Cutting Worktops
 

I need to replace two sinks (kitchen and utility). Due to the new ones
being 30mm wider (front to back) than the existing ones I need to enlarge
the holes. I do not want to disturb the worktops and tiles so I would like
to cut them in situ(?). Has anybody ever done this and if so what is the
best method. I have a range of power tools but because of the distance from
the wall to the back of the sink I cannot get in with my router or jigsaw.
I have a Rotazip type tool that may do it but I don't think the cutters in
these things are up to cutting 40mm thick worktops. Can anybody offer any
advice or am I looking at a hand saw job?

TIA

John

Yep, I think it will be a hand job. A Rotozip type thing is not
going to be man enough for this, I don't think.

Is it too close at the back to get in a circular saw?

Hopefully the sink will cover any slight wanderings away for the line
though.

If you've got any longish straight bits to cut, you may be able to use an
angle grinder fitted with a circular saw blade. But take care - it ain't for
the faint hearted - and may chip the surface, beacuse you really need to cut
from the underside!

You could then finish off with a rotary file - or maybe with a multi-angle
drill bit such as Screwfix D86592 etc.

Have you got any spare bits of worktop to practise on?

When fitting a sink you end up with a 1" overlap so chipping is not an
issue, whats wrong with a jigsaw, with a blade that cuts on the upstroke?

I thought the OP was talking about fitting a sink, not ways of getting
a "Darwin Award"

Hi,

Some jigsaws allow the blade to be put in at 90° which would help you
get closer to the wall.

Or put a brand new 1.6mm cutting disk in the angle grinder and use it
to cut a series of slots in the edge of the worktop. Then use a chisel
to channel out the wood in between.

Another way would be to fix a piece of suitable sized wood between the
wall and the ledge on the worktop, and use a router horizontally with
the guide running along the top of the wood to rout out the edge of
the worktop. Very dangerous though!

cheers,
Pete.

My jigsaw has the facility to mount the blade sideways. The blade is closer
to the front than half he width of the machine, so this can get you a bit
closer. Would this be possible/helpful with your jigsaw?

Also you could use the router horizontally, although not right into the
corners.

Many thanks for all the replies. I would not like to try the methods
suggested in some of the replies!!. I think it's a hand job (Oooh Err
missus!)

Once again many thanks
