Downpipe removal....Snapped things....

[anutz]

thanks Paulfzs...


So its going ok, i have worked up to 5m diameter and 10mm depth...


I have stopped as i need to know


1. How deep do i go, i have no orignal studs to compare to
2. What diameter do i drill to, so i can then tap


I know the tap pitch i use depends on the rods i have, they are M6 from Screwfix but i need to measure the pitch etc


Thanks for your help ( all...)
