Face mill finish

Yes, as I said in post No. 4, that's how I did it, and it's perfect. But aligning the column is not enough, you also need to align the spindle axis.

To give you an example, if you tilt the whole column 20 degrees to the right, your spindle will also tilt 20 degrees to the right because it is attached to the column, but you want to be able to tilt both independently.

You don't tram by measuring the column with a non-angle adjustable head, you tram by measuring the error with a spindle mounted indicator.

Calculate the error in parts which will result, if it's not acceptable strip the head off and scrape the dovetail to correct.
