Techograhy! Many are accomplished machinists. Conveying those skills to the viewer requires another level of skill . You are something special because the Videograpy in this video is exceptional! Wakodahatchee Chris

“Overkill” should be your middle name! Nicely done, and I really enjoyed watching you work. Thank you!

When making undercuts for threading, the shaft will be stronger if you leave a radius in the corners by using a round-nose grooving tool instead of a cut-off tool.

You do a fantastic job with these long form project videos. They are great, thanks for taking the time to make them for everyone!

Well done, end result looks good. Rolled lead screws are generally stronger due to strength hardening but in general are less accurate depending on the manufacturer tolerances. Edit: and forgot to mention, you should be using flood coolant or more thread cutting oil.

Ive never cut an acme thread, really enjoyed watching that

I really enjoyed this video with you challenging yourself to see how accurate you could be. It's rare that we don't make a flaw while making a complicated part. It speaks to your confidence that you pointed it out for all to see. Nice job making that part and documenting it.

Hi Kyle, Thanks for sharing yet another great video. Always nice to follow you and your work on KZfaq. If I may, I suggest you use lathe files to do your edge deburring and chamfering. Also when cutting your threads, if there is the slightest amount of burr, it will score badly and immediately your brass points on the steady rest. This job you did is quite challenging and I hope that once you get the nut done, it will be perfect the hole way on the screw. As for the key way, I would probably used the climbing method as it would put the cutting force on the jack, witch is the reason for using one. Otherwise you get a lifting force and increase tool and part vibration/deviation. You did well to reduce the RPM on the acme thread cutting. Make sure you lubricate intensively as you cut such thread. Tool pressure is immense, as well as contact area. I endorse cutting oil!! God Bless.

I think you should do as I did and add a drip oiler to your rest. It's one less thing to worry about, and it's simple in construction.

Love the follow rest, that’s a great set up. I learn something new every video you make.

I think everyone has said it for me! Thanks

Great video. I enjoyed watching the thread cutting process. I’ve only done a few threads and fought with each of them. However, there is hope as they seem to be getting better. Thanks for all the good effort and camera work.

This was great to watch. Nice work!

Nice job. Follow rest was awesome!

you should get a mist lubricator lot easier than a can of oil. Kool Mist 60M12 PORTaMIST Unit, Magnetic Nozzle Positioner, 12" Flexline. topper machine uses it a lot in his videos

Great video, enjoyed watching the process. Cheers

You are brilliant and proud of your work. All of the Best for your future projects. Cheers.

Beautiful work 👍🏻👍🏻👍🏻🇬🇧

wonderful work, thank you for sharing, Paul in Florida

Nice work as ever and logical, always funny to see folks still working to banana dims .your fixture table ranks alongside Stonehenge for the “durable” status.love it

Just recently turned a new x axis leadscrew for my knee mill. My lathe is almost 100 years old, it came with the frames for the follow and steady rests but no fingers. I used soft window weight gray cast iron for the fingers in the follow rest and it seems to do well in the wear department at least enough to get me through most of the process without having to adjust to account for wear. I ended up using 1045 tg&p for my screw, i wanted to used a piece of 1144 tg&p but i ordered a 1.250" round bar hoping to not have to do a bunch of turning but the bar was bent:( The 1045 yielded a less than desirable finish but it works. Nice job on your screw, looks good!!!

You do nice work

love your narration .......

Your processing skills are truly amazing.🎉🎉🎉🎉🎉😊😊😊😊😊

It is for you so only underkill applies, Nice work you had more guts than me during chatter segments. Ray Stormont

Well done. 👍

Great explanation and detail. Subbed here.

Good stuff

Turned out great. I think your cross slide screw is as long as the bed on my South Bend. LOL!

Metric is a standard thread pitch worldwide, just not in Murica.

A follow rest? Is that how its referred to in the US? In the UK we call it a travelling steady.Great videos by the way.🤙

Does that Pacemaker have thread reversing on the Apron? Most of the ones that I operated in the Navy Yards did. That's a handy feature to have if you do a lot of threading. No need for using the thread chasing dial, just engage and reverse. The lathes that had it also had stops.

Great video, enjoyed watching your process and attention to detail along with your narrative. Your follow rest worked great. Q. You probably mentioned or it maybe an optical illusion but the shafts side by side appeared to show the new on much shorter than the original, please explain. Thanks for sharing.

As you tighten the follow rest between passes, how do you know (or verify) that you are not forcing the shaft out of alignment?

Listen A new cross feed screw

el polvo de esmeril malogra, la bancada del torno, esta debe de protegerse bastante

Why not use some ball bearings on the follow rest instead of the rubbing brass ? Is that done ? Pros/cons ?

"Honey!!! It's happening!!!"

How come it is shorter?

Is it shorter? or just looks shorter?

Why is it shorter than the original?

What material did you make that screw out of?

nice work but 1144 will not last but may be better than what was in there.

Congratulation you building your own flow rest, NOTE with tree point tach the material. Do you have a good Lathe the casting bed has two prismatic guide . Most CHINESSE follow rest became ,with only two points MADE CHEAP $$$, WILL no good for do this type of work, only the Machinist decide the tools ,not the plant Manager. .Bay the way very good are you threading the proper way, no to many Lathe operator no this old school ,MAKE AMERICA GREAT AGAIN . Bay from ARGENTINA - CANADA.

you should learn a bit about feed and speed, it disappeared as much from the saw blade as the shaft .. by the way, the vibrations came from too little chip depth, the shaft is meant to be pressed up against the support otherwise it will vibrate + you can drive 5 times faster in revolutions

By no means am I a machinist but could you not put a pair of shoes on the follower rest for better support on the threads

1144 steel

1 minute in: we have standard, and we have metric, so we make a standard thread.... METRIC IS THE STANDARD!

around the minute 21 what was that "chatter" ?? why only in that part? is this some material composition thing? please don't do anything off camera 😢 that sucks haha good job man! r

Convert metric to standard - only Americans can relate 😅

This is how I did for similar project: kzfaq.info/get/bejne/a7aRgbeDms6XZ4k.html

i´ll hope you dont make the screw in the same machine that you gonna use it on.🙂

You lost me when you said you need a straight bit of material to use a travelling steady, you don't, all you do is have the steady following the cut, not leading it......
