Most frustrating DIY job you've ever done?

[Johnnytheboy]

I don't mean expensive/lengthy/boring, I mean the most fiddly three handed job you've ever done.

I've always known I couldn't be a plumber or a mechanic, as fiddly jobs in enclosed spaces are my idea of hell.

Tonight I tried to mend the pipe from my bath's overflow, which had come adrift. It was nominally a push fit connection between the socket behind the overflow and a flexible pipe, but for some reason it wouldn't stay in place. So my whizzo scheme was to secure a jubilee clip round the connection. However:

• the pipe had to be held in place or it came adrift
• ditto the jubilee clip, but doing so was a separate operation to holding the pipe
• space constraints mean the only way to access this was by lying next to the bath in a position where I couldn't see what I was doing, or easily use my left hand

So bearing all the above in mind, the simple act of marrying the screw in the clip with the screwdriver in my hand's tip was the single most frustrating DIY job I've ever done. I'm celebrating success with the largest glass of sherry anyone except Boris Yeltzin has ever drunk.
