I have spent hours and hours a day in the last few weeks, just watching your videos. Some more than once and still learn something new every time. Thank you for posting!
Really love your instruction and my wife often watches because of your no-nonsense approach and honesty. My question has to do with running the spindle slower while indicating. At 14:42 the indicator shows more swing as the spindle comes to a stop. If run slower, might the centrifugal strains and possible vibration not be so affecting of the indicator movement? Thank you again for the great work.
thanks again mrpete most interesting as always.. take care sir from the uk.. will there be a video on the spring winder I would like to see how it works..
Very well done. I wonder what would happen if you turned that rotary table through 360 degrees with the co-axial in place. then you'd see the run-out in the rotary table. When mounting your 3 jaw you might be able to take that out. Assuming it is worth messing with given the project at hand.
Lyle I know this is an old video, but wondered why you were using the Co-AX on the same plug you used with the collet for centering? If the plug has slop, that slop is still there when using the Co-Ax, Would think that something like a Morse taper arbor with it's snug fit would be a better choice for use with the Co-Ax (or a Last word or any other precise measuring method) John
Hi Lyle Just bought one of the axial indicators and after paying for shipping they ar $155 into Canada and then there is still customs. About twice the advertised price. Allister Denyer
Love your work, but why would you need to run the spindle at all? Seems you would be more efficient if you simply turned the spindle by hand. The speed is great for showing off the co-ax but not required. Thanks again, Hiram.
I have picked up a skf k1031616 lathe tool and haven't been able to find the insert that fits in it, are you familiar with this tool, can you tell me what inserts/tools fit in the k1031616 tool
I have a coaxial indicator and run it at 200 rpm or so. That's no so scary. One more thing to check is if the center of the rotary table is concentric with it's own center, crank it and see.
Hello thank you very much for yet an other excellent video! It might sound like nitpicking, but to be really accurate wouldn't it be necessary to center the position of your reference pin relative to the rotary table with an indicator first? You could do this in a similar manner as you would indicate a workpiece in a four yaw chuck, i.e. use an indicator fixed on the mill table, rotate the table and move the reference pin until the indicator doesn't move any more. Kind regards Harald

Great video as usual Mr Pete but Wow....650rpm!!! You may want to walk that one back to maybe 65 rpm 😉. If the machine wont go that slow Id drop it in neutral and rotate by hand.
Give me an Indicol and a .0005 in test indicator (I have had a Besttest for decades) and I can have the table on axis faster than you can set-up tu coaxial.
It seems to me that you only centered the top surface of the rotary table with respect to the rotational axis of the spindle. You did not appear to attempt to verify that you had centered the rotational axis of the rotary table with that of the spindle. Seems to me there could easily be more than several thousandths difference between the RT Axis and the RT Surface, especially if the RT had been used hard and had been beaten up a bit (or the worm gears were a little loose).
No...because the bottom surface of the rotary table is perpendicular to the axis of rotation (especially on older quality Palmgren -- assuming it is not beaten up) and the rotary table is bolted to the table of the mill which has already been trammed in (meaning z axis of the mill is perpendicular to both x and y mill table axis -- see Pt 1, he mentions his table is perpendicular: "trammed" ). Therefore the rotary table's axis of rotation is parallel to the axis of the spindle. Not to mention this method & description is NOT ABOUT "how to center old beat up, abused, and catywampus rotary tables on the mill". Start thinking.

Fantastic tutorial! Even when I have done this a couple of times, I learnt quite a lot. Thanks for putting it together!
+CNC Dude Thanks for watching.
I would like to thank you for taking the time to teach us nubies so much more than machining from all my heart I thank you sir !!!
+gizzo123us Thanks for watching.
Fantastic! just like all your other videos MrPete Thank You for your Time & Effort and all the hard work it is VERY much APPREICATED!!
+Rosario W Thanks for watching.
Only on this channel are they making word play with Toulouse Lautrec. Good for you Lyle . Keep em coming. S'il vous plait!

As usual with your videos, interesting, informative and well presented.
Thanks

+larrysbk Thanks for watching.--good one
Mr Pete that indicator is running like crazy it creates lots of vibrations,I have one and I only use it at 50 RPM it's more than enough!!!
+John Hili Thanks for watching.true
Hi mrpete,
Great inventory in way to setup a rotary table on a mill, well done like always, insisting on the important details...

Jut bought one of these 8 inch palmgren tables for $100! Super happy
what does the axis offset printed on the face of the coax indicator mean?

Always informative. Thanks
+Robert Patoine Thanks for watching.
Why to move the table to remove tha indicator and not to up the shaft chuck with indicator in it ????..
Thank you Tubalcain!,,, in depth and easy to follow! :o)
O,,,
+Opinionator52 Thanks for watching.
I have picked up a skf k1031616 lathe tool and haven't been able to find the insert
that fits in it, are you familiar with this tool, can you tell me what inserts/tools
fit in the k1031616 tool
Sorry Jim--my knowledge on carbide is a little lacking
thank you again mrpete222
+stevenacarter77 Thanks for watching.
At work in my VMC I run my coaxial indicator at 50 rpm. 660 like you did seems way too fast. All you see is a blur of the needle.
+Matthew Diaz Thanks for watching. yes
Mr. Pete slow down the RPM's, to fast for a coaxial indicator. Using it at slower rpm will make it easier to zero it out. Great videos.
+40cleco Thanks for watching.

great job....your the best.

got to do this when I get home off the ship

Mr. Morse?? OK, I guess I'll get the answer in a few minutes while I watch the rest of the video.
Update: I wasn't even close!

Thx
I would guess James Maudsley who invented the screw machine lathe.
You don't, but I didn't. ;D
+Richard Freeze Thanks for watching.-yes
Way to fast for a coax indicator.
+Damo Floyd I agree, far too fast.
+Damo Floyd Nope, he kept it under the max allowed.
its Henry Maudslay
+MrMadazhell yes
Too Loose-Lautrec lol.
John Strange" Three Jaw Buck" and Too-Loose La Trick...sounds like characters from an old 1930s movie with Humphrey Bogart.
