Beautiful... The sculpture and the video. Texans probably know cattle brands better than anyone else.
Damn mate that’s 1 hell of a burner set up you got there looks like something off a time travelling jetpack . I tell ya matey you have a lot more patience than me . Absolutely perfect smooth pours 👏🏻👏🏻. That end result was definitely worth it as you know there’s nothin more satisfying than finally finishing and holding the final product so much work went into. Good work my friend, take care and talk soon 👍🏻😁🍻🍻🍻
Thanks brother! All about function.
wow! All I could think of was "master craftsman". Amazing work, truly! Well done
Thanks for stopping by!
Woah.... That's a lot of work mate, what a lovely finish, kudos man. Cheers 🍺🍺🍺👍👍👍
Man, that's awesome!! I was a designer for a big foundry out here in Texas, and had to learn a lot of this myself. So, I feel your pain on the silicone sticking to the rope.
Thanks Ricky! Welcome to the channel! 👍
Way to go Jason, another great set of castings! Nice little peek at the patination process too, thanks.
lol.. Yeah bowling alley wax on fire looks cool. Maybe I'll do a boring video one day and show the full hot patina process. Trust me, it's not that exciting. ;-)
worldtraveler lol, I just realized what you meant there. D'oh! When you applied the wax it looked exactly like every patination video I've ever seen 😀
Very nice. Love seeing someone doing proper investment casting.
Thanks Walt! UA-cam is littered with asshats. I try not to be one of them. :-)
It's also littered with people who think casting is just pouring hot metal in some sand, then they try to pass off their flawed castings as acceptable. It truly is refressing to see good craftsmanship.
Fantastic project and a great video - definitely worth the wait! Thanks for sharing your less successful attempts too, it helps balance the expectations of us ham-fisted amateurs!
Thanks for your patience. I work a very full time job and I don't make a dime off YT. I have more than 100hrs in this project including the video and editing work. Ya do crazy stuff like this for the challenge and the look on the persons face when ya give it to them. That makes all the long hours worth it. ;-) Grab your phone and lets see whatcha working on! Don't forget to check out www.thehomefoundry.com Lots of great folks there of all skill levels. All the best!
Great work and nice video! Patience + craftsmanship is always a good combination.
I dig the way those barb wire rings turned out!!
I pooped out wax with my sculpey extruder and treated it like rope. It's amazing bronze will cast down so small in ceramic shell. Much thinner than that would require solid investment and under vacuum. ;-)
worldtraveler I wonder if the temperature of the mold contributes to that!
The Spidey in me Say's you have skills. Not to mention patience.
Thanks brother. Now please teach me to weld stainless steel. Bronze is easy to me, I must be dorking up pretty bad.
Nice project!
Thanks! I had fun making these and turned them into a couple of great christmas presents for 2 great families. The most valuable thing you can ever give someone is your time. They got a lot of that on this one! lol ;-)
Very nice video friend😊 thank you for sharing
Long time waiting for a new video
I liked the way you explained your failures some people don’t
Keep it up 👍🏻
Thank You! Failures can be the best teacher sometimes. I'm not giving up on directly investing organic materials in ceramic shell. My work has been keeping me busy and it's been 108 degrees outside!!! Thanks for watching!
Thanks for sharing sir
Amazing work!
Thanks brother. Ceramic shell is amazing technology. I tried sand casting, but couldn't make peace with it. I leave that to you experts.
interesting video! Nice process!
Thanks! Keep up the good work yourself! Electroforming has lots of possibilities. I'll show a neat technique soon utilizing it with Dalle De Verre once I nail this glass thing!😎
you are an modern metall conjuroror master really awesome work i experiance around with diff.wax sorts (bee wax and industry way mixes)for getting better results and best silicon when possible(when needed) but i just make mostly single pices no copy needed have good times
Thanks brother. I like one off stuff too. No mold needed, straight to investment. Watch the anchor video for a free style sculpt I made for my niece. Keep up the good work yourself!
very amazing :)
Thanks! When I give a gift, I like it to be a part of me!
Another fine video! Tell us about that cut off wheel you are using in your grinder. Looks interesting.
Barry
Barry Luke Sure Barry. That is a Lenox diamond blade from Blowes. Works good, lasts long time. I only cut bronze with it.
Nice video, cool channel I subbed
Thanks for visiting! Life keeps me really busy, but when I upload, I try hard to make it worth watching. ;-)
No problem buddy
looks great man, looks like alot of work, but it defenitley came out nice. Also, Im kinda supprised that you even needed to start up the furnace to cast that stuff out with the heat you guys have had down there, lol. Just stick it out the back door and wait 15 mins, then pour, lol.
Thanks Chirp! Yeah, I swear the bronze was melting just on the work bench. 108 outside, the ceiling in my garage was 114 and the underside of my roof was 150. Had to keep wax and shell stuff inside the AC.
ouch, yea, far too hot for me, lol. At least you wont have much trouble cleaning the wax back out, just sit it on the mesh filter and come back a few hours later, it'll be done for you, lol. That and dewaxing might have been easy, just leave it sit out, lol.
What are you using to patch the shells? I've still got a few of my first wax burn outs that are cracked from when I didnt know any better and tried to melt the wax out slowly. Seems such a shame to waste them. Ps, what is that loverly car in the back ground?
To patch shells, I take some slurry and mix in a little fine silica and paste it over holes and cracks. I let it dry for an hour or so and repeat. Some times I will take the shell for another dip in slurry and another coat of coarse silica. Lets see some of your work! Got a YT channel?? oh... 1969 Jag E-type. We call it our rolling IRA. ;-)
@@jagboy69 Many thanks for the reply. 1969 E-Type..Wow what a cracking car. I've tried the above with some success in the past for cracks but I guess I was not clear. Cracked as, come off. I was thinking about using a plaster of paris bandage for a first wrap and then give it some layers of slurry. Or, getting a bandage and soaking it in slurry and doing that. Have tried in the past block molding surry (SRS) but that didnt seem to work.
@@ebayboy8172, Sorry, I misread your question. Okay, after your shells have been fired once and THEN got cracked. Apply the slurry paste over the cracks. Do it a few times to build up some strength to the cracked area allowing it to dry between layers. I can usually add a layer once every hr. Maybe 3 or 4 layers of paste. After it's dried, Heat the shells again as normal and go straight to pouring metal. Easy right? Now if you are still concerned you might have cracks. Heat the shells, allow to completely cool and leak check them. (COLD SHELL ONLY) Fill it with water and see if it leaks out. Keep in mind, shell is porous and water will leach through the entire vessel within short order. You are looking for a stream of water. Once everything is patched, allow to dry overnight and heat up again and pour your metal. If your cracked shell has exposed a large section, I would dump it personally. PoP, plaster bandages and fiberglass are probably not the best candidates for such a repair. Pop holds bound water and can cause a steam explosion. Remember, the beauty of shell is it's resistance to dimension change. I tap my fired shells before pouring and listen for the ting ting. If a shell has a crack, it's more of a thud. :-(
Have you tried my boil out method? It works a treat if the "plumbing" is setup correctly so wax flows up and out of the shell. Hope some of this helps.
Hi Sir! Good work! What refractory material did you use? And how many layers do?
erko slambekov That is suspendaslurry from ransom & Randolph and I used 6 layers on this one. www.ransom-randolph.com They have all the materials to make bronze casting easy and painless. Thanks for watching.
Hey Erko... R&R sells shell materials specific for cast iron or for non ferrous metals. If you buy from them, be sure you get the right one. ;-)
What are your thoughts on using Borax? I had begun to believe it was the best way to avoid air holes but from some other stuff I've seen the mold is the most significant factor.
That's a good question. I am running cmx silicon bronze and I have ZERO problems with metal porosity. Guys pouring aluminum usually have those issues. One method I've heard that works is to cover the bronze melt with crushed beer bottles. This would be a good idea if someone is making their own bronze. Failure is always one small step away with this stuff, so by using quality bronze, it's one less unknown. The ceramic shell is gas permeable so it does vent off air bubbles.
As you can see, I do not have to use borax or any other fluxes. Fluxing will seriously reduce crucible life. ;-)
@@jagboy69 So far I've made some good bronze with CU/AL wire. The purity of the metal because of the industrial standard seems to help. I get hardly any slag off the mixed alloy. I will try the ceramic shell when I start trying to make tools. For now I really just want to make nice polished coins and ingots in advance of making the tools.
@@brassmagnet4795 Go with what works right? I pay the 6bucks a pound or so for ingot silicon bronze at industrial metal supplies. Too many copper thieves these days so I keep paperwork on metal I purchase. 😉
good evening, what kind of welding machine do you use to weld bronze? If I want to weld with oxy acetylene what kind of antioxidant should I use, can boric acid be good? thanks for the availability and kindness, its movies are always very interesting.
Oxy acetylene welding bronze is very tricky and it puts tons of heat into the piece. I have an HTP Invertig 221 machine. Its overkill for welding silicon bronze, but it's a sweet tig welder. I welded this on DC at about 120amps with sil-bronze filler wire from airgas. Once the weld is polished out, it matches the cast bronze perfectly. Worth every penny. Some guys have the skill to do this with oxy/ace, I tried it once and made a mess. Good luck and thanks for watching!
I think boric acid like mule team borax from walmart should work as a flux. Let us know how it works for ya.
I use boric acid during melting, I put it in the crucible to bring out the impurities and it creates an antioxidant barrier, it also helps the fusion of the bronze.
It's funny, I've never used flux in any of my melts. I buy bronze ingot ready to go from industrial metal supplies in california. Runs about $6 a pound and so far has been very clean. I know someone that alloys his own sil-bronze in mexico and to cover the melt he crushes beer bottles to prevent oxidation. Crushed coal would probably also work I suppose. Small scale guys pump argon to sit on the melt, pricey for bronze, but necessary on some metals. Platinum is one of those I think. I wonder if boric acid would improve the fluidity of the metal? If it does, it might help with really thin sections, for now, my only fix has been to pour thin stuff hot and thicker stuff a little cooler.
to improve the fluidity of the bronze, you can pour a few moments before pouring a little saltpeter (potassium nitrate)
