Happens all the time. Did I plug in that BNC? Oh no ... move that
freaking heavy HP4191 back out, plug in, push it back, take pain pill
before the sciatic nerve flares up again.


Joerg, heavy test equipment should be on an equipment cart.

are some examples. Every bench at Microdyne had at least one cart. The
industrial carts they bought were just the right width for the HP
equipment, but we also used a couple pieces of 2" * 4" lumber and a
piece of plywood to use them with other equipment. A six to eight inch
gap at the front left room to store cables under the plywood. The only
time equipment had to be moved off a cart was when it went to the cal
lab. Even then, sometimes the whole cart was wheeled to the lab. If it
passed their tests, it was wheeled back. If not, that item was removed
from the stack and replaced with another piece of equipment from the
shelves of spare parts.

I use both the second and third in the list in my shop.


Those can easily tip over. I don't think OSHA would let that fly in California. Most labs are like mine. A wide bench and a rack in the back. The equipment gets shoved it that rack and you have to make sure all required connections are there.
