- To supply Compressed Air for Model Steam Engines on the bench I would normally use thick walled Silicone Rubber Tubing. But this is dangerous when used at higher pressures. In this video I show some simple and more sensible alternatives. / keithappleton

Good health to you.
We expect many more years of interesting and amusing tutorials to come.
I hope so - Happy 2024 }:-)))
I wish you all the best for 2024 Keith. Be like the British Cycle team and go for the many small wins approach. Eat healthy, be active and try to recognise the little things that make you happy and celebrate them. Don't stress on what is out of your control and make that stop you doing your thing/the best for you. Big (work safe) love 😽
Happy 2024 }:-)))
Very close to my personal philosophy. Happy New Year }:-)))
These characters that give you grief over the use of adjustable spanners need to work in one of the factories I used to work at.
The engineering stores purchasing officer was a miser and he would buy fasteners based on how cheap they were rather than buying standard sizes. It was possible while working on a machine to come across bolts of the same thread size that had up to four different head sizes, some non-standard.
It made using adjustable spanners almost compulsory not an exception.
Realistically there was no problem with it as long as like you say use a quality spanner and adjust it correctly.
Love your humour and videos. Hoping all goes well with your prostate Keith.❤
Thank You }:-)))
A doctor of mine said that more men (who have it) will die WITH prostate cancer rather than die OF prostate cancer. If yours is described as "low grade" it is not a cause for concern. It can't be ignored but there is no rush either.
Mine was described as "small but hot" and needed comparatively prompt attention. Even so it was nearly six months before it was properly attacked with a combination of surgery and beam radiation. So far the result seems to be good.
Have great New Year and we (your audience and patrons) look froward to more in the future.
Happy New Year to you also Jeff }:-)))
To expand on what Jeff said, if a human male lives long enough, he WILL develop prostate cancer and something else will cause his demise.
Wishing you health and a happy new year
Happy 2024 }:-)))
Sorry to hear about your health issues. I’m not sure what to say except I’m hoping for the best.
Happy New Year!
Same to you! }:-)))
Great Job on the machining. It looks like a lot of fun. Stay safe and super healthy yourself also!
Thanks Paul, Happy New Year }:-)))
Light and easy video idea. People who complain about the adjustable wrenches. They really dont get how small all of the fasteners you are using are. You couldnt mar up the hex before breaking the bolt. Perhaps a comparison between model engineering sizes and measurements in metric and imperial. The bolts you are tightening are so tiny and often brass. The smallest thing we would use is 1/4 national coarse thread and it would be steel. If you found a table of strength of a 7BA stainless bolt and a 1/4 bolt grade 2 (which is garbage) it might give some perspective.
Keith if you use hose that have a brad string cover that are better if the rubber hose inside pops
I would agree. I am going to buy some more air hose a bit thinner and more flexible.
I see your friend andrew, had issues with his Stuart no’7 , i thought i spotted a CNC lathe in his shop that explains his four cylinder engines accuracy. I fail to understand Keith how he could have errored with the Eccentrics. Why would stuart offset those bolts on the side of the steam chest? I noted in the video that the cylinder cover was to small but i could not determine this simply by the video. I guess he is not very good with manual milling i saw his four cylinder aluminum engine obviously CNC for that kind of perfection well happy new year. My wife and i might be going to the south atlantic region soon.
Happy New Year Keith:
No CNC - just a couple of DRO units (on the Milling Machine and Lathe). Andrew has not been model engineering for long and is therefore inexperienced in certain areas..
@@keithappleton Thank you Keith for your reply. I noted that you mentioned your health again as “Low Grade” usually Doctor’s don’t mess with cancer in those area of men, but if he says low grade your a lucky camper. Its 7 am here in Ottawa Ontario Canada. My wife just found out yesterday her father as multi cancer tumers in his spinal cord. I am having a hard time leveling my new lathe, its the floor of our house thats the problem. I should get it right on today. I was thinking of your knee pad idea, if i can’t level it today i will do what you did with your Warco “Knee Pads” maybe a few for my bad knee’s as well. I cannot understand how Andrew could error with the seven yet his four cylinder looks great accurate. Learning for some takes longer then others i guess , i am sure i will make worse errors then Andrew, i won’t show you them as you will pull out a sludge hammer instead of a small hammer.
The problem i am having is that i have drawings in cold rolled steel , i understand most of the drawings as i spent years studying them , they are not easy to understand because of some side notations are not quite clear enough. On another note regarding my new lathe, their is one draw back, as the manufacture replied finally, i cannot fit my new four jaw independant chuck to the spindle back plate , nor can i remove the back plate for the three jaw, the manufacture states i must make a new back plate and fit it over the three jaw back plate on the spindle then mount the four jaw. The problem is this two fold , the manufacture did not drill extra holes for an optional four jaw and you cannot remove the current back plate from the spindle, the 125 mm three jaw with the unit only has three holes not four, maybe i should tape the four jaw on with “Duck Tape” . Today once i level the lathe if possible , next i will check the run out on the lathes three jaw chuck and spindle, i know i am blessed if under one thou of run out. I will stop here send this to you and write one more here, no need to reply Keith i know your busy.
@@keithappleton Hi again Keith i have spent or will have spent 4000.00$ or so with Amazon buying all i need for building steam engines. I will be having another 8000.00$ deposited soon. I do intent on buying some units from Stuart for SURE i think a couple of D10’s and a twin and a gift for you as you made me a model engineer with out your video’s i honestly would have been lost in outer space, if not for your beginner series all though based upon Stuart castings the rules are the same. I sent Stuart a email just before christmas but have not received a response as yet. I am going to build a unit off of the plans i have to gain experience before i attempt my Stuart d10 as the castings are expensive here a d10 casting set in canadian dollars is about four hundred $ plus 50 pounds stirling for shipping over seas. Regarding cold rolled steel , i was going to use 12 L 14 which is a lead based steel for the cylinder’s and standards but in the case of the drawings i have the author calls out for the standard to be welded to the lower cylinder base plate, further 12 L 14 is known to rust because of the lead content further 12 L 14 is also exspensive cast iron is out of the question it is really exspensive. Cold rolled is good but also very hard, it takes a long time to cut it with light cuts only. i will use 12 L in non critical areas. I am going to buy a second lathe as well a bigger one, either a busy bee craftex 10 by 22 or a King Canada 10 by 22 i want two lathes. My milling machine is a small one 350 watt with a three inch wide by 12 inch table the fine feed knob is useless, i have to turn the knob a half inch before i get a reading, i was going to take it apart as another guy had the same problem with his, it turned out the slop was in the worm gear that drives the fine feed knob. i will indicate this , although a bottom line mill it has a lot of power and i can run a 5/8 four fluked carbide cutter in it no problem, i made a error though, i bought a four inch milling vice for it its way to big i am in the process of returning it to amazon i will buy the three inch when i return it and get my refund along many many other refunds?! I bought a rotary table three years ago but did not have chick or back plate, so i bought a 80 mm three jaw it arrived the other day from India, the jaws where infact stuck in it tight so tight i needed a strong arm to get them out i was concerned i was damaging the jaw slots but they are ok i will have to slighty carefully file out the slots and jaws carefully with a small file until i get a good sliding fit, i want to drill out the cylinder holes and cylinder covers with the rotary table. Quite often i see that we all order brand new stuff and the maufactures like to make errors so that we can correct them. All the stuff i bought and my second list already prepared i have ordered all of it based upon what you use. I also am taking in this Iphone soon to a priest to have a exercisum done on it it seems possessed. “No kidding”?! Finally i must say that this new lathe a WM 210 V is very impressive accurate right out of the box “shocking” its got a 9 watt motor as well and i don’t need a crane to lift it on the table, the crane is coming with the next bigger lathe, i am going to tell the landlord he will have to buy jacks to hold up my floor once i get the bigger lathe in. I am going to use digital calipers for the lathes dro one mounted on the tailstock one mounted on the saddle for the cross slide another for the lead screw travel i prefer these cheaper methods rather then a big box that kooks like it came out of the US space shuttle program, the lathe dro is miner since i can simply use the dials and a micrometer as u use with light cuts. Frankly its the up and down travel of my milling machine that has messed me up a few times because i cannot use the fine feed dial so iam going to try and mount a 12 inch digital caliper to it on the side how i am not sure and i am not sure if a 12 inch electronic caliper will be long enough i will make brackets out of aluminum . Well thats enough now Keith i don’t want tou reading my long naratives all day long. I will try to take some pictures of my lathe and workshop and send them to you my iphone camera is possessed as well. Finally listen Keith my friend, don’t mess with this cancer and don’t let doctors delay demand it get taken care of real fast, my father in law found out he has 1 month to a year left and thats provided the radiation has some effect he is in-oprable he is 87 or 88 i am not sure. Again happy new year Keith. Regards Daniel from Ottawa:
Keith, that "type" (I'm not sure that's the correct term here) of threads are you using? I've found 3/8-32UNEF and also 1/4-40 pipe threads, but they're not in the same "Standard." Are you using some kind of special "Model Engineering" threads instead? Or something else?
I am using ME threads.
@@keithappleton Thanks Keith. Now everything about your threads makes more sense to me!
