Making Better Crucible Tongs for Metal Casting: Lifting and Pouring, and 2 sizes of crucibles
HTML-код
- Опубликовано: 26 июн 2021
- FINALLY I made something new for metal casting. Remember those 2 new crucibles I got? Well, i didn't feel like pulling them out of the furnace with my hands, so I built these new tongs. Since i'm lazy, however, I didn't feel like making separate lifting and pouring tongs. I wanted 2. I'm still bitter I needed to make it with moving parts, but i'll get over that soon enough.

These are easy lift and easy pour, thanks to some clever (read: Stolen from others' tongs) design features. Watch and try to guess where a bit of welding slag falls and burns a hole in the top of my shoe. I edited out me jumping, but it's there.

“Don’t do as I do.”
YAY ZINC FUMES IN ENCLOSED SPACES.
I’m glad I’m not the only person who’s done something that spectacularly Darwin-tempting and gotten away with it.
Damn that’s the biggest #8 I’ve ever seen 👀. Dont give yourself metal fume fever welding that galv matey. Great tongs Paul they look crazy but I’m sure they gonna work perfectly! will definitely tune in when you use them👊🏻😁🍻🍻🍻
Weird thing is both of those crucibles are stamped #8. I thing someone is trying to mess with me haha
I'm gonna try them soon, hopefully they handle the weight
I’m so glad you remembered your welding helmet. Sheesh scary.
Yeah I wouldn't want to stare right into a weld, even a tack weld
Paul,
First of all... 🤣 love your fluctuating attitude between quality and functionality. Cobble-ing together a functional crucible handle is definitely not easy. Even when your using an unlimited variety of materials and champion welding skills, it is still a challenge. Your can do, no matter what is lacking, attitude is teetering between MacGyver-ism and oops, did I just do that? Love your on the fly commentary and followup captions. 💪😎👍🤪 🤣
I mean... good stuff.
That's the best video I've seen in ages! Keep it up, if you last that long...
Love how you just wing it and give yourself a hard time about it, very modest aha
It's more fun that way
The only instructual video that makes a simple project look hard hahaha. Thanks.
Most Excellent. Excellently thought out. Works great.
You should get a patent.
Wouldn't know how to do that
I am gonna say this who cares being 1st not me It is good to see Paul's garage upload a new video It's about time✌👍
hopefully a bit more coming, especially picking up on metal casting again
@@PaulsGarage Can't wait I do a little casting myself and i have made a few things myself too My picture the bear is made on a pewter that I made And to me I think you do OK work That's how I would do it The best way you can ✌
I honestly don't either-it was just Bizarre to me. Just glad to see he is loading and seemingly doing well.
@John Moellering same with the Casting. Have some projects. Unfortunately the wife decided she just *had* to have a Pot Bellied Pig-cute in an Ug;y was then it started getting Big, at the remote for my PS4, ate some shoes, ate the walls, crapped everywhere so it got put in the back yard where, guess what? My 600# Anvil and my casting furnace reside so now I can't do anything till I get new fencing up [[which she detroys too]] and move that bigassed anvil and other stuff so we don't end up with Hairy Bacon smoldering out there. :D
Love your projects, but your wordsmithing is the best part.
Thanks!
gotta love a well thought out plan, those are gonna work great
I used an old fire place log lifter, and cut two sections out of it, the front half was a perfect pouring tongs and the back half only took twenty mins of work to make lifters from.
Neat idea! I dont have any of those or I might have used them
@@PaulsGarage yeah it sure saved a lot of work.
Interesting approach! I still need to make lifting and pouring tongs myself. I shall await your test results 😋👍👊
Hopefully it doesn't all fall apart lol
I'm glad I'm not the only one who needs a pair of tongs and is waiting to see how these work out.
Looks great, Paulie. Nice to see the drawing worked out - just enough information to prompt your memory.
Yes the zinc fumes! But the end result looks surprisingly functional! I look forward to seeing it in use.
Lights look great on screen!
Like your base design. With a few bends it was just right. Thanks for sharing.😎⛏⛏🔥🔥
Thanks 👍
Paul must be telepathic or something. I literally just bought stuff to make a better pair of tongs than what I have right now. Actually just watched your old video on this yesterday to get some ideas.
Yeah, watching you shake the crucible really made me think "You're a brave man kemosabe"
can't wait for The Test
Same here
You and I work a lot alike. I have thought my safety glasses were my welding helmet many times and pulled the trigger on the mig gun to find out that the safety glasses do not auto darken... Also weld almost everything on the floor because my welding table is usually full of other tools, etc... I Enjoy your videos!!
"PROPERTY OF US POSTAL SERVICE"
Dr Frankenstein center of mass?
Good video
And you have an auto-darkening welding mask. Imagine what it was like using the old type of welding mask.
I really like your tongs idea.
I was also thinking about having a set that has dual function lifting and pouring.
However, because the crucible needs to be set down and have the slag and or impurities removed from the top of the molten metal, regardless of what type or kind of metal being poured, it appears that it won’t save any time with having a dual operation set of tongs.
Though I still like the idea of having a single set of tongs that functions for both operations. You built what I had always wonder about. Great job!
Nice fabricobble.
I love your shirt!
Thanks! I had to rewatch to see what I was wearing haha
Very clever idea. I wish I had a single set of tongs to lift and pour. I have one set for lifting, then I have to put the crucible on a fire brick and then use a second set for pouring.
I wanted to avoid that. The old tongs I have are basically lifting tongs I use for pouring but that's only manageable with a small crucible. Hopefully these work better
Looks like a very functional design. 👍
Hope it doesn't stick in use.
Same here! I'm mostly worried the big side of the jaws will stick. Crucibles get a bit soft and sticky at high temp, but at least this will only be aluminum temp
I like it! It seems a bit odd pouring with the handles at that angle, but the balance seems good. I like the lip over top too.
The angle is a bit unusual yeah, I hope it works well
If it fits it ships... looks good enough for now
Hopefully it holds up when everything is hot
I read crucible.... I hit like! :) Hi again Paul! ps; how much are commercial tongs? I personally wouldn't trust myself on such a safety thing. :)
Not enough video out there!
I agree! need to pick up the pace
My old fireplace tongs aren't big enough for my new 12kg crucible. Time to make some new ones!
I've seen some pouring tongs with wheels if the crucible gets too big, might be useful if you're trying to control 12kg in a pour
@@PaulsGarage I think the ones in this video are the same size. I'm just using it for aluminum anyways.
paul help debunk the shit about welding galvanized stuff. there is not enough zinc on those parts to do anything to you. yes zinc fumes can be bad, but even if you get zinc fume poisoning, also known as zincfever, its a temporary thing, you feel sick for a day and its gone, no further harm whatsoever. the reason why you dont want to weld galvanized stuff is because the weld turns out shitty, if you can live with that (in case of those tongs, even a shitty weld is still plenty strong enough) you can absolutely weld galvanized steel. having good ventilation should be a given whenever welding anyways, so its much less of a reason.
people are happily melting brass stuff in their garage, where you let off more zinc fumes than you could ever let off by welding parts together
Great idea, but I don't think it can handle the weight with molten metal in the crucible. Maybe aluminum, but I don't think copper. I think it needs to be a thicker gauge metal.
Well, there's your problem... *"The"* Workbench. You need to fill the space with benches before you accidently fill the space with cars/storage/lawn-tools/etc... Then fill the benches with benchtop tools, to take up that space. Look, each tool _has_ to take up space, both during operation and storage. If it's storage location _is_ it's operating location, then all you have to do is clear the area of other tools which have migrated there, not clear the whole surface and move the bigger tool. Even makeshift benches are better than no bench, but benches that stick out should be on wheels.
My shop is a *POD!* Ya know, one of those half sized, rentable storage containers. I have a mill station, lathe station, bandsaw station, welding station, _and_ storage for both shop and household in there, as well as a plywood loft held up by rope where I run my power.
Fix your workspace and you make Making much more fun! I'm not naturally a neat or organized person, but having everything in the Pod has forced me to evolve, so I stole Adam Savage's "First Order Retrievability," and it's working great so far.
Good ideas! The car doesn't have to live in here but the storage garage for it is predictably filled with junk that needs to head to the scrap yard
No giant copper mirrors for focusing gigawatt lasers for you then!
Looks like the ones I made yrs ago.
How much space is required around the crucible for these tongs to work and is there a way to tweak them for a vertical straight up removal from the furnace
My excuse is: When I was little my dad would toss me into the air and catch me. We had very low ceilings in our house.
Your videos are awesome! I just wish I was better at building stuff. These rings are the best ones I’ve seen I thought I could make them but…… Fail. Weird question. How much would you charge to build a set of these? I’m a single dad and didn’t realize how much it was going to cost to actually start melting. I have my crucible. My foundry I built need tongs tho. Lol. Let me know please. Thanks
fill the cruisible up withn wet sand and try if the tongs still hold on , better to find out with wet sand than with glowing hot metal
looks like the spout of the cruisible needs to be pointing slightly away from you when picking it up so its at the bottom when pouring
i actually like the design i think they will work though some of the metal couldve been a bit bigger (guessing when the bottomhalfround bit of the clamp wraps around a red hot cruisible it become slightly malable and might bend open)
you might want to round off the corners of the angle iron where it grabs the bottom of the cruisible so it doesnt leave cauges on the cruisible
Weird. Looks like I am first. Hadn't seen anything from you in a bit. I simplified my "Build" for Tongs. Ordered a set of heavy duty fireplace log tongs, heated them in my forge till I could trist them using large Pliars then quenchd them.
thats a pretty good idea!
@Paul's Garage Has issues with large Crucibles-I think yours is likely better but for smaller things works well.
I'll put my anemic stick welds (pretending to hold my lifting shank together) up against your semi-competent MIG welds any day. I'm confident I'll take first place in the category of Most Embarrassing Weld. :) Also, I think my stick welder is related to your drill press; don't ask how.
I guess you're going to find out how they work.
Explain to me, as i am tired to BURN MONEY buying crucibles.
Why, after following instructions to preheat new crucible, they show lots of cracks that are glowing through ?
Melting aluminum was ok, but when i went higher, cracks started to show up.
I bought 1800C crucible to melt 1400C cast iron. Same issue. One pour and they show cracks.
Who really cares about the looks, if it functions well. If you have to do some tweaking, that’s ok too. Looks to me like they are going to work right.
The only thing I have seen that could be an issue is the pouring angle. With the sloped arms, when you turn them the crucible rotates down and turns toward you at the same time. But that will only matter if you want it coming out the spout… The pouring handle you added should be really helpful.
Good to see you again. Come back to us sooner next time.
If the spout is pointed away from perpendicular about 30 degrees it lines up right when I turn it to pour, but there is probably a 80% chance I'm going to forget that lol
@@PaulsGarage I figured you were quite aware, but I was thinking if I did that, I’d screw it up…
Those are great! I might make a pair for my unproven foundry now that I have a burner! Also, Don't weld galvanized steel indoors! Isn't it CYANIDE gas that is makes? You had your face right in there. No amount of beer will fix that.
Not cyanide gas, it's zinc. It'll make you feel really crappy, but it's not normally life-threatening. The real nasty stuff is using chlorinated brake cleaner to clean metal before welding, the UV can break it down and release phosgene, which can kill you or send you to the hospital if you're lucky. Welding galvanized is best avoided, but if it's really necessary you can grind off the coating before welding. The dust from grinding is larger than the gas released, so a respirator will catch it more easily.

Camera is so much better. Light looks right (apologies to your eyes). Ps; Fan isn't so loud that you can't be heard clearly.
Good to hear!
I think you can fit like 20 pounds of aluminum in one of those crucible‘s I imagine that those are very big crucibles I’ve never seen one that big one just kidding I have it holds 250 pounds of bronze
18:27 is it weird that I'm reminded of "your booty"?
Not weird at all! How's it going?
please don't use galvanized
Yeah I probably shouldn't but that's all I had available and I didn't have time to grind them clean
