Something I wanted to point out, primarily for your safety, is that you need to get some fire bricks to set your high temperature things on. Furnace/forge, crucible when hot, molds when pouring molten metal,etc... should all be done off of cement. Cement is known to explode randomly when you place extremely hot things on it. This includes driveway concrete, and stuff that your garage might be made out of.
Past that, you have a great tutorial set up, that is clear and concise. I'll be trying to follow your steps in making a set of tongs like this.
Glad you found the video useful!
Good points, I had a piece of concrete spall hit my welding mask about 12 years ago when I got my cutting torch a little too close to the concrete. For one reason or another, I haven't seen it happen with molten aluminum on the concrete I pour over, but that certainly doesn't mean it couldn't happen. I'll have to do a little research and testing and make a video about it. It's pretty common to see people pour over concrete, so it is likely a good idea to warn of the lurking danger.
I'll mention that I do place my crucible on a thick steel tube when transitioning between the lifting and pouring tongs. The base of the crucible can be much hotter than the aluminum itself, since it rests on the heating element in the furnace.
Also, the furnace is raised from the concrete by the steel ring base that is on all the 20lb upright propane tanks by DOT mandate. The concrete below does not get nearly hot enough to spall.
Thanks for the input! I'll find ways to make things safer!
I've had that when I've soldered water pipe on concrete in the past. Not something I would do anymore.
Another safety concern is the non-bolted or secured power tools. Great video though!
I have seen people using old disc brakes to sit the crucible on, also I have had heat bricks crack under heat
3:16 your instructions remind me of an old recipe book
These are great! I came here to learn about sand casting. Thanks for failing so that I can...probably a lot fail, too! :)
Nicely made. I would use slightly lighter stock to manage weight reduction. I am an old lady with kitten strength, so a firm but light grip on hot metal is desireable. Maybe 1/8th steel.
1/8" would probably work too. Just be sure to fill a cold crucible with ingots to check if you still have a safe, firm grip!
@@TenTries excellent advice, practical test. If I needed to increase the metal strength, I would put a slight fold in it, lengthwise. Just my opinion, but this is a good design you have
@@picklesnoutpenobscott3165 the fold would probably help a lot! If you couldn't tell, I tried to simplify this design quite a bit
Could these tongs be made from 1/8" thick flat bar instead of 1/4"?
Maybe, your hold on the crucible wouldn't be as secure. For lightly loaded, or smaller crucibles, it might work. I chose 1/4" because I saw how much the 1/8" ones flexed on other videos
@@TenTries Thanks! That's what I was thinking, for smaller crucibles it would probably work but not the larger ones.
Yeah, nothing wrong with trying! I checked these with a cold, weighted crucible to make sure I had full, comfortable control before working with a hot crucible
I think you may be better with a rivet hot forge from 1/2"pin rather than a bolt and nut. My stupid OP.
You're probably right, but that would take skill and I don't have much of that to spare haha
@@TenTries Compare to what you did, that is low level skill
I think the trick would be to get just the right tension after the rivet cools. That might be difficult. You certainly wouldn't ever have to tighten it though
Sorry, but the pouring tongs are WRONG! They require you to use a lot of your strength just to keep them closed against the crucible meaning less strength and therefore less attention to correct pouring The best pouring device is a simple crucible fitting hoop on the end of a suitable stout shaft .The industry standard pouring shank! Much safer and much more controllable. OH ,and you do NOT need clips to hold the crucible in the pouring shank. I have never used such devices and in 60 years plus of pouring metal I have never had a crucible fall out of a shank!.... Martin
Thanks, Martin!
I'll take measurements on the clamping force required because it is surprisingly little for a #4 crucible. I'd say it feels similar to holding a pint of beer. For much larger crucibles, this design would not work
The clip may be my engineering (arguably over engineering) past showing through. There's usefulness to a little extra peace of mind when pouring. It may not be absolutely necessary, but I and many others don't have 60+ years of experience to give us that peace of mind. With this design, I know there's no way for the crucible to slip out as long as the tongs aren't opened any further. I think that peace of mind is well worth the little bit of fab time on the tab.
Are you anywhere near Kansas? If so, I'd invite you by to lift a crucible and have a beer. I think it's hard to explain in text or video how it feels to use these
-Chris
Thanks for the tips, gentlemen.
It seems to me a simple holddown is justified. If a crucible did fall out, for example, during a full tilt as the foundryman pours out excess melt, there would be trouble. Cheap insurance.
Hey... Shanks a lot for the info!👍😉🇨🇦
I made my own from bar stock! They work great! Nice video!
Thanks! Just saw yours. They look great too!
yes, somebody else will have a different approach. have you check luckygen1001 channel? he is a old sand crab still pouring iron almost every week. yes, he is a old guy, which, implies he had done his job for a long time without any accident that can kill him. such as dropping cruisble. that's something we can learn from him. one of his secret weapon is a cruisble cart, just some scrap metal and a pair of wheels to build. but it can reduce some dramatic scene. he is pouring iron and steel of all kind, that's a lot high temperature than aluminum and easily weight 40~50lb per cruisble. he had detail instructions on his channel , not just the cart, but answering casting problem too, worth that 5 mins spent to say hello there and learn something.
Obviously a great project but I don't have an anvil...or a buzz box. Would have to job this out to someone with the right skills.
Yeaahh...what would I do differently?🤔 But my own Tongs since it would cost a lot less than a welder lol.👍😉🇨🇦
I have a no 8 and n0 10 crucubles. I checked price for a 2 man lifter tong and wow they were nearly 500 dollars.
Use a 2nd locknut so first nut won't loosen with use.
How about you going in a big city where you have professionals who sell this stuff than buying on Amazon.
Do you build & sell tongs ? , I'm looking for some pouring tongs for a #8 crucible
How much would you charge to make a set for me i am handicapped and have severe COPD ?
I think the threadlocker was pointless. It breaks down with heat. Cutting the bolt shorter and peening over the edge would have bee a more effective method.
report me as offensive content. I will report your English :D
I want a 2 person tongs for a number 10 or no8 crucible.
Can you melt copper or brass in that furnace as well?
You want "what did you do wrong?" That ungodly hideous noise you dubbed in round 1:30-1:50 and again around 2:30. Why in the name of whatever you might call holy does everybody and his dog seem to think that flavor of absolutely repulsive garbage noise needs to be added anytime there's more than half a second of silence in a video?!?!?!?!?!?!? Is the idea to drive the viewer away? If so, you came REAL close to succeeding with me.
You gotta quiet the voices somehow. It's worth a Try or Ten
Just subscribed 👍🏻 Great video I’ll have to go build a pair as my I’m getting in to pouring metals. I also prospect in AK swing by you can tell me what I need to work on for pouring thanks
Thanks! Looks like you just started melting copper. If you didn't already know, there are some FB groups with a lot of guys who are very helpful!
I haven't been to Alaska for several years, but it was beautiful when I went! Stay warm up there!
Why you use a pipe and cut in half then weld to the tongues?
Thank you for the knowledge, may god bless your family
Do you sell the tong sets? I don't have the equipment and would love a set I use 8-10# crucibles
Not yet, and I'm further from it than I had hoped I would be :/
Another micro change if one chooses. Instead of the locktite, drill & tap ONE side of the tong, then when you tighten down the nut, you're locking it in place.
Two comments: 1) you might make the lifting tongs more in an "X" shape, like an ice tongs. With that design, gravity helps the tongs grip the crucible securely and depends less on the user's uncertain hand strength. 2) Many pouring tongs use a ring welded to a handle to hold the crucible for pouring. Ring tongs need a holddown to keep the crucible in place during the tilt and pour. A simple, safe, and common design welds the ring to the handle at a shallow angle (15 - 20 degrees) permitting the user to view and control the pour from an advance position at the side. An innovation mounts a short telescoping slide over the handle. The slide features a rod welded on top extending towards the ring and bent upwards like a fishing pole at the same angle as the ring. As the user moves the slide down the handle the bent rod extends over and descends on to the hot crucible, gently holding it in place. After the pour, the user retracts the slide and releases the crucible. A refinement uses square thin wall steel tubing for the telescoping handle and slide to prevent rotation and give greater control. Thanks for a good video.
I agree, for the shippable tongs I'm designing, I did increase the 20 degree bends a bit. It didn't seem to be too difficult to lift to me, but things can always be improved!
I looked at the ring design too. This felt a little more intuitive to use, but the ring would be essential for large crucibles for sure
Nice work. The only comment is that the type of pouring tong you made is ok for smaller crucibles, but not recommended for heavier pours, because the bar might bend at the 90 degrees turns. Instead it's better to use a "L" shaped design, with a hollow tube which is much stronger. Check the "myfordboy" channel on RUclips, he uses this type.
Appreciate the video! Enjoying your content from Michigan. If you ever come this way....first beer is on me. 👍
I've never even thought to make my own crucible tongs. They look great!
Thanks! I considered making all the bends without heating the metal. Glad my buddy convinced me otherwise!
I like your tongs. They are a simple heavy duty design.
Muy buen video amigo saludos
¡Gracias! ¡Estoy feliz de que te guste!
Great explanation! I was honestly dreading having to buy tongs because I didn’t feel they would be worth the money. I hadn’t had time to sit and think about how to make them and now I don’t have to. Lol
You are taking a HUGE risk making jokes about being offended! I feel triggered with micro agressions and will be hiding in my safe space (broom closet) for the remainder of the day. So thanks for that.
When I feel safe enough to leave the broom closet I'll be making a few sets of those tongs. Great video even though it was offensive. Particularly helpful including your measurements as you went and kept it short and sweet. Subscribed.
😂 This is the best thing I've read ALL day
do you has video about your furnace? its very interesting
I started the channel right after building it. I was hoping to have a furnace build video this month, but it's probably going to be delayed. It's coming though!
Nice.
Thanks!
I’m totally going to make these tongs, congrats on 1000 subs
Thanks! They work pretty nicely, and I can't wait to show them off more in season 2!
Good stuff; thanks!
I'll have to give these a go.
So, how did it go? Run into any issues?
tell us about your electric furnace and how you made it
The shell is a former propane tank using 0.5" of castable refractory as the liner and rockwool as the insulation in the walls and lid. The insulation in the floor is a mixture of portland cement, vermiculite, and Sodium Silicate. Although, a mixture of vermiculite and castable refractory would have likely been a better choice. The heating element is a simple 6" stovetop coil heating element. It is computer controlled using Python and an Arduino.
I've been debating how to approach the build video since Tries 1-8(ish?) were the inspiration for this channel, and naturally my memory is the only record of those. I may at some point explain the many different designs I tried, but a full on re-creation would be a challenge. The record of the latest version is a series of saved snapchats of the steps, so also not very helpful for making a video.
In the near future, I'll be making a build video of pretty much the same design but propane. That will allow me to melt higher melting temp metals. If I remember, I'll explain the minor design differences between the electric and gas versions.
Nicely done
Thanks, man!
Good video, useful info. Thanks
Glad it was helpful! 😀
Could you do this without any welding?
Possibly, you'd have to countersink 2 or more machine screws in each jaw so that there are no point stresses on the crucible. Befriending a welder and bringing a 6-pack is probably the easiest way
Fantastic Job done on the tools. Very nice shop.
Thanks! I'll let my buddy know you like his shop!
This channel is under rated...
Thanks, I really appreciate it! Better to be underrated than overrated!
Excellent work,
Keep it up
Thank you!
Do you sell your tongs for resale? I would be interested in buying a pair or two.
Just replied to your comment on the TenTries.com project. Once we are done prototyping a shippable design, I'll send you an email! Thanks!
Yeah. I don't have half the equipment required to make those
@@TenTries did you ever get the product down? Would like a pair or two
Excellent vid. Thanks
