Stuart D10 - Vertical Twin Cylinder Steam Engine - Lets Begin !!

[@steveallarton98]

Hi Joe, Delighted to see you taking on a Stuart engine ! Just one word to the wise : The drawings were produced in a time when things were “fitted” together, before the advent of tolerances, necessitated by the largely American influences of mass production . . . . Dimensions were given in fractions, with guidance been given in words, for example 23/32” bare would be a few thousands undersize and 23/32” full would be a few thousands oversize. The quality of fit would largely be left to the judgement of the machinist. If I were starting to construct one of these models, I would create a general arrangement drawing from all of the dimensioned parts, and see how well they all fit together . . . . “An hour in the drawing office is worth a week in the shop”, as my old boss would have said . . . . Over 50+ years of reading the Model Engineer, there have been more than a few wailings and gnashings of teeth in those pages, on the subject of Stuart’s dimensional inaccuracies . . . . However, I have every confidence in your intuitive expertise to “get things right” Good luck on your journey ! Steve A

[@raistnox]

Anyone else want to see him set up a overhead pulley shaft for this to power his miniature machines?

[@drevil4454]

Yesssss!!!

[@nutgone100]

Absolutely!

[@bryanlatimer-davies1222]

Sure do and build a dynamo to light the machine shop he will build to house them in OK I stopped taking the medication 😂

[@alanclarke4646]

I think we all do! 😁😁

[@v8Mercury]

Ha ha! That was my first thought when I saw the video thumbnail. 😊

[@StuartsShed]

Fantastic - what a generous gift. Stuart Models started in 1898, so the approach to model engine plans hearks back to days when paper was super expensive so they (Stuart Models) crammed as much information onto one sheet as they could, and that practice continues today in the model engineering world. Makes for a bit of an adventure interpreting the plans sometimes - and it's down to the model engineer to figure out the tolerances and fits! I'm very pleased to see this kick off and will be avidly following. Cheers!

[@paultrgnp]

I reckon I'd start by making a CAD drawing of all the moving parts to calculate appropriate shaft, bearing and cylinder (etc) diameters, tolerances etc. PPPPPPP! 😅

[@StuartsShed]

Indeed - that’s a solid approach and rewarding in its own right. 👍 I usually just look at the assembly and work out what is doing what and apply tolerances as appropriate. These days I am very much into training engineers in GD and T so I try to think about it in those terms.

[@Vilhund]

I learnt in school (around 2010) that good drawings should give all the information needed with the least amount of views, in order to avoid clutter and useless complications. And I think that drawing parts that goes together as one in sub-assemblies will give a quick and clear idea of how they will relate to each other

[@StuartsShed]

That's the difference between model engineering plans and manufacturing drawings. That aspect of multiple parts in one part of the plans does indeed help the plans describe intent for the parts in the assembly. In the manufacturing world we require all information needed to define the part, including tolerances, finish, material, size and shape to be on the piece part drawing (per ASME Y14.5 or BS8888) - so that there is no need for interpretation. There are a great many very successful model engineers who never even see the inside of a manufacturing facility - so two different worlds with a bit of an overlap.

[@rallymax2]

And the next binge worthy build series begins!

[@Preso58]

This will be an interesting build and it will provide an impressive amount of power when completed. I built the Stuart Marine Twin which is very similar and it really does sound glorious running loaded and on steam. The BA thread system is a curious one. It follows a geometric progression with each size downwards being 9/10ths the next size upwards. It does scale really well which is why it is used for model engines. It is still possible to buy hex headed bolts and nuts in BA sizes. The castings that support the cylinders are called "trunk guides" but they are also the structural connection between the cylinders and the base frame for the engine. Regards, Mark

[@mrc1539]

And another adventure begins 👍 !

[@glencrandall7051]

Mr Steve Bright is a most generous gentleman. This is a wonderful gift. I am certain that you will do justice by it, during it's fabrication and construction. Please do not presume what is boring to me. I am most interested all aspects of your projects. Your filing technique and the tools used are just as interesting. Some of the filing on that fly wheel in real time would have been most appreciated. Your work can only be boring if you do repetitive operations more than three times. For instance if you have to bore ten holes. After the first three I think most of us get the idea. Show the first two or three and mention you did the same on the remainder. I am a woodworker and I turn bowls on a lathe. As such all your work is fascinating to me. Not ever boring. Thank you for sharing. Have a great day and stay safe.🙂🙂

[@paulcooper2897]

This is a build I am seriously looking forward to!!!

[@vandalsgarage]

I'll have to enjoy this build vicariously, my accountant has me on a strict budget. The basic kit is not too pricey, at about 310 usd, but add the reverse gears and finish pipework, and it's over $550, and then there's paint and so on. That's a generous gift, indeed. And it's a gift to the entire community, as we get the benefit of Joe's instruction, which I can currently afford...

[@joepie221]

This was a very generous and totally unexpected gift.

[@TheUncleRuckus]

Hand work isn't boring, it's content and we're happy to get it no matter what it is. 👍👍

[@MHolt3573]

Thank you Joe Pie for taking the time to make these kits for us. You are a true master at your craft sir.

[@georgehollowell9295]

Many thanks to Steve Bright for sending you the kits. I'm really looking forward to the build. Another opportunity to watch, learn and enjoy you build something. I'm glad that Steve send this model as it will challenge you on a more complex engine, while not taking anything away from the PMR build. Maybe some of you viewers will help you get a proper boiler to run the steam engines. What ever boiler will have to meet the Texas code for boilers, but I'm sure your viewers will come through for you.

[@mikepelelo5657]

I would call those a-shaped castings stanchions. That's my story anyway... Thanks for the video Joe; looks like another very interesting project.

[@Gauge1LiveSteam]

You are going to love this project. #10 is a great design. All Stuart kits are fabulous to work.

[@jmhannnon]

My D10 partially machined kit has been sitting on the shelf for around 40 years. I may be inspired to follow along to finish it. I see they have made a few changes in the kit since I got mine.

[@barrycaudle9926]

A couple of people have commented on the thread angle of BA threads it is 47.5 degrees.

[@db799]

I like seeing how to do things right. And then there is how I do them, but I'm learning and enjoying it. Always amazed by Joe's enthusiasm and positive attitude.

[@jonsworkshop]

Hi Joe, looking forward to seeing this progress. I would be surprised if there is any metric on a Stuart drawing. Imperial fractional dimensions with BA (British Association) hardware is normally how they go. BA were mainly used for instrumentation and electrical fittings and dates back to the 1800's. Cheers, Jon

[@ItsMrAssholeToYou]

I think Joe was confusing metric with decimal inches (0.000"), which _was_ present on the drawing.

[@evr4921]

I am so excited for this build. I have a completed factory machined D10 and attempted to fit it with the reversing gear. I can’t wait til you get to the reversing gear to see how it’s done. I’ll still enjoy the build of the engine because I want to build the V10. Supposedly you can build the V10 with only a lathe, maybe the D10 as well. Are you up to the challenge?

[@guywren4801]

Looking forward to this one Joe

[@Radiotexas]

Nothing better than a steam engine kit build!

[@warrenjones744]

Stuart Models are great. Castings were good back in the day. This should be fun. The one I built was all BA threads back in the early 80's. the one I built was a single horizontal 10 I think. I want to build that one you have and add a reverse gear. Someday maybe!

[@brucetuckey7909]

Looks like another great project for the master model maker.

[@timothypowell5687]

I can only imagine when it's done , Joe. As with everything else you make, it will look absolutely beautiful. Very nice gift!

[@shadetreemechanicracing22]

I will be following this series closely, as I want to make a large-scale model for a boat project.

[@josephcitizen4195]

I've been making drawings for machining and fabrication for 32 years. I can't make heads or tails of that 2.6.15 drawing section. That's three parts? holy cow. Good luck on this one Joe. lol

[@scottjones7279]

I am hooked on these models and your skill of assembling them

[@Bob_Jones_]

cool.. a new project.. looking forward to watching

[@pirminkogleck4056]

awesome! thisnone was realy missing in your videos ! thanks to mr. Bright!

[@onlooker251]

Great to see you, Joe, start another project. 👍 John 🇬🇧

[@russellmcclenning9607]

Thank you Joe can’t wait to follow along on this journey

[@belair_boy6035]

G'day from Australia, Looking forward to following along with this build series.

[@Pest789]

I can't wait to see how you set these parts up to finish them. I always learn a lot when you machine castings.

[@johnmcclain3887]

When I was building a "tiny power Ajax" steam engine, I bought an MLA die filer kit and it does a masterful job for all that flash and cleaning up raw castings. I've had that filer for close to twenty years and pull it out for any casting or substantial filing job. One of the best most useful tools I've ever made. I still enjoy watching others build steam engines, and sometimes find myself buying another kit out of envy! Always interesting to watch you work, Joe.

[@stevenaegele5228]

Stuart models are about all I build. Enjoy!

[@mattomon1045]

I do love steam engines!!!!!

[@sfeddie1]

I have watched Keith Appleton build and repair these D10s and many other steam engines, on his KZbin channel for a long time. Once built there are a few tricky valve timing adjustments to do to get it running smoothly, but it shouldn't be anything you can't handle. I think you should have a fun time building this Stewart D10.

[@bwyseymail]

Yeah, Keith times his engines by ear. But being a musician he has that ability.

[@TomokosEnterprize]

It really is a nice set of quality parts. This will be a fun build for sure eh.

[@jackpledger8118]

Every time I see Keith machine parts I cringe...using wooden blocks for parallels, going to the belt grinder instead of the milling machine. Will be nice to see Joe machine the parts for this engine properly.

[@sfeddie1]

@@jackpledger8118 Keith always tells us he is not an engineer(machinist), but he seems to to do okay. Maybe a little ham-fisted, but he gets it done. He also knows the ins and outs of all of these model steam engines.

[@chrisstephens6673]

​@@sfeddie1 he keeps telling people he is showing the wrong way, like when he silver solders and uses too much to show how not to do something but sometimes I wonder if he knows how to do things in a proficient manner. His use of a micrometer is a constant source of amusement to even the newblest of newbies. He does produce the goods though, by hook or by crook, so one should criticise too much.

[@CreaseysWorkshop]

I have the single cylinder version. It is a stunningly beautiful model with the full reversing gear fitted. I believe the part with the two legs is called the "Standard". The brass parts are now cnc machined but were originally stamped in the older kits. I've got the original drawings and they are very different. I'll see if I can email you a photo. This will be another great series.

[@123Shel12]

OoooooWeeeee! This is going to be GREAT!!!!! Love watching you do your magic!!!!!! Can’t wait to see this project come together!

[@metalmill52]

Can’t wait to see you build this, Joe! Very kind of Mr. Bright to provide you that set of castings and materials!

[@jackbonanno8186]

Beautiful sweat job on the piping and great finishing work. You received a very nice gift to start this project. But having watched you for some time now, I know you will take it to the next level and above. You are not just a machinist but actually a genius in the shop. Love watching your talent and learning from it. Thank you Joe for sharing all your knowledge with us. Have a blessed day.

[@airdrop1670]

Years ago I was shown plans from England and they love to use fraction , they do amazing work on their models for sure .

[@petestephens]

I shall watch with interest. I am a complete novice and have a set of castings for a Stuart No. 9 engine. So far I have been afraid to start!

[@angelramos-2005]

That is a very interesting project and thanks for the generosity of Mr. Steve Bright

[@Stefan_Boerjesson]

Good luck Joe. No doubt You'll make it a beautiful model. Looking forward to lots of interesting clamping, milling and turning. Restoring parts on a 1957 rail car and steam parts on a 1917 locomotive is more my call these days...

[@cmguitar50]

Just came back from Ireland with a 10V, 10H, and oscillator kits, and eager to watch this series!

[@joepie221]

I hope it helps guide your thoughts.

Maybe this will push you over the edge.

[@andrewnaylor3965]

Going to be wonderful seeing this built by you, Its quite large in comparison to the miniature machine tools you have made previously, your detail workmanship is out standing no guessing or using your trained eye just pure accuracy. Thank you Mr Steve Bright for this wonderful gift you have given too Joe for us all to enjoy.

[@TrPrecisionMachining]

good proyect joe

[@roberthiggins1142]

Another great build on the way, it will be great to see some of the holding & fixturing you use on this project.

Watch those steam chest covers Joe... they were well chilled on the S50 I built. Looking forward to this one!

[@leemarsh3569]

Looking forward to this build!

[@joerogi8401]

Woo hoo ! Great start Joe, ready for the next one. John 🇨🇦

[@thomasnewton9818]

Definitely something I'm going to follow the construction of.

[@chrisstephens6673]

If you should find oddities in the plans or parts that you might think an American would not put up with remember these sorts of kits are mostly built by brits of a certain age with a more "make do and mend" attitude lift over from the '40s and '50s. Not saying a kit should be Inferior, just a slight difference of attitude. Looking forward to this series and your perfectionism, something we should all aim for.

[@michaelryan6884]

Nice file work, Joe. Anticipating an enjoyable viewing experience with this project!

[@rods87175]

And another adventure begins! I look forward to watching this series.

[@Gamerock82]

Beautiful kit. Can't wait to see it develop. And possibly be the power drive for all the others. Mini steam shop, here we come. :D

[@ferrumignis]

That would be an awesome setup!

[@BensWorkshop]

The use of BA fixings is because whilst electrical in origin, they look right at these scales where the original would have been Whitworth. Good work, looking forward to the series.

[@tonywilson4713]

As an Australian who went to college in America I can tell you metric confuses all Americans. Its the French spelling and division by 10 that gets them. Go and watch Jim Gaffigan on what metric means to Americans.

[@RobB_VK6ES]

It was the standard for British loco drawings to use 1st angle projection.

[@Khitiara_]

that looks like a stevenson valve gear, cool stuff

[@bertbergers9171]

Looking forward to the series!!

[@devmeistersuperprecision4155]

Oh hell to the yah!!!!!! Not only is this a Stuart engine model but it’s done by “The Pie”!!! This is going to be good. BYW: mixed measurements are nothing new. Just redid my Cummins dodge clutch. Some of its metric and some of it is imperial. Just need to be aware and consistent. Any whitworth threads in this beastie? Did I mention that this is going to be good!

[@markrainford1219]

Yes! The 1/4" X 32 is ME (model engineer) which is a Whitworth thread form. The other I saw was BA (British Association). No metric though.

[@paul.newland]

Watching this series with great interest Joe, I *started* machining a D10 about a year ago which I need to finish at some point... Looking forward to seeing your unique take on some of the challenges! 🇬🇧

[@Michigan_Tactical]

I always enjoy your videos. I'm always learning something.

[@Jeff-KN6UDG]

Joe, you are a lucky man. I just purchased this setup and you’re looking at right around $700 US not including the price of the taps and dies. You do a fantastic job with your videos. Thanks for your dedication.

[@joepie221]

It was a nice gift. I enjoyed the build. Good luck with yours. I hope my series helps you.

[@theafro]

Stuart make lovely kits, and the castings are usually fantastic. Occasionally you'll get a "chilled" spot in them that's super hard, but usually it's not an issue. You're really going to need a boiler before long! sure, you could just use air but there's no romance in it!

[@ElliotNesterman]

FWIW, a file with a tear drop section is called a pippin file.

[@voodoochild1954]

Looking forward to this build series, especially that reverse mechanism. Good Luck Joe!

Interesting that some parts are supplied finished, those tapered round files are commonly known in the UK as "rat tails" Looking forward to the build Joe, thanks.

[@oregonexpat]

I always call them that as well.

[@gagasmancave8859]

Fantastic gift im looking forward to thus build

[@nlo114]

I have a selection of constant diameter chain-saw files for doing radii such as the flywheel spoke roots and rim areas. Keeps them all the same, and easier to balance. I'm really looking forward to this one!

[@MatthewTinker-au-pont-blanc]

Although the BA thread is based on the metric system, it's not a standard metric thread, it uses a 47.5° degree thread with rounded crests and valleys, you won't find taps and dies as metric! Cheers, Matthew

[@devmeistersuperprecision4155]

Would this still be a whitworth? Whitworth are theoretically 50 degrees.

[@MatthewTinker-au-pont-blanc]

@@devmeistersuperprecision4155 No, it's not Whitworth which is 55°, it's 47,5°, it's a thread that was frequently used by mode Engineers. Regards, Matthew

[@JaenEngineering]

It's also worth noting that the sizes are geometrically related. So a BA2 is twice the CSA as a BA1, and a BA3 is twice the CSA of a BA2 and so on. So if you need something twice as strong, you just go up a size, rather than trying to do a load of math to figure out how much bigger the diameter.

[@geoffrose4608]

I built one of these great little engines back in 1977. I think you might be surprised at the power for such a small engine.

The teardrop file is sometimes called out as 'teardrop' in catalogs, pippin is the formal name. Handy to know when shopping for them. If one oft he sides is slightly rounded rather than flat, there are other names I can't recall.
