Draw wire through 130m duct

Using vacuum you're restricted to atmospheric pressure - at very best. No such restriction with compressed air. If you've got a vacuum which blows as well as sucks, the blow part will be more efficient.

Of course it was a terrible idea - but the blocking of the RC signal is irrelevant because you don't need to control the car - you just lock it into forward and I did say that you needed a strong enough draw wire to drag it back out!

Borrowing from 2 of my immediate neighbours would get me 45m of drain rods ...

Am I in everyones killfile or something? I posted a link to a hire shop with a duct rod in it the other day and no-one seems to have read it?

If there is a problem with some of my posts not showing please let me know. Thanks.

Your original message appeared here, and made good sense. Duct rod,

You posted "the right answer", hence the silence :-)

Hmm, I'll have to stop doing that then.

That's alright then, I'll put it down to people not being fully up to speed with how to read a thread\click links etc....

There are many who read an o/p's post and reply without any reference to the rest of the thread, leading to many diverging non-solutions. I'm sure the o/ps reads all the posts so will see the useful stuff. That said, many o/ps don't acknowledge helpful posts.

Rest assured, you're on the white list in my newsreader (even if your current solution is 10m short of the o/p's requirement) :-D

Ssssh, I was hoping no-one would mention that bit too much.

But, longer ones are available, I just didn't see any the other day.

I believe this may be one, but a picture would be handy.

I think the above link is the the cobra half way down the page here, but not sure, a phone call may be in order.

Or even this one from Brandon, looks a good price too. Not so many Brandon tool hire places though as Speedy's or HSS's

Ferret and compressed air.

I can even supply the ferret (evil, bitey smelly little bastard that it is).

There must be a limit of how far you can push a flexible rod? We've got cable TV here and they seem to work on more like 100 yards max.

When the run gets a little too long, there are lubricants available that help reduce the friction. Anything soapy will do, essentially, but it makes _everything_ really slippery to handle, including of course the rods you're pushing down the conduits. Have one person down the hole with the lube & guiding the snake, while you stay up top hands clean & dry handling only clean & dry snake till it emerges out the other end.

It's not going to be easy, we normally install a pulling pit every 50-75 metres, plus one each side of a bend. If you have any bends in your 130m run, you're in deep trouble & blowing it through may be the only option, assuming the conduit is still reasonably clean (they never are)

We've got

horrible warning.'
