God Damn, I just bought a 8x16 lathe and looking to use it properly for fabrication and this ENTIRE PLAYLIST is an amazing reference to learn how to do the most fundamental operations. Excellent work!
I find your video clips so informative. Thanks for your teaching.
what a beginning....
You have such good communication skills.
I can learn from this. I’m a 75 year old geezer trying to occupy my retirement years. I was gifted with a Harbor Freight metal lathe and milling machine. I think I have zero aptitude for this, but I still have the interest. Your lessons fill in the gaps for me, making me believe that maybe I could do some of these operations too. Right now I want to machine a chisel-bit bushing for a Powermatic mortiser (I got some 1.5” aluminum stock). I need a .75” ID on this, and somebody said I should follow up the drilling with a a .75 reamer. Anyway, your teaching at least gives me the confidence to put something into the machine, remove the chuck key, and try to make it happen. Thanks.
Just started watching, and am enjoying it. I especially like it when teachers like you show failures, how they happened, and how to correct them. Bravo!
Keith Olson Thanks very much! I plan to do a lot more of this style of teaching, for sure.
I have to admit, your instructional videos are the best, regardless the subject type. The audio and video is as clear as any professional presentation, kudos to you!
That cat convinced me. Subscribed! Don't have a lathe yet but planning buying one and starting that hobby :) Very happy to have found your tutorials! Thanks :)
Sprocket firmly believes she’s the reason everyone watches.
@@Blondihacks Love the name! :D

I started watching your tutorials about the middle of last year. I had been curious about machine shop type work for a very long time, so it was a no brainer to watch ALL your tutorials to see what was involved. Last september I purchased a PM1022 which took 4 months to get here. I figured it would make it easier to apply the information in your videos plus if you use one of the PM lathes, they must be OK; You doing the quality control for me so to speak. It has been almost second nature getting started, thanks to your excellent instruction.
Each of your videos are well thought out, very articulate, with good quality video and audio, and I appreciate the lack of vulgarity. I have not encountered any problem yet that you have not already addressed in one of your lessons. Thank you very much for sharing what you know in such an excellent manor.
Sam
All I can say is Thank You. You are a gifted teacher. This is husband. I bought a lathe to repair my ammo equipment 10 years ago. No training, I just started chopping stuff. Now I know what Iv,e been doing wrong all this time. Just bought my second lathe and can't wait to apply what you taught me.
I've never been confident enough to get into machining, but now that I'm building lightsabers, I find myself learning really fun jewelry and watchmaking skills for small scale fabrication. Thank you for this Channel Quinn, your entire playlist is giving me the confidence to get into this!
your video brought me so much joy, your videos kinda give me elf vibes
Thank you so much for doing this series, having recently acquired a mini lathe and mill and being completely new, your clear and to the point instructions are super helpful.
That's great to here! You're going to love machining. It's a beautiful and delightful pursuit. When I was starting, I felt there was a "missing piece" on TH-cam of introductory videos that are short and information-dense. I hope this series fills the gap.
You are the Best! I’ve been watching many machining videos looking for the perfect beginner ones. Great teacher!
Thank you for the kind words and for watching! ☺️
This is one of the best tutorial series I’ve seen. So informative and to the point. Thank you so much for making these. On to the next one ✌🏼
Thanks Quinn - this series is a great resource for everybody who machines as a hobby
Great stuff. I have made huge progress thanks to you.
Thanks very much, i just acquired a small lathe last week and had the small nub left when facing, this helps a lot as do all your videos, Thanks for putting in all the hard work to make them.
Thank you for this series .. Recently acquired a little Hobbymat MD65, I am learning so much and trying to resist asking questions ... so many questions!! Brilliant.
This series is fantastic!
Your videos are absolutely amazing. Thank you SO MUCH for creating and sharing with the world. You give This Old Tony a run for his money :-D
great job teaching the skill
very informative, thanks for making these tutorials!
I work with lathes everyday at work, But always nice to go back to basics.
These are fantastic.
My Chinese 7 X 14 mini lathe is now sat on a solid wooden bench topped with a 2" thick slab of surplus kitchen work surface. Coincidentally the perfect width and length!. I think it's all reasonably solid. At least as solid as I'm likely to need as sub thou mm work is not what I'm looking for/needing.
However I've noticed one interesting thing: The one tool I have fitted to a standard holder (by the previous owner) has a piece of oily card under the tool and that how I tighten the fixing screws, and the order I tighten them, can make minor differences to the tool cutting height.Fortunately I have 2 sets of quick change posts, so it's not likely to see much use other than roughing passes until the carbide tip has worn out all the cutting points. It seems to be the only one he has ever used and even the first point still cuts quite adequately. At least in ally! For my first project I think I'll make your tap follower ... When I get to watching you making it again :)
Ta very glad for all the tips and pointers, old girl.
Wow...Very nice tutorial series👌
Really well done videos.
Very nice tutorials, great job.
Just got my first lathe setup, and must say I'm jealous of how easily you can turn your chuck by hand. I originally ordered a pm1127 that would have operated much like yours, but due to uncertainty in availability I "upgraded" to a 1236 which has the big clunky gearbox speed selection. That coupled with increased mass means I'm gonna have to beef up my forearms. 🙄
Thank you so much for your video and your skills , never used one before but i am thinking of buying one , as a mechanic by trades , i really need to get in to the metal lathe, keep up the good work
I imagine you have a scientific background ? You are so precise and detailed in your presentation ! Congratulations !
Thank you! Yes, my education is all in science and engineering.
@@Blondihacks Great ! Me too. I've started foundry one year ago, and my parts come out of foundry quite nicely now but they nevertheless need a little bit of lathe work to reach a perfect finish in some cases.
@@Blondihacks Science (why we can't do _this_ ) and engineering (hold my beer). lol
Another awesome video.
Great vids, great work. Thx!!
very well explained
Good stuff!
I don't know what all that subscribing stuff is on patreon and I'm not to computer savvy but I sure do know a good teacher and sorry you are a good teacher I enjoy your lessons very much.
Thank you for sharing the basic tutorial. I subscribe ur channel to update ur new videos.
Outstanding!!!!
Thanks
I just dropped in from Adam Booth's channel. Subbed and clicked the dinger. This is the kind of detail I need. Thank you
Thank you for the sub, and welcome! I'm glad to hear my videos are connecting with you.
no need for me to go back and paid $800 for another course, i can weld, panel beating, spray painting, grinding , engine rebuild, but never touch Lathe, now i'm confidence from your tutoring
Brilliant, informative and to the point videos with excellent narrative and delivery; I know how difficult that is, I used to teach..! Can I offer a advice on setting tool height I saw in a video elsewhere. Put a steel ruler against the side of the (round) work piece and offer up the tool to the ruler. If the tool is in line with the centre, the ruler will be vertical, if not, the ruler will be at an angle. Of course if the side of the work piece is too rough it will not work but otherwise it is fine.
just got my first lathe on the way grizzly G602
Excellent video. I'll keep watching to find out, but how do you mount the piece in the chuck to ensure it spins exactly along its centre axis?
Hi- We have the same Lathe!
In Australia We call the nubbin a Pip
Another way I was taught to center the tool is to pinch your scale(ruler) between the bit and the part, and adjust the tool until the scale is vertical.
Just one question remains how to fit the block square to the Chuck!! If primary reference is not close enough more materials will be wasted.
Sorry forgot to thank you.. and bombarded with questions... ❤❤❤+1, such teachers make me fall in love.
I can't wait 'til you get to knurling. I've never been able to understand how the knurling tools I've seen are able to put an integer number of knurled grooves in material, regardless of the circumference.
knurling is magic
I will be doing a video on knurling, but it will be a while, so I can spoil this one part- knurling tools actually can't do that. There is an ideal diameter for the tooth pitch of the tool, and the further you are from that, the more rectangular the pyramids of the knurl are. However, this is hard to notice, and combined with a general smooshing and overlapping of the points, the end result usually turns out okay. For a truly perfect knurl, however, you do have to turn the part to a common denominator of the ideal diameter. There are knurling calculators online where you can determine this.
Great video series!! I'm looking forward to parting. I can't count how many blades I have shattered.
Land Mark I’m looking forward to shooting that video! Parting is a real dark art, for sure.
Running in reverse and flipping blade to cut from the top works pretty well. There can be blade mounting issues to implement this. In this unconventional arrangement the scarf also falls away from the blade.
@@jerryquigg3497 I think you meant swarf.
chuck fischer Good catch - Correct.
hmm... I think using the tailstock to set tool height to center, would require having the tail stock properly aligned in the first place... is there a resource for setting up the tail stock?
This. Is. Goood
nice, do you have a video about the effect of css and sfpm on facing, I use cnc but practically i see no effect on the surface finish from both css and sfpm, mabe parting but not facing for me as far as the material is proper, if the material is garbage then non of css and sfpm can help also, in that case i dont see the point of css on facing, need your opinion on that
I’ve come a long way watching your videos THANKYOU!
I am at the point where I am looking at a new modern lathe, I want to go as big as I can afford so I don’t have to repeat the process later in life, my question is about tooling size, my current lathe from the 60’s doesn’t have quick change tool post so I can fit any size tooling in it, I generally use 8mm high speed steel, if the new lathe is designed for 16mm tooling do I have to buy all new tooling to suit or can the smaller tooling be used in the new larger lathe?
Is it possible to go too big and loose the ability to work on smaller work?
Quick question. What if you have a part that you have to cut close to the right length except leaving say 10 mm extra right away before you put it on the lathe and you have to true both ends and the outer surfac so that the ends exactly parallel to each other and the outer surface is perpendicular to the end? what should I do?
I'm following the series... but missing a step here: work holding. How tight should I turn it? Should I tighten all bolts on the chuck... etc.
Great questions! In general, just “good and tight” is enough. You don’t have to really crank down in it. Some people believe tightening all of the pinions on a scroll chuck helps. I don’t do that myself.
I got a 10x22 I'm muddling through it
Are there any models of small lathes that you would recommend for the first time hobbyist?
How to do face grooving using hss bit? I use chinese mini lathe, have tried cut in delrin, but now I need to make it for steel. Thee groove must be 10.8mm OD, 1.5mm wide and about 2mm depth.
My plan is making from old 10mm drill shank, but need more advice before I start grinding
👍
Hi, do you need to square the diak to the chuck face before facing?
I would really love to see a chunk of 304 in that lathe.
You had me at “nubbin”
What about if my lathe doesn’t have the lock carriage !! Am not shore if there is and I didn’t discover it yet!! Or it’s doesn’t?!
Hi Quinn, how do you know that the cylinder of brass is located parallel to the chuck jaws? I can see for a longer piece it would be, but for a short piece like that, is there some chance that the bar won’t be completely parallel to the ways, or does the chuck automatically straighten the workpiece?
Just watched episode 9, and have the answer! Tappy tap tap.
What is that Bosch "salad bowl" on the wall above the lathe?
That’s an electric car charger
Good very nice 🌷🌹🌷🌹👍🏼👍🏼💞💞
Hi .
What metal lathe do you use ? I mean make and model ?
So how do you raise the tool?
Where did you get your brass metal scriber?
I made it!
Why are the toolpost and tool at these weird angles? Wouldn't it be better to have both be parallel to the spindle?
Toolpost angle is used to get appropriate clearance angles. It does not affect the angle of the resulting cut
@@Blondihacks So at 5:00 it doesn't matter that the tool is at a 45-ish degree angle to the work? I would have expected it to be perpendicular.
❤️👍🏻👍🏻👍🏻
'Rubbin' & nubbin' - for when you REALLY love your work!
Got some bad nubbin. :-)
I hear both live center and dead center, I don’t think there’s a right one
I don't see this commented on, but at about 5:10 the audio becomes unsynchronized, and there is no voice over explaining the tool height issue for quite a while.
It’s just you. There’s nothing wrong with the video there
@@Blondihacks Interesting, I reloaded the video and it's all fine. Hadn't realized audio/video could go unsynced like that in the local player. Sorry for the false alarm. 😉
the only cutting machine that i did its a disc brakes and flywheel machinery no im next to the Lathe machine
Chandler Bing has a nubbin.
I want to kiss that cat so much,and ty for your tutorial 😍
Greetings! I have bee;watching your videos with fascination for a while now. One thing you don’t talk about is any form of recommendation for a decent affordable lathe for a starter. Something that would be not only affordable but something that a new machinist can grow into. If you don’t wish to play sponsorship games or deal with those concerns, you can IM me on Facebook if you wish. I appreciate your vast knowledge and the work you put into these videos.
