If it's not one single piece of paper timber then using a hole saw shouldn't be too difficult?
We wanted to go through in one go rather than cut a bit, chip it out, cut a bit, chip it out etc.
We've already pruchased loads of bits and bobs and in the run-up to Christmas it's adding up, so I came here for for answers
We may need to just coughup and buy the larger hole saw
If it's 200mm or more thick I would imagine the first question would be "is it it OK to drill a hole that big through it?" For a timbers of that size it may well be weight bearing. Where is this 200mm thick piece of timber?
For joists, I thought the rule of thumb was not to notch more than a 1/8 of the width, or 1/2 if you drill on the centre of the width. (id check that)
It's more than one piece of timber.
It's above the external door from the kitchen on the side of the house. Essentially the kitchen needs an extractor fan put in to comply with building regulations.
Normally, we'd of expected a frame around the door, a gap of 20-30cm then the frame to the top floor, but this just appears to have multiple pieces of wood stuck in this gap.
