Nope. The size is not an issue as a small one is exactly the same removal process as a large one.
Granted, the cast iron ones are considerably heavier than thinner metal, modern ones.

As for your photography question, you've got all the help you need. (8+p

It's really not a big job to remove a rad. from the wall. Even on your own.
I'm not giving anecdotal advice here.
I don't know what problems you lot appear to have had but it's really a very straightforward process.

Mark

Oh, I thought we were talking about painting them not removing them first...

By the way, I wasn't after help in the support thread, but since you take your photography more seriously than most people on here, (no offense anyone, he just does!) I was after your opinion... praise me! Praise me!

Mark, you're so amasing! You're my DIY idol.

For the majority I would disagree, which is why I called it a big job. I think the issue is that people are apprehensive about working on plumbing systems.

I understand that. I'm apprehensive about working on electrics. I'll do it, but I probably have to take twice as long to do the prep. work than others doing the same job.

Mark

Me too. With gas or liquid plumbing you can either see, hear, smell or feel a leak. With electricity the first thing you know is when you feel it. BBBZZZZZZZZZZZZTTTTTTTTTTTTT!

That's exactly what happened to me when I was little.
I was 'experimenting' with an extension cord and I wanted to know how the one lead split the electricity signal - I was only about 6 at the time - in to two.
I took a screwdriver to the double socket without unplugging from the mains first.
I remember a tingling sensation and the next thing I knew I was across the room.
I think this experience gave me a healthy respect for electricity.

Mark

I used to temp at a firm that made smart cards. The section of the building that did the QA testing was kept at a constant 22°C, with aluminium plate screwed over the adjustment controls.
I leant my hand on the wall, my fingers brushed the plate and more or less the same thing happened but not as violently - some idiot had screwed into a live component inside the control unit.

Actually I prefer to unscrew the sockets and then paint around them. Then refix them.

+1, though mine are windows...All of student properties I've lived in have had sash windows. The new property I live in has sash windows.
Why is it that in every bloody house someone has previously decided to plaint the blinkin' windows closed!?

Security?

But you can lock them from the inside...Plus the last two houses I've lived in it would take a fairly hefty ladder to get to the windows...

But you're not about to go out and leave them open, are you?

Laziness?

Oh and fewer draughts.
