ThomasPowers Posted March 11, 2017 Share Posted March 11, 2017 Of course the term "Terminal Velocity" comes into play at some point. Quote Link to comment Share on other sites More sharing options...
beech Posted March 11, 2017 Share Posted March 11, 2017 True, but for a large hunk of steel, terminal velocity is significantly faster that. Quote Link to comment Share on other sites More sharing options...

Farmall Posted March 11, 2017 Share Posted March 11, 2017 Shape plays a role due to air resistance (drag) - Mythbusters demonstrated that a penny dropped the distance of the Empire State Building only achieved a maximum of 64.4 mph. However, dropped in a vacuum, it would go much faster. Skydivers falling with the bodies parallel with the ground are maxed out at around 125 mph or so - but if they go headfirst, they can get up to around 200 mph or so. There are competition skydivers who have reached up to 330 mph wearing the right aerodynamic stuff......the fastest skydiver was that guy that dove from 128,000 feet to break Kittinger's record. Somewhere up in the thin atmosphere, he reached a speed of 833.9 mph, because of little air resistance. He was the first person to break the sound barrier in free fall - they calculated it at Mach 1.24. However, as the free fall continued, as the air got thicker, he slowed down.

Michael Cochran Posted March 11, 2017 Share Posted March 11, 2017 I had over 20 feet of 3/8 round in varying sizes come me home from work yesterday. They used to be part of long rods used to put/adjust tension on gate frames. They burn off the excess when welding them to the gate and throw them to the side until they get around to clearing some of them out. Obviously yesterday was that day. I also found an odd ball and socket joint I found in the scrap bin. I'll cut off the socket part keeping it as intact as I can to see if it has a use I don't know about yet. The ball with be smoothed and polished that again I'm not sure what I might actually need it for. I knew it wasn't scrap so I saved it, that's what's important.

Michael Cochran Posted March 12, 2017 Share Posted March 12, 2017 I scored three pocket knives for $3 because they are 'broken.' The locks work, edges are in decent shape, but the scales are gone. I have handle material already now I just need to figure out how to attach it to an assembled pocket knife. Quote Link to comment Share on other sites More sharing options...
JHCC Posted March 12, 2017 Share Posted March 12, 2017 A successful trip to Costco, with a side trip to the antique/junk shop netting a 10lb sledge head, a Nicholson rasp, and a couple of round files. Quote Link to comment Share on other sites More sharing options...

You're surely gonna need the ball sometimes. I recently have a crave for bigger half spheres for power hammer tooling. I have one as an anvil tool - I don't use it very often, but it's definitely worthy. It was a part of a truck, can't remember the name, Thomas Powers wrote about it several days ago... From yesterday's fair a 3m/10' long 40x10 / ~1,5x3/8" flat stock followed me home. I really hope it's wrought or at least some fine old MS because there is 10-12 more pieces left there. It was something like reinforcing element in the roofing of a very old house. I go and test it ASAP. Bests: Gergely Quote Link to comment Share on other sites More sharing options...

They were the only store showing nut coal in stock in the areas I travel for work. 29 bags of coal followed me home at $2.00 a bag. Regularly $5.99 here. Got some nut and rice. Bags were not great but good enough to get to the 55 gal drum. Spring stuff is in the store here they are closing the heating out. Papy Hope this works better for you than it did for me. The Kimmels coal I got from TSC 2 years ago made a lot of clinker, it would clog up my rivit forge in no time. I still have 200 lb, I may make a side blast forge to use it.

JHCC Posted March 13, 2017 Share Posted March 13, 2017 I like the rice coal more than the nut coal, and am looking forward to trying it in my new side-blast JABOD. Keeping an eye on the local TSC to see if it goes on sale. Quote Link to comment Share on other sites More sharing options...
D.C. Posted March 13, 2017 Share Posted March 13, 2017 Picked these up Saturday. 105# Trenton...137# Mousehole....and a 927 Pexto stake. The stake is headed to an armourer I know. I guess carrying a ball bearing in my pocket is working! Better check that it's not actually an anvil magnet. Quote Link to comment Share on other sites More sharing options...
Hammerfall Posted March 13, 2017 Share Posted March 13, 2017 I needed a walk, so I went to the scrapyard to poke about. I found 190 lbs of 1060 that had the manufacturers tag on one piece. It's 4"X 1/2" and many of the blanks are long enough to get into swordplay. If you've been keeping up with me I just got a 25lb Little Giant. This is the perfect material for me to learn to draw out and grind on. I know this isn't the best steel for knives, but have read it will be good for swords, choppers, and hawks. Anyone have any advice on tempering and quenching 1060? Quote Link to comment Share on other sites More sharing options...
51 Papy Posted March 14, 2017 Share Posted March 14, 2017 Elemental It will produce some clinker. I like it better than the soft southern Kansas coal as it burns a lot longer and full price seems to be about 1/3 the price. Dumb luck, I run a break drum forge. Long story short, decided it was to deep so I built up with a piece of pipe and put dirt in to fill the bottom 1 1/2"between fire brick. Dirt came out but now that's where most of the clinker settles now. It works but you don't weld anything at the end of the day. JHCC Never used any rice coal. Maybe it will light easier ya right. Guess I'm going to find out. TSC ran their heating close out in this area the weekend before I made this deal. Don't wait to long! Good luck!

Frosty Posted March 14, 2017 Share Posted March 14, 2017 1060 makes a fine axe, it won't get so brittle as to shatter if a missed blow hits a rock, etc. It's also good pattern weld billet stock. Nice score! Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Daswulf Posted March 14, 2017 Share Posted March 14, 2017 When you have been sick for over a week and haven't got to play in the shop then you go to the doctors and they load you up on antibiotics and take your blood and give you shots, you need some comfort. I looked at my funds today and finally pulled the trigger on something I've been wanting/ needing for a while. First time I've really felt good in a while! Now I'm excited!

My small welder has paid for itself many times over. It just can't do the big stuff. So now I can start doing the big stuff. It's an investment.

Jim Coke Posted March 14, 2017 Share Posted March 14, 2017 Greetings Das, Congratulations on a wise investment. It will serve you well. If we do not see a lot of post for the next few weeks we will know what you are doing. Buying good equipment does not cost... It pays.. Forge/ weld on and make beautiful things Jim Quote Link to comment Share on other sites More sharing options...
Daswulf Posted March 15, 2017 Share Posted March 15, 2017 Thanks Jim you are correct. It is a Useful tool that will get lots of use. I have a list of some other investments. All in good time. The need of this one won't hold me back any longer. Quote Link to comment Share on other sites More sharing options...
Gergely Posted March 15, 2017 Share Posted March 15, 2017 Congrats Das, well deserved! That really is a beauty, and a good welder is the finest investment a starting/growing metal shop can make. Use it happily Gergely Quote Link to comment Share on other sites More sharing options...
Irondragon Forge ClayWorks Posted March 15, 2017 Share Posted March 15, 2017 Hammerfall, That 1060 looks like grader blade edge blanks. I have a bunch of them and it makes good anvil hardy's. I quench it in oil and temper back to straw color. Quote Link to comment Share on other sites More sharing options...
Marc1 Posted March 15, 2017 Share Posted March 15, 2017 Lovely welder. Reminds me when I bought my first 250A MIG, what a difference it makes to AC transformer welder! One thing I learned is that when it is windy, and the argon get's blown away, you want to use flux cored wire, that far from what I thought it's actually a very good and hot weld. Furthermore if you try thicker core fluxed wire and change the torch bits accordingly you will be able to weld very thick material. Quote Link to comment Share on other sites More sharing options...
