That was very well explained, I had to watch twice to see the flicker on the tail stock test it wasnt even a gnats *** away!!
Good luck from Spain!!
Hi David. Thanks for watching and leaving a comment. Regards Kevin
G’day Kevin. Good job buddy. Thanks for showing us your method 👍🍻
Hi Aaron. Thanks for watching mate. Finding your feet in the new job?. Cheers kevin
Nice one Kevin. That is the way I have aligned my headstock too. I like your deflection test for the tailstock. I think last time I did this I took another pair of cuts and measured. Your way is quicker and better I think. PS. You obviously need to put a micron or tenths indicator on your Christmas list this year! Cheers, Craig
Hi Craig, I have got a tenths indicator but less than a thou on the lathes good, especially over an 8" distance.
Trouble with tenths indicators you're forever fighting the numbers.....lol.

Cool video!👌
Thanks for sharing.🙏👏👏🙏
Hi Kevin good to hear from you, enjoyed the video. Tony
Eyup Tony. Thanks for watching. You been in the shed much? Cheers kevin
@@Machine_NZNo, I've been too busy with other things. Hopefully I'll be making a start shortly. Cheers Tony
I like your idea.Will try it soon.
Hello Kevin,
Very good video, thank you... I have been doing quite a bit of turning lately and really should do some alignment tests... I have no excuses now that I know how to do it. See you on the next one.
Take care.

Hi Paul. Thanks for watching and leaving a comment. Regards kevin
Gday Kevin, thanks for sharing, I like this method, Cheers
Hi Matty. Thanks for watching. How's Trents ute, all back to normal? Cheers kevin
@@Machine_NZ still have to get a new bonnet and grill, it’s back on the road which is the main thing
Thanks a bunch man. I'm new to machining at home and it's easy to change something and not realize the effects it will have on the rest of the machine. I tore my lathe apart and replaced some braces underneath the headstock with thicker ones. Then I'm wondering why my tailstock is sitting proud and couldn't think of how to adjust it. Now I see my error so thank you.
Hi there. Glad I could be of some help. Regards Kevin
Nice to see how different people use different metodes. But all good :)
Hi Rustinox. Thanks for watching. Regards kevin

Good video mate!
Thanks for watching. Regards kevin
Good tips!
Thanks! :)

@@Machine_NZ :)
Good to see you again mate. Have you done much more with your aluminium furnace? Atb.
Hi Ricky. Thanks for watching. No I haven't done anymore melting although I do have some casting projects in the future planned. Regards kevin
I was hoping to see some actual headstock adjustment. You have the exact same lathe that I have (albeit a different brand). I’m about to do the same but was unsure of the best way to adjust it.
Hi. I didn't need to adjust the head stock as it's already running true. Thanks for watching. Regards kevin
@@Machine_NZ do you know if the headstock casting pivots on the base?
@@freestyla101 my lathes headstock has adjustment
@@Machine_NZ yes I have the same lathe. What I mean is does the headstock sit on a dowel pin or does it just sit straight on the base casting.
G'day mate what size is motor on this machine? And the rpms cheers Kevin 😊
Hi Kevin, the motors 1.5hp and 1200rpm. Regards Kevin
@Machine_NZ thanks mate I was looking at 2hp 1430rpm my motor missing info . My machine looks like your but it an Australian brand name hafco hare & Forbes. I will be watching more of your videos hopefully I will alot more about machine happy new year mate Kevin
I have the same lathe but I need to make change gears but I don't the specs to buy the right cutter. (module, dp, pressure angle etc)
I'm no expert, but all you're doing here is seeing if there's a difference in the centricity of your drill bit vs your live center - or am I missing something?
If you turn the workpiece with the live center in place, then you could measure if you have any runout - runout there would equal a need to shift the tailstock left or right.
There's a bit more to it than that. I suggest you have a read through a machinists handbook.. This is a tried and tested procedure. Thanks for watching
@@Machine_NZ
I must be missing a step...
1: you chuck up a piece of bar and take off material to make it round
2: you drill a hole using a chuck&drill bit in the tailstock
3: you put a live center in the tailstock, and adjust the tailstock so that the live center enters dead center
If you repeat that procedure, the drill bit will still center differently than the live center?!
What am I missing?? 🤔
@@Machine_NZ
Think the pieces have fallen into place :-)
1: As the diameter of the 2 parts of your bar is (very close to) identical, you know that the bar is parallel to the ways.
2: The bar being parallel to the ways, you know that the distance between the bar and the ways (with DTI mounted) should remain static.
3: DTI shows that bar is being pushed sideways ever so slightly when live center is pushed into hole made by drill bit.
This push equals a tailstock ever so little out of alignment!
Thank you sir, this made me understand what was going on - instead of just accepting it :-)
so how do you dial 90 degrees from that?
Very much different to the way I was shown, must try it myself one of these days. Thanks.
Hi Paul. Yes there's a few ways to achieve the same result. Regards kevin
what about height of the tailstock
With all due respect, I don't see a need for this process. You need a factory made half inch gauge pin that has a hole in the center. The hole must be perfect dead center. Place the gauge pin in your chuck. Then place an accurate dead center in your tailstock. Next align your tailstock into the gauge pin. When the dead center enters the hole in the gauge pin correctly your tailstock should be in perfect alignment.
Sincerely Robert
Hi there, I don't have any gauge pins..
