OLD STEAM POWERED MACHINE SHOP 27
HTML-код
- Опубликовано: 15 окт 2024
- Number 27 in a series of my shop, set up to depict a small operation job machine shop of 1925 operated mostly by steam power. Using junk wood and soft coal for fuel I do "general machine work" as probably the only revenue generating machine shop in North America under steam power. With the arrival of the bigger engine, the smaller shop engine will be reassigned to make electric power for lighting. Old machine work requires thinking in 1/64 ths, class of fits, measuring and working fy feel, and thinking things through. Discussion of Steam power, machine work, line shaft drives, etc. is always welcome here......Dave

David, I love it all. I have to admit that I am a gear head. Everything about your shop fascinates me. It is almost as sexy as Marilyn Monroe. Almost. Not Quite. And I agree with several others about the slide rule. That is what I started Engineering classes with. A calculator had a handle like a slot machine with a hundred push button keys and you didn't drag it to class. Thanks so much for putting these videos about what you are doing in your shop. Too cool!!
David, Awesome video & content thanks for sharing your video, hope your having a great day.!.!.!.
That 26 minutes wet unbelievably quickly.

Those machines and oldschool techniques just awsome. I found my new favorite channel. Thank you, sir!
My grandfather was the boiler room foreman and head mechanic at Rogers Peet, a clothing store and manufacturer in the Bronx., N.Y. They had their own coal fired steam powered generating plant. He and his crew had to stoke 16 ft. boilers by hand!! I still have some of his books and his pipe threading tools which are similar in appearance to some of yours. I love the slide rule, I have one like that. I learned to use it and do exponential notation before pocket calculators came out. When they did, the other kids ' calculator batteries would die in the middle of a test. and I was still working away and done ahead of time. I still use it! Thanks for posting!
Can't say enough how much i enjoy the channel. You have guts in the face of easy and quick, and love to show us how it was done. Thank you for the timeless examples and education. RUclips will help preserve what you have shared. Camera and sound work are excellent.
Thanks for the kind words...Dave
Dave, thank you so much for your videos.In todays world its so nice to see someone who takes their time and enjoys what they do. Its so peaceful to watch you work.
Hello Jake.
The interrupted cut on that large pulley really gave us a good look at tool deflection each time it picked up the cutting load.
Last winter I dug out my old slide rule during a housecleaning binge. It must be 50 years since I used it for any serious work; can't even remember what half the scales are for.
Keep up the good work; the old iron is fascinating!
They just get better and better. Thanks again Dave.
I grew up with slide rules and own three right now. I do not use them every day but for rough-cut calculation they are much faster than calculators, and you can see all the numbers. Never thought I'd see one on YT. As usual, fascinating. Thanks for posting.
Its 50 years since I used a slide rule TOTALLY forgot how to use one just shows what you don't use you lose.great vids Dave ,cheers.
YOU ARE GOOD AT WHAT YOU DO. THANKS FOR SHARING.
ahh yes, slide rules! back in 1967 I started Engineering classes at Youngstown (Ohio) University. my very first acquisition was a top of the line Pickett slide rule. then later on I had to take a 1 credit course in how to use a calculator - the good old days indeed!
Little by little...coming along nicely. Thanks for the videos.
Hi Duncan, Hopefully some time I'll get everything set up and running the way I want it to......Dave
Best to take one's time and get it right than rush it and get it wrong I'd say.
I suffer withdrawal pains waiting for your next episode!!!!!
Thank you for providing them.
I love the steam engine as a power source-----to me is seems so much quieter than electric powered tools, also the old equipment that you use never wears out and rarely breaks down.
Also I love the idea of almost free energy to run the shop, would be great it the lights were steam operated.
Nice variety of tasks in this episode. The pulley ratio equations were interesting - Thanks
Got to love that knob and tube house wiring you put your hand near when winding the clock. when I bought my old house the knob and tube come up in the underwriting for the insurance policy. They were very insistant that if there was any, it had to go. I hope the insulation is up to date or the circuit not energized.
That said I absolutely love your content and projects. Great videos! I look forward to each one.
Glad you took all that math. I think I could stoke the boiler and keep the oilers full. Good job as uauall, Dave! Thanks!
Great video. I have a slide rule, not that I ever used it. I acquired it from the estate of a man that really did use it. I remember the slide rule from high school and my failed attempt at drafting or mechanical drawing class. I'm 79 and most of those brain cells have been put to use on other projects. I salute you sir and all you do in your line of work. Makes my heart jump when I see you have uploaded another video, they never get old or boring....Ken
Thanks Dave. Your videos get better and better. Your a busy man with all those projects going on. Wish I could help, would do it for the experience.
Hi Dave, I really enjoy your videos and look forward to each new installment. I recently restored a 1913 Vulcan Engineering Sales Co. Q &C Standard Power Hack Saw. Cast into the top of the saw bed was “60 RPM”. The saw appears smaller then yours but has the same stroke.
The saw along with tools for a complete metal working machine shop, wood working tools for a pattern making shop, and blower and equipment for a cupola foundry for casting iron were all purchased from Sears in one order in 1913. Amazingly this was for a small farm shop located in north central South Dakota. The family, still has the original invoice listing every item down to the individual drill bits. A 6hp Economy engine, purchased at the same time provides the power. I have included a link to a drop box containing information on the shop, the equipment, and the families patents and inventions. The shop is now located at Prairie Village near Madison SD.

The research and information contained within the drop box was compiled by the original owners great granddaughter.
Just wanted to say I appreciate your steam whistle. It's reminiscent of the steam whistle in the naval shipyard I worked in for decades.
Dave, thanks for this great video and keep up the steam too
you have helped to stoke my interest in steam even more I know one of the first projects for my shop when I get set up will be model steam engines thanks again for keeping the craft and trades alive
have a good day and a better tomorrow
I very much like the video. You do a great job teaching. But I really want to complement your video production. The quality of your intro and exit is just super. Beautifully done. Beautifully understated. Fascinating to watch. Makes you want to get comfortable to watch the video. Thumbs Up!!
Thanks Dave, top shelf. One of the most entertaining machining channels on the net.
Hi Dave .,.. I have been re-watching all of your videos and am enjoying them all over again. Just wanted to say that I have NO experience with a slide rule but your explanation was so good, I actually Got what you were saying. My hat's off to you, Sir and thanks for all of the entertainment and knowledge. Russ
Hi Russ, It's nice to know there is someone interested in this old stuff besides me!...Dave
@@davidrichards5594 Thanks, Dave ... I have had an interest in steam engines of all types since I was a boy in the early 50s. Learning about machining and watching all the Greats, including you, on You Tube has been a pastime for me for the past 10 years. I grew up on a farm and an apple orchard til I was 18 and then struck out on my own to make my own life... I know what hard work and dedication look like and I see it in you through every video.
Thank You for taking the time and trouble to show us your work and beautiful shop. Russ
You know Dave, when I first saw your shop I didn't think you could make it much better.....but hey going to be 100s of times better. Excellent video as ever. Slide rule....I had one at college, even forgot they existed lol. Really hope it all goes well for you :)
Absolutely brilliant - again! Everything about your shop is superb - the clock, the electrical wiring, the scales for measuring your balancing weights, all the little details that make it such an authentic steam-powered shop. Thanks for making such high quality videos.
Hi Dave, love your videos. That said, I've never seen a clock wound counter clockwise before.
Same here
Glenn Martin Haha, David has quite few things I have never seen in my life. The clock is the most easy to understand. I have an old Cold War era ICBM bunker clock... Property of US government even :o) and that one wind up clockwise, prolly like most clocks do :o)
Eric Corse
Come on guys it's a time machine you wind it clockwise for the future and anti-clockwise for the past , else how does the steam power workshop function 😊
Just joking guys great video again Dave
Boy that slide rule made me feel old , started with one then used logs until these silicon based thing came along , remembers having to put a margin on the page for the logs to show the examiner how you derived the answer if you where pushed for time in the exam making your answer slide rule
Stuart old codger
I should have thunk of that
Hi Stuart, It is amazing though, how close you can estimate the last place if you keep it clean and adjusted....Dave
Hey Dave, another fabulous video. Love the idea of putting a steam trap inline with the new engine... Always looking forward your next video. Thanks too much.
thanks Dave for the great videos.
Great vid again thanks so mutch for taking us back in time
lee jones i
Very informative... looking forward to #28. Great Job.
so glad i found your channel !! found it because of a love for steam engines , but have always had a love for machine work ! my grand pa was and Amish black smith .and had some interesting tools for measuring wheel rims and i remember old steam power engines as power units for thrashing ,on wheels , pulled with a team , before they went to cut down john deere s
Thanks for the clock shot, Dave! Another great episode. I really like the opening sequence. Artful.
Your videos are the highlight of my days. I don't get out so much now, so I appreciate what you do.
You have a great shop Dave and I look forward to your videos
A slide rule?I haven't used one since 4360's were pullin 3500 brake horsepower at 247 Ft lbs of torque NACA day.Yes now your getting us to think.Yes I'm that old.Thank's for the trip down memory lane
Love your videos, the feeling the clock, the topics are all really entertaining and relaxing actually. I cant believe you pulled out a slide rule, I've never seen one much less the way you whip it out and casually use it like nothing!
David, I love your shop. I am 28 and have had a fascination with anything steam powered. Watching you work in a steam powered shop makes me giddy like a little girl with new clothes and candy. My only thought process is I hope you move exclusively to working on steam powered everything and continue posting videos.
Seriously thank you. For taking the time and posting the videos.
One other thing have you thought about building a condenser for the steam exhaust?? And recycling the water??
Thx , I love your videos ! They seem to take me back in time when everything wasn't expected to be instant.
Great video! Look forward to your next one!
Thanks for the update Dave ,I keep looking for your stuff and am never disappointed....
Thank you for another great video, always great to watch
Hello from Australia. I have been watching your channel for a long time now and think it is great. Your shop reminds me so much of how I used to work. I did a Fitting and Machining apprenticeship back in the early 70's for a company called Ross Robbins. They got a contract/Licence to make Dreadnought industrial Valves shortly after the start of WW1 and they just kept on making them. In the shop I worked in there was an old Ward (I think 3 ) Capstan lathe that we would start up from time to time to produce Gas Cocks. It was overhead belt driven with exposed 4" lather flat belt. The drive had been modified from a overhead common shaft to an electric motor mounted above the lathe. When we engaged the drive pulley it would make the same sound as the Door bell on the Adam's Family TV show. Why we used this lathe ? it had Bronze bushing in the head stock so when we machines the long tappers in the gas cocks we got perfect seats (no chatter). Here is another thing .. we all had mostly our own machines, we knew how to work them to get the best out of them. You have a very good channel.
Thanks for the comment Charlie, Sounds like you all really"knew" your machines. I've heard that plain bearing spindles produce better work on some things. I've never owned a roller bearing lathe....Dave
Hi Dave,
I could watch your videos for hours.
THANKS!
I liked this before i even saw it...he he...You really bring so many people joy for making these great videos... Your passion and smarts are inspiring! Personally I cant thank you enough for taking the time to make all these for us. You really are one of my favorite shops. Its such a treat and i know the videos take quite an effort..and you are doing a great job with the production too... The shots are beautiful and well framed and thought out...Cheers!
OOH nice slide rule!
excellent
Loved the slide rule. Took me back 55 years to my High School days.
Wow 55 years, just 51 for me.....Dave
Glad to see another video so much to learn from them . Thank you
Great job
David, the "dial gauge" you used for centreing in the four-jaw chuck is wonderful. Things such as that would encourage young chaps to be careful with their tools.
It's such a delight to see you working in your shop with the old machinery and also improving it staying true to old style and ways.
Thank you so much for sharing!
Love the old old house wiring!
David, I loved hearing the soothing sound of your clock in the background so much, I had to get one for mine too! Thanks for the great videos!
G'day Dave just when you thought algebra was a forgotten maths out come a "slide rule". Seriously Dave very interesting video and how you set up the pulleys, there's more to it than I imagined. Thank you once again John
1st time in 40 years I have seen a slide rule used .I still have one here somewhere i have had for 50 years. :-)
Thanks David for the great vid! Your natural abilities as a cinematographer are showing! Great editing! Thanks and greetings from Vancouver canada!
love it thank you for sharing Dave.
First slide-rule demonstration I've seen, and I'm not a kid. Makes me wish I had learned to use one. Odd question--That angled tool rack you've got in the middle of your shop. I'm curious what the philosophy/history might be of that thing. At first glance I thought the slots were to be used like some sort of French cleat system, but it looks as though you've just driven a nail wherever you want something. So is it just a convenient mini-wall built to a design that assumes no sheet goods? Thanks as always for the great content. Big thumbs up.
It is a much smaller version that was totally inspired by the one in the end of the East Broad Top Railroad machine shop. It could have gone back to 1882 then when they put up a shop or 1904 when they "modernized" it. Thanks for watching....Dave
Gear trains and pulleys.. one place where a slide rule is better than a digital calculator. It allows you to see at a glance what combinations will give the desired result... especially if you have an assortment of gears or pulleys and want to see if what you have will work without the expense of new components.
Bonjour David,
Why do you use a 4 jaws chuck for round pieces instead of a 3 ? It is always a great pleasure to watch your videos.
Amicalement, Raphaël
Thanks Dave, I really liked the laid back pace on this episode!
can´t wait to see the big one running !! thanks for your work
This is so entertaining!! I´m eager for the next episode and for the big engine first run.
It hasn't been all that many years since I ran an old paper machine that was built in 1901 and it was driven by one small steam turbine. In addition the 125 foot line shaft had 7-8 drive belts running up though the floor above.
The newest of these machines was built in 1964 but now the whole thing has been scraped and the site is nothing but a field in the banks of the Mississippi River.
Dave Richards perfectly personifies Americanism.
Great video! I would love to see a shop tour. Thank you
Awesome videos Dave!
I worked on a bunch of knob & tube house wiring back in the day.
Another great clip Dave thanks!
It will be good to see the hack saw running off the line shaft as well as the shaper when you get to that . Could you maybe show a bit more detail in how all the shafting is hung , like how the bearings are held in the hanger you had cast?
Looks like you should store your step stool you were on at the end over by your clock for winding it..
OH ya it may of been 7th grade algebra when we went to school but now I am afraid it is college level common core math.
Ahh, Great share .. I ENJOYED !! I am on to 28 >>>>
Great job. Dang it now i have to dig through my stuff and find my slip sticks.
Absolutely brilliant, can't wait for the next one. You are the best. How easy is it to get hold of pulleys? Are they still being manufactured? Are any youngsters interested in carrying on the work in your shop? Will your existing boiler provide enough steam for the big engine? Any plans for a superheater? Do you treat the water for your boiler with, for example, tannin or do you use rainwater? Did I tell you that I am making a model Yarrow boiler?
Colin: To answer a few of your questions, I get old pulleys I like at engine show flea markets, etc. and I'm pretty sure you can buy new stamped steel "split" flat belt pulleys from industrial suppliers that have the different 2 piece hub bushings for different size shafts. I'm using one of those on my big lathe drive. At the load it will be running against. the hoist boiler will be more than adequate to run the bigger engine. I use a boiler treatment called "Boiler Saver" from Jim Conte, you'll find it on line. I use rain water adjusted to about ph of 9. ...Dave
GREAT VIDEO !!!
Hi Dave - Love the videos! You have inspired me to get a lathe and start learning - I am in the process of buying a South Bend 9" Junior nearly identical to the one you showed in your first video. Any chance you could spend a few minutes in one of the videos showing it in use? Thanks for all you do - its an inspiration to us folks just getting started!
Thanks, Tom and I have made a lot of parts on the little SB in earlier videos.....Dave
Hi Dave,
Everybody has already made my comments: fascinating topic, great video work, relaxing to watch, and it just flew by.
Always ready for the next one.
Joe
PS I for one would be more than happy to support you on Patreon if you ever decide to go with that. Just let us know.
Looking forward to the Racine Saw. I have one that is almost identical but with cast iron legs rather than the cast iron pedestal box you have. Mine is of WW II vintage and has the War Ordinance department tag still on it.
Mine is WWI vintage and you would think yours with cast iron legs would be older, maybe the box base was for models with coolant, mine has a reservoir in the bottom....Dave
Hello David,
I have enjoyed the video as always.
Greetings from fryslan
Great physics math lesson! It's why machinists are engineer's.
Would it be practical to build a convection superheater to go in the boiler exhaust to increase efficiencey and help dry down the steam for use?
Did you get this comment Baily approved??
Dave,
I recently found a working Waltham watch company grandfather clock in excellent condition using three liquid Mercury weight vessels. Unfortunately the gentleman that owns it isn't interested in selling. Top to bottom is roughly 9 1/2 feet with a long timing weight. I used to work for the Boston and Albany Railroad and the clock has printed on the clock master clock for the Boston and Albany Railroad. He said he bought it They were demolishing the building and the demo foreman said you want it ? Get it out of here , you have one day.
It's gorgeous. And it still has the electrical contacts that the telegraph was hooked up to to time all the other clocks on railroad property used that signal to be accurate time wise.
One of these days I'll find one for myself.
Let's see more of the drill press. I just picked up an old Barnes 20 inch..
I think something is coming up with the drill press....Dave
Great video Dave. Dave had you thought of buying a commercial steam trap? I know it's new, but they are very efficient. Another thing is steam pressure, what pressure will you be running? Can't wait for that new engine to be up and running. Sorry another question, is the shop going to be full when you get all that equipment up and running?
Great video David! Thank you.
That helps me a lot in figuring out speeds on my own line drive.
Is there a reason for running the main shaft at 240 rpm or is it just what you happen to use?
I'm also wondering what the horsepower requirement is for an engine to run your size of setup?
Jim, I'd suggest 240-260 for a large lathe. You can run faster on a small lathe like a 9". The small 5 HP steam engine ran the whole shop with no trouble at all. A 5HP electric motor would probably be minimum. The big shop engine is 60 HP, but I run it at 90 RPM with only 70 psi so You can see it's very big "overkill".....Dave
hey pretty cool set up dave. you are a wild man on that slide rule. is there a book on steam engine design that you could recommend? thanks for posting.
Bonjour David,
Alawys a pleasure to watch you videos; I am familiar with metric measures and I am not able to understand yours. Never mind as soon as you can :+)
Amicalement, Raphaël
Hi Raphael: Well.. if Mr Metric had got on the ball first, we wouldn't have all this nonsense with 59/64ths and 13/16ths......Dave
lets see 59 divided by 64 = .921875 divided by .03937= 23,41567183 mm simple 4th grade math lol
Bonjour James,
Excellent !
Amicalement, Raphaël
lol, only 2 or 3 countries in the world, left that haven't switched to metric. Come on america you don't want to come in last do you? (Even your world famous space agency nasa has switched to metric)
Bonjour Billy,
I have been several times to America and have been a bit lost with gallons for my rental cars and tips to be added after the taxes (In France, when you pay a bill, everuthing is included) :+)
Amicalement, Raphaël
as always great stuff David. i can't wait for the next video!
Really liked the rhythmic cutting sound at 11;02. It sounded like "Hillary in prison, Hillary in prison"!
Hello again Dave,
Are you sure that you should have used circumference to work out the RPM? A power hacksaw cuts linearly not circumferentially, so on a 6" pulley you have the saw's connecting rod going through 6" from the 3 O'Clock to the 9 O' clock positions. Every rev gives you 6" (ignore the non-cutting return-stroke) so for 135 feet per minute you need 135 x 0.5 ft = 67.5 rpm. Not a world of difference in the real life, so nothing to worry about. Am I correct or have I missed something monumental here? Keep up the good work I simply love your videos. Steve
What is the make and model of the small blue drill press? I'm looking for something similar but having trouble finding anything. Love your videos and you have inspired me to build a similar but smaller steam shop.
Dave: Great video, again. Every time a new one comes out I drop what I'm doing to watch.
To drain the condensate out of your steam separator (which I what I would have called that device) wouldn't a bucket type steam trap do the trick? It'll only open when there is enough condensate to activate it. I haven't bought one in forty years, but I bet your plumbing wholesale supplier can put his hands on one, no?
Carry on, brother!
Nice detail on the shop wiring, different type of insulators that were used here in NE Indiana knob and tube were the standard here. Was the knob and tube type used in NY ?
Thanks for the comment Allan, The insulator design changed a little through the years and there were different brands that were made differently. Those flat ones on the wall can be seen in any old wiring book and were on ebay new, and the ceiling type are NOS as later used for electric fence at one time.....Dave
You're amazing, more videos, and faster please.
I've just come across your series of videos, great stuff!
In the 50's I worked in a small shop that still had the line shaft overhead. Not used but just left there.
One question, maybe explained in a video, is why you always use 4 jaw chucks. Weren't self-centring scroll chucks around when your lathes were made?
Hi Colin, welcome to the channel. I just don't think you can do much with a 3 jaw chuck. Tom uses one for repetitious things, and hex stock....Dave
@@davidrichards5594 Thanks for answering. My working life was spent machining small stuff, mostly from round bar. Occasionally there would be some square bar and only then would I change to a 4 jaw. That one of yours looks like it weighs a ton! I'm enjoying every episode and see I have way more to look forward to watching. Thanks for taking the time to film, edit and post them.
I like cattail foundry ..ive bought steam fitting and oil from them
Great new intro Dave, well done.
Could you plumb that so the condensation goes back into the barrel? Or, just not enough water to worry about? I've heard good things about Catail. Liked.
Good question, that water (unlike the exhaust) could be recycled because there wouldn't be cylinder oil with it. I don't know if there will be enough to bother with, it would be mostly on start up, we will see.....Dave
Great to see the clock, I've been hearing it in other vids and was wondering if we would ever see it
Thanks for your videos Could you explain why putting a crown on the pulley helps the belt track instead of running off Also could you explain why the old timers would put a twist in the belt ( I know it reverses direction) when they didn't need to Did the twist help the belt track
A flat belt will "squirm" and run to the tight side of a pulley that is out of line. A crown puts the tight part in the middle, so the belt runs there. You can even create a crown in the center with a couple layers of tape wrapped around the pulley. It will really improve a flat pulley. Old timers ran long belts with a twist if the natural frequency of the belt length at the rpm they were running made the belt bounce up and down or oscillate across the pulley uncontrollably. The twist altered that critical frequency. ...Dave
