Thanks for posting that Clive. I have the same model so I have just had a look inside. It doesn't have the same fault but I noticed that the aluminium foil sticker holding the thermocouple in place was coming loose and in danger of landing on the circuit board!

That's a common trick. Same goes for plastic sachets of handwash and fabric softener. I used to buy paper sachets of sweetener refils for SHMBO's dispenser until I discovered that it's 25% cheaper to buy the new plastic dispenser.

Agreed, so what are you objecting to? I have found from experience that 5% sulphuric acod splashed onto the skin is not problem if washed off within minutes however I always wear goggles and gloves when pickling copper. In school metalwork in about 1960 we were not even supplied with those, just tongs.

Copper does react with concentrated sulphuric acid and with nitric acid in any concentration. It doesn't react with hydrochloric acid at all nor with dilute sulphuric acid. Hydrochloric acid produces corrosive fumes so isn't nice in the workshop hence the traditional recommendation for using dilute sulphuric acid for cleaning boilers of oxides and flux.

Sulphuric acid isn't terribly dangerous when diluted to about 5% concentration (add the concentrated acid to the water not the other way round). Wear goggles to protect your eyes and if it is splashed on the skin wash it off with plenty of water.

Well, I use permanent marker for marking out and have never noticed any improvement in the cutting. It will be interesting to see the results of a controlled test.

Clockmaker's broaches work well. They are not expensive, about £2 each when I last bought some. They have a taper of 1 in 100. Make sure you get a cutting broach not a smoothing broach. Unfortunately my favourite supplier, Meadows and Passemore are closed for a holiday and premises move at present.

I've used Linux for over 15 years now and never phoned the help desk. Oh, there isn't one. There are however forums (fora??) for each distro that are full of helpful experts.

No, after you have had chicken pox the virus can remain in the body in a dormant state and re-activate later in life.

I've not tried it but I believe you can run OSX on a PC using Virtualbox running under Windows or Linux. Can't imagine wanting to do it though.

.My sympathies Ron

I had similar symptoms about 12 years ago. My GP sent me to a rhumatologist who did x-rays and blood tests and diagnosed chondrocalcinosis, otherwise known as false gout. He prescribed anti-inflamatory tablets to be taken for a few days when it flares up. I can now recognise the onset of symptoms and take the pills for three days and it goes away. Still eating rare steaks occasionally and drinking red wine every day.

What operating system and what browser are you using. Do you have Java installed?

The more information you can supply the more likely it is that someone can help.

Copper boiler? Silver soldering = brazing with silver alloy, that's normal.

Suitable primer available at branches of Castorama: **LINK**

I used to write down the ten's compliment of the digits and then reverse them. These days I can't be bothered and just use the same pin number for all my cards - but don't tell anyone!

Russell

If the suspension is Vallet style you may have to buy suspension steel and make the suspension yourself. Ian Cobb at http://www.clockmaking-brass.co.uk/ supplies suspension steel in a wide range of thicknesses. He can also make up complete suspensions.

It's often my first goto reference.

How about this one: **LINK**

Wheels and pinions are available ready cut but it might be worth making a dividing attachment for your lathe to cut them yourself.

Russell

Err, "bang on" is not possible. What tolerance do you really need?

Russell

Yes, it's important that the register locates the backplate and not the thread so the thread should be on the loose side. I had the same problem with a backplate for a 3 jaw chuck a while ago. I eased off the thread and it locates fine now.
