Thanks for the info. Unfortunately, while this a great tutorial on the basic way to bring an out of line tailstock back in, everyone wants instead to highlight all the other problems found when checking out a lathe. This video is not about correcting all problems found on a new-to-you lathe. It’s about bringing the tail shaft back to center after taper turning, etc. At some point we must assume the other checks are okay, that the lathe is level, the bearings are good, the taper is okay in the tailstock, and on and on. The information given here is useful on its own and is exactly what the title describes.
There are some problems: to make shure that the indicator is always in the middle of the test bar you must check the height of the tailstock, check if the bed ways are straight and not worn out and last but not least if the result of the indicator also is the same in every position of the tailstock quill.
I have a 1956 13" south bend lathe ,Does anyone happen to have the spindle nose cone that I believe allows you to put a center in it to allow to turn between centers ? the chuck end spindle bore size is 1.616" in diameter the far left side opening is 1.412" spindle diameter approximately 2 1/2" into chuck end of spindle is 1.515" and overall length of spindle bore is 21"
Always remember, nothing will destroy a tailstock faster than, errent chips entering the taper of the tailstock quil, spinning drills in the quil, using drills, chucks, and centers with damaged tapers . Once this taper is chewed, it's nearly impossible to correct to it original shape. I seen too many tailstocks with this damage.
@@mikem970 How are you going to do this on a super-precision lathe? Sometimes the shim needs to be 1 micron in thickness. Aside from that. What about orientation adjustment?
Precision Matthews lathes and mills made in Taiwan are superior to those manufactured in China. They sell ones made in both countries. The ones made in Taiwan have the letter T in their model number.
OMG has that lathe been abused or what , the compound slide is chewed up worse than I have ever seen , This is catastrophic for the machine slides and spindle bearings after being run into the chuck that many times
I wanted to watch this, but the music that plays over the narration is awful. Why would you put that on so it makes his voice harder to hear ? Just skip that.
You do an incredible job teaching! Simple and straight to the point only, with all common sense explanation. Please keep up this amazing channel.
What if the tailstock is out of alignment vertically? Would the roundness of the test bar indicate that when only measuring on the side?
Excellent presentation!

TURN OFF the MUSIC when talking starts.......!!
Anyone who adds emotionally demanding music to a factual video has absolutely no clue about music.
Excelente trabajo, saludos.

What about the height and orientation of the tailstock? Do those have to be adjusted?
Should verify the vertical alignment first
Thanks, great video, it really helps a lot

I agree, what about vertically?

Thank you very much.
What about the up and down alignment?
Had to put a shim under the front and back of mine .

That’s true, but I just need mine to be within.001 ! I use a boring bar for tight stuff.
Great video. I'm wondering if you know what brand is a good home hobbyists lathe to buy? Maybe an 8×16
I love my Grizzly G0768
Some say that precision Matthews is the best quality controlled of the chinese ones

Take the lesson.
Great music.
