Double indicator arm really helps tramming this kind of milling machines. Same procedure, first make the sideways rotation straight and zero the indicators. Now the tilt with the offset pivot point is much easier. Turn the head until both indicators show exactly same value.
Excellent Video! What about squaring the x-y table to the machine? In other words, how do you assure that the x-travel and y-travel at one extreme is the same at the other extreme?
If you're mounting something to the table itself then this is exactly how I'd do it but if your mounting a vise then I always tram the machine to the vise itself.
6:20 the machine has notches on the quill housing(above and below the depth screw) to use a square specifically for that setting. You don't have to use the quill like that. Likewise the same notches are used to set the nod too.
Nice to see that good old machinist know it all attitude in the comments. “Its not vernier” “i do it this way so this guy is wrong I’m better” Shit never ends.
I swing 20” and indicate 3 points’ 3-6-9 o’clock on the table. The table is 10” in Y. This gets you closer than splitting hairs in that radius. Once you have zero on all three points, your dialed 👌🏻 Old guy turned me on to this.
The red flag warning was in the beginning when you were leaning on the machine. Fully extend the quill. Why? To magnify the error from tilt vertex. Then proceed with a precision parallel. No need for that ring ding. Pay attention or pay cash!
Very true, the quill should be extended out for maximum accuracy. The nomenclature needs a bit of attention. There are no Vernier scales, just scales. The combination square has no ruler it is called a rule. - It is engraved to the ends. There are no rack and pinions, they are worm drives. The forward tilt is called the nod.
2:14 " so you can see there's a vernier scale for both dimensions" Nope, I can't see a vernier scale on either BECAUSE THERE ISN'T ONE. How did you get the job ?
I suppose for a technical college, that's good enough. Any students going on into the real world can learn later how to do it professionally - and using the correct tool.
The tramming ring speeds up the process and makes it easy. Thank you.
Great job on the video totally informative.
Thanks! Nice set up procedure
Matt, you make the best videos on this channel, Thanks. I’ve learned something on everyone that I’ve seen.

Yup.... PM would do well to watch ol Mr. Pete, the youtube shop teacher!

I think he ensured that by using the 360 degree ring. Any error in that would magnify over length. No error, no magnification over length.
Excellent instructions, thanks man...
Very well done and explained

Amen!
What if you don't have the ring? Four equal blocks?
Great info
Awesome thank you

The head can rotate(see the large scale beneath the "e mill"). You have to run the indicator in x along the entire ways of the milling table too.
Do you really? I’ve never heard this before not doubting you. Just want to know in college now for machining

5:26 the scales are not 'vernier dials' either !
Wait a minute, this wasn't a cat video!
2:14 "
so you can see there's a vernier scale for both dimensions"
Nope, I can't see a vernier scale on either BECAUSE THERE ISN'T ONE. How did you get the job ?
5:14 "I'm going to use this combination square head"
'Combination square' - I'll agree with but not the 'head' part.
Yeah really, use an indicator 1/4 in collar extension and JUST USE THE TABLE
😅 come on man,
7:03 They ARE NOT vernier scales !

Good info. Thanks for the look.
