Making neat cuts in lathe and plaster ?

[bobasd]

what kind of "piping" do you propose to use? for what purpose?
if its water pipes you can use plastic pipes, and work from above and drop them down in the stud bay behind the P&L picking them up through a small hole near the floor or behind the skirting?

the most pain free method of cutting a chase in P&L is to use a small circular saw (Aldi do a cheap 85mm one) set shallow enough to cut only the P&L.
first drop two plumblines to mark the chase then cut the lines with a stanley knife and then use the saw - someone else can hold a vacuum to pick up the dust.

dont go bashing anything - laths can overlap and are held in with tacks ie. they are fragile.

2 X 22mm pipes and 2 X 15mm for the the boiler to be installed in loft. Unfortunately they will have to be copper as they will be less than 1m from the boiler when they come out the top of the wall.

Your method does make the most sense causing the least amount of disturbance to the rest of the P&L, I will give it a go thanks

your pipes will not "have to be copper" - simply stub out in Cu from the boiler ( 350mm to 400mm Cu stubs should be safe) then adapt to plastic, and run plastic all the way to the next stub out(s).

Must admit never heard of copper stub outs before, google not much help either
