Hey everyone- lots of folks asking why the trim panel screws aren’t water leaks. The bottom screws are all blind holes into the frame members, so no leak is possible. The upper holes don’t have to be perfectly water tight. This is an open tank with no pressure that spends its whole life level and upright. The main fill hatch doesn’t even seal. There’s no need for it. Besides with no pressure in this tank, a 0-80 thread is not going to leak appreciably anyway.
One nice thing about the digital angle finder is that when it shows 0.4 degrees, you can press the reset button and your part is now correct ;-)
Or use a bit of shim-stock to correct the erroneous measurement.
also a lot easier than starting to shim the table/bench!
Nice work,,there's a lot of time in that.....
The tender has an identical headlamp to the front is because this was a switcher. They wouldn't bother taking the engine to the turn table constantly to turn it around. So they'd just hook up the cars to the front and run backwards. Since they are gonna be working at night, they'd need a headlamp on the tender for when they were running backwards.
BROVO
Exactly. Without the rear headlamp, they could only move backwards at dead slow speed.
Generally referred to as a "Back Up Light" in the US@@briancox2721
Great job, Quinn. I love the 'added verisimilitude'!
😬
Also 'pedagogical'. An apt description of your videos Quinn
I said it before and it is still true, this is truly a joy to watch. It is so impressive to see a steam engine grow and develop from raw materials to a final product.
I think the back light has a more important task than just to be a spare. The locomotive is a shunter. Thus it goes forward and backward in the rail yard and has to have the same headlight in both directions to work in conditions that require illumination.
I'm now emotionally invested in this build.
Isn’t that the truth. Recall when there was a gap (or so it seemed) after the boiler; remember thinking “oh no, I hope there’s nothing wrong with the pressure test.”
Only now?
That night shift is always counterproductive to the job at hand.
There's something so special about the journey where a build transforms a fantasy into a real object.
Thanks for sharing, it is looking very pretty.
I know this isnt your plan or goal, but I like it in its unpainted state. It has an old-timey charm and warmth to it.
Blondie, You are an inspiring teacher. Like a female version of Mr. Pete.
I wish you were my shop foreman when I worked in a machine shop! Your machining knowledge is FAR superior to my old foreman!!
I've been on night shift for eight years, that intro lit a spark of trauma deep in my brain 😅 I ran a program 6 hours before my shift the other day and spelled my name wrong on the rework tag! I'm talented. Not like the laser keeps a record of every program and every button press, two clicks into the menu...
I still don't understand why the reverse filing works, but it does. I've taken your advice and adopted it as my filing technique. It works wonderfully
I think it is because the contact point of the file where it cuts describes a smooth arc and not a series of flats which it would if you filed the other way. It is how i was taught and used in my brass 00 gauge locomotives (electric mice) and it has always worked for me admittedly usually using needle files
Yes, exactly. It keeps the file tangent to the curve so it can’t make a flat spot.
Thanks!
Hey Quinn, I have been binging on your vids through the past 5 days that I had off of work. Many hours each day. I really appreciate how well you describe the intracasies of machining (and by extent, drafting). I almost always learn from your mistakes. Thanks
Quinn the Tank is a work of art. I always felt you could escape from a Mexican prison. with your filing and hack sawing skills,( you have made it a science. ) but now I feel you could escape from a super max prison !!!!!!
If your printer has a manual feed slot, you can define your own custom paper size, and avoid the whole "registration marks + cutting + taping" exercise.
The most extreme I've printed (on a cheap Brother A4 laser) was about 1m long x 10 cm wide. A label to go inside shopping trolley handles.
I had all sorts of hassles trying to poke in and align bits of paper until I realised I could just print the long ribbon in one go if I told the printer a custom paper size.
Dang Quinn - that looks really nice!
Curling is pretty cool, I gotta admit.

For someone who made a video about tolerances and accuracy, you're acceptance of minor errors makes me feel much better about the mistakes I make with pieces of dead tree carcass.
Those aren't mistakes. Those are uniquenesses.
Well it’s about knowing when accuracy matters and to what degree. Sometimes tenths matter and sometimes they don’t, but precision is expensive (ie. time consuming). Try to never apply it more than you have to (which is easy to say, but precision is also addictive and we all overdo it sometimes).
Wow. That's a heck of an accomplishment.
I agree... it's looking better and better!!! Also I learn a lot watching your videos.
As an old timer, I could not agree more about filling skills. Practise them, find your way to file flat and work out what you can do with each type of file. As an Apprentice 60 years ago, filling was beaten into us until we suffered from tang fatigue. Good filling skills will get you out of trouble more times than you will ever know and will also get you out of prison.
Our nightshift carried the blame for all scrap and rework jobs, funny that 🤔.
Ditto.
First exercise at the Dockyard Apprentice School was to chisel and file a 1” dia. Bar into a square bar.
Then drill, hacksaw and file a try-square.
Then go back and file chamfers, and radii on the square bar…
I guess the first four weeks we’re filing exercises… yep… sixty years ago.
Robert
True. 35 years ago in trade school the 1st 4-5 weeks were spent on nothing but learning about files and filing shapes, surfaces and contours. Learned how to draw file something flat and how to use chalk in lubricating and cleaning files.
Looking great, hello from the UK

Quinn...I was able to find 1-72 flat head brass machine screws pretty readily. The tap drill size is the same as for 1-64. I've had good luck re-tapping holes in brass before or you could drill out the holes larger and repair and redo. Try Walthers Tools for the screws. Or you could use stainless in 1-64 if you're going to paint them. They're easy to find.
I like that reference to the "Roaring Game". I grew up in the Curling Capital of Southern Minnesota, Mapleton.
Your videos are always such an enjoyable addition to the weekends :)
Two thumbs way up 👍👍
Ohhhh, nightshift can be a pesky bunch. Thanks Quinn, helps a lot!
at 23:47, the temp assembly of the tender looks outstanding. love your work.
It looks fantastic despite that darned night shift ! ! I might be guilty of looking at too much steam punk art.... I can't help thinking that with a little patina and a clear coat that the tender in all its coppery and brassy goodness would look great without actual paint. Oh, I know it's destined for paint and that it'll look great.... But I can't help wondering....
I've missed watching your work! Why do I do myself injustice? Don't know what you're making yet. I'm just glad I'm back.
My granddad was one of four guys who scratch-built several 0-4-0 A5a switchers in 1.5” scale in the 60s. Love these little engines!
foreshadowing impressed much intensifies
Enjoying this project immensely Quinn, thank you for bringing us along for the ride, Cheers
I grind old needle files into chisel shapes which I use to remove excess solder.
I can attest, all my corners have been much better since I started using your filing technique. Thanks!
The A3 class had both headlights and backup lights for similar purposes. No, they were never swapped out! Pennsylvania Railroad called itself “the standard railroad of the world” as it built massive numbers of various classes of many locomotives designs, but each built to a specific appearance, including that Belpaire firebox. Yes, there were variations to individual locomotives, as the shop fabricated changes handed down from the main offices and executed by blacksmiths and mechanics. Another type of light you may need to fabricate or purchase and apply with be marker lights on the front and/ or rear of the switcher. By the oddest chance of fate, a single A3 exists today and runs in the summer in Williams Grove, Pennsylvania. You should find good photos on line.
verisimilitude, pedagogical. Thanks for the new words for my 80 year old lexicon! Not sure I'll ever use them in a sentence but impressive just the same.
Thanks Quinn!
Hi Blondihacks, I really like your channel and your work. You’re a great teacher and very skilled. Thank you for doing this channel -I know that this more of a labor of love rather than a means to make money.
we don't have mistakes, only happy accidents - Bob Ross
Thanks Quinn
It looks really good actually.
The old pattern maker I worked with told me that he once worked at a place where, among other things, they made patterns for casting locomotive frames. They put the worst pattern makers on that job because they could be out by a large part of an inch without causing any problems.
😂
That tender is looking fabulous.
Excellent work Quinn, your patience far exceeds mine.
I guess, being a patron, I must've seen a video out of chronological sequence; so, knowing the mistake of the angled light platform was coming, found myself talking to the screen trying to warn you of your upcoming mistake. It didn't work. You still made the mistake! Lol. Being you are in Canada, I'm surprised you used the "Imperial" fist of failure, and not the "Metric." I enjoy your videos immensely. Great work. I can't wait to see the Tender powder coated. Thanks for your videos. I hope use the knowledge I learn here for my own machining. I just have to get "all" the equipment first and retrofit the garage, before I can make my first chips.
I love this fresh steam punk phase the project is going through. It looks super cool
To make a few countersunk screws perhaps you could run a nut down to the head on a round head screw, solder the nut then machine it in the lathe.
The night shift. Always the scapegoat, never the GOAT.
Wow Quinn is really coming along and looking great! Thanks again!
First, I know it will look great once it's painted, but, in my opinion, it looks fantastic right now. I like being able to see where I needed to make repairs/adjustments, but that might be just me. Second: what you said about having to remake something you screw up on taking way less time is absolutely true, and the remade part now has a story to remember. If the part I have to remake is not because I chewed it up but, like here, because I made a mistake in direction or dimension, I try to think of a way to use it in a different project. I've even developed little projects based on 'bad' parts.
Yep…i like the raw, steam punk/mad max look….
Love watching your well narrated videos. Also, your honesty for the minor errors. Thank you.
A trick I learned years ago, regarding printing and the error getting lines on pages to line up: if you’re using a laser printer the rollers will actually slightly stretch the paper as it goes through meaning that the leading edge is slightly narrower than the trailing edge. To compensate, rotate the image on the second page, and align to the correct edge. The orientation will depend on the way the printer feeds the paper.
I love how the rivet pattern highlights the sides. It's really coming together!
Super 77 is really good stuff. I use it to affix printed templates to the board when cutting fret slots in bass/guitar fretboards. With my very basic caveman woodworker neocortex, it's really easy.
Looking great, thanks for posting your work. I really enjoy watching. It's like my little moment of sanity and relaxation.
Another great video, when you put up new content, I always make a cup of coffee, Laen back and put my feet up and relax, thank you for making great content.
I know you are planning on painting the tender, and I understand why. I think your work stands and looks great in its raw form!
Curling for the win. Go Team Homan!
I enjoy almost all of your content(99.5%). Even though I probably will not make any of your projects, as I do not own the tooling to do them, I appreciate the skill it takes to manufacture all the things you make. The technics you show are applicable too other things and that is what I really like about your channel.
Lol. I'm glad to hear you admitting that you enjoy the sound of the tender rolling back and forth on the track. I'm always impressed with your work and channel. It will be depressing to see you paint all that beautiful brass and copper. Enjoy your week and see you next weekend. Lol
Looking great!! Detail parts sound really fun, can't wait for them. Go tender project!
Wow, really looking fantastic Quinn.
Quinn, the light on the rear of the tender is a rearward facing headlight which is illuminated when the locomotive is backing up. I really enjoy watching your videos and I await the next one. Say hi to Sprocket for me.
I can see this object was built with “tender” love and care.
Wow.
Many great tips as usual, and I will take your cautionary advice about fixturing screws to heart
As you may already know modelers can sometimes suffer from rivet counter syndrome and we can find ourselves chasing perfection that didn't necessarily exist in 12 inches to the foot scale.
Going back to 12 inches per foot scale, switch engines worked cars in both directions. Railroad rules require a white light display no matter which direction the engine is working. So when pulling cars in the 'traditional' direction the forward light is correct. But if the next string needs them to nose in to get the string, the light on the tender now acts as a headlight. Of course, as noted, it also makes a good work light when 'lacing up' a string to move it.
I don't know why it took me this long for the thought to occur, but you can sing Pennsylvania A3 Switcher to the exact rhythm, meter and tune of Pennsylvania six-five-thousand.
Great progress again this week. Filing is becoming a lost art.
Great vlog Quinn and its looking mighty good. Here in the UK, (I believe) the engine was fitted with front /rear lights (Red light at rear) on the engine. When coupled to a train the rear light (red) was moved to the very last carriage, this was done so the signalman (in his box) knew when the last carriage had gone through and could safely move signals/lines etc. Just thought i would mention. Stay well.
I can’t be the only one that was thinking “make the noise….” when the digital level hit zero.
In colour!
Beautiful compilation of work Quinn, I salute your talents!
3M Super 77 - the Paste Up artist's best friend.
Fun video, as always!
the Coal Stopper is mainly just there to keep the coal pile from dumping everywhere onto the footplate, because if a stream locomotive stops that hard, you've wrecked it.
oh just noticed -"aaand Yahtzee" plate in the background lol
Robert Pirsig's book "Zen and the Art of Motorcycle Maintenance" talks about ""Gumption Traps" - those moments well all turns to s*** on you.
Quinn handled a Gumption Trap in this video with style and character.
Kudos.
I loved that book!
Great to hear that the book has transcended the generational divide - and gets to be read by non-boomers.
Looking great! Given the fixture screws on the coal stop, your suggestion for soft solder (or no solder!) would be the go. It feels like I'm night shift all day.
Looks amazing.
Your video titles throw me off when I see them in my Notifications. Every time I saw "Die Filer" I thought it would be a video about a German clerical worker. Now I think I'm going to see a coming of age video about a young woman's first love, named "Tank."
Great stuff as always.
That technique for filing a radius I actuall learned from one of my aunts about 20 years ago😊
You need to have a word with your night crew.
Beautiful work Quinn.
The light on the tender serves the exact same purpose as the headlight on the front of the smoke box. It functions as a head light when the locomotive is being operated in reverse.
Gonna need to build a roller-coaster style track around your room!
The coal stopper needs to be silver soldered for strength to stop the tons of coal in the bin, DUH! lol. Nice work, Quinn.
Measure 3x and then mess up, that's par for the course. It's so annoying when I have had to re-do parts on my ships in spite of lots of careful measuring, sometimes I think the Gremlins live in my digital calipers and change the reading while I'm not watching!
Thankyou 👍
If you ever need templates larger than your printer in the future, I've found that office supply stores like Staples have a "blueprint" printing service that is fast (same day) and relatively inexpensive.
Where you wanted those countersunk brass screws to hold the rear lamp bolster, I can't imagine that, with your skillset, turning down some screws out of brass rod would be much of a challenge.
Great video Quinn, the tender is looking awesome. I thought we were going to get a 'make the noise' intro. I've heard the sink cut outs from stone countertops are a good source of larger, less expensive surfaces plates.
Looking great Quinn.
"I couldn't find the correct screws anywhere" psssst,........ you own a machine shop 👍😁
I design automation machines for my sins using solidworks which has a tendency to crash un-expectedly…..when it does it’s always quicker to draw the parts the second time ! Thanks for the videos!
"Tender behind" might be a apropos title for this segment of the build
