TAPPING an ACME BALL NUT

"there are many ways of doing things" you are absolutely correct Mr. Pete. In my shop there are three ways of doing things. The Right Way, The Wrong Way, and My Way. Which method I choose depends of the project at hand. Sometimes I'll do it the right way, sometimes I'll do it the wrong way, but in most cases I'll do it "my way"

[@mrpete222]

Lyle's way. Professor Petes way. And of course,... You guessed it, Tubal Cains' Way.

[@keithpattison6763]

Hello Lyle, some years ago, I made a new bronze cross slide nut for my Hercus lathe(Southbend clone). I cast up the nut and as the thread was 7/16, it was too small to successfully screw cut. To buy a 7/16' left hand 10tpi acme tap was out of the question, so I made one out of some tool steel, milled the flutes, then hand finished the cutting clearances. When heat treating, it developed a slight bend, even after plunging straight down into oil. Still worked OK. I then screw cut a new cross slide screw to fit the new nut.

[@ellieprice363]

This video is “right up my alley” as we say down south. I have a customer who refurbishes dental equipment to new condition. One job requires replacing worn Delrin nuts in ball threaded ACME lifting screws. So far I’ve made new nuts with 3/4-6 single lead, 3/4-6 double lead, 3/4-8 double lead, and soon to be 20mm double lead. (two threads on one shaft). The customer furnishes the very expensive tandem ACME taps and I do the work in my home shop. Delrin nuts are self lubricating and very quiet and the ball screws usually don’t require replacement. It’s been interesting to learn how ACME taps are made.

[@mrpete222]

Thank you for that interesting comment

There is always many ways to do things for sure. Appreciate you sharing this with us. Thanks Lyle.

[@brentandrade5861]

I made one handled pieces like that, first I tried cutting the internal threads w a single point ground from drill stock. Challenging indeed! I too used rough cast old stuff found along the way.. bought the taps for 3/8, 7/17, and 1/2 acme. Larger left hand thread. For rebuilding my sb lathe cross slide.. but the single handles were to repair my antique Bridgeport mill. The locks r single handle. Having the tap is such a benefit! Holding such shapes indeed requires sum inventiveness! I used an old c clamp screw like you . 5 hours of sweat equity n my mill has all its locking handles in order. Thank you for such well done clear videos. Please keep up the good works. Oh, I'm now looking for a bench grinder / sharpening lap... 😢

[@StanErvin-yo9vl]

7/17 ? Or do you mean 7/16 ?

[@peterfox2565]

I used a un-machined handle like that to make a speed handle for my milling vise. I held it upright in my mill with a couple of v-blocks and drilled/bored it to a press fit for a 5/8" deep socket. I also milled a flat spot on the top of one of the ball ends to mount a small spinner handle.

[@paulhunt598]

Thanks for using the adjustable wrench backwards if only to spite the life long training that I have yielded to that they are directional. This has recently been a hot KZbin controversy. I have some quality adjustable wrenches even marked in the casting by the manufacturer indicating the correct use direction. I will have to go the the shops to confirm the brand(s). I have often used my adjustable wrenches backwards, but seldom without the internal fear that Dad or an early mentor is watching me, though they are all now dead. Even though a lot of data confirms that direction is not a significant deal, I still can't force myself to really load an adjustable wrench in the wrong direction. Howee's has recently demonstrated on KZbin that a lathe can't throw a chuck key as violently as most of us were taught, but I still can't make myself leave any key in a chuck. I have seen workpiece damage when the workpiece was thrown from a lathe. The bad ones happened in my workplace shop, but not by me. My personal events have been limited to the learning curve on the wood lathe. They were serious enough to elevate my caution and alter my approaches in the machine shop. You admitted that the desirable runout in your demonstration might have been mitigated by an alternative method. I find that one off processes teach you a better way after you have made an unintentional error or caused an unexpected event. Salvaging your only stock or workpiece then becomes a new challenge. I recently made a custom part for a friend and a small oops in the lathe bent the workpiece. I had no more suitable stock. I was able to recover and true and square the critical parts of the workpiece. It left runout in a non critical shoulder OD. Sending the work back including the the runout error irked me, but time and lack of material were critical factors and it went to my friend with an explanation and an apology. A paid job would demand rework. I learned from my oops and may avoid repeating my error. Purchasing a nut from McMaster Carr might have been a better final product decision, but purchased part QC is not fully reliable either. Our shop purchased a fancy Hyd Mech band saw. The three knobbed wingnut was made out of plastic. It broke within a year and likely had more runout than your demonstration. You repeatedly pointed out that your use doesn't demand a prettier part. Accepting the result in that case and moving on is good practice. If we learn from our experience, craftsmanship improvement might demand more care in a a future experience. I my home shop I routinely discover that I have unexpected limitations mid project. Yesterday I discovered that my workpiece exceeded my lathe chuck holding capacity after roughing out stock with a large hole saw. The hole saw left an unexpected deformation that demanded a work holding challenge to true the intended work holding surface. That project plan mistake forced me to change chuck jaws and that completely altered my intended plans, creating subsequent recovery steps. The other jaws held the work, but interfered with my tooling ater I turned the smaller registering OD. I suffered a whole string of "recovery" steps.

You meant you were showing us how not to use a file on the lathe. 😊 Them Acme threads are something. I just bought a imported tap for 5/8”-5LH and it went right on through.. but the thing doesn’t even thread on a half a turn.. I measured with a thread gauge for acme threads. Then I measured the OD. 16.80 mm ?? Closest I could find was 5/8” so I ASSUMED it was 5/8”. I’m positive it’s not trapezoidal, the pitch gauge fits perfect. But I’m doing something wrong. I noticed how the older machines are made very straightforward and standardized. My Clausing Metosa here is definitely not standardized.. metric with imperial here and there. Such as the acme threads in the tailstock and cross slide. This project has been a challenge to put it mildly. Thanks for sharing ball end nut threading ! 😊

[@mrpete222]

That does cause a big problem when you have machinery or cars that are half and half

[@ellieprice3396]

16mm is .629 so it's not 5/8. Sounds like a metric tap with a different lead than Imperial.

[@jasonhull5712]

@@ellieprice3396 another machinist looked at it and called it out as 17mm trapezoidal. So I ordered two sets of thread pitch gauges and it only matches the “5N” leaf on the Acme thread pitch gauge. This lathe dose has inch/metric dials so it could go either way I guess. But I can tell you I have purchased three different taps and two pitch gauges, two sets of insert type Acme threading lathe tools. And have made numerous test parts. I’m just as lost now as I was when I picked it up to start this project.. 😩

When you are rebuilding a lathe for example and making a new feed nut, you will most likely have to tap. Yep acme taps are huge money I have several in different sizes. I like the tandem taps or two tap sets to relieve the load. However in my experience, they still take some power to get through. Do you have a tandem tap you can show the people Mr Pete? Probably not or you would have I suppose. Cheers.

I do not have a tandem, I’m not even sure where you would buy one. Plus it doubles the cost or maybe I misunderstand you. Sometimes there are two taps. They starting to have a new finishing job, but they may be custom made.

@@mrpete222 They are available at the usual supply houses. McMaster lists the 3/4-6 tandem at $160.00 either LH or RH thread. Not inexpensive by any means. Probably not many folks have them laying around unless they have a need for them. Can't say I blame them. Cheers

​​@@warrenjones744Hate to bring the news to everyone, but that Acme tap IS a tandem tap. Read the information on the shank. All that tandem means is to cut fully deep threads with a single tap.

G'morning Mr. Pete! Perhaps you would consider a video on the making of an expensive tap like that. You have all the equipment. I've searched the world over for information on this and it is scarce. Somewhere between edition 27 and 28, Machinery's Handbook dropped all the data related to taps, and I'm not convinced that editon 26 has a complete reference on the subject. I tried my hand at it, and it's much easier than one would think. Admittedly taps are generally too cheap to make at home because the material cost for the average Joe is more than the tap itself, but for something like a 1/2-12 left hand thread it can make sense to make one at home. Food for thought. I hope this message finds you well!

I took out the spring and put in a different one (longer and lower rate) so it doesn't push so hard, has a more constant pressure and you can nearly push it in all the way to keep from having to keep turning the tails stock wheel.

I think this tap isn't intended for thick materials. This because almost every tip on the tap is cutting all the time. As you can see at 7:00 it needs a lot of torque to proceed. This tap is indeed optimal to start threading and it definitely works best on thinner materials. In this case I don't think it's any better than a "normal" cheaper tap.
