Degreed "Jeweler" here. In school, all our "practice pieces" were mainly from Brass (even back when Gold/Silver were relatively cheap). So a smelting tip for you ... add a few pinches of "Flux Powder" to the crucible ... it draws impurities out of the melting metal and draws it to the top; also easier to collect the slag just before your pour. Wondering if a smear of conductive grease between the 2 Brass surfaces would help rotation ... like Permatex 22058 ? Brilliant job !!!

@ckmoore101

That is literally the worst thing to put on there. Dielectric grease is not conductive. Its whole purpose for being is that it doesn't conduct. But there are conductive lubricants out there. Permatix 22058 just isn't one of them.

Hallo Andrej, meine Berechung hat was sehr änliches ergeben. 21mm*74 abzüglich ein 22,22 (OK... stimmt er mag die glatten Zahlen), bzw. 20,4 abzüglich Gewinde gemittelt 21,8. Bei der Schraube habe ich mich am Bild auf der Waage orientiert... Damit komme ich dann auf ca. 148mm und den Hexagonteil habe ich auf 20mm mit einer 4mm Abschrägung geschätzt. Das mit der M10 Schraube hast Du wesentlich besser abgeschätzt, da ich nicht auf die Idee gekommen bin die Umdrehungen zu zählen, die Kurtis braucht. Habe optisch geschätzt und 20mm angenommen. Beim Material jedoch habe ich "abgerundet" 8,40 ist meine Dichte. Beim Aufschmelzen von Messing oder Bronze verdampft ein Teil des Zink und Bleianteils (habe ich bei einem Glockengießer gesehen, die ettliche Barren Zinn in die Schmelze nachgeworfen haben...OK... ist hier Messing und nicht Bronze) Kurz: ich hatte 1884,2g berechnet... und aus beruflichen Gründen habe ich einen Faible für Schnappszahlen, darum ist meine offizielle Schätzung 1888g Schöne Grüße aus Bayern

Great job, and great comments as well. I've avoided making one on the few jobs it would be useful, and I really enjoyed all the different bits and pieces that put this together. Very nicely done, a fine piece of gear is finished.

Cool to see the big stack D shout out! Love his videos too! Won’t guess the weight as I won’t use one but amazing video one again guys! Love having a beer in the shed and watching the stuff you make weekly! Keep it up you legends!

Wide range of applications of that Knipex pliers is really impressive. Machining that brass like butter shows the quality of your cutting tools and power of your lathes. It also depicts the range of material hardness you're dealing with on everyday basis. The clamp itself is the epitome of applied art and design - 100% of function enclosed in 100% of form, 0% of bullshit. Excellent video, both on Karen's and Kurtis' side.

That thing looks beautiful. I love brass.

Impressive build quality from start to finish with home made brass casting ! 🏆🏆🏆

I'm not a machinist, so when you show that you are using a TNGG insert, I'm always wondering why and when the different types of inserts are used. I look up and see the spec sheet shows that it's pure tungsten carbide with such-and-such a hardness, and it comes in various grades. The type of coating is specified - I used to be in disk drive manufacturing, so I think CVD must be chemical vapour deposition, but there's also "PVD" and "NO". It might be informative some time to explain the different types of inserts, and when you use them. Thanks so much for your very interesting videos.

At a guess I’d go for 637g. Love the videos guys they are always interesting to watch

I love the giant pliers you used to lift the crucible
