The concept I had was to mount the vise to a flat surface of a size
TBD based on needs for use of the vise. If the vise can't be used,
there's no point in having it at all. The flat surface would be
mounted to the CMU wall via the anchorage scheme I had previously
outlined.
The size and shape of the mounting would also depend in no small part
on what it's being mounted to. I can get a couple of hundred pounds
per anchor out of an anchor in grouted CMU. If the CMU is ungrouted,
the anchorage will withstand substantially less demand. I still do
not know how much clear space is needed around the vise in order to
make it usable. If it requires >= 3 feet clear on all sides, mounting
the vise to a wall-mounted table is a non-starter. There's no
practical way to make it less in-the-way than it already is. The
table would stick out from the wall >= 3 feet.
Regarding a table-sized mount, that wasn't necessarily what I had in
mind, insofar as I had visions of using saw horses to support the
remainder of whatever part is mounted in the vise. This function is
(presumably) filled by the tabletop to which the vise is currently
mounted. However, I don't know how much clearance is required to use
the vise. It might not be practical to mount it to the wall.

All of these issues are valid points that need to be raised. I am not
licensed to practice engineering in Massachusetts, and the 'Tute may
want a Massachusetts licensed engineer to review and stamp whatever
design is arrived at. I know the design I offer would meet the
requirements, but the folks who own the building get to make the
rules.
I would need some degree of access to the plans (or contact with a
brother who can read plans and take digital photos) in order to
evaluate the safety of the attachment.

One key issue in this discussion that needs to be considered by the
Chapter is the continued use of the press. If AX is still interested
in maintaining printing as a service, there are certain maintenance
needs for the press hardware. That means that, although the press
shop may spill into space beyond the idealized vision of what it
should occupy, that may be space that's necessary in order to continue
offering the service of direct-impression printing. I don't know
enough about this maintenance issue because that is clue I never
really got. Len has done that type of maintenance since before I was
an active.
For the record, I am not advocating one position over another. Y'all
are actives and I am mold. The primary function of mold (IMHO) is the
provide a "clue repository" since the average memory lifespan in
actives tops out at ~ 4 years. There may be some grad student actives
who are around longer, and some brothers on the 5 year plan. However,
the chapter to some extent depends on mold to assist in providing
continuity of clue, not day-to-day advocacy on issues. That said,
major decisions that impact AX's ability to continue offering a given
service sometimes warrant unsolicited opinion from mold. The few
times I got unsolicited advice from mold (as SVP & President), I
thought hard about it because I knew it wasn't offered without a lot
of consideration by the brother in question.
Another thing that might be easily overlooked by folks who don't
actually know me is that I am old mold (1C Class of 1997) and live in
California. As a result I know nothing about what the current
APOffice configuration is. I demonstrated that (in private exchanges
with Len regarding potential design parameters) by discussing whether
or not the vise could be mounted along the wall where "the coke
machine and food cabinet are located". Len informs me that the coke
machine is long gone, and the food cabinet moved to a new home quite
some time ago. The moral of this story is "Don't bank on Charley
having any idea what the office looks like." I know it has two
masonry walls and two walls of windows. I know there's a masonry
(probably structural) wall that separates the front and back offices.
That's about what I know about current office configuration. ;-)
