Cheers Max - excellent lesson in batch work. I learned a great deal here. I would have done too many ops at one time. Watching you it is very clear that fewer ops at a time is yhe way to go. Also very pleasing to hear the lathe referred to as a center lathe. That’s what I was taught. Stateside they call it engine lathe. I prefer center lathe.
Crumbs, you could make competitive paint drying watching sound exciting! I once had a holiday job inserting screws in switches, after 1.5million screws I still could not make the piece rate, but it made me realise if I didn’t get my self in gear, this was my lot!
Fitting was .my first then machining. But the fitting was rusted on nuts& bolts. A NZ bloke had a bolt breaker. But the missed hammering to thumb. Stopped me from being quick on the lathe. Could create a good run on the turret. But fingers need to be careful. Nice job shop run. Time is always what we're up against.
Nice process and procedure Max. Reminds me of back in the day running a #3 and #4 Warner Swasey Turret lathes, bar machines. Of course we did not single point the threads, we would have to tap. Have to do secondary operations on another machine of course. Anyway, nice work Max. Have a good weekend. 👍👍💯
Never heard of "Block" work Max, great demonstration of tool change versus part change to aid production time, any repetitive jobs always gives the mind a chance to improve , and earn more money in some case's 👍. I was on timed cards for a whilst an apprentice.
Well g'day Max, another fresh Saturday morning, hot coffee, moggy on me knee and here we go, there's my sticker perfectly in shot too 😂 thank you so much for sharing, this one is right up my street mate, best wishes to you and yours Ralfy
Thanks Dean . My ones are hard to disengage at anything other than slow speeds on that small lathe . South Bend got it right , nice to use on my little 10K . 👍
Well chalk & cheese mate!! You running that JFMT lathe looked like nighttime instrument flying in an aeroplane! Yeah, I noticed where you were engaging the half nut on that HAFCO in a previous video, and thought it was curious, thanks for the explanation. Those were some good techniques for running batch parts, always here to learn. One of the things that keeps me coming back! My shop teacher in high school tried to get across the importance of order of operations, but it didn't stick well with me then. Probably because I was too busy trying to figure out how to make me a smoking pipe for my herb (and yes Max, that's probably is what's wrong with me, too much cutting oil inhalation!). I did manage to create a right nice one, but wish I had paid better attention when he was trying to teach, but part of my attention was focused on dodging chuck keys, so I guess I have a bit of an excuse. Good video Max. I always enjoy when you get the bird song on the videos (usually at the beginning and\or the end of vides). I get to hear birds sing that we don't have here, very cool. Been a bird watcher \ listener since 4 grade. My teacher then was an ornithologist and a taxidermist and science class was almost exclusively birds, with some trees thrown in from time to time. Grateful for having such a great teacher. Lived near Lake Tahoe at the time too, so the forest there matched the curriculum nicely. Thanks again Max, as usual I'm grateful for the lessons.
@@swanvalleymachineshop actually it was mild steel, turned the bowl with a drill bit, then did a press fit with the stem pressed in the bowl, even had a swivel lid attached. It was a good design, I copied it from an existing make. I had a cool shop teacher, he said I did a good job, but because of what it was he gave me a C. Really messed up using cutting oil, took a while before that taste was gone. Wish I still had it even though I quit smoking about 6 or 7 years ago. It got confiscated about a year after I made it, and I never saw it again. But that's another story for another time.
Nice job Max, makes sense to use the JFMT to thread the nuts. I use pottasium nitrate, aka salt petre heated to liquid state on my gas burner and parts immersed for about 10 min to give a beautiful blue finish and preventing rust, adds a nice finish to the part.
Cheers Max. Try putting 2 nuts back to back in the mill vise and cut a slot through both. If you don't have a cutter the width of 2 slots, cut one forwards, move over Y and cut the other on the way back.
G'day Max. You said you were taught this method of 'Bock' turning many years ago. I bet that was probably worked out for " War time production". And I have a sneaking feeling it would have been for the First World War and not the second. I was astounded by the spindle speed of 720 rpm's when you were running those 3mm pitch threads which you managed in a conservative 14 passes! Boy that was quick! But you are a top manual machinist mate not doubt about that! Cheers from poor old England ( suffering under our new Marxist government lol)
G'day Max. Excellent Tutorial for a NUT Production Line. Threading is bit to fast for me, but, yours came out very well. Each to their own, & you certainly nailed that one 😊
Hi Max, Yep its Friday here too, no beer for me though, rush job in the morning. Fcuking arosholes, leave it to the last minute, wanted me to do a double shift, yeah right, said I. Ho-hum xmas is coming so the O/T will come in handy. Best wishes, Mal.
You get that on the big jobs ! Lol , i had one last Friday arvo come in . An M26 X 1.5 special plug for a hydraulic pump . The only option to get one was to buy a pump , ex Germany ! 👍
The threading at high spindle speeds goes nice and leaves a good finish, it must be nice to have multiple lathes, my DSG is metric but I don't have room in the workshop for another lathe. The DSG I have has automatic threading trips, but you have to remember to take your hand off the lever otherwise it doesn't trip out, but it makes threading to a shoulder easy.
Nicely done maxs the speed you was screwing them was impressive you’ve only just started using that lathe as well I’ve been using my m500 Harrison at work for about 5 years and wouldn’t of had the balls to go anywhere near that speed lol cheers max👍👍👍
I figured this out a long time ago. I would make several parts and be really annoyed at all the changes each time. It’s really a matter of sitting down and thinking about what you’re doing. Then it came to me.
Hi Max I enjoy your videos immencely. Did you consider tapping the M24 x 3 threads with a spiral flute machine tap in single pass. Down side is that a good quality YG1 tap will set you back about $100 and a 2 week wait. Up side is the tap will last a long time. Cheers
Think Max wanted to ensure the thread is absolutely true to the bore. I have tapped other ID threads before on extension shafts and they were never dead true when the shafts were assembled. But Max have had another reason. It is also the same when using a die on the OD of a tube/shaft. Using the lathe to cut threads is to ensure accurate alignment and fit up. My 2 cents worth anyway.
@@bobhudson6659 Thanks for your thoughts Bob. When Max had that many to do my mind just shifts to higher production. I find that alignment using a tap is not an issue on a lathe. The method I use is to hold the tap in a chuck on the tailstock. Don't use a normal tap holder. Manually drag the tailstock so that the tap engages with the job. Then use the lathe jog button on low speed (about 45RPM). Pull the tailstock into the job until the tap engages. Once engaged, the job will pull the tap/tailstock into the job. When the correct depth is reached, just reverse the lathe.
I would have tapped it in the lathe if i had a spiral flute or a gun tap . I only have a standard M24 hand tap & also there was not much of the part to get a good grip on . 👍
By the way, I was thinking that threading at that speed makes for better, sharper defined threads and less chance of the part migrating backwards in the 3 jaw chuck. I bet a six jaw chuck might be on your wish list. They seem to be a good thing to have, but I couldn't tell you for sure, as I've no experience with one. As for the threading speed, it made me think of a saying I've heard a few machinists say: Clearance is clearance!!
@@jefftheaussie2225 I believe you misspelled clearance there. Didn't think I would have to explain it but, in many cases in machining you deal with close tolerances, say where a part in the chuck barely misses hitting the carriage, or like when your threading at high speed and barely miss crashing into the chuck, so as some machinist say "clearance (no matter how small) is clearance! Hope that explains it for you. Cheers mate
Gidday Maxy. I am a dumbass but when cutting flats on the nuts could you not put 2 or 3 in vice at once and run them through? Thanks for your vids cobber.
Doesn't getting your setup and system of work right, make a big difference to how quickly the job goes. And being able to cut the threads at higher speeds seemed to make a difference to how well those threads cut as well. I keep meaning to try Joe Pies way of reverse threading, but when it's only a small one off I cannot be bothered to reset my tooling. Really must do it.
I still have to buy an M24 x 3 spiral flute tap or a gun tap ! And apart from not much of the part to grip the part on , would be a big ask for my standard M24 tap & not have the part slip in the chuck . 👍
Jesus mate, boring the tapsize hole, single point threading, seperate op for chamfer... just drill, run in a tap, chamfer with a cordless... nice procedures on multiples tho...

As apprentices at BP we did it that way, by the way potassium nitrate is ideal for stump removal.

I learned something, good episode. I'd be interested in seeing the machining of the soft jaws😀?
No worries . I have shown it in an early video , short run production from memory a couple of years back . Cheers 👍
I figured this out a long time ago. I would make several parts and be really annoyed at all the changes each time. It’s really a matter of sitting down and thinking about what you’re doing. Then it came to me.

Max,
Why didn’t you use the Tap for threading in a production run…?
Did I miss something..?
Don't have a machine tap & not enough of the part to grip on to use the hand tap that i have . 👍

Center or spot drill, that is my question
Use either . I stick with centre drills in the lathe & spot drills for the mill . 👍
Why didn’t you just tap the threads Max?
I think the cost of a tap will make your eyes water .tooling is expensive in Australia roughly double the US price
Yep circa $100USD for a reasonable branded 24mm 'single' Intermediate Tap. Used options are there but not where I would want to go.
I still have to buy an M24 x 3 spiral flute tap or a gun tap ! And apart from not much of the part to grip the part on , would be a big ask for my standard M24 tap & not have the part slip in the chuck . 👍

Another trick for the tool chest! Thanks Maxi!

Gotta ask... why would you NOT cut threads with Tap....would that not be quicker...?
Quicker if i had a spiral flute or a gun nose machine tap and more of the part to get a good grip on in the chuck ! Cheers 👍
