    Day rate advice

    I think you're lucky to be getting off with the £400. Out of that he's to pay his apprentice a wage, an employer's pension contribution, whatever other benefits the apprentice is entitled to and that's all before he takes his own wage and repeats the process for himself. Unlike council tax the...

    Should i replace old copper pipes?

    If only 25kW then your piping at 35mm seems way oversized. I'm running up to 36kW on 22mm quite happily. Yes, your water will flow very quietly but a waste of boiler fuel, heating up a bulk of slow flowing water and a waste of money buying oversized copper. In comparative numbers 22 = 8/m 28...

    Should i replace old copper pipes?

    Why 28 and 35mm heating pipe for what is a pumped system - is it a mansion you're working on ?. Most domestic pumped systems are plumbed in a mix of 22 and 15

    Should i replace old copper pipes?

    If it was mine, I'd change it. If you're completely renovating then there's a good argument for changing out the old copper. If any of those joints, especially where there are 'adapters' converting old imperial sizes to current metric, decide to weep after the floors are relaid then you'll be...

    I used to use one for tracing mains wiring buried under plaster. Simply placed finger on one connection on the jack and dragged the tip of the jack across the plaster.

    One of the main problems I found with the recent concept of learning and examination via the internet was that there was no 'practical' tuition. So I ended up with a full licence, a nice TX/RX set-up and trepidation about going on the air. You can read all the books in the world and listen to...

    Big boys cables!

    We once ordered 100m of high voltage (6.6kV) cable for a project on our offshore oil platform. Can't remember the CSA but it was in excess of 4" diameter and would have put a smile on an elephant's face :). Anyways, the supplier called us up and said he could supply 99metres now or we'd have...

    Conversely, or should that be perversely, I wouldn't mind a look at the 'old-style' papers if anyone has them.

    Yep, the doorstep was as far as I ever managed to get !! :rolleyes: My original halls was in Bunhill Row just up from Moorgate Station. It was a "mixed" hall, in more ways than one. One Saturday night the fire alarms went off and we had to evacuate the building. The head count was around...

    Amateur Radio

    When I was doing the intermediate exam in one of the questions I was convinced that none of the options were correct so simply guessed at the nearest. I said this to the online invigilator (done via Zoom) who managed to keep dead pan in his suggestion I took the matter up with RSGB. I...

    Amateur Radio

    The RSGB "Exam Secrets" booklet is good in that respect. It not only gives you the correct multi-choice answer but follows it with a paragraph explaining why it's the correct answer. Almost as good as a human tutor. Like many during lock-down I sat Foundation, Intermediate and Full. We might...

    Laptop with a faulty power port

    Post at least 3 clear photos, one looking into the connector end, to determine if it has 2 or more connections and the others showing both sides of the circuit board where you've been attempting to remove the power pole. You will also need a multimeter - a cheap one will suffice

    Laptop with a faulty power port

    yes - no - maybe yes - if you get polarity correct and there's no damage caused by your previous attempts and there are no control lines between laptop and power unit no - if you fail to comply with any of the above maybe - if the gods are feeling kind
