Hi Jason,

The engine looks beautifully proportioned. I will follow the series and expect that I will learn a lot from your techniques.

Ron

It looks very good, indeed. I, too, would like to see it in action.

Ron

I find the book very useful indeed.

As I age I increasingly suffer from cold fingers. I have always been a keen walker and climber and, like Michael, I walk 6+ miles nearly every day.

I have tried 'thinsulate' gloves but was not favourably impressed; likewise battery-powered heated gloves (admittedly a budget pair).

In addition to walking I also indulge in archery which places a peculiar demand on gloves in cold weather!

I do not think that any single pair of gloves deals with all situations and hot, sweaty hands are nearly as bad as cold, aching fingers. I have found natural fibre - wool - suit me best. I most frequently use a thin pair of merino wool gloves supplemented, when necessary, by Dachstein mitts on top. When it is chucking it down I use Sealskinz waterproof gloves for walking poles.

I first used Dachsteins fifty years ago. I try 'modern' gloves but always revert! However, I have just looked uo the price of Dachsteins and received a shock. God forbid that they are now fashion items! I thought that they were the mark of old has-beens ...

Thanks, Ramon. I would like to take up your offer.

Ron

Thank you Ramon.

Hi Ramon,

Your piston ring looks great. Where do you obtain that ptfe impregnated yarn? My search has only come up with what I think is the braided ptfe.

Ron

I gasp in awe! I wish that I could see the engine "in the flesh".

Ron

Unbiased, polite and informative - I applaud your post, Ketan.

I have not received Model Engineer 4559 so I thought that I should contact the subscription service.

It appears that there are two methods. The first is by telephone which entails a charge of 7p per minute on top of the BT call charge. The second is by email.

I object to subsidising MyTimeMedia's customer services on top of the subscription price, so email it was.

I received an automated reply telling me that a member of the customer service team would be in contact "as soon as possible". I waited but of contact there was none. Emailed again and received same " contact .., as soon as possible".

Has anybody else experienced this?

My quarterly direct debit is due soon if I do not cancel it .... I wonder what I will do.

If it is of any help: I followed Jason's and Neil's advice and loctited and pinned the crankshaft of a 10V. It has proved to be fine.

I agree with Mike. I have enjoyed this issue far more than any of the recent others. It is like the MEW of the first few years. It may encourage me to keep on subscribing.

Well done, Neil, and thank you.

I, too, would be very interested in "short, snappy build articles".

Hi David.

Thank you for writing this build thread. I am at the same position as Stuart.

I learnt a lot from Harold Hall's 10V MEW articles and web-site. I feel sure that I will learn some more from another editor of MEW!

Ron

Wow, Jason, that is so neat!

Thanks.

Ron

Thanks, Neil.

Thank you very much, Jason. Just what I needed to know with pictures as well! I must learn to silver solder as neatly as you.

Rod: you have expressed what was puzzling me. Is pinning now a custom hallowed by necessary past use? Could the pin support the "glued" join from the varying load through the cycle?

I do not know but I have read that Loctite 638 is very effective. Perhaps the pinning is to insure against a sub-standard joint resulting from poor Loctite technique?

Thanks, again.

Ron

I have just fabricated a Stuart 10V crankshaft. The short pin and the axle were sliding fits in the web holes and cleaned with acetone. My intuition is that Loctite 638 should hold it satisfactorily.

However, the plan indicates that pinning is expected.

I have searched the site and found good information, particularly from Ramon Wilson, but please could someone with experience advise me on the following:

(a) Is 1.6 mm mild steel (panel pin) a suitable diameter?

(b) The Stuart plan shows the pins extending through the “flat side edges” of the web. Would it not be better to go through the “curved ends” of the web?

(c) Do pins extend right through the diameter of the shafts into the web on the other side?

(d) Do pins need an interference fit such that they have to be inserted with firm taps of a hammer or will a sliding fit with Loctite suffice?

John: thank you very much.

Ron

John: as you have used one and have real, rather than theoretical, knowledge, how big an engine could one of the Bambi compressors operate?

If I have it correct they supply 30 litres per minute. What does that correspond to in, say, running Stuart engines?
