Hmmm... Good ideas from you all! What works for me at the moment is a
wooden bench in my garage. I made an equipment shelf for it a few years
ago. Then a couple months ago I put casters (a few bucks apiece for 275
lb ones at Harbor Freight) on the bottom after beefing up the 2 by 4 's.
Now I can move it out from the wall to get at the back. When I move
the car out of the garage, of course. Three 12-outlet power strips
(from HF, of course) on the back and about half are used.

I have a similar approach. The local "club" stores sell a metal shelf
unit, four two piece posts 1 inch in diameter, six wire shelves (try
to find the ones that are not like trays), casters, and with plastic
compression clips that allow you to space a shelf every inch
increment.

I have four of them for equipment and parts, and each one has a fitted
masonite layer on the shelf that keeps equipment feet from being
trapped in the wire shelf, (1/4 inch masonite, cheap, and the local
box store cuts it for free). On the back of one or two shelves is a
long outlet strip. On the top shelf is an under cabinet light.

Made from the remains of an IKEA table (single post design with
casters, variable height) is a U shaped workbench. The top is 1 inch
melamine (white), doubled. Reasonably sturdy. Outlet strip screwed
under the bottom of that one.

There's an extension of that which holds the soldering station,
microscope, 3D printer and desoldering equipment.

The four shelf units are arranged as a beveled corner, two against a
long wall, one beveled, and one against a wall. The units have two
shelves at bottom and somewhat above for storage. The main shelf is
at the height of the workbench.

The beveled shelf unit has no bottom shelves, and allows access behind
the shelf unit without having to move it. On that beveled shelf is a
7904, a tm5000 rack, on top of it is an HP 16702B logic analyzer,
space for a metcal soldering unit and the lab computer.

Above that shelf is another with a 7103 scope, two fluke 8040 DMMs,
and a 2430A.

Above that shelf is another with an HP 3456A voltmeter, a 4262A LCR
meter, ah HP 5316A universal counter, a Sencore LC76 capacitor
tester, and a Tek 1910 digital test pattern generator (TV).

Further than that is storage.

Each rack unit has one or two variable intensity multi-color LED strip
lights for enough illumination to be able to see controls, but not
wash out displays. Your choice of color.

Further around the room are calibration/powersupply/RF, tektronix
module storage, main LCD screen, digital scope, calibration station
for scopes, parts and project storage, etc.

It all works, but is subject to revision as I get new equipment or
work on something else.

Subject: Re: [TekScopes] how high would you stack them?

I am just finishing an exercise in cramming a lot of gear into a small
space (bench area 4' x 7', room 10' x 7'). I'm using shelving on the
double slotted standards with 2 & 3 tab brackets. In addition to the
electronics bench, I have 5 computers, 3 monitors on articulated
mounts, 2 UPSes and 2 printers. It's "cozy" ;-) Hand tools and
soldering gear are mounted on articulated monitor mounts with the
soldering station controllers on a lazy susan.

I only went 8" high mainly so I can pull an instrument without having
to disturb more than one other instrument. The shelves are about 20"
deep. I currently have HP 34401A size instruments stacked, but I found
that if I shove a 2 prong Pomona banana plug to BNC adaptor into a
34401A, the top one wants to slide around, so I'm likely to make sub
shelves for each instrument using 1/2" or 3/4" EMT standoffs and 1/4"
plywood with stop blocks glued to the plywood to keep things from
moving when plugging stuff in. My radios, soldering gear and one scope
are on 100% extension sliders so I can store them in the corners and
easily pull them out for use.

At present I only have a dozen instruments active, but I quickly ran
into a problem using regular IEC cords and power strips because of the
volume of cables. To resolve that I made a power cable out of 1/2" EMT
and handy boxes with each handy box feeding 4 instruments. It took a
couple of iterations to get it right.

If stud locations in the wall are an issue, *bolt* the shelf standards
to a piece of 3/4" plywood at convenient spacing and then screw the
plywood to the studs.

My instrument stack is only about 27" high, but that's because I have
almost 600 parts bins lined up two deep above them. The front row will
be on rails and carriages so I can slide the front row to one side to
access the rear row.

The backs of the benchtop instruments rest on the lowest shelf so the
faces of the instruments are inclined at a comfortable viewing angle.

The setup is still not complete, but it's getting there. Probes and
cables are in Pomona racks on the wall behind the door which opens
inward. I'm going to add a second set of racks to the back of the
door.

The only downside I see to this is I've spent most of a month figuring
out what to put where. And it's hard or impossible to reach things on
the top shelf without a stool even though I'm 6' 2" because the bench
is really in front of the shelves.
