What can I say fella. You drop the one and smash it, you fail to hold the other and it drops in the water (yes, very exciting, no doubt there). Nonetheless you laugh it off (maybe not so at the time) and persevere. Mate, you're an icon. I love the way you show the down side to some of your attempts, not just a completely polished performance at the first attempt. Keep on keepin' on my friend. You are an inspiration, and I truly believe you don't realise it. Be safe man. Oh, the finished item? Looked great through my screen.
We all fail from time to time.. you’ll see in a future video what I’m talking about. I think the fire in the plaster is most likely due to not melting out all the wax completely. I’ve had that problem before. Anyways it still came out great 👍🏻
Wow, you've got some really nice stuff there - TO ALL - CHECK OUT THIS CHANNEL - ruclips.net/channel/UCbgMwToNGjwwgn9BRnzAmEQvideos I thought to same about the fire. It's strange though... I burned out to 630 degrees C... oh well, some must have lingered. Thanks for the input.
thanks for sharing those experiments with us and i want to say that there is an other choice for a good casting it is a mixture of plaster and sand good luck .
Hey in the end that came out not too bad. Good save! I was a huge fan of The Equalizer tv show starring Edward Woodward back in the 1980's which nobody seems to realize these movies are based on. Denzel killed it in part 1, I'm going to see the sequel tonight. Hopefully the new movie does well so someone will start re-running the tv series... Anyhow, worldtraveler does great work, I have one of his castings on my wall. But he does his lost wax using ceramic shell molds, not investment molds. You should reach out to Dave from thehomefoundry (formerly known own as aonemarine) channel, he specializes in small investment molds. Often using vac assist casting, which may be the piece of the puzzle you're missing here. Aluminum also is tricky to investment cast from what I've been told. Dave built his own vacuum assist pouring rig on the cheap too, worth a look maybe if you're going to be doing more of this. You've already got the vacuum pump...
Always cool stuff. Check out the 'honey do carpenter'. He makes aircrete which is a pumice like cement that can be used in a forge (he makes a mass rocket heater stove). So you might be able to make one and a video to go along with it. Best of luck!
Oh Geoff 🤦🏻♂️. I’m sorry to say I laughed a little bit when you dropped the damn thing🤭. 3 hours of sanding 🤣. As you know I’m a big fan of failure but you must be a more patient guy then me , even I would’ve started to give up way b4 you. In the end that piece would be a welcome addition to any collection and looks extremely professional. Maybe my mum was right when she would say ‘ If at first you don’t succeed try try again ‘ or maybe she just wanted me to bugger off🤔🤷🏻♂️.
I'll be honest Bigstack, YOU were the inspiration behind this video. I wouldn't normally display so many failures, but I loved the way you pressed on and how refreshingly honest it was. And I thought, he's right! People should know it doesn't always go right... especially if you drop the damn thing : )
I would have been equally ecstatic... if I hadn't had to spend 3 hours sanding it to something half decent : ) They tell me with lost wax casting, what you get out is a perfect copy of what you put in... my efforts have yet to achieve such gratifying results. Thanks for your input ; )
en principio no debería de salir mal la fundición, no se a que temperatura esta el metal, eso es algo importante, yo quizás reduciría el grosor de la pieza un poco, pero en molde de arena o petrobond debe salir perfecto. saludos
Have you tried simply pouring the investment directly to the 3D print, and then burning the plastic, instead of making a silicon mold and then a wax pattern?
Hi Slick. I've never tried Lost PLA Casting as I've yet to see it done well. I'm a perfectionist for my sins and I'm always pushing for better results - though I don't necessarily get them ; ) All the Lost PLA Casting I've seen has looked pretty grainy and as I don't have a 3D printer, it's a bit of a pain for me to lose something I've just spent £20 or whatever to have printed. But in time, I might get around to it.
You're absolutely right. It takes a lot of time and heat. Personally I heat for 1 hour at 80C to allow most of the wax to drain out, which I filter and reuse. Then it's 3 hours at 230C (the initial burnout) Then 3 hours increasing 150C each hour until 730C Then 4 hours at 730C Then hold at casting temperature until the pour, so as you can see, that's a minimum of 11 hours. The only bit I'm not managing yet is the last part... I don't have another kiln : )
Hy sir, I always cast aluminium in plaster and every time it bubbles fiercely and destroy castings I've tried drying the mold as much as possible but no help. Please help
Hi Ibrahim. Good to hear from you. I'm still learning myself so I can't speak with authority, but here's what I've learned and observed so far. It's not just a case of using any old plaster. Casting plasters are specially light and, to a limited extent, porous. Drying plaster alone isn't enough - it has to be cooked at high temperatures for quite a long time - look at this example of a 'burnout' cycle - www.srs-ltd.co.uk/technical/burnout_cycles.html Some people use vacuums to pull out the air as the metal is poured. I rely on venting. You must vent! You need a way for the metal to go in and at the same time a way for the air to go out. If you don't, you'll mix both air and metal - with bubbly results. Finally it seems (and I'm still looking at this) that the plaster needs to be the SAME temperature as the metal when the metal is poured. I'll likely be posting more videos on this subject and I'll try to make all of this nice and clear : )
dengit, I'm not entirely happy with my pun. Can anyone help set this one straight? I find punny humour works well for venting frustrations.... Especially if it's venting frustrations that need to be vented XD
I think casting puns shows you've got metal. I could have got burned showing such poor foundry work, but I like to think I've got a little more sand than that.
I can't stand failure... I'm incredibly tolerant of it in others, but towards myself I can be quite harsh. If I know something is possible but I can't achieve it, it drives me mad : )
Thanks for that Andrzej. I still might not have a go at lost PLA, but the way Myford handles the investment there is very different to convention. Just like him, I have no problem obtaining an investment with beautiful crisp detail... but for me everything after that goes wrong. Clearly he has allowed the investment to fully cool (convention says keep it hot) and then he's surrounded it with Green Sand, much as I do with Lost Foam. I have to say he may well be on to something there. I might give it a go. If it works, obviously I'll give Myford all due credit : )
Hi Andrzej. I took you advice and tried Myfords method today... not for PLA but for Wax. The results were pretty good. I plan to do a video showing this. I'd like to thank you for point this out to me as I always like to give credit where it's due. Would you like me to NAME you in the video, or would you prefer to stay anonymous? It's your choice. Please let me know : )
No worries. I won't make a fuss then... but just know I'm grateful. And Martin is a mountain of knowledge and a very friendly guy. Please subscribe to him. I'd love to see his channel grow ; )
Hate to say this, but I'm more a Tesla man : ) But if Edison said he needed to find 999 ways not to make a light bulb, I've got a lot more bad casting to do... that's easy for me : D
VegOilGuy I grew up in Florida near Edisons winter home. While touring the place, one of the docents let me in on some of the nitty gritty about Edison. I learned real quick what a character this guy was. Sorry, this isn't the place to fill in details.
According to popular culture, none of the famous inventors invented anything. It can't be proven and chances are is sour grapes. I've no gripe with Edison, I just have more hero worship for Telsa. The guy was a genius.

You are a true gentleman, good sir : )
Besides the humor, your tenacity is to be commended!
Thanks John, I appreciate that : )
I'm told some kinds of 3D printers can actually print in wax filament now. Might help a bit in the future
I've heard that too. It's an exciting idea : )
Thanks for that. Please let us know how you get on : )

Thanks for the input.
I am a new subscriber and I am really enjoying all your videos! Thanks for your effort in making them for us to view!
Thanks Randy. This is EXACTLY why I make videos - to ideally help and entertain others, so it's great to get feedback like this : )
What determination, nice work.
Thanks Michael : )

Thanks Nate. I'm always keen to learn new things : )
My favorite part about your channel is you d casting and your voice!
Thanks IbEX... I can't take credit for the voice, it's the only one I've got ; ) But I do enjoy casting... especially if I can get it to work.

VegOilGuy yeah matey not a problem at all I’ve checked it out and it’s great😁👍🏻
I´d be ecstatic with a result like this...

There : ruclips.net/video/HVgPM1ojyLw/видео.html
now you've seen it :P
Keep going
Mix one part sand one part gypsum or plaster and first coat use a brush
Regarding burnout let it burn slowly
Thanks Rabih. I guess patience isn't my thing : )
My understanding is it needs enough time and heat to not just melt and pour out the wax, but to vaporize out the wax in corners that won't drain well.
You're absolutely right. It takes a lot of time and heat.

VegOilGuy thank you sir😀
If small vents aren't your forte then you have to go with huge ones next time. :)
Thanks Pekka. That's the plan : )
"And then dropped the damn thing" 🤣
: D
well, one things for absolutely sure: this video took quite some investment...
$)
dengit, I'm not entirely happy with my pun. Can anyone help set this one straight? I find punny humour works well for venting frustrations.... Especially if it's venting frustrations that need to be vented XD
I think casting puns shows you've got metal.
I could have got burned showing such poor foundry work, but I like to think I've got a little more sand than that.
As long as it's not beach sand, because that's all salty... And I really don't like salty beaches...
Wow, you are really bad at giving up! (and that's not a bad thing 😂)
I can't stand failure...
I'm incredibly tolerant of it in others, but towards myself I can be quite harsh. If I know something is possible but I can't achieve it, it drives me mad : )
Try lost PLA casting like this : ruclips.net/video/HVgPM1ojyLw/видео.html

Anonymous please :P I'm watching a lot of videos from Olfoundryman that you recommended - this guy is pure gold, thanks for sharing.
No worries. I won't make a fuss then... but just know I'm grateful. And Martin is a mountain of knowledge and a very friendly guy. Please subscribe to him. I'd love to see his channel grow ; )
Already did, that's quality right there :)
Wow, talk about persistence. You're like Thomas Edison, think of all the ways not to do lost wax that you don't have to do anymore. ;-)
Hate to say this, but I'm more a Tesla man : )
But if Edison said he needed to find 999 ways not to make a light bulb, I've got a lot more bad casting to do... that's easy for me : D

That sounds like a story worth hearing : )
oh, everything I've read about him is that he was a jerk that stole inventions or brow beat people into giving him their inventions. Kind of a bully
