Today I went to Enstone airfield to a Bi annual bring and buy primarily to shift some stuff and look for some parts for the restoration of some of my Stationary Engines, I collect Lister's and am always looking for bits.

Came home with a few bob and a campingstove to add to my collection, this one makes it 131.

Gary and Andy,

Gentlemen may I suggest another museum called Internal Fire which is based in a village called Tan y Groes, it also has a very fine collection of very large internal combustion engines and is open from Wednesday till Sunday, I will admit to being a little biased as I volunteer there two to three times a year, have just spent the Easter weekend there, the museum has the largest collection of Allen Diesels of Bedford in the country go to this **LINK**

MichaelG,

Thanks for that, interesting data regarding the hole sizes as well.

Keith,

I'm injecting Liraglutide not Insulin.

Gentlemen,

I am type 2 Diabetic and recently I've been having difficulties controlling my sugar levels and the Doctors have now got me, since yesterday, injecting a drug into myself. The practitioner nurse instructed me in the use of what's best described as a pen.

As a working engineer I'm fascinated with this device for two reasons, the first is how do they make a 0.25 mm OD tube i.e. the needle and my second thought is there must be a use for the pen when the drug is finished. Its about the size of a large pen which at one end you can fit the disposable needle and at the other end is a dial which is adjustable from zero to 1.8mg in increments of 0.6mg and also a small pump to inject the liquid through the needle.

My initial idea is a lubricating device for small amounts, what thoughts have you.

Swarf,

I think not but this link **LINK** may clarify, I've still got my EITB paperwork from when I was an apprentice but thats now forty one summers ago.

Our apprentices do similar tasks but they are under a different umbrella.

Swarf,

Engineering Industry Training Board, many hits on Google.

Gentlemen,

Just as a slight aside I used to work for a company that sold machine tools from all over the world, one of our products was conveyor systems used on assembly production lines and we built a race track conveyor for testing a well known british manufactured mains powered electric drill after assembly. I found out whilst installing the equipment that your average DIY mains drill only had a life of twenty four hours, this doesnt seem a lot of time but when you consider what the drill would be used for, drilling holes etc which only take a few seconds, then the drill will last a long time.

Sandy,

Your Nephew should not be treated any differently because of his problem, he obviously has no difficulties with his hands otherwise he would not be in his third season with his current job, a testimonial from his current employers would also help him gain an apprenticeship place.

In the school I attended in the 60's, the Silver Jubilee Boys School Bury st Edmunds, we had a fully equiped metal workshop and wood working shop with permanent teachers, we also had a Technical drawing classroom, my grandfather was a model engineer and my father a draughtsman so it could be said that my brother and I were born into engineering. We both did our apprenticeships at a Lucas CAV factory and have both been in engineering ever since. We both have our own workshops and we both have hobbies that rquire the use of lathes and mills. I enjoy showing our apprentices the tricks of the trade. Their apprenticeships are vastly different to the ways we were taught because its no longer carried out in house, some is done at a local college, some is done with us and the rest is done through a teaching business.

Gentlemen,

the company I work for has taken on three apprentices, in the last couple of years, to work along side us service Engineers, they go to college on day release and then spend the rest of the week out and about with the engineers learning about our products and whats involved with Service, installation and breakdown repairs in both mechanical engineering, pneumatics, pumps, electrical and electronics which they also do at college. They also learn how to use machine tools.

Our MD recognises the fact that his service dept is made up of men over 55 who need to be replaced when they retire, I'm in that catagory, and what better way for the lads to learn of us oldies.

Martin P

Otley,

Thank you for that, I know have to tell my friend he was correct

Martin Perman

Otley,

My friend and I were discussing this subject at the weekend and watching video's as to how this works as I couldnt see or understand what happens, any chance you could explain it please.

Martin Perman

Yesterday I went to North Norfolk to see a friend and we spent the day at the NNR Gala weekend playing with trains we then spent some of the evening in his workshop discussing his latest project, a 0-4-0 Romulus which he is building as an 0-6-0 with other modifications involving the valve motion. Today I went back to the NNR for a few more hours of photography and then a 2.5 hr drive home.

Billy,

Every few months should read on average six months, the roller pressure is fixed and the tube is 2mm thick and we pump disolved salts, we also really on the customer keeping the tanks with the dosing solution topped up which means they can run dry which can cause the tube to stick internallly together. The longest a tube has lasted is nine months.

I still think that the use Bob wants to use it for will not be adequate.

Martin P

Bob,

Not wishing to put a downer on your idea but I think that this type of pump will not be adequate for what you want to do as even at a high speed? they do not pump volume and they pulse with large time gaps between pulses. In my work we use them on aquatic systems to dose the tank water and they run approx twelve times an hour twenty four hours a day and we change the silicon rubber tubes every few months because they wear out. they pump known quantities of liquid which we use to keep pH and uS levels at set readings.

Martin Perman

Gentlemen,

Something else I have just spotted in one of your threads is Power Factor Correction, where I served my Apprenticeship as a macine tool fitter we had two factory's close by each other, the older factory had tucked away in its roof space a very large electric motor with no extended shaft just running constantly and near by was a meter which had a zero in the centre of the dial with -1 and +1. I was told by the works engineer that the motor and meter were there to keep the power factor as near to zero as possible, is this anything to do with what we are discussing here.

Martin Perman

Russell,

I'm confused, if something comes up on this forum I dont understand I research it. The reason i'm confused is that I have found several pieces that comment on Reactive Power, **LINK** but you say it doesn't exist, is it just the terminology that is confusing me.

Alan,

When I bought my Centec 2A it came with a Clarke single phase motor which hasn't given me any worries.

Martin P

Gentlemen,

I to like recycling and making something for nothing, I bought a Centec 2A a few years back that needed a stand, within a few days somebody was offering a two draw steel filling cabinet on Freecycle so I asked for it and it now supports the mill with tool storage uderneath. My main interest is restoring stationary engines, in particular Lister's, and make trolley's for them and recently at work my company dismantled a mezanine floor and I got offered a good quantity of 4x2 box section steel so that is now stacked behind the garage for future trolleys.
