Just Got Shafted

[@claudemorehead4529]

Keith, I have been watching for a few months. I work as a tooling machinist for an aerostructures company. Propellers may be a common item, but they do different jobs. I enjoy catching little tricks that you may or may not realize that others are picking up off or your videos. Keep doing what you are doing. You are an asset to the country.

Good work I like your style people don't take time anymore nice to see someone that is more than just getting the job done you do it and it's right when you finish.

[@KeithFenner]

The electrolysis That causes the pitting on shafting and other propulsion components, is more prevalent, with non bonded items and areas surrounded with stale waters / water with little motion, like inside stern tubes. We get alot of propblems with people that run boats from down south with Aq 19 shafts installed on them, up hear in the colder waters, the best material all around is Aquamet 22... I believe marine shafting when installed and maintained correctly, sould out last the hull...

[@KeithFenner]

I don't do prop work hear, except bore, key and lap fits. There are about a half dozen prop shops in New England, I leave it up to them, I just handle the rest of the propulsion system, shafting, struts, rudders and skegs.

The thoughts expressed at 3:48 are why I love these videos.

Lapping in works. A buddy of mine used to race go-carts with 5 horse Briggs. He'd lapp in the flywheel /crank taper end and do away with the key so they could move the flywheel back to advance the timing. No key, just a good lap job and cinch the crank nut down. Never moved with those old engines screaming. You are a True Craftsman and not from Sears either!!

[@ypaulbrown]

Lewie, I worked with a guy in North Carolina and we made offset keys for racing go kart engines......tinly little things,,,,,,we made thousands of them for a company called Williams in Madison.......

[@lewiemcneely9143]

@@ypaulbrown Thanks, Paul. The best I can understand it was sort of a freehand deal. A key like you made would work after the engine got 'dialed' in. MY buddy that did it said it was a dial indicator after the lapping and then put the crank nut on and torque it down and that was it. The crank was on to stay. My old saw had to've been done that way. It had hideous compression and was happy when squealing instead of just screaming. And it ran for YEARS like that and would again but the flywheel will NOT come off. The buddy's son worked for a BIG outfit and had access to all their equipment and even with their big pullers it would not budge. The guy I got the saw from said with a big grin that his son had 'set it up for me' and he knew I knew how he was. He 'set up' a Farm Boss that was plump scary and my saw would put that one under the bed. One day we may know and we may never know but I DO know that that 45 was a piece of work for a LONG time! GBWYou!

Thats the price of not following through with a project of repair! Thanks for the comment! ;{)-----

[@howardtoob]

Great video! May I ask what your favorite 4-1/2" corded grinder is? I buy expensive tools so I only need to buy once and I'm looking for a 4th angle grinder. "Hobby" machinist BTW. Thank you 👊

[@strongandco]

That nasty case of hammer rash says it all!

[@zbeast]

mad props to you. :)

[@nitro105]

I had to do a taper and key repair on a transfer case in a heavy forklift and found that in the past the gear had sheared the key and turned on the shaft and someone just replaced the key and not cleaned up the taper. the shaft was shouldered behind the taper and the gear bottomed on that before the taper made proper contact, it was a mess.

[@g6qwerty]

Looks like the last person had a problem removing the prop as well.

[@jsmarine316]

Much respect to you. In your experience what would you consider the lifetime of a 2" aqua-met 19 shaft in salt water? I am surprised to find pitting in the stern tube area of my 8 year old prop shaft. Keep up the great work. JS

[@Pusher1944]

This is an old video I know, but I just found it and I have an off topic question, if you don't mind. That is a really big prop to me. What kind of horse power would it take to turn that thing? I'm a retired heavy truck mechanic and I'm sure that prop did not have a Chevy or Ford in front of it. More like a Detroit 8V-71 or even a 12V-71, 92 if its "newer")? (92s are new to me).

[@Mentorcase]

Stainless nuts galling is true horror the cleaner the joints the worse they gall, if i have to use stainless nuts I always use good copper or zinc lube.

[@thomasb1492]

what is the blue you put on top of the key stock 13.08 that you you said now its ready?? lube or locktight??

[@johnferguson7235]

It's a type of paint that shows where the prop is fitting tightly to the taper on the shaft. The friction of the two surfaces is what transfers the torque from the shaft to the propeller. Keith is showing that the prop and shaft aee in even contact over the entire mating surface.

[@boxroller5]

Keith, from about 10:30 to 10:45 in your video, behind you on your right side what are those wooden toolboxes? I have an identical one and a smaller size and I've never seen another one. My grandfather gave them to me a few years ago and he had them for his whole machinist career and paid some decent money for them in the late 50's I believe. Who makes those? Any idea where I could find more information on them?

[@mrbluenun]

Hi Keith, I feel these companies doing these so called "Restorations" forgot a few very necessary words, "Restorations on only what can be seen after assembly." If someone, and most of these companies doing Restorations are one man business’ so it more than likely comes down to one bloke, and if he feels there is no need, or spends hours on the blades of the Propellor but does zero to the ‘mating’ surfaces that matter easily as much as the blades, he is in the wrong business. I seriously doubt whether 10% of these companies have any qualified engineers working there, who seem to choose to do these types of jobs because they almost do not need to get their hands dirty, as in most cases the parts needing work on are removed by the owner, so the Restorer gets, one must guess, the dry and more or less clean prop’ and maybe a shaft, and as I say works on only what he can see, bugger any thoughts of finishing the job properly, no pun intended. I feel it is akin to assembling a car engine but not greasing the bearing before and or as they were fitted, and then telling the car owner it is a wonderful new car and everything is ready for the ten mile journey home, but forgets to mention there is no oil in the engine!. . . Except, will he manage to drive that distance before his engine seizes?

[@KeithFenner]

There are several name brands and some of the company's are still making boxes today and a few still repair their own. George Scherr Co.also H. Gerstner & sons are two of the most popular I've seen. Google machinist wooden tool chest should start you off researching your box and when it was made etc. ;{)------

[@thomasb1492]

i like to think the bore was left that way intentional,like you donot touch the prop or even talk of their pitch ect,,they lert it for the expert,,you do it your way and i can not do it wrong...hand you everything shiny..but if they chip or take off too much.....makes sense..

[@sawdustmaker49]

why was the keyway not spooned?

Show your support for Keith*, Be sure to visit the turnwrightmachineworks . com web site where you can buy Turn Wright Hats, T-shirts and work shirts or leave a tip for Keith. *I am in no way associated with Turn Wright Machine Works or Keith Fenner who I've never met. I'm just an admirer who hopes he'll keep producing these great instructional videos. Maybe some coin from those of us who enjoy his work will keep new videos coming. I bet he'll never run out of neat projects to share.

[@krisdevoecht]

Keith, I notice, sometimes you are small and sometimes you are smaller, maybe my eyes are not so good anymore ...... ;-)

[@brianpanco8325]

look at the hammer marks bad work I will never take my prop to a place that don't take care of all the prop bore and all not just the blades somebody truly got shafted waist of time take it to keith it will be done right

[@aserta]

I'm not an expert or anything but that prop looks like crap. The finishing i mean. I do work with metal so i do understand how you finish metal. Imo that's not finish that's just lightly scraped the old surface off. Maybe there's something about prop refurbishing that i don't understand, but it ain't right in my eyes.
