The Sapphire file is beautiful

why brass though and not copper?

8:16 🙂 Did you do that or how? Please explain

it must be said that you dont actually need a deadly silica powder to do investment casting, specially made dental investment plaster is far more capable of achieving cleaner and desired results and is much cheaper, that said the results may vary since dental investment is expected to be used with a 4,000 lb casting machine, not a homemade vacuum plate. we had a casting machine for our dental clinic and laboratory for years and did all kinds of things with it beyond just making porcelain fused to metal crowns/bridgework, from making jewelry to making replacement parts for precision instruments, but the huge investment in this equipment definitely shows its value. i must also say that the metal used in dental investment casting is not brass, but talladium/tilite, a complex alloy comprised of ceramic titanium alloy composite, titanium may have much higher melting point than brass and at such temperatures brass may literally evaporate and vaporize.

Cheers Colin. Big fan of your work, thanks for checking us out!

Maybe you can send him a broken kayak paddle Colin.

Holy crap, a Colin caught in the wild! Love your stuff! :D

Wild Colin sighting!

I love my watch making lathes! The best setup was like having a complete machine shop in a suitcase. In fact I drove the other members of my rockabilly band King Memphis crazy machining things on your with the band! Voltage inverter in the van powered my sewing machine motors.

What kind of things to you make? I used to work for an engineering company in Sheffield and they had me using a traditional milling machine to make drill heads. I was only 17 at the time and quickly got bored of the repetitious nature of it and left to continue my studies. Now I'm older I have a renewed interest in going back into engineering, I just want to be sure it will be a stimulating profession. Any thoughts/advice?

@@silverbullet2008bb I wish I could help but I did say “seen it all”, not “done it all”. I was just a production machinist. I started in the 70’s, a high school grad on Davenport automatic screw machines. Very fast and intricate machines that were purely mechanical. No hydraulics or pneumatics involved. The last half of my career in a different plant started analog and morphed into total CNC by the time I retired. That was a challenge for an old schooler who took pride in grinding and setting all your own tooling. Those skills were suddenly not needed. By “seen it all” (an exaggeration by the way. I wish I had) I loved discovering the super talented custom machinists in super custom machine-shops. It seems like they perform magic.

@@ridermak4111 Your experience sounds familiar. Our company didn't have CNC machines as they were quite new back then and we only had hand operated milling machines. The company owner was a masterful machinist, some of the things he made from a block of metal blew my mind. I've done boring, i.e. the boring of cylinders using a boring machine, and yes, it was very boring! I worked for GKN at one point making cylinders for Volvo engines but that was almost all automated. In the end they closed our foundry to move it to China! Apparently the Chinese would do a 12 hour shift for £3 whereas they were paying us £14 an hour.

The best job is to go on the dole my friend so that you can practice your hobby at the same time😄😄😄

Unfortunatly true, this country is on it's last legs now that being on the dole pays more than being a skilled engineer.@@johnhili8664

My recommended is clearly just UKposts throwing shi at the wall and seeing what sticks. Maybe 1 out of 100 I actually watch or even pay attention. Compared to other platforms like tiktok's FYP, UKposts's algorithm is absolute garbage.

Hahaha, i'm so glad i'm not the only one that thought how much this clip resembled Clickspring's videos :) Still a bit of way to go, but yes, the path looks clear. Sure Chris is happy that others share such passions.

Add narration to these and it would be right up there.

Stefan Gotteswinter does this in a production environment. He's my favorite machinist on the internet.

Clickspring will kick this guys ass he good tho i will say that

It's unintentional ASMR and I love it.

Yes, I was truly amazed by the workmanship as larger Stirling Engines, despite being awesome, are easier to get running as they can power through minor hiccups they encounter.

@@agiliteka ha ha ha you don´t know what you are talking about :D Stirling engines have zero power, cant even start it self

​@@jarniskatLiterally any type of engine with only one piston has this problem.

@@SenkJu ok literally kid! you don´t know much... there are and were many engines with only one piston, as an dirdbike, moped, outboard engine and and many more like on the old fishing boats that had a sound like "pop pop pop pop" because you were able to hear every stroke. Do your self and every one a favor and use your brain!

@@jarniskat Something tells me you have not as much as completed a decent 1st grade finger painting. :P

send it out for chrome plating, You'll gain 0.0003 inches on all surfaces so take that into your tolerances. But you'll get that mirror smooth finish.

You are absolutely right. Both engines make for great projects and although hot air engines are certainly more finicky, there's something particularly satisfying about them! Thanks for watching.

Hi Sam, our design process varies a lot depending on the project. I'll be honest, this one I designed as rough technical drawing on paper and then built, making changes along the way, sometimes making parts multiple times. The engine you see in this video is actually V2, once I had it all figured out.

@@chronovaengineering Maybe add a 2nd channel for longer videos with your design process!?!

@@chronovaengineering could you also share some of the fails and thing you learned that wouldn't work? would be super interesting

Is it possible to geht your plan ? I would Love to build one by myself😊

The rollers are great. Not quite as precise as a proper dividing head, but very useful nonetheless. When cross drilling, I almost always go in with a centre drill or spotting drill first. Now I'm wondering its power output too! I think I might have to measure it.

@@chronovaengineering another "tiny" challenge! Beautiful work....
