We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Guy King saying something like:
A big crowbar would be enough, iwt. By 'big', I mean mind-bogglingly big, of course.
It would be a little user unfriendly though.

I went to sagulator to caculate the required wood size for the lever. Figured it would have to be a very fast and tall growing tree, so the wood will be cypress (Leylandii). I typed in 93,000,000 but noticed it had no button for 'miles'. It also has no button for end load. Lets say
5% sag could be tolerated, that would be 4.65 milion miles of sag. Typed that in but it seems to think its an invalid amount of sag. Not sure why.Anyway when I went to calculate the required beam size, it thought the whole situation was invalid. Odd.
PS it looks like sagulator has been removed, but is still available via google cache. Grab it now if you ever want to use it. I guess its cos its not able to work out simple deflections such as this one.

The Sun would be OK ;-)

After you with the asbestos shoes.
Thanks for everyone's help and suggestions on this - it took a LOT of flushing, and still I can hear the occasionaly bit of grit passing through the pump, but it's heating the water nicely now. As it's not leaking, I'm going to drain one more time, then use the antifreeze mix (bit pointless for the summer, but I presume it will have an anti-corrosive in it).
I can see why the pump was seized now - I took it to bits and it's just one big soup of rust!
I'll see your daughter (oo err) and raise you a particle physicist.

Well, if you have (as it sounds like from your first description) an open (vented) header tank, and an iron pump (intended for use on a closed system, where no new oxygen is introduced after the initial oxygen dissolved in the fluid that's sealed in the system rusts out when first filled) that's going to happen. Systems which have open vents (and thus keep adding oxygen as rust happens) need to use (more expensive, generally) bronze pumps (and copper or suitable plastic pipes, not iron pipes). You could perhaps convert your header tank to a sealed-type (bladder) expansion tank and a pressure relief valve, thus making it a closed system, which would have a limited amount of rust, using up all the oxygen available, and then stop rusting.
I'd still give it at least a couple of weeks before changing over to antifreeze, as antifreeze won't stop the rusting as long as it's an open system, and some leaks may take time to show up, or there may be other problems that work their way out - this thing clearly sat for a long time before you got to it, so give it some time to run.
Thanks for the warning, but the bookmark I have seems alive and well to me

Oh no, not the asbestos thing again.
Typical chippy? Doesn't bother to take into account the variations in the direction of gravity along the 93,000,000 miles and gets it all wrong. I bet your doors don't fit properly either. ;-)
Don't need one of them, I can DIY it.

Don't leave us in suspense. What sort of temperature is the water off the panel and how hot is the water in the cylinder?
thanks for the update/correction. I'm not sure which is which, but as long as its online somewhere we can continue making mistakes with it.

Oh, _thats_ why I have so many problwems with woodwork. No gravity calculations. Is the situation one of levity or gravity?
