As a full-time manual metal lathe operator, I endorse this content. It's clear, accurate, well presented; and I observe your blessedly minimal use of The Mandatory Pun. Thanks, Quinn!
your content keeps me happy , im learning how to walk again with a prosthetic leg a bad car accident took my wife and daughter , the other driver fell asleep at the wheel and died as well, you videos are in a way very calming and i can see a new horizon in machining thanks
Indeed, there is a meditative and cathartic facet to machining in general, as well as Quinn's style/vibe. =) I find it helps keep me kinda sorta somewhat a little bit more sane... sometimes.
My condolences and I'm glad to hear you're learning to live with the tragedy you went through. I can relate to how you feel about Quinn and her videos. Some people just give off a natural "glow" about life in general that soothes or brings joy to those around them and she definitely fits in that category i feel like. There's been quite a few times I've had videos playing in the background while I'm working in the shop and Quinn is one of the only ones i don't skip over it it's something I've already watched before. Between the vibe the videos give off and the wealth of info there's a lot of rewatch value.
Hi This is Jayant Mashankar. I am a Chemical Engineer. An Expert in Process Equip ment Designer.But my passion was always Lathe and Milling M/C. After being inspired by your tutorials I finally bought a Lathe And a Mill. Now Ihave started using both machines. I am now 63 yrs old.
One minute after publishing - and I was the fifth to hit the like button. So there are more people knowing that this lady rocks and hit like "in advance" 👍
Jesus ! I'm new to this thing (just bought my first mini-lathe)...and I've been fishing around all kind of videos and tutorials for weeks...and finally found this woman...with the most well explained, perfectly articulated, highly detailed lessons for people like me (total noob). Thank you my lady...I'm devouring your videos.
I always enjoy the basics videos. They remind me of how much I have forgotten. Or need to learn. Or why I hate something. Or what is the airspeed of an unladen African swallow. Wait, what? Nevermind. Thanks, and Meow to Sprocket.
I’m so glad I found your channel. Until last Saturday I had no idea that I needed a lathe but by chance I stumbled over a video made by you and got hooked directly. I’ve never used a lathe and have no clue what to use it for (I’m a desk jockey and shuffle a lot of paper) but I became a believer and hope for an ephiphany because otherwise my wife is going to say derogatory things to me. After I saw your video I was convinced and just waited for the right moment to jump the gun. I didn’t have to wait for long though. My wife had to run an errand and I seazed the moment an bought one as soon as she slammed the door. That’s my modus operandi, it’s easier to be forgiven than to get permission.😂 I missed that you need a lot of tools as well so now I’m waiting for my next opportunity but she’s much more suspcious now so I’ll have to be very careful. I’m a fan and hope that I’ll understand 50% of what you’re saying shortly.😁
I have a mini mill and a mini lathe, and I am very good at what I do. Unfortunately, what I am very good at, has nothing to do with either a mini mill or a mini lathe. sigh... Excellent presentation, excellent understandings, I truly enjoy learning from you. You explained many of the issues I have encountered while boring. I am very glad I have subscribed with you. Keep up the good work. John
I could of put my name on your Post & it would have been 100% accurate - Had my Sherline Lathe for 2 years & Sherline Mill about 6 months… Learning curve is so steep I’m getting nose bleeds…🤓
Extremely well presented, no lengthy pauses, or "uhms" beautifully done, clearly very knowledgeable! I am certain I will learn a lot from you, thank you!
You are my most Boring influence......thank you for being here when things get boring.....well done Video.....thank you Quinn...cheers for cold and Rainey Central Florida , Paul
It took me many years of watching Kijiji, but I finally got my first metal lathe. I've been watching your videos for about a year and every time I see how much you do with such a small machine it inspires me.
Some of these I'm going to have to watch more than once to remember all the details. The diction is as good as if it were scripted, but it seems to be spontaneous, amazing. Everything makes perfect sense. It's quite the experience, a mix of "Oh yeah, now I remember" and "I should have thought of that" and "Oops, I wouldn't have thought of that!"
Awesome video. I wish this kind of content would have existed when I started machining. Happy to see my solid carbide bar making another appearance. I have found the High polished uncoated insert I sent you in the kit to be the best for brass over the tin coated insert.
If you've got a small lathe, another very handy thing to have for creating holes is an Annular cutter. You can get them wicked precise, and they'll run WAY better than a drill or a milling bit, and way less work than running a hole and bringing it to size with a boring bar. Plus, instead of a small mountain of chips and swarf like a drill, boring bar or the like, they leave you with a slug of offcut that's still very usable for other small parts. Normally you get them for magnetic drills or specialty drill presses, but you can get either adapters or just annular cutters that will fit your tailstock. Basically, since you're only cutting the circumference of the bore, and thus moving that much less material, they need much less power to punch through even the thickest and hardest stock, they're very resistant to chattering, and they make dead clean cuts with a pretty damned good finish. And, they work great in mills, too. Depending on precision needed, I either just run one on size, or run one slightly undersize, and bring it in the last few thou with a boring bar. (Also I know you probably already know all this, Quinn, but the other commentators might not, sorry if I'm just telling you what you're already well on top of.)
Quinn you might be a little eccentric, but if that was a bad thing would you have that nice shiny silver play button? Supposition aside I can say that you're an excellent instructor and that your cinematography is to a high standard.
I was doing a simple boring operation on the end of a part and having a bit of trouble setting the angle on the bar for clearance. due to lack of experience I wasn't sure how to correct this. so I watched your video and you actually addressed my problem. thanks so much for sharing. i always learn something here. And hey, who doesn't love a girl who can machine or weld.
This is the first time I've seen the negative rake on some boring bars, especially the smaller ones, explained, great thanks a lot! have seen a few of your vids now, so thought I'd better subscribe, cheers, Dave
Very helpful! I've been noticing a lot of spring in my tooling. I'm new to the lathe and using a Craftsman/Atlas 12" x 36" lathe. I was boring today and could not get my carbide insert bar to cut worth a darn. I ended up flipping the insert holder upside and cutting on the opposite side of the piece. It worked well, but i know that's not the right way. I'll try better tomorrow with my new knowledge. 😅
Most model engineering books call for the trinity of "drill, bore and ream" for e.g. cylinder bores. The drill hogs material, the boring bar fixes eccentricity and out-of-roundness, and the reamer is for surface finish (and final size, though the boring bar could do that).
Very nice. Especially the info about inserts and cutter geometry. I'm generally lazy and just ask my tool supplier what i need and use what they give me, but it's cool to have the whys and wherefores explained.
Some boring bars can be fed in on a surface, i used to work with ISCAR boringbars that had a 12 mm insert, and you could put these on center and make a hole that usually came out just over 12 mm, without drilling first. then Finish with the same tool, and the holes would come out nice.. Did it a lot in Toolsteel (D2)
Hi Quinn. Thank you for the video. I learned some new things to help with boring. I want to also suggest a micrometer stop locked to the bed of the lathe to help bore to a depth. I set the cross feed to zero, adjust the micrometer stop to the depth I want, use the power feed to get the carriage close to the stop and finish moving the last .040" by hand until I hit the stop. When I finally get the bore to size I touch the carriage to the stop and then turn the boring bar to center to clean up and flatten the back wall.
I did actually make a bed stop. Unfortunately this lathe is too small for it to be very useful. There’s rarely enough space between the carriage and head stock to use it.
Towards the end of the video, I was thinking: "Couldn't you just get rid of the drill cone with an endmill?" And then you explained why this doesn't quite work. Thunder stolen. I bought a job-lot of old tools on eBay a while ago and one of the gems in the box was a really tiny HSS boring bar that looks to be home-made. It's one of the most useful lathe tools that I own. I'm dreading the day that it breaks: I'm simply too hamfisted to make another one myself.
Nice video. I seem to find myself shaping bores, cutting O-ring grooves and even cutting snap ring grooves in internally splined bores...all to often. All of these challenges increase the likelihood of instant catastrophic tool failure from chip welding or oopsing (that is really a thing). On the side of my lathe I have a Mini Maglite clamped into a 1/4 inch aluminum bar which pivots on a bolt with a wingnut and a second bolt as a hard-stop to the center of the bore. This backlighting is very useful. Aside from needing batteries often and bashing your leg on it when it is in the down position, at least until you learn to turn it off and walk around it, it's very cool.
@@greatestevar What? The flashlight that shines through the chuck? Old 13 × 40 drop gap and a Chinese remanufactured geared tilt head mill with power feed. Self trained bad habits and flying carbide. I wouldn't stand there if I were you.
Hi Quinn, another Great Video as always. I really enjoyed it. I am going to finally get a chance to try Boring some Holes after ordering some Boring Bars in different sizes. I thought you would have a instructional Video on the process, and sure enough! Thanks for all the Videos. They have really helped me through this new Hobby of mine. I’m really finding out the Cost of this hobby though. Like they say, if you want to be a Millionaire. Start with Ten Million and take up Machining as a Hobby!
HA!!!. I always wondered where the term spring pass came from. It's a pass to take out the spring from either the part or the tool. I just could never figure out where that term came from
That was great. The only bit of missing advice was that I should have watched you video before doing my first flat bottom blind bore 😀. I made all the mistakes but your explanations helped me understand where I went wrong, especially that I should have tried and avoid doing flat bottom blind bores.
Excellent discourse on lathe boring Quinn. Have you tried using a 2 flute milling cutter to cut a hole/pocket, then index the cross slide to increase the diameter using one of the cutting edges, I think you will work out where the orientation 😉. Thanks for boring, sorry, sharing. Groan.
Sensei Quinn, very impressed with everything about your Videos⭐️⭐️⭐️⭐️⭐️ I’m a total Greenhorn Hobby Mill & Lathe Operator…Actually “Operator” sounds too official for my Skill Level… I’m more of a “User” or “Hack” (UH)🤓 anyway the Sherline Lathe I own is the 4000 series which is the smallest. I purchased it after I totaled up what I’d spent in 18 months to have custom aluminum parts made for the 1:25 Auto Models I build. [was enough to have purchased the New Sherline Lathe + several new attachments & tools] … 👉Anyway I’ve made most of the parts that I had hired this Very Skilled Lathe Operator to make…. With the EXCEPTION of {Wheels or Wheel Sleeves- I want to learn the technique’s necessary} ❇️ ❇️I’ve never used a boring bar tool. My concern is the the largest Aluminum Rod Stock I will be using is only 3/4” OD for 90% of the Wheels or Sleeves needed. And the other 10% is only 1” OD Aluminum Rod stock. ❇️❇️❇️I luv those Index Cutting tools you Demo in your video, I purchased a set of 5 1/4” Index Holders complete with the Inserts 2 years ago for $20 on Amazon & they have been Performed Very well for every part I’ve made to date. ❓However I’m not sure of the {TYPE or SIZE} Boring Tools to purchase for the small 3/4” OD Aluminum Stock needed for these Sleeves…🤔 ❓What type of Boring bar cutting tools would you recommend for this smaller than 3/4” ID Aluminum stock I’ll be using❓ Thanks again for an excellent video, your style of instruction is PERFECT for my ADHD 🧠.. I’m so glad that I stumbled into your YT channel & now FOLLOWING. Lee aka: ☯️ZenModeling☯️ 🤓
Could you do a video on cutting saddles in flat stock to perfectly mate the diameter of round stock? I made a keyed shaft and use a horizontal mill cutter the same diameter of the piece I want the flat stock to sit on. Then I made a jig for the tool post to hold my flat stock and feed it into the cutter with very shallow cuts. Very time consuming with two thou cuts. Gotta be a better way. Especially on an angled piece with anywhere between 30-60 minutes of angle.
This vid was just in time. I'm working on a back plate for an uber sweet bison chuck i scored from a friend. "hashtag definitely sponsored" Anyway, need to bore the register for the spindle, literally came in to search vids for exciting tips and boring content... And this was sitting on my home page. Serendipity? why yes, yes Seren, it is dipity. Very dipity indeed.
A boring bar cuts only in one spot similar to a step drill. But the step drill has the advantage of having the opposite side of the cutter pushing against the inner face of the material. Could it be possible to make an insert that cuts on one side and the other side would be smooth and slide on the new freshly cut surface. That cutting tool would be on an pivot point and after each cut, the tool would have to be turned slightly to expand the radius. The bar would only move in and out along the length.
I've in general have noticed that with boring and it's not just here, in other aspects of shop working like welding, one often never truely 'masters' an area of work. There's that imperfect element to it until the moment of retirement. Always room for improvement. So the term ' work in progress' is often the constant. Which not everyone seems to have that basic grip on. I only seem to bore maybe at best 3 times a year so trying to keep in mind the technical aspect and remembering it can at times be an enemy.
One thing to make sure of when flattening the bottom of a hole is that the cross slide actually has enough travel for the cutting edge of the boring bar to reach the centreline of the spindle. Believe it or not, some import lathes (not mentioning any specific brand) don’t! You end up having to use the compound to get the extra offset required to reach the centre line.
If you watch his channel, Curtis from cutting edge machine, just made a shop made boring bar. I don't remember the dementions but it requires his shop crane to move. 5 or 6 inches in diameter and several feet long.
Thanks so much.... I've been watching .. might miss a few but I'll go back and rehash them like my meds .... use as needed .. LOL😂😂😂 very boring video .... Please keep them up cuz I learn a lot..
Can you provide a video sometime on how to machine the inside of a cone? It seems like boring bars should work, but the clearances on small cones are problematic. Thanks for all the instruction!!

I used round saws for the same purpose. They probably don’t clear burrs as well but it is a cheap way to remove a lot of material.

❇️ ❇️I’ve never used a boring bar tool. My concern is the the largest Aluminum Rod Stock I will be using is only 3/4” OD for 90% of the Wheels or Sleeves needed. And the other 10% is only 1” OD Aluminum Rod stock.
❇️❇️❇️I luv those Index Cutting tools you Demo in your video, I purchased a set of 5 1/4” Index Holders complete with the Inserts 2 years ago for $20 on Amazon & they have been Performed Very well for every part I’ve made to date.
❓However I’m not sure of the {TYPE or SIZE} Boring Tools to purchase for the small 3/4” OD Aluminum Stock needed for these Sleeves…🤔
❓What type of Boring bar cutting tools would you recommend for this smaller than 3/4” ID Aluminum stock I’ll be using❓
Thanks again for an excellent video, your style of instruction is PERFECT for my ADHD 🧠.. I’m so glad that I stumbled into your YT channel & now FOLLOWING.

Could you do a video on cutting saddles in flat stock to perfectly mate the diameter of round stock? I made a keyed shaft and use a horizontal mill cutter the same diameter of the piece I want the flat stock to sit on. Then I made a jig for the tool post to hold my flat stock and feed it into the cutter with very shallow cuts. Very time consuming with two thou cuts. Gotta be a better way. Especially on an angled piece with anywhere between 30-60 minutes of angle.
Full or boring content. I liked it 😉
I just love this Channel
This vid was just in time. I'm working on a back plate for an uber sweet bison chuck i scored from a friend. "hashtag definitely sponsored" Anyway, need to bore the register for the spindle, literally came in to search vids for exciting tips and boring content... And this was sitting on my home page. Serendipity? why yes, yes Seren, it is dipity. Very dipity indeed.
I do appreciate a good dipity
A boring bar cuts only in one spot similar to a step drill. But the step drill has the advantage of having the opposite side of the cutter pushing against the inner face of the material. Could it be possible to make an insert that cuts on one side and the other side would be smooth and slide on the new freshly cut surface. That cutting tool would be on an pivot point and after each cut, the tool would have to be turned slightly to expand the radius. The bar would only move in and out along the length.
Thank you for this video it's good lesson for me,gretting from the Poland😁😛
I've in general have noticed that with boring and it's not just here, in other aspects of shop working like welding, one often never truely 'masters' an area of work. There's that imperfect element to it until the moment of retirement. Always room for improvement. So the term ' work in progress' is often the constant. Which not everyone seems to have that basic grip on. I only seem to bore maybe at best 3 times a year so trying to keep in mind the technical aspect and remembering it can at times be an enemy.
Gave it a thumbs up just for the opening pun.
Queen Quinn is here!
Your very good at explaining things!😁👍🏾
One thing to make sure of when flattening the bottom of a hole is that the cross slide actually has enough travel for the cutting edge of the boring bar to reach the centreline of the spindle. Believe it or not, some import lathes (not mentioning any specific brand) don’t! You end up having to use the compound to get the extra offset required to reach the centre line.
Someone should open a pub called the Boring Bar near like Hampton Roads or something where there's a large population of machinists.
Thank you for the clear instructional video.
I was waiting for this video to come out! So excited. 😊
The best way to bore a blind hole is . . . . “don’t do them”. LOL
Great video!!! Question……..What type of boring bar could I use to open up an 18mm hole to 24mm hole in 4140 steel material??? Thank you
Great job Quinn!
Many thanks that you share your knowledge with us. I wish the best!
Aww... I was expecting some sort of joke about the gargantuan boring bar that Cutting Edge Engineering Australia made a few weeks ago.
If you watch his channel, Curtis from cutting edge machine, just made a shop made boring bar. I don't remember the dementions but it requires his shop crane to move.
5 or 6 inches in diameter and several feet long.
😲
Thanks so much.... I've been watching .. might miss a few but I'll go back and rehash them like my meds .... use as needed .. LOL😂😂😂
very boring video .... Please keep them up cuz I learn a lot..
We all know you are more than a little eccentric, Quinn! LOL!😁😁😁😁😁
'Boring bars' even has an extra unintended pun for musicians!
Thank you for this most excellent video
Thanks Quin for great content again!
Can you provide a video sometime on how to machine the inside of a cone? It seems like boring bars should work, but the clearances on small cones are problematic. Thanks for all the instruction!!
