    This is probably a stupd question. I have a strap on boss for tapping into the plastic soil stack. How do I cut a hole without the bit cut out falling in? I've got a hole cutting wotsit somewhere for me drill. Does that always retain the cut out part?

    Yes. Even if it escapes from the hole saw, it stays impaled on the pilot drill.

    coolio. thanks. One more REALLY stupid question. For a hole for 32mm pipe, do I use a 32mm hole cutter or would this be too good a fit? Should I go to 35mm instead, and if so would the strap on boss take up the slack? Either way, do I need to seal around the new pipe wit summat?

    Yeas it is a stupid question :D :LOL: :D
    Buy the boss and all will be revealed.
    The Terrain ones are MUCH neater, imho - no strap just a clever boss.

    It wouldn't fit at all, because 32mm is its inside diameter.

    Yes you should, and there will be no "slack".

    What? :confused:

    When using a 32mm strap on boss I usually drill the hole at 50mm. The inner surface of the boss protrudes from the boss and is larger, so this needs to be accomodated in the hole. Solvent weld to fix it in place.

    Don't know the type Chris has stated.

    As the man said, obvious when you actually get one. All sorted now, thank you all.
