    And no, I'm not talking about celebrity chefs! ::)

    I need to find a cheaper source than this...

    http://www.partmaster.co.uk/cgi-bin/product.pl?PID=876981

    Need four of the things and resent having to pay sixty quid (plus p&p) for a plastic knob with crap chrome plating.

    Mind you, the originals have lasted eleven years!

    Get Antony Worrall Thompson to go to Comet or Currys for you, be cheap.
    Or try the local dump, they have loads of cookers there.

    What happened to the old ones?

    Good question Tony. If they are just scuffed and the rubbish plating has worn through, then I'd just get the old ones powder coated. There are some really tough powder coats that look pretty nice, even metallic if you want, and the finish is much tougher than the thin plating normally used.

    Make sure you get polyester powder coat, not nylon, as that has the toughest finish. You can get DIY powder coat kits (I have one) and they do a pretty good job on small parts, but there are powder coat places in most big towns that will probably do a little job like this for around ten quid, maybe less if they have the right powder in stock.

    The only thing to watch is the temperature tolerance of the material the knobs are made from, as the coating is baked on.

    They're PLASTIC underneath that nice shiny chrome look, as descibed in the OP. :wink:

    A few months back the finish on three of them started to crack and now the "chrome" film is lifting.

    It's a 'Leisure' range cooker (part of the Aga group, apparently - or were) and the build quality on the pan drawer is rubbish, the nylon runners more or less collapsed a few months out of the guarantee. Managed to sort that problem and it's been problem free ever since except for the control knobs. Suspect it won't be long before others start to go. There are eight of them altogether, but only three need immediate replacement. It's a cosmetic thing, but on the limit of being obvious enough to notice!

    Thanks Babs. :bigsmile:

    Got that one and one other... http://www.ransomspares.co.uk/parts/search/knob/cookers-hobs/c/default.htm?p=6&ps=&se=NumSold&sd=DESC

    ...off another trade forum last night, so I'll give them both a ring today and try and source the TWO different spindle sizes!

    Eight knobs, all apparently identical except that the two for the ovens have smaller spindles. Go figure. :devil:

    Just like a London bus, you wait ages and then three come along together. :bigsmile:

    Yes, I know that, but it's a COOKER........... :wink: (The knobs on a cooker are almost certainly a pretty high temperature plastic.)

    Many plastics are quite capable of taking high temperatures, maybe high enough for the relatively modest temperatures involved in re-coating these knobs. You can get a near-chrome finish with this process, too, which is why I suggested it.

    If it doesn't have to be gold plated you could try somewhere like Maplin, RS Components or similar who sell knobs for hifi and other electronic kit.

    Thanks Colin, never thought of that one. Gives me a way of describing what the difference is (and why it's there) when I come to order them.

    And Jeremy, thanks, but re-coating is going to cost more than the £4.49 of this... http://www.espares.co.uk/part/cookers-and-hobs/knobs/leisure/p/1599/433/0/0/1107546/chrome%2fblack-main-oven-co.html

    Had the part (or something similar enough for it not to matter in terms of 'fitting in') not been available then it's good to know that the process is possible. :wink:

    Again, thanks all. :flowers:

    Ha! Except that just noticed the knob in that last link of mine has the damned temperature settings on it, whereas the cooker has them on the face of the cooker.

    Back to the lists. :cry:

    There seems to be a lot of very similar knobs. The one with numbers on seems to be cheaper.

    Long shot but depending on the problem, perhaps you could you turn down or modify the existing knobs and fit these to them (assuming they are the right size).

    Actually, we've spent some time looking at those earlier knobs (sounds sad) and realised that the numbers would actually be uppermost when the pointy-thing is set to the gas mark on the face of the cooker, so would eliminate the need to bend down and peer at where the setting is, making things a lot easier.

    One of the other problems with the original knobs may seem a bit trivial, but as it's happened a number of times with a number of people who've stayed with us as well as to us, it's something we'd like to get round if possible. The original knobs have a long bit that points to the setting and a shorter (not that short, either) bit on the opposite side (you can only see the one bit on the link), so that it can sometimes look as if the knob is in the off position when in fact it's still on. On the smaller burners turned down low for a simmer, with the sun coming in through the large kitchen windows it's difficult to see the flame. You take a pan off and finish your cooking and then lower the cooker top (acts as a splash-back when up) which turns off the gas - until you lift it for the next time. It's a while before you actually smell the gas. We're in the habit of always lowering the cooker top, but some guests will leave it up thinking it's a permanent splash-back.

    So changing the knobs to a different type would be a good thing. Finding out if the supplier makes a knob with two different spindle sizes is proving bloody difficult because no one we're spoken to can tell us. Even the "proper" knob doesn't have the spindle size given for it!:devil:

    I think the standard shaft for most potentiometers (perhaps used for the thermostats) are 1/4" diameter.

    No problem measuring them this end of the process, it's finding someone prepared to do it the other end!

    They simply don't give a toss, even when you're looking to buy the originals at fifteen quid a go. You don't need a video link to "see" the shrug of indifference at the other end of the line. Oh to be in the US where customer service comes as the norm.

    "Have a nice day, sir!"

    There, I've given you one dose of faux humanity, and now you can call someone less thick and indolent than a short plank but whose diplomatic skills are as poor as mine...

    I was thinking more about the astonishingly rapid reaction times of US firms when contacted via email. Mind you, the fact that you've got a response at all is amazing when compared to many UK firms. I was very pleasantly surprised that the heated glass people got back, because none of the other firms I found when researching the background to the technology bothered to respond - except for the American companies, but they were dealing with a totally different technology, which I wasn't aware of at the time, but which I became aware of as they described their own systems - which I didn't supply links to in the thread.

    Likewise the firms I contacted when trying to source clipfin material. One company I contacted by phone promised to get back to me twice. Zilch.

    The "Have a nice day, sir" stereotypical response is a bit jaded now as a put-down for the idea that service doesn't mean subservient. London restaurants are packed with foreigners serving table who genuinely want to give you a good experience; who don't feel they have to impress upon you that just because they're serving you makes them somehow inferior to you. The excellent Raymond Blanc programme "Service", which took a bunch of diverse young people from a variety of backgrounds (including one public schoolboy) and trained them in the art of service brought home just how class conscious this society is - and how crippling it is to us as individuals as well as a society.

    Throughout our visit to Canada and the US a few years back, visiting relatives, I was incredibly impressed by the open nature of virtually all the people we met, especially the staff in restaurants and shops. We were there for two weeks and didn't spend all our time indoors, so I doubt we were just lucky in the people we met.

    And around 1995 I did freelance work for a company that was involved in improving the customer service of Woolworths. Bit like secret shopping, I suppose. Staff were being trained and a few of us had the job of assessing how well this translated onto the shop floor. At the start of the programme you could see that staff were having a problem delivering the expected outcome. That "Have a nice day" sounded about as false as it could sound coming from the mouth of a jaded shop-assistant on minimum wage in a town centre branch of Woolies. But as the programme worked on it was becoming apparent that a smile and greeting/goodbye was becoming second-nature and the whole ethos of stores changed. There were still exceptions, but they were singular exceptions involving individuals.

    Didn't stop Wollies going down, but that had nothing to do with staff attitude at shop floor level.

    My internet mate in Nebraska can drive over to his local hardware store and buy the stuff we'd have to spend hours on the internet searching for. He runs a large woodworking company making specialist furniture and office fittings. The people he talks to on the phone KNOW about the products they're selling.

    It's a bit like a waiter being able to tell you what the menu items are made from and what sort of taste experience you're likely to have. It's called customer service, it's all about earning the establishment money so that the staff retain their jobs. The one thing you don't pay for directly is a smile. But that smile is rewarded with either or both a tip and return custom.

    All I want is to talk to someone who can either tell me the diameter of the spindle the knob they're selling will take, or take the time to find out. :bigsmile:

    It would seem that all knob experts have human warmth, empathy and communication issues from your survey so far: some might call them knob knobs I suppose.
