Draw wire through 130m duct

Similar to this? A bit pricey for a 1 off job but they must be available for hire somewhere.

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,

120m, about 20 quid for a weekend. Perfect.

[Stuart Noble]

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)
