Hats off to Mitutoyo for the sponsor. Nice seeing big company supporting the channel. Those spare pistons maybe classified as shotgun slugs - beware

Hairspray high hold stuff is what alot of people use to combat 3d prints lifting from the bed.

They will think the plastic bag of oil is a gun and possibly catch on fire, but they will ignore the fact that it's wrapped in highly flammable styrofoam. Got to love the TSA.

I hope you have a fantastic and productive time in Colorado.

I know someone who did moped racing in the NL from the US and brought everything via plane. They cleaned as well. What got held back by TSA was the shocks (and everything else in the bag) as they contained compressed gas. Watch out for that if your damper does.

I worked in landscaping and just after 9-11 I carried my wife's bag to the airport. Every alarm went off just from the cross commination from my hands to her bags carrying handle. What a mess!

Doesn't feel like 5 years. That covid dragged on a bit!

I have moved car parts like that, I also left a note. They called me over the pager at the airport and I went to the security. They asked me to open the suitcase and as soon as they realised it wasn't a gun or a bomb they let me close it up and go on my way and they sent it through no worries.

I traveled across the US with a rifle case full of firearms (big range day with my Pops). I laid everything out, told them all firing parts were separated, and put a note with each firearm giving make, model, and serial number. When I picked it up from claims, they thanked me for making it so easy to check everything. Has anyone ever been THANKED from any airport personnel?

Baggage has some form of strap you can sling over a shoulder and can carry without holding. Luggage is bigger heavier and has a handle to help ‘lug’ it around. But in practical use the words are interchanged with a broader meaning of ‘your stuff’.

If it fails again, try printing it with your 0.8mm nozzle before going to aluminium. You’d be surprised how much stronger 0.8 prints are compared to 0.4

An Aussie expression “I’d give my right arm to be coming with you”. Have a great trip mate.

What I think of when doing the comparison of baggage and luggage is that baggage is probably small things that you can fit in a bag. Luggage, I think of lugging something around. So probably larger or heavier things. Just a guess using context clues

You know the series "Moonshiners"? Tickle went to rally up support for home destilling. Therefore he had an appointment where he had to pass security. Being asked why he had so much cash money he repiled "I was coming to see a politician and thought that might come in handy." Guard laughed, sent him on his way. Just be You- this isn´t Your first rodeo, is it? Treat security like four year olds with guns- that should work. "Yessir/Nosir" That they like.

If the reed cage experiment doesn't work out , I had a forward thinking idea , might you have access to air compressor disc Reed valves , it is a disc with a conical spring in a threaded insert , they are very robust,,with your ingenuity im sure you can accomplish great results🎉 ,love your vids

U can connect the cover fan to the same output as the hotend fan which is always on

Baggage is someone that wants you to pay for everything, luggage is something you use to leave the baggage behind.

You've been my 50cc inspiration for years and am hoping to shake your hand at SpeedWeek 2024.

Make sure you seal that CFN print. It's still hygroscopic after annealing (printing) and WILL soften over time as the moisture in the air plasticizes the material. It will also change shape and expand. You must post process that print.

I moved my display, power supply and electronics outside of the enclosure I made for my Ender 3. I never had an issue with the board, but the display would get all sorts of wonky when printing ASA in the enclosure.

Good thing to add to your Mychron 5, is a LCU one. Will also log Lambda, but you will need a 12v power supply. Also look at the Smartycam option. It’s expensive but logs video and data.

Best of luck, safe travels, especially on the salt!

Good luck bro, and have a tonne of fun !!!

TSA- everything is a gun.

Hi Alex! MC Proparts in Germany makes a nice aluminum cage made for the big DEPS Malossi case for the ciao… it’s called the MCMV21+ . They are badass!!

Good luck at the speedway track 🎉🎉😊

im very excited to see the final results of this built, it is amazing to follow your progress.

To get a good seal on the reeds, you need lap it on a hard surface.

the new reeds look so good :D

I've noticed the textured glass beds from Creality are not even. I switched to a magnetic PEI bed and never looked back. Significantly more even, and easier to work in general. This is from 6 years of owning ender 3 printers and working on 15 of them regularly.

You can just wire the fan straight to the 12v on the PSU plug if needed! There are also replacement boards you can get with an extra fan header!

For nylon prints you have to use PA glue stick and cover all your printer with a trashbag. If you create a hot atmosphere you prevent warpage.

Jag hoppas du har kollat upp vilka importregler som gäller. Du borde prata med ambassaden och fylla i en carnet så du slipper betala tull eller att de beslagtar grejerna!!!

You’ll be fine when it comes to TSA, I used to fly with my nitro RC buggy all the time And I didn’t clean it super thoroughly

I used to have a Tillotson carb on my ‘68 FLH, no floats but a membrane it used to be virtually immune to vibrations 😂 it is able to deliver more than enough fuel with nitromethane in mind, now that you go to its homeland, a good acceleration pump and a booster to atomize the mixture like the Weber DCOE. Just an idea.

Tony Doukas is the guy u must contact for Reed blocks and valves.

Outboard motor reed blocks are tough and metal.

Ah the TSA. The initials stand for Talking and Standing Around. I spent 11 years in Federal Prison. The reason that is relevant is that when the TSA was formed, they recruited heavily from Federal Corrections Officers. These creatures are the least intelligent and laziest in the employ of the Federal Government. The Department of Homeland Security conducts regularly scheduled and "surprise" tests of the TSA's ability to detect suspicious packages and items passing through their checkpoints. It may interest people to know that the TSA has never failed to miss each and every item, no matter how obvious. Items missed include hand grenades, firearms of numerous description, ammunition, binary explosives, the list goes on endlessly. What they excel at (besides stealing a paycheck every two weeks) is confiscating any and everything that strikes their fancy. There are 'special' trash cans in which passengers -may- be allowed to throw away items the TSA deems a threat to aircraft safety. At the end of each shift, TSA employees collect these receptacles, take them out of sight of the public and take virtually all of it home with them. I have overheard countless Corrections Officers bragging about the loot their spouses (former corrections officers) bring in every day as TSA employees. The take away from this rant is as follows: were you to transport actual bombs, you would almost certainly get away with it, however, that family heirloom pocketknife that your Grandfather left you will be immediately seized and used as justification for sending you and all your luggage through a complete, invasive hand search (which includes swabbing with a 'drug detection swab', notorious for inaccuracy). If it sounds like I have a grudge against these creatures, it is because I most certainly do. Take my statements with a grain of salt as you would those of anyone as obviously biased as I am. Ask yourself, however, how such a bias was instilled before disregarding. Thank you for your content, I thoroughly enjoy each and every posting.

Man, I live in Colorado too. I sure would like to meet you once your here. If you let me know, I'll definitely make that drive. I know he's in Rifle or somewhere around there

Thank you!

When is the date in Bonneville ?

Wire the control board fan to the hotend fan output so it runs all the time the printer is on.

floater does not have to be gravity aligned. it can be a directional valve. like in a water line.

I was wondering to get me one of those filament dryers. Are you happy with yours? Also i have advice with cf nylon. Use a 0.6nozzle. It has WAY less chance of clogging than the 0.4. Personal experience that cost me a customer relationship.. I always thought that baggage was like a suitcase and luggage was cargo that needed a trolley. Like skies and bicycles. Kudos on the result from an ender3 sir. Mighty impressive slicejob.

Hello, I miss the garage and the new results of the engine. I hope you haven't given up. Unfortunately there are already 50ccm 2-stroke engines with over 20 HP. What do they say? No master has ever fallen from the sky. Everything takes time. I come from Germany (Düsseldorf) Greetings Hallmann

Determining the absolute theoretical maximum horsepower of a 50cc engine is quite complex and depends on several factors that can be optimized in theory but are difficult to achieve in practice. These factors include: * Maximum RPM: Higher RPM allows for more power strokes per minute, but achieving very high RPMs is challenging due to friction and material limitations. * Volumetric Efficiency: This refers to how efficiently the engine fills its cylinders with air and fuel. A perfect engine would have 100% volumetric efficiency, but real-world engines have losses due to valve timing and intake/exhaust resistance. * Thermodynamic Efficiency: This is the efficiency with which the engine converts the thermal energy from burning fuel into mechanical work. Theoretical maximums can be approached with ideal combustion cycles, but real engines have heat losses and inefficiencies. Considering these factors, theoretical maximum horsepower for a 50cc engine could reach around 20-30 horsepower, but this is highly theoretical and impractical. Real-world limitations would bring this value down significantly.

If the engine has to move fasten it to the frame with hairy string.

Have a safe flight.

Looking forward to follow your efforts in usa

Mind if you’re not doing so already carbon fiber orientation on your reed valves. Once I had a hard time with those breaking on my MRC go kart engine cause of the carbon sheets orientation, till I realized sun light bounced on them differently when they were incorrectly oriented. I’m talking about polini 0.25mm reeds

just a heads up. and i hope you read this. tell TSA what your coming to america for and they will let it slide most likely

Humm I wonder if metal reeds and metal cage would create noise?

You think TSA agents can read/understand?

What is the goal for HP and rpm of the 50cc engine?

You have mill. Why don’t you skim the surface of reed valves to level the planes with an end mill?

The large carb with no float bowl…as a interim proven unit….old but gold….no float bowl , therefore as efficient….it’s called a Wal Phillips fuel injector ..look it up on the web…..made by a multiple record holder…..and adjustable !!! Should you wish to try one I have one to lend you, just let me know 👍🚀totally mechanical

Do you know how much the airline charges for extra baggage,you definitely need to ship all that stuffing if they have a problem with it they will just open it and take a look and send it on it's way,don't breathe fibers , good luck

Should have gone for the Alfano 6 👍👍

NOTHING can survive Nitromethane.

I am building a rotary valve moped engine but I cant seem to find a good source on how to time the open and closing of the disc in relation to the cylinder ports! anyone have a video or website?

I have an Ender 3 V3 ke in comparison to my ender 3 pro in print time and preparation its extremely faster the klipper alone is worth the under $300 usd

I will buy more mitutoyo stuff now...

Good luck

Instead of taking your parts through TSA mail them to your location ahead of time!

Why dont you just ship the spare parts? Besides the potential TSA hassle its probably cheaper than the extra luggage price....unless you plan to bring it all in one piece of luggage and carry on bag.

Brute Force Concept BFC-engine

Fuel injection

My takeaway from this video?.... They'll think it's a gun. Lol.

You aren't allowed to say gun on RU-vid, you need to call it a pew-pew 😂

hello bidalot go all so boneville year for race 100cc

boyesen rad valve

👍🏻

USE YOUR MOMS HAIR SPRAY

TSA... Its oily, thinks its a gun. Carb, its a gun. Steering damper, its a gun. Pistons, its ammo for the gun. Speeking half decent inglish, he probably got a gun...

Are you still with NordVPN?

😎👍🇺🇲

Why are you not going with metal reeds??? Metal reeds break from old age being used for a long time. That is not the case with your engine. You will be checking your reeds every 30 mins of operation. If metal reeds fail then reeds will never work. Metal cage and metal pedals and be done with it. If metal cage and metal pedals fail in 30 mins or less then reeds altogether are off the table and must re engineer the system altogether. So why go thru breaking cages and breaking pedals ea breakage cost so much time end effort and redirection. Just go metal on metal and it either wrks or it will nvr work. In the end you will save so much time. If metal on metal fails then yes you have to fix the carnage witch is straight forward parts like piston bearings sleeves. All stuff that you do in your sleep. But instead your going to try plastic on plastic and have a failure then go through fixing the engine and upgrading to plastic on metal and have a failure and have to fix all broken parts and upgrade to metal on metal and then if it wrk great if it fails then it fails. No matter what you think in your head right now. You are going to end up with metal on metal period. Period. There is no chance your going to stop before you end up with metal cage and metal pedals. So skip the hundreds of lost hours fixing what breaks and skip the hundreds of hours of down time from the cage and pedals and just go metal on metal and be done with it and put all that saved time and effort into something else.

Your not suppose to say the G word here in the United states aka America

First

Congrats on gettng Mitutoyo behind you. That's awesome

If you have time get some VCI paper and chuck a couple of post it note size bits in those crank boxes. The luggage hold is generally pressurised but it is usually much colder than the cabin and that causes condensation on everything when you land 👍

This man is so grateful it makes me feel warm inside

Breathing carbon fiber dust is very much NOT A GOOD IDEA. Big fail brother. That stuff is very bad for your lungs. Don't dealive yourself!

I'm pretty sure the main difference between baggage and luggage is the spelling 😂

On my ender 3 I soldered the control box fan to the 24 v power. It now runs all the time and never overheats

Travel safely - we need you. Hopefully the TSA agent is a subscriber to your channel - that would probably help the process go smoothly.

I think your humorous bantering about bombs and guns in the context of boarding a plane to the US could not be totally understood by the IA search engines of NSA and FBI...Fly safe

Long live 2 strokes

Why not just send all this ''suspicious'' stuff by post while you take the plane with less luggage? Been sending sketchy rc nitro stuff to states from europe with no issues for a while already

Definitely think you are on the right track with the reeds , they flow worse , but they are also under pressure, looking forward to seeing your adventures at Bonneville

Please try an opposed piston setup. I think it would simply things for you and be a much more efficient design, particularly for high boost application.

haha i like how thoughtful you are with packing, i once took a complete moped through europe in two regular suitcases

Have a great trip!!!!

Try Gyroflow to stabilize the GP5 footage 😊Also, I use steelwool to clean my beds. The type with the soap that you use to clean kettles with. Works great.

thinking about your sponsor. There should be services that you could use to completly flood spam-callers and scam emails with. The idiots make one spam-call/scam email and you could send 1 million spambots to them instead. I think its season right now for these idiot criminals actually...

oh 😲 , not nord-vpn anymore ? in 🇩🇪 we named this Schutzgelderpressung if other protect you but must pay for... - no way ! that norway military can not protect the telephonetic line's

A $100 bill is a very bad idea. It's just a reason for TSA to lose your whole bag. It's easier for them to explain a lost bag than a bag that has been opened and is missing valuable items.

Alex. Befor you cut the reeeds take into account that there is a reed direction. You cannot cut snyway you want. This is because of te way the nylon is woven. Polini gives the direction to cut but mmaalossi does not give you it. But you can feel the tension and know the stuffer wat is towards the engine.

It's going to work just fine... You don't need high flow reeds... The blower creates the flow. You need a strong cage that doesn't fail and looks like you built it 🙈
