Here is another tip from Bill Granade. This one dovetails nicely with the preceding page on When the Pipe Sticks. The day before he sent it, Bill said he had been contacted by three home drillers with stuck pipes.
He said:
I wanted to send you my stuck pipe picture…..the chain works like the Chinese finger toy – the more you pull, the tighter it grips the pipe (it does take some adjustment to grip correctly)……it is very rare that a student gets a pipe stuck when they use my 3 pipe drilling technique with no drill bits…..just a 45 degree bevel on the 2 inch.
