Pet hates ?

[N_Cook]

Great dollops of that white goo between metal to metal thermally conductive
surfaces. Heatsink to metal casing in amplifiers etc. I'm not sure why it is
even necessary with perhaps 20 square inches of contact and bolts between. I
always wipe away with paper etc on first parting but always some gets on my
clothing - I've not worn white lab coats for many a year.

Heat sink compound is usually very necessary.

One of my pet hates is torx screws with a pin in the center.

Me and white heatsink goo have a very bad working relationship. I only have
to walk into the workshop when there's something on the bench using it, and
all of a sudden, I'm covered in the rotten stuff, without even going near
the bench. At least it seems that way ... :-\

The harware that I always have problems with in the UK , never organised a
stock of, is UNF and UNC nuts and bolts for USA kit. And of course,vice
versa, repairers in USA never have metric (and lesser extent BA) for UK and
Japanese kit

I once got in a lot of trouble with my boss when I was young and worked for
a U.S. based company. At that time, I didn't understand that there was a big
difference between British 'tongue-in-cheek' humour, and the much more
direct U.S. type. I was talking on the phone to one of the designers of a
piece of equipment that we sold here in the UK, and asked the guy if he
could arrange to send me some screws for the cabinet, as they were a thread
that we didn't readily get over here. He asked if I knew exactly what size
they were so I replied, quick as a flash, thinking that I was being funny,
"I guess that they are round about 3/16ths APF." "What's APF ?" the guy
asked. "American Piss Fit", said I ...

Stony silence on the phone. Half an hour later, I was summoned to the boss's
office. Apparently, the guy had been really offended by this, thinking that
it was a slur on what he considered to be good American engineering, and had
called my boss to complain about me. Just goes to show how easily offence
can be caused between nations, even when they speak what's basically the
same language ...

While on vacation in the Dominican Republic we ran into a really nice
group from the UK who were there for a wedding. We would hang out and
talk with them down at the in-pool bar almost every evening. I never
quite got used to them asking me to bum a fag. I'm from the US and I
smoke cigarettes, not fags.

It's hard /not/ to interpret such a description as an intentional insult. I
can't imagine what it actually means -- in any innocuous sense, anyway.

Can't afford $5 for a set of security bits?

Yes, but given the frequency that I run into those I find my punch set
and hammer tend to do the trick - security torx to just torx!

Overuse of that stuff is worse for thermal conductivity than none at all.
I've clean up gobs of it since they started using it decades ago.

This is something I'm currently wondering about. I have a fridge-like
thermo-electric cooler than has two sections, top and bottom, with
different temperatures. The top suddenly stopped getting cool at all, so
I took it apart to figure out why. The fans and voltages were all there
so I broke down the heat sinks on the bad one to get to the Peltier
device. With it isolated, I powered it up briefly and much to my
surprise the Peltier device got hot real quickly with the opposite side
getting cooler. So the device works, it has to be something with the
heat sinks?
They did use white goop on both sides, but very little and it was
already dried. The heat sinks are milled flat where they make contact
with the Peltier device, so my thinking is they need new goop.
Looking around I found that Star heat sink compound is about the best
you can get, so I ordered some. It just arrived the other day so I'm
planning to clean up the old goop, put on some new goop and hope for the
best. I don't think too much would be an issue in this case, I want it
as cold as possible.

As long as there is no liability involved. If someone else opens it
with a 'just torx' tool and is hurt or killed, you could be sued. I
just carry the security tools in my toolbox and and ready for a loot of
different hardware. I even keep Posidrive in the same toolbox.

Worse, hotmelt glue or cyanoacrylate on a solder joint. Hit it with
the iron,
and the tip seems like it'll NEVER get clean again.

Oh yeah, GM delco car radios, IMPOSSIBLE to work on those circuit boards
due to some resin/glue coating on everything.

** When you separate the metal parts - cover them both with " Glad Wrap".

It later peels off easily and leaves almost all the white grease behind.

Anyone here remember the Bose 1800 /1801 amplifiers ??

Discovered this trick when servicing those horrible POS.

Remember them! I've still got one, still works too. Not that I would use
it for anything other than a door stop mind.

Here in the colonies, whenever I have a piece of unrepairable Made in
Japan, Made in Tiawan, Made in Korea kit, or Made in China POS that is
going to the landfill, I use some of my 'mental health' time to
disassemble the thing and toss all the screws, nuts, washers, shaft nuts

There ya go then ! Anyone from the UK would see it as a quick-fire
throw-away line, and would laugh at it. It's sort of intended to be
'barbed', but not in a malicious way. It's a very hard to describe form of
humour that is quite prevalent over here.
