*Excellent lathe **MyBest.Tools** I started turning pens, and this is a very smooth running lathe. I am glad that I went with a variable speed lathe. It is made of top quality materials and will probably out last me. I highly recommend.*

[@victorbarroscoch]

The lever on the side is for power feed, the other engages the half nuts for threading.

[@qshed]

And if you change the gearing in the cover on the left you can get different feed rates

[@didndido3638]

A craftsman going out of his comfort zone to gain new skills?! Thumbs up from me!

What a coincidence! Matt and This Old Tony are my two favourite sources for KZbin crafting wisdom & fun. A collab would be darn cool 😎

[@argh02]

@Arno Hartmann @Matt Estlea hell yes! And add @Abom79 into the mix too - and if you want CNC prototyping, Matt's got to contact @AvE ;-)

OMG ! same here !! it's almost like we all have been led from viewing one channel to be presented the other channel by some kind of invisible hand !!!! What ? That's exactly the case ? That's actually what youtube algorithme is all about ? Ho ok =(

[@MrHabart]

@@argh02 I found AvE by accident, he led me to This Old Tony, then I got into woodworking videos to get some ideas for some furniture I'm building and found Matt. Gotta love KZbin

[@ET-cj8jo]

As others have already commented, the rh side lever is for power feed and power cross feed. It uses a worm gear that surrounds and slides along the leadscrew but powered through a woodruff in a keyed slot along the leadscrew, so it doesn't use the leadscrew thread itself (and that prevents premature wear which might cause poor thread-making). The front lever engages the half nuts to the leadscrew for thread cutting, and the speed of that relative to chuck speed is adjusted by gears on the left of the lathe. It is of course quite possible to adjust the power feed by changing the speed of the leadscrew through different gear ratios, as you would for different thread pitches. Note that the SC4 has a chuck disengage (the large silvery knob on the rh bottom of the panel) to stop the chuck spinning when using the mill attachment and power feed.

[@davearrow3]

Hi Matt to work out rpm use this formula Stainless steel 23-40 meters per minute so 30 x 318 =9540 then divide by diameter 10mm =954 RPM So for RMP it is MPM x 318/Dia easy👍

[@Ashe_Fenrir]

Very cool - excited to see all the metalworking. I'm going to try and make a mallet.

[@SkylersRants]

I love it. Thanks for trying new stuff in front of us.

[@PatrikGerenmark]

That was really interesting to watch. All other metal working channels I've watched speed up the actual cutting. Fun to watch you learn the craft. I hope that there will be more of these videos. Keep up the good work!

[@stephenjimenez9539]

I've always wanted to learn metal turning. I find it so cool.

[@rascalholden]

I'm interested in anything to do with working with my hands and making things, scientific stuff and all that of it so am more than happy to watch anything you throw at us Matt. Keep up the good work mate I don't subscribe to many on you tube but you've got me in the bag dude 😎💪

[@NickWhite630]

I really like the metal working videos. I am probably more into metal working that woodworking but have minimal experience. It's very interesting to see someone who is learning to get an idea of how hard some things really are. I watch all of ThisoldTony's videos but like most with experience, he makes everything look so easy and now I see that maybe it isn't that easy after all.

[@bertv1205]

That is a 2200 bucks bit of kit, mate… Your employee discount must be really great. (Just jealous…)

[@stevenjones1009]

Yes unicorn pen on unicorn day it's like you planed it or something lol👍👍

[@dr1verman]

Made me smile, yes you have to learn. A good start is to have your tools on centre height.

[@danfall8233]

9:23... Aghhhh! BACKLASH! Backlash is a thing Matt! Nice to see you branching out though dude =) One piece of advice: set some stops so you can't acidently powerfeed into the chuck. Can't tell you how many times that saved me as an apprentice!

[@daviddunbar5754]

Ok not going to give you an abject lesson on centre lathes but just a few things about names. The bit that goes from left to right on the bed is the saddle or carriage. The bit that goes from front to back is the cross slide. The small slide on the top with the tool post is, not surprisingly the top slide. To cut correct threads you will need to change the gears on the left side of the headstock( the bit with the chuck and drive controls). The two feeds for the saddle are just course and fine for finish reasons. I didn't see a thread dial indicator on the saddle but then I might have missed it, needed for cutting screw threads. Well done for branching out, more power to your elbow. Should be interesting when you hit the milling machine! Keep up the great videos.

[@SquareTheBagel]

Matt, I was soooooo excited that you were going to be doing for some metal turning... But I had to watch through my fingers because lots of learning to do 😅

[@dr1verman]

Hope you are settling in with your machine now. 2 tips, where possible, try to make your finish cut 1mm deep, and don't let your tool dwell on the work without cutting.

[@MikeBramm]

Great job. We all have to start somewhere.

[@negotiableaffections]

This Old Tony is amazing. Smart and funny in equal measure, a favourite KZbin Channel of mine. You have to return the favour Matt and link this video of your 'prototype' to him. I think it will amuse him... [or he might just fly in and confiscate your lathe]. Better luck next time, this is a highly skilled occupation that my father did as his profession, and the learning curve is long and steep. I think you did better than average for a first timer. Nil Desperandum

[@applebutter4036]

This seems like a smart move(albeit expensive). Woodworking has it's limitations when it comes to making things. You have to keep expanding those skills

[@k.hussain360]

Good first effort especially showing it KZbin. I'm a mechanical engineering student and we've done some lathe work and I was fortunate enough to have an instructor guiding my hand. It's all about practice. There are some tables out there on speeds and feeds that will make the calculations a little easier. Off the top of my head I can't think what they are. I'll have a look at my notes and drop you message.

[@ThadySenior]

Colab with Colin Furze to teach you metal fabrication? Or with This Old Tony? That would be fab!

[@MattEstlea]

Need to get on their radars first!

[@normanboyes4983]

If you look at the two layshafts at the front of the apron - the slow feed is provided by the feed shaft. When cutting threads the movement is provided by the leadscrew (which is normally an acme thread). Changing the gear ratios for each required thread can be challenging - depending on the lathe. However incremental change is normally by levers on the front below the headstock and range changes by mounting and dismounting gears at the free end.

[@paulbrooks583]

Matt not sure if you set the tool to the right height at the beginning. The little nipple on the end of the workpiece after you faced it off looks like the tool was a little below centre. Might need some thin shims to raise the tool a little.

[@Dionysus4776]

Please send your former math teacher a link to this video, if she is still teaching. If nothing else at will probably bring a smile to her face, but she might use it as tool in class.

[@bttModeler]

I like to learn metal turning too! Have a small Proxxon lathe at home, bought it a year ago. Don't know how did I live without it 😄 Maybe you know this already, but pieces which length is more than 2-3 diameters should be supported with a tailstock. And also when changing tools you don't need to remove the previous one every time, just rotate the toolpost. Good luck, Matt!

[@RyRch]

Joe Pi is the Jedi Master for lathe-work - and any kind of machinist. He’s a massively experienced professional machinist, not a hobbyist.

[@markfullerton3130]

The faster feed will be for threading .ie. 1mm pitch. the finer one is feed. Hope this helps. Great video btw.

[@The13jamie]

I am liking just for saying This Old Tony, matt and tony are just the best, please do something together !!!!!!!!

[@turkey1605]

Hi Matt, I've taken up woodworking as a hobby recently, and been watching lots of your videos - hopefully this comment is (in some small way) going to be give something back :) I worked on manual metalworking lathes as part of my apprenticeship about 10 years ago. Here are some pointers which you might find helpful: 1. Set the cutting tool tip directly on the spindle centre line. Start by taking very light cuts across the end of the metal bar. The tool is on centre line when you cut right across the end without leaving a 'pip'. I think a pip is visible in your video at about 11:00 and 13:20. An on-centre tool can also give a better surface finish 2. Once you've faced-off, set the dial of the lower-left black handle to zero. This will then be your reference for all Z movements. Also set the dial of the cross slide handle to zero (you've got your hand on it at 13:48) 3. Take light skims along the length of the workpiece until the surface is cleaned up. When the surface is clean all round, measure using a micrometer and set the last handle's dial appropriately. This is then your reference for X movements. 4. Take another small cut to determine whether the dial is printed in radius or diameter units. For example, aim to take off 0.1mm, take a cut, then measure with a micrometer - if the part has been made 0.2mm smaller, then your dial is probably measured on the radius, and this will need to be taken into consideration for all subsequent readings. This could be the cause of the dodgy dimension at 10:30! Some other general information: - You mentioned backlash. I always found that approaching dimensions from the same 'side' every time helped. If you overshoot on the dial when lining up for a cut, don't just twitch it back to the correct reading. Instead, back the handle off at least one whole revolution and try again. - Spray some WD40 on the workpiece before each pass - this can help with surface finish. - To reduce flex when machining longer workpieces, consider putting a dead or running centre in the tailstock. - A bed stop and a set of ground slips can be used to make sure the saddle can be wound to a known Z position - useful for the 6mm bit of this workpiece! - If you lose your position on one of the dials, wet some paper and stick to to the workpiece. Start up the machine and slowly move the tool into the paper until it's flicked away. Paper is about 0.1mm thick, so set the dial 0.1mm too large and it should be pretty close.

[@ensen89]

Maybe time for a new series machining monday? :D 380 rpm seems slow for a piece that small, but the machine isn't that strong and you better be safe than sorry. You'll figure it out. Some lathe show the movement of radius on the dial and some show diameter. That can confuse even experienced machinists when they change between machines. What do you think about a dro for easter? :D

Hey, I've been considering buying myself a lathe recently to make some bits and bobs and came across your vid, it's occured to me recently that you can learn not just from pros but also those just starting out too especially as we all make mistakes when we start a new venture so I figured watch vids from those starting out and learn from the comments about their mistakes etc Anyway, part way through I thought hmmmmm I'm sure I recognise this guy but didn't think much more of it but now having read your profile I've discovered we live in the same place so I probably have seen you 🤣😂 Anyway, was off topic but hey 😂🤣 great quality vid btw, thanks for posting!!

[@howiebalch8402]

The faster feed rate might be related to threading. Nice rig!

[@franticdj]

Looks like it, you can see the thread cutting symbol at the lever.

[@neil1150]

Simple rules for simple machining. Feeds & Speeds, if it sounds right it is right. Screw cutting for dummies with slow reflexes. After machining the relief, (next time use the parting tool, its way easier.) Then put threading tool in place, but upside down, set lathe direction to backwards (top away from you) Then start the thread in the relief and cut towards the right side, take you time, no crashes as it matter not how far you go :) Plenty of time to engage the thread cutting on the odds or evens as needed.

[@klaastuik1437]

What brand and model number does the lathe have?

[@steventhompson3507]

You really dont need to worry at this stage about the rpm you can learn through watching your surface finnish and listening to the sound.

[@jeffdutton1910]

it has been a very long time since I did anything with a metal lathe, but my recollection is that one of those drives along the length of the bed should remain engaged so that on each successive pass the tool runs precisely in the previous cut. I can't remember if I backed off the tool and reversed the lathe to move it back to start each pass, or if there was some other way of sync'ing the tool position to the previous pass. Surely there should be something in the manual...or maybe this would be helpful: smithy.com/machining-handbook/chapter-3/page/24

[@mathewanderson2400]

I applaud exploring your boundaries and expanding your comfort zone. That said, I don’t get the same rush from metal lathe work - it seems slow and was not as fun to watch

[@SquareTheBagel]

Fast is likely to be for roughing (or threading) and slow for finishing

[@Caffeine.And.Carvings]

I always wondered, can you do wood turning on a metal lathe? It's much safer and easier than a normal lathe, and blades that cut metal should cut wood I assume

[@daviddunbar5754]

Yes you can but sometimes the wood is not so good for the precision slideways and bearings of a metal tuning lathe.

[@larsehnbom5384]

I like the Old Tony but i can recommend Joe Pieczynski as well for metalwork. He has lots of tips and tricks. The one for making threads are the best ever.

[@richbuege6491]

Hint for all beginning lathe owners. Read and understand the blooming manual, it will prevent problems and future bloodshed.

[@Julkio81]

"I don't want to tell you too much about it (so I am going to talk non-stop for ten minutes)" - Matt Stlea 😂. Anyway the episode might not have been exciting, but it was hilarious. Also it is good for you and for your channel to expand and do new things, a channel just for making dove tails would be a bit monotonous. I think the metal work is a great idea and can complement nicely your woodwork.

[@livingwithfshd]

Well said, this video was very funny and how your venturing into metal work is very cool. Keep expanding

[@crazy-eyewoodguy4489]

On your lathe you will need to set it to 59.5 * for threading You scale is different. Sorry if someone already said this, I Wasn't willing to go through all the comments.

[@dibblethwaite]

Pi is 3 for that sort of calculation.

[@ianknight7165]

I believe the two different feed rates are to do with threading, slow speed = fine/ tight thread, faster = course/ spread out thread. Please correct me if I'm wrong :) cheers

[@AlBorland3877]

What i suppose is, that the fine feed rate is made for reducing the diameter of a workpiece and the course feed rate is made for cutting threads.

[@Crushwokery]

Mat get yourself a zeus book. Your best friend for a lot of metal references. What you're trying here is like me trying to climb Everest and I'm 59 and over weight. Just trying to give perspective. There's a mountain of knowledge to learn but you'll get there with a lot if fun and an overflowing scrap bin on the journey. When I was 16, there were things called apprenticeships. Just for shits n giggles and young folk these were employer based skills programs where you were employed as a trainee, you were paid by the employer to go to college either on day or block release to learn turning/ engineering in this case and the rest of the time you were given to a skilled man to learn on the job. The duration of the average apprenticeship was between 3 & 5 years. Have fun, keep your fingers well n truly out of the way, never ever wear anything dangly and tie your hair back or wear a hat. Have fun & good luck you'll get there 👍😉👌✌️

It seems this old tony is a youtuber's youtuber. Your not the first to reference his videos. Which I love by the way.

[@anthonysalisbury6945]

The handle engages on the leadscrew.....not knowing the lathe there should be some gears or dia to change the feed on the leadscrew.....you can then use this to set the feed for cutting screw threads......you might be a way of doing that.....also if you put a dead centre in the tail stock you can use it to set your tool height correctly....the point of the cutting tool should be on centre. Also dependant on how the dials are setup you are cutting radius....therefore 0.2mm will take 0.4mm off diameters

[@chewychew3818]

Answer to the question. Ones for turning ones for threading

[@rentregagnant]

[@johndoe920]

you probably got the diameters wrong because you thought in diameter. The movement on the lathe is always direct movement, so the radius you're taking off, not the diameter. You apparently always took off twice the amount you wanted ;)

Watch closely at 15:10 That cutting tool clearly moved when you butted up against the existing shoulder. I think that should not happen. Either you did not fasten it well or the machine is crap.

You will need to watch Abom79 - Adam Booth, Keith Rucker (Vintage Machinery), mrpete222 (Tubalcain - Lyle Peterson ), and others who do more teaching than Tony .. LOVE Tony but he doesn't actually do as much turning/teaching. In fact there is one teaching on a machine your size but I can't remember off hand who that is. He is Aussie. In all cases, you'll need to search their vids to get the best examples. Good Luck.
