The manual I found made for a dodgy startup in my mind so had kept quiet.

1 Switch on

2 Select forward or reverse

3 Adjust speed.

Would have preferred number 2 to have been first but......?

Found this list with some colours shown...

I did see on one site four different temperatures of "red" as in seen in the dark, twilight, daylight etc.

Agreed that the isolator should be used, perhaps my wording was unclear. In fig 2 the machine is not separated from the incoming neutral in the off state. 

Any neutral fault upstream could be fed to the machine, unlikely, sure.

Came across a user manual but apart from seeing that it is a vee belt no sizes.

Looking at Fig 2 in the original post I would consider it dangerous because even in the 'off' position there is still the potential for a voltage to reach the motor.

Although the neutral should be at 0 volts a fault upstream would feed through the relay coil to the live feed to the motor or your fingers if you are during some wiring mods at the time.

Plumbers merchants should have those

One suggestion I've seen is to crimp one end and then fill the tube with a low temperature filler such as cerro alloy or even plumbers solder.

Form your bend and then melt the filler out of the tube.

There is a product called ACF50 which was designed for corrosion proofing aircraft. It is also well used by motorcyclists to protect their machines.

It isn't cheap but does what is says on the tin. A small squirt goes a long way.

Aren't most of the bits all travelling at the same speed, at their particular altitude, otherwise they would fall out of orbit.

If that's right then they will only impact something in a lower orbit when they themselves start decaying.

My head's beginning to hurt now. 

You can wire up more than one switch if you want to.

Personally I would fit a contactor in a box with the knock off button(s) wired through the contactor coil circuit. The lathe, or workshop, power supply going through the contactor.

Thanks for that info SOD, I'll need to update an old lady friends' TV for her, being partially sighted she can't do a lot about freeview updates herself.

Their website has "closed 24th November" on it, whether that means for just a day or maybe a week I don't know.

Sadly that push button contactor is not designed to have remote stop/start control.

If you can find a way to get at the wiring to the buttons you may have a chance.

You shouldn't really wire one phase through the limit switch as the switch probably is not designed to take the current through its contacts.

Checking with Google brought up a 2010 thread from here, diagrams included....

I think it is channel 81 on freeview.

Thanks for the reminder.

Ho Ho indeed 

Any oxygen with propane will give a good flame, most commercial users working on sites nowadays don't use acetylene but propane as acetylene is not allowed on site.

As V8eng has suggested but a bit cheaper is this dual sensor data logger. You could then record inside and outside shed temperatures.

Simon, it seems to be based on the speed of the object hitting the lense.
