swedefiddle Posted February 5, 2022 Share Posted February 5, 2022 Good Morning, When trying to learn 'Fire Welding', you have to ask yourself "How hard should I hit these 2 bowls of Jello?". Put your Forging Hammer down and pick up a hammer half it's size or less. Don't splatter the Jello!! You are trying to persuade these molecules to bond with those molecules, Politely!! Please and Thank You!! It is easier to start with thicker material. 3/16" thick material looses it's heat quite quickly. Neil Quote Link to comment Share on other sites More sharing options...
Chimaera Posted February 5, 2022 Share Posted February 5, 2022 Ok, that makes sense. I have done a bit of forge welding, but not much. I think I’ll just try the 3/16 stock I have, and if that doesn’t work then I’ll buy some thicker stuff. I’ll just have to be careful and not let it cool down too much.

JHCC Posted February 5, 2022 Share Posted February 5, 2022 Someone on the forum has mentioned having a chunk of RR track in the corner of their (coal) forge so that they can pull the workpiece from the fire, tap the weld shut, and put it back in the fire for a second heat in about the same time it would take for them to go from the forge to their regular anvil. When IFI member Latticino was teaching me how to weld a tomahawk, he handed me a little hammer that felt like it didn’t weigh much more than a pound. He called it “The Magic Welding Hammer”. It worked really well, serving as a haptic reminder to hit gently in a way that a heavier hammer wouldn’t. Quote Link to comment Share on other sites More sharing options...
TWISTEDWILLOW Posted February 5, 2022 Share Posted February 5, 2022 Hey now! that’s a handy idea! With the rail track in the forge,I’ll have to try that, of coarse magic welding hammers are cool too! Lol Quote Link to comment Share on other sites More sharing options...
Chimaera Posted February 5, 2022 Share Posted February 5, 2022 I’ve got a little 1.25# ball peen I will try to use. Unfortunately, my coal forge is homemade and doesn’t have a good spot for my anvil. However, I can just stick the anvil a foot away and pivot. Now I just gotta wait for the weather to clear up Quote Link to comment Share on other sites More sharing options...
Frosty Posted February 5, 2022 Share Posted February 5, 2022 1 hour ago, JHCC said: “The Magic Welding Hammer”. Experienced tools can make a huge difference for folks learning a craft. Deb was "managing" to knit but tinking almost as much. Tink = knit in reverse for those who don't knit) Anyway, my Mother gave Deb probably a couple hundred of her knitting needles. When Mother knitted it sounded like someone pulling a zipper slowly or maybe a Geiger counter. She was a knitting machine and would carry on conversations, watch a ball game, etc. Of course she grew up in a time where you knitted your own socks, mittens, hats, scarfs, etc. or went without. Anyway, Deb's knitting improved a hundred times in days sitting with Mother, chatting, and knitting with old well worn needles. Unfortunately Mother passed before Deb could get even with home processed and spun yarn. Experienced tools make all the difference, I know it takes a while to train new ones. Gentle firm dead blows set welds best for me but I've set fire welds by laying the joint on a brick and hand pressing it with another brick to prove the point. Frosty The Lucky.

Jobtiel1 Posted February 5, 2022 Share Posted February 5, 2022 A good tip I picked up on some older threads here when I was looking for some help with welding a bit of leaf spring to mild is to kind of tap your hammer in way that you fight the rebound a bit. Firm hits and not sharp hits. It worked really well, even with a heavier hammer. Next time I'll try some smaller ones too and compare how well it welds. I've gotten good at getting a welding fire so that is at least one of the hurdles gone. ~Jobtiel Quote Link to comment Share on other sites More sharing options...
BillyBones Posted February 5, 2022 Share Posted February 5, 2022 Chimaera, I have got 12*F on my thermometer right now. That means that my anvil is also 12*F. You may want to heat the anvil a bit before trying the weld too. I keep a 15# cube of 4140 next to my anvil stand. I can use it for upsetting long bars or pick it up and set next to my fire for quick welds. Very handy to have just a lump of steel around when needed. I use the same ~3# hammer for just about everything and that includes welding. I see it as a matter of hammer control, but that is just my opinion.

I saw one quote that has been removed. Sorry, I was having trouble uploading pictures from my cheap phone. I don't post much, mostly work.

Also far too cold for me to do anything right now :). I will wait till it’s warmer before I do anything Quote Link to comment Share on other sites More sharing options...

I remember he said "the iron wants to weld". Turns out he was right, if you let it happen, it will. Not magic, clean, heat, tap. If you have a large surface area then some flux helps, but I think people generally drown the work in it. I try not to let the iron hit the anvil yil Im ready to hit it. Another hint, if you want to weld with coal you must learn to run a clean fire; that is tje most important I think. Oh, and practice, practice, and practice some more.

ThomasPowers Posted February 5, 2022 Share Posted February 5, 2022 So far today I've drilled 128 holes in L brackets for my Wife's raised bed, (actually 64 holes but I step drilled them). Had to stop and go inside to warm up a couple of times. I didn't bother going to the scrapyard today, all the "good stuff" is on the north side and so still snow covered. Next Saturday is supposed to be in the 60's degF and sounds like a much better time to peruse the scrap piles! My goal is to have my wife's raised beds ready by the time the weather gets better for shop work. I do have to say that having an electric drill sure helps for drilling a lot of holes in steel. Now when I get the drill press back on line I can stack them and drill a bunch at a time. Quote Link to comment Share on other sites More sharing options...

bluerooster Posted February 5, 2022 Share Posted February 5, 2022 Too cold and windy to fool around at the forge. So, I set about the task of fabricating a larger gas tank for the air compressor at work. The existing tank may hold a litre if you're lucky. I had a "mini keg" in the shop holds 1.32 gallons. So I got the idea to make a gas tank of it. and fabricate a bracket of aluminum. I still need to make the straps to hold it in place, and add anti chafe material.

Jobtiel1 Posted February 5, 2022 Share Posted February 5, 2022 You sure that that can withstand the pressures of an air compressor. I would be very reluctant to use anything that is not graded for an air compressor. ~Jobtiel Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted February 5, 2022 Share Posted February 5, 2022 I believe he is making a gas tank for an engine run compressor, not the air storage tank. I would want at least a gas tank that would hold 5 gallon's, I made one for my generator because the factory one only held 1 gallon. Quote Link to comment Share on other sites More sharing options...
bluerooster Posted February 5, 2022 Share Posted February 5, 2022 Yes, Gas tank. Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted February 5, 2022 Share Posted February 5, 2022 That Heineken tank sure looks larger than 1.32 gallons. Maybe 1.32 gallons of beer with a lot of expansion room for the propellant. Quote Link to comment Share on other sites More sharing options...
bluerooster Posted February 6, 2022 Share Posted February 6, 2022 That's what I'm counting on. mabe 1.5-2 gallons? Oh, and one more thing. Ordered new glasses today. Trivex lenses, with IR protection. Came out cheaper than the same thing cost me back in 2006. At the same place. :D Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted February 6, 2022 Share Posted February 6, 2022 I love my Trivex lenses, so much better than the old poly carbonate ones. I'm due for an eye exam on the 17th and if my prescription has changed that's what I'm going with again. Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted February 6, 2022 Share Posted February 6, 2022 Do you have a speaker magnet with a solid core with a threaded hole in the center? I had a friend who was doing circles with a rig like that; but putting a center punched hole in the metal that would propagate as he dished it and so he was making "1 rivet pots". I gave him a small speaker magnet with a solid core with a hole in the center and he moved up to 0 rivet pots! (Easier to clean!) Quote Link to comment Share on other sites More sharing options...
JHCC Posted February 6, 2022 Share Posted February 6, 2022 I’ve got a few things that might work, if the need arises. We shall see. I am thinking of reducing the outer diameter of the ring around the bearing, if the present proves too bulky. Quote Link to comment Share on other sites More sharing options...
Goods Posted February 6, 2022 Share Posted February 6, 2022 Spent some time working on my next knife. Got it forged out and cleaned up a bit. Then started on the guard. No, the guard is not going to be so ridiculously large. It was much large and needs a lot more. Keep it fun, David Quote Link to comment Share on other sites More sharing options...
