edit or even:

I'm still working on how to get this in focus

To display a higher resolution image you need to either use the original upload method, that starts with this tool:

or copy and paste or link to the image on an external server

If you use the shortcut upload, the one that starts with this tool:

it automatically and irreversibly reduces the resolution.

Anthony, I assume you are replacing one that is suspect, is the thread on it parallel (that will be UNF) or tapered (NPT)

@JK this is using the upload tool.

Andrew, well, it's not suspect, but while replacing many other bits it seems a nice thing to do, in fact it would be the only bit not replaced. Interesting in that I'd have to remove it to check things... I suppose I can do that being quick with my finger.

What's NPT? (I'll google it). IN fact I'll go and stick my finger in the dyke. Back soon.

The UNF will seal against a fibre or copper washer against the head, the NPT taper thread will seal on the thread tightening in the hole

"@JK this is using the upload tool."

As upthread... there are two different upload tools.

fresh pics in o p, looks tapered to my surprise, I thought not until putting the caliper across it. And does 487 mean anything useful?

[OldAndrewE]

I suppose one option is to ask the gauge manufacturer (I suspect at that age they will be Smiths rather than Caterham branded).

Caerbont or Speedy cables should be able to tell you what a compatible sender will be

4 87 Date of manufacture?

@jk

yes the one you introduced me to that goes via the server. Let's call it the complex tool.

As it happens since then the two of the sender above are just simple uploads using the simple tool.

It seems if the image is already cropped and the subject covers most of the image area, the simple tool works, but if it does not and cannot be cropped, such as a text type document, then the complex tool is better.
