Keith you are not alone when you say every time you start a job you have to work on something to fix it. It seems like the older I get the more i run into this. I really enjoy watching your videos. I spent almost 30 years managing a tool and die shop so most of this is right up my alley. Again I really like watching your videos and also David Richards Old Steam Powered Machine shop. Thanks for taking the time to make these videos.
Just think of it as your absence just makes us enjoy your videos that much more! Looking forward to meeting you at the Bash, I always like to say thanks in person. You are a good teacher!
Nice to see a full blown Project in your new workshop. I look forward to every episode. I am retired but find I am busy doing all the things I could not do when I was working full time so when it's K Rucker video time. I watch and unwind. Take all the time you need. Thank's for all the great video's.
Thanks Keith. I must say that with everything else in your life, it's amazing that you are able to keep up the great content. And remember, even the back steps are an education for us.
I know that feeling, Keith, where you really get into a project and then you realize you can't finish it because another element that needs to be finished first, I'm finding myself in this situation way more than I like. But you’ll getter done. Thanks for another wonderful viewing experience. Have fun with the guys in California.
Good Lord ... Stop apologising for being busy. Holding down a full time job, supporting a family, volunteering at a museum, holding training classes, going to swap meets AND making quality TH-cam videos ... Take all the time you need ... we'll wait.
Yeah, don't worry about the apologies. You owe us nothing. Besides we all work on projects that spawn additional sub-projects. Especially when you are just getting things set up in that space. It's like when you hire a new person to increase productivity. No matter how good the person is productivity takes an initial hit. Well you have a couple new guys on the payroll. The shop and the lathe. We have time to wait sir. Thank you for everything.
iamthetarget52 But his courtesy is one of the things that makes him such a joy to follow. And, I believe, an important part of his being. But I do forgive him. Absolutely forgive him.
Don't worry about the thread dial just leave the half nuts engaged and run the carriage back and forth. It will take a little longer but not nearly as long as reconditioning the tread dial. Nice video!
Just an FYI, SoCal is under heat watch. Expect temps in excess of 100 degrees F at the Bash. I actually live in the Desert on the opposite side of the Mountains behind Rancho and we are expecting 110+. Wish I could see you at the Bash, unfortunately we will be leaving the state on that Saturday. Love what you are doing and I've learned so much.
I am actually flying home from the Bash as I am replying to this comment. Temps were hot, but we got a "cool spell" just in time for the bash. I think it was only 91 degrees F on Friday and 96 on Saturday. Hot but not as bad as a few years ago when it was something like 107 degrees F!
Very nice to see that pristinely restored LeBlond in action. To fit the pristine picture the collet chuck could use a little shining up. But I guess there are many other things higher on your priority list. B.t.w you don't need the thread dial. You could leave the half nuts engaged and turn the lathe backwards to back up (actually forwards for LH thread). But I am sure you know that very well.
I know what you mean about having to stop and work on things. We purchased a well used mortar mixer many years ago and was given an electric motor that would drive it just fine. The problem was that the old set up was for a low RPM motor and that newer motor was 3600 RPM. So, we had to put a jack shaft in to reduce the speed to an acceptable rate. Easy fix except there was a clearance problem. After a lot of rearranging we got her going; worth the wait as we used it several years till I had to retire due to disability. Get r done, oops I did it again Keith, Greg.
Great work Keith. I use dies to thread on my lathe quite often, my lathe is very fiddly to set up for threading since it has no quick change gear box so it's much faster for me to use a die than to calculate and change gears out all the time.
Hi Keith, Try running a form tool upside down and the spindle in reverse. You get the equivilent goeometry to a spring tool-holder and reduce or eliminate chatter.
Thanks for sharing. The story of my life; I've got too many "yaks to shave" every time I want to do something :) Looking forward to watching the follow-up.
Keith, use coolant on 4140, it tends to harden quite quickly in a cut. That's been my experience at least. Notice how the color of chips changed a few seconds before 25:15, to me that looks like a hard chip. I had this problem one day. I got around it that night with a paint sprayer to get the job done, now I use a mister all the time.
Another fun and interesting video. You can take your time posting videos if you get busy at home, work. TH-cam is not as important as other parts of life. Yes, I look forward to your videos and if it takes you more time, it's OK.
Seems that every project I have going on is linked to another in some way, one can't be finished until another one is. For lack of one specific tool, usually. If you have money, you don't have time, and vise/versa. The vicious cycle that sometimes seems like you will never get free of it. There is a story I was told about earlier days of railroading in Arkansas. There was a rule concerning trains that met at interlocking tracks at the same time. The rule was "neither shall go until the other has passed." With these projects, you have to wonder if what you are feeling about them is how those conductors felt in those situations.
The problems you were having with depth of cut seem like they're more from tool geometry, rather than machine rigidity. I've taken off 200 thousandths in 4140 on a Hardinge HLV, it seems like that 12" Leblond should be able to do a hell of a lot more than 60
Keith can you get somebody to look at your mic lead? I believe it has had a good tug and is now beginning the slow decline. As always, the installment is very illuminating
Would it not be possible to cut the thread without the thread dial by not disengaging the threading screw at the end and run the cutter back by reversing the lathe spindle?
I noticed that you don't back off the cutter when returning to the beginning to make the next cut,stating the finish wasn't smooth enough. I have seen Adam Booth back out just a bit when returning to the next cut, from start to final finish cut. I am not a machinist, might this procedure of backing out have some relevance as to the roughness versus the desire for a smoother finish?
I have a old cluising lathe and i am now on ssi and want to learn how to use it since i have time to do that now but it does need alot of work to it to make it all work right i wanted to know if you can make a cross feed screw and nut for it if so how much would it cost me and i can send you my old parts to referance off of but they are badly worn
We use Kurt vises at our shop every day and I noticed that the soft jaw on your vise was on backwards. The set screw faces the rear (user) rather than then fixed jaw. Maybe Kurt made some the other way but, I think that yours has been removed and replaced sdrawkcab (backwards). TW
I was hoping you'd show off some skills and thread without the dial. If your leadscrew is 4 or 8 tpi you wouldn't need it anyway for the 8 tpi threading job. And leaving the half nut engaged the whole time is pretty much mandatory if you want to do metric threads, so its a good technique to learn. But sometimes its nice to have an excuse so you can go relax, in which case I don't blame you for being unable to finish without the thread dial!
I recall from Adam Booth's discussion of thread cutting that there are certain combinations of thread pitch and lead screw pitch that don't require use of the threading dial -- anywhere you engage the half-nut will be correct. I wonder if you're lucky enough to be at one of those "magic' combinations in this situation.
I think we're both saying the same thing. As I understand it, the half-nuts won't engage between divisions, so "any division" equals "anywhere". Would be nice to have an expert to confirm.
If you do that, you might have runout and not get the hole in the center. Better to do it chucked up close to the headstock and then move it out to the live center on the tailstock.
Now I'm no expert but; If the threaded end was running out when you chucked it, then the centre would bring it true by flexing the rod. Surely when you took the centre out after threading it would spring back and so still be out of true? Or isn't it critical?
Keith, I realize this isn't a casting video, but I know you do that as well. And I have a question for you about casting. Since you live in Georgia, and I do as well, have you ever tried to use the Georgia Red Clay for the molds? Seems it is very easily molded and can ever be extremely fine in granule size to offer a very smooth finished pour. Was just wondering if you have ever tried the famous Georgia Red Clay before?
I'd guess that the portion of your viewership who love to see everything in "real-time," are probably the most vocal; but I suspect the majority of us would appreciate more high-speed segments of the more tedious operations.
You talk ffaarr to much You repeat yourself 2,3 and 4 times Some things need repeating thats understandable Your videos could be shorter if you ssttoopp repeating

So, just so you know, Mr Rucker, you are 1 awesome individual. Keep at it and keep spreading the awesomeness to the rest of us. Thank You.
Nothing like a must-do job to hustle the last little details (like the threading dial).
Just think of it as your absence just makes us enjoy your videos that much more! Looking forward to meeting you at the Bash, I always like to say thanks in person. You are a good teacher!

I am thrown back by how beautiful this lathe is, never been near a lathe in my life and I love how you take care for precision.
Thanks Keith. I must say that with everything else in your life, it's amazing that you are able to keep up the great content. And remember, even the back steps are an education for us.
My friday fix. Thx Mr Rucker.

Great video Keith! I'm looking forward to seeing that 10 degree, left hand square thread being cut! Have a great time in California!
I hope we see a video on the resto for the LaBlond thread dial. You know, to make it complete. I was fascinated by the whole series.
It never fails! I often get interrupted needing to build or repair a tool or attachment in order to finish a job.
All the best!
Mike
Good Lord ... Stop apologising for being busy.
Holding down a full time job, supporting a family, volunteering at a museum, holding training classes, going to swap meets AND making quality TH-cam videos ...
Take all the time you need ... we'll wait.
Not sure the apology is intended for the youtube audience.

No way man, I DEMAND you hurry up with the free video that you er....owe me?
Yep, work and family first, I am happy with anything you bring to your channel. Top job Mr Rucker, pleasure to watch. Good camera work too...
Your a super busy man Keith ! When I see a vid up I will for sure watch it .. Take care & Thumbs up !!
Thank you Keith. Really enjoyed seeing the collet chuck in use!
Don't worry about the thread dial just leave the half nuts engaged and run the carriage back and forth. It will take a little longer but not nearly as long as reconditioning the tread dial. Nice video!

Keith you have done a nice and accurate job. Thanks.
Have a good time in California, and thanks for the video.

Nice work Keith. The LeBlond is looking very capable. Best wishes.

Welcome to the club!
Great video, and glad you can "Get 'er Done!" Oops, sorry, wrong Keith. Anyway, we'll see you next week at the Bar-Z. Jon
Great video you got to keep up your work, don't know how you do it but thanks you do.
Leaving the piece full-length makes perfect sense to me...
Step back and enjoy your beautifully restored lathe :-)
You are forgiven!, keep the videos coming.
Abom does a lot of tap with lathe or at least with drill press/vertical mill. Great job!
From a book of various versions of Murphey's Law: "Before you can do any one thing you *must* do something else first." A truism for life.
Thanks.
Progress is still progress! There is plenty in life to keep us busy. :-)
And you should know!

nice to see ya working on the Le Blonde. I would have slowed down the rpm for the HSS.
I enjoy the videos, thank you.
I have a leblond 17x72 @ 1940 my thread dial gear teeth where worn down to nubs I ended up 3D printing one in pla worked out good on third try
Perfect series :) Thanks for the work :)
You save chucking length by doing the work just like your doing. I don't think you will screw up though!!....🍁
thanks video, I'm vietnames

Would it not be possible to cut the thread without the thread dial by not disengaging the threading screw at the end and run the cutter back by reversing the lathe spindle?
I do the die's on the lathe all the time. Easier than swapping gears.
I noticed that you don't back off the cutter when returning to the beginning to make the next cut,stating the finish wasn't smooth enough. I have seen Adam Booth back out just a bit when returning to the next cut, from start to final finish cut.

Video the thread dial repair also!

We use Kurt vises at our shop every day and I noticed that the soft jaw on your vise was on backwards. The set screw faces the rear (user) rather than then fixed jaw. Maybe Kurt made some the other way but, I think that yours has been removed and replaced sdrawkcab (backwards). TW

But sometimes its nice to have an excuse so you can go relax, in which case I don't blame you for being unable to finish without the thread dial!
Didn't the nut fit/ was it loose or tight? If tight why not adjust the orginial thread?
I recall from Adam Booth's discussion of thread cutting that there are certain combinations of thread pitch and lead screw pitch that don't require use of the threading dial -- anywhere you engage the half-nut will be correct. I wonder if you're lucky enough to be at one of those "magic' combinations in this situation.
Err, I think it's any number/division on the threading dial. Not just anywhre.
Could be wrong, often am.
I think we're both saying the same thing. As I understand it, the half-nuts won't engage between divisions, so "any division" equals "anywhere". Would be nice to have an expert to confirm.
Actually, 8 TPI could probably do this. However, it still needs to get done!
Shouldn't you centre it with the stock out close to finished length? I thought it stopped the tail centre putting a bend in the part?
If you do that, you might have runout and not get the hole in the center. Better to do it chucked up close to the headstock and then move it out to the live center on the tailstock.
Tristan Patterson I agree,or, do it between centres
Now I'm no expert but;

Surely when you took the centre out after threading it would spring back and so still be out of true?
Or isn't it critical?
I agree, you must turn the finish cuts between centres , once it is straight then use chuck and centre for rigid screw cutting
whoops!!1 You will get il done.Have fun with your rebuit lathe.
Keith, I realize this isn't a casting video, but I know you do that as well. And I have a question for you about casting.

Seems it is very easily molded and can ever be extremely fine in granule size to offer a very smooth finished pour. Was just wondering if you have ever tried the famous Georgia Red Clay before?
Good job Keith. Question, did you apply a polyurethane on your walls, so it would not stain with splatter.
I applied a clear finish, but it was not poly.
Great content and editing as usual. Ho-hum. :-)
DId you get around to finishing this?
The poor guy is hanging on for it, and you've started on another restoration ( the saw) :)
shame on you for making us wait. hey, if you get time, i still need help with linking patreion to my channel. good job on the lead screw
You sure do a lot of traveling...are you in sales??
I am a tech rep where I do R&D work as well as support our sales reps when they need technical help.
I'd guess that the portion of your viewership who love to see everything in "real-time," are probably the most vocal; but I suspect the majority of us would appreciate more high-speed segments of the more tedious operations.
"I keep saying tap... We're not tapping"
So that means were Die-ing then?
You'll get tooled up and dialed in before you know it.
You talk ffaarr to much
You repeat yourself 2,3 and 4 times
Some things need repeating thats understandable
Your videos could be shorter if you ssttoopp repeating
stop blaming your inserts and use the proper speeds feeds and doc for them
seafax - rather a harsh tone there. Keith is a deity; your comments should be tempered accordingly!
seafax. Perhaps we could all be fortunate to see YOUR video showing how it ought to be done .
Grumpy bud. Real grumpy.😂
Constructive advice will make your comments valuable.
A Deity? is that like "amateur"?
