I made some videos about tramming etc.

It's the weekend, so I finally had time to make and edit some more videos. If you're interested, check them out:

Someone mentioned in my last video post that I should break my videos up a bit into many short videos about specific subjects rather than one long video about many, so I took that to heart. I also tried voice over for the first time on the video about tramming the mill head. The audio in the first half just turned out bad, so I didn't have a choice.

How to Sweep in the Vise:

I use a tiny broom.

enjoyed the videios thanks ED

I enjoyed these, if only I had a mill with trammable head! Shims in the column are as good as I get.

The vise tramming video was good, helped me confirm I was still doing it right

Thanks for the video Stuart. Do you always take the vice off to tram the head? I've been tramming against the ways/bed of the vice. The sweep distance is shorter, but I figure that's what the parallels are sitting on.

Usually not, but I wanted to make the video about sweeping the vise in too, so I figured I'd kill a bunch of birds with one stone. I screwed up the alignment on purpose for the "Problems Caused by Not Having the Mill Head Swept In" video, took the vise off for the tramming video, figured, "Hey, let me do a short one on oiling the nuts," and then finished with the vise sweeping one.

Fun fact, purely by sheer dumb luck, when I brought the head back in line with just the degree markings after knocking it for the problems video, I swept the indicator around and was absolutely dead nuts. That has never happened before and probably never will again and I had to screw it up so I could shoot the video. Go figure.

Nice. I'm totally going to steal that for my class.

But you haven't shown the easiest way to 'tram' a mill head at all.

Is this a guessing game? I'll play. The dual-indicator setup?

Nope, the objective when your tramming is to get the quill, at exact right angles to the table, is that not what your attempting to do.

So why bother with all the B/S of try to tram the table with that sweeping rubbish.

Why not lower the quill to full extension, then just place your dial gauge on the table and raise and lower the table, adjust the head as required to achieve this result.
Once you've done the quill at 3 o'clock and got it dead-nuts spot on, then move the dial gauge to the 6 o'clock position and do it again.

Much quicker and easier than all that sweeping the table B/S with dial gauge needles bouncing all over the place.

Try it out before you go firing of an answer and then you decide which is easier.
The major problem here is that most persons never think for themselves, they just blindly follow along using methods that worked and never bother to try anything different.

Interesting. And how is this better than the sweeping process?

It does seem like there may be less possible error introduced due to the spindle rotation stuff. Have you been doing this for a long time?

Thanks,

Tramming----really --. Son, your videos are nicely done, but you really need to upgrade your subject matter. What's next, a video on floor sweeping! Please, don't waste your skills and our time.

Thanks for the observation on what stupid sheeple we all are.

hey didn't you hear, sweeping is BS? oh and rubbish.

j.bain you might do better getting your ideas across without the insults and hyperbole. Personally I see rotating the spindle as a lot easier and faster than repetitively raising and lower the table. Needle bouncing all over the place? Just use a DTI and parallel - that's the problem with people, the don't think.... . Small point, however really what we want is a perpendicular spindle axis, which may or may not be what is measured depending on clearance in the quill.

Trying different things can pay dividends, sometimes. otoh failing to recognize the reasons for, and decades of of experience leading to, convention is also foolhardy. Better than blindly just challenging convention, try to analyze and understand why its become convention. In technical matters its usually more than the idiocy of the species, but occasionally analysis leads to flashes of brilliance revealing better alternatives.

Jep, did that back when I started out as a machinist - Running the table with an indicator up and down on the quill - Easy to do on a Deckel Fp2, has powerfeed and rapid in Z-direction. Total pain to tram the head that way, the center of headrotation is so far away from the quill and the indicator, it takes forever and the actual reading on the indicator is pretty much meaningless.

On the other hand, when sweeping the table, get your reading left and right to the table, split the difference of the reading it in half by rotating the head, doublecheck, done.

Works even without insulting people on the internet
