From what i remember, after the wax molds are attached on the main center sprue, the investment material is poured into the entire mold and allowed to dry. When it is dried sufficiently, the entire mold is put into a furnace which melts away the wax inside leaving a negative cavity. The molten metal is then poured into the sprue (down sprue-down gate) which fills the cavity left by the evaporated wax patterns. In centrifugal casting it is advisable to have vents so gasses and excess metal will have an escape route and not leave an air pocket which could cause a small bubble on the finished casting. After the casting cools down, the mold is separated from itself and the investment material is broken or washed away from the castings which are then cut off of the center sprue as well as any vents where metal went up inside of. After that, the castings are rough sanded or wire brushed and all ground parts are smoothed before polishing or sending for plating. A bit abbreviated but one can probably understand the process somewhat!
You can not make a copy from the original the cast copy will always be smaller. The silicon wax and metal all shrink 2 to 3% total combined. But your process is spot on. Apart from the fact you use the original part.
you're right. It's just that you would have to want to go through al this work, and buy the stuff you need, because how it's done is al to see here on youtube, and no skills or talent is needed for this. It's cool alright, because not many people want to go through all this, so he makes a few people happy alright, but at a price, because i'm sure he doesn't give them away for free.
its crazy what hobbies people have. i was just thinking of doing a vw badge as i did a metal cast in HS. funny how this popped up. Seems a lot of work but glad your passionate about it and u seem to it very careful and professionally.
@@rogerd4559 The ring with the wax pattern at 1:12 get investment (high temp plaster) poured into it, let it get hard, and throws it in a oven, burns out all the wax and that your negative.
You didn't show what/how you packed around the wax. In 8th grade metal shop we had some sort of fine black sand and had to pack it around the item. Have no clue how you would pack it around that tree thing you made.
no, investment, similar to plaster but won't burn, and dries water vapour free so you don't get explosions....he also vacuums it to remove air bubbles because those would create voids in the castings and could trap air in the investment and that could cause an explosion as well.... Google "casting investment" and you'll see what it is....
Wow man, thanks for showing this. I make Silver Jewellery and i know of this process but have not seen it. I just make something, whatever comes to mind, out of wax. Then I send it off to a place and 3 days later the Wax thing is Sterling Silver. I usually make rings, trinkets like Charms, Pendants, etc... Whatever inspires me, I grab the wax and begin carving, Then when I have a few items ready to rock & roll, I package them up and send them off to the Metal place and I can have them made from Sterling Silver, Gold, Platinum, Chrome, brass, Copper, zinc, whatever. So I imagine that you are using maybe aluminium of zinc and you have sent these off to be chrome plated. BTW, they turned out awesome, You are a master of your craft. This is NOT by any means easy, It takes a LOT of patience, time, practice, and goofs. So a Smart Man makes 10x just to be safe, even though only 2 are probably required, the original can be "archived" and the replicas can be put on the car. I am interested in knowing why you didn't use the 2 casting nodes on the back of the badge, Maybe this doesn't suit your technique but it's clear how the factory did it. I am subscribing to you man, I love this stuff. Currently experimenting with using 1.75mm wax on a spindle, into a 3D printer. If I can nut this one out, I will be able to create some truly impossible shapes, like a ball in a cube, etc....
Did I miss something? He had wax emblems and then poured metal? Where's the packing sand? Either way, that's some crazy skill buddy. I love watching people being creative and using ingenuity
Wait! Did I miss something? Kind of a waste watching parts one and two. It looks like you poured molten metal onto wax and magically got the end result. I watched because I thought you we going to demonstrate how this was done.
I think he put the wax emblems on the stands, then he put them in a container and filled it with plaster. I could be wrong, but I kind of think that's a simplified version of it.
And so how do you get the final step for emblems (like the "XJS" for Jaguar) that have a mirror-like silver finish on them? I have tried all kinds of "silver" or "metallic" spray paints but still can't get that factory result.
Wow really good to see the time consuming process in copying rare metal work. I initially thought you was going to grind it from a piece of steel or something lol. Well done you have opened my eyes to a really interesting way of doing this.
Around the blue wax piece is packed sand, the blue wax pieces are heated and melted out of the sand making a mould in the sand into which the molten metal is poured.
He uses the lostwax casting (or cire perdue) process, -- en.wikipedia.org/wiki/Lost-wax_casting. Anyways he is very good at his job, is very dificult to get good cuality models ath the end.
I'm very impressed with your casting results! Being new to casting I'm curious about the vacuum on the investment. Does it just help to suck the metal into the mold? I'm assuming the metal cools enough before getting into the vacuum tube and melting it? Without using the vacuum, would the results not be nearly as nice? I'm also curious about the burn out stage of your process. I think you mentioned using a toaster oven in one video? Any tips on how hot and how long to get a good, clean investment? Lastly, do you pre heat your investment prior to your pour? Thanks in advance! I appreciate you showing your results here on TH-cam
+Keven Carter I stopped using the toaster oven long ago, it worked ok for wax, but did not fully burn out the investment like it should for the use of vacuum assist casting. The investment is porous when fully burned out allowing vacuum to be drawn thru it. No molten metal leaves the block of investment (on a good day) The vacuum pulls the molten metal into the mold helping it fill completely which is especially helpful on thin castings and also improves surface finish. Once the investment is fully burned out it should not be allowed to drop below 260C otherwise it may fracture on you. I find using the 260c as a pouring temp gives me the best surface finish when I can get away with it, but really thin castings may require higher depending on the alloy. Shoot me an e mail at aonemarine@aol.com if you need some help with what you want to cast.
This is awesome! How do you avoid air pockets after pouring the metal into that? I feel like the metal would fill it in a way that it could not possible perfectly fill it without imperfections the way the tree appeared to be set up, but clearly yours turned out flawlessly so I was wondering how you managed to avoid air pockets when pouring the metal. Great work, has me thinking of all sorts of new ideas for possible low production methods of creating quality metal creations.
"Who would dare to separate a Marlboro man from his truck", (see 1st part of 1st video for reference). Great work, thanks for showing us how to do a pro job!!
I have the same questions as everyone else --- how the heck did the wax poured into a rubber mold turn into something you could put into a furnace ??? what were the blue emblems made of ?
The waxes are invested into a material similar to plaster of Paris. Then the wax is burned out leaving a hollow cavity that the molten brass is poured into....
Yes this process has a steep learning curve and quite a few pitfalls to get by to do it well but there is much info available (maybe materials less so) on the process. It just takes a little diligence and a high interest to learn it.
hmm, are you saying that the molten metal melted out the blue plastic or how did that work? you went from plastic or wax emblems on a stand to metal emblems on a stand? what level of Magic and Miracles classes do I have to graduate from to be able to perform these kinds of acts?
I found the video of the T-Rex skull and the safe finials, that show the investment pour and burnout process. Very informative. Of all the casting videos that I've seen, I've never seen anybody de-gas with the vacuum chamber at each step like you do. I guess the results justify this. Thank you for sharing.
BEAUTIFUL WORK. There was a lot of detail in the beginning but toward the end I was hoping to actually see the Pour. Actually I was hoping to see this done in Bronze or Brass which will chrome plate better.How did you clean the parts? Bead blasting them. Very high quality work, I would love to know the amount time involved. Thanks for the Video, it was awesome!!!
I'm in elkton MD. Molds (flasks) are at 600 F when the metal is poured into them. If the castings are really thin I'll heat the mold up more, and if the castings are thick the mold temp woul be lowered.
We used that blue stuff in a food machinery plant. It came into contact with the food because someone was too cheap to use the proper material. A few upset customers sent it back to the factory.
Bear with me here. I know nothing about this process, am not familiar with the terminology. (E.g. what does investment mean?) But you lost me after you had completed the tree of blue wax (?) emblems. How did you go from that to the same in metal? Isn't there a step or two missing in between? If you put that tree and pour metal around it, wouldn't you end up with a negative? But somehow you got another positive out of it. I'm confused.
There's a few different ways to do it but if you want the most detail you use plaster. You dip the wax tree in a thinner liquid plaster and build up a few coats. Then you put that into a container of plaster. Once it's dry you put it in a furnace and burn the wax out of it. That leaves a cavity for the molten metal. Once you pour the metal and let it cool you break off the plaster leaving the metal parts.
Schnorschel its a lost wax casting process. Make a duplicate of the item you want from wax. Pack casting sand tightly around the wax leaving whats called an ingate (also made from wax). Its somewhere for the molten metal to enter the form or flask (what you call the contraption holding the wax duplicate and sand). When you pour what I assume in this video is molten aluminum (which is going to be around 1300°F) the wax vaporizes and the metal fills the cavity. Its a pretty cool process. You can also use hard styrofoam (called lost foam casting) and achieve the same results. Foam is a bit tougher to get the same detail as wax but doesnt require as much effort or specialty tools such as the wax injector or vacuum pump/chamber. I cast emblems by making a form of them in casting sand then pouring the molten metal into the cavity left when you remove the emblem. So I dont use wax or foam. Get the same results but this method is better for producing multiple items at once. I can only do one or two at a time. Its a fun hobby and can actually make you some money if you can produce quality products. I started off building a smelter and just melting soda cans and misc. scrap copper and brass to take to the scrapyard. But for the same reason as this video I needed a new emblem for my old subaru and could not find one anywhere. So I watched a few videos to get an idea of what I needed to do to make my own and started practicing. Didnt take long before I could make quality reproductions of the emblem. Posted some pics on facebook in a few subaru groups and next thing you know I had about 100 people that wanted one. Sell em for $50 each so it pays for materials and puts some cash in my pocket. All for a hobby 😁 Watch some vids and if this interests you get into it. Just like anything else it just takes practice. Just be safe man. Molten metal can be dangerous. Good luck!!
I am lost ? How can you poor molten metal around wax impressions with out melting the wax that has to be at least 1200 degrees or more my brain is hurting trying to figure this out I wish you would of gone into more detail
Really good video thank you for sharing. I have to do exactly the same thing, I didnt see anywhere what metal you were using, Im told all the low melt point metals cant be chromed as the acids eat the tin and lead in thinks like pewter and diecast.
I cast them in 360 brass. it was preferred by my local plater as he could just buff and go right to nickel plate then chrome, without having to strike coat and copper coat.
aonemarine brilliant. I was hoping you would say that as my plater prefers brass also. I thought you might have been using Al and i didnt know how to get that plated. Sincere thanks to you for taking the time to make this video
With a home plating kit I've successfully copper struck, nickel and gold plated pewter, although I use lead-free pewter. Commercial plating might be a little different intensity but it can be done. Just saying...
Thank you, I am trying some pewter from melted mugs in the hope it is lead free, I will try plating it. might be easier than having to send out to get cast in brass as I dont have facilities for that temperature of metal.
Clay was used to mould Silicone which was then used to make wax forms which were then applied to a tree and Finecasting sand was packed around them then BRASS was poured no alu, not poured in Clay...
Wish you lived near by, been researching and wanting to do this for years, years I tell you. But I feel like I'm going to screw up my mold making rubber material and it isn't cheap.
That was great.. (i've done a lot of silicon for plastic parts..) but you kinda lost me when all of a sudden you poured metal on it.. please do a voice-over or something like that.. I have looked at the comments and they all seem to say the same... Great video though, and we appreciate you posting it. but you left us hanging (just a little..) Thanks!
Blue Rider I can make them up. When it gets into organic shapes it gets a bit too challenging though. I have another video where i cad modeled it in Alibre and cnc machined the master. Have also done some domed topped enameled badges..

Please do my friend. need to know how to use the vacuum assist cast. I need to cast some fire dept badges urgently. Thank a lot, cheers from the southland where the Spanish language is very fluent.
How come you miss all the steps? I want to know how to do those 40s and 50s style badges and emblems that have what looks like anodised aluminium colors underneath glass
@thehomefoundry Would you be interested in doing some small parts like this for our classic car club? We are the largest forum in the world but there is a small group of us that need a few parts replicated for our speedometers that were made of pot metal causing them to stop working once the original pot metal swelled and broke itself! We are currently working on a 3D printable file but I think casting a new part is the way to go. Let me know if you are interested?
Hello, can you make a custom cast car emblem for me? It's a copy of an original emblem with one number changed. I can provide an original emblem to use as a starting point. If you can, we can discuss privately. Thanks.
From what i remember, after the wax molds are attached on the main center sprue, the investment material is poured into the entire mold and allowed to dry. When it is dried sufficiently, the entire mold is put into a furnace which melts away the wax inside leaving a negative cavity. The molten metal is then poured into the sprue (down sprue-down gate) which fills the cavity left by the evaporated wax patterns. In centrifugal casting it is advisable to have vents so gasses and excess metal will have an escape route and not leave an air pocket which could cause a small bubble on the finished casting. After the casting cools down, the mold is separated from itself and the investment material is broken or washed away from the castings which are then cut off of the center sprue as well as any vents where metal went up inside of. After that, the castings are rough sanded or wire brushed and all ground parts are smoothed before polishing or sending for plating. A bit abbreviated but one can probably understand the process somewhat!
That's what I missed.
But what was the vacuum pump attached to during the pour?
WOW. great videos. a dyeing art of craftment. You are a talented man! lovely to watch your work

Its a fun hobby and can actually make you some money if you can produce quality products. I started off building a smelter and just melting soda cans and misc. scrap copper and brass to take to the scrapyard. But for the same reason as this video I needed a new emblem for my old subaru and could not find one anywhere. So I watched a few videos to get an idea of what I needed to do to make my own and started practicing. Didnt take long before I could make quality reproductions of the emblem. Posted some pics on facebook in a few subaru groups and next thing you know I had about 100 people that wanted one. Sell em for $50 each so it pays for materials and puts some cash in my pocket. All for a hobby 😁
Watch some vids and if this interests you get into it. Just like anything else it just takes practice. Just be safe man. Molten metal can be dangerous. Good luck!!
actually this one is done using plaster. Much finer detail than sand. Also he cast them in brass, not aluminum.
Thanks MASTER THANKS AGAIN
Had a hard time finding
I am lost ? How can you poor molten metal around wax impressions with out melting the wax that has to be at least 1200 degrees or more my brain is hurting trying to figure this out I wish you would of gone into more detail
i need the same thing for my Vespa emblem. 10 would work. could I hire you to make me 10 of them?? about same size as yours.
Really good video thank you for sharing. I have to do exactly the same thing, I didnt see anywhere what metal you were using, Im told all the low melt point metals cant be chromed as the acids eat the tin and lead in thinks like pewter and diecast.
I cast them in 360 brass. it was preferred by my local plater as he could just buff and go right to nickel plate then chrome, without having to strike coat and copper coat.
aonemarine brilliant. I was hoping you would say that as my plater prefers brass also. I thought you might have been using Al and i didnt know how to get that plated. Sincere thanks to you for taking the time to make this video
With a home plating kit I've successfully copper struck, nickel and gold plated pewter, although I use lead-free pewter. Commercial plating might be a little different intensity but it can be done. Just saying...
Thank you, I am trying some pewter from melted mugs in the hope it is lead free, I will try plating it. might be easier than having to send out to get cast in brass as I dont have facilities for that temperature of metal.
I have one also, with the chromatic acid. Its just not something I wish to do for others. Ill just stick with the casting..
Where is the making of the casting molds? That's another 1/3 of the process.
That's pretty Kool nice job but I'm shocked that when you pour hot molten aluminum into the cast why does the clay not melt?Thanks for Video!
Clay was used to mould Silicone which was then used to make wax forms which were then applied to a tree and Finecasting sand was packed around them then BRASS was poured no alu, not poured in Clay...
Wish you lived near by, been researching and wanting to do this for years, years I tell you. But I feel like I'm going to screw up my mold making rubber material and it isn't cheap.
Wooley689 im in Delaware.
Why are you afraid you would screw it up?
Casting a good business to be in?
It takes years to develop
These skills
Keep up the great work

Very interesting
That was great.. (i've done a lot of silicon for plastic parts..) but you kinda lost me when all of a sudden you poured metal on it.. please do a voice-over or something like that.. I have looked at the comments and they all seem to say the same...
Great video though, and we appreciate you posting it. but you left us hanging (just a little..) Thanks!
Dam men you r a genius. Can you make up an emblem or you have to have a 3d object to do it?
Blue Rider
I can make them up. When it gets into organic shapes it gets a bit too challenging though.
I have another video where i cad modeled it in Alibre and cnc machined the master. Have also done some domed topped enameled badges..
Excellent work!! Sorry you do not speak Spanish, you must say very interesting things!
Some time in the future could you do a video on making a plaque.
Supposed to have a plaque being sent to me to cast. But I would think you would want to see one from scratch, as in making the pattern and all???
@@aonemarine I would like to see it from the beginning if possible. Some of the point I would like to see, the draft angle on the lettering, the gates and risers design. Any idea of the material you will be casting, brass or aluminum. Thanks Chuck
@@charlesk8415 there is alot of different ways to go about making a plaque. One of the easiest would be to make up some 2d art in inkscape, then send it to villageimpressions.com to be turned into a rubber stamp.
Why dont you join up on the forum and start a discussion of what you would like to do there. HT1 is a member there with alot of experience in making plaques.

What metal did you use?
360 brass
Was wondering if you could make me an emblem ? I need a batch of them but I want them made in plastic
send me some more information. aonemarine@aol.com
That's amazing man! Was that aluminum?
360 brass
I enjoyed your video. It was not a complete how to video, but I gained enough information to learn something. I have now subscribed to your channel and please don't let the arm chair quarterbacks discourage you, I have yet to see there videos. Please keep up your site.
The same way gold dental crowns are make but this is on a much bigger scale.
Cool
I want 2 of the L-110 series emblems please message me back.
The Ceramic Coating of the Wax Mold seems to have been deliberately missed-out. And yet, this process is well-known, not a Trade Secret. The 'Lost Wax' Process of Investment Casting.
Maybe it was just too boring to put in the video, and its not difficult to figure out.
Seriously what's with the conspiracy theory?
What metal did you use? Thanks in advance
360 yellow brass
@@aonemarine thanks man, it came out looking great, did you use plaster of Paris or investment? Or do you just stick the wax tree directly into the sand? I'm new to this and I really appreciate your help.
@@egyptianamericanpatriot1531 for the investment I use ransome and Randolph ultravest.. its mixed and poured around the trees. Join the forum.

@@aonemarine you are awesome. Thank you for your help and the great videos. You can make extra bucks selling your items online ebay, amazon, etzy, etc.
Now,
About that there them molds there...
What is your contact information, I got some emblems here that need to get done up here. I need to get ahold of you in regards to doing some business with you there
I'm just too busy right now to take on any more work..
@@aonemarine well that's not a very professional reply, I will no longer watch or recommend your videos since your "too busy" for your viewers and potential customers
@@SirVeyXxX personally i would rather have someone tell me that they cant do something than to tell me that they can and then not be able to get it done......
Where the originals made that nice, I thought most emblems were pot metal?
The original ones were pot metal, but alot of chrome plate shops prefer plating to brass because they can skip the cyanide copper strike coat...so I did them in brass...
@@aonemarine They are a heck of a lot nicer in brass, and they will outlast the truck.
Do you work with cast iron?
Do you have a website?
Thanks
hello could you help me create an emblem for my car
Maybe later on this year. Just too busy right now..
Great tutorial but to show the sand/mold stage would be great! Some viewers are a little confused! Are they off a Land Rover 110 series?
Gasgiant they are international emblems. Yes, people have been getting on me about cutting that part out, but all they have to do is watch a couple of my other vids to get the whole picture..
Good job man! :)
the guy just needed two so do you sell the rest
He did..
forgive me if you have already done so, but you should make a video just explaining what all the tools are that you use
ok, ive been thinking about it for some time now. guess i better get off my butt and do it...
Please do my friend. need to know how to use the vacuum assist cast. I need to cast some fire dept badges urgently. Thank a lot, cheers from the southland where the Spanish language is very fluent.
How come you miss all the steps? I want to know how to do those 40s and 50s style badges and emblems that have what looks like anodised aluminium colors underneath glass
Sand molding and Wood box... less investiment ... I think Your way come out two expansive process!!!!!
This is certainly not for the regular Joe!!
@thehomefoundry Would you be interested in doing some small parts like this for our classic car club? We are the largest forum in the world but there is a small group of us that need a few parts replicated for our speedometers that were made of pot metal causing them to stop working once the original pot metal swelled and broke itself! We are currently working on a 3D printable file but I think casting a new part is the way to go. Let me know if you are interested?
You would need to give me a bit more information before I committed myself.
Thehomefoundry@aol.com
thehomefoundry thanks for the reply, I’ll email you some details and pictures in the morning!
A lot of work, but sounds like nowdays, five years later, 3-D copying has made all that a lot of obsolete, unnecessary hard work.
Just commented that on video #1. First thing that came to mind when I saw it.
Hello, can you make a custom cast car emblem for me? It's a copy of an original emblem with one number changed. I can provide an original emblem to use as a starting point. If you can, we can discuss privately. Thanks.
shoot me an e mail and picture. aonemarine at aol dot com
Will do, thank you!
Platers gonna plate
