[@davesmith9325]

The key step is to get the hw working and Matt has proven that now. I'm sure arguino code with a massively faster response (even ballistics) an be done easily by any sw guys out there

[@BeefIngot]

I have a hard time imagining how the response wouldnt just be fast as heck unless he has like serial prints on every loop or something. Its literally a read input give output sort of thing where even the slowest ancient uno should be able to do that thousands of times per second.

[@jzab]

The throttle controllers I’ve used in OEM are feedback position controllers. Your foot requests an angle which creates “position error” in the system and a PID (or similar) feedback loop moves the throttle to correct this error. The output to move the throttle is not the same as the output to hold it still, and even holding it still in different positions can require different outputs. Then there’s signal validation from multiple inputs as you should have at least 2 pedal and 2 throttle position sensors, hopefully with one with an increasing signal and another with a decreasing signal. Some systems also have a plausibility checker, independent of the throttle controller, that oversees everything to make sure that everything is running properly. Once set up properly, modern electronic throttle systems can move faster than cable as they don’t solely rely on a slow moving person to operate.

Even better, disable throttle when the brake is depressed. All modern cars do this as far as I know, if the throttle input and brake input are high, it assumes it’s a runaway.

[@pbe6965]

@@bigiron4018 any software solution relies on the arduino, and in my experience they are not the most reliable piece of hardware in the world .... They're pretty good, but not bulletproof, I had one that froze and needed rebooting once while driving, it was only used as a speedometer and never had any other issue since then but I wouldn't trust it with my life. The salt might also make it worse. A kill switch would ensure he still has a way to kill the engine in case the electronic part of the throttle fails :)

You're right about 3D printing -- it can be a minefield of problems unless you have good control of the process and materials. Polycarbonate is good, but for high strength, high impact nylon is best IMHO. You can smash nylon with a hammer and it won't break, just like the car bouncing up and down on the pucks as you drive down the road. Send me your files and I'll print them for you, I've been through the minefiled already.

Upvote this man so Matt get's to read his offer

[@martylawson1638]

If impact resistance is the highest priority, then max hardness TPU is the go-to material. Taulman PCTPE and NinjaFlex Armadillo are the easiest to find. 1/2-1/4 as stiff as nylon but with >50% elastic deformation. It's amazing stuff and easy to print.

[@GaweNowakowski]

I dont know what type of printer Matt is using, but IMO I would stay away from high temperature materials PC/PEI without enclosed/heated chamber (in my tests the bonding strength of layers is compromised). Hard TPU or nylon would be my choice for high reliability, becouse it seems to be easy to get good results. i would use lighter colors instead of black to keep temperature of the parts lower, especially usefull in heavy sun exposure.

CRC Marine Grade Corrosion Inhibitor is your friend. It’s a cosmoline coating. Next time it’s stripped down, assemble the rolling chassis and give the entire thing a coat or two with everything torqued down. I live in the rust belt and coat all my vehicles with it. Works great, lasts several years, resistant to spray, and doesn’t drip like Woolwax/Fluid Film. Would be perfect for your use case.

Hi Matt, you can use low-viscosity cyanoacrylate (superglue) on 3D filament prints to make them MUCH stronger. You coat the whole thing in glue, let it flow into all the gaps between layers and then spray with activator. It's self-leveling but, if there are any bumps of glue, easily sandable. Particularly with polycarb filament you should expect an end result that is actually hard to damage, even intentionally.

For flushing your cooling system, citric acid should dissolve anything found in normal hose water and won't touch either metal or rubber/plastic parts. I bought some (food grade, no less) a few years ago, and it's gotten to the "when you have a hamm… citric acid, every cleaning problem is a citric acid problem" stage. (OK, citric acid or isopropyl alcohol.) If you get food grade you can also use it (sparingly) to spice up salads, cabbage, and/or cookies :D

[@AnWe79]

Citric acid and isopropyl alcohol gang! Anytime you see vinegar recommended for cleaning, swap it for citric acid and your nose will thank you. Great on rust too. Citric acid I get in ~kilo containers from the "orient" food stores, way cheaper than the bulk plumber bags I could find around here. Isopropyl ain't cheap around here (I get it from a retail electroncis chain at almost $30 per L, probably cheaper in bulk if you've got connections) But it really is the shit, dissolves most gunk, safe on most plastics, and leaves no trace behind. Acetone or brake cleaner for the really tough crud, but plastics beware.

[@herrbrahms]

Good tip! Iron citrates drop right back into solution. Calcium citrate is more sparingly soluble, so a little splash of hydrochloric acid to lower the pH to 6 or so will make extremely soluble calcium chloride. Then you can flush out the crud while etching maybe 0.001mm of aluminum from the interior of the engine. Discretion is the better part of valor with that stuff.

Salt water, on the other hand, will dissolve anything metal and won't touch the mineral deposits.

Of course getting the silicone off to work on the system can be a challenge but you can't have everything.

[@bobroberts2371]

For bolts that are tight, ( but not heavily rusted into place ) which use internal Torx , reduced size allen / phillips , hit the head of the bolt using a flat nose punch. This will compress the metal under the head reducing tension. This also works with drain plugs that use a copper crush washer. Sometimes plating will cold weld bolts to the part, hitting the head from the side can help as well.

I've been dealing a lot with DBW on a MS3 for the last months, project started as a stand alone PID controller that sampled the PWM of the idle output, pedal position sensor and reported to the ms3 thru an adc a fake TPS, worked good but had a few issues with hiding the idle movement from the TPS as in the end I just reported the pedal position and let the MAP do its job at idle anyway. I just finished yesterday the V2 that runs thru CANBUS, for the love of god USE THE CANBUS, the MS3 integration is great and it will idle and change state looking at the pedal not the TPS position (I was afraid it wouldnt go in idle as the TPS now becomes the butterflys position and if you are using the DBW idle aswell it the TPS will idle like at 2-5%). Easy peasy, address 256 is the MS3 "input" 4 byte long, first 2 bytes is throttle position, last 2 bytes is pedal position (might be reversed, going by memory) then address 260 is 4 bytes aswell iirc but only the first 2 bytes are the target throttle position (the one the PID loop control needs to place the butterflys at). All is running on a ESP32 and i've added a few commands thru serial bluetooth to set PID, Deadband and Pedal/Throttle limits. All of those parameters need to be set in the controller, I hoped I could set them in the MS3 software like the canbus number goes from 0 to 4095 but clip it at 500-3200 but nope, no big deal tho. Also an other thing to keep in mind is to use BOTH potentiometers in the TPS and Pedal, I used just one of both and I fully understand the safety concerns, i've added protection against potentiometers issues like full scale readings (means that one of the wires probably detached or the wiper broke) but doenst protect against random readings that could make the throttle move in all sort of directions. My personal opinion is that if any of this happens dump the clutch and turn the key, I'm running a 1.3L Suzuki samurai engine with YZF R6 Thottle bodies, lots of noise not power (I wont be accelerating at mach Jesus even in WOT). If you want to take a look at the code or have any kind of questions feel free to text? me :)

Up here in Southern Ontario (and most places where salt is applied to the roads in the winter time) we take our car to a shop and get the frame/body/crevices treat with a corrosion inhibiting product. My personal favourite is fluid film, you can use a fluid spraying gun with a reservoir, hook it up to your air hose and go to town. It works quite well and you can apply to pretty much any surface because it's lanolin. You can definitely watch a few videos on this subject. A good idea also is to completely seal off all structures which are hollow. Any kind of hole will allow water to enter unless plugged with a rubber/plastic end cap. That eastwood stuff you used it good stuff too. I haven't personally used to on my own cars but I've seen it done with good success. Compared to fluid film, I have no idea how robust it is, but fluid film seems to resist some of the most severe winters we have up here.

As a northern auto mechanic, this video is more my speed. Unfortunately, this level of deep corrosion is very typical for any vehicle that's 8-10 years or older in my area. I highly recommend zinc flake coated fasteners if you are able to source them in a viable way. Speaking from experience, Geomet type coated fasteners are much, much more resistant to salt corrosion than bright or yellow zinc. The only thing better is a 300 series stainless (obviously except for more exotic materials), but as I'm sure you area aware there are other drawbacks to stainless fasteners to consider.

[@stuntvist]

Either that or stainless fasteners (which get used on bridges and such and have to be regularly replaced anyway due to saltwater corrosion). Ideally you'd use something that doesn't corrode when it comes into contact with salt but I don't think you want the worlds weakest fasteners on a sketchy land speed car or something that has next to no tensile strength and will crumble if a suspension arm bends an attometer too much. Oh, and for the record a lot of languages call stainless steel rust-free steel if you direct-translate the term. I don't know how that happened since you'd know just how not rust-free stainless is in the longer-but-not-really-long term.

[@natebeatty7325]

When I was a mechanic on the east coast where every winter day is a salt spray test, we would spray used motor oil everywhere under the trucks with a cheap sand blaster gun. It was the only thing that worked, and would be 100% rust proof if done once a year. Any existing rust or dirt helped the oil stick even better, so you didn't have to do any prep other than hosing off first. The various coatings didn't work at all, and sometimes made frames more rust prone, since it would trap water that found it's way in. On something nicer than an old plow truck, wd-40 might be a good alternative. Of course, you'd want to make sure that trapped oil wouldn't make its way out onto the tires at high speed. At the very least, I'd coat the RV in it.

It's worse than that. The stainless particles are electrically isolated by the paint or else they would accelerate corrosion. Stainless is more noble than carbon steel. If you put stainless in electrical contact with carbon steel, the carbon steel becomes the sacrificial anode. That Steel-It product is a gimmick. The paint coating system itself is doing the heavy lifting here.

This is why I spray my bikes down with wd40 after an off road trip. I’m sure it’s not as bad as salt flats but I do end up with muddy sand in everything. When I get back I’m beat and will put off messing with cleaning for days sometimes. But I blast it down in wd40 everywhere. I buy it by the gallon and use a spray bottle. Not only will it stop rust but it also loosens all the dirt and grim. So when I do power wash it everything just falls off with zero effort. Then for good measure I mist a bit more wd40 when I’m done. I know it sounds reckless and dumb but the results are amazing.

[@JxH]

@Matt 13:00 Speaking from experience, I believe that the engine performance can be improved by tidying-up the aerodynamics at the throttle plate. For example, those two screw heads that hold the plate to the shaft. Make sure they're tight (Locktite'd), grind the heads flush to the shaft, carefully stake the remains in place with a center punch (centerpunch the threaded join so that it can never rotate again, with the shaft well supported obviously), and then polish everything smooth. Obviously the airflow at the throttle plate is relatively extreme, so tidying up the airflow at that point seems to make an obvious improvement to the engine's performance. You might want to have a spare throttle assembly on hand in case something goes wrong.

The best way to clean salt off is the same you you got it on. Drive through wet streets preferably with some standing water. I do this the first rainstorm every spring. All the salt in all of the pockets it gets trapped in are gone. Pressure washing doesn't do this but simply driving in rain does.

[@ummduhgmail]

That seems a little more than impractical in this case. Also, he's in so-cal iirc.

[@dren4k]

Nah, won't work, my car lost chunks of it in summer, when most of the salt are in winter Just use the pressure washer

[@BenCarpenterWrites]

Yeah, a coat of fluid film before heading to the flats and after every rinse. It’s how we keep Toyotas on the road in the Midwest 😂

[@ummduhgmail]

It's really thick though. (And messy, I use it myself in WI)I wonder if a wd40 bath from a fogger can would be enough for a run or two.

[@tuffaluffagus]

@@ummduhgmail It might be a little risky coating a race car with a flammable product.

[@accordv6er]

Fluid film does wonders as a prep Matt! I'm running dbw on a speeduino ECU for my Mazda, so far, long as the sweep is calibrated and it has power, no reliability or weird issues.

[@dustin9258]

We have the exact same opinion about 3D printers. Built a couple 10 years ago and it was just constant tinkering to get mildly useful parts. I just bought another one as well and so far it doesn’t look that much more reliable than they were 10 years ago.

[@techman8817]

For work we pay others to 3D print with MJF. That’s a $200k machine though. Our formlabs prints are crappy in comparison, and those are a $5k machine.

[@bobroberts2371]

Time 225 king pins locking up. This will cause instability because anytime you need to make a slight steering correction, you must apply more force to overcome starting friction, this results in an overshoot and the need to input a steering correction in the opposite direction and the same overshoot.

[@kenlamb502]

A friend went to the salt flats with a newly built street rod a few years ago. I bought aerosol fluid film and applied it to the complete underside and into any and all crevices. He told me everyone asked him what was on the vehicle and stated that next trip they were going to do the same. This was 7 years ago and has never had any rust issues with it.

[@sexyfacenation]

What is aerosol fluid film mate?

[@kenlamb502]

@@sexyfacenation fluid film is an American lanolin based rustproofing. Invented at least reinvented during WWII. It was used along the US coast to keep all the big guns from rusting from the salt air along the coasts. It's a rusrproofing that up in Maine where we use salt or liquid calcium chloride to melt snow and ice on our roads. This product is a sprayed onto the exposed sheet metal under the vehicles to keep them from rusting. It can be purchased in a rattle can to apply on the exposed surfaces as well.

[@Foche_T._Schitt]

10% phosphoric acid will convert Iron Oxides into Iron Phosphate. Then spray the insides of the frame with lanolin.

[@matthewschultz899]

@ your king pins: we, here in Wisconsin, call it that special "brown grease". Another anti- rust option I've used a lot on plow trucks is an aerosol wax-based open gear and chain lube called velo-plex. Nasty stuff until hardened and lasts through several rounds of pressure washing.

[@jackrichards1863]

I notice there are such a bundle of contrivances for numerous purposes aside from being as light as possible to assist a higher top speed at a lower energy output. Bearings are heavy and brass or bronze (better) bushes are both lighter, durable and carry a heavy load longer. One thing that does good to be heavy is coats of paint. Another idea is the wax we spray on our car in these advanced times to make them shine. Spray on rinse off. Probably doesn't add much weight either? I attempt in a small way to think of things that might help as the salt is a hobby for wealthy & one car per season does not seem to be within your budget? Those cables for the throttle are fairly hefty . Fixed. Good video Matt, thanks!!

[@allareasindex7984]

Weight is not an obstacle on land speed vehicles as long as there is sufficient room to accelerate. Many wheel-driven streamliners accelerate fairly slowly.

[@CalMariner]

11:57 - Could not recommend MarkForged printers, click print and pick up your part in an hour or two. Super consistent dimensions, good stiffness for things like your air filter adapter. We use ours in a maritime application for on-demand fixes of science equipment. Not a hobby, it's a tool.

[@michaelodonnell8306]

I've had grand success in marine environment, preventing corrosion between stainless and aluminum with tef gel (do not eat). Also waterproof grease on bronze thrust bushings to keep out salt water. When we ice raced in Maine (brackish) we used a fresh coat of wd40 to keep the ignition working. Great vids. Thanks.

[@jimysk8er]

what about having flush-out bungs at opposing ends of frame members so you can run water through to get some of the salt out and then air to get the moisture out? bonus points if you then flush it with undercoating or something else to prevent rust on the insides.

[@kazzxtrismus]

pre-wsh the car with bodyshop "spray mask" its basically a soap...the salt will sit on top...but when you wash... the soap is already there underneath and in the nooks and crannies before the salt can get in.....just cake it on

[@Captaindan7141]

The Steel-It paint on the frame likes a low grit sand first. I sanded my rollcage with 80 grit and did a couple of coats. I pretty much stand or walk on my cage every time I get in or out and you can't tell.

Great Video as always and good choice on the 3d Printer, especially with the requirements you described

Which printer is that? I have similarly avoided getting one because I just want parts, not a printing hobby.

[@janivo5218]

@@davidbell-yt It's the Bambulab X1C if I'm not mistaken. Any of their other printers are also really good and can make most 3d Printing jobs a breeze. Bambu is on top of their game when it comes to making printers reliable and easy to use. They are like Apple of the printer world, quite limited in upgrades and customizability but has 99,9% of features a user could want. The difference to apple is the fact that they sell you replacement parts for cheap and encourage home repairs that will eventually happen as with any printer (a lot better though than most of the competitors)

[@tristanbuckoke9121]

Spray polyethylene is a great way to seal up for salt corrosion. We top coat with paint . Here in Australia many mine sites run on bore water which is far saltier at time than sea water . Could be a good way to protect the frame and trailer. Cheers mate

[@janofb]

Just a suggestion. Try KBS Rustseal. I use it on frames of cars I restore. Nothing gets through it. You have to grind it off to do any welding after the fact. Way cheaper than your spray paint.

[@jessetait5839]

The best rust preventative I’ve ever used is ACF-50. I have a fogging system to git into airplane structures. It’s fantastic.

[@fericyde]

if you can ditch that big-ass connector with the small pins just do that and replace it with some generic weather-packs -- guessing about 2-3 decent sized ones.

[@droid1171]

Hey Matt when using abrasive (eg carbon/nylon/ etc) make sure that the entire work path of the filament (not just the nozzle) is rated for that level of abrasion. CF and nylon are generally considered to be a harder material to work with comparted to the normal PLA but worth the extra hassle if you need that level of resistance. Zach Freidman has a good series on trying basically every type of filament and you might like to check that on out

[@operator8014]

You need an oil leak! My truck covered in oil survived a couple trips to the salt flats about 20 years ago with virtually no rust anywhere.

[@bytesandbikes]

I like to soak the exposed areas in cheap, knock-off WaxOil, then clean it off after the outing with strong detergent and the pressure washer. The wax coat is sacrifical and gives you a while before grit eats into paint. 🤠

[@gavinhassett479]

The insides of all those tubes will corrode... moisture/salt water will get into all the bolt holes. Good idea to also mist the insides of tubes with ACF50, or LPS. They will last longer.

[@dfgaJK]

That looks like a very slow throttle actuator response!

[@dubsydubs5234]

Spray coat everything (not hot stuff) in clear wax it works really well, it doesn't last very long (it lasts a few years) but you just add another layer and touch up scratches.

[@sdmoparmaninsd6713]

There's a similar product (probably by the same manufacturer) called Zinc-it, it's a gray primer color and dries almost instantly but I've used it on some bolts here in the Detroit area on winter driven cars with good results, you may want to give it a try maybe as a base coat before black...

[@d00dEEE]

Re grease. I've been using boat trailer bearing grease for stuff that goes near water/salt. The stuff I have is this deep blue, fibrous sticky ass stuff that will not come off your hands with normal soap and water, so my belief is that it would be great for Bonneville wheel bearings (and maybe on bolt threads, too).

[@getahanddown]

I made a spacer for my engine mount that sits by the exhaust + radiator. Holding up just fine. You're using it captive in compression, should be sweet

[@aserta]

3:10 without heating them too much (cause you don't want to harden them) heat your hardware with a torch and drop them in HOT used motor oil. Done outside, for... obvious reasons, this will protect your hardware against rust as best as it can be protected. I'd do a few tests on the minimum heat you can do them without damaging them. I usually heat them up for 50 seconds with a map torch hung by a wire - specifically until i see the wire get red hot (it's hardware store wire used to tie rebar for concrete - cheapest of the cheap metals) then dunk it. The heated oil is done in a stainless steel pot filled only with enough oil to cover the hardware i have. Some of the hardware i "blackened" in this fashion has been outside, in the elements for a few decades now. But the biggest proof of concept as far as i'm concerned is my brother's farm equipment where, whenever i take stuff apart, i do this to all the bolts that aren't hypercritical to be untouched (engine, transmission). I plan to test the this further down the line to enable the use on those parts as well, but for now i limit it to body and fixings. No issues so far, haven't observed any snapped bolts, at least not where i haven't seen them snap in the past in similar conditions. edit: sidenote on paint and rust and the frame. It will add weight, but you can drill holes in the frame, put paint inside and then turn that frame about in all directions for the paint to settle and form a coat on. This will create a barrier that lasts pretty well against internal rust. Have not tried this on anything big, but i do have a small trailer that i have done this on and i haven't seen rust weep out of it anymore whereas before, i'd get rust weep every time i'd drive it in rain.

[@imsurroundedbyidiocracy]

With a quality printer like that x1 carbon I've found that most errors when printing with engineering filaments is due to water in the filament. I fixed almost all my issues when I started printing out of a dehydrator.

[@kwaka140]

I made my trailer using 50X50 equal angle. There are no cavities so nowhere for moisture and salt to hide. The completed frame was hot dip galvanized. 23 years later there has only ever been one spot of rust. Literally a spot, like a point. Not bad considering it lives outside.

[@paulheitkemper1559]

yellow isn't zinc, it's cadmium. As far as painting the inside of the tubing, that's a good idea, but you might want to look into shooting the tubes with fluid film. It's a thing that they use in the Rust Belt to coat the underside and interior metal spaces of their cars to keep the salt demon at bay.
