TENDER IS FINISHED! - Pennsylvania A3 Switcher, Part 34

[@jimsvideos7201]

This week's lesson from Sprocket: Do what the Food Source™️ wants, but not in any hurry and only after a big stretch.

[@Gersberms]

Congrats, Quinn! That's a nice looking tender. Anything worthy of the vague disinterest of Sprocket is deserving of high praise.

[@StefanGotteswinter]

Lovely! I feel like you are speedrunning the locomotive. Dont people usualy take their entire retirement to build it?

[@Blondihacks]

Hey Stefan! I am definitely going faster than most, but I have more time to devote than most. It’s also a pretty small and easy one as locomotives go 😄

[@JasperJanssen]

1020 hours - doing the math, that is just over half a year worth of full time employment. That’s a hell of a lot of work, no matter how many months it’s spread over.

[@NicholasMarshall]

Thanks Sprocket for you hard work inspecting Quinn's work.

[@Skyliner_369]

about the seal that kozo designed on the top of the pump, They're basically crush seals. they're amazing at holding all the pressure... the FIRST time, but subsequent times, the surfaces work harden, and stop conforming to each other. the only thing you can do is remake the seal or goop it

[@johnlinquist2998]

Congratulations on finishing the tender. Sprocket's approval is a signal mark of honour. You should be able to handle the locomotive with Sprocket's continued disinterest.

[@jimwolsiffer4397]

Great work Quinn, on loco operations we mostly work as close to the safety limit as possible. If you wait till your boiler is down to what you mentioned you may find your not going to get the effect you need. Your preasure will drop significantly when you add cold water. For my loco I add water when possible while preasure is near maximum. Now I have a more important reason for this I'm addition to yours as my loco relies on injectors and/ or a steam operated water pump. However in your case to maintain performance you would want to add water when preasure is near max operating to reduce as much as possible the unavoidable preasure reduction while doing so.

[@bobdenver3174]

Awesome job. Something you might want to consider if you ever need to seal the inside of a tank again. In the experimental aircraft world they have a liquid that they swish around inside the gas tanks. It dries to a rubberized finish. Works extremely well. Also, if you’re looking for something better than bathroom silicone. A product by Permatex I think, it’s called The Right Stuff(seriously). Used when building engines or sealing differential covers. Works way better than the RTV silicone we used to use. 😁😁

[@johnduerksen9191]

I was also going to recommend a fuel tank sealer. Works great on old motorcycle and lawnmower fuel tanks if you want to squeeze a few more seasons out of them. Not sure if it would work in this application though, because you don’t want to coat the pump mechanism and other fittings inside the tank.

[@mikefrachel8292]

I think I would have made a fitting to put a light vacuum on the tank to draw the silicone into the leaky spot.

[@ryanledoux9982]

Congratulations on a beautiful tender! I can’t wait to follow the engine build!

[@kevinkohler2750]

The "imperfections" are how you know it was made by a live human being! It looks *great!*

[@peterc2248]

I'm not a model engineer, I just find it fascinating and fantastically well presented. Congratulations and many thanks.

[@HeidiLandRover]

Not just a fist-pump, but a WHITWORTH fist-pump. That's really something...

[@0xFEEDC0DE]

DOUBLE Whitworth, DBSW, which is formally an ISO standard, but you have to pay to see it.

[@vrdrew63]

"Love me tender, love me sweet... never let me go.." Just a little bit o' Elvis love to say many thanks for your incredible work on this project. So, so satisfying and enjoyable on so many levels.

[@johnmolnar2957]

Beautiful !

[@Hyce777]

I don't trust small tapered pipe threads either. I only trust the stuff I can put 1000 ft-lbs on and not worry about... lol!

[@Preso58]

Nicely done, Quinn. The black livery looks serious!

[@Blondihacks]

Thanks Preso! ☺️

[@jeromemiller3091]

Congratulations !!!I. I can't even imagine the total number of hours you must have in this tender from the behind the scenes work, the editing, etc. Thanks for a fantastic build! You are an outstanding instructor/teacher! Keep up the good work and looking forward to the engine build!!

[@leeklemetti1887]

KUDO'S Quinn! You have amazed us all. A triumph of construction. Now on to the next challenge. We are waiting.

[@johnapel2856]

Yay! A Whitworth fist pump of victory AND vague disinterest! SUCCESS! Thanks, and Meow to Sprocket.

[@avoirdupois1]

That's a beautiful machine. An amazing journey, meticulously documented.

[@vicmiller7191]

Just wow, girl. Your next hurdle will be just as fun and a great build. I have no doubts about that. And as far as Sprockets opinion, i think Sprocket is waiting to judge the whole project when completed...LOL. Cats are funny like that. What a great build. Thanks for sharing.

[@mtm101designs9]

Really beautiful work. A major milestone after over 1000 hours. Thanks for letting us in on the fun.

[@TheZombieSaints]

😂...Sprocket. At least he gave the tender a good "scale" shot 😉 But seriously, gratz on finishing the tender. It's coming together sweet. Also, I didn't realise it's been over 1k hours so far! Awesome stuff! 👏👏👏

[@ElectricalInsanity]

Congrats on completing this part of the project! It's looking fantastic!

[@bernieshort6311]

You have done a marvellous job making this Tender Quinn. Ok so there were a few difficulties along the way and that is a part of the learning curve. You have every right to be chuffed with yourself. If it passes a CAT scan, then there can be no better confirmation of a job well done - and so say I.

[@brianhaygood183]

Appreciative post expressing encouragement and congratulations while providing the algorithm's required engagement.

[@rhavrane]

Bonjour Quinn, You are too modest and you have just taken a great step forward. I wish I already had a tenth of your skills. Looking forward to the front part 😉 Amicalement, Raphaël

[@samcoote9653]

Ive only read the title so far but I already know this video will be an absolute win! Great Job Quinn!!!!

[@samcoote9653]

Well, that was awesome!

[@darrinswanson]

Thanks!

[@Roblecop]

Truly a milestone in this project! Following this project from the very beginning, today was that much more satisfying. Amazing work, Quinn!

[@garyreisdorf1363]

Quinn, Well Done!

[@rexmyers991]

The tender build is the perfect primer for the loco build. Plus - all the newly acquired skills can be applied to the loco. CONGRATULATIONS!

[@Skenay]

You do amaze me each and every time you show off your work on this platform.

[@johnhagan7645]

That's beautiful, so is the cat. Job well done something to very proud of.

[@ChrisHiblerPinball]

Really cool looking. I’m anxious for the locomotive episodes.

[@jameshodgson1609]

Well done on the tender looks and is amazing. You were absolutely correct to test the hand pump to a greater than the max. boiler pressure. As you can imagine scenarios in service where you might have a white hot fire and you find yourself with an unplanned stop on a down hill grade with the water disappearing out of the button nut of the gauge and the safety valve ramping its head off. You’ll be so happy that pump works !

[@paulthomas3782]

Fantastic effort Quinn, your tender looks fantastic.

[@halo6six6]

I love that you show the problems, your troubleshooting process, and the final resting! Thanks again, Quinn, far an awesome video!! I found your channel right at the start of this project, and these updates are the highlight of my day at work. I’m proud to see my name at the end of your videos and can’t wait for you to share the rest of this build! Congrats on finishing the Tender!

[@ianloughney9570]

You know, I never did doubt you, but my god that is a beautiful machine. It really really came together well.

[@andrewdolinskiatcarpathian]

One word …….. brilliant! 👏👏👍😀

[@Jeff-KN6UDG]

Congratulations!!!! I’m gathering the materials to start this build. Can’t wait to get started.

[@kyfho47]

Nothing to add that hasn't already been said by all. BEAUTIFUL!

[@KeefyKat]

Go Go Casey! Full steam ahead!

[@james1214]

Another killer episode Quinn! Congrats on hitting this milestone. As a kid I always was fascinated with live steam modeling, but have only ever had electric trains. Maybe it'll be something I dabble with as the 40s roll along. My 6 1/2 year old daughter loves watching with me and always yells "sprocket, sprocket, SPROOOOOCET!!!!" When she sees her, she has a love of mechanical things and I am so tremendously thankful for your channel and you, having a female who she can look up to and is into similar nerdy stuff as her dad is so awesome.

[@rickfazzini22]

I’m so proud for you!! Can’t wait to see you build the engine!!!!!

[@CowboyGarage]

Tender looks amazing Quinn! FWIW, I can't say for certain based on your video, but it's quite possible that you are running your NPT taps too deep causing the issues with the tapered threads. We use tapered pipe threads at work and have went as high as 15,000 without leaks. I'm not criticizing nor disparaging your work in any way, just offering one thing for you to look into that may help your disdain for NPT connections. Keep up the good work!

[@andybogart2503]

Well done! I watch you every Saturday while I grill up dinner for my wife and daughter. Wouldn’t be Saturday without you :)

[@RobertBrown-lf8yq]

Wow ‼️ What a Trojan build eh 👏👏. One thing I did notice though. In the early part of the pump testing, the pump was on the floor pan. I noticed the floor pan ‘flexing’ during the pumping action. You may have to somehow ‘reinforce’ the floor plate of the tank? Repeated ‘flexing’ of the brass will work harden it, and you may develop cracking in that area. Great project, and I can’t wait to see the loco construction phase. Regards Robert

[@Blondihacks]

That’s because it wasn’t attached

[@Ioughtaknowbetter]

This is really brilliantly done I feel you on the tubing issue I have struggled with getting correct flex lines for many applications cannot wait to see the locomotive take shape

[@bradjohnson6919]

WOW, that came out great. Hard to believe that was bar stock and sheet metal.

[@markneedham4606]

Purrfect. Good to see a "Dooer " achieve stuff.😊 Me I'm a tyre kicker, and am envious.😮

[@tjolle62]

Supernice project Quinn and it's always a pure joy for me to see a skilled machinist at work . Best wishes from sweden .

[@manythingslefttobuild]

Congratulations Quinn!

[@jameskilpatrick7790]

That's a huge amount of work, but the results really justify it. That's a beautiful tender. I'm looking forward to seeing work resume on the locomotive. Congratulations!

[@patwicker1358]

Beautiful! Must feel good to finish that journey. Can't wait to see the next section done.

[@joscornelissen5626]

You could use motorcycle tank sealer to seal the tender. It's a polymer that creeps into every little nook

[@yowie0889]

"It's not a motorcycle baby, it's a chopper."

[@Kurt-tq6ew]

Well that looks the absolute bee’s knee’s! Excellent work 👌🏻

[@bobflores]

A great accomplishment and a whole lot of hours. Now get to work on the missing part. Thanks for the episode.

[@richardspees841]

Thanks a lot for sharing this journey. The tender looks incredible. Can't wait for the loco.

[@Bob_Jones_]

looks great!.. looking forward to the engine build.

[@raystevens1458]

You have done a FANTASTIC JOB ! This project has me glued to it and looking forward to the next part.

[@cameronwebster6866]

you can make a quick and dirty roll crimp to attach a hose to a barb by replacing the blade in a rolling-blade pipe cutter with something not sharp, such as a washer or two, then you find a piece of copper pipe that just fits over the hose connection you want to crimp, anneal the copper, put everything together, and form the crimp in a manner similar to cutting the pipe, just be careful not to use too much pressure on the pipe cutter or uo will crush the annealled pipe.

[@steveman1982]

Congratulations on this s major milestone, complete with Sprocket's approval!

[@Frostfly]

It's Freaking Adorable Quinn, what lovely work.

[@OutbackCatgirl]

WOOHOO! Feels great huh? Sprocket out here earning that sweet sweet paycheck, as always.

[@andrewdashgdotcom]

Beautiful job Quin - thank you for showing us your amazing skill and the outcome of so much time and effort. 😊

[@ulpilotrmh]

Excellent! On to the engine.

[@PioneerRifleCompany]

Very nice. Lots of work coming together.

[@vandyFixer]

Anti Chafing measures are always worth the effort. 😊 Well done Quinn. looking forward to the rest of the project.

[@tastiger91]

You do magical work.

[@lkw6640]

You need to use thread sealant, either pipe dope or Teflon tape, even on tapered pipe threads like NPT. You have a small chance of brass to brass fittings sealing but why take the chance. I know there’s no way for you to verify this but I fit pipe for nearly 30 years. I know what I’m talking about. We always used thread sealant on all pipe thread. I prefer teflon tape myself but if you want to keep it more authentic, then use pipe dope. Anyway, awesome video! I always look forward to seeing your videos.

[@jeffh8803]

I was about to comment the same thing. The shape and loose tolerances of tapered pipe threads are absolutely not designed to seal by themselves. Teflon tape is the easiest but liquid sealants like locktite work too.

[@lkw6640]

@@jeffh8803 A great benefit of tapered pipe thread is that the tolerances don’t have to be nearly as tight as straight threads do in order to seal well. But thread sealant must be used to ensure a good seal. Another benefit of tapered threads is that the more you thread them together the tighter the seal. You can’t do that with straight threads.

[@boutellejb]

Agree - by design, npt requires sealant. There is another version - NPTF (I think "F" stands for "Fussy", or maybe "Finicky") - that is designed to seal w/o anything added. But they are really a pain to deal with! (not to be confused with "F" for "female" designation)

[@lkw6640]

@@boutellejb that’s correct. The F stands for Fuel. The crests of the threads are taller and actually deform as they are assembled to match each other’s shape nearly perfectly. I’ve never had the need to use them myself but my understanding is that they can only be used in the same fitting that they were tightened into first. They are then forever matched to each other just like unions are. Straight threads are called NTS and require an o-ring or gasket to seal. By the way, I remembered another advantage of NPT. They can be turned to match an angle, like when you’re using a 90 or 45 ell, and still seal. There is some leeway for about 1 rotation. Again that’s something you can’t do with straight threads. I don’t know if she actually reads these posts given the amount of posts she would have to go through, but I really hope she does because she would save herself SO much trouble.

[@Kim-kl5jh]

Magnificent job, Quinn! You completed the tender in record time - it took me about 2 years to complete the tender. You're going to lap me soon 😊 Can't wait to see you start the locomotive. That's got a LOT of fun things to build. You're going to have a blast! Way to go, Quinn!

[@Blondihacks]

Well I have a fair amount of time to devote to it and I won’t claim the quality is as high as it could be. 😄 Your build log inspired it so it’s like we’re building it together.

[@Kim-kl5jh]

@@Blondihacks Thanks Quinn! I appreciate the company! 😀It's fun having you build along with me and seeing your fresh perspective on how you do things. Your updates are always encouraging and educational. Keep em' coming! (You and Sprocket, of course! )😺

[@raymondhorvatin1050]

Congrats on the completion looks very nice

Nice job. I enjoy watching you work. I get to see the machines and not have to pick up the chips.

[@Jim-fe2xz]

"Faced off the end of the stock as is tradition". There helped ya LOL (Sorry just had to do it LOL). I wonder if you could pull a slight vacuum on the tank to pull in come "crazy glue" to fix the leaks (if it didn't wick in on it's own). Cats internalize their emotions. I'm sure she is as happy with the Tender as you are LOL! BTW the world thanks you for inventing braded wire reinforced rubber tubing! Just think of the possibilities! Congratulations on this very impressive project. Can't wait for the locomotive! Thank you for sharing!😏

[@davidchang-yen1256]

I am sure someone has commented already, but tapered pipe threads have a natural leak path through them (I believe fellow Canadian AvE did a video about them), so they will always use sealant/tape. The one exception if I remember is NPTF fittings, and they are designed to deform to fill the leak, and are thus non-reusable (and annoying).

[@davidchang-yen1256]

@@millwrightrick1 the thread distortion trick is certainly what NPTF (the F is for fuel, also known as DrySeal) uses, but as I understand it standard NPT tapered threads are not designed to reach all the way to the bottom of the thread valley even when full tightened, resulting in spiral leak path. Sealants fill this tiny gap, but it does mean a) they will leak without it, and b) you can reuse them with fresh sealant.
