I really like that way of getting out of the error of the 'flat bit' of the sine wave at tdc and bdc. I'll try it with a rod through the plug hole on the next bike engine I need to mark up. cheers, Mark
Thanks for preserving and sharing this knowledge on RUclips, Dave! I'm 29 years old and love seeing all of this old technology in use. When I was a kid, my dad and grandfather would take my brother and me to a steam and gas engine show every summer here in southern Minnesota and I loved seeing all of the old equipment. It's nice to see that yours is still doing what it was built for, rather than just running for show! Steam power is fascinating. Some days I think we would be better off without all of this electronic stuff and computers and just use the old technology, but then we wouldn't get to see your shop! I check your channel every day to see if you've posted something new. Can't wait to see that behemoth plumbed for steam and running!
I'm a bit slow--Just noticed the "Richards Iron Works." I'm sure you noticed it straight-away. Awesome addition to your shop. Thanks for the great content.
The look on your face at the end of this video speaks volumes . . . you've got to be one 'happy pappy' with your namesake engine getting ready to push some tools ! 'Lookin forward to seeing this one go 'LIVE' ! !
I am fairly new to your channel David but have been binge watching since I found you and really enjoying your channel. Beautiful shop you've constructed and a collection of some of the world's greatest toys/tools ;-) Best Wishes and Thank-you so much for sharing.
I enjoyed seeing the timing process done. You have mentioned it several times in past videos. A simple very logical procedure. I hope to see the process for the concentric some time. Another very informative video.
Hi Dave, There are insufficient words available to express how tremendously interesting these past episodes have been. Your method of instructing/teaching makes each program most enjoyable. Eagerly looking forward to number 27 . By the way, have a 1919 5Hp Economy that we have run at the Burlington County Farm Fair for the past 50 years. Lawrence Cauffman, Mt. Laurel, NJ
Hey Dave, that is a very nice engine and was kept in great shape. Glad to see new video. Kept up the good work and practices of the early machine shops. God Bless Ya Dave
Thank you so much, you have a fabulous channel. I am certainly excited to see the engine running under steam. And watching you examine the old engine is very interesting. I have been a subscriber for quite some time and love the way you do things. You do have a great knowledge of history and respect for machinery. Thanks again. I would love to see you and Adam79 get together sometime, that would be great.
Bonjour David, I like your whistle very much ! Besides this, what I like with my little steam models is that they are exact replicas of your large machines. I can not wait to see your machine running ! Amicalement, Raphaël
Another great offering Dave. I have had 15" gauge locomotives jacked up on sleepers down the back of the shed running in on air a few times. We had a high volume former road works compressor, rail mounted, to do this job. The only thing I would add is over oil when running on air as the oil will not atomize. As for timing we were lucky as we had piston valves with viewing plugs driven by Walschaerts valve gear. All designed by that Master of the 15" gauge; Henry Greenley. Please keep this great works going, it is something to look forward to after the mundane that is prevalent on RUclips.....
By the way, I drove steam powered winches on old Liberty ships in San Pedro, CA back in the early sixties, most people just don't realize the power of steam, the old timers would say if you tied that cable to the dock it would turn the ship over & I'm sure they weren't kidding :-)
Great video. I wondered how they timed engines. If I remember my high school geometry set the divider a little bigger than half and scribe an arc from each mark. The arcs will cross at the mid point. Transfer it to the edge with a square. Well within the accuracy of chalk marks. ;-)
Man how nice it is to watch this steam engine work being done reminds me of the steam engines in the Tannery here in middlesbor ky.of long ago. It was my play ground,I used to trap muskrat and sell the hides all thru school years.I also worked in the tannery in the summer months.The Tannery had steam engines doing all kinds of work big and little,sump pumps,water pumps,so many other things.Just wonderiful to recall all of it.Thank You very much your friend steve shoemaker .....!
Hi Steve, You were lucky enough to have seen it, most factories like that just went away with no interior photos ever taken. There was a tannery a city block square in this town also in the mid 1800's It must have had a lot of steam because there was a huge tapered square brick stack shown in photos before being torn down in the 1920's.....Dave
David the boiler room had 4 big boilers each one was about the size of a train box car but not as tall.usualy one down for cleaning tubes 3 working.,the chimney was huge as best i can remember about 200 feet tall or so,and my dad was the super,so it was my play ground at night after running my trap lines,carry ed a colt 22.pistol with big dog his name was sunny the tannery was the largest in the states i think,alot more to this i would be typing for day's ............Your friend steve shoemaker
Mr. Shoemaker, If you have photographs of the old Tannery and if you're Dad is still alive start recording his memories of the tannery as history like old school factories should be preserved for the future. Then I really think you should write a book. Don't worry about not being an author as simply ask the local papers editor if he knows any editors willing to look over your written material with you as your not an English professor. And there is another option, an English teacher from high school. If the preview editor makes any corrections you disagree with you sit down with the original work and the editors corrections and detail why it's important to change her text. Must have been one helluva playground! Cheers
You have outdone yourself with this segment, absolutely the best lesson on timing a steam engine, I came home from work and there it was a notice you had posted a new clip, I just started to watch it and the wife called me to dinner, she said whats your rush as I was wolfing down my dinner and I said I got a great clip from Dave that I need to watch. I'll echo what everyone else says " best channel on you-tube"
I really do like this channel. I have learned so much about steam engines. I really am glad you share so much info on these machines. The new engine seems quite sound and what a find. Your teaching approach is great for novices Thank you so much!!
Very good video enjoyed it very much Nice to see the old iron being preserved for the next generation Who wouldn't know what it was if it wasn't for these videos and just scrap it
The start of this video brings back memories of the time wen I was a young boy. Our dairyplant started up with a whistel blow also. And sometime I was the one who pulled the cord. Thank you for making my day a good one. Greetings Henk
I wonder what it would have sounded like in this town in 1900. I'm sure the tannery, farm equipment factory, dairy plant and two saw mills blew at 12 noon every day and the town is in a valley.....Dave
Something that saves a lot of big engines, they're pretty much moving oil slicks. That engine is great shape. Man excited to see that new engine chuff along soon.
Thanks Dave, I am really learning a lot, I ran the threshing machine at our show for several years that we sometimes powered with steam, while I liked the sound of the engine I was always a little nerves being around them.
Dear Dave Another great steam related video. I think that is about the nicest, most succinct description of valve setting on a steam engine I have ever seen. Marvelous. Paul
Thank u for the vlogs Dave absolutely love thm I'm a 37yr old welder from Scotland and can't work now due to disability but due to ur videos giving me the inspiration to do smthing in my hut I'm ordering small machine lathe for the hut n can't wait to start doing sm odd jobs out there on mabe small motorcycle cylinders n things like tht and making diff things , keep up the gd work m8 n keep the videos cmn as long as u can 😊 aw the best fae ayrshire Scotland m8y
A lot of precision,to do it just right.The books help,but seein is believing.It's going to be a hoot when it's up and running.I can't wait till the next video.You,ve got the most exciting machinist channel on U tube.Thanks for all the hard work
Hi Dave. Your videos really look great. I've really learned a lot watching your channel and enjoyed ever minute of it. I guess it might be boring to real machinists but I'd like to see a bit of a tutorial about grinding cutting tools. Just those few moments of you grinding a drill bit a few episodes back helped me a lot. Thanks!
Hi Dave, from far Germany I'm watching your Videos with great interest. As a mechanical engineer with some experience in timing steam locomotive valve gears I want to suggest you to put the slide valve a little bit out of the middle in the direction of the fly wheel, when you are timing a cold engine. This will consider the changing of lengh of the valve rod due to the thermic extension. Using scratch marks instead of chalk will improve the accuracy as well. Using the same direction of turning will eliminate most of the play from bearings and connections.Kind regards from Dresden Sven
Dave I love your workshop, in fact rather envious. I know this will sound off the wall can we see your clock it keeps tick tocking so reliably somehow rather reassuring like these old reliable machines
Excellent stuff, Dave. Thanks for sharing your knowledge and experience with the wider world. I'll be going to the Sycamore steam show here in a couple of weeks ( Illinois ) so I'll get my yearly dose of old iron. It's amazing how little wear there seems to be in your engine. You got lucky and got a good one there. Regards, Jeff
Proper job thanks for the info, having a go at making small engines and your information will help me. Love the engine you are working on, looking farward to see it running.
G'day the intro's are very pro to the ones when you first aired on RUclips and they look great. It was a very interesting video especially the valve timing. The engine is certainly looking great to when you first got it. Looking forward to the next one regards John
Really enjoyed watching it, it's fantastic to see, I'm looking for a clock to my shop I really got to have one, tik tak tik tak I love it. For a while ago you talked about making your own electric power from steam, I have watched at your old electric Installation it's really fantastic, it's almost like it says, "I want my power from steam" Thank you for the videos😊
Good job on the video you know you'll have to come to the summer bash to meet every one your more than qualified to come and more than welcome in my book
Nice to see these old engines being worked on. Having played with steam engines I never bothered to find top dead centre if you are not adjusting the eccentrics. If I remember correctly, I just made sure the maximum inlet exposure from the outer edge of the port was the same on both strokes.
I love to watch the work you do on the old steam engines. I like the old throttle control engines, also! So if you do more work on hit and miss or throttle governed engines I'll be right there God permitting. Looking forward to any videos made from your shop(s). Greg
Well let's see....I use race gear oil for the babbitt line shaft bearings, medium weight "way" oil for everything on the machines, left over Aeroshell straight mineral aircraft motor oil for drilling and tapping (because I want to get rid of it), lower grade "green velvet" steam cylinder oil in the displacement lubricator of the small shop engine, and regular (or as close as you can get these days) steam cylinder oil in the big engine oil pump.....Dave
1/2"-12 is standard Whitworth thread. Most inch size taps or dies not specifically marked UNC is probably Whitworth. Quite common, but out of date today.
SLORRIFJART321 Whitworth is quite a well designed system, I still have some Whitworth spanners which are not marked for the nut size in inches but the thread so 1/4 whit is rather larger than you might think - it is all to do with ratios and the appropriate torque -
I remember from mechanical drawing to find the exact center of a line regardless of length, open your compass/dividers past the center. Starting at one end point strike an arc and do the same from the other end point. Where the two arcs meet above and below the line, draw a vertical line through them and that will always be center.
That is a very nice looking engine. I saw it running on air too. It definitely is not a balanced valve engine. A quick and accurate way of marking TDC & BDC is to use the dividers and make two crossing arcs on the face of the flywheel from the marks first made with two different radii then using a straight edge across the two sets of arcs to the edge of the flywheel. I was thinking of using feeler gauges to measure the valve gaps. The eccentric should be keyed to the shaft. IF the eccentric were taken off and turned around the engine would run in the opposite direction.
Hmm, I'm wondering now, once you get the big engine up and running, would you be able to possibly convert the large boring mill over to run on the line shaft? I dare say you'll have plenty of power. :)
I'm ok thanks Dave. Year started out well, but then the tractor decided to break a valve. So since then all I seem to have done is work on it. Got it done enough for now. Next show is this weekend, taking it on truck so should make the showring this time (grin).
Dave, I truly appreciate what you're doing. Have a question. I'm in the process of building an off grid cabin for retirement. Wood fuel is abundant, and I would like to (in addition to solar) generate power with steam. Thoughts? Hints? Opinions?
Thankyou ,really enjoyable,thanks.
I really like that way of getting out of the error of the 'flat bit' of the sine wave at tdc and bdc. I'll try it with a rod through the plug hole on the next bike engine I need to mark up. cheers, Mark
Thanks Mark, all you need is a 'stop" of some kind screwed in the plug hole....Dave

Thanks Stephen, good to hear from Malta....Dave
Thanks David for another great video. Mike
I am up to 26 now on the full channel watch . Love every min of it !
Thanks guys, a lot here, and I enjoyed it all. You timed that engine like it had combustion.looking forward to seeing it run..
good one. keep sending them. I hope to get steam engine some day. I have big bucket list. thanks for the show

I've always timed the steam chest by trial and error, your way is a lot faster. Thanks for sharing.
Keep that clock ticking All the very best peter
Love your shop, Dave. Thanks for sharing it with us.
thanks for sharing your knowledge with us Dave very interesting video I was always fascinated by Steam such an economical resource of energy
Not necessarily resource economy; but resource availability. ie. wood and water.
i think there only about 30%
What else did they have?
Internal combustion at the turn of the century using the byproduct of kerosene production.
Dear Dave
Another great steam related video. I think that is about the nicest, most succinct description of valve setting on a steam engine I have ever seen. Marvelous.

Looking great Dave.
Thanks for another high quality video. Looking forward to seeing Richards' Richards running.
I'm just glad there is another show.
Thank you.
real clear video That's going to be a powerful steam motor can wait to see her under steam all the best from John in Texas

Wonderful, just wonderful.

GREAT JOB. THANKS FOR SHARING.
Better all the time! Thanks, Dave!
very informative great old school .
Good idea using divider to make fly wheel. Much more accurate than a tape measure.

Love your videos !!! You have the best video intro segments on you tube
I really enjoy your videos, so thank you for sharing! Your video lead in with the steam whistle blowing and the music you chose are perfect! great job
Dave:
Thanks again - it's so cool to learn about adjusting a steam engine - where else would we learn this stuff?
Too much fun...
J.
Nice to see these old engines being worked on. Having played with steam engines I never bothered to find top dead centre if you are not adjusting the eccentrics. If I remember correctly, I just made sure the maximum inlet exposure from the outer edge of the port was the same on both strokes.
I love to watch the work you do on the old steam engines. I like the old throttle control engines, also! So if you do more work on hit and miss or throttle governed engines I'll be right there God permitting. Looking forward to any videos made from your shop(s). Greg
are you going to leave the original set-up in place, just in case you need it as a back up?
Hi Merle, Probably a good idea until it's been run awhile...Dave
What oils and grease do you find unsfull in your shop? Thanks for a most interesting show.
Well let's see....I use race gear oil for the babbitt line shaft bearings, medium weight "way" oil for everything on the machines, left over Aeroshell straight mineral aircraft motor oil for drilling and tapping (because I want to get rid of it), lower grade "green velvet" steam cylinder oil in the displacement lubricator of the small shop engine, and regular (or as close as you can get these days) steam cylinder oil in the big engine oil pump.....Dave
Thank you
1/2"-12 is standard Whitworth thread. Most inch size taps or dies not specifically marked UNC is probably Whitworth. Quite common, but out of date today.
I forgot all about the old Whitworth. Thanks
SLORRIFJART321 Whitworth is quite a well designed system, I still have some Whitworth spanners which are not marked for the nut size in inches but the thread so 1/4 whit is rather larger than you might think - it is all to do with ratios and the appropriate torque -
I had Whitworth sockets for my Triumph.
Can't wait to hear that engine on steam.
Dave your videos are great. Keep up the good work, I always look forward to the next one.
Always great videos!
as always...great video !
We need moar of them !!
Moar! Better!
Toodles!

I remember from mechanical drawing to find the exact center of a line regardless of length, open your compass/dividers past the center. Starting at one end point strike an arc and do the same from the other end point. Where the two arcs meet above and below the line, draw a vertical line through them and that will always be center.
That's a good way if you have enough width to get a good size arc.....Dave
mate the videos are getting better and better each one keep it up mate
Nice bearing serfaces there.
That is a very nice looking engine. I saw it running on air too. It definitely is not a balanced valve engine.
A quick and accurate way of marking TDC & BDC is to use the dividers and make two crossing arcs on the face of the flywheel from the marks first made with two different radii then using a straight edge across the two sets of arcs to the edge of the flywheel.
I was thinking of using feeler gauges to measure the valve gaps.
The eccentric should be keyed to the shaft. IF the eccentric were taken off and turned around the engine would run in the opposite direction.
all true Roy....Dave
Hmm, I'm wondering now, once you get the big engine up and running, would you be able to possibly convert the large boring mill over to run on the line shaft? I dare say you'll have plenty of power. :)
Excellent
Your videos keep getting better Dave, if that's possible :) That engine is sure in great shape given it's age.
Thanks Malc, what's up with you these days?.....dave
I'm ok thanks Dave. Year started out well, but then the tractor decided to break a valve. So since then all I seem to have done is work on it. Got it done enough for now. Next show is this weekend, taking it on truck so should make the showring this time (grin).
If the slide valve had a groove in the face, could you resurface it with your metal shaper machine or would making an interrupted cut not work?
Dave, I truly appreciate what you're doing. Have a question. I'm in the process of building an off grid cabin for retirement. Wood fuel is abundant, and I would like to (in addition to solar) generate power with steam. Thoughts? Hints? Opinions?
Yeah! Dave's back!
