[@chirots]

I am a hobbyist living in rural area North of Thailand. Having no background in machine learning, only learn this from KZbin and Google. Learning a lot by watching your videos on many topics

[@jimflinchbaugh335]

I want to thank you again for the great channel, There are a lot of great machining and welding channels out there but 2 stand out, Yours, and Jody at Welding tips and tricks. You both provide a great amount of content in a relatively short presentation. Others, who I really like like Mrpete and the like, are really good info, but a 45 minute video with 15 minutes of content, gets hard to stay engaged with. find myself fast forwarding through a lot stuff. Thanks for the great work Tony!

[@Makercise]

The end of the video was a hoot. thanks for the explanation of feeds and speeds. I do not have a machinist background, but I am getting a better understanding with your help and the good book.

[@ericennenga7218]

..loving the humor. As a woodturner I finished a little bit smarter about cutting speeds after your explanation. Thank you.

[@coyote0216]

I'm in the process of making a fly cutter based on your video tony, when in the exact same stage of making the 10 degree angle, the switch of my mill melted too. Guess I'm following the tutorial to the spot. Except maybe that I'm using a round stock steel, didn't have a hex :)

[@cylosgarage]

I hadn't looked at how many subs you had in a while, and was shocked to find that you only had 86 thousand. You are by far the most undersubscribed KZbinr I know. Keep the greatness going and you'll succeed I guarantee

[@MobiusHorizons]

I truely believe TOT is the highest quality instructional video of any kind I have seen anywhere on youtube. I could not agree more. I'm not a machinist, but these videos fascinating. Even my wife, who is not mechanically minded, enjoys watching these videos because of the great production value and sense of humor. Keep up the good work!!!

[@marioeldridge8049]

I agree! Found TOT while searching for CNC Router videos and haven't looked back. Easy to listen as he walks us through the videos and amazing what I've learned to date. Keep up the great work Tony!

[@ghosttwo2]

[@operator8014]

YOU'RE SO EDUCATIONAL!! I LOVE IT!! I'M YELLING BECAUSE IT'S IMPORTANT!! I've seen all of your videos, and this is easily my favorite channel on the entire internet, followed closely by clickspring.

[@ThisOldTony]

Thanks Brad!

[@Elektronaut]

I notices the surface finish and thought that that must have to do something with the rpm of the lathe and wondered how this exactly works. Seconds later you explain it. Love it!

[@SlowEarl1]

Thanks for doing what you do. Love the effort you put into your videos.

[@ThisOldTony]

Thanks Earl!

[@atomead]

Dang, a change in surface finish due to turning speed ? I thought it was the growth rings of the steel

[@puzzled4163]

If those are growth rings;He should use a circular saw with appropriate blade that away he would get an even cut across the grain.

[@drmodestoesq]

Yeah, ironwood.

[@AOZMONSTER]

I was just thinking about that hazy area just before you mentioned it. Look at you go!

[@johnathancorgan3994]

Heh, I don't even do any machine shop type work--I just watch these because they are so well written/scripted/edited. Every new video on this channel is a treat.

[@ThisOldTony]

Thanks Johnathan!

[@morganargus]

As field service I am impressed that the FLIR was used for troubleshooting. Bravo, not many people know about that.

[@pjhalchemy]

Thanks Tony, no need to apologize. Best explanation yet of why the surface finish changes on a lathe. For earballing I love the Wixey...the square is nice too. Hope you find the contactor easily no fuss no muss, low duckets....~PJ

[@XavierBergeron]

I'd rather have two parts than have to wait longer to have the full length! Triple pun surely intended. Love your work!

[@vernonkarm8016]

Flycutters are great for some materials such as plastics and other soft materials. Many people see them as "old school" facemills. They just have to be run at slower feed rates and rpms; mostly because of the unbalanced nature of the tool. If used properly, they can produce a better finish than facemills. I think it is funny to be making a flycutter using a facemill. Great job Tony. You are the best.

[@RambozoClown]

Another thing is that it is easy to grind a custom tool for a flycutter. I did that once to make a large threadmill to cut a strange profile multi-start plastic cap thread. Also shop made gear cutting is often done with one, too.

[@bikefarmtaiwan1800]

Hey Tony! Thanks for so much input in 2016. Happy new year to you and your family. I recommend your site to lots of people! Excellent job in all respects.

[@patrickholmes001]

I was just talking to a friend about surface speed the other day, and I keep trying to get him to watch your videos; so I think I can finally get him hooked with this one! Hope the mill doesn't take too much to get it back up and running!

[@janrie7330]

When you were facing that hex stock I noticed that surface finish changing because of the change in material removal rate, and then you talked about it. Now I consider myself a psychic, lol.

[@jasonyannuccelli2499]

Mate.... I just have to say... even tho you are very clever and obviously Uber experienced from doing this you’re whole career, you still take the time to explain everything. I love that ! Although being 50+ I’m very new to this and just lap up every word. Great sense of humour too which makes learning much more interesting. If all the teachers back in school were as interesting and funny as you I would have learned considerably more and would probably be a rocket scientist by now 😊 Looking forward to part 2 👍

[@azyfloof]

Oooh! I'm super glad you did that "filler material"! I wondered as soon as i saw it what had caused that difference in surface finish :P Now I'm aching to see part 2, if only to find out about that contactor :O

[@ronpeck3226]

[@SkullyWoodMetal]

Tony, I learn something new with every video. I have an old lathe an it came with a bunch of HSS tooling. I wanted to get "fancy" and upgrade to carbide tools but it appears I will do fine with what I have. Since I am just learning anyway it is better to start slow. Very entertaining as always.

[@ThisOldTony]

I've slowly started moving over to almost all insert tooling.. mostly because I find it cheap at flea markets :) -- but I'm glad I started with HSS and turn to it when I have a finicky problem to solve. What one learns sharpening their own HSS translates into all the other tooling that's out there.

[@thecogwheel]

High speed steel is greatly preferred by the Dutch and Scottish!

[@MrMadDrago]

[@felixdietzCGN]

aaaaaaah not only a 2-parter but also a serious cliffhanger, damn you tony for making such entertaining videos!

[@justtim9767]

Great explanation on cutting speeds.

[@ipullstuffapart]

Since he mentioned the automatic variable cutting speed based on the diameter modification, I'm really tempted to do it to my lathe, it's running a VFD so it would be pretty easy

[@KnolltopFarms]

It must be a weird feeling on a manual lathe to have it running up as you face something, LOL!

[@StefanGotteswinter]

I ran a manual Weiler Practicant VC for some time - It had the constanc speed feature...real scary when the machine turned up to 3000rpm when facing something... (Yes, the max. speed could be limited if the setup did not allow such high rpms..like a offcenter clamped part on a face plate)

[@ThisOldTony]

I assume you'd have to feed the VFD positional information from your DROs?

[@ipullstuffapart]

You would, and your control could likely be doing a zero on the centre point, setting the desired speed and a maximum RPM you would let it go to, maybe a percentage of the initial RPM? To stop whoopsies

[@RossWilliamsDC]

Why are facing cuts so satisfying to watch? Is it just me? 🤩

[@Wongsterwish]

New Year New Lathe!!! Blessed New Year, Tony. Keep the videos coming!!!

[@jeremyindenver]

Again, excellent video. You're on the forefront of making KZbin machining videos, seriously, you're on the cutting edge (adjusted for part diameter and rotation speed) awesome video production. Good job.

[@asyxcv14]

I really enjoy your videos! I can get very good tips and tricks for my work. I'm learning a mechanical in Germany and have a lot of work with the lathe or mill to do. Interesting to see, how you are calculating the rpm. I've learned that Cutting speed is: Speed=pi*diameter*rpm. So slightly different calculation of rpm as you do.

[@ThisOldTony]

Thanks.. and I think that's the same formula, just solve for RPM since speed is what you already know (target speed).. assume pi=3 and there are 12 inches per foot and you'll get the formula I used. If you're metric the constants will look different, but same formula.

[@proteinaggie]

Loved the technical talk in the middle! Thanks!

well, here I thought this was about fly dissection - still very much enjoyed and learned from this video. Thanks Tony

[@MakinSumthinFromNuthin]

I think you should have used your time machine to go back to yesterday when the mill was fine 😉 Hope its an easy fix...

[@Pythnn]

Mills are more powerful than time, you know this.

[@willfrancis858]

One of the very first things I learned was RPM = Cutting Speed * 4 / Diameter. In a lathe Diameter is your workpiece, in a mill it's your cutter. With your example of a 3" workpiece at 1000 surface feet/min Cutting Speed, that comes out to about 1300 RPM, so your 1200 RPM is good and it shows. By the, say, 1.5" diameter you'd need 2,600 RPM to keep from falling out of the ideal range like you did and your surface finished suffered. The very rare Monarch 1000EE lathe is an example of a manual lathe which often came with a constant cutting speed feature. Maybe the Monarch Series 60 and 61 had it, too.

[@ThisOldTony]

I think Acer? made one or two but I'm not surprised to hear the Monarch did too.

[@JyrkiKoivisto]

It's a bit of a bummer that your mill started to misbehave. I hope you will get it sorted out. (Or more specific I know you will) I have the same ISO/INT/QC 30 spindle taper on my mill and any new tooling that you make for it is something that I look forward to see.

[@button-puncher]

Thanks for the explanation of the surface finish change. Makes perfect sense once you go through it. I do wonder about the cutting tool radius vs finish. I've got some more learning to do. :) If I had to guess, maybe it's because the large radius makes for a more gradual entry into the cut? Instead of a sharp point on a carbide tool? More of like an ice cream scoop than a spatula? At a microscopic level, the sharp point is chipping instead of shaving? Carbide hardness playing a role in the chipping due to the tools rigidity?

[@rc166honda]

The old "to be continued" trick. haha, good stuff.

[@iRobotsGamer]

"Since this is probably going to be a short video and I need some filler content..." *creates video in two parts* Lmao. Glad you gave the cutting speed explanation though.

[@Herr_Scheissemann]

Hey Tony, considering that the linear speed of each minute diameter of the work face is supposed to be linear with the rotational speed when the cutter is "fed in", then the ideal rotational speed should be inversely corelated to the linear speed. That means if the linear speed is 0 because it has 0 in diameter then the rotational speed should be infinity rpm. That also means no matter how hard we try we can never reach perfect face finish because until now I never heard any lathe that has infinity rpm! My God Tony, your wisdom is too much for my poor little brain to comprehend!

[@clayz1]

You definitely owe us an apology for that.

[@iamawatermelon9299]

the funny thing about to do lists is that then never die, however you do so keep that in mind when putting stuff off

[@joshuabaughn3734]

Oh I hate it when that happens. For us it wasn't the relay for the motor it was a pneumatic reservoir that blew in the cold and the replacement overloaded and shot across the shop like a bouncy ball. Another regulator further up the line solved the problem. Note for newbies, make sure that the reservoir is rated to the pressure of your line or it will blow. If not, then regulators will save you having to buy reservoirs constantly to replace the blown ones 😒!

[@allankorte3753]

Tony, you've inspired me to jump in, and I've bought a lathe and a mill recently. I repaired a hydraulic cylinder and ended up with a rod about 4" in diameter and 20' long. (it was slightly bent). I was excited to have this material for practice and fabrication. Can you tell me what it is about chromed cylinder rod that you're not a fan of? The more I know about what it is good for, or rather, what it isn't good for, the better off I'll be. Thanks for all your awesome content.

[@AzCcc]

I was about to comment asking about the surface finish, then 5:18 happened ! Is my intuition off or is it more intuitive to decrease the speed (or increase the feed) the closer you get to the center instead of increasing the speed ?

[@AzCcc]

On a second thought, RPM = speed/diameter ==> speed = RPM*diameter so to keep the speed constant we need to increase the RPM the smaller the diameter gets which is probably what was said in the video.
