From one machinist to another, you are very good at what you do.

[@oifmarinesgt]

To be accurate, it's called a sheave. A sheave is part of a pulley and sheaves are used on cranes where the cables ride. I know this because I am a crane operator.

[@DodgeDhanda]

Hi Chris. Just discovered your channel & I enjoy how the machinery these days can do so much. I know you need to possibly keep the vlogs to a certain length of time & I was wondering if you could show the whole process from start to finish but speeded up & that way the whole process of what you do can be appreciated just like you did when flipping the pulley over.. Still enjoying what I'm able to see of the process

[@jackfitzgerald6927]

Chris, you always post wonderful videos and do such a fantastic job. I love seeing your videos and can not wait for the next one.

Liked the video. I believe a pre-forged pully would have saved a lot of machining time. But then again, if it's a special purpose unit manufacturing then I guess this is the only way to get it done. Cool process and cool video.

Chris the four 26MM holes you put in for the final operation, i didn't see in the print did you get permission for that or where they on the print, i also saw some large herring bone gears do you make them, i'm going through a gear box now that needs four made for it.

[@ChrisMaj]

Yeah, that 26mm holes were just for the final machining.

[@Kurokimachine]

Great work as always. I have always used round inserts myself for deep grooving, but have recently been using dnmg more and more for exactly the reason you gave

[@Xris-FJ1200]

Many thanks for this new great video ! I'm pleased to lurn all your technics with you and your vertical lathe. I have a question about the inserts. You always use "gold" inserts. Personnaly I have bought "nano blue" inserts" wich are very strong. Do you use them sometimes ? I have an old lathe (from years 1940, my neighbour gave it to me, it was from his grandad), but it is a very good lathe that is very precise, the clearance is abou 1/100 mm). Many thanks christophe

[@morefilm5859]

Well Done. I just wonder how you get the M16 positions spot on both sides as seen in the drawing.

Congratulations on the excellent work. 👏🏻 I would like to know how long it took in hours to carry out this machining?!

[@ChrisMaj]

Can't really talk about this job much.

Interesting to think about making the same part at a different scale, seeing the intro and drawing I thought there would be problems with chips getting stuck in the middle... I was amused to see the chips just fling out due to the revs! Similarly fun to see the coolant fill the dish and react to the movement, cool to see the fluid behavior, momentum and whatnot. How did you drain the pool before 15:20? a big straw?

[@truegret7778]

[@angeloangelucci717]

[@davidryle]

Good choice of when to utilize coolant. Sometimes the chip takes the heat away, other times not. Who provided the forging? Did you have to scale it before turning?

[@mrctools8352metalurgia]

Quantas horas de usinagem pra executar essa peça.👍🏻

[@TheJohndeere466]

I make smaller ones on a cnc lathe and just chuck on about 3/8" and do all the machining including the groove on the 1st side. I use a 1/4" wide kennemetal grooving tool and I program it to plunge on one side feed across and plunge again and feed back the other way alternating directions on each pass. It never stops cutting on the groove until I run the finish pass. These little grooving inserts break chips pretty well.

Bonjour, une question peut-être un peu bête : pourquoi ne pas faire une ébauche de la poulie venue de fonderie ou forgée ? Il y aurait moins de copeaux et de temps d'usinage, non ?

[@mikeydk]

I like the round inserts for grooves like that. But they are indeed a bit picky about cutting data to get the chips to break properly.

[@CajunCrustacean]

I think radius inserts are more of a necessity in manual machining. At least, for me they are. I don't even want to imagine trying to get a clean three-plus-inch radius with a pointed insert.
