[The Medway Handyman]

Just been changing all my rad valves for TRV's & new lock shields. System
has been in for 28 years + to my knowledge, rads in perfect condition, not a
spot of rust anywhere.

Original plan was to use the existing rad tails (for the lock shields) and
the existing nuts & olives on the supply/return pipework.

Couldn't use either. The rad tails wouldn't fit the new lock shield valves,
did up a few turns but you could feel they weren't 'right'.

Nuts & olives on the existing pipes were even worse, did up half a turn &
stopped, no chance of sealing.

In the end I replaced all the rad tails & supply/return pipe connectors.
Thank the Lord for olive pullers, large allen keys & percussive
maintenance..

Once loose I tried the threads & they definitely weren't right.

Have they changed thread sizes/pitches in the last 28 years?

Dave,

I seem to remeber that around that time there was a bit of a rumpus about
going from the old *imperial* to the new fangled *metric* system - or are
you way to young to remeber that? ;-)

(That included changing from BSP etc as well - for the purists amongst us.
LOL

You're right there John, it is still used in plumbing and pipe-fitting if I
remember correctly - not having a good night tonight though, I can't ruddy
spell and earlier on, I erroneously 'securely' deleted a folder with around
8 years worth of work in it - ah well, that's life, time to 'hunt' around
for the back up floppies and CDs!

Yes but usually made "abroad" and they don't to seem to understand
what BSP actually is when it comes to making the threads.

I know exactly what he means by "but you could feel they weren't

Ouch !
Can I suggest an external hard drive and a program such as Karen's
Replicator that allows you to schedule copying folders to the backup.

Other programs exist, but this has a light footprint and does a straight
file copy so you don't need to 'run' anything to get the backups back.

About 15-20 years ago there were compression fittings about with different
threads and you couldn't guarantee that one make would fit another - I know
because I bought both at the time - grrr. This no longer seems to be the
case. You would have to be unlucky (I have just been doing the same job on
30-40 year old valves and the new ones fit to the same olive/nut). As others
have said, for the iron fittings, BSP has been retained

Because it was so widely used, BSP was simply redefined as being a metric
thread, sized in inches.

Forget the last 28 years - I find 'nuts' from one make won't necessarily
fit another properly.

I now use SecondCopy to copy everything(*) new/changed below /Documents

the server has the last two versions of everything as well. If SecondCopy

Can Karens Replicator be set to run a given set of instructions when a
user logs off? Email someone if it has a problem? And keep multiple copies
on the destination?

With these sort of copy programs and a NAS device costing less than £100
it really does mean that there is no excuse for not having a decent backup
system in place. Gone are the days of expensive or slow tape drives and
multiple tapes and tape changing etc. The initial copy may take a while to
run but after that it's normally only a few tens of seconds.

Thanks OG,

I managed to find all the back-up disks that I have done, and recovered
around 99.9999r% of the stuff - only losing what I have done over the last
week.

It's lucky that this folder is viewed quite often, but only added to around
every couple of months or so.

As for an external hard drive for backups, I have a couple of spare
computers hanging around and I have been thinking of setting up a server in
a RAID-1 format for a couple of months now as a back-up system - I think
that this little error will spur me on to do that job.

Have they changed thread sizes/pitches in the last 28 years?

Where a joint seals on the thread itself then in all but some very
unusually places the threads are BSP now internationalized as Rt and Rp
threads.

Radiators are 1/2" and some older ones are bigger.

The back nuts for compression fittings to BS 864 (or equivalent EN) are
1/2 BSP for 15mm stuff.

The threads for other sizes are not BSP.

Some compression fittings don't conform to the standard and the older the
fitting the more likely this is to be true. Especially if the back nut is
8-sided.

The main problem with inter-changeability of the backnut+olives is that
some (usually older) fittings allowed a longer piece of the pipe to go
into the fitting past the olive.

No, but if you want users' actions to be 'replicated' when they log off,
you do tend to complete the deletion process rather sooner than may be
really desirable. Tho the 2 'back copies' may be useful for a couple of
days.

yes, I'd agree it depends how important your data is.
I doubt the home user needs such intense backups.
Time machine (Apple) does incremental backups every hour
for 24 hours then every day for a week or month then every week for a month
or something like that. I'm not sure what I could create in under an hour
that
would be impossible to recreate, perhaps a high game score. ;-)

And the floppy. That disapeared for us Mac uses before this millennium

Well if your only using a PC for playing games or watching youtube I guess
so but once you start to write letters on it, use email or usenet,
maintain the home finances etc the the data becomes very important. Most
people don't realise how important until they want it, perhaps some
considerable time after it was lost.

A decent backup scheme is not to protect from the accidental deletion of
something, that can be rescued from the trash can. But from a hard disc
failure be that a head crash or the machine being nicked.

Gone are the days of expensive or slow tape drives and multiple tapes
and tape changing etc.

Never backed up to floppy, the stack kept falling over after 50... I did
venture into floppy based tape drives but they were very slow and you had
to change tapes and rotate them in ways I could never quite get my head
around so backups never really happened. Decent sized and fast tape drives
where (and still are) fing expensive.

An alternative to a NAS is of course a multi giga byte USB memory stick
and just copy to that. Has the advantage that you can carry it with you so
it's also "off site".

The initial copy may take a while to run but after that it's normally
only a few tens of seconds.

Provided you don't do much of course.

Well as OLE maintains it's mail folders in a few flat files just a single
new email can make a change to a multi mega byte file. I'm looking at one
users OLE directory ATM, comes to 61M and all the files where changed in
that last users session. As I said it doesn't take more than a few tens of
seconds to copy that lot and a couple of other identies as well, plus
anything else that has been worked on.

Even if you do and you want the machine to shutdown after its finished you
can set SecondCopy to do that (or restart or return to the login screen)
so you don't have to hang around waiting for it.

We were somewhere around Barstow, on the edge of the desert, when the

saying something like:

I'm not sure what I could create in under an hour
that would be impossible to recreate,

Oh, I dunno - imagine you've just transferred some bloody good image
files from your camera over to your hard drive and it goes toes up.

I'd think such a thing might happen relatively often these days.
