Prop Overhaul

[@kazflight]

This is exactly what I was looking for! Thanks for posting, Bob! Most that pop up talk about why you should overhaul and not the how.

[@reedcustomcabinetrywoodwor8780]

WELCOME!

[@trickcyclists]

I really enjoyed this. What a pleasure to watch a skilled man do his work. Tony obviously enjoys his job and id equally obviously good at it... I hope Sensenich look after this bloke, there's not enough of them in the world. Thanks for posting Bob.

[@Chief351L]

Tony is a Propeller Beast and I thoroughly enjoyed watching his work. I sure hope he has someone there that is soaking up the knowledge he has!

[@markoda8455]

Tony is a real master. I never realized how much went into a prop overhaul. Thanks for sharing.

[@gremlin1396]

Would have been nice to find out what the outcome of that gouge in the prop was and what was done to repair it.

[@chrismarkovic3211]

Absolutely loved this video! Hats off to Bob and his skilled work!

[@ldwithrow08]

Outstanding to see a true craftsman at work!

[@StonyRC]

Lawrence Withrow - yeah, I think so too. A lifetime of experience and a real and natural "feel" for the work is the difference between a tradesman and a craftsman.

[@vincentmiconi1869]

Fantastic workmanship! You have a great skill.

[@StonyRC]

Incredibly interesting video Bob - I'm not an aviator but I just love to find out how things work. Best wishes from the UK.

[@johnfitzpatrick2469]

Thank you for demonstrating the measuring instruments and criteria in your profession.

[@andrewo763]

at 2:57 sounds like he is talking about work hardening rather than annealing, which is heating metal to reduce internal stress.

[@jackx4311]

It astonishes me, the number of pro engineers and mechanics who call that annealing - and also the number of people who confuse the terms 'hardening' and 'tempering'.

[@MattRogersdesigns]

At 2:50 he incorrectly calls the metal process annealing. I am hoping he meant to say work hardening as that is what happens when the prop is bent back and forth. You could anneal the metal back to a softer state using a carefully controlled furnace, but obviously that may also require a heat treatment as well.

[@ele4853]

I wonder how much it’s charge for this intense labor task. The work of an artist 😊

[@dlfabrications]

what wing profile are propellers, CLARKE type? NACA airfoil

[@mamulcahy]

It’s a joy to watch a professional work!

[@envitech02]

I didn't know there's so much work involved in the servicing and calibration of propellers.

[@hemersons.junior7645]

Hello, please, what is the correct time that the piece has to be bathed in alodine? does any FAA manual show the time?

[@natopeacekeeper97]

You would never guess the insane amount of expertise needed to do this to a propeller!

[@Graham1904]

Great video. What was the cost of this prop overhaul?

[@conantdog]

Great video, great Craftsmen interesting jigs and templates. I really like the twist jig with a bubble level . Tony looks like he does excellent work and enjoys his job ✈️👌🛠️😁

[@patbarrett9263]

very interesting, I didn't realize all that went into a prop overhaul, I'm surprised they didn't magnaflux the prop before they started working on it.

[@jimwells4240]

Just for the record....the prop is made of aluminum and you don't magnaflux aluminum. Dye penetrant, eddy current, ultrasonic, or x-ray inspection is for aluminum.

[@bulwinkle]

The question that comes to mind is not about the process, but is what educational and employment path leads to such a highly specialised trade? I'm willing to bet that overhauling props was not what he left school or college wanting to do.

[@KB4QAA]

Maintenance job paths: 1. Go to A&P school and get your license. 2. Go to work for an overhaul company/manufacturer and learn OJT. 3. Join the military. The best choice is to go to formal school and get licensed since this will give you a well rounded education and the flexibility to obtain varied work.

[@spenner3529]

I wish I had a prop for Tony to overhaul.

[@GrummanTiger1]

Very useful (and fun) video, Bob - thanks!

[@darylmorse]

Amazing skill. Really impressive!

[@luiserodriguez7442]

Awesome video, thank for share,!

Should I be worried about my balsa prop?

[@wesbrackmanthercenthusiast4695]

does this apply to wood propellers

This is a cool video. For a non pilot I learned a lot.

No NDT? That's hard to believe.

[@Desertduleler_88]

I'd like to see how prop overhaul is done on constant speed props.

[@1shARyn3]

and I on carbon props

[@bvcxzgt5451]

Of course it is largely overlooked. Most of us can't see the runway without looking past it!

[@bvcxzgt5451]

So is this a video about a guy with a nick that could have been faired out instead paying thousands to have his prop measured extensively, sanded, and given back to him?

[@pw309]

I bet you're fun at parties

[@bvcxzgt5451]

@@pw309 Not very, no.

[@airgliderz]

A "nick" as you serm to minimize can be a vary serious issue, especially on a metal prop with lots of hours, obviously you did not watch the video

[@deeremeyer1749]

Looks like that prop grew a BUNCH after it was removed and blasted. Changed pitch dramatically, too. Then it shrank. Then it grew and finally shrank again.

[@davidl.579]

So much goes into an aluminum prop inspection wise. I do not see this level of checking in a wood prop. Why is this?

[@airgliderz]

Wood does not fatigue like metal. A wood frame if kept in good condition can last forever, where meta has a limited, albeit long lifespan.

Thank you 👍

[@PDZ1122]

Add 2:15 he is using a pencil on aluminium alloy. Thought that was a big N0-No.

[@terrybaremor6361]

I noticed that as well, the lead in the pencil will cause it to crack if left, however he did polish the blade again after placing those marks so probably ok.

[@walkaway6353]

@@terrybaremor6361 Pencil's are graphite not lead.

[@vilsiran]

Don’t use a pencil on the burner cans in a jet engine. Combustion chambers.

[@smaze1782]

What a great video.

[@gremlin1396]

I guess if your prop comes apart we will hear about it on the news

[@sheridanbaldwin8629]

Almost like doing a boat prop some what I guess

[@yeagermcbipper9008]

So Tony died years ago from all that dust he inhaled while grinding metal. That shop was a disaster area, no PPE.

[@deeremeyer1749]

Given the impossibility of "magnufluxing" aluminum and how difficult it would be to use dyes to crack-check a propeller without stripping it entirely of paint and possibly "scuffing" the polished surface with something to give the dye something to "bite" and flow into, I can't see "overhauling" any propeller I haven't owned since new and have constantly and consistently inspected and kept polished and paint-free since Day 1. Way too easy for some clown "upside down" in his new "toy" and needing to dump it before the bank takes it to do a "DuPont overhaul" or "refinishing" polish job on a junk prop that can easily have any nicks or scratches carefully filed/filled to make it "mint condition" to the casual observer. Any prop that is out of balance or bent is damaged goods. Period. Even with no nicks or scuffs or scratches. And you don't "straighten" aluminum and get it back into "shape" because it stretched and strained on the outside of a "bend" and compressed and work-hardened on the inside of a bend even after that bend is "gone". I don't give a shit how "inexpensive" or "comprehensive" a prop "overhaul" is, you don't and can't compare it to a NEW PROP if you have a brain in your head. You're not getting a NEW PROP and unlike an ACTUAL OVERHAUL of say...ENGINES where wear parts are REPLACED to return critical clearances and surface finishes and engine performance and durability to BRAND-NEW LEVELS, you can't "rebuild" a part by taking material off it and not weaken/compromise it in the process. Its also impossible to properly and perfectly balance ONE PART of a rotating assembly like that in any kind of engine-powered powertrain in a vehicle doing a "static" or even "dynamic" balance of one part at a time and have that assembly be "balanced" once everything is assembled and in operation. Buy a balanced reciprocating/rotating assembly for your "hot-rod" or have a quality machine shop do the work balancing new and/or used parts and see if they're "balanced" one at a time but not assembled. But hey, AIRPLANES ARE SO EXPENSIVE TO "OVERHAUL" YOU HAVE TO SAVE MONEY WHEREVER POSSIBLE AND MOST OF ITS AN FAA/MRO/A&P SCAM TO ROB PRIVATE PILOTS BLIND BECAUSE THEY'RE ALL JEALOUS OF PRIVATE PILOTS AND THEIR AIRPLANES! Yeah. When a government agency regulates something or some industry or some group its never because of the potential for those government employees doing the "regulating" or their friends or family membrers to be injured/killed when somebody who isn't qualified/certified/motivated to maintain, service, repair and operate a "privately owned" motor vehicle on or in public "highways" and decides to take the "cheap" and "easy" way out ends up crashing or causing others to crash when their personal transportation suffers a catastrophic failure or even just a momentary "glitch" that takes his or her eyes off the "road" just long enough for them to "lose control". The comments I see all over the internet from supposedly "responsible" and " successful" private pilots who think FAA-mandated inspections and FAA-recommended or required "overhauls" are something anyone could or should "opt out" of or should have done as "economically" as possible to "save money" so they have more to spend on UNNECESSARY and FRIVOLOUS gadgets and gizmos like "glass cockpits" and all sorts of high-tech bullshit their rating, aircraft, flights and skill levels not only don't require but are apt to make a "professional" private pilot think he or she is much "safer" and "better equipped" to prevent and handle "emergencies", the more I wonder how and where they worked in their "careers" to make enough money to play with private planes without having any rules, regulations or responsibilities in THAT aspect of their lives sufficient to demonstrate the importance of "playing by the rules" in their personal, play-time lives. And the ones that are playing "charter pilot" on the side flying paying or even non-paying but non-pilot passengers around the country because they want or need the extra income/experience/ego-boost to keep flying that play-toy or purchase the next one or pay for more lessons to add endorsements to their license sure have more balls than I ever would have given that I'd at least value my OWN LIFE if no one else's. And the thought of a primarily simulator-trained "pilot" thinking passing a couple "exams" an "instructor" or "flight school" they're paying to GRADUATE THEM so they can FLY makes them an airplane expert on the GROUND enough to know how to operate and maintain an airplane properly and make "maintenance" decisions from choosing a "good" mechanic/MRO/consultant to what to "defer" and what is or isn't "necessary" or "too expensive", when they probably can't or won't check the oil or change a tire in/on their "ground transportation, makes me glad I don't live anywhere near an airport. Seriously, if you really want to fly and don't want to be bothered with TBOs and all that required "scam" stuff, why bother getting a pilots license in the first place? You don't need one in controlled airspace, you can buy way "more" airplane for "cheap" if you're okay with cutting corners and "deferred" work and rolling the dice on an "experimental" plain that's certified by the FAA for use by certified pilots as far as that "type" goes but sure as hell doesn't need to be certified for a part-time "pilot" flying in uncontrolled airspace and doesn't even need to be insured if that "pilot" has saved enough money to buy it outright and REALLY wants to "save money" not making payments and paying full-coverage insurance premiums as a new licensed pilot in a financed airplane. Shit, its not like 90% of private pilots aren't spending 90% or more of their flight time in uncontrolled airspace anyway and they sure as hell don't let little things like regulations and recommendations pertinent to their airplanes boss them around. Why be a FAA-licensed and "qualified" pilot in an airplane that gets its FAA-required annual inspection by an FAA-licensed MRO/A&P who will a "qualified" pilot run the show in the shop or goes to a "consultant" with the inspection form and lets that third party who hasn't laid eyes on the plane make the call on what "needs" or "doesn't need" to be done? Think how much money those new-pilot "experts" would save just going with the "fly by night" approach from Day One and just going from Flight Simulator to the pilot's seat and from KZbin "overhaul" videos to amateur A&P.

[@terrybaremor6361]

Sounds like a broke and frustrated pilot that wants to fly but can't afford it, there is nothing cheap about airplanes.
