I don't mind at all when you mix up the contents with casting, sheet metal work, restorations, and various other builds. I like how you mix topics, bring us down to the details at time, share the mistakes, and how you salt it I up with various stories from your life experiences. Keep up the good work!
I really appreciate the positive feedback. I know not everyone is int oall this stuff, but I also need to get on with projects which are important to me.
You're definitely a man of patience. All that work casting to come to results less than what you expected would crush me. Great video! And by the way, I think the casting videos are extremely interesting!
Thanks. I think I am making progress, as the clear coat burned out without ash. I just didn't put enough time into preparing the model. Next will be better.
It was really interesting watching the casting even if part of it didn't turn out. I am a machinist and for whatever reason we don't recycle the chips... I am machining a 6in X 9in X 3in box out of a solid block and I couldn't bare to see all those chips get thrown away so I have been gathering them in buckets to hopefully cast. I imagine mostly I'll be turning them back into aluminum bar stock to be machined again. But all the tips and tricks are very helpful! Great video! Love seeing the casting content too! Its amazing how it seems like as soon as I want to do something my favorite TH-cam channel has JUST made a video showing how to!
Aluminium swarf is problematic, as Al Oxide has very nearly the same density as pure metal, so it neither float well or sinks. Since Al oxides immediately on contact with air, each of those chicks has a little oxide shell, which will be suspended in the melt, kind of like a slushy. You are better off casting with either virgin ingots, or at least start with castings like wheels or cylinder heads. With Iron or bronze, the oxide is much lighter than the melt and floats to be skimmed off easily as slag.
The traditional way to mix plaster is by sprinkling the plaster into the water, that way you don't introduce air into it, if your plastering a wall it doesn't matter, but, for casting, mix with your hand, slide it into the plaster, keeping it below the surface. Having sprinkled the plaster in there should be practically no air bubbles. I don't "know" your investment plaster, traditional plaster takes one volume of water to one volume of plaster. less water makes it stronger, more, and it's not taken up by the plaster. When I say "know", I mean that plaster varies depending on it's age, the older it is the more it will take on water with time, until it gets to an age where it won't "go off" any more! I love plaster!!! Cheers, Matthew
Not sure if it’s available on your side of the pond, but instead of using a razor for getting parts off of the print bed I use a metal bladed Scotty peeler. They are intended to be a sticker/label remover, but they are designed to be worked underneath something tight which makes it really good for getting under the part. It’s a lot easier to control than a razor. Also, this was a worthwhile bait and switch.
That music around the 10:00 → 12:00 minute window was intense. I thought something was about to catch on fire. OOF, those way wipers though, ouch. RIP. Great video Mr. SMP!
Hey mark. Did I ever tell you that My farher have worked over 30 years at a Iron casting factory. They shut down the furnace about 15 years ago and moved the casting to norway and only have a warehouse here in Randers. He started in the casting area and is now a salesman in denmark. They make manhole covers and all there is with that. My first job was at the factory. He ran a big manual vertical lathe they machined some of the casting on.
@@RotarySMP I think some have a small library that they just go through again and again, but I think you got a pretty good sense of what works for your audience. At least I like the variability in the music selection
@@vincentguttmann2231 Thanks. The license free music library YT offers got not new music from the end of last year till last week, but luckily they have started adding some more.
So youtube just recommended this channel to me. I am pretty sure I recognize the name from a old metal casting forum I used to frequent. looks like there are some interesting things going on here. subscribed...
this channel is simply awesome, I love your videos and I look forward to next sunday. Great work mate, you know simply everything. Maybe small gaps in geography :-)
I actually did the opposite with my lathe. I 3d printed in abs the wipers and used the original shell to bolt them on. Basically a replacement for the rancid felt that came with my 80+ year old lathe.
The waywipers will function better if you load the felt up with wayoil before screwing them on , other than that great episode , always a joy to see you come up with new ideas
I would think that the printed wipers with felt would be more than sufficient for the task. Still, I like your attempt to cast them. Nice casting setup. That's on my list of skills to pick up before I die. At this rate, I need to live forever. Haven't done any casting since High School, 50 years ago. They actually used to teach things like that at my Tech school, back in the day. I've been collecting bits and pieces for a furnace and hope to put one together in the not too distant future. Did you make all of your casks?
Yeah, I cast the aluminium flask parts of the flask I used on this video. I have also made a few woooden flasks, which are plenty good enough for the amount i use them.
Viennese neighbours seem to be very forgiving! And seeing that repurposed fire extinguisher, I thought…. Now that would make a real good vacuum chamber for the Beatles! No idea of the wall thickness of those things, but it’s got to be enough to machine a matching lip or groove into the shells and put an o-ring in - presto, no pressure? As for the pump - that could be your next project! 90% of machining is to make tools, right?
I like both! I tried some casting on my beltgrinder wheels in aluminium. Casting aluminium comes very handy, if you don't have enough stock material. BTW: That maho stuff is the best on your channel.
Thanks for your feedback. I will be using the Maho more once I get a little further along on the Schaublin restore, as I will need to make some new motor mounts. It has been a bit neglected lately.
George IV looks good, and the AL casting turned out well. If those temporary way wipers stay on there too long, they may become permanent! (how it usually goes)
Can you 3D print the wipers with a flexible filament and back them up with a sheet metal cover? I'd aim for a squeegee lip to scrape the ways. Felt is likely to retain CI or other particulates. Let's hope you don't need a George VI. The last one did a runner:)
Also, printed _turbine_ blades? Huh. I knew they had printed fuel nozzles flying, and I figured the first printed rotating parts would have been compressor blades.
I am surprised as well. They already have forged Titanium Aluminide LPT blades in the Leap (the ones I showed), but are going to additively manufacture them for the GE9X. I hate to thing how much the development of that material and process has cost so to bring it to market.
@@RotarySMP That's entirely possible; aviation remains an interest but I've been out of it as a profession for about five years and haven't kept up in detail.
These figures are just over 200mm tall, so a resin printer would be expensive. I really dont have the time or money for that. The advantage of PLA is that it not only burns out cleanly, but it doesn't stink, which is important for me. I am making progress. I learned on this one that clear coat also burns out without ash, but I didn't put in the effort to prep this well enough, and seal all pores.
I didn't realize there was a Beatle named Richard. Peter maybe. William? I guess what I'm saying is that the part at 2:43 is a little Freudian. In that it looks like a wiener. 😂
why do you still use cura slicer i may ask? i really reccomend Prusa slicer. imo it has a way better interface, it slices supports much better, and allows you to do way more advanced things
I tried Prusa, but had some issues with bed levelling which i worked around with micro steps. The G Code ouput by Prusaslicr kept overrighting the microsteps. I just printed Ringo with Cura tree support and it worked really well.
Try sand casting if you make more way scrapers maybe? To be honest I prefer machining and machine related videos. Casting can be cool if it is for functional parts, but I'm not really interested in casting statuettes or other aesthetic things. Speaking of which, how goes the rebuild of the new lathe?
What an incredible project! It has been amazing to watch. I'm a little curious - how do you feel about it now? The reason I ask is that I've got a 10x22 lathe (just the one) and I'm considering a CNC conversion. I make a lot of consistent parts and it would be a huge help. I do make custom things too though... So I'm always afraid I will shoot myself in the foot. Even tonight I was easing into some cuts thinking "that's the kind of tactile feedback you don't get with CNC" So my dilemma is - once one is proficient can CNC basically be a more sophisticated (or at least accurate) way of making parts that you get used to thinking about? Can you do manual turning just via MPG, or do you end up using gcode and models for everything? Am I gonna curse myself if I give up the handwheels? Thanks and I can't wait to take an even deeper dive into all your videos!
Good questions: - how do you feel about it now? The mini lathe is still the same flexible noodle, lacking mass it was before. As such it is only nice for very small parts. I much prefer turning parts on the Boley, even though it is very worn. - Tactile feedback I cant really answer this. I used the mini lathe for years under TurboCNC with no MPG at all. That was good as TCNC had some good canned cylces, and it taught me G code. I only put a single MPG on the minilathe, with a selector switch between axis. This is typical on a mill, where you only jog for set up, but I think this was a mistake for a lathe. The Schaublin will get a dedicated MPG on each axis. Schaublin did that on the follow on 125-CCN. How that feels, I dont know yet. I tend to only make one offs, so the manual jogging with MPG's I expect to be nearl as fast as the manual boley lathe. - do you end up using gcode and models for everything? Lathe part geometry is so simple, that I nearly never make models. I used the TurboCNC G77 code which did incremental passes along features about 80% of the time. In LinuxCNC I still need to set up Andy Pughs Lathe macros, which will give conversational programming. I expect with that implemented, I will probably conversationally code 99% of jobs directly on the lathe.
May be dip coating with plaster in many layers before entombment in more plaster will help surface quality by a long way. PS this has worked well for the last fifty years.
Shell investment casting is a different technique. It uses a very different type of plaster, which I have not been able to obtain. This casting showed I am on the right path, as the clear coat burned out without ash, but I didn't take enough time to prep the model and really inspect it to be sure there were no voids.
Too bad about those way wipers. Might have to try aluminium instead for them... Speaking of vacuum casting, I saw a video on here recently of an "affordable" home shop setup for that...
Spending infinitely more time trying to print and cast parts that can be made in minutes from barstock....story of my life in a nutshell....it's not the destination, it's the blah, blah, blah along the way 🤣
I quite enjoy the casting to be honest. There's something very appealing about the idea of making parts completely from scratch like that. Y'know. Unlike where you take stock material in pre-made dimensions and just lego them together like a total cheater :D
Hello, I thought you might have another Wah-Wah moment with the casting of George, but it is looking a lot better than George the first. Take care. Paul,,
looks like you use silicabronse is tricky with small parts use 10% Zinn bronze for the small skulpturs and more air raisers thin channels ... the mix I gave you let the air better out thru the material
I put a bunch of way oil on them. Yeah, failures would a major set back. Then again, the N1 turns pretty slow on those largest engines, and the LPT mass is pretty low, so if they fail, the engery releases is low enough that they are normally contained by the case and fall out the back as swarf.
@@darkmann12 I used onshape, and really liked it, but since I monetised the channel, I would need to take a comercial license, and cant afford that. FreeCad is a bit clunky in it's interface. I am only a beginner at it, but Onshape and Catia are much more intuitive to use.
I need the thickness. I'll try a number of thin layers of that stuff in the tube. I dont think Satanite is sold over here. A subsriber is sending me some ITC-100 though, which I beleive is similar.
@@RotarySMP Satanite is like clay. I have like half an inch plastered inside a forge. ITC100 is very similar. If you have any places that make forges/furnaces around you can probably get both.
You don't need a brim if you are 3D Printing Parts with such a thick foot print. Deactivating saves a few seconds and a need to clean the parts from them.
Does Niko, have a comment about plastic way wipers, and is he a BEATLES FAN, i'M SURE HE WOULD like george the 4th of course as a gift for the number 1 Fan.
@@RotarySMP plastic way wipers is not professional. cutting felt with worned out cutter is not professional. Not receiving cookies since now 17 days is not professional. Stop being so unprofessional and get me bloody cookies. Or Georg the 4th. I might get few quid for this one. And trade them for cookies.
Maybe use some 100% biodiesel or rapeseed oil for when the neighbors are there? They will soon leave due to the french fries smell making them hungry 😄.
@@RotarySMPTwo years later and I'm here watching OLD casting videos because I'm too impatient for the new one you promised! 😂 If you haven't updated your kit look into farriers chaps (horseshoeing) long, leather, split down the middle type of apron. (or get the proper thing like Myfordboy finally did)
I see you have a pressurized oil reservoir, get yourself a fuel nozzle from a furnace. New is like 20 euros. Here is what I do. Oil diluted with diesel about 50-50, pressurized to 3 bar. I have a car oil filter inline just in case. Stick a piece of burning paper in the furnace, air on, fuel on from a needle valve, woosh, clean flames , happy neighbours. No preheating BS or anything. I also tried all the "brutes" and other "awesome" burner designs. After using a proper nozzle, they all suck :)
@@mardu1541 Cool. My compressor is a bit flakey and sometimes trips out. Since it is fixed in the basement, having this happening is the main reason I didn't go to a atomising burner.
@@RotarySMP Actually I don't mean those atomizing with air spray nozzles. I mean the ones that only need fuel pressure. Something like this. katlakeskus.ee/et/pihusti-otsik-delavan-w--et-53.htm So you really only need air once, to pressurize your fuel tank, just like now.
For casting videos check out Perry at th-cam.com/users/swdweeb. Lots of description of theory. I really think he does a great job in explaining the process.
Don't you have a CNC mill ? Why not just machine the way wipers out of billet aluminium ? I know your trying out your casting skills but this is what happens when Kiwis move to Europe, they over complicate things and lose the practically of doing something simply just for viewers.
I don't get why you always call your solutions temporary.
It's only temporary if it fails
I live in hope :)
Temporary until when it fails.
Then we do another temporary fix
@@traitorouskin7492 In the grand scheme of things... aren't all fixes temporary? All repairs futile?

@@NicoCarsAndCookies Nope. It is finished. I have been using it for years. It is just ugly.
Have you thought about making the wipers from hdpe? Seems like it might be a good material for the application.
Good idea. I have only ever printed PLA
I think that is what Keith Fenner (TH-cam) did a few years ago, only he CNC machined them out of HDPE.
@@EngineeringVignettes I was already setting up for that casting session, otherwise I would have machined them.
I quite enjoy the casting to be honest. There's something very appealing about the idea of making parts completely from scratch like that. Y'know. Unlike where you take stock material in pre-made dimensions and just lego them together like a total cheater :D
I find the challenge enjoyable also
Nice Video as allways, of course Metal wipers would be nicer, but i think the plastic ones should do fine.
That is what I am afraid. Tempory permanance.
Try casting the wiper caps with flatest surface facing up next time, should come out better.
Thanks for the tip.
Hello,
I thought you might have another Wah-Wah moment with the casting of George, but it is looking a lot better than George the first.
Take care.
Paul,,
Incremental progress
I work in an artfoundery we use a mix of 1/3 krossed form 1/3 keramiccross and 1/3 of plaster... why not milling those smal parts?
looks like you use silicabronse is tricky with small parts use 10% Zinn bronze for the small skulpturs and more air raisers thin channels ... the mix I gave you let the air better out thru the material
Thanks for the tip
Try using urethane for the way wipers instead of felt. Won’t carry swarf so readily.
Thanks for the tip.
No oil on the way wipers? I like the short forays into the airline industry. I hope those printed blades don’t wind up in the cabin....
I put a bunch of way oil on them.
Yeah, failures would a major set back. Then again, the N1 turns pretty slow on those largest engines, and the LPT mass is pretty low, so if they fail, the engery releases is low enough that they are normally contained by the case and fall out the back as swarf.
What CAD software was that?
FreeBSD, just switched to it
@@RotarySMP ah, it reminded me of Onshape quite a lot
@@darkmann12 I used onshape, and really liked it, but since I monetised the channel, I would need to take a comercial license, and cant afford that. FreeCad is a bit clunky in it's interface. I am only a beginner at it, but Onshape and Catia are much more intuitive to use.
How’s things going on the Schaublin?
Been too busy with castings, I’ll restart soon though
Try some Satanite for the inside of the door of the furnace.
I need the thickness. I'll try a number of thin layers of that stuff in the tube.
I dont think Satanite is sold over here. A subsriber is sending me some ITC-100 though, which I beleive is similar.
@@RotarySMP Satanite is like clay. I have like half an inch plastered inside a forge. ITC100 is very similar. If you have any places that make forges/furnaces around you can probably get both.
2:15 - 'ere the hex nut on the knife turns into a knurled head screw...
Yeah, I should have edited that out :)
Surprised you didn’t mill the way wipers
I was tempted. Might still do that
I can't tell if I'm being stupid but I can't figure out if there was a reference to AvE or not 😂
No, I dont this it was.
Will we also try to cast the path* cover 🤣
Path cover?
@@RotarySMP *way cover
You don't need a brim if you are 3D Printing Parts with such a thick foot print. Deactivating saves a few seconds and a need to clean the parts from them.
Thanks for the tip
I would like to see some videos using "the turd" to make parts.
He tried, but a turd makes turd parts.
That is a pretty good summary :)
For casting you need to watch videos from Mr Pete he is a mater at it
Yes, I like his videos as well.
Does Niko, have a comment about plastic way wipers, and is he a BEATLES FAN, i'M SURE HE WOULD like george the 4th of course as a gift for the number 1 Fan.
I hope he doesn't read this. Kindness confuses him :)
@@RotarySMP plastic way wipers is not professional.
cutting felt with worned out cutter is not professional.
Not receiving cookies since now 17 days is not professional.
Stop being so unprofessional and get me bloody cookies. Or Georg the 4th. I might get few quid for this one. And trade them for cookies.
@@NicoCarsAndCookies Hi Nico,
Cookies get earned.
Bait and switch alright...
:)
6:40 - "I am 100% doing it this way for technical reasons, and not because my wife found a chunk of plaster in last week's birthday cake."
:)
It's not the casting, it's the arts and craft projects combined with the Beatles. Those are two subscriber killers.
Yep, but I still need to do them, any I need to keep in the practice of making a video a week. The lathe content will start again soon enough.
It looks like 2girls1oven at 4:58 didn't work out for you.
Not really.
Air is an insulator... shouldn't worry too much about them ;)
Good point.
Maybe use some 100% biodiesel or rapeseed oil for when the neighbors are there? They will soon leave due to the french fries smell making them hungry 😄.
Yes, I use waste veg oil. I guess they were not hungary
you need an apron that's fireproof
doing casting in your jeans is just asking for trouble
Good idea, one of those long leather welding aprons would be an improvement.
@@RotarySMPTwo years later and I'm here watching OLD casting videos because I'm too impatient for the new one you promised! 😂
If you haven't updated your kit look into farriers chaps (horseshoeing) long, leather, split down the middle type of apron. (or get the proper thing like Myfordboy finally did)
@@jimurrata6785 I got the leather chaps. My factitious daughter calls then "butt free chaps " :)
I see you have a pressurized oil reservoir, get yourself a fuel nozzle from a furnace. New is like 20 euros.
Here is what I do. Oil diluted with diesel about 50-50, pressurized to 3 bar. I have a car oil filter inline just in case.
Stick a piece of burning paper in the furnace, air on, fuel on from a needle valve, woosh, clean flames , happy neighbours. No preheating BS or anything.
I also tried all the "brutes" and other "awesome" burner designs. After using a proper nozzle, they all suck :)
I'll do a quick cast iron tonight, I'll try to shoot a quick vid just for you :)
@@mardu1541 Cool.
My compressor is a bit flakey and sometimes trips out. Since it is fixed in the basement, having this happening is the main reason I didn't go to a atomising burner.
@@RotarySMP Actually I don't mean those atomizing with air spray nozzles. I mean the ones that only need fuel pressure.
Something like this. katlakeskus.ee/et/pihusti-otsik-delavan-w--et-53.htm
So you really only need air once, to pressurize your fuel tank, just like now.
For casting videos check out Perry at th-cam.com/users/swdweeb. Lots of description of theory. I really think he does a great job in explaining the process.
give us some updates on your schaublin kind sir....some of us are waiting
Sorry about that. SWMBO was also waiting. You know who wins. :)
I when you do video’s…. Any videos
I appreciate your support. Thanks for watching.
Holes like French Emmental not Swiss cheese. Come on. You are a Schaublin owner, you shouldn't make those kind of mistakes !
You caught me out there. Sorry. :)
I've got serious trust issues with you now after this video.
It was always going to be an abusive relationship. Ask Nico:)
Don't you have a CNC mill ? Why not just machine the way wipers out of billet aluminium ? I know your trying out your casting skills but this is what happens when Kiwis move to Europe, they over complicate things and lose the practically of doing something simply just for viewers.
I needed a bait and switch, and was doing the casting anyway :) The simple solution is the 3D printer plastic. Should last for years. :)
I enjoy all the kinds of videos!
Thanks for the feedback.
