it kept you away from that left winger stuff. lol
Just did a quick search for my next object with no luck. I'll do a better search tomorrow. But for now, I'm off to bed to get my nightly South Park fix.

Grats Helen! Yes I do use metal hammers on on such things. The mild steel is the safety net, I promise I am no hack "kid", lol. If its any consolation, you wont find a single chip, bite, ding, dent scar or even scratch on my finishing faces, be it hammer or form  All mirror polished. Carleton |

Congratulations Helen, you're good! I also searched the internet for "old tools" and even searched for similar images with Don's, but with no results. Thank you Don for the contest, interesting one Adrian |

Carleton... could you post some pix of some armor parts (or whole armors) in the member section:)?
Adrian... Don's sneaky! I'll bet he searched for tools BEFORE he posted that, because the normal searches would not have pulled up pix of that thing. It took so long to find because I had to guess USE, BEFORE I knew what to search for.
The giveaway was that the end was flattened and a hammering surface... now what would you need to HAMMER with that type of face? Not wood, not clay, not concrete... METAL. What use in metal would require an evenly spaced slot? A design... or a SEAM. How are metals SEAMED if not welded? They are folded and bent under. What types of metal need to be bent and folded when you can weld? Old metals.... my search actually took me to an entire education in ancient blacksmithing before I moved forward to metal-smithing:).
Last nite, I learned a LOT about the bronze era and how they made weapons, then medieval blacksmithing and sword-smithing, then WHAT application in modern times would require a seam that did not use welding or rivets? That took me to the full range of modern welding applications and techniques, and finally automotive, then I scoured automotive tools and techniques! LOL!
Don came up with a good one, that was one hell of a trip to come to that conclusion!!!

Lloyd, I was with you on seaming tools. My second guess was "forming seams on metal." I didn't use the words setting or sealing, or sheet metal, but that was what I was thinking. No matter...
Don, I hope you can come up with something that is not found on the internet for the next one. I mean, the contest is about knowing/guessing what the object is used for, right? "To prove who is an "old goat" or "old timer."
You could postulate that from now on, there is to be no internet searches. I realize lots of wonderful things can be learned that way, but let's see who knows their stuff, or can figure it out. This is just for fun, right? With that said, I'm looking forward to the next one. Jean

Actually, that tool has very little use on tired old metal which has a tendency to crack and break when bent. It was most often used to join new sheets of light gage metal together. It not only locks the seam together, but also adds rigidity to large, otherwise floppy sheets of metal. It has also been used to assemble the side seams in metal buckets and things of that sort.
I mentioned a blowhorn stake to Carlton. For those not in the know, a blowhorn stake has a very long tapered side, and a shorter more steeply tapered side. Originally it was used to form such things as long, tapered trumpets, and other objects needing a long taper. The shorter side was used for funnels and like objects.

Don... that comment about 'tired old metal which has a tendency to crack and break when bent" brought up a really interesting chain of thought. So I took a quick look about how to resolve that. I mean WHY is Steel considered infinitely recycleable when everyone knows that if you stress it enough over time, it no longer has the tensile strength and bendability of new steel? On the other hand, if you could make old steel as functional as new steel with a simple process, there'd never be a reason to throw out anything steel at all, yet we obviously have to because it eventually gives out. So I looked at WHY, just out of curiosity. Thought you'd be interested too. It's called Metal Fatigue: en.wikipedia.org/wiki/Metal_fatigueBut! If you melt down the steel, and REMOVE THE TIN coating, steel is then recycled and acts like brand new steel again... hrm. Metals are 'infinitely recyclable': greenliving.nationalgeographic.com/many-times-can-something-recycled-2911.html |

Helen, without proper care, steel turns to iron oxide, (rust). At that stage it has become useless. Also, if steel is submitted to repeated bending, it will develop stress fractures. As will most other types of metal. This ends it's useful life. What is meant by infinitely recyclable is that once an object has outlived its usefulness, it can be melted down and reused as new metal. The only real reason to throw out old steal, or any other metal for that matter is if the metal has been allowed to turn into a pile of metal oxides.
Very little tin used these days as a metal coating. It's mostly zinc.
Interesting story about metal fatigue. I once was stationed on a ship where I was tasked with the job of running new air ducting through several compartments. Instead of allowing me to order the propper metal for the job, one of Uncle Sams highly trained and intelligent officers ordered it for me. Trying to cut corners, instead of ordering 24 gage galvanized metal, he found a pallet load of 6061 - T6 aircraft aluminum at a naval airbase. I tried to tell him that it was the wrong material for the job. His response was to restrict me to the ship until the job was done. Sooooo, I played his silly game, and built his ducting and installed it. # months later my time was up on that ship, and I was transferred to a shore station. 2 months after the transfer, the ducting started to self destruct. It seems that T6 aluminum needs to be annealed before bending, and re-heat treated after bending. Every single bend in that ducting developed stress fractures at the time of bending, and within a few short months the whole system fell apart. Now for the fun part. I had been transferred to a shore repair facility, where I was in charge of the sheet metal shop. My old ship came in for repairs and maintenance. Guess who had to submit a repair request to me for replacement of a ducting system ? Yep ! My old friend, the brilliant, Annapolis trained officer. Life does have its sweet moments.

Found out the thing I was going to post for the next contest is too easy to find on the internet. After thinking about it, I'll bet Randy can ID another thing I was going to try. And I can't find another, more difficult thing I wanted to post. Gotta dig through some boxes in the shed for that one.
Stand by. This has been fun. I'll find something.

Well, it's an excuse to sort through stuff, anyway... You might even find something else that you hadn't seen in a while! Jean

Jean, every dig through my shed and basement is a treasure hunt. We moved here 16 years ago, and there are still unopened boxes to go through. Lots of stuff that I'd forgotten I had.

Looks like something slid into the one end, and the opposite (round) end fit into a hole and spun. Used for something heavy.

You're a day late Pat. Helen got it last night.
The answer to your guess is, Nope.

Wow, I feel your pain on the T6, that is the pickiest material I have worked with myself, here is a piece in 6061. (and gets a pic posted for those who requested )   I will grab some pics and do a members post when I get some time. Thanks for the interest! Carleton |

Wasn't any pain Carleton. I made a fool of a know it all officer straight out of Annapolis. It was all worth it.

lol, did he know who he was going to be handing the request to prior? Or did you get to see his face in the moment. I bet it was worth it...  Carleton |

He had no idea when he walked in the shop office. The look on his face was priceless.Of course he tried to play the superior officer game with me, but since I was in charge of the shop, I set the scheduling of jobs. Strange how his work request ended up on the bottom of the pile. We finished the job just hours before his ship was due to leave port.
