I have a full size steam engine 8 inch bore and a 10 inch stoke, similar to your model, I run it with a 40 HP Case steam boiler, it is lubricated with one of the steam condensing water lubricates you are talking about, they use a special steam oil also the cylinder is lubricated with graphite. I enjoy your RU-vid episodes, you are a good teacher.

You are correct about the ratio of mass and weight to the size of the drill bit. Considering the size of that assembly and weight of the angle plate your did just fine. I would not have done it much differently. Problem is far too many of the people criticizing you are armchair quarterbacks. I took my training as a tool and die maker in 1972 and if it means anything to you, I like the way you work. I am retired now and I have discovered you tube. I like your videos. I am going to order that large steam engine you have recently started. Have fun and stay safe.

@augustvonmackensen9785 3 года назад

Also, running your engine on compressed air is very different from running it on live steam. If you make your engine too precise, heat will make parts expand and the engine will stop, it is really a very fine line between having it run smoothly and not running at all. I built a few engines, I have no idea why I keep going back to making small intricate parts for tiny machines, it is time consuming, frustrating at times, but it is highly satisfying to see them run at the end.

@pauls5745 3 года назад

yes, I hadn't thought of how clearances will change with hot steam compared to air power. the PM 1 really is deserving of a boiler

@derekschipper8721 3 года назад

Making your engine too precise is not the problem. Think about how silly that statement sounds. The problem was the intended design; perhaps the intended clearances/fits should have been loosened to account for expansion of materials under normal operation. If you backed something off by .003, your new "target" dimension is what you aim for, and you want to hit that dimension as accurately / precisely as possible.

@jimsvideos7201 3 года назад

Have you ever used a Noxon punch? It's a short prick punch butted up against a short center punch with a tension spring between them. You pull on the one end and the spring drives the other end into the work. They have great feel for lighter marks and enough wallop for deeper ones.

@gregranbo9113 3 года назад

Make a drill guide for your holes. A round blank or square then drill your pattern thru it with all the holes, the big bolt pattern and the small holes, and leave a boss in the center to locate on the casting unless you have the right size pin to locate the center hole. I never use punch marks for close tolerance holes. maybe for an oil pan. Just a different way of doing it. Try a 3 fluted end mill for slots. All I use now is 3 flutes or 5 flutes or 1 flute. Keep it odd Blondi.

I'm also happy to see many old steam locomotives restored and brought back to life. The best one yet is the Union Pacific 'Big Boy' #4014 one of the largest steam locomotives ever built

Funny story, I bought I lot of tools from a retiring machinist and found a bunch of those "transfer" screws in his box in a wide variety of diameters and thread pitches. Coming from a fixture design and build background I thought they were just a niffy way to keep around set screws for when you needed. But, now thanks to Quinn I know what they are actually meant for (and the more I think of it, the more it makes sense why they are used in that manner.)

@steveallen8987 3 года назад

Love your work and particularly that you you let us know when your human infallibility strikes. It makes us feel not so stupid. But I did notice that when you mounted the cylinder with the transfer screws to mark the hole positions, you had the valve chest hanging out the opposite side to that which you chose to finally fit, that’s why you had to loosen up the clearance holes. (7:26) ( right hand side looking from cylinder down to crank and you are mounting left side looking down to crank. ) I spend a lot of time marking up castings with dyfken blue to indicate features, orientations, alignments, pairings etc as well as for marking out. More importantly for anyone running a steam engine on compressed air, you can buy inline air supply lubricators for old style air tools that needed oil mixed in with the air supply. Just search air tool oiler. They are cheap and replace the displacement lubricator when using compressed air and not steam. A MUST HAVE. Steve

Hi Quinn, Great video, I always look forward to your installments and have been following along on the steam engine build since the start of it. You do excellent work, your machining skills are a credit to you, again well done. I felt a need to comment on your channel about your comments on the transition of steam locomotives to Diesel Electric Locomotives, as I felt they were not quite correct. It is true, the 1940's modern steam locomotive was at its pinnacle of its development, and those large articulated steam locomotives packed some serious horsepower, 5000 HP+. As developed as they were, they were never more efficient than a Diesel Electric Locomotive. A modern steam locomotive required large amounts of maintenance, but their largest downfall was their inability to operate over large distances. If a train was to operate from Chicago to Los Angles (A distance of 2200 miles) it required the steam locomotive to be exchanged nearly every 250 miles as at that point it was nearly out of coal and water, fresh engines were installed and the train continued. In 1934 when the Santa Fe introduced their new train the Super Chief, they for the first time in the history of the world used Diesel Electric Locomotives to haul the train. They were able to shave off the schedule 15 1/2 hours, which was largely made up from the elimination of exchanging steam engines. The Diesel Electric locomotives were able to complete the journey non stop, they received fuel from fuel bins in the leading baggage car of the train. Diesel Electric technology had been developing since the 1890's in the United states and it all came together in 1934 from that point steam traction was finished it was to enjoy an Indian summer throughout the war years. The railways the world over had been in search of that technology since 1927. Once again Quinn, love your videos and keep up the great work. Regards, A Fan from Aus..

@QuaintonSteamWorks 3 года назад

The eccentric and slide valve configuration is actually really common on full size steam locos :) Where it gets more complicated is having two eccentrics - one forward, one reverse - and a method of combining and graduating the resulting motion between the two with an expansion link. We're overhauling a full size locomotive at the moment, the components of which look almost exactly like what you're building. Happy to send you some footage/pictures to show your viewers for comparison if you like?

@@nicholashacking381 My opinion is that there is no competition to see who’s “best”! It’s also my opinion that pie was WAY out of line to make belittling/disparaging/rude comments! It sounds like classic case of the high school bully who feels threatened. I’m a Blondie Hacker for life!

@@tomt9543 Agreed, I stopped watching him because of it. He always sort of rubbed me the wrong way with his arrogant attitude, but I watched anyway because he clearly has expertise and I could learn a lot from him. But once he started with the condescending and snide remarks it really soured my towards him. Like seriously dude, grow up and stop acting like a child.
