How to cut threads

[@R_-_F]

Hey Fireball, Nicely done buddy. You will appreciate our new shop motto: “We may be slow, but we do crappy work!” Take care

[@Toolmaker001]

Nice...

[@Toolmaker001]

After I washed my hands I worked the thread off camera a little bit once I was able to grip it. Didn’t take much and it polished right in with oil.

[@RichFife]

Seemed A little tight... until you worked the threads. How much did you remove, around .002"? For threads that need to be silky smooth without slop, I like using the 3 wire method. Sadly enough, I don't know too many people that do the 3 wire method. If anything, it's always good practice. Depending on the threads being cut, I'll either do the straight depth method (cross-slide) or the slant depth method (compound). If I'm looking to run some v-sharp threads fast... I'll use the compound rest and dials with the compound set at 29-1/2* Days where I don't feel like coming back to a dedicated start point, I'll run straight depth. 😅

[@Toolmaker001]

Only used oil and put my loops on and removed some small slivers. It polished up in a few minutes.

[@DavidHerscher]

That gearhead is so smooth and quiet. My 15x72 leblond absolutely screams at anything above 600rpm. You definitely can't talk over it comfortably lol.

[@Toolmaker001]

Yeah, it's not a bad lathe for a $5,000.00 price point.

[@Toolmaker001]

But it’s a Leblon

[@RichFife]

In the service we had a Leblond manual lathe, older model... that little lathe was so accurate and smooth... I used to cut Submarine valve seats on it. Nobody used it much because it was so little... (compared to the other lathes that we had in the shop).

[@DavidHerscher]

@@RichFife I also have a little 10" regal, probably really similar to the machine you're talking about since leblond didn't make smaller machines for very long. It's a gearhead, with a feed rod, and reversible feeds in the apron. All incredible features to have on a 10" lathe. It has all the features that are normally reserved for larger swing machines, packed into a tiny little 10" package. Very cool machine, and pretty rare as I understand as well.

great video once again

[@Toolmaker001]

Thank you so much Kal.

[@kimber1958]

nicely done

[@Toolmaker001]

Thank you

[@Toolmaker001]

I did have to work the thread a little after I washed my hands. But it came right in quickly.

[@dermotkelly2971]

Thanks for the info about screw-cutting. Ever since I was a teenager I was always taught to feed in with the compound slide

[@Toolmaker001]

I might do a video on this compound myth.

Amazing stuff greetings from Argentina Jeff :))

[@Toolmaker001]

Thank you very much. Argentina how cool is that.

[@larrymatsumoto7730]

Excellent video, Thanks Jeff best threading video I've seen 👍

[@Toolmaker001]

Thank you Larry.

[@kimber1958]

thank you brother

[@Toolmaker001]

Absolutely

[@patrickboyd7753]

Good job

[@Toolmaker001]

thank you

[@misterlewgee8874]

The second video of yours I've watched. I'm intrigued about "catching" the thread...I like your description of the panel pitch chart...good to see the wheel which indicates when to start the run... I still don't know if you manually start the run in..visually looking at the 1, that would make it tricky I guess...

[@Toolmaker001]

I have plenty of threading videos on my channel. Go check them out.

[@misterlewgee8874]

@@Toolmaker001 im slowly watching them...saw you manually hit the "start stop" handle... Thanks. Enjoying. Thanks. Sam.

[@liukang81]

You do good job sir! I like your lathe! Could you provide me a link or website where to get the lathe like yours, please sir!? Thank you very much!

[@Toolmaker001]

Precision Mathews. Thank you

[@reaper060670]

Hello there. Just found your channel this morning at 6am. I love the Lathe u have there. It looks like a real proper built machine. I see u also have the Mill too in your shop. I want to buy a Lathe but the cost is too much. I've been thinking about buying one of those cheap Lathes from VEVOR/China but I'm seeing more and more videos telling me not to get them bcos they're for the most part badly made. Could I ask a question about your Lathe if u have a minute please?? How much would one of your Lathes set me back? What is the price bracket I would find myself shopping in and would u suggest a slightly cheaper option for my 1st Lathe if possible please? Thanks of r a brilliant tutorial man. It was very enlightening concerning the numbers and how important the DRO is in these circumstances as well.. Take care with your illness too btw and I hope u get well soon my bro..

[@Toolmaker001]

I believe the lathe I bought is around 5500.00. PM does offer a few smaller lathes but I have no experience with them. go on the website and check them out.

[@reaper060670]

@@Toolmaker001 thanks man. Appreciate the reply very much. I was going to have a look so thanks for that. It's a really nice lathe u have man..

[@dperfetti1]

Jeff, it looked like that thread was very tight at first. ?

[@Toolmaker001]

It was a lil tight. After I came out when I washed my hands i had a better grip and I worked on and off a couple times and it cleaned right up. Did it with oil. This is a very common practice for me when cutting tight engaging threads.

[@dperfetti1]

Jeff, I've cut close tolerance threads in aluminum before myself, and I know what you mean. lol Great video.

[@Toolmaker001]

I do a lot of fine threads in aluminum, and this is the norm for close engagement aluminum threading. I'm sure you know this.

[@Toolmaker001]

As well thank you.

[@gardnep]

Just failed to cut a 3/4”x10 thread on hard steel. Aluminium is a lot easier. I might try 500 rpm. Same lathe.

[@Toolmaker001]

What kind of steel are threading?

[@Sweetchilliheat18]

Yes man, beautiful threads But how much material can she hogg Serious question That's all that really matters How will it hold up against a 316 forgeing say 6" od x 6"lg Or welds My gear head will be here in july, I went with the king. STM chucks are on sale at SOWA, obviously the two machines are different bit how big can I go, am I okay with a 10" 3 jaw, like would you run a 10"?

[@Toolmaker001]

That would be something I wouldn’t want to do at all.

[@Sweetchilliheat18]

@@Toolmaker001 would it be possible for you to show some of the limits of what your comfortable pushing your machine to do? Was that a no go on the 10" chuck or just the 316 slug I run a 60" chuck vertical Bullard, 18" ID split bearing housings are my bread & butter ( I have no frame of reference on a machine this small)

[@Toolmaker001]

Well I’ve pushed it a few times and where this machine starts to show weakness (aluminum 6061 as reference) is bigger radius inserts cutting over .060 on diameter. It will do much better facing but still you start getting over 5 inches in diameter you will see some protest starting to develop on outer circumference. I’ve turned a lot of 304 and some 316 with it and it has some balls for sure as well has weakness in certain areas. Over all a very strong little machine. I’m easy on it so I haven’t even wanted to search for the edge of the envelope.

[@Toolmaker001]

It’s been many years since turning on giant lathes. And in the tool and die aerospace company’s I’ve worked for we did tons of tool steals and alloys. The amount of inconel and titanium I’ve worked is staggering.

[@Toolmaker001]

Yes, I’d say no go on a 10 chuck. It will do it but I bet it’s noticeable.

[@deb3663]

I know this is an older video, but you tube just suggested you to me. I noticed you have a lump on your right shoulder. May I please ask if doctors have ever said that it has anything to do with your breathing? Is your roommate ght side better than your left. My husband has the same lump on the same side. And his left lung has all the nodes it it. He is stage 4 COPD. Thank you will pray for you

[@Toolmaker001]

That is from a racing crash. Broke both shoulders.
