Really appreciate the drawings 3:34 & 4:58 - Tight. 9:48 - Takes some experience to do that right; tip o' the hat.

I always enjoy the "I need a tool/gauge so I will make one" kind of jobs. Keeps the skills sharp. Good work 👍

[@ChrisMaj]

That's repair/ machine shop for you. You make it work.

[@DEL-ACTO-BO]

I am new to running CNC lathes and machining in general. I appreciate this channel and your content. I like to watch these videos to learn more while off the clock. Thanks, and great work!

[@ChrisMaj]

It's not really a learning channel, but I'm glad you like it 👍

[@michaelkoch2109]

Good job! As always! 👏👏👏👍👍👍 Greetings from Dresden! 🍻😎

[@ShainAndrews]

Simple. Put some bar stock in a machine. Press some buttons and 13 minutes later a finished part ;-) Nice work Chris.

[@ChrisMaj]

Yeah, that's what I tell people that don't have any idea about machining.

Крис, твои ролики хороши и как кино! Сделани мастерски и в етом плане. А профессинальний уровен - как всегда классний, висшей проби! Поздравляю с уважением. Да, в молодости очен любил полское кино. Почти все картини били на шедевральном уровне. Начиная с Цибулского...

Measuring thread flank diameter with the 3-wire-method (thread gauges, thread cutting tools, precision threaded spindles, ...): During my years on universal thread grinding machines in the Pre-CNC-Era (GUS Lindner, Kellenberger and some sowjet models) I made good experience with thread measuring wires in holders and thread flanks mikrometers. To make things easier (great OD) you can fix thread measuring rolls with plasticine.

[@ChrisMaj]

I usually just use little bit of grease and the wires stick really nicely. It's the diameter and large micrometer that makes it difficult and just having two hands.

[@friedrichkeul9791]

@@ChrisMaj I know, I know ... the problems with such diameters (and dimensions), large micrometers and calipers and the lack of a third hand 🤔.) 4 weeks ago I mentioned that I have 3 month of experience on a facing lathe Ravensburg and one year on a vertical lathe Froriep KE 14 Super (and a lot of other machines). With a Universal Comparator Gauge (dial gauge and gauge blocks) life becomes easyer and measurements more accurate (IMHO).

[@keyes_austin_trainingchann7443]

@@ChrisMaj what kind of tolerance range does a thread like this get held to? I know a class 3 on most smaller threads is about a .003" range

[@ChrisMaj]

@@keyes_austin_trainingchann7443 That is a class 2 and if I remember correctly that's 0.011"

[@bhekidlamini51]

I really like those Iscar threading inserts. I think you can also put a round or square grooving tool in that holder.

[@ChrisMaj]

You sure can.

[@xx96180]

Profissional, Nice.

[@johnlawler1626]

Great work mate👌 it takes a lot of skills to measure threads using wires 👍thanks for sharing 👍

[@ChrisMaj]

Yeah, that big micrometer doesn't make it any easier.

[@reinierwelgemoed8171]

Epic work. In my next life I want to be a machinist.

[@shortribslongbow5312]

Incredible work. :o)

[@PhilG999]

I still think it's interesting that the lathe ramps up speed on a facing cut to keep the SFM constant!

[@geoffgreenhalgh3553]

Great work. I used to hold the thread wires with putty or plastasine when checking thread size.

[@ChrisMaj]

I think I got pretty good at it. The tricky part is the large mic. Sometimes I'll just use some grease .

[@rotating-alfadiq]

Great job

[@mattiasarvidsson8522]

I use iscar all the time for making threads .. it seems like the only choice if u want a very good surface.. :)

[@marklowe330]

Nice job. I was wondering how you were going to check the internal threads. The same way I use to. Make your own gage by measuring it over wires.

[@chrisgilman33]

I was more amazed that you didn’t drop a wire when you checked the thread 😂

[@ChrisMaj]

Let's just say, I've done it few times before 😉

[@CraigLYoung]

Thanks for sharing 👍

[@MBTechnicalClasses]

Amazing,👍👍👍👍💯

[@HP_rep_mek]

Nice parts👍

[@robertoswalt319]

That looked like some wicked scarf coming off those threads. And using those thread wires look like they could cause some serious cussing at the end of a long shift

[@ChrisMaj]

Yeah, especially when one falls in your chips bin.

[@jimsvideos7201]

Some part of a telescoping hydraulic cylinder maybe? Nice looking bit of work, whatever it is; hopefully it's done now and you can enjoy your weekend,

[@ChrisMaj]

It's a nut for tail stock/ head stock, whatever that means. Yeah it's all done and out the door. It's my week off to spend some time with the kids. Probably no video next week.

Can any machinist suggest a carbide tip or hss for drilling SS

[@larsolav2009]

Question about the threading, it seems you plunge rigth in for each pass. Any reason you are not using 29 degree pnluge to make only one side of the insert cut? I usually do that on smaller thread sizes, but havent threaded this big yet, so just wondering.

[@ChrisMaj]

This is a cnc lathe, you can choose how you want to do it. In the video I'm using what's called zig zag threading. What it means is that you are using both sides of your insert.

[@Chiefs1582]

I also get to fight forgings daily

[@mftmachining]

No collegue around to help with the mic?...Bahhh....shame on them... :--D top-job as always, Chris an thanks for showing,

Haha, it's easier to do it yourself than having someone get in your way.

[@matthewbrawley1194]

Un threads usually have a . 0004 tolerance for gauges, would be nice to see that with your wires

[@ChrisMaj]

16.750" x 4 TPI 0.0004" tolerance? You're not serious. If I remember correctly there is like 0.011" tolerance.

Hi Chris I'm looking for a good single point threading tool do you like that one?

That's probably the only 60° threading tool I use. With one insert you can do fine threads and something like I did in the video, 4 TPI
