back in my uni days physiology recordings were made using a smoked drum - a messy process of running the recording paper through a smoky incomplete combustion source. Presumably the stylus friction was minimised. Recordings could be stored after spray varnish. Presumably a modern answer would be laser or point light source and photo responsive paper (or just a digital record). My ECG machine used a heated stylus and sensitive paper.

That must gum up the fag paper over time.....😁

And I recall a very aged (well he looked very old) leathery skinned and white haired part-time x-ray tech coming to check my machine in the 70's, First he took a couple of exposures with his arm under the beam to assess the ionization by how his arm hairs lifted. Unsatisfied, he then stared into the tube to assess the cathode heater while running his hands over the high-tension leads looking or losses of insulation...

How come second driver premium goes up...they're just a named driver. If my wife bent her car I wouldn't have seen a need for me to add that as an incident on my next renewal on one of my cars. I don't recall anything on the proposals I've just been filling in asking whether a car I'm named driver on has made a claim.

The reduced policy cost for a second driver is common but also counter intuitive to me as to how that reduces risk. I dug further on other comparison sites and chose a quote from a Co. offering 2 choices; 1st choice was £85 plus optional £39 extra for legal protection. Option 2 was £95 including legal protection!!.

I then rang current provider to cancel auto-renewal and their rep started a discussion re reducing their price. But that reduced price was still plus a setup fee. He tried giving me some flannel about comparison sites selling his insurance at a loss... I pointed out that wasn't my problem and we parted ways.

Sigh.. I have to go through all this again in 3 months for my Tesla. Getting sane quotes on that can be a challenge.

Last year my aged 200sx was quoted at £98. I'm offered an automatic renewal this year £110 Plus £50 set-up fee!

A whole new meercat quote comes out cheapest at £90 which I'll obviously take up. But £50 for pressing a renewal button and calling it a setup fee??? Yes it would share the nuisance of chasing NCD docs etc.

It's evidently a ploy round new law preventing existing customers being soaked with higher quotes.

Other optons include starting with a square bar...no reason a. Chuck key shaft is round..makes any thinner flat indexing a doddle.

Heat it and beat it i.e forge the end

Drill the round shaft and inset a piece of square rounded at one end and pinned, glued etc. Useful if wanting a hardened tip?

Indeed. How about using the silicone you avoided but masking off all the unwanted areas it may contaminate prior to application using a low tack tape?

As described above in this specific case the radiator, coolant bars and coolant pads are inseparable such that the cleaning process required the pads to be lifted. I do own a conductive epoxy but avoided using that in case of future need to repeat the cleaning.
As it happens, I just re-assembled on the theory that the original material would be realigned if undisturbed and the machine currently runs whisper quiet. The fan noise had become increasingly annoying over the last several months in a 4year old machine and doubtless will require repeating at some future time when I shall arm myself with one of the paste materials from the suggestions above.
On previous PCs that I've had to clean the processor cooling systems were fans atop the processors which could be cleaned in situ so the arrangement here was new to me. The face of the radiator was 70% clogged with dust and sorted with a trip to the shed to blast an air-line through from the rear.
The type of thing can be seen at the video time point below, albeit that in my case there were three coolant bars going to 2 different processors.

That's the sorta thing looks like a paste rather tthan liquid for ham-fisted use...

pgk

I've just take apart an all-in-one PC and cleaned all the dust and crud out of the fan and radiator and it all works fine and quiet now.
BUT:

The cooling fan blows air into a radiator which houses some thermal conduction bars terminating in sprung flats screwed over the main processors. Clearly there is evidence of a gap-filling compound and I’d appreciate advice on what to use there if it needs doing again - something that will gap-fill but not glue or drip...

Is there a local r/c flying club? I haven't flown my helis in a long time -most have only 5/6mins time per battery pack but as example my petrol "gasser" is good for 20+.mins aerobatic or 40mins with the original lower performance engine and quick to refuel.

A cording to Wikipedia the barracuda anti-torpedo missile can do 800kph 430knots. Stingray needs a turbo.

I’m guessing that someone versed in the appropriate fields could give better answers. As I understand it submarine nuclear detonations would give different effects depending on depth. Deep enough and pressure contains the blast effect and damps it out dramatically. At a shallow depth you're going to get a massive vapourisation heavy laden radioactive water mist with the greatest danger being atmospheric spread. At an intermediate depth the upward thrust would cause the sort of wave front we're speculating about. Pick a point off the continental shelf and perhaps that would raise the wave height while allowing the spreading waves in other directions enough distance to become less threatening? How far away and at what depth a sub would have to be to avoid destruction is moot.
I recall reading something about the benefits of detonating a warhead above London rather than ground level to vapourise the Thames and reduce the area of fall-out while still creating a blast wave capable of levelling the place...

That was always the 'public knowledge' as a contingency on the premise that London gets destroyed along with main comms systems. If memory serves it was said the BBC has to be off-line for 4 days before our subs can retaliate. The reality is doubtless different with several alternative communication systems available. I doubt that submarine launched missiles can be accomplished from any huge depth and there is bound to be some simple satellite phone that can be deployed on a relay while still deep.

Presumably you'ld risk distorsion but diamond burns at 900C so running a propane flame over it might work?
