Dude. That bell can tell you when your plasma job is done, since you know, the plasma cutter will be so quiet.

[@gorak9000]

Have the plasma signal when it's done over MQTT, and attach the bell to a ESP32, and you can put the bell in the garage, and have an indication when the plasma cutter is done in the shed!

A little tip for glueing 3D printed parts; if you get the thin superglue that heats up massively and makes your fingers all dry and crusty, it will flow even in between friction fits. Just put the print together, then drip in some glue and done. If it's loose you can wiggle it a bit to help it spread, but often shouldn't need to

[@maeanderdev]

That was a hard watch for me too. How'd one even do that safely? Only option that came to my mind is to do it with two people, such that they would reach over the steel part, not putting anything below it into danger. Welder clamps as handles would probably be more reliable too

His secret: superglue 😂

[@H34...]

Having built a CNC plasma with a chain and sprocket drive, (with what looks like the same size sprocket and chain as you're using) just want to give you a heads up as to the "polygon" effect they suffer from pretty badly (the links of a chain form a polygon when wrapped around a sprocket, most noticeable with small sprockets like this). The sprocket is less a round wheel and more a multi sized polygon, so when it turns the radius at which the chain leaves changes slightly (smaller at the center of the flats, larger at the points of the polygon). This isn't super noticeable in pure X or pure Y movements, but it made the diagonals on our CNC plasma cutter kind of wiggly due to the not linear or smooth movement of the axis.

[@machinist7230]

This why everybody uses timing belts or ball screws.

[@H34...]

@@machinist7230 we later upgraded to timing belts, and then ditched them for rack and pinion. Belts are too elastic at these lengths, even the 15mm ones we used. Across the 3m travel on the long axis they also required insane tension and tended to snap somewhat often. Ball screws are very budget unfriendly and at these sizes, even less budget friendly since spinning them up to speed is jot feasible, you need to use rotating ball juts which are even more expensive. Not to mention the maintenance and lengevity nightmare of a ballscrew in this sort of environment, the dust the plasma itself generates is very fine and abrasive. Rack and pinion is the goto for large plasmas from my reading and experience. Robust, simple and effective.

[@n2fastcars635]

I wonder if you welded the chain to a piece of angle every couple of links if that wouldn't help? I have rack on mine and works well. Just a idea.

[@H34...]

@@n2fastcars635 we had the chain lying flat on a bit of box section with the sprocket riding on top just like a rack and pinion. The issues were that the sprocket very noticably climbs in and out of the chain links by a few milimeters to stay properly engaged. This is because the sprocket functions not like a circle but and x sided shape (x being the number of sprocket teeth). This results in a constantly changing driving diameter (across flats vs across points). That results in a pulsating, uneven motion. Its not terribly visible in pure x or y cuts (other than the rattling and vibration induced in the machine), but in diagonal cuts where one axis will lurch ahead, then the other. It results in a slightly wiggly diaglnal since neither axis is moving with a smooth, constant speed. Im not guessing here, ive used both chain and rack and pinion on the same machine, these are observations.

[@kdawson020279]

When I move sheet metal, it usually needs more than a magnet and my job loves to use non-magnetic metals (mag alloy, certain stainless) for security reasons (you don't want people to be able to steal $3600 street mail delivery cluster boxes with a rare earth magnet). Cleaning the shop especially under grinders and drills? Epic. I love it.

[@jeffpkamp]

The 3d case was great. That filament was the perfect color.

[@MrTimdtoolman1]

Very cool idea. We had some pick up magnets when I worked at a fastener company that picked up bolts and screws by just raising and lowering the magnet inside the housing. Cool video.

[@LanceThumping]

Looking at the Ryobi line-up, I think you'd have had a better time if you went with one of their flashlights. The small one might've let you break the top part off only and slap yours on a nicer handle with a trigger. The large one might've let you gut out only the lights and fit the magnet inside it and used almost the entire case. If you feel like making a sequel for the second one, I know that I'd be willing to watch.

[@AlexAnom420]

definitely install screws around that super glue joint and put like a thin rubber protective boot with some striations, over the electromagnet... definitely an awesome build 👍👏🫡

I love your range of skills and knowledge. This project is really cool. There are switchable magnets though, that don't require any power at all. They work by mechanically changing the magnet configuration. Are those kind of magnets not available for this task?

[@PrebleStreetRecords]

Mag tables like that for surface grinders are absolutely magic. I know it has something to do with interrupting lines of magnetic flux….but I’m pretty sure it’s just magic.

[@blazehenot2536]

as far as the shorts and break from videos goes, do what you gotta do man. your stuff is always enjoyable and fun and if you get an idea that helps you make more without stressing out then hell yeah!

[@carlnelson3893]

Excellent build, and will ring your shorts anyway... err well ya know! lol gotta do what the algorithm wants....

[@MethodicalMaker]

Awesome build! To help with the metal sliding off when your moving the sheets perpendicular to the ground, maybe add a thin bit of rubber or something to the front so that the additional friction stops the metal from sliding off. I have used neoprene foam weather stripping in the past as a cheap friction material, but that would probably be a bit thick without you redesigning recessed pockets into the case. as for the superglue... you will probably love this... hot glue in my testing is ~3x stronger in tensile strength than super glue with PLA. I got an average of 47.7 lbs/in^2 with CA glue (loctite gel), and 146.2 lbs/in^2 with hot glue (stanly dualmelt, which project farm tested to be the best, out of a ryobi hot glue gun that i let get scorching hot). My assumption is that the hot glue re-melts the PLA, and that gives it really good mechanical bonding. CA glue was stronger when dealing with shear force... so if your enclosure does crack, consider adding a lip to prevent any rotation, and then use HOTGLUE!!!

[@matthewf1979]

I can't imagine a low resistance short is good for the tool batteries, but hey, you can 3D print new ones. Right?.....right? I wonder how power it's using. Hit one lead with a clamp meter and measure the DC resistance of the coil and we can find out.

[@EddieTheH]

The low resistance isn't too big an issue because of the large inductive load.

[@weslow80]

Great idea for a fun useful project. I think if you would change the design a bit by connecting the the 2 magnetos together with a rod for a handle inbetween to distribute the weight and a t handle that came off that to counterbalance the weight, it would be much more user friendly. Would help with flexing and weight distribution. also put the battery on the t handle side. Keep up the cool projects. Also, mount the battery so it plugs in downwards to keep potential from falling out.

Put a magnet in the core, that way you don't need the battery to hold the machine in place when it's not carrying heavy stuff, a controller to add small increments of boost power, and a reverse button to cancel the magnetic field of the magnet, and some material to increase friction on the surface.
