So what sort of age is a board like this... :C

Bottom two Pyros are incoming supply....

one feeds top switch & 4 fuses

other feeds bottom two switches and fuses..

 

Both single core with sheath providing Neutral return..  (and Earth)

Distinct lack of separate Earth and Neutral bars!  

{may be tricky getting an RCD not to trip on those :unsure: }

 

Its an old council house..

There is a second Wylex box supplying some circuits (PVC T&E) on an extension that was added on..

 

But some of those top fuses are still supplying cooker, some sockets, and some lights... 

 

Pendant light opened up..

That looks like a good non-combustible enclosure, and non-combustible cables for that mater. So no worries with 421.1.201.

2BA's, my local wholesalers used to sell them. 

I have a stash for emergencies...

Worked in a ex council place where upstairs it was metric and downstairs was imperial :o:lol:

 

Watch out for asbestos flash pads or tea strainers as steptoe used to call em...

My old mum had a cracking saying, whenever she knew one of us was wrong, which in my case was usually after she'd had a few drinks, she'd say, "well it's not often you're right but you're wrong this time" , always makes me laugh thinking back on it now.

Renovating some old switchgear I ordered a set of various BA nuts, bolts, etc, I got a metric set. I kept them and put in a new order, guess what arrived. I had to go to the wholesalers trade counter to be told “we don’t stock BA stuff so we sent an alternative”

We (me and my former boss) used to refer to this as imperial (an obsolete remnant from a distant bygone era). If it was non-metric, it was imperial and that was that. It took a toolmaker to tell us that there were different types of imperial threads. The only way to encounter this weird sorcery was to drill and retap to a bigger metric size.

 

My brain can't comprehend inches, furlongs, thous etc

I haven't even got a tape measure with imperial markings on it. Not used one for years, not that I ever used the imperial side, it just got in the way and made things more inaccurate!.

Theres a few different imperial threads to choose from, you need one of these: http://www.ebay.co.uk/itm/Zeus-Precision-Engineers-Metric-Data-Book-Chart-Charts-Reference-Sizes-Tables-/310893777034

 

I had one a few years back, but I haven't seen it in a while, at the moment, I am not sure whether the point at which it disappeared corresponded with moving house, or changing van as they both happened within about a month or so of each other. But I guess quarter to two isn't really the time to be turning the house upside down looking for it! I haven't Seen my copy of https://www.amazon.co.uk/Newnes-Electrical-Pocket-Book-Books/dp/0750647582  

 

since about the same time. hmmm

Presto used to publish a hand book of conversions and equivalents to be issued to apprentices.

 

I had a Zeus book until I lent it to a mate.

I still have my Zeus and will be using it within the next hour!

 

just bought a quick release indexable toolpost for my No. 1 lathe and the fixing bolt is not long enough so need to knock up a 1/2" x 13 stud

 

better than shopping in Tesco though😱

I have the infuriating (so I'm told) habit of mixing my measurements,

I'll measure something at 3' 8" 4mm ,or, 7m 4" ,  apparently some people don't like that, i just measure to the nearest mark on my tape,

I still have a Zues book, & use it.

Also carry BSW, BSF, UNC (1/2" only, who can tell me why?), & BSF as well as metric coarse & some fine, with conduit taps & dies on the van.

Keep a greater range in the workshop.

 I can't cut metric threads on my Harrison as it's imperial & I don't have the right changewheel for it.

I was cleaning up some 3/4" UNC threads on Wednesday, mounting bolts for a limit switch rail!

My lathe is weird. It has a mixture of BSW, UNC, BA,UNF ....it's just the way they were made.

bought a new cheap quick release toolpost from CHRONOS but my existing bolt was too short

so, turned down a big bolt to .500" at each end. BUT my lathe does not screw cut.....ARSHE!

so over to other lathe BUT it is only a little Hobbymat. Brilliant for small stuff. So after 30 mins of swapping chuck, change wheels, speed etc off I trot. Crashed and burnt, machine struggled , steel too hard, tools carp. Off to pick up 1/2" UNC die from my mate on Monday.

on the plus side found a long forgotten tub of chasers, dies , taps etc UNC and BSW...but NOTHING 1/2" UNC,

 

hey ho!
