lifting T+G chipboard

[colin_h]

What is considered to be the least damaging method of taking up bits of a T+G chipboard floor?

I only need to get 1 board up in every room to run some pipework in. all I can think of is running a circular saw down one or both T+G joints and lifting but will this affect creaking and general movement when they are re-layed?

Thanks for any thoughts.

heeelllooo colin h
youve got the right idea
now the problem youve got is getting the depth spot on

too deep cut badly placed wires pipes ect too shallow
wont seperate the boards across the grain
cutting along the length doesnt matter as long as you
go within 2 mm of the depth it will either lift up cleanly
or break of the bit thats left
now because you cant slip the boards side ways
to clear the other tounge youll probably have
two sides loose

now if its under carpets wont matter to much
but if your floor boards are exposed might be worth
cutting both sides and putting a 6mm or7mm slither
in one side[thickness of the blade times two]
to fill the gap

and you wont get creaking if you nail into the same holes
[3mm gap from blade]
