Jetworks, tapping the pipe
I have never tried to thread something my self. How do I do this? Should I just take it to a local machine shop?
I am doing the fercho method!

It cost all of $7.50 a hole to do over at my local Napa. Make sure you have the correct size for the side opposite the waterbox. One of the Fercho drawings show it incorrectly

first mark out with center dot/punch where hole to be located..
small pilot drill to keep central say 3mm on the 1/8 npt thread..
them drill out to drill size for thread..
counter sink a small area on top of hole to be tapped to locate tap better and aid straightness..
start with first tap and end with plug tap,keeping tap straight with a good ammount of cutting compound (trefolex) ect..
go slow and a good rule of thumb one turn in, two turns out to clear swarf..
if in the water jacket a plug thread starts to far up tap (as npt is tapered) butcher/grind tap down to get full thread taper before hitting the innner wall..
explain to work why tap butchered as your working on jet ski...
