Thread: Overwhelmed!
07/04/2020 15:50:56

Jeremy, as a beginner myself, I did buy several items not yet used, but as a basic list, I would say a set of HSS lathe tools, likewise twist drills in at least 0.5 mm increments up to 10mm. a tailpiece chuck and a bench grinder. I find that in the few years since I began, knowing little, these are the items I have used the most.

Thread: Unintended...?

My wife, Deborah, was amused to see this cover, in that the title, 'Model Engineer', is accompanied by an alert for an article within, called 'Boring Eccentrics'...

Thread: Could bigfoot be real?

Yes it is real! Observe, door laid flat, bearing vestigial vice, but with amateur radio station built on it it.

Thread: Electrifying Women - Cherry Hill

You rang???

I spoke to Cherry by phone only a couple of weeks ago, she sounds her usual bright and cheerful self.

Thread: Spring's a-coming

Bad choice of picture, JA, snowdrops can flower before Christmas, any year.

Thread: Solon soldering iron
11/02/2020 10:41:07


I refer the honourable gentlemen to the Henley Solon Owners Club, started in the pages of Club News. There are a multitude (3) of enthusiasts/obsessives, membership is free, and you get nothing for it. (Unless, of course, you have spare parts to help the afflicted above)

Thread: Old Computers - why do people bother
07/02/2020 12:05:51

Bandersnatch' mention of obsolete computers reminded me of my time with a NCR 500 visible record computer in 1968. When it broke, we would go to their office on the Leeds ring road to deal with that day's transactions. Ideal in theory, but the temptation to manually correct the entries on the card rather than ask my staff to do it on the machine was impossible for some to resist. Also, the abrasive iron dust from our foundry next door didn't help.

I also remember a statuesque young programmer called Marion de Vries.

Well! A host of posts about bikes and even one Clarence Clutterbuck, but nary a mention of Ogri! (And Malcolm)


Thread: Amplifier Repairs..
05/12/2019 06:59:33

Mention of my favourite guitarist got my attention. I have probably every one of the Shadows recordings, and regard him as unique. However, I have recently discovered Albert Lee, and wonder why it took me so long. Anyway, these last two postings made me think about the varying sounds to be obtained from ostensibly the same guitar. Albert Lee often plays a Fender Telecaster, yet makes it sound completely different from any other player. The same company's Stratocaster has a recognisable 'clanky' sound, in the hands of many.

Thread: Aircraft General Discussion

My pilot friend says the Skyvan had a roof hatch in the cockpit, which always leaked..

Thread: Exactly...
09/10/2019 21:56:31

I have it, although under its previous title, The Perfectionists. Don't be fooled into buying it twice.

Thread: What the he**
24/09/2019 06:15:08

I once had a coil spring break whilst I was parked! It was on a Bedford CF van. I also had continual trouble with the front shock absorber mounting becoming loose.

Thread: Rip-Off? Don't judge by web domains.
17/09/2019 23:21:48

Hi all,

My Practical Wireless article was July 2018. Sorry for the delay in replying, I was distracted, it is our 14th wedding anniversary.

I confirm that my clock keeps good time, close enough not to need resetting between power cuts etc., (roughly yearly) There is no backup battery. I don't use the alarm setting, but in another, more complex kit, the alarm time creeps backwards by 1 minute per day..

17/09/2019 05:21:58

Absolutely, XD. I wrote about these kits in Practical Wireless a year or so back. (Details when I wake up) I bought a handful of them for a quid or so, and use one as a workshop clock. just because the asking price is ludicrously high does not make it 'rip off', in that one is free not to buy it.

A book I was interested in is priced on ebay at about £52, another at £40+, I bought it brand new, from a routine bookseller, for £16,99, yes, it's still in print!

Thread: Mains power supply for 12v dc motor
31/08/2019 08:16:00

Brian, LED's draw miniscule currents, of the order of milliamps, individually, so a lighting controller would be far too weak. The idea of a 12 volt battery is a good one, as is a PWM controller. I have one costing about £10 which will handle 60 amps. **LINK**

Hang this off a suitable power supply, say 12 or 24 volts DC , like this: **LINK** and Robert's your aged relative.

Thread: How can this work?

Thread: strange power socket
16/08/2019 10:33:32

S.O.D., I have one of those 'alternative' 13 amp plugs. I often wondered at its purpose, and only kept it as a curiosity.

Thread: Is there a type of Sellotape/"sticky-backed-plastic" that forms a PERMANENT bond
30/07/2019 20:25:52

I was going to suggest Kapton tape, too. What Andrew has is called self-amalgamating tape, much used for outdoor sealing purposes. Stretch it round the item to be sealed, and it bonds with itself, can only be removed by destructiion.

Thread: 3 phase - radio puzzle
30/07/2019 16:47:55

Look for IEC (International Electrotechnical Commission) EMI (Electro-Magnetic Interference) power line filters, about £10, they plug in, you don't need to open them up.
