I assume that they want the cute look without the gear, but airflow can be a complex thing, especially when one has a large metal brick...

Well, I'm doubly glad I asked then as I see where extrapolation would have got me!

Yes, railroaded!

I hope you don't mind me jumping Balmae. - There are several controlled impact areas. That is areas that are contaminated with one thing or another; the Chieftain P5 is sat in one of them. I doubt that one will be "Cleared" in our lifetime. Shame really. The Comet 28 is often shot today with all sorts of high explosive; most of the other targets haven't been shot at for years. The Tortoise was engaged by yours truly about 1978 from a Khalid at night firing DS/T. All the big holes in it are from APDS from Chieftain.

I see, so some other generation will maybe get the chance to rescue those...

For the Khalid (I had to look that up), was that for trials or training?

Hi Trevor its a casting mark, there's no sign of any repair inside the block & one of the other blocks is similar, they must of had some poor moulds in the war ?

Or, Ian, perhaps they had a problem with cracking and this was a temporary fix before re-engineering the whole thing. It would be interesting to compare the block to a later equivalent block.

trevor

Hi Trevor I don't know what you've seen but they both have identical rear bodies, wooden frame covered in steel & wooden tail gates.

Ah yes, I see, it must have been the colour and angle, but I thought that the sides of the one you are working had wooden sides :nut:

On another note, is that a repair or just how the casting is, as it looks like a patch down on the side at the engine number end of the block? As you can probably tell, I do not know much about Standard Tillys.

trevor

Nice, very nice in fact, but why has one got a wooden back and the other steel? I assume that they are off different dates, or is there some other reason?

trevor

Lovely shots - I like No. 28 Comet, it looks almost like a model.

I have a question, though, what exactly is a controlled impact area? Will they always remain off limits, or do you think they will be cleared eventually?

trevor

I have a small line-up of new looking but non functional original plugs that I have yet to think of a use for.

 

David

Find a strip of steel, drill 12 holes in, roll into a hoop and weld, add a clock mechanism in the centre and insert twelve spark plugs in the holes to act as hour markers?

trevor

A nice piece of work, you must be glad it all worked out. Is there some kind of bump stop that makes sure that on max upward deflection of the axle the steering arm does not contact the chassis rail?

trev

Are the seals supposed to look something like you would have on the suspension ball joints on an old Mini?

trevor

Yes and why was my thank you post removed too, can't you be civil on here anymore ?

As the forum is an IT system, it could have just been eaten by the server

trevor

I am not familiar with that carb, but is the float height set correctly? How are you checking for it running lean, by checking the spark plugs?

Carb problems can be quite tricky, but I reckon we can solve this

I have a conundrum for you that has puizzled me for some time. The 'change speed and brake operating bracket' on the leyland S type was significantly modified for use in the c.1912 S3. My chassis, which I believe to be an S2, utilised the earlier version. BUT, I have a perfect and complete example of the S3 'bracket'. Do I use the latter or do I fabricate a copy of the earlier version? Robert

It is your vehicle, Robert, what is your gut instinct?

trevor

Ah, it is no longer 'that rusty frame' but part of an actual motorcycle again!

trevor

I used the online diagnostic tool Google before I even looked at the first one, it was a well known problem! What I did not mention was that once the plug had cooled they would run fine again for 3-4 minutes before cutting out.

As an aside, many years ago while I was still young and foolish, before I got older, I took my modified Honda C70 down the Alps to ride the trails there. I soon discovered that as the engine got really hot, as in doing 5-10 mph up a very steep road, it would start to cut out. Changing the plug for another old one would solve the problem temporarily, as would leaving the bike to cool. A new plug would solve the problem for maybe a day.

The real problem turned out to be the location of the condensor, mounted inside the generator on the plate that divided the generator zone from the crankshaft zone, and the extra hot oil lapping around on the other side of the plate was killing the condensor. So the Honda engine may have a problem, and it may indeed be the plug, but it could also be something else.

Interestingly, I removed the condensor and replaced it with an old Mini condensor I happened to have, which I mounted on the frame in the cool, cool air about a foot of wire away from the points. This ran without fault for several years, as long as I had the bike, which begs the question of how close to the points does the condensor need to be?

trevor

Ah, almost brings a tear to the eye, but I blame the dust in my room...

I tend to agree, screws were quite expensive and would typically be used for things that may have to come apart later. I have a wooden toolbox made by my grandfather's brother, a carpenter, in 1915 and the only screws it uses are for the hinges. A well inserted nail or a wooden dowel also means that one can produce very tidy-looking cubes, with no filler being required or visible screw heads.

Pete I hadn't actually thought about an equilibrium of metal transfer. But I suppose it must be so, when arc welding I assume that all the metal from the rod does end up in the weld.

Well most ends up in the weld, the rest on your walls, clothes, in your lungs.... :undecided:

I sometimes wonder whether there is a maximum sustainable spark flame length for any gap, because the elements of the spark seem to travel in an oval shaped field rather than a cylindrical one. If we had, for arguments sake, just one gap in our HT system between coil and cylinder head then would the maximum size of this gap be noticeably less than the maximum combined lengths of all the gaps we do or may have: rotor, spark plug and air gap resistor? Is the fatness of the spark a limit on its maximum length?

trevor

Well, for the rotor gap I suppose that there is probably the issue of producing a wider range of rotor arms, and then what happens when eventually someone fits resistive leads or caps to your system fitted with a resistive distributor?

Ah, so is this an example of an early type B hull with the blanked off exhaust ports then?

trevor

Ah, thank you, Jules, I had forgotten about those balls!

trevor

I am interested to know why the passenger side mudguard has a hole in the outer edge for the mounting bar but the driver's side doesn't? Is that how they were?

trevor

Ah, thank you, that makes sense, are the A type hulls still relatively common as survivors?

trevor

I think there is a rare Mack LPSW tipper on the LHS of the bottom picture. Only 55 were made.

Ah, you answered the question I was going to ask

trevor

Why does Comet No. 5 have a different rear plate, without what I assume (perhaps foolishly) are exhaust outlets that can be seen on all the others?
