TAILSTOCK ALIGNMENT on LOGAN HARDINGE South Bend Lathes Part 2

[klixxie]

Thank you my friend from across the pond, for an excellent tutorial.

[psarantis]

How many deegres turn the compound and why do this?

Please reply because no one know .

[Topstrap44]

I noticed that when you rotated it 90deg that when it was on top it showed the quill was higher. It also showed that on the spindle. I've found that same thing on mine and have been wondering if that needs to be addressed or is it not as important as it is on the horizontal plane?

Been watching all your videos and have learned so much, many thanks for all your hard work.

Love your videos! They help tremendously.

[joeygonzo]

Thanks Pete.

I did this trick but with the indicator on it's round base chucked up.

I found out my tailstock points up a little.

[Films4You]

looks like the second method will not be subject to carrage errors, so could be the best method to use, as well saving some money

[autofrite]

Thanks,heading out to check my tailstock.my brother in law-retired machinist just passed on an armload of measuring tools.im confident its close,but i want to know for my own peace of mind.every video so far has given me confidence to operate my lathe safely and with some level of accuracy.

Just used this method on my 12# Logan. Worked like a charm! Thanks Mr. Pete

[makedoandmend2]

I found the two key method mentioned to be vital advice. I put a very strong magnetic stand directly onto the side face of the lathe chuck which seems to work okay. Because the tailstocks on my harrison 600 series lathes cannot be adjusted until the hold down clamps are slackened I had to double check the readings again then make some minor adjustments . A old lathe might give a slightly different reading when the tailstock is moved to the other end of the lathe bed.

[toddclites]

Great instructional videon,I hope you can tell me how to canter my tail stock on my 7X10 mini lathe.This is my first lathe and Ive never used one befor I bought this but I quiclky found the tailstock to be out of alignment. I marked center on a round stock of stainlesss steel and the tip of the live cenceter is at least 1/32 of INCH!! and the are no alignment marks. Well I hopw you can help me out.

It turns out that my friend was a star student of your dads at LP. He graduated in 1963 and then went on to be a shop teacher himself. He was on of the best teachers I ever had and is still teaching me to this day. (and I just turned 50 years old). He is very much like you: He wants to pass on all that knowledge in his head before "old time machining skills" and knowledge are a thing of the past.

[mrpete222]

@John91406 The story you are telling is familiar. My brother is apparently acquainted with this man & has been in his shop ---seen the engine & the picture. My dad had a half completed Corliss when he died in 1966.

[John91406]

It Anyways, He has an 8x10 framed photo of your dad mounted on the wall behind his lathe. When I asked him who and why the photo was there, he said (with a certain amount of reverence) "Mr P. watches over me to make sure I don't screw anything up"

[John91406]

Hi LP,

Small world!

My Jr. high school metal shop teacher became a close personal friend of mine and taught me a tremendous amount about all things metalworking over the years. He is an exceptional machinist who recently completed a Corliss (sp?) steam engine that is nothing short of a work of art.

Great Videos! Thanks for teaching.

By any chance was your dad Norm P. who taught in Olgasby (Spelling?) Illinois?.

[mrpete222]

@John91406 Hi--Yes, Norman was my dad.  He taught shop at LP high school for 30 years.

I will search out for an atlas 12". I am newly learning to lathe and lathe working. I learned so much by just watching your videos. Its really nice to see that you are sharing all your knowledge and skills for other to learn. I was hoping you can do more videos using your atlas lathe. If ever you may have the time, could you do a video on how would you fully thread a 36" 3/8 brass rod using a 8 thread.

Thanks for all and God bless

Thanks you for your time and God Bless always.

[LG6327]

hello, is there a index live center tool with even and odd number settings which can be installed in a 3 chuck or tail stock on metal lathe with the head stock in a locked position that i can manually rotate a dowel so i can make even and odd number of grooves?

[mrpete222]

@LG6327 No such thing to my knowledge.. However, if you have an atlas 12" lathe, there is a built in indexing system. The face of the front spindle gear has 60 evenly spaced holes. There is a sliding pin that engages a hole. In this way, you can divide a circle into most any number of divisions.

[jlg4880]

A wooden indicator holder--That's...Brilliant!!!

But I have one stupid question: If you're using three-jaw universal chuck, how do you know if the path described by the 1" or 1-1/4" radii holes are concentric with the spindle rotation?

[mrpete222]

@jlg4880 Concentric just like a dividers or compass

[aaguss97]

hola te invito que visites algunos de mis vídeos sobre una pequeña metalurgia en argentina gracias

[ihearvoices22]

this is a very simple method. i do some custom gunsmithing in my dads machine shop and one of the most difficult things i find sometimes is dialing things in. sometimes i have to think for a minute to figure out where and how to use the indicator to get the result i want.

[bob2020rs]

Thank you! You are the man! I have learned so much from your videos. Your teaching style is GREAT!

[kavaldzhia]

I've been a tool and die maker, working mostly on our shop's 1992 Monarch 10 EE lathe and others before it, for over forty years ... this is a very practical approach, thank you for sharing !

[ahz123]

I used this method tonight. Worked like a champ.

[CncObsession]

Mr. Pete, Thanks again for a great instructional video. I immediately went and centered mine after watching this. A used a variation of your technique. I used a mighty mag and a DTI. I installed it on the face of the chuck and slid the magnet til the indicator touched the dead center, and like you I confirmed the spindle of the tailstock was concentric. It got rid of that pesky wobble of the drill bit as it enters. Thanks.

[MGARestoration]

Thank you yet again for broadening my knowledge of metal working. Keep em comming...

[Palmaa2009]

Great. You have creeated an interesting method using mesurement apropriated. Thank for the video. Aurelio- Brazil

[Metalloys]

Certified Genius. Thanks a million.

[rlewis1946]

What an ingenious setup and clear explanation! I really enjoy the way you effortlessly narrate these videos. For an old guy like me who's trying to learn some new tricks, your videos have been wonderful! Thank you and best wishes, Roy Lewis ATL, GA USA

[joeygonzo]

BRILLIANT!!!

[kw757]

That works to get the left and right adjustment correct, but what if it reads .000" on both the left and right sides, but reads, say, .004" when the indicator is at the top of the tailstock center? Is there a way to adjust the tailstock to fix vertical misalignment as well, or not? Just a hypothetical question. Thanks!

[StMichaelsCrew]

I want to make one of these expensive wooden holders for an indicator. I have a 9in. S.B. would the measurment from the center out be the same for my lathe? That would be the 1in. hole and the 1 1/4 hole. Thank you for sharing these pricless video's. I can not tell you how much they've helped me. Thanks again.

[mrpete222]

@StMichaelsCrew Thanks for your support. Yes--make it with those dimensions. You can also drill additional holes if necessary.

[RWCSNZ]

Hi, its great to see your videos. I have your book Milling Operations in the Lathe as part of the Workshop practice series - Its reassuring to see it done on video.

I have noticed My tailstock is a little bit too high, it's fine side to side, can you forsee any problems with accuracy on any application?

[Angusinwyoming]

Thanks for all of your videos. I have learned a ton by watching and using them. Angus in Wyoming (I'm just over the mountain from your brother in Cody).

[mrpete222]

Thanks for the encouragement.

[yakuzalou]

Mr pete

I have the same lathe, and I was wondering if you had any thoughts on the veri drive conversion .. Im getting some wobble 3/8 threaded rod that holds the valve onto the disks...i read that some wobble is fine - less then 1/8" .. but I have more that that.. any thoughts...

and since most of these lathes have similar drive issues, what about a video of the maintainance.

thanks

[mrpete222]

Never had any problems with drive--therefore know nothing about them.

[sirlancair]

Just bought a south bend 10k and am enjoying your well thought out and explained instructionals.

I hope you continue. It's just what I have been looking for. Thanks a bunch!

[alehax27]

Have you used a coaxial indicator to center the tailstock?

[mrpete222]

No--I do not have one.

[sginker]

Coaxial indicators have considerable indicator droop and will cause inaccurate reading if not held in the vertical direction.

[gohuskies583]

Great idea! You are very good at explaining in all your videos, it shows that you were an excellent teacher!

[dollzballz]

These videos are excellent. I have used a bunch of your methods to set up my machines.

[cdbflynow]

Very clever approach - Thanks for sharing.

For those not inclined to cutting out a cylinder of wood, they can make a triangle out of the 2x4 with two straight cuts , tighten it in the chuck and drill their hole to hold the indicator. Give your brother a gold star.

[jfco61]

Mr. Pete; I had a round indicator, for long time, now I am going to use it ,

[chickenfarmer922]

Thanks for your usual good instructional. I see you are using a self centering chuck. This would also test the concentricity of the chuck too would it not? If you are unable to adjust using this method the chuck could be out of center. How would you go about fixing a non-concentric chuck? Maybe a toolpost grinder on the jaws?

[mrpete222]

The chuck has nothing to do with accuracy on this procedure because as you can see, I am not holding the indicator on center in the chuck.
