your incredibly knowledgeable for your age.But your true gift is the compassion you show for us who in spite of our old age are just learning a complex skill..
Thankyou
The look on your face at the beginning is priceless

Clearly she's been spying on me standing in my garage in front of my machine lol😋🤣
Glad to see a straight up tutorial. I don't watch too many 'project' videos because, well, they aren't my interest for a project. But straight up teaching is always welcome. Nice job.
Great video! I inherited a lot of lathe tools from my Dad who was a machinist for 55 years. There's a lot of custom formed HSS bits that I'll spend lots of time figuring out just what work was he doing with... Thank you for the great explanation!
Completely agree. I have totally done turning with a chamfer tool because it fit the job!
Or because it was already in position.
Neat!
Now I get to play "What is this thing for" the home version.
Thanks, and Meow to Sprocket.
This is one of those I don't know what to ask questions that I'm glad someone asked! And secondly, thank you for making this basic tools video... I can look a these tools and feel a little more informed than before I watched this... Thank you so much for sharing your knowledge with us.
Love the video! As a complete rookie it's great to find a video that starts with the basics and avoids technical jargon. Thanks!
I spent hours trying to grind my first HSS tools with no guidance, and thought for sure I must have bought a junk lathe 😂.
Now I feel ready to go out to the garage and try again.
I'm amazed how far I made it at work as lathe operator. 5 years of throwing carbide tools into the CNC and then failing so miserably trying to take .01" depth of cut on my own manual lathe with my own HSS tool. The most shameful part is that my job title is "tool maker". I've never felt like such a fraud.
This video and the video This Old Tony did on carbide in the home shop are excellent help for beginners. Love how accessible you keep the information without it getting dry.
This video is great for me, a beginner. Thanks.
You are for sure one of my favorite people. I seriously appreciate your humanity, strength, and humility. I really wish there were more people who had those attributes where I live. Thank you so much.
I wish I had seen this video years ago as I taught myself to be a 1950's machinist to support my car hobby. Very well done and informative.
None trivial amount of time. Is my new favourite statement. It's obvious why you said it. You gave me understanding. Thank you.
Lol my dog LOVES it when I scratch her back in juuuuust the right spot with high speed steel lathe tools. When I'm feeling fancy, she can have the carbide :)
Clears up a lot. Thanks for this!
This is very timely- I've just got my lathe up and running and am in the process of figuring some of this out. Thanks Quinn!
If you watch CEE cutting edge engineering out of Australia they use those round carbide bits to make plunge cuts to part pieces on hydraulic cylinders and leaves a surface ready for welding later.
@@TitoRigatoniexactly just the topslide on Curtis's lathe is about the same as Quinn's whole lathe bed 😁
Big round ones are strong for horrible gnarly weldcutting and interrupted cuts
Your combination of excellent explanations and clear, detailed images is really great. Thank you, this is really valuable.
Another great tutorial/explanation video.
Buying the preground HSS sets is often a cheaper source of HSS then just buying blanks themselves when starting out.
Then again buying second hand assortments are the best bang for buck.
As someone who is about to pull the trigger on buying a lathe and getting into machining with zero vocational training, this video is a great help. Thanks for this. 😊
One of the great things I found about grab-bag tooling is they often are great place to start out from. Suppose you need a 9/64" grooving tool you can maybe find an oddball grooving tool that is 5/32" . You can grind just one face and ... Robert's your fathers brother. Plus, the reliefs are all there already.
New to metal working and a friend sent me this video. Thank you this was a great over view and very help in getting my feet wet with all this. Love the Chanel.
Thank you so much for sharing your wisdom! This kind of video is invaluable for armchair machinists like me to get a good feel for the way one would tackle typical operations on hobby machines.
Thank you! I learned a lot from this video! I hadn't realized how important it was to have the cutting edge of the turning tool square to the work. Thanks for all the great information in this and all your videos!
Superb timing. I just bought a 13x24 lathe, and i bought some carbide tooling just because i did not want to learn all the HSS and grindings and shapes at the same time i learn to use a lathe. Now i have no excuses, and i can get some hss bars ! thanks, once again, you rock !
Excellent clear narration, no wasted words, thank you very much
I just bought my tormach lathe yesterday and I was overwhelmed by the amount of cutter I got. This video helped me a lot. Thank you so much for sharing your knowledge with us. 👏
Great video. I’m going to need to watch it more than once … and then start going through about 50 high speed tools I’ve inherited..
Blondi, you're so funny! Our metal shop instructor in high school was sooooo boooring that 98% of the class didn't know what we were doing nor why. However there was enough exposure to this great skill for some of us at least to remember it years later. We didn't learn much but now watching your tutorials and examples I am able to finally get it.
Thank you so much teacher!
By far the best explanation of lathe cutting tools I have seen EVER, thank you for that, youbdemonstrate clearly the angles and faces and reasons for the way they work
She said "Skookum" I knew i liked this channel.
Thank you for discussing tool post angle! As a beginner, I hadn't been able to find any resources that talked about setting that angle. I was mostly on the right track, but it was helpful to have someone demonstrate it!
This video is absolutely amazing!
I picked up an interest in hobby machining because of TH-camrs like you, Abom97, Inheritance Machining, and others.
Bought an old lathe at an auction that had about a thousand different tool bits and no idea what they were all for. Thank you for explaining the uses and applications for the different angles
Great video and most helpful. I'm a gunsmith not a machinist but I use my small lathe to turn barrels from barrel blanks and modifying factory barrels. Getting a nice finish when turning a barrel from a blank is so helpful. And bumping a shoulder back to get the front sight indexed properly is common and requires getting into a tight space. Thank you for explaining the tools to do those jobs.
I'm reorganizing my lathe tool drawer and putting them back in their correct containers (and labeling the containers this time). Your video was a great help in identifying some of them and their functions. Many thanks.
And the greatest geometry ever put on a lathe tool post is the circle.
Carbide button inserts make me stupid happy, one of the most satisfying cutters ever.
Thanks for doing this episode. It really helped me understand what I am looking at on my new lathe.
Thanks Quinn. I remember, when I was a young teen, (about 16), I was going to a Tech Trade School, (night school, while I was going to a different high school), where the old instructor, (Joe Fraiser) showed us how to grind a 3/8 x 3/8 square high speed tool steel bit to a 1/2" deep gouging tool with a 1/8" wide snout and a perfect radius on the end, to cut to the left and at the end to cut a BALL & Groove that would go inside a thimble cap on the end of our Screw-Jack. Tgen how to turn the radius inside the cap and then close the thin edge around tge ball with a brass bar an inch high and 1/2" thick. I can still see him do this Wah-La thing with his hand and he stuck his thumbnail into his forehead and scared himself. That brass pushed against the turning cap, rolled it closed so it wouldn't come off the ball. It was our SENIOR project. 3 levels high with threads turned on each level and knurled. He used a big 8" old fashioned bench vice to squeeze the bar handle on each end so it wouldn't come out. That was over 50 years ago! I still have that tool. I keep it lubricated. I made a similar one in tech school, after I graduated from high school, but it wasnt near as fancy. It was just a bell base with a short neck and a fine'thread 1/2"-28 screw and the closed ball cap. one of the projects in the Machine Shop class. I took tool & die, too. I worked in Job Shops till I changed carriers and went to Electrician when I got a real good job offered to me. Better pay and benefits and a pension...nothing like that was offered as a machinist.
THANKS QUINN, for your work and explaination.
Thanks! That was a great video and useful for me. My local used tool shop has bins of small used lathe tools I sort through and now I have a better idea what to grab for what purpose.
Thank you. Very clear and easily absorbed. Answered a lot of my questions.
This was great, when I got my lathe I got 2 lathes and did not really know it. The man had extra parts for everything and then I also purchased a machiest tool box with tools and I had now idea what half the stuff was for. So now I can go thru it and pull out what are cutting tools. I my still not know how to use them, but it is all a learning curve.
Hey Quinn!
Great video, Thanks.
I am a long time, amateur machinist and have pretty much, but not totally, figured out turning tools and the grinding and selecting there of. That said, your summary here is excellent and I’ve picked up tips and gotten explanations as to why things work, or don’t. It was a half hour well spent.
Let me add, Also, that your instructional capabilities are stellar.
well done....as a 60 year retired tool maker I much enjoy your channel ......hope you keep at it....best of luck...
Thank you so much and I'm glad I have come across your channel. So informative.
I have dived into the world of grinding my own HSS tools thanks to you. Even got my group lead into your videos amd we got the engineer's black book which i used as a guide for all my angles... despite being shat on by a bunch of old guys my surface finish is unbeatable and i dont need multiple zero passes anymore. But right when I get overwhelmed by all the shapes i been shown by old guys you drop this video so now im not as lost
Thanks for the information. You answered questions I didn't know to ask. Love your channel!
Nice clean presentation with lots of great info. Thank you.
Thank you again for the lesson Quinn.
Yay!! It's Blondihacks time!!
OMG, same! I too am super particular about the geometry and angles of my back scratchers. Pricey, but soooooo worth it
I've got a few hours in operating lathes, but I basically know nothing about them.
This is very basic foundational stuff that I need a lot- thank you!
I am an absolute beginner with a small lathe, so this video is going to be really useful information. Thanks.
Well done Quinn! I like ours inherited a bunch of strange tools that you helped me maybe figure out.
Hi Quinn👋,
You forgot one of our favourite Tools, the Diamond-Tool-Holder!
LG Lara
P.S. Great Video!
People may have noticed that a turning tool works better as a facing tool when withdrawing it instead of pushing it in, and you showed why, with the angles. When there's a hole in the part you can often get away just by reversing the direction of feed when you're facing while leaving your tool post square. Lighter cuts though.
The default direction of the cross slide power feed on old machines, like south bends and their contemporaries, is from in to out as well. I imagine that these 2 things are related. :) For example, when your lead screw direction is set to progress the longitudinal power feed towards the chuck, the cross power feed will progress towards the operator. Back when these machines were made, I reckon it was a significant time saver to NOT have to change a tool in a lantern tool post. It's the opposite on newer machines, I guess the advent of quick change and turret style tool holders made it easy enough to change tools that it made sense to change this behavior in newer lathes as well.
love the breakdown on tooling. I've been watching various channels on milling and machining and while they've been a wealth of knowledge, they never touched on the basics which was a little frustrating. will definitely be binge watching your content lol... subscribed and shared 👍cheers from Toronto ON CA
Thanks for the detailed explanations
Very well presented and thanks for the clarifications.
Love it. I'm going to start playing with all the tools the old guys who retired left.
Incredibly helpful video, thanks!
I have been searching for a video on this EXACT subject! Thanks!!!
The goofy song in this video is straight fire! Love it!
For a short video, you covered a lot of knowledge, Thank You 😊
Thank you love your vids I am consuming them all one at a time great work. Hear your up,here in Canada good work have fun keep up the amazing teaching that you are doing
Damn...I learnt me somethin' today...this is an excellent trove of information...thank you Quinn!
Yet another addition to the already extensive library of beginner's videos.
It's not the Adam Booth or Clickspring's videos that will convince aspiring hobbyists to take the leap, as I can attest to personally.
You’re absolutely correct: Quinn makes the whole process seem accessible to anyone. She did a great video on the different levels of accuracy, and how to know the difference between when good enough is good enough and when dead-nuts-on-the-money is absolutely required (and how most hobby machining falls somewhere in between). She makes it clear that learning this hobby happens in baby steps, and mistakes will happen along the way. She also makes it clear that those mistakes almost always can be worked around, and are always always a learning experience.
Clickspring, on the other hand… precision just this side of godliness and the patience of a saint. His videos are great, and his work is definitely something hobby machinists can learn from and aspire to, but that may be a bit intimidating to the casual beginner.
Excellent overview. It would be interesting if you followed this with a look at the “tangential” tool which is the ultimate “all in one” HSS tool. 👍👏👏😀
Wanna be machinist in my dreams. I learn so much fom this channel. Thank you Quin (sorry if I misspelled) you are awesome. 💚
Thank you for your videos, they are great for me as a beginner at the age of 52 I've always loved lathe work but now I am about to buy my first lathe, a myford ml7 from a friend.
Really looking forward to making my first project, maybe a hammer 😁👍
Great discussion/information
Some great tips - Thanks Quinn
Very helpful! Thanks for sharing your wisdom. 😊
Another great video Quinn! You do such an awesome job of explaining things without making the viewer seem dull. Thank you once again!
Also a good video suggestion for the lathe skills series is indicating the tailstock... i just recently got educated on it by an older coworker and figured out why things seemed off center that our shop makes on the lathes
Excellent video! I would have really loved to see you touch on braised carbide as well.
More informative than in my machining class!
Excellent video Quinn, many thanks!!
Excellent knowledge, It is a shame the industry has been dead for at least 60 years when every thing was imported from out side machine done and ship it. After Regan the machine shop died. I am one of thousands who raised a family with this trade (who to blame)? I hope when I die I go to machine shops in haven. And we where proud to be a machinist tool and die maker. THank you for your spirit to bring beautiful memories.
That face 🤣😆🤣 I think I watched that part 6 times in a row just dying laughing 😂
Special mention on the grooving tools for trepanning tools. Also no mention of your brilliant HSS tool holder?
One other type to be aware of are the shear tools. They’re uncommon, and not ideal on small, low powered lathes; but they’re potentially very valuable for those scrap bin mystery materials as they can achieve good finishes on materials prone to tearing or galling.
Your best intro ever!
Very informative video. Thanks for the entertaining information!
Thank you for this. I really learned a lot.
This whole time ,2years been watching you, and thought I had been subscribed !😜thank u for being u!
*Superb* video. Well done!
Like anyone with a lathe and LOTS of lathe tools in a rack behind it, I loved your back scratching joke.
absolutly a great presantation,new scriber here,greetings from north carolina
Awesome episode. Thanks!
That short one may have gone in a bar that can hold bits at 90° - and been used for internal threading
I was thinking that too, double ended so the bar could be both for boring and threading.
Very nice video. I learned a lot. Thanks!
I inherited my Uncles machine tools, some good and some not so good. The small lathe is an old Craftsman 109-21270 with variable speed motor. The machinist box with the lath tools looks like what you dumped on the bench. Not the most accurate lathe but I use it almost one a week to make tools or modify something. Comes in handy.
Thank you Quinn for a very informative video. I am more the wiser to the tooling I posses. 👋👋👋
Bonjour Queen,
As an amateur user of a Unimat 3 lathe who is learning on the job for brass and bronze, I find this video very informative, thank you!
