[@michaelbeary]

I really appreciate a youtuber who fully illustrates how they've failed or made a stupid mistake. It's a refreshing change to see an honest person without the neurotic self absorption that makes people create overly scripted, overly polished perfect "look at me", essentially selfie youtube videos that fall along the spectrum somewhere closer to an oiled up Kim Kardashian with silicone fish lips. All filmed from a selfie stick talking about the newest, most fashionable social cause, i.e. adopt a Somali pirate baby and name him after a popular tropical fruit, or how impatient Donald was by over feeding ornamental Japanese goldfish. Anyway, thanks AvE. That's what I meant to say.

Yup. Probably couldn't as he is likely a citizen of Canada not USA. Reminds me I voted last night... we have these clusterfucks of ballots with "Ranked Voting" which seems a royal PITA. We actually have some NEGATIVE vote value results. Oh, the humanity!

[@bogdanmarkovic]

@AvE I cant but Im pretty sure you can calculate the force on those plastic gears so the whole actuator can withstand 6000N which is around 600kg. All in all, I’m pretty sure those gears don’t need to whitstand a lot of force. And the argument that plastic shroud around those two gears can colaps, it cant because as I saw it sits in a round aluminum tube of the same diameter so no play for that thing. Days of all metal and skookum are over but still there are good stuff, they r just made with economy in mind. If plastic is ok to whitstand 150% maybe even 200% load why bothering machining or sintering metal gears and housing. Swiss r smart, I wouldn’t question it. Btw once again a good video showing some skookum stuf

[@himesjon]

Bogdan Markovic i purchase a lot of stuff swiss made (read $$$$) and they use Acrylic Delrin FR4 Nylon for construction. Some of it is required to be RF transparent. It costs a crap ton. Most things work just fine but every now and then one of those parts fail bc of the engineering not the material, which is usually engineering with that (wrong) material in the first place.

[@Cheradanine]

Yep, all of the above. The beauty of good engineering is understanding the requirements of the job and building something that does that job, with the minimum of parts and cost and that will last the projected lifetime. Sure, you can build it with metal gears, but all that might do is just drive up the cost and weight. Any fule knos that it's easy to build something complicated- the art is building it as simple, as economical and as efficient as possible. In this application, metal gears may be more inefficient in terms of costs.

[@MikeHunt79]

I've been told nylon is self lubricating, so even if they are less strong compared to metal gears they need less or even no maintenance.

[@gabbermaikel]

cheradanine that is why over engineerd means weaks as F. Something that has been over engineerd has been design to just barely stand up to the job it has to do for the amount of time it is intended to do that job. Poorly engineerd means skookum as frig. That stuff is way over build, strong as hell, no failure mode because if you dont know how strong it is and it should be better just make it a bit stronger to be on the safe side. That is probably why us amateur builders tend to build things a bit to strong. No calculations? Wel just put in a bit more then you think you need and its probably 2-3 times stronger then it needs to be.

[@blubblub123123]

Bogdan Markovic if you know the pitch of the trapezium tread and the gear ratio of the sun gear it isn't that hard anymore.

[@doOf3r]

The Swiss use these to punch holes in their cheese.

[@littlegrabbiZZ9PZA]

I have a caveat about the skookumness of the gearing: Yeah, they'll die slowly if they get warm, but it says right on the thing that it's rated for a 1:9 minute duty cycle. Ain't gonna get warm if you use it like that.

[@colinpartridge4015]

Yeah, but if you give the switch to the apprentice - good luck getting him to only play with it for a minute. Unless there is a temperature shut-off in the electric bits - it will get used more. Cheap stuff says "You used it wrong", good stuff doesn't break.

[@gabbermaikel]

first of all cheap stuff dosn't say you used it wRong, it says you used it wong. Now that that is out of the way we all know that the apprentice wont last more then 30second playing with a shaft going up and down...

[@CyberlightFG]

Good stuff only breaks if you don't use it. Stay within the specs.

[@plkracer]

Hey AvE, there is an anti-backdrive mechanism in that support bearing housing. Ball screws have little friction, so the actuator would extend or retract with a little load if the motor isn't holding position. Thomson linear has some pictures of their backdrive mechanism, basically a brake that locks up tight.

[@JesDyr]

and he is attempting to run it without the cap on the back.(seen in the last shot). If he completed the assembly, it would likely work.

[@MrJamesBanana]

In addition to testing those rusted nuts, it would be nice to test which solution is best for keeping the bolts in place. Stuffs like loctite, nordlock wedge locking washers, spring washers and lockwire.

[@felixar90]

IIRC he already said he was going to do exactly that. At least he talked about loctite

[@m1stertim]

[@Larshjort]

I've worked on some equipment designed by some Canuckistanians who didn't understand what salt and water does to steel. Black steel plates connected with f**king countersunk 1/4" allen key bolts with nordlock washers under the nut. Try disassembling that shit while hanging in a wire 60 meters above the north sea after it has been there for 2 years and it suddenly fails to everyones surprise. Oh, and during assembly they really splurged out on lunch and forgot to use grease at all. Those nordlock washer are crazy, if I need something to stay put, that's where I'll put my money. Safetywire comes second.

[@bogdanmarkovic]

James Banana Nordlock...end of story

[@gerettbarker8834]

James Banana lockwire for the win takes time thou

[@SeanBZA]

Have had a Centurion actuator drop a motor, and that motor was so well sealed that only after I had it out and opened it could you smell the crisp. Sealed up pretty well, the only thing was that it would run poorly, and looking after at the cremains I was not surprised. New motor and it was fine again. Now I just keep a service exchange unit, and it is a simple matter to spend 10 minutes doing the swap and then fix the other as spare. Not as nice as that, but for something that lives outdoors and runs 100 times a day getting 2 years out of them is not bad.

[@rsluggy6485]

Quadrature encoding with the 90 degree separated sensors! An attached brain would be able to extract RPM and direction. The two pole magnet and the 90 angle between the sensors would allow you to extract 8 clicks per motor shaft rotation and watching the phase relation between the transitions on both sensors will allow detecting direction. Knowing the total gear train reduction would let one calculate the position of the actuator, presuming there is also a signal available for either limit. Run it to one limit, zero a counter. Each encoder tick is 45 degrees of motor rotation, from which the linear position can be calculated, within the tolerance of ball screw backlash. Love this stuff....

[@thisismyname1920]

I want to say that the nylon gears are likely the most appropriate choice to implement a design-for-failure feature. Considering that its rated load isn't relatively high, if it were to fail, the gears themselves would be the easiest and likely the cheapest to replace rather than the proprietary motor or actuator (not to say the gears aren't proprietary either). Furthermore, it wouldn't be wise to have glass filled nylon on the account that it is soaked in grease and would be susceptible to moisture ingress plus, would also reduce its wear resistance. That being said, I would argue that the nylon gears would be a fine option for this actuators intended purpose. Any thoughts?

[@mickyparuch926]

ok, its good to know im not the only one with a get to er later pile...lol..suggestions? your the tear down guru! no doubt my get to er pile is way bigger than yours...but i do learn alot from you. great vids.

[@GermanToolReviews]

If you want to see some accelerated rusting I would try putting those nuts in bleach overnight. I found this out by accident when doing some experimenting with de-chroming some tools. I don't know the science behind it, but it sure did make those tools rust.

[@scotbogart6551]

Magnum Oxidizer that bleach, NaClO.

[@teknikulrighter8454]

It's the chlorine. Halogens attack iron with a vengeance, producing deep pitting almost immediately. Even just off-gassing from pool bleach tablets in a tool shed can destroy steel tools.

[@marfinhead]

A touch of Ferric Chloride will really speed up the rust. Since it's acidic it will remove any surface contamination and it justs likes to rust with the oxidizer side.

[@heyyou5189]

The old bridge builders of nut and bolt times put the hardware in a bucket of piss.

[@plebwarho4381]

A mix of acetone, alcohol, acetic acid salt and water works well too.

[@wvcollective]

Dude does the final position of shaft matter on Assembly I.e in your pivot end is on the diagonal to the case ? Just a an observation in my head it didn’t look right to ones I fitted on a posh house gates love the vids bro info packed and a inspiration for all peace

[@creativitylapse7487]

Did you put that snap ring spacer back in? If so, maybe things loosened up too much from the disassembly and adding another spacer to tighten it up will do the trick. Are you could just try glueing the gear housing to the drive coupler to keep them together.

[@parkerbender]

It needs pushed together to unlock that transmixer, right? Could maybe putting that clip back in the end and screwing the cap on give it the last little bit of squeeze it needs to unlock its chastity belt, maybe?

[@reedreedreed]

Did you try unplugging it and then plugging it back in?

[@zabzinski]

Dear Uncle B, The best way to get those nuts good and rusty is using a cyclic corrosion test setup. 12-14 days in cyclic corrosion can be equivalent to approx 1 year in a rusty environment. You need to mist (or spray) the parts with a salt water solution, then dry them with a fan or elevated temperature, and repeat. Best of luck! Ps. Would love to see you build a quick and dirty diy cyclic corrosion test chamber!

[@lexeindhoven]

These round "ball like" components are diodes. Probably for the motor sensors. Looking at the unused header and the grey bandwire coming our some sort of hall sensor is a option.. depending which version you buy

[@androidtabsuser348]

You need to watch the ad that was playing beforw this video: the ad was for the automated toiled bowl cleaning brush that spins around the bowl cleaning. Anyway, this might be a fun project to fabricobble on your own at the shop. Plenty room for integration of arduino, motors, solenoids, switches, relays and who knows what other dangerous devices.

[@blly509]

I got semi far in the comments and didn't see it mentioned, but this looks like an office place actuator for moving desk tops up and down. We got a couple at the power plant I work at for that purpose at our operator desks. The signal wires send a height feedback to the controller.

[@vipervette03]

Try to clock the white nylon support with the transmission correctly then reinsert. Just a suggestion.

[@chrisjw1983]

Is it easier to assemble vertically with the arm pointing upwards? Gravity might help hold the drive and gear box together.

[@NickMoore]

Perhaps you could do a video showing the difference between a ball twister and a ball screw. My plant seems to have both but they are used for wildly different applications.

[@ThatEngin3rd]

So that switch running at a lower speed is basically working as a snubber valve to the ball gear as it reaches the end of its travel to slow it down?

[@andrewbielinski1401]

ok my two cents worth the two screws on the side are to hold things in place try sliding one have down line up screw and lock her in place then slide other side in.now the first side won't be pushed to far to where the second side installed won't push the first side out of place. If it works I would love a blonde one rule and a t-shirt.

[@eddie5556]

You didn't try it with the big C clip and end cap installed. Wouldn't that compress the assembly in the housing?

[@gilbreathca]

Bwahahaha! "Not Booze"!!!! Hillarious bottle content label! Safety third!

[@stevenbiars6212]

The extrusion is round inside, so if the nylon enclosure got hot, it would be supported by the aluminum casing, right? The nylon gears could still technically provide a weak point, preventing damage.

[@geobas1]

Not sure but isn't the ring you pulled out first still sitting on the bench? Is that a spacer that keeps the assembly pushed together so out doesn't lock up? Maybe I'm mistaken but I thought it was the first thing you pulled out. Does force on the end (with the cover off) free up the mechanism? Was the silicone acting as a spring and putting the last bit of force on the mech to free it up?

[@ramairgto72]

Hi. Thanks for the brass-shim trick! Magnetic viewing film - awesome, I'm buying that today. Plastic gears? Argh.... Well, something has to break if it jams up entirely. Sure wish it would be a plastic replaceable crush rod, instead of specific gears that are nowhere to be found.

[@akawireguy1197]

Man what a fine gate opener for a 16' gate that would have made. Stout and limiters built in.

[@LukesAmateurHour]

You could try milling out the housing along the length where you're having the innards gum up on you so you can get in there with some "persuaders" to keep it in line and unbound.

[@vincedibona4687]

I like how Delrin becomes "Dellarin" in UB's version of Canadian.

[@Not_Whelan]

Is that the same Jeezeless clip "spacer" from the back end laying off to the left at the end there? Could its missingness have anything to do with not being able to get the thing jammed back together hard enough to chooch?

[@jeremiahblatz]

I think the nylon gear housing isn't structural, it's just there to hold the gears in place while you insert it into the giant aluminum housing. Once inside, it's not deforming without bursting the AL case. (In fact, being thin is a virtue; less compression.)

[@johnfrancisdoe1563]

Jeremiah Blatz That isn't just a nylon housing. It's one of the key mechanical parts of the force transmission in the planet gearing. The teeth on the inside actually need to take the full force of turning the actuator screw.

[@bobsofia68]

Not sure if I missed it but didn't hear what this actuator was used for in it's service days before being rocketed to Hoth. Reminded me of openers I've seen on large iron gates, but they aren't as skookum as that.

[@445supermag]

Since you don't need it to be back exactly to factory specs, bore an access hole so you can assemble it, then plug it (maybe one of those flat threaded plugs they use on electrical boxes).

[@robindonnolly3261]

Is there access to aid the alignment through the screw holes before you replace the screws?

[@atkelar]

Could it be that the "weird spacer arrangement" in the back could have something to do with it not locking up? - excerting foce towards the connection?

[@fluffymonster503]

Hello AvE It looks like you didn't put the spacer thing back in that's probably why when you put it all together it doest get enough compression to force the two half together to keep it from locking up. Well that's my guess at least please let me know if it does work

[@SupremeVerminAirsoft]

If you want to get good rust I recommend using vinegar and salt to break off the top layer and then use some salt water on it after to get a fresh layer of metal to have a good place to get some good rust.

[@TBrady]

Is it a nylon gear housing because the extruded aluminum case holds the shape of the gear set and won't let it crush or warp?

[@phinok.m.628]

Yeah, I was wondering what you mean by there being no hall effect sensors, since there were four thinner wires going into the motor which would be enough for two hall effect sensors (since you need two wires for VCC and GND). Although I guess one would be enough, since that's probably not gonna be moving without power and if you're giving it power you know in which direction it's gonna spin...

[@frankhage1734]

I heard the Jeslus clip (that prevents it from turning at 6:54) snap out of position when the gorilla pulled the drive apart at 4:47. It's obvious the shaft needs rotate freely inside the bearing housing.

FYI the Greek fire balls are also diodes, sinterglass type, probably 3A rating. Yup, they take low melting glass frit, pack it around a poor unsuspecting silicon chip, and smoosh the whole thing together under heat and pressure. All goes well, you get one hell of a robust diode.

[@davidpenson1615]

The nylon gears only have to overcome frictional losses on that sweet sweet thread. So they aren't under too much stress. Being nylon they are going to be alot quieter than powder metal gears just not as wear tolerant. I wouldn't bank on the resembled part locking up as a failure for AVE to reassemble it correctly. It was in the bin for a reason.

[@vrrd-ps8zf]

AvE, ive been trying to find a decent way of creating large quantities of rust so i can make thermite from scratch, so, i have to ask, what are you using to speed up the process of rusting?

[@liammckennie5538]

AVE love the intellectual content. I’m currently in a welding program in the great United States. I was wondering what type of post secondary education you have? This stuff you do really interests me. Keep it up.

[@briancoleman9330]

AvE, if the slimjim isn't sliding in and getting in tight enough to chooch in tight enough on the mechanism, what if you take a long thin piece of sheet metal or aluminum, that would be between the walls and the slimjim so you can get enough pressure to get it to click into place when you slide everything in? That way it could act like a guide and than you can pull the thin piece of metal out before you affix everything back into place? Just a thought.

[@slamdvw]

does the end cap and transmission snap ring compress the motor / jack screw coupling enough to unlock it?

[@nathan2254]

I know this is an old video but I am curious how the strength of the actuator is determined. I know that hydraulic cylinder strength is determined by the amount of pressure and the amount of area its acting on. Its my understanding that there is a motor that creates a magnetic field and then by switching the polarity you can cause the actuator to extend or retract, so is the strength of that determined by the voltage along with the size of the magnet or the strength of the electromagnet? Thanks boss

Are those two stubby screws on the outside of the case the only things supporting the load on the piston?

[@inthefade]

Is it possible this is designed for a specific use where they want silent operation, and that nylon gears were chosen for that purpose?
