Will Rob ever make an 1 rotor? I would love to see a 1totor miata with like 250 300hp. That would be sick
Check out Team Boosted. They have a 1 rotar but have struggled to get it running nicely. Sick little build though
I'm not sure a 1 rotor would be a good idea, i imagine the vibrations would probably be quite bad
1 rotors sound fuckin phenomenal
It would be so sick to see a 1 rotor from rob
Ive seen team boosteds 1rotor and its sick. But they dont do Rotarys for a living. Plus Rob n co can do anything
I would love a hotdog-plasma cutter follow up science video.
Thumbnail says, “No more hotdog!?”
@@redpanda1070 ngl I saw there was a bunch of non rotary content, and kinda just left.
Theres alot of salt in hot dogs sot itll conduct electricity fine maybe a steak or chicken
For experimentation and validation of course
Same
rob, i hope you see this. here is some tips for you.
that light when you pull the trigger is the pilot arc, allows for smoother starts, allows you to keep the trigger down as you move between places, and removes the need to touch the surface to start your cut.
if you want to cut stainless or anything high nickel chrome, you will need h5 gas to get a clean cut. or 95 percent nitrogen, 5 percent hydrogen. this also works for aluminum.
I would look into hypertherm because those machines can do gouging and have extended reach electrodes for reaching into tight spots.
All the Shops i worked in used Hypertherms, they go all the way to 115 A
@@meowtzy7gaming551 same, it's insane how it takes way less current to blow shit apart than to even stick weld isn't it?
Try “drawing” Crescent moons or C’s when mig welding. There are many styles for mig that some people like and some don’t like. Just try different styles out to find your personal preference.
that's what I do with flux core after a bit of wire wheel the illusion is perfect ^^
i prefer a consistant J for doing groove welds :)
I also use a figure 8 pattern with .030 Flux core and after cleaned up normally looks pretty good
All this welding talk… y’all welders got real skills! Wish I knew how to weld man I hate having to take my stuff to Someone, but because I don’t respect the work it’s just the diy’er in me
@@anthonyortiz4538 it just takes having the machine and practice. But the C and J technique workout very well
Little does rob know military grade means cheap 👌
Built by the lowest bidder, sold at the highest price possible.
Cheap, idiot proof, and easily fixed with common parts.
@@It-b-Blair as if
As someone who welds for a living its always interesting to see someone learn multiple processes for the first time. Mig welding can be easy but still takes time to master. Its much more convenient that tig but, tig is far stronger. Knowing which processes to use and how to apply them to your situation as well as the time it takes to execute them is my main focus as a welder. Keep on working on it, all love baby.
Also, the brand "Yes Welder" is actually not terrible for a home or garage welder. I actually have used them and for the price you pay it exceeded my expectations. Yes there are plenty of higher quality options that if you have the money for you should defiantly buy over the yes welder. This is for all the average Joe's like myself.
I'm glad you're giving the RX8 some love, it's really overhated and as a lover of rotary engines I feel you should try to make the best out of the bad situation Mazda made
It is what it is. I love my Rx8.
another great way to leave a "bead" with a mig gun is to do small little circles as you progress with the weld, this helps the puddle slowly move and gives you more control than just going with the forward-backward pattern
I’ve seen the C’s or half-moons for beads using MIG, but I always preferred making little circles as I moved across a piece. It gives you plenty of control over the shape as well as the puddle for getting proper penetration.
Yes! Came here to say this :) Slow down the feed a bit and make tiny overlapping circles
I have very little welding experience(most of which is mig and some oxy-acetylene torch) and doing the circles seems to be the most straightforward to understand and execute method.
I learned to weld on 30yr old Miller machines. My new job has a brand new auto set Miller. I struggle a little with it. The auto set seems to be set on BBQ!
We called them dime stacks when we were learning.
I understand that Miller makes good shit, but there's slim to no chance that most "beginner" welders who don't plan on doing it as a profession are going to drop $4000 on their first welder. I feel like this is for the professional who needs a more versatile tool to get various jobs done.
Feels like somewhere in the middle to me. I see it being useful for advanced hobbyists and auto shop or machinist who does that has to weld occasionally and need to use different processes (MIG/TIG). Most "Professional Welders" will have a couple different machines to do each task seperately. I do think Rob's shop provides a perfect use case for this kind of machine.
@@Hakudog5 I agree, just not what he said about it being a beginner machine.
My first real welder was a Millermatic 211. Not a do all machine but it does mig steel/aluminum which is all I wanted as a beginner hobbyist. I got mine with rebates so it was a little over $1000. That was a few years ago at least. I can't remember if that included the aluminum spool gun.
I remember my first gas MIG setup cost me around $600 but I managed that buying used stuff. Only thing new was the tanks because no local gas place would sell me argon with the used tanks I bought. $4000 is definitely way too high for a starting hobbyist. Even for my step up I bought a used 211 like the other guy said for use at the shop where we parted out and rebuilt Miatas.
That housing is gonna make big power, can't wait for the next RX-8 video!
When rebuilding an engine for the RX8, do a Renesis/SE hybrid. Use SE housings with Reni plates and rotating assembly and have a high rpm 13b with the best exhaust flow imaginable for a 2 rotor. 5 friggin exhaust ports. Mazdatrix did a setup like that back in the day but turbo in an RX8 race car. Super gnarly stuff.
He’s already talked about it multiple times just no videos yet
“of a running one”
Many have done using the REW housing hybrid with the Renesis as well
@@Amazarushi yea, but SE housings just bolt up as is is the only reason I say that. The REW housings have to be milled out coolant passage wise which I guess is whatever to Rob since he can and will machine anything and everything lol
When drawing high currents from extension cords if they are rolled up the cable on the inside will be roasted by the 50 feet of cable on top of it. Always extend your extension cord whith high power draw. Otherwise you will need to wait for it to cool down again, though I don't know what the duty cycle of that would be.
Its not so much that the cable being on top of itself creates the heat... coiled cable can create an induction system that basically works the same as an induction stove top. You can negate this by coiling your cable in a figure 8 pattern. No need to spread it across the floor.
^^^THIS^^^
Induction prevents current flow, creates heat.
I am a production MIG Welder. Here are some things to know:
Hold the trigger down and set the gas pressure to 30. Every time you change gas you will need to re-adjust this.
Listen to the welder when welding. You can hear when you are getting closer or farther away by the pitch getting higher or lower. You want to have an even pitch throughout the whole weld.
With thicker metal the settings mostly become personal preference. I encourage you to play around with the settings and see how the welds change. Thinner metal you have to worry about burning through your piece.
The "fake bead" technique you refer to is called a whip. It is one of many patterns you can do: whip, cursive e/circle, C/half moon, etc. The tighter you make the pattern the better. Important to note that these patterns don't penetrate as deep into the metal and won't be as strong. Some places don't allow patterns for that reason.
Change your gas at 500PSI. This is for the gas companies. When they refill the bottle they still want pressure in it so it doesn't get air contamination.
I know you need to acknowledge your sponsors
Just never thought I would see a 30 min infomercial on your channel
I love when I hear the perspective in which a person's passion interferes with everything he does "I see the welds on the workout equipment" such aspects really show the devotion! I love it!
Incase you didnt know, Rob, TIG stands for Tungsten Inert Gas while MIG stands for Metal Inert Gas.
You can also do MAG which is Metal Active Gas.
Argon mixed with co2 is an active gas, so that would be MAG welding. WIth pure argon its MIG
I've been watching for ever hopping one day you would build a Renesis. (be typical Rob and do what others can't figure out) You've smashed my dreams Rob! #supersadface
the best Renesis pro engine builder was Daryl Drummond and his engines generate ~270 bhp or 230-235 whp with unmodified factory side exhaust ports. That’s the bar to shoot for and the reality soon to be demonstrated here is that the peripheral exhaust port addition to a Renesis engine is one of the longest running hoax fails going, especially for a normally aspirated Renesis. Don’t take my word for it though, the results will say it all along with all the excuses that follow. The only silver lining is that they’ll post up real results rather than either just making BS butt-dyno claims or slinking away quietly and disappearing like pretty much most of the people who tried it and failed over the last 10+ years.
Just picked up my first rx8 for mountain runs/auto x/ track events and I'm blown away at how well the chassis handles.
Had mine for 2 months now and it is indeed a great handling vehilce
Mazda tried. People hate on the rx8, but Mazda really did the best they could. They made a fun chassis, but had to make it 4 door for tax reasons. They tried to update the rotary to match emissions standards, but it just couldn't. The rx8 was what they could do. The rest is up to us enthusiasts.
@@octane613 yeah bro, I just replaced the cat and catback pipes with a cat less and performance exhaust and it runs so much more healthy now. The stock exhaust esp being how old the car is was not letting the car breathe how it wanted to.
I've been tracking mine for like close to 20 years...it handles better than most of the students cars I've driven.
Just needed more power. Which it's getting now in the form of boost.
I thought I paid TH-cam for no Ads but I just watched a 34 minute Ad and I couldn't get enough. I want a Miller.....
Best Miller Info Mercian Ive ever seen. Thanx Rob, I probably needed that.
I personally have a "yes welder" and I find it welds pretty good for the price. I've used many other welders before. The yes welder is defiantly not the same as a high end miller but you do get a very good value and is perfect for a "home shop" or first welder.
Glad to see you're moving into my world of welding Rob. I'm a welding robot operator, as well as a day to day mig welder. It's fun and very fullfilling
Thank you daddy dahm ,I've been asking for a 7 port/hybrid video on the renisis sence the first rx8 vid
Kyle mohan kmr has videos on a hybrid
@@ericbrusuelas1807 I know but I wanted to see him do it
Oh haaahaa my fault 🤦♂️
I was hoping for a hybrid 13b. I guess he has no intention of using any of the 13b-MSP since he destroyed the housing and the iron.
@@danielkruger4305 nah he's trying to one up kmr
Rob: "excellent length, we've got phenomenal length."
Isiah: Thank you!
Lmao
Nice tutorial on welding. Thank you. I have a Miller TIG machine and love it. I like the plasma cutter, might have to go look at them.
Isaiah is hinting to cutting up the tube chassis on the 4 rotor huh? He seems to hate it lol
Why would he hate it?
@@iansmith5052 cause he didn't build it
My brother’s and I just bought a Miller Multimatic 220 two months ago for our shop. Been great so far. Still getting the hang of TIG. MIG right out of the box was great. Just a little fine tuning and even better
15:57 you don't need a quick release. Use a single way T splitter. There's more expensive ones too which work with the electric signal from the machine, basically you open the physical tap, you work, but if your machine doesn't excrete gas for a set amount of time (10, 20, something) the valve shuts down, so you don't get back the next day and learn new curses in Portuguese.
These tools are some of the first big purchases I made when building my work shop once I seen how valuable they where I had to have em best money I ever spent
good job guys! you all freaking ROCK!!
This video came out at the perfect time for me Lol I just bought a Renasis for my gokart which is currently Yamaha Vmax600 swapped and I am now doing what I’ve always wanted and throwing a rotary in it
Ayyyeee fellow welders where ya at!? I graduate welding school in less than a week super pumped to see this kind of content and all these comments, gets me excited!!
I was also told to angle the tip of the mig gun twords where ur going next it heats up the metal before you get to it making it not shocking the cold metal making it a stronger weld
I have one of those at work and it's fantastic
Love Miller Welder's! I have a Miller 215 Multi Machine! Love the welder so far!
Nooo way. Everything in this video is too cool lol a big ass port and a new exhaust port. Really wanna see the test run
Ahhh that feeling of a brand new tip and post on your plasma torch and then proceed to roost it straight away!!! Off to the store again ........
Thanks for the great video I love we learning with you
Dude I remember in the live asking you if you’re gonna rebuild the Renesis better and a potential timeline, so happy!!!
Your reaction to the mig process cracked me up. I think the biggest plus for it is that your fitment is less critical as you can use what you called “bead patterns” as a way to span the gaps to build up an area that doesn’t exist. As others have said a “c” shape that rolls back into itself is perfect for that.
Mig welding has a beautiful sound when it is adjusted correctly
Damn opening a box of tools is like birthday and Christmas presents at once 😍I feel that
I love that table top CNC arm for plasma cutting the the Grind Hard Plumbing Co guys have been using. I've been wanting to get a plasma table for a while, but the space.... I love watching that arm work. I need to plasma some things.
Yeah, but that type of CNC-P is kinda limited, even if space is a consideration, you're better off with a smaller table than that. There is an arm that could work with plasma, it's a water jet type, but that one's expensive as fuck, basically they slapped a water jet on an industrial mini arm.
@@aserta I have a couple industrial FANUC arms. I guess I should just put a plasma cutter on one of those... but it's a whole.... thing.
I agree on Miller products! Hell yeah!
When welding metal with mig I like to do c patterns to make sure it connects both pieces and you really need to play with speed and temp to find your style. One more thing is if you tilt the wand it gives you a great view of what you are working with in terms of is the weld hot or cold is your feed too high or low and you can see that after a second of welding
Your reaction suggests you've never used one before dude. Actual gamechanger, probably my favourite cutting tool.
Making up and down or even side to side weaving patterns with mig or crescent moons shapes as some comments are saying with your hand. Adjusting the speed just with your hands helps alot for finding your preference too.
Tig and stick for me feels a little similar in the hand/arm movement you can utilize.
Some of it even translates very well into mig welding too.
I've contemplated buying a multimatic in the past but couldn't justify it since I do no welding. I'll be looking forward to another review in the future to give your honest opinion of it once everyone's gotten used to the machine.
Can we just appreciate your a minute how far this man has come from harbor freight tools and has bottles just chilling in the open to now he's confident about tooling.
Edit: not on the lathe bed 😬😬😬
for me with mig welding I always would sweep up then down and forward. almost like drawing waves and overlapping the welds
Welding glasses are the shit. I have a couple pairs very handy for them jobs that you really wanna see while your welding or cutting
I've done some MIG welding with flux core wire using a ~€100 welder, fixing the floor of a van. Very thin sheet metal in the van, the sheets I was putting in was thicker, so I was burning through a lot. I was probably using too thin welding wire as I had to keep a very high feed rate. And the areas couldn't be properly cleaned, so water was constantly used to put out small flames, which in turn bubbled inbetween the weld and metal.
This is what pain is like.
nice to see all the mig welders talking about their Cs. The little snakes Rob did remind me of the kids that would write their name the first time they tried mig.
Rob dahm is the best
I'm still pretty amateur to welding but I do however have experience with most types of welding. I was taught that when doing a MIG bead you do circles the size of the bead desired when moving along the piece, and to make sure you push the bead not pull, so that the surface is protected by your gas
Congrats on your Izea 2.0 purchase Rob.
Miller sending out some fabricator drip to our boi Rob Dahm
Great info, will have to rewatch. Novice...
Love this haha!
Just don’t hold the mig torch like a plasma cutter, your supposed to “push” the puddle along at an angle with your torch down at a 45 angle
My lovely wife got me a 125 amp Lincoln 125 HD flux core love that lady best Christmas ever
If you turndown the feedspeed down you take it slow and you have less sparks. And I highly recommend to hold the torch with one hand and your thumb on the flex/ pipe to get more controll and keep your head closer at your work. Then you have more controll less sparks and you see what you are doing. Treat it like tig. What I mean with that is that you have to position your self almost the same. You can do nice work with it. Enjoy your new tools 🤘
Well it’s not the illusion of a bead it’s still a bead just made in a different way. There’s a great many different patterns that you can try and you just find which is the most effective and comfortable for you. Comfort is supervising important in welding as it can greatly improve consistency. I Love your enthusiasm about learning all this Rob keep up the making of amazing things and impressive work🤙🏻
Thank you based dahm
Rob's evil laugh after plasma cutting something 🤣
Rob what id sugest while doing mig is your left hand to be really close to the torch to help stabilize the tip, lose the right hand glove for better control and move left to right while keeping around a 45 degree angle of the torch to the surface not 90 you can see better that way. to me the overlaping that creates a "bead" helps me know im staying on track of what i am welding plus controls heat
Ugh those ballet moves make me wish I still had those ballet videos of Rob when he was 14. . .
I was half expecting a mini gatling gun in that case.😂😂
I was thinkin rail gun. Lmao!
I think you have to weld from left to right with the mig, so you can see what you're doing. Welded mig a long time ago and that's what they told us to do
I learned on and still use a harbor freight MIG welder. I believe I do pretty good welds but after seeing this video I'm going to go get a Miller
I actually really like stick welding, it was the first type of welding I learned, with an ancient old inverter and shit materials on a barn floor. It's fairly easy and forgiving, and it gets the job done quickly and cheaply. Of course cleanup is a bit of a pain. I also learned to MIG/MAG weld at school that year, as well as how to gas weld with oxy-acetylene. All that at like 13. Never learned to weld TIG though, might need to learn that now that I'm 18.
Stitch welding too can have a bead look and is good for thin metal
Hi rob, when is renesis 3 rotor coming?
Beast machines 💪
In PR🇵🇷 we have alot of Rx8 renesis engine with the housing cut off the same way you just the in the video. And we have alot renesis with 1st gen housing.. since 2018... but i love that the world is learning more about wankel engine🙏🔥
I love miller i have a dynasty 200DX and a snapon plasma and a cheap mig would love to get all miller
Few tips:
Watch out for gas flow rate
Put the torch cable on your shoulder so you don't have to stress your hands to relive the weight of it. Your hands are concentrated to do something that needs precision
I just got miller mutimatic on my jobsite we welding stainless tig things s beast. Running on 120
last time I was this early, the RX8 was still running
Pro tip: when setting gas flow on the tank for mig release the tensioner on the wire and pull the trigger to set flow rate so you don’t waste or have to rewind the wire.
That copper on the end is also where the current gets from the machine into the wire, which is why it's such a tight fit over the wire
I found the plasma cutter and digital welders from CEA brilliant they get u to put the metal type and thickness in and for welder the wire ur using and set the rest them self, and for plasma cutter u just have different nozzel size fot different thickness, same swirl ring and and electrode, was so easy to set up, but these were 3phase
Tig is great for stainless and aluminum, but mig is the best for mild steel and getting proper penitration like roll cages but stick can be used on a cage it's actually used more on structural steel and on site welding. 🚧
Tig will also look better without grinding but for speed you go mig on steel.
Also a suggestion, play around with zig zags and loop patterns and mig welds will look like you were rolling the cup on a tig
You had a very nice distance, and feed rate with that first weld, lucky guesses bro! Normally it takes striking a few arcs to get it dialed in, especially if you haven't welded before, or for a while
big things to watch out for with MIG, protect your glass, car windows get destroyed when you run a MIG too close. the sparks that fly off are tiny bits of metal that melt and damage glass on impact. protect machined surfaces like your mill, welding that close to your mill could damage the surface because of those tiny pieces of metal. not always going to cause a problem with that probably mostly with higher amperage stuff but I wouldn't risk it. and fire hazards cardboard, paper, fuels, can all catch fire. and last one is get used to welding while your being burned, don't lose focus. you start welding thicker stuff and eventually you will catch yourself on fire or a bit of hot metal will land in your shoe or glove or other places you won't enjoy and never MIG weld in the sitting position, you will regret it. now all of that said MIG can be very useful and fun.
Woooo got in at 8min 😂.
Hey man great car and watching your video have inspired me to work on my own cars
Biggest thing with mig (or welding in general) is be comfortable. Rest your hand, arm or lean against something. You’d be amazed how much that helps.
You get 2 types of plasma cutters, external grounded arc and contained arc. A contained arc has the positive and negative terminal running up to the torch, thus giving a contained arc, or a small lightsaber.
34:29 minute Miller ad.. but I watched the whole video and I was thoroughly entertained.
0:31 God that "tink" is such a satisfying sound lol
27:50 yup, I've welded stick before, really fun and satisfying. Although we called it Arc welding or SMAW (idk what it's short for lol).
Shielded metal arc welding is what SMAW stands :)
How did you know I wanted to watch a 30 minute Miller advertisement?!?! You’re a Dahm mind reader!
I know I'm late to the party but here are some pro tips for mig, you want to hold your torch at about a 10° to 15° ish angle, you can push or pull depending on what you're doing, I always say you should push when welding aluminum just because you get far better gas coverage and cleaner welds, and you're settings when set properly it should sound almost like sizzling bacon
The forward and pause technique that creates that bead look is not for visuals alone it creates a better quality weld this is for forehand welding at higher movement speeds typically on thinner metal. there is also backhand welding which is typical for thicker metal or larger gaps in which you create a C shape simar to TIG welding both of these create a somewhat bead look but aren't used for that but rather creating better welds. Also if you don't have Welpers i'd recommend grabbing cheap ones as the cutter is the right depth to cut the tip of the MIG wire to the desired length at starts of welds makes significantly easier starts and reduces cold starts or leaving a piece of the wire behind
You can do beads will mig by just running the head at a angle and depends on if you push or pull
Also for running beads, a lot of people go in little circles, or c shapes as the move in their welding direction.
"there no way its that small" that exactly what i said when i picked up a modern plasma cutter. i cant believe you have never used a mig. They are an excellent tool and can get alot of work done really fast with it.
That cart is bling, it even comes with Fuch wheels like from a Porsche.
5 Rotor Next. That would be Epic
Rob you will be laying sweet mig dimes in no time bro 🤙😉
