Thought it was going to be a quick job today - plumbing in the drainage for a basin in our downstairs loo.
When I put in a new soil pipe in the summer I made sure I got one with an additional side boss. Today, armed with my hole cutter... I discovered the hole cutter isn't deep enough and bottoms out on the boss. No problem, get a normal drill bit and chain drill... except I'm drilling onto the outside of a curved surface, so I've left quite a few bits of plastic untouched. No problem, I'll get a chisel to finish off... and now I've cracked the boss!

I've had to find a pipe slighlt larger, araldite it over the top to form a collar, and tomorrow I'll stick the cracked bits back into the collar. Hopefully it'll seal OK, in the meantime it all smells of soil pipe, and we can't use the dishwasher or washing machine as they all go into the same soil pipe
