@pete2778 Hey sorry I mis-read you it happens. I didn't realise you have a fondness for hot oil in your face. If you like rotaries check out Kermit Weeks channel if you don't know already.
Nicely done. Its definitely a piece of engineering marvel. As a machinist, I am curious to know how oiling system works and how the top end stays lubricated without rocker covers.
It's amazing to see a person with that much talent operating a milling machine, but the ability to engineer the final engine is truly awesome. Beautiful work!
@@panzerlieb yep..you can easily see that....i can easily see kim kardashen naked...dosnt mean im gona fuck her. you would have to be nuts to do that. well nuts to fly in it.. all the 1000 hrs work aside
My dad spent his entire life selling Machine Tools. He was the go-to guy for every machine that moved west of the Mississippi. If you had a flarod that needed a .03 widel he could tell you the exact machine and have it on a flatbed interior shop as quick as can be. Some of my favorite memories where the machine tool shows where each manufacturer would demonstrate the latest and greatest of their product line. It never cease to amaze me how you could take a piece of metal and with a little creativity in the right tool anything's possible! Huge kudos to the radial engine crew!!! It is so refreshing to see brains put to a positive purpose. Keep up the great work, and thank you for sharing it.
Very, Very cool. You are a talented machinist, but it takes even more knowledge to know how to make everything work. One of the neatest most advanced do-it-yourself projects I've ever seen. I make a lot of stuff by myself, for myself but nothing as advanced as this! Mind you I don't have a full machine shop. Yet. Props bud, incredible build.
The dislikes are from the Rotec staff in Australia. They don't like it when someone scratch builds something that is far superior too their screaming piles of shite! 0_o
Quite simply, this engine is a design, engineering and construction masterpiece, a true work of aviation engine art. I would love to see this engine in a small self-built aircraft, it's natural home!
This is by far the most stunning piece of automotive enginerring art i have seen, its just beautiful and the attention to detail is greatly appreciated by people like me. Please keep it as a work of art on display, it does not need to be used for any other purpose. you are obviouly a living legend, considering you made this, because you can !! congratulations Sir Arnold, you are "De Man" !
WOW!, Arnold, You are Definitely Da Man!!!,,, I am in the automotive business with several franchised repair shops and always try to look at relative things and other things like this. You have really created a beautiful motor that would be far superior to any other I the manner it was constructed!!!!.... Great Job Arnold!!! Great Job!!!
I've always had dreams of having such a shop available to create some of the automotive adapters I've thought up. You get an enthusiastic thumbs up from this wannabe machinist. I'm experiencing serious envy pangs! lol
Nathan Dean I've gotten more free lawnmowers out of spring cleanup that won't start because of rust build up on the coil that anything.3 screws a bit of 200 grit sandpaper and made my self $40.
... recently, on FB, a video has been making the rounds of a carpenter made 9 cyl. radial engine... the maker was able to take all the parts off and show/explain what they did and how it worked... that was cool... and it made understanding this piece of work all the more satisfying...nice work this, very nice work...congratulations...
For those unfamiliar with vintage radial engine design, the rockers were in most cases exposed and yes, the pilots were often covered in spewing hot oil.
@@sdavrider aviation rotary engines are different to automotive ones. The Wankel rotary came after the aviation rotary became obsolete and was replaced by the radial. Here's a link: en.wikipedia.org/wiki/Rotary_engine But yes, I did mean to write radial, as this motor does not spin with the propeller like the redundant rotaries used to do. Will edit my comment.
It's a work of art. Not just because you've made such a smooth running engine, but the extra effort in things like the copper intake manifolds. I agree with everyone else, this should be bolted on to some kind of small aircraft. A double row unit is obviously a lot more work, but could give it the edge as a "vintage" aircraft engine. During WWII, Australia was having trouble sourcing their own fighters to defend the northern borders, so they designed and built their own. They took a trainer known as the Wirraway, that looks like a stubby Mitsubishi Zero, and reworked it to become the Boomerang. From first sketch to flying prototype took 6 weeks. They strengthened the airframe, added a pair of 30mm machine guns, and in place of its 7 cylinder radial engine, they fitted a double row, 14 cylinder radial that I believe also powered the B-17. It could climb vertical to 20,000 feet, something neither the Spitfire, Hurricane nor Mustang could do.
So modest!! First you machine all the parts, then you put it together...now let's start it! There must have been hours and hours of designing and problemsolving...you sir are amazing!
Wow, what a work of ART! I just love it and think you're not only very industrious but also ingenious...Bravo! Thank you for sharing your creation with the world, you should be forever proud, and I hope your kids appreciate it and care for it for years to come. Aloha...Chuck
Arnold, I am a Senior ll R&D Machinist in the USA, and I share your Fascination with the Radial Engine!! I am very happy for you in bringing your Design to fruition!! You have done a Beautiful Job with this Engine, and I am just ecstatic about this!! I wish that I was Setup with a good Machine Shop and Welding Equipment in my Garage. It has been a plan of mine to make my Grandkids Minibike and Go-Kart’s, etc. when I Retired.... however The Lord 🙌 saw fit to allow me 😉 to develop MS (Multiple Sclerosis), and I’ve been Disabled by it, for 19+ Years now... and I cannot afford to Build a Good Shop now, and I won’t likely ever be able to fulfill that Dream.🤧 Anyway, it is always fascinating for me to see the Machining that Machinists across the World are doing, and compare any things at all, that are different from the way that we do things here in the USA. From your short Film anyways.... I haven’t noticed anything that differs from the way that we work. What Grade of Aluminum did you use for all of these Parts, in particular, the Connecting Rods? Do you have any Future Plans for your Engine, or will it always be on it’s Engine Stand? I used to Minister to the Seniors in our Church before Developing MS, and I was told a Story by a Senior Friend from our Church, many Years ago, about how he used to be a Mechanic for the Local Airport, Working on Crop Dusters, and he told me how he had a Big Aircraft Radial Engine, on a Stand like you do, except he made the the Bottom of his Engine Stand, with Steel Skis so to speak, with the Front of his Stand, having Radiuses in front, like Skis do, so he could move it around easier. He told me that the Pastor of his Church was visiting him one day... and he took him to the Garage where his Radial Engine was, to show him what he had been up to.... also I think, because he was somewhat proud of it. The Pastor, Roy Huckaby, stood in front of the Engine, some distance away from the Prop. Now Tom, had a Prop mounted on the Engine, Similar to you have.... and he started the Engine, with himself, standing behind the Engine, on the Steel Ski’s, and he was Revving the the Engine periodically, as people do when they are running an Engine.... and he Revved it more and more, end he eventually Revved it so High, that the Engine, mounted on the Ski Like Bottom of the Engine Stand, pushed itself several Feet forward, right up close to his Pastor, Roy Huckaby, and the Engine, on it’s “Ski’s,” stopped just short of “Mulching” poor Old Roy Huckaby, and scared the Living Daylights out of Tom Azevedo, realizing that he almost took the Life of his Dear Friend.... and that was the last time that Tom ever started up that Engine on his Stand..... so be careful!! PS. Sometime before he had it on that Stand this last time, he had made a Flat Bottomed Boat, similar to those you have probably seen being used on the Florida Everglades. Now you see, we are in Prime Farming Country... and he had told me that when certain Crops were being Heavily Watered, he would take his Flat Bottomed Boat to the Field, and Race it all over those Fields being Flooded! (They had to have just recently been Planted.) It just realized, that what seems like it would be a more complicated Engine to Build.... it would be much simpler to Manufacture, based on the Fact that you wouldn’t have to Make a much much more Labor Intensive and Technically Challenging Looooooong Crankshafts that the In-Line Engines require, and that would be a tremendous Weight and Time Savings that the Radial Engines had over many of the other Engines!! Do have a much longer Video covering your Design of the Engine, (You likely Designed it all on CAD right?) and your thoughts as you we’re going along in this Machining Adventure.... that also let’s us hear you thinking out loud, and Narrating what you were Learning about the Radial Engines, in your earlier Stages, etc.? Thanks so very much for sharing your Engine with us. Personally, enjoyed it very, very much!! 👍 ⭐️⭐️⭐️⭐️⭐️ Thanks for sharing your Engine with us! I personally, enjoyed it very much!!
Blackiceman225 How can you compare your built bike to this engine? I jumped over expecting something special but instead I got a bought bike. What a disappointment!
Bob Ordewald sorry Bob but you didn't understand the context... Groutaone is known for his Honda Cr500 Videos and when I saw his comment, I just wanted to show him my bike :D So don't be disapointed ;)
Arnold Sir, You have created a beautiful piece of engineering jewelry ! My hat is off to you ! I am a VW connoisseur, and always have been fascinated with the radial Engine ! ABSOLUTELY GORGEOUS !
I think you may have unleashed something locked away in those parts....That thing may try to invade Poland and annex Sudetenland if you aren't careful...
As a metal parts manufacturing technician, my congratulations for your work on this star engine, I think you have to have a great experience in this area. regards
Arnold you are de man!!!!! That's an awesome display of talent. It would be cool to see someone build a plane for your engine and see it fly. Keep up the great work.
Why Terry? VW sorted the oiling out with their engine, why any different here? I don't get why though the heads were machined to exposethe rockers?? Maybe to make it look older??
Ben, I was wondering the same thing! I came to the conclusion that he must have Rocker Covers and Tubular Pushrod Covers, lest you would Lose Oil, and render a potential Pilot, Blind in a Short Order! I just came to the conclusion that he probably just wanted to watch it Run in the Naked sense, and would deal with it later. However... I am just now realizing that I have been very surprised to see other Radial Engines with the Rockers exposed. A competent Machinist wouldn’t overlook that situation... and he definitely is a Competent Machinist, from one to another. He has done a beautiful Job!!!! 👍⭐️⭐️⭐️⭐️⭐️
In the "old days" they had oil cans. Joking but even the old steam engines had litle oilers or ports. You have to oil them periodically. I don't think this engine was ment to "fly" more a work of engineering art, and a dam good one.
with 7 turbos plumed onto this thing and the 7 intake pipes feeding into the carbs............it would be a work of art....I would just sit and looks at it for hours...
+Gavin Windsor that running on something like nitromethane would be some savage piece of art work, I'd go deaf with something like that, the lines on that would both be functional and beautiful at the same time
It is a dry dump, sort of. In this case there is a pressure lube pump a separate oil tank and a oil scavenge sump that drains back into the oil tank. It’s functional the way is but could use a little more development. Say like an oil cooler and a scavenge pump or a two sided pressure/scavenge pump. As long as you don’t go inverted with it, it will work just fine.
What a great piece of perfect work!!! I love the sound of the old "boxer-engines". And now as an radial one. Has anyone ever tried that wonderful engine in an aeroplane?
You must be the calmest person ever. I would be running up and down my street like a maniac shouting "It works!! It F'n works!!" Until my neighbors call the police.
What do I love about art? It's completely unnecessary and time consuming, and yet it is something entirely worth living for! There's a magic to it. And this is no doubt a work of art.
@@MidwestFarmToys The VW engines that the cylinders were taken from do have oiled top ends, I'm not sure why this guy didn't have valve covers other than it would have been a lot of extra work. I wouldn't trust this engine to operate more than a dozen or so minutes at a time, let alone being used in anything like experimental aircraft.
Beautiful workmanship. Incredible sound. Would love to see this engine power a home built experimental aircraft. I am a retired heavy equipment mechanic , fabricator, pilot. I know quality work when I see it. Good Job.
Total loss oiling? Radial engines used dry sump systems with scavenging pumps to recover the oil from the lower rocker boxes and crankcase. Rotary piston engines, where the crank sat still and the cylinders and crankcase spun around it, are a total loss system, using massive amounts of castor oil that often gave the pilot the runs. Nice video, who needs an A&P like me!
+mike klaene There are several ways to do it. You can either build a small, single-lobe exhaust and intake cam for each cylinder, and gear them all to the crank so they spin at the proper rate (1/2 that of the crank), or you build two larger "cam-rings" that run around the crankshaft, inside the main housing (again, geared to 1/2 crank shaft speed). There is an intake ring and an exhaust ring, each with a single bump on it and running alongside each other. As the crank turns, the ring spins around, the lump hitting the pushrods and lifting them at the proper time. Since it's spinning at 1/2 speed, on the first revolution, the intake bump hits the intake rod. On the second, the exhaust hits the exhaust rod (you can imagine them being on opposite sides from each other, although in real life the lobe separation angles are similar to any engine's. I gather there is some way of using mulitple lobes on each ring, but I'm not sure how that works. I guess you'd just do your math and gear it down even lower. You can see the cylinders, housing and pushrods at :35. The cam rings would run around just underneath where the pushrods meet the housing. Or at 2:17, when it's running, you see the metal housing, and the rods moving? Imagine just under there, running around the inner circumference of the housing, there is two metal ring, and each time a lump meets one of those rods, it lifts it. Each runs in a slightly different track, to keep them separated, so the intake only operates the intake rods, and vice versa.
Joelee Finn, dry sump. Scavenge oil pump collects spent oil to external tank, gets pressure fed back to motor. Except to the valve gear that appears to be uncovered for oiling by engine. Grease it up before takeoff!
Impressive in design and execution. It's also nostalgic for me since I once owned a '66 VW. I wish I had it now. What a car all around and it was a relative beast in snow. Seems like this creation would need valve covers to make it practical but otherwise a wonderful outcome.
curious if it has been dyno tested? Any ideas as to how much power it makes and weights? Would be really cool if it was, then put a turbo or two on it and see how it does😊 maybe even some water/meth injection😈 then see how much it makes😆
Brent Miller I don't think that is a valid comparison. An oilfield engine is extremely overbuilt to a purpose by industrial manufacturers, and does not see anywhere near the RPM, heat expansion and cycling, or load that this engine will see compared to it's size. This valve train will suffer rapid wear or even total seizure, if not covered and lubricated. This IS a one off prototype that has not yet been endurance tested....
it has to be a total loss oil system, no way to recover the oil from the lower cylinders without using a vacuum pump. Originally radial engines used castor oil, pilots would be very eager to get back to their parking spot after ingesting for a couple of hours😄
Mark Watrous correction: rotaries are total loss radials are dry sump (oil return pipe is in the lower gap between the cylinders below the master) check google if you don't believe me
cartmanrlsusall Back about 1970 Gulf sponsored a Ford GT at Sebring. The oil cans said Single G but the sweet aroma of the burning oil said castor oil.
+Mark Watrous: Yes, radial engines use a dry-sump oil system since there is no place to put an oil pan. An internal oil pump would scavenge the oil from the crankcase & send it back to an external oil tank. Then a tank-mounted oil pump would pump oil through a filter, then a cooler, then back to the engine where the other side of the engine oil pump would send preszurized oil through the oil channels. The cycle would then repeat itself again, over and over and over, and so on, ad nauseum.
Great job! I was hoping to see the internals spin before completion. I will look for other videos now that you have peaked my curiosity in how the transfer of energy takes place along the crankshaft.
