Clearing Up That ACME

- I share my tips on setting up and clearing out an ACME thread. Just about like creating the Acme thread from scratch, I preform all the same motions to set the tooling up and then walk the talk on a project for a friend. ;{)
Keith, I cannot pretend to understand for one minute what you have gone through. You have been as forthcoming as you felt was appropriate, and I hope support has come in a way that was a helpful as your CZcams family can be. There are a lot of us out here praying for you, and for some of us without jobs, that is as much as we can do.
That being said, I know I speak for a LOT of folks when I say “thank you for being back with us and sharing your amazing skills. Your experiences and passion for your work are extremely inspiring, and each video you post teaches us a lesson.
God bless you Keith, and may your shop grow and prosper.
Well said !
Amen! And keep giving the pledge brother. I'm right there with you. I stand at my computer with you while you say it. It actually means something to some of us. We love you brother and we are with you.
God Bless with Fath 👍🔔🔔🔔 .
Justin Rutledge. Thanks for saying in your comment what I also wanted to say but you put it in a much more eloquent way than I could . Yes I am certain that you speak for many of us in Keith's CZcams family .
Very well said. You can be proud of who you are.
Good to have you back sharing your repair knowledge.You're the best, no nonsense, just how to do it.
I can honestly say I saw something new today. I've only ever seen thread worked from the end in - never the middle. Watching you work , mid part, and ease down into it to cut was awe inspiring.
Glad you enjoyed it!
Keith, good to see you back at the "grind". The new shop is going to be awesome!!!!!
Glad to have you back with us!
Man its good seeing you in the shop again sharing videos with us. I guess that means the worlds on the mend :)
Threads are easy if aproached with experience and confidence,
Most people are afraid to do them, the more you do the easier it is. Keith has done these for years. Not a problem for him!! Get out there,cut ACME threads,test yourself,have some fun.

Nice demo of another technique for chasing that thread. Your explanation at the end that the acme tool was narrower than normal made what you were doing picking up the sides make more sense. I may have missed it when you mentioned it at the beginning. Good to see the new shop up and open for business.
Glad it was helpful!
New subscriber here. Very much the pledge as your intro. Kind ago I took an oath to defend the constitution from all enemies and still live by it today. And your machining is amazing.
Glad to see your back to work sir. Been thru family court myself. Life gets better. Plus hard work is good for the soul. Just make sure you don’t kill yourself doing it. Keep powering through.
Thanks for this! It might be common to a lot of your viewers, but my mentor never actually showed me how this was done, only explained, before we parted ways. All of a sudden all his ramblings made sense. Keep up the good work.
I'm happy to see you back making videos. I am in awe over your strength and old fashioned grit to have gone through what you have and still create content for your CZcams family. I might have said to check with it all and given up if I were in you shoes. Bless you.
What a coincidence!!!! I have to turn a 1 1/2”-4 Acme Lefthand thread for a job. Never done it before and this was great timing. Thanks!
Dang Brother, I'm just glad to see you are healthy and back on You Tube.
Always nice to see you upload something new.
It seems we all start off young and dumb, then the more you learn the older you get until you have all the knowledge and then your body starts to become your limiting factor.
I hope you have many more years of good health and keep passing on the knowledge for the next generation.
Lord knows we need more people like you.
Great job Keith as per normal.
Every one else would be turning on the root, and create more problems.
Thanks for sharing and onwards and upwards.
Keith,
That converter noise is a bit loud compared to the old shop, but we'll get used to it in time.
Your new digs look a lot bigger than the old shop...room to breath and to grow.
Glad you're back Professor!
Dan
He didn’t have to use a 3-phase converter in the old shop, but now he does because the local power co is slow in running 3-phase for Keith.
@@joeylawn36111 If one can wait for power till it is convenient for Power Company,like another job in the area it is cheaper hook up. On demand expensive!!
Hi Keith been waiting!!!!!!!!!!!!!!!!!!1
...my favorite subject...repairing threads in the lathe...thanks for posting...
You are a true inspiration in many ways Keith! A true Craftsman.
GOD, I love the sound of that lathe. Everything is all right when I hear that sound.
Hello Keith. That was an interesting set up for working on both flanks of the thread. David Wilks (another machinist on youtube) uses the same method to cut multiple start threads. Instead of indexing the chuck with the leasdscrew disconnected from the spindle (how you're taught in school), he sets the compound to zero (like you did), cuts the first thread and then moves the compound a distance equal to half the pitch of the thread (for a two start thread), and cuts the second thread. I've yet to try it but it sounds easier than indexing the spindle. Ken
I like that Keith where you grind it a bit narrower and come in and take a little off each side. Interesting set up with the compound adjusting it left and right. It’s great to have ya back on CZcams! I like seeing the jobs that come through your shop and how you tackle them. Real life projects and problems to solve in the process. Thanks for sharing your extensive knowledge base. 💥✨👏
Thanks for sharing you work & life with us Keith.
I can feel and see that you have been thru a lot.
Please know that we get great joy in watching you work, and seeing a lifetime of knowledge expressed with each project.
Take your time,... We're here for you.
Peace and Love brother,... That's all we need.
New shop looks great. So happy to see you doing video's again. Stay safe. Thanks
As always, I can't think of anything that would take me away from watching your work. Your sincerity to do good work shows a great machinist.
I thought the way you set up the lathe to match the thread on the acme screw was very interesting to say the least. I can't wait to try it out. Just to see if I can do it. I noticed during the video that the Old Clausing Cross Slide still has a bit of slop in it. I know the slop has been in the cross slide at least since 2015. I'm 75 Keith, will I get to see how you tighten up the cross slide in my lifetime? You have no idea how great it is (for your subscribers, me included) to see you publishing videos again. The new shop looks pretty darn good. Lord willing and the Creek don't rise, I hope to make a trip to The Cape and check out the new shop. Live long and prosper!
Keith, thank You for this information. What I learned here is that the ACME tool does not need to be the final width of the thread groove, it can be less. The method of adjusting the thread groove width with compound is not only a comfortable way to do this but it is also counteracting the chatter as it is cutting one edge at a time.
So, easier to grind the tool, easier to make the thread. Please, accept my easy thank You.
Great tips as always, especially the compound setup for chasing. Thanks Keith 👌
Good to see you are in the new shop.
Wow, three videos in 4 days! Great to see you back and walking the talk Keith. Makes things seem just a little more “Wright” with the world again.
Great seeing you working on your new shop. I really enjoyed your last two videos. I hope your shop will grow along with the community. And in the words of Mr Fenner “Get ER DONE”
Good to see you Keith. I've actually met him at his old shop as nice a guy you could meet. And a master at his craft. We need many more Keith Fenners.
Like I said a couple of vids back, sure is good to see you making videos again, Keith!
Man, I've chased a lot of buggered regular threads, and made my share of Acme rods, but have never had to do a clean-up like this. Even us old dogs can enjoy stuff like this.
Thanks Keith, and we're all pullin' for ya!
Dean
Thanks Keith, great to see you back in action! Dave in RI
Keith,
You made picking up that thread look so easy! Every time I've done it, it's been much more error than trial, LOL! In the future, I'll definitely use what you taught me today!
Thank you for another great video, please keep them coming! It's great to have you back!
All the best,
Jon
Great set up tips, but your hand-eye coordination is something that just cant be taught, every thread chasing job is just 1 mistake away from a trashed part, love watching you work, also adding in a camera is another level of complexity.
10,000 hours.
@@DomManInT1 Young gun then 😉
Many of us can do this, showing how it done, priceless. Bring it all back to me, thanks
So happy to see you, let alone one of your videos! Love having you back
Its good to see you in the new shop!
GREAT to see you back! I feel your pain young man- I just closed on a commercial building, that had been abandoned and vandalized and looted for 8 years!!! Local power company sent an "Engineer" to meet me, and they want me to get blueprints, and drawings and a safety inspection from the county, and this, and that, etc etc costing me THOUSANDS just to get my power on in this new building, not to mention all the huge wire that was cut (while it was live) outside between the meter can and the transformer, by looters & crack heads has to be replaced underground!
I'm getting there slowly, but have been working on cleaning the place up with a single phase 220v gas generator for fans and power tools!!!
Once I get it all restored I'll have a 400A three phase service, with 277/480 and a separate panel for 208/220/110 - but it's gunna take time and weeks (many)
Stories like this made me crazy about such stupid people who in my opinion never build something and they cant apreciate effort of somebody else made to build up something valuable from scratch. Vrrrrrr... Hope you will do better and better. Greetings from Europe.
30 years ago when I got a new shop the power company wanted $8K to set a 3 phase transformer. After I found the right person to talk to, deep inside the power co. and he told me how to go about making my application more suited to the higher ups, they then set it for free. Started with 400A 208V. That may have been a mistake because as I added tools I needed 400 & 480V. Ended up with a lot of transformers. It is a lot cheaper to wire for 480V. Also had to have another service brought in to get to 800A. City originally required an industrial panel with each breaker costing $350 back then. I now have 7 sub panels. Plan a head.
Good to have you back Keith
I really missed these machining videos. Welcome back, Keith! 🔧😊👍
Welcome back Keith hope every thing is going well
It's great to see you back Keith. Your first 2 videos 'pineapple ones' were fantastic. I wish you all the success in the world in your new shop and hope you keep the videos coming, it's vital that us 'learners' learn from the best.
Keith, great video. I'm a new subscriber so I have a lot to catch up on. I've been around enough to know that you are highly skilled and a true craftsmen. This ACME thread video and tips certainly encouraged me to try and clean up the ACME threads on my South Bend 13" compound feed. I tried a file from a small set but it took hours to find the low and high spots to work on. Thank you so much
I’ve never thought to do acme threads that way. I like the idea! Thank you!
Good tip on rotating the compound to be able to work and cleanup both sides of the thread. Good one....! Thanks for sharing that one....!
G'Day Keith,,Mate had me back into 1976 where i had lathe training as part of the trade,(Fitter and Machinist,),yep right hand and left hand internal and external fitted to-gether on a test piece,,Knurl the outer nut and then relieve each one ,,yes had to be marked,pass mark 80%
mind when i went to tech,,Hmm Trade school,,had every thing i needed to ace the class,
the old BHP training was the best ever,,,if you ever get a bloke done training at BHP,( yes even a dud,),there will be not much you could teach him,,
But enjoyed remembering,the experience of doing it,,
this was all after learning boring to a plug gauge,,,The tolerances were so close,a couple of degrees in temp,,had a lot of plug gauges stuck in bore hole,,
mind nothing a quick hit with the oxy couldn't fix,,
Good tips on lining up the thread engagement. Thanks for sharing.
Great video, chasing threads is something I have been working on, the fact they are ACME is a bonus!!! Thanks Keith!!!!
That was a simple job for you Keith , that was simply amazing to me !
GREAT TO HAVE YOU BACK, KEITH...
hi new shop is looking very good love it.best of luck
Thanks for the video. I always enjoy them.
Good to have it back! I hope it feels good to be back too.
Great video Keith. Stinks about the way the power company is acting.
We've determined this is a #4 ACME thread. Pulls out a steel jaw rabbit trap hes had for a long time to show us how ❤
Good to see you again. Great video
I like the way you did that, will grind my acme threading tool a little small next time I use one. Thanks for sharing
God bless
Stay safe
Great to see you back Keith.
I was literally wondering about how one would chase/clean up pre-existing threads on a lathe the other day. Now I know!
One thing he did not explain or demonstrate is that you can start the spindle and engage the half nut and then stop the spindle leaving the half nut engaged and use the compound and cross slide to align the tool with the thread. It does not have to be done with the spindle running. Much easier for someone less experienced.
@@DomManInT1 ,Correct . been doing it that way for donkeys years but it still needs fine adjustments just the same as Keith used with compound slide.
@@karlhrdylicka Yeah. For years. That top slide has been called a compound.
@@DomManInT1 Excellent advise, All new learing threaders should learn this technique first. Always leaves one less chance to bug the thread.
@@DomManInT1 Yes,Senior moment . you''ll get them when your as old as me .Guessing your not English as the description top slide was also used before CNC made it obsolete. I will add an edit . The Colchester lathe Keith is using is the same as the one I have , mine is shorter bed . had it since 1971. and still use it . You can think what you like I don't have to prove anything to anyone .
far out you cant have anyone looking over your shoulder asking questions when you are working free hand like that ,,,man thats some skill !
Good to see you back Keith!
Very interesting. Thanks for the tips and tricks.
Just that tip to tell if your tool is too low or too high was worth watching the video. Thank you!
Great video Keith, thanks for sharing
Have not seen you on u tube for quite a wile glad to see you back.
One nation under God, thanks Keith
Excellent start Keith
Good to see You back Keith ,especially on that lathe with the carriage handle on the "right side"(Colchester)
Glad to have you back. Ditto what Justin said man.
Great video, Keith. Looking forward to many more, as your time permits. Thank you for sharing your time and talents with us. Charlie
His pull-out game is on point!! Ha. Ha
Good video Kieth great to see you back . All th e best for the future !
Great info Keith, thanks for sharing.
Great video. Great explanation of work. Thank you for sharing.
haha... your electrical panel looks just like mine at the moment! Now to watch the rest of the video!
Sir! You could put up a video of almost anything. It would be a good one just to see you working and putting them out, is a well waited for event. Thank you!
Another slick trick from the old machine Master... Thanks, See Ya I rang the bell..
Awesome video, glad your back at it .
Again a great video! Glad you're back!
Always nice to have a quick simple job. You knocked it out well! :-)
Thank you so much for your opening "PLEDGE" and of course for your wonderfull videos.
You are so welcome!
My favorite machinist is back making chips and video
Welcome back
So good to see you back and "Gettin er done"
Thanks for the shared knowledge!
Welcome back, nice to see you again.
When i used to cut Acme threads i used to drink Acme BEER to help things along the way they don't Brew Acme Beer anymore so I'm screwed . 🐤😁😁
👍👍👍👍 for what its worth, I tied a 20$ wireless remote switch I got off of Amazon into the control circuit of my rotophase. Sure makes it nice. Surprisingly I can turn it on and off from the house 300' away.
Yay! Keith is back.
Wow! Great tips, all around. Where most have iron in the blood, you have high speed steel. Get-er-done!
Hi Keith, As apprenticeships dwindle even further it would be great to hear about your apprenticeship experience and about your mentors.
You almost make it look like I could do it. And I haven't touched a horizontal spinny thing since ruining some knurls for class in 1985.
Like always I appreciate and learned thanks Keith 📐⚙️🔩
I wish I could have apprenticed under you Keith!
Looking good Keith ! Good to see that you are back, have fun, be safe, stay healthy, all that ! Best of luck :)
Have been away from metalworking machinery myself for the last year and the forseeable future because the guy owning the shop lost it (litterally, not just some personal disagreement...). Id love to build my own shop, just as a hobby, was never my main job anyways, but realistically i have to wait till my current job is over because it pays well but will only be a couple years and i don't know where i will live from then on.... man...i sure miss a good lathe :/
Threads are always one Turn away from being Wright. (orbit gum tooth ding sound) Good to see you here.
Great video! Thank you. 👍👍👍
Hast du wie immer super gemacht!! sehr schön mach weiter so!!👍👍👍
It is a neat lesson. Thanks.
