1930s cast iron downpipe fixings - what are they?

I've got the paint and render off the fixings and the heads seem to be domed, but no slot or other means of undoing the things. They are normally very large nail like fixings that are hammered into a wood plug that sits in a recess that is chiselled into the wall. Basically very difficult to remove. I think in the circumstance I would be looking at ways of getting the wood out via the same route it went in. I was thinking of a drain clearing rod pushed in from below, particularly as the cast iron pipe won't look right with the domed fixings removed. *If successful,* that method may result in a large piece of sodden hard wood emerging from the top of the pipe and crashing onto the bonce of the person below. So, maybe, it would be best to get someone up a ladder to lift it out, once the first bit emerges from the top. A drain rod would be far too stiff to go round the bend in the shoe. I've tried shoving plastic 22, 15 and 10mm pipe up - the 22 and 15 are too stiff, the 10 is too small and also gets snagged on the joints. I started using a multi-tool through the shoe opening to cut off 20mm sections but then realised it was a long piece of wood and would take hours. If you can see the bottom of the stick, is there any chance of dropping a weighted loop of string down from the top and out the bottom? If so, you could pass the loop under the cut off bottom of the stick and use the string to pull it back up. If the string isn't strong enough you could use it to pull through something stronger once you've got the loop to the bottom. Tim Somebody else suggested using the 10mm pipe to do something similar. I managed to get the 10mm pipe all the way down from the top and tried fitting a penny washer to a bolt and screwing it into the end of the pipe - close, but no banana. Tomorrow I'll try fabricating or turning a piece of something to attach to the pipe to lift the wood - this seems the best strategy. |

Maybe stick with the 10mm pipe idea for a minute, and perhaps there's something you can attach to the end that would keep the pipe more or less centred and would ride over the joints?Â* Something like a small water bottle firmly attached with the neck downwards. And the next question here would probably be: "how do I get a small plastic bottle out of a cast iron downpipe" ;-) Hence why I said "firmly attached". You bring it down to the shoe, and if necessary cut it into bits with your multi tool. It seems to me that you can discourage all suggestions, with a hearty sneer, or you can use them constructively to sort out what is, after all, your problem. I can assure you that I have no pieces of hardwood stuck in my downpipes. I'm always amazed that people here are so helpful, when the OP only gives out a tiny fraction of the information about his problem at the outset. I think you missed my "smiley" - all suggestions are welcomed and I will report back whatever works in the hope that it helps others Sorry, I was a bit bad-tempered yesterday! I hope you get this sorted out. |

Pass a length of small bore plastic heating pipe down the downpipe and out of the shoe at the bottom, rigidly attach a 40mm (ish) plywood disk with an 8mm bolt into the plastic pipe, pull pipe gently from the top (jiggling at appropriate moments and supplicating appropriate deities to ensure the disk doesn't get irretrievably stuck) to lift the offending piece of wood within reach of the hopper. The offending piece of wood was a surprisingly heavy length of oak beading, about 2m long and 20mm across. Thanks for the various responses and suggestions. Well done, that's a really ingenious result. I do like the idea of using relatively stiff pipe to maintain the collector disk roughly perpendicular to the axis. |
