First all admit I'm still very much a newbie at this, but have been capable of making the parts I needed for awhile now.
After thinking I could improve the surface finish by fixing the tramming of my mill, I've been having a lot of trouble getting back to even as good as I had it.
For namesake, I'm going to call the 2 smooth bands of iron that the move-able jaw of the vise slides on as the "Bottom" of my vise.
>To start, I mount a Swiss Type Dial Indicator in a Drill Chuck and lower it deflect about 0.015" on the the Left side of the bottom of the vise and set the reading to Zero.
>Crank the hand wheel to move the DTI to the right side of my vise and take not of the reading.
>Loosen the 3 Bolts that secure the head of the mill to the Column and do my damndest to adjust 100lbs of iron to half the difference. Tighten up slightly on the bolts a bit, and move back to the Left side of the Vise.
>If there still an error in alignment, I try to adjust and go back and forth until I get an acceptable difference.
My trouble is, how can you tighten the 3 bolts without ruining your careful rotational adjustment of the Mill Head? I spent almost all night trying to get back to where I was before I gave up. I've only done this twice before, when I first got the mill and then when I got a new vise. I don't remember this being a issue before.
I do pretty simple hobby work and just want a surface I can slide my thumb smoothly over. Any advice would be greatly appreciated.
Also, I've considered purchasing a Spindle Square (the device with 2 Dial Indicators in it) that is supposed to make tramming quicker...but I imagine I would have the same problem with tightening the bolts as I'm having now. Only I'd have less hand wheel cranking to see it.
