Making A New Cross Feed Screw | Lion Lathe Restoration

“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.

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.

Ive never cut an acme thread, really enjoyed watching that

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

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

Hi Kyle, Thanks for sharing yet another great video. Always nice to follow you and your work on YouTube. 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.

Nice job. Follow rest was awesome!

This was great to watch. Nice work!

Great video, enjoyed watching the process. Cheers

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.

Beautiful work 👍🏻👍🏻👍🏻🇬🇧

wonderful work, thank you for sharing, Paul in Florida

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

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!!!

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