cutting chip board floors and pipe/cable detector

[tuckermot]

I am going to be cutting some chip board floors with my circular saw and to be honest when working on domestic propertys i have a total
fear of cutting through pipes/cables underneath,even after setting the circular saw.I want to purchase a second hand detector and the ones i have had in the past have been about as reliable as draper drill any got any tips and recomend a 2nd hand detector to get of ebay

you could always set the circular saw depth, the same as the thickness of the chipboard.
that way you'll go over the pipes and cables without damaging anything

Hi supersparxs

i will do just that and then just lightly finish the cut with my floorboard saw but i still worry

how do you deal with floor boards when you are rewiring or just pulling a new feed cable through do you just cut circular holes each side of the joist you are trying to get through ?

Circular saw set just a touch under the depth of the board, then break the last mm off.

Hi

A circular hole in the floor board?

Hi imago

the title of the post thread states chipboard, I assume he is referring to newer, chipboard installs with large sheets of flooring. Not tongue & groove floorboard.

In which case, no, I would lift a section of board :laugh:

yes i am talking about loft boards ( chipboard )

so you lift floorboards if you want to gain access yes

for chipboard floors richard.....a large holesaw...then a 'bearer' in order to fix back.......or you can get a holecutter from armeg that cuts a shoulder into the chipboard....then you fit a plastic access plate into the hole when you'v finished......only thing is though ...is those access plates arn't cheap......

Im with spartykus, Lift the whole sheet. That way you only have to set the depth to cut the tongue off and no chance of touching pipes. It goes back better when you have finished also. I also keep some old wornout screwdrivers to punch the nails down or use a small 10mm core cutter on the screws that wont budge or lost their heads.

Same here.... and surround with bead of gripfill (or similar)

screws that wont budge......we just get the rattler on em......they soon budge then....

Have found some that have got wet and rusted the head and just round off but as you say the impact driver sorts most.
I still dont understand the builders that still use nails on them, thats not the gun type but plain hammer jobbies. It makes them squeek like f###
