Hi Max, you truly are the best Australian machinist on KZbin. Keep up the good work. A lot can be learned from you.

[@swanvalleymachineshop]

Cheers Josh . I am enjoying watching the work you are doing on your old dragline . 👍

[@paulstanley9139]

Hi Max, when I cut threads either single point or with a die I use a file to dress it up a bit same as you. Then give the thread a good rub with a wire brush while spinning in the lathe. It smoothes the thread to full depth & gives a nice appearance. I never see anyone on KZbin doing this.

[@swanvalleymachineshop]

Good tip . Cheers 👍

Excellent job max, great video, keep'um coming..

[@bostedtap8399]

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.

[@swanvalleymachineshop]

It's also a good method to hold a reasonable tolerance on worn machines . Cheers 👍

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!

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.

[@swanvalleymachineshop]

No worries 👍

[@tas32engineering]

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.

[@swanvalleymachineshop]

Cheers 👍

[@JoeSmith-wd8ks]

Good work Max , you’re a great experienced machinist. I tried Joe's upside down threading recently for my very first attempt at thread cutting on the lathe . I was making a boring bar for my shaper and wanted to cut 2” unf . Tried my best at grinding a tool , it worked but I would not say it was perfect . Was dead scared of messing up the mesh on the lead screw ,( 2 tpi on an old Mitchel) , I always engaged at the same number on the dial . Anyway it fitted nicely. I noticed that you just seemed to engage the lead screw , I guess I could have as well ? Hey thanks for sharing your work with us . If I come to WA I’ll try to come by your shop and say gydday , cheers mate from New Zealand 👍

[@swanvalleymachineshop]

No worries . You would have to be careful of the side clearance angles cutting the thread that way . Cheers 👍

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. 👍👍💯

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.

[@swanvalleymachineshop]

Nice . I have not heard of that method before . I might have to look into it as i have quite a bit of bluing for the DSG to do . 👍

[@ericpatterson3887]

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]

Cheers Eric . Sounds like you had to do a bit of profile turning with brass !!! 👍

[@ericpatterson3887]

@@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.

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.

[@swanvalleymachineshop]

An auto threading trip would be a nice option to have . Cheers 👍

[@swanvalleymachineshop]

I like Harrison lathes , especially the 1965 L17 . Spent quite a few years using that model . 👍

[@melgross]

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.

It can be a good method to make good parts in a clapped out old machine ! Cheers 👍

[@nigelallen1500]

I have almost the same lathe in the UK, a 2007 year badged as a Gate 330E, with slight differences. Unfortunately it definitely does have the same half nut setup, which grabs in quickly sometimes, and difficult to release under load. As a self taught amateur, I thought it was just me! Otherwise, a great little machine.

[@swanvalleymachineshop]

No worries . They take a bit of getting used to , just thread in a slow speed . 👍

[@donsipes]

[@warrenjones744]

I have essentially the same lathe as the Hafco. probably made in the same place in Taiwan, but with a different name and features. Has an American style carriage wit the same shitty threading dial. The half nut engagement is indeed horrible. However it makes decent parts and gets the job done. Great technique you show here Max. Cheers

[@swanvalleymachineshop]

I think there may be quite a few made in the same factory . Different brands , same or similar machine . I think whoever the machine is branded for may reflect the quality , like the parts just out of tolerance go to the brand that pays less ! 👍

[@DudleyToolwright]

Those were some really interesting mass production techniques. Do you find that the thread smoothness improves with faster RPM? I seem to think that's true, anecdotally anyways. Thanks for the lesson, Max.

[@swanvalleymachineshop]

Yes , quite often the finish improves with a higher cutting speed . Cheers Rob 👍

[@samrodian919]

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)

[@johnspathonis1078]

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

[@bobhudson6659]

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.

[@johnspathonis1078]

@@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.

[@swanvalleymachineshop]

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 . 👍

[@kenmatheson5794]

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.

[@swanvalleymachineshop]

2 would be the maximum , the vice would not grip a 3rd properly . Then there is a lot of extra winding the table ! 👍

[@swanvalleymachineshop]

They are hard to buy . H&F no longer stock them for Gator chucks . Special order . 👍

[@ericpatterson3887]

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!!

[@swanvalleymachineshop]

You tend to get a better finish cutting quicker . A big 6 jaw would decimate my bank account ! Cheers 👍

[@jefftheaussie2225]

How’s the clearance Clarence?

[@ericpatterson3887]

@@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

Hi Max. Mate im not a machinist by trade as youll gather by my question . .... And wont be offended if you cant be bothered replying 😂. I do have a lathe, but considering upgrading to the same as yours. The alternative is the al336 chinese lathe. I went into h&f and really could tell the difference in quality just by the smootheness of the wheels (ie 960b felt waaay better). I know i dont need a foot break or even a dro. My question is, are the speed ranges sufficient? It looks like youve had your 960b for years, is it a good choice in your opinion? This will be my last forever lathe. Just using it for hobby work so is a luxury but i like being accurate in what i make. Clearly with the right operator the 960b can be 😊. Thanks so much, cheers steve

[@swanvalleymachineshop]

Avoid the smaller Chinese machines . The AL960B is reasonable , made in Taiwan but still made to a budget . My one has always had noisy headstock gears . In all honestly , i would look at what the dealers like ESP Machinery , Newmac and Machines 4 you have first . They sometimes have European ex Tafe machines . 👍

[@billdoodson4232]

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.
