@Clickspring I repair, and customize brass musical instruments. I only use silver bearing solder, and I use a 50/50 mix of muriatic acid and glycerin as flux. It's a more aggressive, but much more effective flux overall than the zinc chloride stuff. My solders need to look good, and be air right, part of why I stay away from lead based solder (that grey oxidization looks really bad against silver plated horns), and the silver bearing stuff is measurably stronger. It takes a couple hundred more degrees (fahrenheit) to melt, but it's manageable. I also use that same model Blazer for about 75-85% of my work, so it will do just fine. Anyway, I love your work and your channel, and just thought I'd share a bit. Thanks much!
Man so cool. I love how the ancient design is actually really functional. And of course the perfect touch of beauty. The artisans back then really knew what was up. Amazing work as always
Will add that changing the vacuum pump oil is also very important to getting long pump life. If the oil gets the slightest bit cloudy or murky change it out. No need to go for expensive vacuum pump oil here, ordinary automotive oil works well as well, normally a straight SAE30 oil is the original, but you can use almost anything from a 5W15 to a 20W50 oil in it, and it will do the job. Also a good idea is to also include in the vacuum line a filter, simplest is to get a automotive fuel filter, and place in line with the hose, which keeps a lot of fine particulates out of the pump itself, and the filters are very cheap to buy and replace.
The automotive filter is a great idea! Thanks. Use a straight oil, modern EP additives eat bronze and white metals as in bearings etc... Also important for vintage machines and vehicles. For real high vacuum I believe You need the special oils, but that is of no consequence for applikations like this.
Oh, these lamps had wicks? I always wondered how they would work open like that - just burning oil. They are never shown with a wick... or, at least - I've never seen a picture of one. Now it all makes perfect sense to me. THANK YOU!
Imagine getting so good at casting that you could do casting trees of these in a single pour. Then you have cleanup by files and stones, which is labor intensive, but labor was cheap then. Still amazing casting skill to make them at scale like that.
I did some searching online, and while everything I found was about bronze statues rather than lamps, the Greeks did use indirect lost wax casting to make bronze statues. Lost wax casting itself seems to be a prehistoric invention, which I was surprised to learn.
I think its really cool that the legendary Charles Frodsham & Company are one of your special Patrons, perhaps you could make a double anchor escapement, as I'm sure many viewers like myself would love to see that, or perhaps your own implementation of it. Love your work as always!
It's truly amazing to see a reproduction of something I can see in a museum with the same fidelity a craftsman put into his product centuries ago. You can find all sorts of brass trinkets but none of them have a real craftsman's touch or care because they're production pieces for a mass market. I think the reproduction and seeing what it took to make it really brings home how hard it was to produce those museum pieces when they were new so long ago.
I was thinking the same thing. Chris always makes it look easy, until he say things like "I have been using this for a year." Then you realize how much effort he has put into the background for a 13min vid.
What really amazes me is that these casting processes are STILL the way casting is done. Sand casting is the most common, but I've heard of this type of process being used in major manufacturing currently... The 'amazing' part to me is all that work, into a one-use mold... :D
I watch your channel as a source of inspiration. whenever I think that I have already done my job well enough, I watch your video and understand that I am still far from ideal. Thank you
Great job. What a wonderful handiwork. Thank you for the video!:) Trivia: It's good that we have cars, nowadays. As they took over the "role" (Satire!) of the ancient oil-lamp. She (and the ancient model presented here is even worse as industrial revolution ones!) is responsible for many horrible and painful deaths throughout history.

Merci beaucoup, il y longtemps que j'essaie de comprendre le fonctionnement de la coulée à vide. Je suivrai les prochains épisodes avec attention. Merci
Hi. one of the things that you may be interested in is, where I used to work the shop used a small tank to store the vacuum from the pump with a couple isolation valves that way the negative pressure could be quickly added and relieved and protected the pump from unwanted contamination. I thought the design was ingenious. Rich
Since you already have a vacuum chamber, you could avoid the resin expansion problem by adding another couple of steps. Divide the digital model up into different, easy to mold and cast shapes that have keys on them to help align the pieces. Print and clean as per normal. Make a mold of the pieces from a silicone that can handle the temperature of melted wax. Cast the pieces in wax. Assemble them and clean up the part. Then proceed as normal. While it takes more time, you now have molds that you can use to make a few more copies if you wish and masters to make more molds with. If you're careful with the silicone molds, you could get at least a half-dozen castings out of them.
That is very clever, I was just thinking that 3D printing resin is really expensive and the printing is pretty time consuming so I was wondering if there was possibility to make new positives by molding the original that you get off the printer. But I thought surely if it was castable in a non-destructive fashion. He just have done that from the start, didn't think about flexible silicone molds for making wax copies.
You could also just cast the wax portions separately so cleanup is easier, and solder them all together after. Although the benefits of this are mostly if you have a modular design with shared parts, like reusing the boat and top piece, and having multiple handle decorations.
I would just print the mold that you can fill with wax. Modern resins can handle more heat than paraffin wax would produce. Or you could also print the mold using fdm and a different material as well if you really were nervous about temps.
Its crazy that guys were making this so far before powertools and powered heat. They must have been truly incredible craftsmen with a lot of patience and intelligence.
Brilliant video.... its been years since I delved into casting and its great to see the changes technology has made. As a former archaeology student the results please me greatly as well :-)
Great Video Chris - Got a little lost in the process there between the vacuum chamber and you pouring in the Brass - but worked it out in the end. Might have needed something to show the 3D Model being put in the resin...
Agree. I got totally lost. I watched the video 5 times and still have no idea what’s going on. For example, where’s the pattern?? The end result seemed to come out of nowhere. I’m a longtime subscriber Chris, and your videos are usually masterpieces. But this one, I don’t know.
Superb work resulting in an amazing piece! Well done! While you were scrubbing and rubbing the lamp, I was expecting to see a genie come out of it at any moment :-)
That's a beautiful piece Chris. Investment casting is something I've been wanting to try for a while but it's quite equipment heavy. I did try centrifugal casting at college though. It's super scary!
I too have a thing about investment casting, I had seen a very good TV program about the Bennin bronzes, I then got a question about investment casting in my metallurgy finals. Bingo, a question I could answer easily! I passed.
Great video, thanks! I use a vacuum pump and chamber to de-gas silicone rubber and urethane resin. I'm happy with mine from BACOENG, although I wish that the pump was slightly more powerful.
When I was taught lost wax in school, we had a spring powered centrifuge in the floor that we used to push the metal into the mold. I always forget most people don't.
For real I've wanted to investment cast but never thought I could afford a machine but I also never thought to use the vacuum chamber like this it's really out of the box thinking.
How did the Romans mass produce the wax casting? also how did they cast something with such thin walls without a vacuum source? Impressive they did so much
Maybe they made an original and then a mold of it, used to fill it with wax each time. Take account of how cheap was manual labor back then, specially during some timeframes of the whole Roman history
They did a lot of wax slush molded in gelatine molds. Gelatine molds (think ballistic gelatine, not jello) were stored in springhouses between uses to keep them away from temperature extremes.
Interesting to see a vacuum casting using direct vacuum. I've only ever seen a gated setup with a vacuum tank pre-charged for the casting. What do you think the major benefits/differences to this are? Less cooling of mold during the pre-pour perhaps?
Waw. All teh internets are belong to you. I've watched so many videos on failed castings - for the reasons you described - seeing it actually working is an amazing thing. Very cool. I watch BigStackD, who is in Australia, a lot - and he's going through this right now.
🎉 an amazing video as always one day I hope that I will have the space and time to be able to learn how to do the things that you do and be able to make my own stuff and gadgets
@@ethanspaziani1070 you could get a utility trailer, and bolt it down securely...that's what i thought about doing (i live in a tiny house, but decided to take classes at community college instead).
If you're going to make multiple of the same part or really can't have any cracking. Making a negative mold that you can pour casting wax into from the model works pretty well. You could also print out a negative mold if you so desired as well. It is extra steps and work, so whether that's worth it is kind of up to you.
Man as much as i love the final product, it's the whole process of making it the thing i love the most. It's the journey, not the destination, i guess.
Extra virgin olive oil cold pressed (should be a redundancy) shows a leven of commitment and quality hard to match. Literally it is a top culinary product what you are using for burning. Well, it matches the quality of that lamp :)

Watching molten solder wet a joint is so satisfying.
Watching paint dry just doesn’t do it now!

very cool process, you can really appreciate the initial surface finish when compared to the rough finish of traditional sand casting.
Excellent.
