When i was serving my time as an apprentice engineer this was one of our college projects. The cylinder we made was from brass tube and plate which was then silver soldered. Brings back many fond memories of those days.
G Day Mr Pete, I am enjoying this series. The Whitworth thread is something the British left us especially on agricultural machinery here in Australia. Very similar to the UNC except for 1/2" and the thread form was 55 degree not 60. Whitworth spanners were different to everything else to with the spanner size often the bolt diameter not the actual head size. By not having them to deal with you certainly were not missing much. Thanks again.
Another great video, thank you. Whitworth threads would have been readily available when this kit was first produced and are still made today. Very, very surprised you have never mentioned using a Zeus chart. I use one all the time (especially when I need to translate American dimensions into a sane system).
When I saw the intersecting steam ports on the drawing I thought that sure looks scary! It was a pleasure watching you tackle that operation. Happy Easter to you Mr. Pete and family!
For what those kits cost you would think they would have decent drawings. With out your guidance most of us would be hard pressed to build this. Thanks for everything that you do, and great video shots.
I emphasized with your stress when you were drilling the steam ports. I had to drill two intersecting double blind hole on my Thompson 1/4 scale gas engine. LOTS of planning and a real Rube Goldberg set up on the mill. It was successful but NOT fun. Great Video!
Hey Mr.Pete I thought you might like to know I got my first lathe today. I got a clausing 4900 series lathe which is a 10x36 lathe. It needs some cleanup but I hope to get it working soon.
You made me leave watching all other channels and stick to yours.. Excellent work. I am not saying ( excellent ) for your work only, but also for your way of explaining how to use tools to avoid the problems rise though out the process..
Exactly, knowing _how_ to do it is just part of it, but being able to _teach_ it is just as important, (if not more), and only a very few have the gift of true teaching. Mr. Pete most definitely has this gift.
Love the videos, I have learned so much from watching them. I especially love the what is it series. I have watched them all. Keep up the awesome work!!!
Old school style Tubalcain footage! Recently finished a Stuart S50 engine, the valve box was so close to finished size and so hard, I had to rough grind then lap to size.
Thanks for this. At first I was disappointed that you had picked a wobbler, because I find the slide valve types a bit more interesting, but because they seem to have just thrown together a few assorted castings from other engines together with a photocopy of 100 year old instructions from some other castings and no drawing, it's been very interesting watching you work it all out. Mind you, I'd have expected a bit better from Stuart, considering the cost. I wonder how many more of their engines are like this.
Close ups are really great sir. That No.9 Steam Engine is one gorgeous bit of kit Mr P. Never seen any like it. My father bought us the small alcohol burner type in such small scale as to leave it a mystery as to how the valves worked. Never appreciated it.
This video brought back great memories working on the Stuart 10V and double 10V from 1968 to 1972. Your methods are excellent! My machine tools consist of a Unimat SL and a precision 6 in rule and square. Taps and drills purchased at Cole's Power Models. I talked with Charlie in 1968 for a few minutes. He was not feeling well and was gone one year later. I look forward to meeting him again. The crankshafts were one piece. Making end blocks for cutting the drive pins was a fine exercise. I prayed a lot and Jesus helped me! bobh
British Standard Whitworth threads are 55 degree threads; they were common when the engine was introduced. They still show up on some types on pneumatic/hydraulic fittings here in the USA.
Matthew Helton quite true. In addition to BSP fittings, the 55 degree Whitworth profile is also used on the BA fasteners that come with the Stuart kits. BA0 (largest BA thread) would be the same as an M6 thread if it weren't for the different angle.
I love your vids! Your a great teacher! I was all happy when u said u never heard of wentworth threads. And i knew what they are. Lol. My old triumph motorcycle had wentworth nuts and bolts. My old man still has the original wentworth tool kit. Thanks for sharing 👍
They are called Whitworth, but I understood what you meant, I only corrected it to help people search, not to complain about your spelling, because mine is terrible sometimes. Keep on machining.
Outlaw Edge Bladeworks Bushcraft and Survival the only reason i knew about Whitworth is because the spindle on my woodlathe has a 1 inch 8tpi Whitworth thread.
Briefly before whitworth there was no standard, he went around the UK and measured what engineers were making and came up with the Whitworth standard thread.
Hi Mr. Pete Thanks for the great videos After watching you do this engine I really doubt I would order anything like this from Stuart! I had paid for and received their catalogue a couple of years ago and it is a work of art. Too bad their kits aren't. I used to go to the Oregon GEARS show and every year they USED to have different casting kits for different motors. Being American Made they and the instructions were far superior to what you got from Stuart. Rod BC Canada
I have a small Emco V8 lathe where the chuck is held by three nuts on studs. Very little space between the headstock and spindle nose, not even enough to get a ring wrench in there. Compared to changing chucks on that little machine, switching out the jaws is positively _delightful_. Also, the chuck is driven by a square key, I haven't tried mine but shouldn't that be a standard ½'' or 3/8'' like on a wrench? In that case, you could even buy an adapter for the cordless drill, or else just quickly fabricate one, and churn out those jaws in no time. There's a cordless laying next to the lathe anyway at all times since the little thing has no mechanical cross feed.
Coming along nicely! I would of had quite the time figuring out how to drill the steam ports, but to be fair Im not a machinist. see you on the next one!
Hi sir, I am very facinated by your work and your type of homemade vice. Yes, you make a video to explain how to do it but it's a very heavy material and I can't do it. So, do you sale some of them? Thanks
I'd like to find some more tooling, specifically a belt sander, and one of those gimble center finders. I know that you constantly go to sales, and I wonder if you might tell me how to find them more easily. There isn't much in the rockford paper. Would there be much at the flea market at the Kane County fairgrounds? My folks used to go there for antique furniture back in the 80s and 90s, but I haven't been there since.
its the oscillation ark you need the plate to move line up move line up dont forget there is a 1/8 gap at the top of the cylinder or you piston will hit the cylinder cap so make you rod 1/8 shorter between centres
Something that has always fascinated me, why is it better to spin the work in the lathe, as opposed to setting the work in a fixture and spinning the tool bit? I know there has to be an obvious advantage, but it currently eludes me.
I have this casting kit on my to do list. I took a look at the cylinder casting and something struck me. I pulled out my 10v kit and compared the two cylinder castings. I think it is a 10 cylinder without the cores as opposed to what is displayed in the book.
G'day mrpete well thought out and enacted, especially considering that the drawings your working with are lacking in someways. Must buy some of those expanding arbors I haven't seen them before, thank you for the progressive videos on this little engine and the techniques that you are using, regards John
You've got me interested in machining my own model steam engine. Have to wait for the wife to leave town to order it, along with a 4-jaw chuck...wish me luck! By the way, have you ever machined a crankshaft from a casting (looking at the PM research engines). Wondering how to go about it.
Nice work! Great friendly poke at myfordboy too :D The cylinder bore and crank pin aren't quite aligned though, how is that going to be solved, a spacer at the cylinder or shorter bearing stub and thinner crank wheel?
I could always Learn with a good teacher When I was in High School. Problem was Back then some of the Vocational teachers Didnt like long hair on Young men , One Shop teacher event told me to My Face, You Long hair Hippys need to get a bath and a hair cut,,, I refuse to do anything with You ...then He laughed, So I left the Vo Tech class I was alway Clean and Kept My hair long But was taken care of ,
round nosed cutters give you a better finish were you can get it in points are ok for angles but were you can get away with it leave it rounded it looks better
Yet again another brilliant video ! Like you said I often feel like myford boy when standing at my myford ml10 lathe !! Keep up the amazing work . Happy Easter !
Whitworth? Surely you know that Mr.Pete? British Standard Whitworth (BSW) and British Standard Fine (BSF) would be what you would call UNC and UNF coarse and fine threads. And, of course, there is the 'special' category as well. Whitworth and BSF were the mainstays of engineering here in Britain, until we were forced into the Metric system when we joined Europe. (Thank God we're out of that at last.)
i just bought a atlas 10F -28 lathe do you know what HP motor it should have it has a motor on it but seems under powered can you also inform me about the belt brackets and the way its suppost to be hook up thanks Ric
Funny comment you made about feeling like myfordboy... when i first started watching you, I almost ask you if you ever heard of myfordboy. Because you to do so much alike. He says nothing or is quiet while you comment, advise , and explain. I must admit, I'm more fond of the explanations and comments from you vs reading his. Once again thank you for you videos.

you should have drilled the hole in the back plate before you faced it then you wouldn't have had to re position it yes i am a master engineer :P you do have a depth stop its called 0 :P

You are a smart man for working out how to drill those steam ports.
I am sure I would never have been able to do that.
When I saw the intersecting steam ports on the drawing I thought that sure looks scary! It was a pleasure watching you tackle that operation. Happy Easter to you Mr. Pete and family!
I'm really enjoying this series! Thank you!
Has with all your videos I am very much enjoying and learning.
Thank you.
All my best.

I liked the little clamp on the mill quill trick . I will be using that
For what those kits cost you would think they would have decent drawings. With out your guidance most of us would be hard pressed to build this. Thanks for everything that you do, and great video shots.

correct--47 1/2 deg

You're. Not "Your". Whitworth. Not "Wentworth".

THANKS
Hi sir, I am very facinated by your work and your type of homemade vice. Yes, you make a video to explain how to do it but it's a very heavy material and I can't do it.
So, do you sale some of them? Thanks
reason for the gap recess was to make sure the two plates have perfect contact points so there is no steam gap
Hope you and your family have a happy Easter .
THANKS

Hi Mr Pete, can you use a fly cutter also for the side of the cylinder where you used the 1" end mill? Thank you, Anton

Whitworth made the first standardised thread, before then people had their own different threads sizes which weren't interchangeable.
G'day mrpete well thought out and enacted, especially considering that the drawings your working with are lacking in someways. Must buy some of those expanding arbors I haven't seen them before, thank you for the progressive videos on this little engine and the techniques that you are using, regards John

My fear would be breaking off a small bit in a port, great job done
Can you mill a small clearance slot in the head(s) at the steam ports? Very good video; thanks, Greg.
yep-THANKS
Looking good.
THANKS
Nice work! Great friendly poke at myfordboy too :D
The cylinder bore and crank pin aren't quite aligned though, how is that going to be solved, a spacer at the cylinder or shorter bearing stub and thinner crank wheel?
THANKS
I wish I had A Metal Shop Teacher Like You when I was in Jr High I would have perused a Machinist Carrier and taken a metal Shop in High School
Thanks-wish you were in my class
He's our shop teacher now, and we're most likely learning more now that we're no longer teenagers that already know everything. :)
I could always Learn with a good teacher When I was in High School.

Thats sad
Hi Tubalcain , of topic could you tell me please what size motor for a heavy 10 southebend lathe ,thanks
great vids verry interesting thanks
1 HP, 1720 rpm, capacitor start
Any reason why you would not use a fly cutter on the cyl head to flatten it?
Thanks for sharing sir...
THANKS
The cylinder moved when centre drilling the port?
1/8th inch whitworth is the same as unf 1/8th I think or close enough for the girls that Ave goes out with?
you had that die makers square set at a slight angle 7:10
I know--hoping no one would notice
round nosed cutters give you a better finish were you can get it in points are ok for angles but were you can get away with it leave it rounded it looks better
Yet again another brilliant video ! Like you said I often feel like myford boy when standing at my myford ml10 lathe !! Keep up the amazing work . Happy Easter !

Beachcomber Bob I'm a big fan of Mr. Petersen' videos and I must admit I was a little surprised that he hadn't heard of Whitworth threads.
Happy Easter, Mr. Pete!
THANKS
Referencing the drill press statement at about 17:00. Is there any reason to have a drill press if you have a milling machine?
Saves wear and tear on a very expensive piece of equipment and the DP is more "sensitive" to your feel.
i just bought a atlas 10F -28 lathe do you know what HP motor it should have it has a motor on it but seems under powered can you also inform me about the belt brackets and the way its suppost to be hook up thanks Ric
3/4 hp motor. See your parts manual for the brackets-I know nothing about them
love it!!
a friend has drill press with double ends bite and it has tapper shafts drill press what do I need to make it work
don't know
i built a 1 cylinder oscillating engine for my school exam and a boiler got an A+
Funny comment you made about feeling like myfordboy... when i first started watching you, I almost ask you if you ever heard of myfordboy. Because you to do so much alike. He says nothing or is quiet while you comment, advise , and explain. I must admit, I'm more fond of the explanations and comments from you vs reading his. Once again thank you for you videos.
I think he is silent so non English speaking people can watch--gives him a wider audience.
that was a tricky bit to line up the port.
THANKS-yes

I've been suffering with the nightmare of whitworth since I was a teen.. TRIUMPH 500????
you should have drilled the hole in the back plate before you faced it then you wouldn't have had to re position it yes i am a master engineer :P you do have a depth stop its called 0 :P
set it backwards and drill to it :P
what a pitty that all is done in inches and not metric
but love what you do
regatds
steam bert
I think you meant to say "what a joy its was in inches" lol
or you could have 0 it on the edge halfed the width added it to the half the centre and 0 it and away you go :P
