It's more an actual guideline. 60 degrees is pretty steep, requiring very fast movement up and down and conflicting with the real challenge - keeping the hone from popping out the ends of the bore while still honing all the way to the ends.

A honing tool is generally used to refinish an imperfect cylinder bore so the piston rings seat properly. If you bored out the engine to a larger size, then this step is a must in order to get a fine finish that ensures good break-in and longevity of the engine. If you are replacing old parts, including the rotating stock inside the engine, this is also recommended for the same reasons. The new piston rings will go through a break-in process that scores the cylinder wall by just a fraction so that they become seated and sealed. If there is even a small score or blemish, the rings will not seal up and you will experience blow by. Which is oil in the exhaust and intake. This will only affect performance in a small way, but it may gum up the valve train eventually. If you inspected the cylinder sleeve, or wall and find even the slightest evidence that it is not perfect, it is worth going through the boring process. It is not that hard and does not take to long to do. It is worth your time to ensure 100% compression is aachieved

you dont really need a 60 degree hatch. And its almost impossible to do it by hand, the only guarantee to get the correct hatch is to have a machine shop.
If you do it with a ball hone you probably wont get the 60 degrees but it should work.

After watching some videos I found that the slower you go the lower the cross hatch the faster you go the higher. So i winged it and got a 60 degree cross hatch first try. Thanks for nothing everyone!
