cast iron again

[pauls]

dont know how i keep getting them

i take it i can strap boss into cast iron stack and cutting into it is with a normal hole saw and carefuly does it

Yes with a decent holesaw and some patience you will be able to drill ithe stack getting a decent seal is another thing tho.... scraping the paint off and a light smear of clear silicon usually does the job .

further to the cast iron stack there is a branch on it with a cap on it, i want to run a soil pipe into it any tips on getting the caps off

My preferred means of making a hole in a cast iron stack is with a Rotabroach fitted with a magnetic clamp.

What sort of cap?

Hemp and paste is far better for sealing onto cast iron than silicone.

if its caulked lead youll need a good sized blowlamp to melt the lead out takes a while just keep heating and digging the lead out with a screw driver til its all out and the yarn will start to burn then tap it of
youll go home smelling like a bombfire mmm i can smell it now
it may have been cemented on if it was capped later in which case its a hammer small chisel,drill or whatever to break it out
unusualy to be caped as branches were normally socket ended in which case its a plug

not sure i just looked up and noticed a cap over the branch and thought thats where i should be able to to run the soil into

ideal opportunity to quote for a new stack, first thing we do if theres a cast stack is advise a new stack extra work and all that.
unless its an old building they want to keep it
