I’ve watched your channel for years now. I bought my first lathe because of the potential I could see to save money on the farm. You’ve saved me tens of thousands through this channel by simply being able to do the minor odd machining jobs that help keep tractors and 100+ year old hay equipment running!
Wow, that’s fantastic! I doubt I’ll ever have a lathe but I tell you what, if ever I’m in a situation where there’s a lathe and no one else knows how to run it, well, I know what I know from Adam Booth!
Can we just appreciate Adam turning a 32TPI thread and stopping the tool almost exactly 1/32" before the end each time without a runout area. Any time I try stuff like that I drive the tool right into uncut material usually ending in a disaster. A true craftsman!
As an old lady It amazes me how interesting and fascinating this is. I wish I could have done this work as a career, but the world was not like that in those days. Ladies didn’t do this work. I am starting it as a hobby now. Thank you for teaching me what you know.
Well back in the Second World War there were probably more female machinists on both sides than the men, many of them being conscripted to serve in the forces. Certainly here in England many many women were working lathes in munition, aircraft and probably shipyards throughout the war. They only went back to being wives mothers or sweethearts when the men came home and wanted their old jobs though not necessarily old employers back.
Next to Mr. Pete you are the most enjoyable machinist on RUclips to watch, I like your honesty when something goes wrong, no excuses just plain old honesty, Thank you so much for your wonderful videos.
I am a Chinese。when I was eighteen age ，I worked at a state company， that manufactured heavy lathe in Shanghai . My master teaches me how to make the Acme lead screw. This video brought my memories back in 2000.
I am a Machinist for 35 years or a bit more ,,, your ability to SPEED thread , hand / eye manual threading at HIGH RPM is second to none IMO. .. Great Job ,, Best regards John
Thank you! I am utilizing your channel to support one of my recent school graduate/former students who is heading to Mechanical Engineering school in Georgia. I have an old small lathe that I had him turn last week, but your channel is his homework. He’s great in the book, but his hands are smoother than a baby’s bottom! Hopefully we can give this young man a leg up at G tech by familiarizing him with practical knowledge! Thank you as always, -CY Castor
Frankly I don't think new machines are built to the same standard as th he new ones. Although a few years before I retired we got a new Harrison around 12 or 14 inch swing with about 60 inches between centers. Built in Poland. Nice lathe. Firm yet smooth controls with variable speed in three ranges. Inch and metric gear box.
I live in Germany and was at the university in Giessen for over 40 years. Giessen was the home of Heyligenstaedt, one of the great names in German machines. I'm spoiled.
The First real job for the Precision Mathews Lathe. How very nice to seeing this lathe making it's first part. Being a new machine this will take some getting use to operating. What a better way to start.
Nice. After watching these last few years, I could actually enjoy seeing the threads bearing cut by the left hand side of the tool. I could even see the mark on the left side where the chip fed over the tool. Several years ago I would not have had any idea what was going on there. You are a good teacher.
just saw this pop up on my feed….I haven’t even watched it yet and I felt the need to comment…. I HAVE BEEN SOOOOOOOOOO LOOKING FORWARD TO THIS VIDEO!!!
A couple more things. I use an old Summit 19x80 that was given to me when I retired. I bought a couple of newer used Bridgeports with a lot of wear. I found that I could remove .015-.020" from the sides of the ACME screw and use the double brass nuts to take the slack out. Saved about $400.00 for a new lead screw.
The technique as I commented in the video where the threading failed, although the insert manufacturer says that it is not necessary to lubricate, the behavior of the material makes lubrication necessary. It can be seen in the finish, and that at no time does it use sandpaper or file since they are not necessary. Congratulations on the ADAM demonstration La técnica como lo comente en el video donde fallo el roscado, aunque el fabricante del inserto dice que no es necesario lubricar, el comportamiento del material hace que sea necesaria la lubricación. Se puede apreciar en el acabado, y que en ningún momento emplea ni lija ni lima ya que no son necesarios. Felicitaciones por la demostración ADAM
I said to myself today that I as wondering when we get to see the lead screw video and here it is. Great job. Must be really nice to work with new and accurate equipment.
I love seeing the mistakes and failures. It’s just as useful as seeing it done right cause it helps you troubleshoot if you ever run into something similar. Imo showing your failures makes you appear to be a better machinist. Nothing in life ever works out perfect every time. It’s how you overcome the problems that matters.
I work with a similar Cyclematic lathe also made in Taiwan with flood coolant with an electronic gearbox and I gotta say they aren't bad at all. I only wish that they had a bit more cast iron for more rigidity like old school lathes but for jobs like this they're perfect. If you end up with a few snug spots when testing out your nut, sometimes taking 1-2 spring passes at your final thread depth helps smoothen things out without adding extra backlash.
Love the lathe and making your own parts to fix your own machine is prime. Most people don't know the feeling of being able to do that. I enjoyed watching you work. Keep em coming.
You've been doing this long enough that I'm sure it's hard to find creative ways to keep the content exciting. I just wanted to say that the top down view while you were cutting those threads was really fun. You've probably done it before, but it stood out this time (probably due to the interesting thread geometry). Nice work- great video!
Well that solves that. When nothing makes sense - buy a new lathe! Mr Abom, you totally deserve this new one and may it work great for you till the day your done turning metal.
I like your methods. One thing I do when getting close to the final nut (or thread guage) fit, I will lightly file the thread to remove any tiny burrs that may be present, and for large threads, I will use a triangle file. I then rub a Cratex Rubberized Abrasive Block to smooth out any roughness present on the thread. I do the filing and the cratex'ing with the machine running. I do this before deciding to take another deeper cut. Once you cut, you can't put it back on. Keep up the great videos.
I started learning how to use machine tools in my early teens and used them for 48 years and I'm still fascinated that metal can be cut away like this!
Even more satisfying doing it yourself especially for a hobbyist. Find yourself even a little small lathe and How To Run A Lathe book and have a blast learning.
Hi Abom. I have watched your work for a while. I am no expert. I used a follower rest to "clean up" the threads on a 48" Bridgeport X-Axis lead screw. I think you can use either angle on the 14 1/2 degree. It just takes metal off the opposite side of the thread. I also use tap magic (I buy 5 gallons at a time) and use an old squirt bottle to add it as needed (409 spray or shout laundry aid or any other type) I also run slower. The other thing i do is make my own ACME thread tool. I use old 1/4" carbide end mills cut off. I sharpen them with a fixture I made on the bridgeport in a vice using a diamond cup wheel. (I cut the flutes off). I bored & reamed a piece of 3/4" case-hardened ground rod (thompson). Added set screw to hold carbide hand made bit. That way, I can rotate the acme slightly to adjust for left or right hand thread. Good Luck.
Very very nice job that turned out very nice keep the videos coming I really enjoy them. Before I became too lazy to work and decided to fly airplanes for a living. I used to do machine work in the younger years. Bring back the old times a little bit really enjoyed watching your videos thank you very much.
You can check thread pitch with the DRO. Turn the chuck to take up backlash, zero the DRO and turn the chuck one turn. It should move one pitch. You don't have to scratch your work piece.
In all the years I did machine work I never got to run a new machine but a couple of times. Usually last one hired got the oldest most abused machine in the shop. When I worked for Boeing you had to "earn" your way up to a new machine or have the most seniority. It is so nice to not have to fight the machine and compensate for stuff due to misuse or just common wear and tear...
Actually, when I was in my early Mechanical Engineering school Machine Shop (ASMET then BSMET) I deliberately went to the oldest LeBlond lathe at the end of the row. The other guys tried to get on the newer machines. Their problem was that they didn't get the same machine twice. One day the old, retired Navy veteran machinist instructor came down and asked me why I picked that machine. I said: "Because nobody else touches her and the old girl is still in good shape. Next time I come in she's just like I left her. Plus, the scrap barrel is ten feet away, and the toolroom is twenty, and those guys are back and forth from the other end of the shop." After the class was done and I got my "A"s on everything I told him my Granddad had been a Bell Aircraft/Lockheed machinist building instrument panels for B-29s. He said: "Runs in the family don't it"? :)
My father used to say ... "If at first you don't succeed, try try try again! I've modernized the saying to ... "If at first you don't succeed, ya damn well better get it right the second try"! Well done, that lathe is SWEET!
Sometimes it takes more than a second try to get it right. You damn well better learn from failure #1 for sure though, and try your best to succeed on attempt #2. But even if it takes attempts 3, 4, and 5, you should still keep trying until you get it right. 💪😎 Some people "3 strikes, I'm out. I'm giving up because I'm obviously not cut out for it." That's a shame, because you should strike out until you hit a home run which very well may be swing #4. 🤷🏻♂️
dude is a beast with manual machines, he has a CNC lathe right next to him !!!, My Monarch 20c 23x72 just went to a new home, the Cincinnati CNC took her place, I was having similar issues with threading and it was a issue of saddle height
Just got my first lathe after watching you for years. I really liked the camera angle that shows how you are using the lathe and the tips about threading. 16:28
One thing that I noticed, that I really liked. When you finish a pass, you back off the cross slide ONLY., then go back to start another pass. Then, you repositon the cross slide back on zero, and move in the compound another 5 thou. I will try this. I usually never touch the cross slide and back out the compound only for the entire job, but I have to quickly remember to go 5 thou past where it was for each pass.
Second times the charm adam , looking forward to more projects in the new workshop keep up the great work , thanks for your time and efforts towards sharing quality machining content & knowledge! A keen follower from across the water.
I really like turning 1144. I started off using 12L14 and 1018 on my 6" lathe but found it handle 1144 great. I up sized to an 11" lathe and still rarely use 12L14 or 1018. 1144 is just a bit more in price than 12L14 and 1018 but close enough in price and leaves a MUCH better finish than 1018.
Both the nuts used as gauges will have radii in their roots. It is prudent to file the sharp crests of the threads before taking finish cuts so the thread is not riding on the sharp peaks engaged in the root radii of the nut. If you keep cutting until the nut fits over the sharp peaks then the thread will be slack when the crests are deburred. If the crests are left sharp, galling can easily occur in use when the sharp points wear into the thread groove.
Quite amazing on many counts. Amazing that he does not know this crucial part of screwcutting. Amazing that no other comments highlight this. Amazing that with new machines he is not using full profile inserts. Amazing that these threads pass inspection with sharp points and burrs. Amazing if this comment remains.
@@ellieprice3396 Hopefully we all were. In almost 50 years I have never seen anyone who did not deburr the crests before checking with a gauge. In the last 20 odd years I haven't seen anyone using inserts without a crest radius. This is a consequence of processes uploaded by folk who never bothered to endure the sacrifices of a formal apprenticeship.
GHT wrote a piece of cutting left hand acme threads, perhaps not an issue with a new, large lathe without backlash on the leadscrew but the problem he had was when the tool pops out of the thread near the tailstock it looses "support" on the right hand size and the last bit of the thread will then lack consistency so when you get the nut to engage on the end it will then be loose on the rest of the thread. Remedy was it seems to cut the thread from right to left in reverse with the tool upside down.
the machinery's hand book author myst been one hell of a master to come up with tolerances and the whole shebang its amazing when stop think about it going from black smithing to the first lathe up through it is absolutely amazing!!
Greetings from Yorkshire dude. It's a total joy to see how happy you are doing what you do, and clearly doing it so well. Here's to you and yours mate.
Congratulations Adam. I’m always glad to see small business owners expand and grow their business. The joy and pride you have in your, new from the manufacturer, equipment is pretty obvious. Wishing you continued success. 👍🏻
It’s good to see that everyone fails or that the machines don’t work perfectly now and then. I know that from time to time, things don’t work out. There are times that it’s my fault and times it’s not and it just doesn’t work out, for reasons that make no sense Yup... it’s not a great feeling either way. It happens to the best and in every industry. It’s just part of “ Doing “
Great to see the new lathe working so good Adam. That new lathe looks nice and tight so I hope you have lots of hours of video to show on the new machines
There was something I didn't notice till you mentioned it in the closing comments. That machine is super-quiiiiet! Here's a vid idea, 'machine trivia -- noise levels'. For your phone get an audio level meter. For different machines, stand at the usual operator position and hold the meter in front of you and see what they say. With charts 'n graphs 'n a paragraph on the back of each one to describe the data.
Re; 29:36....Lock your doors and get a door bell and door camera Adam. Also can put big screen monitors on a few walls to observe doorways & surroundings. Not funny to not hear "guests" coming into the shop.
I had much the same problem with my follow rest. My solution was to make a complete new follow rest out of 1" plate that ties down to my cross slide. By tying it to the cross slide I could line it up exactly with my tool so the forces of up and back were totally under control without any torsional deflection of any kind.
I was surprised you went for a new Precision Matthews lathe for your like of older machinery. Plus, I didn't realize they made such nice equipment as I always thought they made high end hobby equipment. Boy, was I wrong. Congrats on the new shop.

Remedy was it seems to cut the thread from right to left in reverse with the tool upside down.
Or even easier, just cut a taper at the far end so the tool unloads slowly (in a controlled manner) rather than just ending up in "free air".
the machinery's hand book author myst been one hell of a master to come up with tolerances and the whole shebang its amazing when stop think about it going from black smithing to the first lathe up through it is absolutely amazing!!
More than likely, the book is a compilation of information gathered from 100's of sources, and is added to every few years.
Greetings from Yorkshire dude. It's a total joy to see how happy you are doing what you do, and clearly doing it so well. Here's to you and yours mate.
First Chips on an actual Part
YEAH!!!!
First job on a new lathe. Make a cross feed screw for lathe+ compound slide screw. Always had big backlash with shop lathes. Nice thread.
No frustration, like the last lead screw..part looks beautiful 👏
It's nice to be happy with what you have achieved.
Congratulations Adam. I’m always glad to see small business owners expand and grow their business. The joy and pride you have in your, new from the manufacturer, equipment is pretty obvious. Wishing you continued success. 👍🏻
These tools will be awesome to pass down to your children and the knowledge passed down as your grand dad and dad did for you.
It’s good to see that everyone fails or that the machines don’t work perfectly now and then. I know that from time to time, things don’t work out.
There are times that it’s my fault and times it’s not and it just doesn’t work out,
for reasons that make no sense
Yup... it’s not a great feeling either way.
It happens to the best and in every industry. It’s just part of “ Doing “
your ear-to-ear smiles tell the whole story!
The new machine seems real smooth.
I like the work lamp as it does a real nice job of illuminating the work piece
We used to do a special "acme thread" lead screws 50-60 mm in dia and 4-5 meters long
Great to see the new lathe working so good Adam.
That new lathe looks nice and tight so I hope you have lots of hours of video to show on the new machines
Last time I was glad Abby was there when you tried that! Because if she wasn’t I know something was going to get thrown across the room! Lol
Very impressed with the precision Mathew’s and Adams talent
Great video again Adam. I am so glad it has all working out for you by getting the part made and throwing a few chips on the new lathe.
There was something I didn't notice till you mentioned it in the closing comments. That machine is super-quiiiiet! Here's a vid idea, 'machine trivia -- noise levels'. For your phone get an audio level meter. For different machines, stand at the usual operator position and hold the meter in front of you and see what they say. With charts 'n graphs 'n a paragraph on the back of each one to describe the data.
Audio level while making 1/2inch chips.
There’s something satisfying with these large thread cutting ops. Kinda like watching the shaper. Oddly satisfying.
Nice work Abom in both your machining and production. Thanks very much!
I can see the excitement in your eyes to use a use a new machine
Adam, so awesome to see work coming out of the new machinery. Good on you!
Nice job. That's a sweet lathe. Always wondered what a brand new machine feels like.
Re; 29:36....Lock your doors and get a door bell and door camera Adam. Also can put big screen monitors on a few walls to observe doorways & surroundings. Not funny to not hear "guests" coming into the shop.
This is the one I’ve been waiting for.
Maybe you can build a follower rest using the slots in the machine opposite of the tool. Seems like a project that with your skillset should be easy.
Makes me want to redo my compound and crosslide after seeing how much better new machine cuts zero backlash makes a mister difference it appears
Coors light, Saturday night, a video from Adam…. Life is good 😊
I had much the same problem with my follow rest. My solution was to make a complete new follow rest out of 1" plate that ties down to my cross slide. By tying it to the cross slide I could line it up exactly with my tool so the forces of up and back were totally under control without any torsional deflection of any kind.
On thread cutting I am very concentrated like You. But watching someone other on thread cutting is very relaxing for me!
It's always a pleasure to look at great work like that !
An amazing technician with new technology Enjoy every show. May the Lord richly bless you.
great that it was a success with the new lathe
Thank u Jesus !
The 1st time I've been nervous watching one of Abom's videos,, lol...
I'm 11 minutes in can't wait to see how it comes out...
Those old machines are really cool but a really good new machine is really nice to have!
Hi mate I like the way that you didn’t give Up and I was looking forward to seeing the results
I was surprised you went for a new Precision Matthews lathe for your like of older machinery. Plus, I didn't realize they made such nice equipment as I always thought they made high end hobby equipment. Boy, was I wrong. Congrats on the new shop.
Sometime it is worth firin' up the ol' laptop and looking at those new fangled 'web sites'!! A lot of useful info to be found there!
Haven't even watched the vid yet but just love the title. Round 2 indeed!
Nice piece of work.
Fantastic job Adam!
