I should point out that the plasma cutting I did in this video is 80% of the plasmaing I've ever done, so I'm no expert! Also yes, I will be replacing the plastic hoses with metal ones
Maybe add a vortex slag droplet catcher? I hear there was a video out there where a woodworking one was made . . . Although since metal is heavy it probably only needs a simple single stage.
This is the first time I've seen some real innovation on a CNC machine. Don't get me wrong, traditional CNCs are great, but mostly for production work. Draw once, produce hundreds, thousands, millions of times. For a hobby shop, where you mostly make things once, the trace functionality of this machine is freaking awesome.
better yet, I've seen these cutters that can follow a track drawn on the workpiece...maybe on a water jet, but on plasma, it could follow the track, "cold", record the travel, then cut...
I wish I owned a company that made stuff so I could send the device to you for free. Your "not sponsored but sent to me" reviews are way more convincing than other people's paid sponsorships.
13:23 a feature that i once have seen on a cutting table, is to place the baffles diagonally. That way when you make a straight cut in the width direction, the chance for mangle up a entire baffle is much lower. Depending on the amount of usage, it can be helpfull to make the baffles with fixed pins that fits in a hole on the bottom, that way baffles can be replaced very easy if they are mangled up after many use. Another suggestion is to use at the hose at the floor a T on it's side or a square box, with the hose connected on the side, that way small pieces of metal get trapped there, and will not be sucked in the fan blower. Sort like a wood dust extraction system works.
When I was in high school shop class, we had a TorchMate plasma table, I think the thing was in 5 digits and needed two control boxes, a special torch, and expensive CNC software to work. I'm fairly certain it also ran on 440. How far technology has come!
I have three phase 400V at home, seriously this house was build in 1971 and this is the original feed. Why the US still runs on 120/240 is a mystery to me.
@@patrickd9551 Because otherwise we will have to run 120/240 AND whatever new system they come up with? After all almost every home is already 120/240.
@@patrickd9551 Alot of european 120v infrastructure was destroyed in ww2 and when they rebuilt, they upgraded. Obviously that never happened in America.
I don't know what any of that means, but I had to opportunity to use (and clean) a plasma cutter in my senior year of HS. Inch thick baked on mate of steel under two inches of partially baked on steel dust. But the many times I used it were fun.
Listening to the downdraft table discussion got me thinking: what if you added a "fume hood" over the top (maybe with a fan similar to the exhaust fan?) that would bring in outside air while the downdraft table was on, that way the "negative pressure" outside air would be pulled in right over the downdraft table, instead of through doors and windows throughout the garage?
For as much as he’s probably going to use the cutter it wouldn’t be worth the time. Also the negative pressure would be inside the building by the downdraft table hence why the higher pressure of the ambient air would go in.
I am massively impressed and slightly envious. Also consider googly eyes for the arm, for one glorious moment I thought you'd done this, but it was my pareidolia seeing them in the bolts and washers instead
My wager is that the plastic housing for those safety feature contact points just gave way due to heat deformation over time. Failing in the middle of a cut would be inevitable under that premise. LOVE your content, btw! 😁😂
The other reason I could see it failing during a cut would be some issue with insufficient slack in those cords being tugged around somewhere upstream as the head is moving.

For the downdraft: you could also provide the fan with fresh air from the outside. so like, outside air is fed above the table, and then fumed bad air is sucked out the bottom. Essentially, that sucking fan is going to pull outside air into your shop, *and there is no way around it* (if it didn't pull outside air, you'd have a warehouse at less than atmospheric pressure). What I'm suggesting is this: instead of the sucking fan bringing outside air in from "wherever," give it a suck or origin. You can put like a door or something over the input hole so you don't lose all the conditioned air.
It's crazy that I wait until I'm alone in the middle of the night to watch your videos so no one can fking bother me. Guys like you and Peter Brown are treats to watch.
Nice build, man. Glad you are taking the fumes seriously. That machine is pretty neat, too. (Although with an MSRP of $2500 it better be) Noticed what I think is a Wyse camera on your shop wall. If it is and you haven't seen the security vulnerability for those yet, check it out.
@@GrayRaceCat Generally if I post links my comments get removed. Google "wyze camera vulnerability" and it should point toward articles around spring 2022 about the issue.
i dont normally comment on these videos. but i have to say that you are one of the more entertaining content producers. i also like the fact that, "mistakes were made and here they are" aspect. and as one last point, the fact that it looks like you actually use your shop is refreshing.
You've got to be my favorite RUclipsr.. the content you cover is interesting to me but even if it wasn't, I would still watch because you have a hilarious personality and sense of humor. Keep 'em coming!
A downdraft is the most important addition to a plasma table; my shop was FILTHY after a couple years of running without one, and the dust is ferrous so it is magnetically attracted to motors, computers and settle in and everywhere. In my experience the sparks are out after about 4' so you may want to make a 'trap' by bending your hose strongly upwards so heavier particles can settle in the 'dip', similar to a drip bend in exterior electrical lines. All in all, a nice project. You should just draw in an external program for an accurate DXF, and then set your zero reference to a known position on the stock, say lower LH. Also put weights on your stock to prevent movement, but make sure of torch clearance; for small parts, overlay the corners with larger sheets that you CAN put weights on, to pin down the corners.
Earlier today I thought to myself, “I haven’t seen an Under Dunn video in a bit. Wonder when he’ll get around to another video.” I then saw this video tonight. Thank you for reading my mind.
I really hope that "just dealing with the fumes in the shop" meant you were wearing an appropriate respirator, like a half mask N99 or something. Edit: oh good! Just got to the point where you said you are. Nice! I also really recommend wearing both gloves when welding and cutting. I know it makes you less dexterous, but the amount of UV light coming off the torch and welder is no joke in terms of long term skin cancer avoidance. I know this can sound like internet comment safety expert bullshit, but I'm literally a shop safety expert. Teaching people (adults and children) to safely use tools of all kinds was my job for nearly 8 years before I switched to teaching math. This plasma cutter is cool! I love the mechanism! It's interesting to see the alternative to a gantry system, and the ability to use it for coordinate measuring is seriously awesome.
Just chiming in, when welding, even tacking, at minimum wear long sleeves and gloves; once I had what I considered a short session, but the next day my forearms were 'sunburned'; as mentioned above, the arc creates nasty radiation, both visible and invisible.
In my world, plasma cutter wins over sheet metal shear every.....single.....time! For no particular technical reason. Thank you for the information and technique, and foible sharing!
some pretty decent editing skills you got there! (a sentence I thought would never come out of my keyboard) ;) Awesome clip. Love your sense of humor. Great work!
I wish I lived by you so I could always hang out there, even after you left. You have a lot of tools I wish I had. I really love my Thermal Dynamics Cutmaster... 50? I forget the model number.
Did you seriously just try to fix a plasma cutter head with HOT GLUE!?! I can't decide if you were trolling us or if you genuinely said: "You know what, let's try it! What's the worst that could happen!"
Due the passing air at high speed, the torch doesn't get that hot at all where the hot glue was added. Also the blue insulation on those thin wires have not much higher temperature rating as the hotglue itself. it depends on the cutter itself, some keep air blowing for a short period of time after you released the button, to cool down the brass cup.
We had a big 5'x10' downdraft table at the fab shop i used to work at. we kept a few scraps of plywood/cardboard under the table to cover up any open areas of the table when we were cutting parts. Those arcdroids look awesome and I'd love to get my hands on one!
Quick point - It'd be worth having something to suspend the cable for the plasma cutter - It looks like it'd wear through the cable after used for a long enough period of time.
I'm excited to see you get an Arcdroid, Robert! I was disappointed when a certain Fabrication YT channel got one and barely used it thereafter :/ With your background and love of CNC ...everything, I'm sure it'll really help your workflow and capabilities!
Brother, I appreciate you and your incredible personality. I seriously envy your garage space and the fun projects you get to take on. Please for the love of god put some eye protection on. I have the video paused not even two minutes in just to make this point.
OK Mr. Dunn, you are, as I've told people about me, a lot smarter than you look and you ever know how to use big words correctly. Amazing. Nice work of the plasma table too. Keep the good stuff coming.
I don't know a thing about downdraft tables except that they exhaust air, but I think you ought to put in a mesh screen over the funnel to sift out particles that might destroy the blower over time. Also, you could benefit from using quick-release pins for the support legs so they don't fall away at the right place but at the wrong time. Maybe use something similar to the type of pins that hold snowblower wheels on the axle.
Best way to not remove all your conditioned shop air as exhaust is set up a make up air. Same principle I have with my laser. Think of a restaurant kitchen exhaust hood, lots of air out but you feed it with controlled air in. Get you a cheap fan draw outside air in blowing at your table. Turn the exhaust and make up air fan on at the same time and you save lots of precious conditioned air. I was sick of my laser exhaust pulling out all my conditioned air in the Texas summer. Takes way to long to cool the space back down. This will create a mini hot or cold spot around the plasma or laser
Hi, when you talked about the issue regarding venting the plasma fumes and limiting the amount of air from your shop to the outside I thought "why he just don't take the air from the outside and then expell it" 😂 then I realized that such a thing would require not only a second pipe but also some sort of enclosure...
I just got that same husky table from Home Depot! XD. I was looking for a table that could hold my 3 monitor arm without collapsing under it's weight, and was getting frustrated because apparently table now means the cheapest tatt that you can rest a laptop on, vs this is evidently now called a work bench.
Another technique you could use to minimize the amount of conditioned air being sucked out: Bring outside (unconditioned air) air in to replace the air being sucked out: direct the outside air directly at the top of your plasma table. This will actually give you more airflow through your table as well: You'll have air coming down from above, plus air being pulled out from the table from below. So you'd be both pushing and pulling the fumes down through those slats. And since the air being directed down from your table is coming from outside, and since that same air is mostly what's being sucked back outside, very little conditioned air will get pulled out.
@@UnderDunnOfficial except more exposure to the plasma versus the vertical bars. Maybe this was already suggested, but having a few of the Harbor Freight fiberglass welding blankets on hand to cover the unused portion of the table would also improve airflow on the in-use area.
Next time you have a 48" long bend to make -> instead of cutting that piece completely off. just cut the majority of the way through the part, but leave a few spots where it's not cut (~1" long every 3-4" spaced apart) and then you can just simply fold along that line by hand.
Hi, nice to see you again on RUclips, i just saw that you removed all your video's,you had some great content there. i discovered your channel arround the time that you did your last video and i was bingewatching your entire channel back then. Grtz
In the future when you need to bend larger material don't cut all the way across, leave them 1 inch tabs throughout the bend area. Or you can make a relief cut with a grinder on the inside of the bend
I’ve used a water table, and it works well when you are actually cutting. But for small jobs it is a pain to set up and drain. In the makerspace I used we didn’t completely drain the table, but the process of filling and draining took quite a while. So it isn’t great for sporadic use.
Хобби
I should point out that the plasma cutting I did in this video is 80% of the plasmaing I've ever done, so I'm no expert! Also yes, I will be replacing the plastic hoses with metal ones
Yeah, watching all of those very hot sparks showering down into the flexi-poly hose was giving me visions of a future shop fire.
Maybe add a vortex slag droplet catcher? I hear there was a video out there where a woodworking one was made . . .
Although since metal is heavy it probably only needs a simple single stage.
But you are a clever bloke and learn fast :-D
Im not joking, you are a smart man.
Happy plasma-ing :-D
Well done! Keep an eye on the exhaust outside the shop. Don't let any sparky metal set fire to your yard.

Your plasma mascot there kinda looks like the spork in the last Toy Story. Fun Vid as always!
Nice plasma cutting table. Looking forward to more videos on the Tesla swap. 👍
Well now I want a plasma cutter. I have absolutely no need for one. Just want. For, uh, strategic plasma purposes.
Nice video man, :)
Another technique you could use to minimize the amount of conditioned air being sucked out: Bring outside (unconditioned air) air in to replace the air being sucked out: direct the outside air directly at the top of your plasma table. This will actually give you more airflow through your table as well: You'll have air coming down from above, plus air being pulled out from the table from below. So you'd be both pushing and pulling the fumes down through those slats. And since the air being directed down from your table is coming from outside, and since that same air is mostly what's being sucked back outside, very little conditioned air will get pulled out.
looks good an works good,
what else do we want or need, an it was cheaper then buying one,
an YOU made it !
That's the best kind of sponsored video: "do whatever you want with it"...
I wonder if the extraction would be better if the angle iron is set at 45°, that way the stream of molten slag doesn't hit a horizontal surface
Good question!
@@UnderDunnOfficial except more exposure to the plasma versus the vertical bars. Maybe this was already suggested, but having a few of the Harbor Freight fiberglass welding blankets on hand to cover the unused portion of the table would also improve airflow on the in-use area.
Nice!
If you add 4 " strips under the channels. So they work as individual dampers. So only damper is open, is where the cutting is
Next time you have a 48" long bend to make -> instead of cutting that piece completely off. just cut the majority of the way through the part, but leave a few spots where it's not cut (~1" long every 3-4" spaced apart) and then you can just simply fold along that line by hand.
Thank you for adding this to my mental rolodex of tricks.
Sweet plasma setup, Robert! Might I suggest a guard of some sort to protect your soft, fleshy bits from the vertical edges of those sharp, steel bits?
Hi, nice to see you again on RUclips, i just saw that you removed all your video's,you had some great content there. i discovered your channel arround the time that you did your last video and i was bingewatching your entire channel back then. Grtz
@@BjornV78 - Thank you kindly, I appreciate that! I'm glad that you enjoyed watching them.
0:42 dunno if the kids are still saying "mood" but this is a damn mood.
Thank you for the photosensitive warning! I have a migraine today, so I’ll watch this later :D
In the future when you need to bend larger material don't cut all the way across, leave them 1 inch tabs throughout the bend area. Or you can make a relief cut with a grinder on the inside of the bend
I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.
I’ve used a water table, and it works well when you are actually cutting. But for small jobs it is a pain to set up and drain. In the makerspace I used we didn’t completely drain the table, but the process of filling and draining took quite a while. So it isn’t great for sporadic use.
