Mounting an Ergotron LX Arm to a McMaster-Carr Machine Table

Table space is sacred when working on a project so anything that I can float via external attachment is a useful addition.

Back in 2019, my Dad and I created some Ergotron LX wall mounts with some angle iron and welding. Those mounts have been amazing and have taken a fair amount of abuse from the kids moving them around at all matter of angles.

Knowing that said mount and arm would take kid usage wear, I figured it was time to use the last one I had for the my machine table. This machine table, a McMaster-Carr steel table specifically, is not a light duty table; it’ll take a 2,000 lbs capacity. As such it’s a very used setup and floats around the darkroom and shop areas of the garage (I added a heavy caster wheel base that matches the weight rating and glides as if butter on a hot skillet) and doubles to house my Airwolf AXIOM 3D printer underneath. That table is the generic work-on-stuff table for a lot of projects and I hate giving up space valuable table space for a laptop, phone, or in some cases a scope.

Given the requirement and since I had the mount ready, I side mounted by drilling a couple holes in a leg and with just the right position of the arm placement I not only get 360 degrees of swing freedom but it’s also off the table surface edge to not interfere when I need more space.

The custom designed lx mount sits on the machine table waiting for install after a set of holes have been drilled into the machine table.

A few bolts and washers later, and we’re mounted to the table.

In practice this has worked out quite lovely the last few months. I can be working on a project, fire up a stream without issue, and it all just wheels around without any effort required. Sometimes, it’s the simple upgrades that make working on a project not only easier, but enjoyable.
