quickly saw how things needed to
I then designed a simple fixed
mount bracket that would work for
both the front- and side-mount
lasers. This bracket is detailed in
Figure 4. The drawings are in
hybrid English and Metric
measurement schemes, as I kept
going back and forth from
extracting measurements off my
Chinese made mill (Metric) while
trying to be compatible to the rest
of my shop (English).
The brackets are designed to
be attached to the spindle
enclosure using small 4-40
hardware into holes drilled (#43)
and tapped ( 4-40) into the spindle
housing. Note that the mounting
holes in the brackets themselves are
intentionally over-sized for 4-40
hardware, so washers are required.
This was done to provide some X-Y
as well as rotational play to the
bracket so that laser setup and
alignment would be easy.
Before any drilling and tapping,
I suggest that you power-up the lasers and then temporarily
attach them to the spindle housing using double-sided foam
tape. With this approach, I was then able to perform some
preliminary alignment steps to insure the lasers were
located properly with respect to the center line of the
spindle, and that they were perpendicular to the table. I
developed a set of alignment steps that seemed to work
pretty well (see the section on Alignment and Setup).
