Stuffing box? Oh right, the British. lol! I've always heard them referred to as the packing gland here in the states. Always fun to hear the different terms across the world. Interesting to see heads just bolted on - makes a ton of sense for a scale locomotive. A sister railroad of my museum just recently had a piston come loose, and launched the front head off the cylinder. They didn't have studs made with a groove in them, so they damaged the cylinder casting itself. Imagine all the work you're doing on the cylinders for this model, but, with a 20" bore and 24" stroke. Now they've got an expensive, and time consuming braze repair to do. We had to pull the heads off of our big engine to ensure that all of her studs have the relief groove in them; and found that not all of them did. So that's been the big machining project our way recently...
Pointless trivia: in Swedish, a radial shaft seal (lip seal) is often referred to as a stuffing box even to this day ("packbox" in Swedish), even though there is no actual stuffing nor any box involved anymore. But the function is the same as a stuffing box, so the name has stuck around! It confused me when I first encountered it because I couldn't understand why this silly little rubber ring with a spring in it was called a "box".
As an aeronautical engineer I have had to deal with high temp leaks and I will let you in on a little secret. If you use your Loctite 518, and lay a thin silk tread in the area where you need that sure seal, I guarantee it will not leak. Just make sure to cross the ends of the thread where they meet.
Hi, Quinn! My youngest son is getting married today, down in New Orleans! I’ll watch your video after the festivities today, once we’re back at our AirBnB. Have a great weekend, everybody!!
@@christopherleveck6835 Yes, I saw that! Thanks for letting me know! It's very flattering. I'm a big fan of all his stuff. Top Gear of course, but also his model train stuff and other hobbies.
2 facts: 1) I’ve loved Blondiehacks channel for years! 2) I get covid like symptoms seeing “Canadian Pacific” on a PRR switcher! (Lol) interesting trivia: Starting many many years ago, and still present on their boxcars today, CP is spelled “Canadian” on the “L” side and “Canadien” on the “R” side! Ok, I’m leaving…….
Loctite 454! I had hit a steam passage and scrapped the whole thing and started anew. I wish I would have tuned in earlier. Thanks Quinn! Great advice! 😃
Loving this build series. Was wondering if you might consider a video on something like 'Tips and Tricks to Hitting a Dimension'. I have a similar mill to yours with DRO on X and Y but not Z. Peter hailing from Geraldton Western Australia.
Another fabulous video. I used Loctite 518 a few weeks ago to seal the cam housing on a 16 valve diesel engine, which was the manufacturer's recommended sealant.
How do you deal with any marring of the surface where the jack screw lands on the cylinder block's face after jack-screwing apart the two parts? Would that not mess up the sealing surface?
You're supposed to use the threaded jacking screw hole as a guide to drill a small dimple in the flange of the other part. That way any burr or deformation caused by the jacking bolt will be below the sealing surface.
For small boring bores, found single flute carbide mills work really well. And pretty cheap. Designed for aluminium so nice and sharp, same as using usual aluminium inserts on steel.
After years of watching people make marvellous creations on lathes and Mills, at the age of 32, I decided to go back to school and study engineering. Only to discover that there is absolutely no machining involved in the engineering courses. I'm basically just doing maths and physics with a little bit of practical on hydraulic and pneumatic systems. Oh and that I am vastly less intelligent than I thought I was 😂 I'll get a lathe one day.
That's starting to look like a locomotive! A question: I vaguely remember that early on in the build when you were making the boiler, you said that model boilers are made of copper and bronze because if you used brass the steam would eat away at the zinc. But now the cylinders are made of brass, so clearly I'm confused. Did I hallucinate the bit about stream and brass not playing nice together? Or are cylinders different for some reason: lower pressures or temperatures out whatever?
Looking awesome! The studs will definitely add to the "rightness" of the look. I can definitely say that some locomotive parts have jacking screws in them: I've taken the core out of a heat exchanger from a British diesel loco before, and we had to use the jacking screw holes provided to break the seal and withdraw it. A very different kind of locomotive, but still a locomotive...
Lovely work on the cylinder heads, Quinn. I like what you did by soldering in a stud to attach the cylinder cover. That's a great idea! I followed Kozo there, but I like you're idea a lot. Nicely done!
Aluminium is - - - - . Sure, it can be. Maybe it is not available in small quantities, but there is such a thing as "micro chip" aluminium. It machines like brass. Wonderful stuff.
If the flats on the rear covers for mounting the cross head rails need to be very precisely aligned with the cylinders would it be reasonable to have an alignment pin or is that massively overkill? I know it's done on bigger things for alignment when bolts aren't precise enough.
I have faced the problem of not being able to get a micrometer in some tight spot. I have solved it by using a bigger micrometer and some way of offsetting the measured surface. Gauge blocks work perfectly for it or if you can't fit a gauge block in the tight space then a pin of known length will work relatively alright. You just have to remember to subtract the offset from the measured dimension to get the actual dimension of the feature.
Hi Quinn, The head turnings look great. I like to machine brass. FYI I think you could have used the 5/16" pilot point drill bit for the stuffing counterbore as it would already give you a flat bottom to the bore. I've used them frequently to get my bore diameter close with the flat bottom already created.
Maybe I’m being stupid, but couldn’t you make that back-side boss by turning the part and putting it in the collet chuck? Or does that sacrifice concentricity to an unacceptable extent?
I'm not sure if you're aware but they do make micro boring bars with inserts. The smallest I've seen is I think 3/16? I don't think they're too expensive but you do have to use with care, they can snap off if abused.
It would be nice to know how much time was actually spent in machining/studying the blueprints/figuring out how to do the work/work holding. Your videos always makes things look so quick and easy. I'm guessing it took much longer than 23 minutes ;) .... Screw heads not lining up continue to make me twitch.
Because I'm a perfectionist at heart. How would you go about making sure that all of the slots have similar orientations on the cover screws for the valve chest?
One way is to make your own screws with a thicker head, then tighten them all up machine off the top and remachine the slots, a lot of work but you could do it
@@AM-uw3gp you also would need the matching screws to mate in the correct holes. Get them mixed and there goes your frustration level^^. Removing material from the back side of each screw is another way but then the heads are different lengths. So 6 of one... OCD can be tiring.
It can be done by not slotting until after you fit them. Keeping up with what goes where is the answer... tiny marks inside the back of the screwhead might work well enough if you can ensure those marks don't act as raised dimples. Screw wire to mark them comes to mind. They are either in the right hole or in the right harness for that to work. Tedious work can be its own joy, right?
Stuffing box is also nautical as is stern gland. I learnt that from other YT vids. Now I know since steam came before propeller powered vessels, the egg does indeed precede the chicken. ThanX TH-cam.
UGHHHH the beginning of this video is sooo boring... ;) I am living vicariously through you as I can no longer have my lathe set up due to power and landlord restrictions.. I wait somewhat patiently for every Saturday and your videos.
Those cylinders are so good looking. The heck with paint, just polish them to a mirror shire and add a coat of clear. 😊 The sound of the cylinder cover snapping into place was very satisfying! Question: Why did you only add one jack screw hole? Would it not be better to have two for equal pressure? ...or did I miss something?
Wait, is this some AI hack video? It can’t be a normal Blondie video. I saw no chamfering of the any of the bolts. Are we now animals? Still love the video.
One more step toward finishing a very nice series!

hello Hyce the Chanel i was talking is yours
Nice to see you here hyce, you planning on making your own Steam locomotive models?
@@GamingCraftTeam Yes. The 12" to the foot scale kind.
@@Hyce777lmao
You do fine work, Quinn, and good narration as well, it's a pleasure to watch you complete your jobs.
i love the sound of a micrometer ticking in.
i love this site.
I'm enjoying the videos, former shipyard outside machinist here. Packed a few stuffing boxes in my time, 3" rope covered in tallow.
Can't belive it's been nearly two years I've been watching you make this locomotive, great work as always. 👍
I refuse to believe this tidbit of information. No way it’s been that long.
@@ericpaul4575it started one month ago right ?😂
Those look great Quinn, Very nice Job. I really enjoy watching you make things. Your ability at precision Parts is incredible.

It confused me when I first encountered it because I couldn't understand why this silly little rubber ring with a spring in it was called a "box".
And of course, "gasket" is "packning" in Swedish
Stuffing boxes are also used with prop shafts on boats. I think (maybe?) steam locomotives borrowed the term from the sailors. :)

Loctite 545 is magic- it’ll seal anything against steam no problem. I call it Machinist in a Bottle 😀
I'll bet you'll be glad you put jacking screw capability in your application. Much wiser to have it in forethought than afterthought. Well done.
I am in love with this series.
Jacking screws are often found on (front) automotive brake rotors, for the very reasons Quinn mentioned.
9:26 Coulda gone with "Easy peasy, grooving smoothly"😂
Band idea: "Swarfy and the flying chips"
Things are coming together nicely.
YAY!

How do you deal with any marring of the surface where the jack screw lands on the cylinder block's face after jack-screwing apart the two parts? Would that not mess up the sealing surface?
It’s already not sealing in that spot because there’s a hole there

Love seeing your work, thank you!

I’ve thought about it, yah. I think it would be a good idea but also Kozo doesn’t do it so maybe it’s not that necessary.
Brass makes such nice satisfying chips.

DONT fire the writer, we need to see the conclusion to this series 😂
Measuring down in that bore... sometimes you just have to use the close-enuf-ipers. :D
I love your work, Quinn.
Love it doll!❤️🌹
Nicely done again Quinn.👍👍
Gorgeous work.
Quinn,
That rotating V Block looks very intriguing. Besides using it as a stationary V Block what else can it be used for? I think I need one now haha
gorgeous work
Very nice work Quinn. Thank you!
Chefs kiss as always Quinn!
I learn something every video , thank you Quinn
Looking forward to see the pistons and the slide valve made, great job and thank you for sharing.
Imagining two inch slotted screws on a train.
Locite 518 sealer is great stuff. The jacking screw holes are a nice touch. Well done.
At the 14:00 mark what is the name of that fixture?
Great video Quinn
"Easy peasy groovy smoothy" Sure, it's a bad rime, but it might serve.
Yup that’s the one
Another awesome video. Thanks for what you do.
Where did you buy the tangential tool holder?
Very very pretty, nice work!
⭕️ 😮
It's looking good!
All four heads having a six bolt pattern is something that both Kozo and Doctor Frankenstein could use.
And no mention of the heavenly smell of the Loctite 518?? ❤
Maybe I’m being stupid, but couldn’t you make that back-side boss by turning the part and putting it in the collet chuck? Or does that sacrifice concentricity to an unacceptable extent?
My guess is she doesn't have that large a collet. But as a method it would be OK, at least on this project.
Remind me when you're finished to ask what the total build cost of this locomotive is 😅
Thanks Quinn
Don’t worry about being fired it will get better
I’ve fired myself so many times I’ve run out or fingers & toes a long time ago
Thanks Quinn, helps a lot!!
Yay!! It's Blondihacks time!!!
