I like it a lot. I agree on the casters from medical equipment – I’ve spent a fair amount of time in doctor’s offices and hospitals in recent years, and noticed them on carts, gurneys and so forth They run very smooth and are designed to hold a lot of weight. In fact, many medical facilities use a roll around cart that could be repurposed in its entirety; they have multiple drawers, a rubber bumper around the perimeter that would be good for avoiding bumps into your car, and are extremely rugged. Some of them have provisions for mounting a computer, monitor and keyboard. I suppose you could check around for places that sell used office equipment or medical equipment, they may have some of them for sale. Medical offices also have really nice stools with an adjustable height padded seat, I’d like to have one of those for garage work. They typically have five legs so they’re very stable and don’t wobble.

An upgrade to the design may be to get your hands on a Luxo magnifier light – they have a circular bulb around the magnifier that puts out a nice amount of light (they used to be fluorescents, I imagine they’ve switched to LED by now.) I have a couple of them, and the magnifier is real handy if you’re working on things like carburetors that are full of small parts. (they do run on 120vac so they’d have to be plugged into the bench inverter.) They are still available new but are expensive – I managed to find mine for reasonable prices at yard sales.

I could see where changing the height may be beneficial to some people, depending on how tall they are. Working bent over a work surface that’s too low can be a literal pain in the neck.

I grew up in hospitals, and a lot of the inspiration for this mobile bench came straight from the carts I saw rolling around those sterile hallways. The casters are killer—not just because they’re rated to carry the weight of a small planet, but because they’ll roll over damn near anything without flinching.

And yeah, a Luxo light would be fantastic—no argument there. But I ended up going with a video light, mostly because of the 1/4-20 threads. I needed something that could collapse behind the bench thanks to some height constraints, and short of fabricating a custom setup, the mic stand I already had fit the bill perfectly.

That… and the light is blindingly bright. Like, make-your-eyes-sweat bright.

Huge thanks for sharing this, super helpful!

Gonna pick up one of those packs on Amazon and give it a go. If my soldering doesn’t look too crappy, I might post on here for others to see how it all get’s rigged up.

It’s a super easy soldering job. Just two spades… and they are large… I’ll see if I have video of that.

The battery side adapter I have a good print for, its the side that attaches to the inverter where I am a bit lost. It looks like you have your wire running into one of those generic "build-your-own" M18 battery cases, so is that wired into the PCB somehow and then you mount that to your 3D print? The M18 diagram shows tabs for intermediate voltages, so curious how you got the pos/neg from the custom adapter to play nicely going into the inverter. Any light you can shed would be appreciated.

BTW, your entire cart is cause for envy, it’s just I have a use for the clever remote battery part for a project of my own at the moment.

Gridfinity has also changed my life for the better (and my wife’s but she doesn’t know what it is called, just that our entire kitchen is so well organized now…), super cool to see it in use in your shop too.

Keep up the inspiring work!

Yes! I totally forgot about using half a fake m18 battery case. This thing went together almost 2 years ago… I believe I have all the details in my shop. I’ll dig em out tomorrow.

I think it would be fairly easy to fab one 1-1/2" DOM tubing is easy to get, another with that ID, and plate with a hole in it…

I don’t currently have a suitable bench for that, or I’d ahve made one, but there is is..

I got this pic from somewhere… Would be perfect on my little mobile bench:

Can you provide more details on the remote battery connection? I assume it is a 3D printed part on both ends, with the wiring simply moving the current from the battery to the inverter – was that a custom design or did you purchase it? I would love to replicate that function but a bit lost on how that wiring was done.

Thanks!

Yes, 3D printed both parts – one for the battery and the other for the inverter. That’s the one STL I can’t give out… I don’t wanna be held accountable if someone burns their house down.

BUT, I think people sell the same kind of thing on Etsy…

Cool project Ryan!

What would be perfect for the Versa-Vise is the pop up flush bench mount for the base. Rare and hard to find.

I’ve been looking for one for over a year… I’d love to have one.
