Metal Casting at Home Part 86 Centrifugal Lost PLA Handwheels 

Wow, takes some confidence to spin molten brass around like that. Great procedure and fabulous results, master at work.

Your Sir are an artificer of metal. I ALWAYS enjoy these videos.

Experience is a great teacher. These pieces are quite big and easy to cast but if your casting pieces that have holes or small cavities you need to make sure the investment fills them up completely when you pour it. I overcome this by painting investment on the wax sprue tree with a small paint brush. In this way you can make sure all the holes and cavities are filled before you pour in the investment. The key thing is to avoid spending hours trying to file off and drill the casting.. Works a treat for me...

Lovely job! When you left the chuck key in for a moment I was transported back to my days at Brighton Technical College and the look on the lecturers face when my fellow apprentice turned on the lathe and launched a chuck key!

The centrifugal machine is working like a charm. I watched your experimental video. Really is wonderful to watch. Thank you .

Lo vi durante muchos años a mi padre hacer este trabajo. pero usando cera para los modelos.( El cual me enseño) .Verlo a usted hacer lo mismo con estas pequeñas piezas es emocionante. Muchas gracias . siempre muchas gracias. I saw my father do this job for many years. but using wax for the models (which he taught me). Seeing you do the same with these little pieces is exciting. Thank you . always thank you very much.

I love your centrifugal casting machine, nicely thought through and beautifully executed as is all your work. Best Regards Sarah

Always am learning something new as well as being inspired by your vids; thanks for doing what you do and doing it well.

That turned out perfect! And just a torch for melting so now furnace required. Thank you for sharing!

That is such a clever solution to a very tricky problem. Hats off, again!

You have this sorted rather well now. Fantastic results!

We like small here to watch you and learn these making techniques. We love metal cast work videos from Australia, England Wales and even here in the US we never tire of watching this craft. Centrifuge, we love this it really is neat to watch, though we do not see often enough. Very nice results, thank you. Lance & Patrick.

Oh Wow! I love your craftmanship! Your tractor is super cool too!

AWESOME!!!!! im engineer and i had never seen something like this!!!! the best channel of castings, you are the Granpa-Casting

OMG, this is the cutest casting process and miniature parts I've ever seen. You are a pro. I had to subscribe to your channel to keep watching your marvelous work. Thank you for sharing👍👍😊.

ever time im looking for some informathion on a project I always find myself back on your RU-vid channel :)

amazing, that would have to be the best casting technique I have seen to date, I have done centrifugal casting in the past but spinning the casting on its own axis. very very nice work!!!!

Wow, those tiny handwheels are awesome!

Beautifully done, you make it look so very easy, very well done sir!

Not for the first time...... Mind Blown!!! Your my hero.

🤯🤯🤯!! I didn’t even know that was possible that was friggin awesome 👏🏻 I’ve never seen that done before well done very interesting😀👍🏻🍻🍻🍻

finally I can see someone using vibrations to get rid off air from plaster. zillion thumbs up.

Wow they are beautiful! Brilliant method

Nice work indeed. Always amazing what can be done in the shed at home.

It is a wonderful thing you do in sharing your skills for future generations

That was mental! Never would've dreamed to do it like this.

Very good craftsmanship.

Pure genious! Little works of art!

Fascinating all the things you do i like watching your shows 🏅🏅🏅

You must be pleased with that. It works really well.

you are simply a master!!! Love your vids!

Glad to see your Ml10 is full of swarf ... like mine. Excellent video.

Well done, very nice work!! Chris

i have only seen centrifuge casting with gold, and have had spun cast grey iron, very impressed with this!

estupendos videos tiene usted unas manos, no me pierdo ninguno e aprendido mucho con usted gracias

Best example of lost wax casting (oops lost PLA) I have seen.Thanks for the fine video.

Excellent! Thank you for sharing! Greetings from Alaska.

Wow, so cool. So methodical and meticulous. Great video. Cheers. : )

Very inventive. Well done!

Nicely done.

Many thanks Mr Myford. Inspiring.

Wow...Nice finished product and a great video! I was holding my breathe though as you changed bits with that lathe chuck spinning. Only takes a fraction of a second to get a sleeve grabbed by that chuck, even for an experienced machinist.

Awesome video. Changing the tailstock drill bit with the lathe running, wearing long sleeves. You're asking for an injury to happen!

Just Wow (as usual) Regards from Dublin, Ruaidhri

A thing of beauty!

You gotta balance and shield that centrifuge or it's gonna be chasing you around the shop! You come running out of there wearing nothing but your asbestos nickers, and people will start to talk, and not in a good way! I was half expecting your brass to flow back into the crucible when it slowed way down. But all turned out well. You have a wonderful gift when it comes to moving parts, my friend. I like how you simplify everything without compromising form or function. My great flaw is that I tend to over-build my prototypes, and then after numerous mods are required... i get burnt-out at the mess of it all and end up quitting before things get perfected. Anyway. You done good, and i learned from your hard work. Thank you. There's just one suggestion i'd like to make. Would you mind speaking up a bit? I can't hear you at all! 😶

This is awesome! You need to add a counterweight to your machine in order to stop the machine from shaking

just beautiful

Super robota! Pozdrowienia od fana z Polski.

Clever, as always.

I'm very impressed with the quality of your diy spin casting technique. I will be using your method very soon. Thank you for another wonderful presentation!

Very Impressive !

great another thing i want to build and try out. this is genius.

Great video!

I'd say you have that centrifuge down. The detail on those parts was precise. You could clearly see the 3D printed layer lines and all. The hand-wheels look fantastic.

gracias por compartir tu conocimiento

I liked the red coral you made...

Great, great and even more great TFS "thanks for sharing" G :)

... you're the man ...

Thanks for sharing !

Brilliant!

Amazing!

Sir, you do very fine work. The production of these small doc's are the best. I do wish you would talk to us. I think your video's would be just that much better if you were to explain how and why things were done as you do them. Your video's about your knowledge and the sure confidence you show too all us about what, how and why is appreciated . Again thank you for showing the world your vast skills.

Add a cup of dish washing liquid - just plain old no nothing bargain stuff - into a 5 gallon bucket of drywall mud as well. It has exactly the same effect, FAR fewer bubbles in your finish coats. Bubbles in drywall mud are a pain in the ass because they never show up until you start sanding and it puts holes in your finish that you now have to put another top coat on... Dunno if it bothers you seeing the layer lines on finished parts but you can decrease your layer height. For super fine stuff that I create I'll take the layer height all the way down to .03, you can hardly tell it was printed at that resolution. Sure it takes a while longer but many modern slicers let you set different heights so you can change it for the connected arm that gets cut off.

That was nice.

Well. I feel stupider than normal now. You just did about four things I hadn't thought of yet.

That machine is terrifying. Imagine the crucible cracking while it's spinning up... that'd be bad.

Think you ....you are the best

So cool ! I like your videos, I come from China.

Impressive.

i love how quiet Myfords are

I see why VegOilGuy likes your channel enough to repeatedly give you an honorable mention. 🙂

some good tips on your channel even for an engineer like me

good job

12:00 Very good install !

you can hear the door slam shut as he turns the machine on and runs. LMAO. maybe rig up a lightswitch on an extension cord or something, lol

These castings are coming out really well. You've probably come across it, but a nice way to make small handles & knobs is to part off short lengths from heavy-wall tube and solder 6 of them around a central boss.

amazing

👍👍 fantastic

Nicely done. The centrifuge works well.👍 It'll be a while before I try spinning molten metal in a DIY machine. Explaining why my neighbor has metal splattered through their window is not a conversation I want to have. 😔

That is pretty goddamn clever.

So cool. You are a bad ass

Awesome intuitive skills though I did back away from my screen when the centrifuge ran up, molten metal on a workmate scary stuff!

oh so thats what the spinny thing in my school metal shop is for! my teacher told me it was for casting but i could never figure out what it did before now

Just wow!. Da bear sent me

cute as heck

Parabéns

I'm thinking that since you are bound and determined to go as cheap as possible, that you make a vacuum setup using the venturi principle and the faucet in your shop to draw the vacuum and a large pickle jar as the bell jar, in order to do a good and proper de-bubbling and then use the venturi vacuum again, along with a sheet of rubber and ano to make a vacuum caster. along with a plate of aluminum covered with a sheet of rubber to serve as a vacuum casting machine. It's much save than that spinning wheel of death that you have created, and it produces better castings. Thanks for the video. It was fun.

I wanna see that steam machine running!

Would love to see you do a casting video with 2 stroke stuffings cylinder head! Seems he's having a lot of issues and can't get it quite right.

Heaps good

You have knowledge of pattern making and casting well beyond most who utilise printers and you mechanical insight must steer you towards a certain build type of FDM machine. If you had to choose one which would it be? And no homemade numbers!

For such detailed parts I would recommend to use an MSLA 3D printer with so called "castable resin" (which is a special resin for lost resin casting). Those printers are not expensive anymore (see Wanhao D7 or Anycubic Photon). I really like your videos - lots of insider information. Thanks for sharing!

Fantastic casting results, but there is absolutely no way in hell you'd ever convince me to use this thing @ 7:01 I'll stick to my cope and drag for now!

I cast bronze using the same method. Don't know why you don't buy a rubber sprue base. This fits over the flask sealing it. Also I paint the sprue tree with investment before filling the flask, this stops air bubbles sticking to the pieces. You have about 10 minutes before the investment sets so I tap out any air bubbles with a stick. If you've got a large air bubble in the flask it can explode in the burnout kiln or crack... When it comes to drying time I leave the invested flask for about an hour. Its important for the plaster to be damp when you start the burn out.. Finally and the thing that worries me most is the centrifuge. I would never spin the machine without some kind of shield. If the casting goes wrong, which can happen on occasion, you'll have 1000c molten brass flying everywhere. I made a simple shield around the machine with hardboard and also a lid. as soon as the metal is melted I put the lid on and duck behind the shield, I then let it spin.. Thats a fundamental safety precaution. I've cast hundreds of times with this method without injury..

smart

In a way, it's cool that we can make these at home now, and in another, it's hurting the industry around them, but at the same time...considering the ridiculous prices some have gotten at (and mind you, i would've had no issues buying 50pcs at once) they kinda reap what they sow.

It was worth it.

Kelloggs Honeycombs!

Thank you for sharing, excellent video as always. Perhaps you could put some concrete anchors into the floor and bolt the centrifugal caster down on the floor? When not in use you could just unbolt it and store it elsewhere (just make sure to stick a bolt or something in the holes so they don't clog up). Did you have to loctite the hand wheels to keep them from spinning off? I thought from the video that you were gonna broach them square or something.
