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

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.

[@stevemcgarrett303]

Wow. That's a fancy pulley. Nice job!

[@SFish-wr4kh]

12:50 i love how you turned off the coolant because there's enough held in the part to keep the tool cool.

[@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?

[@zoltannagy1813]

Very nice work Chris. That machine makes a change from the usual centre lathe. How long did it take overall to machine?

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

[@Problem-attic]

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?

А я не представляю, зачем здесь ЧПУ . Обычный лоботокарный или карусельный станок для одиночных деталей. Дешевле будет намного. Их ещё со wwII много сохранилось

[@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.

[@slidebed]

Wonderful, you must be worth your weight in gold to the company you work for.

[@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.

[@warrenjones744]

A thing of beauty Chris.

[@ronaldfairhurst2914]

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.
