[@mikemoore1821]

In an age where everything is drawn on a computer, most of your technical drawings look to be hand produced on paper by someone sitting at a drafting table. That's cool, and dare i say, a lost art! If i'm wrong, well that's cool too. Interesting work either way!!👍

[@popanollie1]

i went to school at a time where they didnt have cad and cam classes yet at every school, only the big city ones. so i got stuck with drafting and blueprint classes, and when i got out of school most business already started using cad and cam so i was kinda sol and havent used my drafting pencils since school like 20 years ago lol

[@ChrisMaj]

Us being a repair shop we get a lot of old drawings.

[@RovDisco]

There’s parts that I make that are from prints that are before the war. They are still being used and haven’t changed one bit.

Great video. Nice part. I enjoyed the twenty years I programmed lathes. Now I just work in my machine shop at the house doing what ever I choose.

Nice bit of turning and well filmed mate thanks for sharing 👍love the wet and dry for shim works well 👌

CNMG644 to moja ulubiona płytka - tylko grube wióry 💪🏻 😁

[@ChrisMaj]

Płytka dobra tylko potrzeba więcej koni pod maską żeby ją całą wykorzystać.

[@yajtramer6913]

Amazing

[@clayz1]

This is exactly what I do. CNC lathe, manual toolpost. Manual tool change. Seems archaic, but the other tools never get in the way, so in some ways you can do more types of cuts. My lath is 14.75” over the saddle, 90” or so long (don’t quite remember the exact length).

[@ChrisMaj]

Automatic tool holder might be a good thing for production work, but for one-offs it makes no sense to me. Sometimes I switch tools 10 times a day.

[@wendull811]

I do the same thing at my job. I use the same lathe as him just it is 315" long. And we have an old enco tool post on it. So we can change our cutting tools like a dove post but we can also move them in a arch every 9 degrees.

[@jankociubinski5423]

Lots of material turned into shavings, maybe forging or casting?

[@ChrisMaj]

Being a repair shop there isn't always time for forgings.

[@lucianfuehrer6908]

Thank you for all the great videos. Could you make a video showing your methods of loading/unloading the large parts and how you indicate them in? Thanks!

[@ChrisMaj]

I mean, with the overhead cranes it's pretty simple and most shafts have centers on both ends and I also have a center in the spindle ,so basically I'm working between centers.

[@darkmp40]

Nóż w uchwycie w imaku - tego jeszcze nie widziałem 😁

[@jimsvideos7201]

This is an expensive way to make more than one or two, but it makes sense for that.

[@ChrisMaj]

There's just no time for forging when customer is bitching that he needs it ASAP.

[@jimsvideos7201]

@@ChrisMaj Don't they all do that for everything though? 😀

@@jimsvideos7201 I don't even pay attention to all that RUSH JOB, ASAP, HOT shit. Even if you put 4 exclamation marks it's still gonna take the same amount of time.

[@missingno303]

it got so bad lately here, some work is 2 month over the deadline and the material is still not here

[@captcarlos]

Nice work, thanks for filming it. I notice the live tailstock centre, is that the same lathe with the thrust bearing failure? Just curious.

[@ChrisMaj]

Yes it is.

[@captcarlos]

So have you spun up the replacement thrust bearing yet?

[@ChrisMaj]

@@captcarlos Yeah, works like a charm. I hope it's gonna last as long as the old one.

[@Chris-kk8xg]

nice indicator :)

[@ChrisMaj]

Budget friendly 😉

[@Sil-Gussinklo]

Nice job!😎 How make you the centers at the begin?

[@ChrisMaj]

On a horizontal boring mill.

[@nevermind1O844]

Why wasn't it done as a shaft with a keyway to fix the roller to it!? Wouldn't that drastically reduce cycle time and waste of material? Are there stability concerns?

[@ChrisMaj]

Well, that's not really my call.

[@philosoffer]

Nice. 75% shavings.

[@ChrisMaj]

HOT JOB, no time for forgings.

[@cryoine7194]

0:54 ah yes the song of my people lol

[@natedawg003]

How long are your typical cycle times for the shafts you usually do? Do you ever have problems with material flexing/bowing when removing a lot of material? If so how do you deal with that

[@captcarlos]

If you notice Chris will usually rough all surfaces leaving enough material for two finish passes. Which allows fine tuning of the final pass to size and surface finish. This time the flame hardening was between roughing and finishing which probably ment he left a bit more on in case.. I'm sure he will tell us...

[@ChrisMaj]

O man, my cycle times are all over the place. Some parts are 3 feet long and 5" in diameter and some are 13 feet and 18" in diameter.

[@wendull811]

I run the same lathe as him but longer and my cycle times can be anywhere from 10 minutes to 5 days. Depends on the shaft sizes as he said. We do 2inch diameter shafts and up to 20 inch diameter blanks.

[@user-tb8zf4jk8u]

How you make a live center inside a 4 jaws? chuck that really nice may I have information please

[@akulawien1975]

What Material are the Shims you use for protecting the Jaws? I use sometimes Duct Tape.

[@aaaooaao9949]

Looks like aluminum - something softer than the workpiece.

[@berntinulkshredder]

I love the brass plates they work cool. Just cool.

[@currentbatches6205]

0:44 - The draftsman needs to show spaces between the feature lines and the dimension lines. Neither you nor me would ever confuse the two, but the kid breaking in on that machine over there might. Poor documentation. 4:16 - My taste; music < sounds of cuts. 4:16 and on: Interesting how the vid frequency/lathe surface speed control has the lathe turning backwards now and then. Or your editing... 5:28 - Posted by a machinist who still has all 10 fingers! 7:12 - Zero chatter, tool 12:42 - Got some of their stuff here; no gripes. Checked against Starrett and Mititoyo, fine. 14:22 - Seems the speed is stepped? Concrete saws also 'step' down in frequency; what gives? 14:58 - I'd be proud.

[@ChrisMaj]

I don't really pick my drawings, as long as I don't have to guess any dimensions cause the drawing was photocopied 100 times I'm happy. I'm only trying to use music where there is no sound like hyperlapse or photos. 4:16 it's the hyperlapse video, no editing done. It has something to do with the camera speed or something 🤔 Yeah, I still got 10 of them and I would like to keep it that way 😂 That was a short piece so no chatter problems. Maybe SHARS won't last as long as some of the expensive brands but they work OK. I don't use them for measuring tools but other things are fine. It's a constant surface speed. Yeah, I'm proud of what I do some might like it, some don't, but that's what I do and that's how I do it. People like it, awesome. If they don't I'm not gonna cry over it.

How do you like the TNMG insert? We always use a DNMG 443.

[@ChrisMaj]

I only use them for finish cuts. You get 6 corners, chips don't get stuck between the part and tool.

[@wendull811]

Both centers were done on a horizontal boring mill.

You convert metric drawing to imperial?

[@ChrisMaj]

Yeah, all of the machines are set for imperial and we only have imperial measuring tools.

[@lordbartosz9416]

so whats the deal with the aluminum plates and chock ?

[@ChrisMaj]

Nie wiem czy masz coś wspólnego z tokarką i jak ci to wytłumaczyć. Przy toczeniu większych kawałków głębokość skrawania i posów jest dość duży i czasem "czasem " sztukę obróci w szczękach i wtedy szczęki zostają obtarte.

@@ChrisMaj okay .. ok then you can easily switch over .. the question came because I saw that drawing was metric and you have converted to inches
