WHAT IS IT?

[@markl2761]

Mr. Pete Proverbs. 19:20 Tell us to listen to advise and accept instruction, that we may gain wisdom in the future. I for one thank you for your wisdom in these matters. I have learned an abundance of information by listening to you, and am wiser for it. you just keep on talking and I will keep on listening. Thank you.

[@johnjohn-ed9qt]

Engine indicators go back to the 1800's, and were first used with steam engines. The output is pressure vs. piston position, which can be correlated to pressure vs. cylinder volume. Ashcroft made them (the one I have used), as well as matching planimeters for measuring the area on the indicator card (which gives the energy per cycle, which can be used to determine power and efficiency). Large engines often have test ports available for each cylinder. Attaching the string to get true measure of the position can be an interesting exercise on some engines. Also Crosby, and a number of others. A LOT of precision tools were made in DDR back in the day. East Germany had the skilled people and help reconstructing that Russia didn't have after WWII, and micrometers, indicators, calipers, gauges,etc were made there and filtered throughout the soviet controlled states.

[@hellrocker1212]

Im 22, I love sittign and listing to long videos about things like this and tools, how they were made and used. The longer the video the more i can learn. The guy who said you like to drone on is just not willing to listen and learn, i am. I and many others would love more videos that are longer and go into great depth and technical information.

[@MichaelDisney]

I could listen to you all day Mr Pete - and I have done several times in trying to catch up on all your videos! Please keep them coming though and thanks for "edutaining" KZbin.

You have a great deal of knowledge. You speak, we listen and learn.

[@remige2006]

Speaking about small holes... Very interesting this explanation related to the way the diameter of a hole was incrased by pressurising into it an abrasive liquid... as much as it was interesting to understand that tiny holes were drilled by EDM.... Mr. Pete, what is the smallest drill you have seen ? Most of the charts stop at number 80 drill. Harvey's tools is selling a german made one wearing the number 102 ( about 0.003 "). It has a large hexagonal shank ( about 1/8 ") and cost around $50.00... Teachers like you are a real gold mine......

[@TheQwik512]

You are a teacher, your voice is a primary tool of your trade. I would venture to say the vast majority of your subscribers enjoy your verbose style, the naysayers can take a long walk off a short pier or simply quit watching your content.

Mr. Peterson,If you didn't take the time to talk to us,I for one would probably not be a subscriber to your channel. I don't know about everyone else but,I like knowing as much about a subject as I can. You feel free to get as in depth as you feel is necessary,on any subject you want... I WILL BE WATCHING!! (And learning) Thank you sir.

[@Midwest-FieldOps]

I personally dislike instructional videos without commentary. This is possibly the best channel on KZbin. Keep up the commentary!

[@p4_nz]

Thanks for featuring my present, mr. Peterson! I've asked a few people that were somehow related to marine engine repair, since I live in a seaport. They all said that these indicators are used frequently and everyone just calls them "Maihak", never knowing why they're called such a name. This particular iindicator is a lot older than the others that I've seen.

[@mrpete222]

Thanks again--Many people liked the video. I was urprised how many correct guesses I got.

[@bobparry4575]

I work at an University and we have one of these attached to our extremely old Natural Gas engine that we use to show students how engines work. Ours is a single cylinder engine with exposed valve train and open crankshaft spinning a large flywheel. This instrument is connected to the cylinder head and the string you see is hooked onto the crankshaft. This will then produce cylinder pressure vs crank angle diagram. This is very useful for teaching and I can see how it would be used to tune and test engines.

[@mrpete222]

I'd like to see that

[@bobparry4575]

I will get a photo for you and send it to you.

[@jcs6347]

Hi Lyle, DDR is the old East Germany. I didn't read the other posts, so I hope i am not repeating anything. I was stationed on the W.German/ E.German border when it came down. Thanks again for the video!

[@bradmcconnochie3204]

Greetings Mr Pete, Very true, the indicator attaches to the "indicator cock" on the head of each cylinder. Using the spring constant (amount of pressure it takes to move a certain distance) the average area under the resulting line, and the length of the graph, the mean effective pressure can be obtained. indicated power, rather than brake power, can be found by multiplying the pressure, stroke, bore area, number of cylinders and rev's per second. This is for a two stroke, with a four stroke this number is halved. What makes this interesting is we now have digital versions that take a tenth of the time and store ask the data, and pressure sensors, so we can see from the control room what the engine is doing and make adjustments in real time. Thanks for all the great videos. Best regards, Brad

[@bradmcconnochie3204]

All the data, not ask

[@flixtonman]

HI Mr Pete when I was a apprentice motor mechanic at technical college we had a National gas stationary engine with one of those indicators on it ,and we all took it in turn to run the engine with the sensitive paper in the drum this was to explain the power curve of the engine the graph produced is like two bananas one upright and the other lying down ,I still have it somewhere great video ass always . dave in the uk

[@johnhollyfield6557]

I like the discussions / descriptions that you do. As a teacher myself; you need to be able to succinctly describe something that can be very abstract to students / novices. You do that very well. To further increase the understanding; You even go farther with the teaching aids that that you create, design, build, construct and then demonstrate. I wish I had the pleasure to have you as my Metal Shop teacher. Mr. Pete you are awesome. Keep up the good work. Stay healthy my friend. John H

[@mrpete222]

Thanks very much--good to hear from another teacher

[@icarus901]

And because teachers aren't thanked nearly enough, thanks to both of you. Mr. Pete, pay no heed to the detractors. You don't overdo it/talk too much. We're here because we appreciate what you share and how you do so.

[@geoffwood9972]

My apologies for the lateness of my post but have only now seen the video. The item is an Engine Indicator which is used for calculating the Indicated Horse Power being developed by (in this case) a large diesel engine, they were also used for calculating the I.H.P. being developed by Steam Engines. To calculate the I.H.P. being developed by the engine the area of the of the 'banana' shaped trace (indicator diagram) produced on the paper slip wrapped around the cylinder had to be obtained, this was done using an instrument called a Planimeter. As an apprentice marine engineer in the early 60's I took many of these indicator diagrams from a large marine triple expansion double acting engine to log the I.H.P. it was producing - this engine eventually found its way into the foyer of the Science Museum, South Kensington, London.

[@geoffwood9972]

I forgot to add that it was a Marine Steam Engine

[@tedfarwell9812]

Talk as much as you want; you always say something worth listening to. Your videos are always the right length. The pressure-stroke area described by the indicator was a way to determine power output; i.e., "indicated horsepower". Thanks for another great video!

[@MrArray1967]

I might be way too late, and well then it's not the first time. I know what this is. In Danish it's called an indicator which measures the pressure in the cylinder of a (two stroke) combustion engine (maybe also a steam engine) as a function of the crank shaft angle and draws an indicator diagram. With an area planimeter the mean indicated pressure in the cylinder can be calculated (indicated) by means of the diagram. Different kinds of diagrams can be produced. Combustion pressure, compression pressure, charge pressure, exhaust pressure etc. can be established.

[@matthewparker1359]

I get excited when I am notified of a new mrpete video. I can hardly wait to watch it. Keep doing what you are doing and the way you are doing it. You give new meaning to the old saying "learn something new everyday". 👍🏻

[@drjwrg]

The indicator device is used in calculating the efficiency of an engine it allows Indicated Horse Power to be calculated and that can be compared with Shaft Horse Power to calculated engine efficiency.

[@boelwerkr]

Now i can write my comment about the pressure indicator. ;-) The title of the label has to be read like that: --------------- Produced in commision of the *Metallwerker KG* ( Metall worker community incorporation ) by *Hugo Voss & Co* (the manufacturer) in *Meerane* (the town) in the *DDR* Spring-table for the indicator Type 30 and Type 30/H ---------------- Metallwerker KG : Joinment of all mashineproducing industries in the DDR "Hugo Voss & Co" a known manufacturer of precision measurement tools in germany from ~1920 to ~1945.

[@PeopleAlreadyDidThis]

You just talk on, Mr. Pete. Those who exist 140 characters at a time in a shallow world of tweets can be pretty impatient. They do have options other than complaining: (1) turn off the speakers and guess what's happening, (2) close the video, (3) turn off the computer/phone and go meet a real person. A student once wrote me up for going "off task" in class...never did catch the connection when it came along later. Now, I have to admit, I have shut down some videos because I ran out of patience with lengthy, undirected rambling. Some can speak extensively and never say anything. Yet I never stop a Tubalcain video, no matter how far afield it goes. Your classroom and work experience make your delivery lively and interesting. Today, I stopped for some pretty bad pizza after tearing into a bad gearbox. Watched this video while eating. Same as having lunch with a friend. Good conversation, bad food...and now you need to teach me how to single-point a worm wheel on the Bridgeport! Your subscriptions have risen 2.5% since the recent 100,000 milestone, so complainers aren't the focus. Wish my investments were doing that well.

It is conventional KZbin wisdom that the majority of people like videos under 5 minutes long that do not require deep thought.
