Hello sir, I've 2 doubts, 1st is it possible to run the engine with just 2 cylinder, and 2nd, will all cylinders speed is same or different, in piston engines, humble request u for clarification sir, thank you

We get our Lycoming's rebuilt/refurbished by these guys. Their work is impeccable and the little things they do make all the difference. When an engine is shipped to us, it is packaged well enough to withstand Armageddon. Moisture desiccant packs, plastic wrap...you can stick it in a corner and get to it months later and it comes out looking like it left the factory. Just high quality work. And they run like a scalded dog. I would almost prefer a brand new engine go through their process first before we used it! lol

@J.C. Kohle Real race engines are built to this level of precision and higher yet. Aircraft engines are by no means high performance.

[@theprofessorfate6184]

@@johngnipper8768 they're like most horizontally opposed engines, long on life, low on performance. Even still, if they were so great, you wouildn't have to rebuild them just for sitting a couple of years. That's proof of why they're really crappy.

I am here just pissing my pants at the incredible attention to detail that Chris adheres to. This perfectionist has no place for compromise in his shop. Barring absolute abuse, I cannot imagine the pain and anger he would suffer if one of his rebuilds would fail under normal use. A craftsman after my own heart !!

I doubt that has ever happened.

[@sailsunfurled]

Found Chris from your channel and its only about an hour drive from Gulf Breeze. I am rebuilding a Lycoming IO-360 angle valve 200HP for my RV-7A project. I dropped off all parts needing machining yesterday at Air Worx. I feel real comfortable after meeting Chris and his crew. Thanks Bryan for the channel and episode on Air Worx

[@ExperimentalAircraftChannel]

You are VERY welcome! Thanks for watching and taking the time to comment here! :-)

[@scotabot7826]

Franklin's have a beautiful sound of their own, and they are the smoothest running engines ever designed. Knew a guy with a 108-2, and there was absolutely no vibration at all. If you have never been in a aircraft with a Franklin, you need to take a ride, you will be amazed!!

This is amazing work ethic & passion. Makes me want to build an airplane just to have one of Chris’s engines! Thanks for this great interview Bryan.

[@specforged5651]

I’ve been a corporate turboprop and Jet pilot for years and being a gearhead myself, I would say I know a considerable amount about aircraft, systems and their powerplants. However, I could watch guys like this all day long that are extremely knowledgeable and true artists of their craft. Always looking to learn more no matter how much you know or think you might now. Thanks for sharing! Awesome!

[@idekav.]

pretty cool! im a 17 year old private pilot and am trying to learn all of the little ins an outs of aviation including the mechanic side the business side all of it man very interesting stuff.

[@specforged5651]

@@idekav. Keep it up, you can never EVER know enough about your aircraft, it’s systems (powerplant, hydraulic, electrical, environmental systems), it’s little idiosyncrasies (they all have them), it’s behaviors....what I would call personality and the list goes on and on. Never stop learning and never feel complacent with what you do know. If there is one piece of advice I feel to be the most important it is exactly that....never become complacent and never extend your capabilities out of your personal limits. Set them and abide by them religiously. You can feel uncomfortable, we all do and that is how you learn and become better. Your gut will tell you if you’re pushing to hard or don’t feel safe in a particular situation. When that happens, and it will many times....First fly the airplane, then diagnose and resolve the situation if possible, commit the situation to memory and educate yourself on that particular event. Take them one at a time and focus on learning and becoming better. In addition, rely on more experienced pilots, your instructor, manuals/text and don’t be afraid to say you don’t know and ask. If you run into someone not willing to help, of which there are very few anymore, move on, that person was not someone you want to learn from and was probably not capable of answer your question or helping you in a positive way anyways. Keep it up and soak up ever possible piece of knowledge you can pertaining to your piloting skills, aircraft, ATC, airport operations, maintenance (a big one I feel gets overlooked) and the list goes on. Stay safe, stay within your abilities and strive to learn and you’ll be very successful. Good luck!

[@michaelmartinez1345]

Xlnt video!!! I always wondered WHY one of the instructors that I had, going through A&P school (many years ago) RAVED about the Franklin engines so much... Now I know why... This shop seems to be an Xlnt place to do work like this and they seem to be very well organised, clean and knowledgeable... Great program!!!

Thanks for the great video on engine building. The Franklin conversion for the Cessna 172 seems to have been a popular upgrade in horsepower back in the day. I have a vintage 1963 172E model and before purchasing it I was looking to build a Van's RV-9. There is a lot of good crossover information regarding Legacy Aircraft and Experimental. I really enjoy your channel. Keep up the good work. Oh, and Chris is a machine, just the size of him should keep the Riff Raff out. He really knows his stuff.

i like the rod boring idea on the big end very nice... and love the diamond reamer for $1000 for the valve guides... just wow cross hatch... so nice that will hold oil in the angle cut.. a great thing is to cut the OD of the valve guide to fit into the head and not keep cutting bigger every time on the head where the guide go's like he said keep cutting the head until the head where the valve guide go's until it is so big you cannot get a valve guide big enough now the head is junk ... remember around 2000 hours or less you got to rebuild the engine .... how many valve guides can you keep cutting into that head ??? he is truly the best i have seen on machining engines i have seen...

Semper Fi from Stache Air, great walkthrough of your shop and what you do. I will post a link on my Facebook site as I am a DME now.

[@doesntmatter3068]

Being a pilot (strictly for fun) for over 20 years and a machinist for over 30 years, this guy is doing his job very right. For the last 16 years I have been reman'ed jet engines. When you constrain a part then machine it, it will be that much better in performance. This is the way most parts I do get machined, in a constrained configuration. When he is talking about tolerances, he dead on. 10,000 of an inch, most people can't comprehend what this is. it is written ".0005", if you took an inch and divided it into 2,000 divisions, this would be the sizes he talking about. A human hair is appx. .004 - .007, .0005 is 8 -14 times smaller! I would love to come work there after I retire! Very nice shop indeed!

[@hokehinson5987]

Outstanding company! Outstanding Owner/manager. His ethics are difficult to find in today's marketplace. A good machine shop and builder are very difficult to stumble upon today. Our experience is in automotive. The mindset in the marketplace is git-er-dun cheap & fast. Also the strength of any shop depends on ethical management then on qualified skilled employees and necessary equipment to provide quality results. Many places employ poorly trained employees working on equipment needing refurbishing, working towards production out with mediocre quality. My comments relate to our experience in the automotive arena. Luckily our small town has a top grade machine shop. The big corporate money men rebuilders in our experience turn out products that are borderline just to eek by warranty. The gentlemen in the video is an anomaly. Bet his employees are proud to work for him. I sure would. The newer automotive engines are engineered to borderline failure. Rebuilding / refurbishing has changed completely from the old forgiving cast iron heads & blocks of the pass. Think about it we drive engines in street cars with the same technology used in formula one racing years ago. Cheers

You sold me on Franklin engines. There's a place in Ft Collins, CO that sells a 125 hp Franklin Kitfox engine package and STC packages for several registered aircraft (Stinson, Bellanca, and various Cessna)

[@ExperimentalAircraftChannel]

We saw that about 2 years ago. I'll try getting in touch with them "again." They did not respond from the initial contact years ago. The only ones that we are aware of selling new (NOS - New Old Stock that is) would be Southern Aero in NC. I have spoken with Doug Still recently. They have a phone number. They answer. :-) And Franklin Parts in TX. Susan Prall. She has NOS for the Franklin as well. She has a number. She answers. :-)

[@lloydrmc]

@@ExperimentalAircraftChannel so these are STC packages they sell? Ft Collins would save me on shipping, though the other places would be workable.

[@ExperimentalAircraftChannel]

[@paiggey]

What I don't get is when you overhaul surfaces like the cylinder walls, how do you get the bore up to manual spec if you've removed any material? In a similar vein What happens if the piston head has marked the inside wall beyond that manual spec?

[@ExperimentalAircraftChannel]

Adam Paigge from what I understand is the cylinders are 1 complete unit and the area the piston moves in (the cylinder itself) is actually a steel SLEEVE. This SLEEVE is removable under heat and a set screw. So it this doesn't meet spec then it is simply removed and re-sleeved. Thank you for watching!

[@marcs990]

What’s the average price difference from getting a new engine to getting it overhauled by yourselves. Thx in advance 👍

[@MRxMADHATTER]

Franklins are badass.

[@steveb7310]

These guys do it right.

[@HybridVW]

Two big points that he missed differentiating the case from brands L and C- the Franklin has a top case cover that can be easily removed to do a visual inspection of the inside of the crankcase (rod bolts, cam lobes, etc.). The other great thing is none of the cylinder mounting studs are "through bolt" style where the same bolt is used to hold down opposing cylinders AND clamp the main bearings in place. Mike Busch has several articles about the risks associated with doing top overhauls on engines that use a "through bolt" style construction.

[@southjerseysound7340]

Yeah you don't have to worry about it on a Franklin. I did a top end on my maule because of corrosion when I got it and she ran well past tbo.

[@ThePudgie123]

Hi...just watched your "live" crankcase vid, but couldn't find a way to LIKE it...but I did. Was curious how you keep the grinding wheel round...let alone true. Have you ever had one explode? ...my dad was a T & D maker in the '40's and said it can happen.

[@ExperimentalAircraftChannel]

@The Pudge123 Hey! Thank you for watching! So... Not sure how you missed it...but somewhere in the "middle" of the video Daniel does in fact "dress" the stone. And also lastly made sure the "Radius" was made true with a separate tool that swiveled around to create I believe is a 1/8" radius on the edge of the wheel. He also informed me when finished working, they turn off the "coolant" and let the stone "air dry" for a few minutes before shutting it down. Keeps the stone from getting water logged. Maybe that is what can make them come apart? See you in the upcoming videos!
