Hi Mark. A masterclass in work holding and machining. The end result is definitely better than the casting. Your fettling was on point. 👏👏👍😀
Thanks. I have decided to replace the eccentric rod and strap with a more appropriate design as well. It will be a foray into 3D printed metal parts. Should be interesting!

Mark
For me, seeing the setups and how you go about machining the parts is the most interesting part of the video. I have a lot of "Oh, that's how..." moments.
Ditto 👍
Setups…. particularly for manual machining ( or ‘hand-tooling’) are what it’s all about Mark.
The world of ‘engineering videos’ is chock-a-block full of old/new ideas that indeed make one say .., ‘oh… so THATS how you do it’.
Thanks for taking the time to explain your thinking, and your steps.
Regards
Robert
I always appreciate the set-ups and fixtures used to machine the detail parts. And while you get prepare to show us I imagine how I might do it and compare the processes. It never gets old 👍👍😎👍👍
The thing about setup is that there's dozens of ways to go about making the same part. I have always thought it would be interesting to give an identical casting to, say, 10 different machinists and then see how they went about making the finished part. I am guessing that no two would do it the exact same way.
Regards,
Mark
Mark, that is a great idea. I think it would be well watched, especially if it was organized such that all the creators drop their episodes at the same time. And use the same hashtag so they can all be found.
At least for me, I love seeing how others have used the fixtures and scraps they have on hand. It inspires me to make creative use of what I have too 👍😎👍
I am one who enjoys watching chips fly. There are lots content creators doing that but many are pretty full of themselves. I like watching you and others like you--Stefan, Quinn, Tony--because of your self-effacing personality. In your case it was a gradual attraction. It took a few episodes for me to appreciate your style.
Thanks. I believe that it's best to be yourself. In the early days I badly wanted to be like This Old Tony but I think his style is very hard to copy. Now I take the view that I will just do my own thing and invite others to look over my shoulder while I do it. I am glad you enjoy the content and it's always nice to get feedback on the quality of the videos.
Regards,
Mark
As many others have commented, the setups and choices which you make are very informative. As a beginner, it amazes me that there are so many alternative ways to achieve the desired result.
That's the fun of model engineering. You can choose your own adventure!
Regards,
Mark
Mark, thank you for sharing your set-ups, jigs, fixtures, & processes regardless of what the project is. I receive a couple of (U.S.) machining magazines which often have firearms repair/modification articles, but not needing to repair or modify any firearms, I still read the articles because the set-ups, jigs & fixture ideas, & processes apply to all types of machining. I always learn from watching your videos and those from other Content Creators too.
Thanks Bob. I used to read the really old Model Engineer Magazines from way back in the 1940's. So much useful information and although a lot of it was really specialised, there was always some little technique that could be adapted. A lot of the time it's about thinking laterally and not getting too hyper focussed. Sometimes taking a step back and "ruminating" delivers the answer. You will see in the next episode how this helped me to solve a problem with drilling the valve rod guide for the steam chest.
Regards,
Mark
Looking really good Mark. Fun to watch your set-ups on the different parts to machine them.
Thanks for sharing.
Quite the multitude of setups. That's one thing I spend a lot of time thinking and rethinking is how to set up a part for machining. Which has proven to be a good thing, since I change my mind and come up with better, less complicated ways to accomplish what I am setting out to do.
I know what you mean. My wife and I go for a four kilometre walk each morning. It takes us about an hour and we don't talk much. It gives us plenty of "thinking time". I spend the time thinking about what I need to do during the day and most often I will come up with a solution to a machining problem or a fix for a part. It's great.

Mark
Mark: "Mark you're an idiot" 😂 Following your channel for years now and it inspired me to finally take on a 'turning and milling' course. And I'm loving it! Can only dream of ever becoming as 'idiotically' skilled as you are! Great content as always and thank you for the inspiration!
Many years ago I visited the Smithsonian Museum. I was especially fascinated by the Industrial Revolution display, which featured an antique steam engine that had once powered the looms in a textile factory. The thing that struck me was how eerily quiet the engine was while running under steam power.
I have seen some of those old Victorian era engines running but I often wonder what they would sound like when they were really working. Often the engines on public display are just ticking over. I had the pleasure of seeing a large horizontal steam engine powering a sawmill back in the late 70's. It was coupled to a locomotive boiler and the mill was cutting heavy Australian hardwood. They used to use the sawdust as fuel for the boiler. I will never forget the smell and the sound of the exhaust.
Regards,
Mark
Mark, You are correct that the skills are transferable to other mechanisms. Your setups are similar to that I have used to restore antique firearm internal parts. Well done!
When I was teaching kids in secondary school we would tell them that there were "fundamentals" of working with wood and metal. Mostly, it was about marking out, drilling, cutting, finishing workholding and joining. The skills were like tools in a tool box and with experience you know which is the correct tool to use to get the job done.
Regards,
Mark
That is a lot of steps, expertly done.
This is great Mark, looking forward to seeing more. I was told to come follow you as I have just got this very same static engine from Stuart. It was given to me but I didn't have the plans with it, but seeing how you've been working on it I'm confident I can assemble it now.
Look forward to seeing more and I'm following your channel now too. Thanks mate and I'm totally setting up an idiot shelf for the bodges 😆
I can send you the drawings if you like. I scanned them and laminated the sheets so I wouldn't damage the originals. In fact, I just put them on my Dropbox account www.dropbox.com/scl/fo/7b62phr5kr6i7e85wsa1r/h?rlkey=2jfjd3yc1e6avrgynbg1jqcob&dl=0
The original drawings were on A3 sized paper sheets but I only have an A4 printer. However you should be able to work it out.
Regards,
Mark
I always enjoy your videos. don't beat yourself up over the mistakes. I'm sure a lot of sidetracks happen while videoing, easy to make a mistake. you produce great videos and great material
Thanks. It is true that having a camera running and constantly having to check the framing and whether it is actually recording tends to be distracting.
Regards,
Mark
Great video Preso, these kits are amazingly challenging with regard to techniques and accuracy. Watching you finish that part so gingerly brings to mind all my pieces in the corner of shame due to my reckless finishing. Enjoyed, take care and cheers mate!
My issue now is being able to actually see what I am doing. On tiny parts it's hard to get any feedback on where the line is or where the metal is coming off. Having a camera in the way doesn't help either.
Regards,
Mark
You’re not an idiot, you’re just relatable.
I still get angry with myself though. Having a camera running divides my attention. When I turned the camera off and made the second set of bearings it went perfectly.
Regards,
Mark
Beautiful workmanship 👌🏴
I lust over your newest “tool”. What a timesaver! You are going to be using this a lot more. If the software is as good as the DRO stuff currently available, it will take a considerable amount of time and effort out of setup. Congratulations! In your talk at the end of your video you say that the manufacturer claims that it can be built with minimal tools. I remember as a very young child my father rebuilding the Packard with a rod bearing gone using a 9/16” ( if memory is correct, it was around 65 years ago) a crescent wrench ( adjustable spanner to British Speakers) a pair of pliers, and a tire iron. The language would have made sailors blush, but was essential for our survival. It was successful, the post WW2 classic ran many miles after. Finally replaced with a 52 Packard. Now I received an education in survival mechanics that has gotten me through a couple of careers from those lessons……. But I’m positive that proper tooling makes for longer lasting assemblies. Static acceptable display models I assume is the intended meaning. Viable working engines is what I am sure your followers are looking for. Looking forward to seeing how you are going to do the flywheel / crank connection 😊
That's interesting about the Packard engine. I remember reading an article about how the mechanics could repair or rebuild worn or damaged vintage engines using mostly hand tools. With modern, high performance engines it's probably impossible.
I do want to make the Stuart 10H engine a working engine running on steam. I am playing around with the idea of having it run either a centrifugal pump or a dynamo. Boilers are hard and expensive unfortunately. I want it to run on coal too so that's going to be fun.
Regards,
Mark
Love to see these parts come to life and together. As a youth I went to the British Science Museum in London and the best part was the ground floor with all the steam engines, mostly static but one or two running on live steam. Magical.
I also love seeing those old Victorian era engines. The ornamentation displayed on what were essentially industrial engines indicated that the engineers of the day were proud of their work. It's somewhat lacking in modern manufacturing.
Regards,
Mark
Loving the build Mark keep up the great work!
So interesting. Thanks, Sir Mark!
I have always liked the small engines, good to build, easy to store and show off. Keep up the wonderful work Mark, great source of entertainment, beats TV any day !!!!!!!!, Regards Mike from Cornwall, UK
I used to have a Shelf of Shame. I had to upgrade to a Hall of Humiliation.
I think we should celebrate our failures. I think it has been stated before, but if you aren't making mistakes, you aren't making anything. 😁

Mark
The art of model ingineering I like the body of the connecting rod in steel. It's realistic. Great work Mark. Impatient to watch the next episode....
I love a good Ole fashioned steam engine build! I love seeing chips come off of anything but imo anyway the more niche the better and the complexity of a steam engine definitely satisfies my curiosity, even though I've seen it done before, so thank you for making this series!
You're welcome. I am glad you are enjoying the build.
Regards,
Mark
Great work as usual Mark. Keep doing it the way you do. Everyone loves watching setup & machining as you do.
Steve.
Thanks Steve. When I was training at college, my machining instructor told us that making parts was 80% setup and 20% shifting metal. That still seems to hold true.
Regards,
Mark
Thanks for that, I like your version of the crankshaft 🍻
Thanks. I like it too. I think it has more integrity than a fabricated crankshaft.
Regards,
Mark
I was holding my breath during the center section turn down...well done Mark ! Looks awesome 👍👍
Cheers.....
Me too. One wrong move and it all turns to a mangled metal pretzel.
Regards,
Mark
Educational setups on the con rod. Notes taken.
Well done as always Mark. Fascinating to see the methods to create the whole. Thanks!
Very challenging parts to make. With a lot of "thinking before cutting" moments.
Thanks Michel. It was one of those lightbulb moments when I realised how the rectangular bar stock was the best way to proceed. We had our Belgian dinner party last night. The Carbonnade Flamande was sensational.
Regards,
Mark
@@Preso58 "Stoofvlees". Very good :)
I've been reading a book that refers to a war between superpowers using an EMP (electromagnetic pulse) by setting off a nuclear bomb in the upper atmosphere, resulting in the destruction of all electronic circuitry. The steam engine and those with the knowledge to build one now plays an extremely important part in saving humanity. (The book is titled "One Second After" by William R Forstchen.)
I wonder what might happen if all the GPS satellites are destroyed by a collision in space. So much of the day to day technology that we rely on will stop working and we will never be able to clean up the mess so maybe we will have to go back to simpler technology.
Regards,
Mark
Enjoyed
Very interesting approach to making the connecting rod and bearing, beautiful work.
Thanks Nigel. I am glad I didn't go down the road of trying to make it out of round bar stock. That would have gotten way to complex very quickly.
Regards,
Mark
THOMAS DALTON WALSHAW great man top engineer.
Thanks for that. I must say I did not know his real name. I just looked it up on Wikipedia. He was certainly a prolific contributor to the Model Engineer magazine.
Regards,
Mark
Very exacting! Great work. Always enjoy.
Well, hello there! Nice to catch you on time for a change...
Got me intrigued untill u turned that square bar in the lathe to make it into conrod very clever and a bit of thinking there I can see ...coming along nicely looking forward to the next one awesome job thks ...
Thanks. I almost made that part the hard way. Sometimes some lateral thinking pays off.
Regards,
Mark
Love the complex setups Mark. Don't understand why you're ragging on the parts on your shelf of shame, it's not their fault that they are there 🤔 😁😁😁
Thanks for sharing
Cheers
If truth be told I am celebrating my failures. 😁 What is it they say, "If you're not making mistakes, you're not making anything".
Regards,
Mark
Keep up the engine building Mark, I have a 10H to build yet and I’m always interested in how someone else approaches a task and whether it is different to how I’d imagined doing it myself.
I am glad you are finding the series useful.
Regards,
Mark
Gday, absolutely beautiful job mate, cheers
Thanks Matty. Man, my eyes are having problems with some of the tiny detail on this engine. I am finding myself reaching for my Mr. Pete magnifying visor more and more.
Regards,
Mark
I was not really interested in another steam engine build. Except the stories you tell, no matter the content, are such a joy to watch. Thanks for sharing!
Thanks. I'm glad you are enjoying the content.
Regards,
Mark
Nice work, I'm running out of projects and I'm seriously considering making something along the lines of this, but making all of my own castings using lost foam Aluminium, as I have around 10kg of scrap casting to use up that I bought, of course, it won't be a steam engine and will only run on compressed air. On another note, I find in my UA-cam analytics, that even though I tend to speed up my machining to 12 times normal, viewers are just skipping over it, oh well, that's life, you can't please all of the people all of the time. 👍
There seems to be very fine line between including too much tedious machining and skipping too far ahead. Some people just like to watch the chips coming off and some are wanting to see the finished product. As you say, you cannot please everyone.

Mark
Mark you talked in previous video about calibrating your touch probe …. Can you on comment on how well it maintains its calibration… I have a similar one, different make, and I have found it needs re-calibration far to often … or at least checking, I have used it to find a center or some datum only to later discover it was out of calibration enough to ruin a part …. Let’s know if yours does better… guess I have become gun shy as far as inexpensive probes are concerned and now I am sticking to good old fashioned wigglers… I’m really enjoying your current series
What I only found out a few days ago, is that the accuracy is only as good as the tramming of the column and head of your milling machine. I was making a short video on how to set up a touch probe on a Sieg X3 mill that I have converted to CNC. I knew the probe was accurate because I swept the tip of the probe with a DTI and it was only about 5 microns out. However, after probing the centre of a ring gauge of known size I put a DTI in the spindle and swept the inside of the ring. It was about 0.12mm out of concentricity. I went through the process again and the second time it was about .06 out. The second time I didn't extend the quill of the machine as far and all of a sudden the penny dropped. The column on my mill was out of square with the table. I checked it with a large angle plate and a dial indicator on the head of the mill and there was significant error. So, depending on where you put the probe in relation to the work you will get a different probed position. I now have to shim the column of the mill. Bridgeport style mills can also give problems that look to be like calibration errors in the probe itself when it is probably related to the head of the mill not being trammed accurately to the vice or table. There may be other reasons why the probe isn't holding calibration and I have heard advice that you should check the probe with it clocked 180 degrees from the position where you would normally hold it in the spindle. Maybe the four screws which are used to centre the stem of the probe are loose? The probe tip might be bent?

Mark
Amazing! I saw an advertisement recently for Presling and Pie Discount Brain Surgery. You guys moonlighting??? !!
That's news to me. 😁

Great video agian. Great build. Did you say the piston was brass? Steam and brass don't mix well. The steam will leach out the zinc in brass over time. Bronze or cast iron will better for you. Cheers
Unfortunately, the drawings do not specify which materials are supplied for each part. There is a piece of brass in the kit that is roughly the correct size and there is also a piece of malleable iron which I assumed was for the eccentric. The Stuart number 8 engine was supplied with an iron piston (and iron piston rings) but this one is a bit lower spec in a lot of ways. I may end up substituting some cast iron for the piston.

Mark
It’s a fantastic project, excellent job. Is that hissing in the background insects, or an editing issue? It’s just quite irritating. Thanks for sharing.
I must say I don't notice it but then again, I don't use headphones and I probably have some hearing loss at my age. I will check it out though and see if I can identify what the noise is.
Regards,
Mark
@@Preso58 sorry but I’m watching on an IPad without earphones. It’s on all your videos, but when a machine is running the noise is gone. Oh and I think we are about the same age I’m purely guessing. Thanks
Nice Work! An i can tell you... it is possible with hand tools. The first machine, was not build by a machine! And so on....
Thats what drives me....
Cherrs!
Thanks Chris. It's amazing what was achieved with hammers, chisels, files and hand driven drill bits.

Mark
Hi Mark I really enjoy watching your videos I have learned a lot about machining from watching UA-cam I am new to machining myself but have come to love it I watched one of your videos about the touch dro an contacted Yuri about it and he doesn't make the one for I view scales anymore an I seen you still have your old one would you be interested in selling it?
For what it's worth, I would urge you to go for glass scales. I know the cost is a factor but they are far superior. Yuriy stopped selling the adapter for the capacitive scales because they were problematic and the manufacturers kept downgrading the refresh rate. I do still have the old adapter but I thought I would keep it for a less critical application like, for example a fence scale for a circular saw or a drop saw.
Regards,
Mark
Hey, everybody is entitled to some mistakes.
Fortunately I don't do UA-cam videos so my Bozo moments and shelf of shame can be ignored with Beer if required 🍻The current TIG welding job......... is somewhere around a 6 pack so far today.
It would be great if I could just bin all the rubbish parts I have made but the thing about making UA-cam videos is that even if I were to substitute another part and say nothing, some eagle eyed viewer would probably call me out on it.
Regards,
Mark
One of the things we like about channels like yours, Blondihacks, inheritance Machining, etc., is that you show your mistakes. There is much to be admired about people who don’t edit out the goofs. It makes you more relatable, because we all make goofs. One tends to learn more from seeing why NOT to do something a certain way than one does from seeing it only done perfectly once.
Great work on the engine, Mark! Looking forward to seeing it running 😁
@@Preso58 You learn a lot from your mistakes, but it's the truly wise man who learns from other peoples mistakes. Thanks for making wise! Although I do learn a lot on my own!!!
You have a shelf of shame, Inheritance Machining has a box of shame, if I kept all of my mistakes I’d have to add an annex.
We all make scrap parts. It's part of the learning process. Best to celebrate it!

Mark
Thank you Mr Mark Presling.
I like to watch your videos because they show very sensible processing steps.
