## **Flexible Cylinder Honing for Better Bore Finishing**

### **Get The Gold Book Technical Booklet**

How much do you really know about flexible cylinder honing? For example, do you understand why a cross-hatch finish promotes oil retention and piston ring seating? What have you learned about coarse vs. fine finishes, micro-finishes, and how to hone tapered cylinders? Have you compared flexible hones to rigid hones in terms of features, benefits and – most importantly - results? Fifty years ago, BRM released what’s known as the “Gold Book”, a technical publication about cylinder honing that became required reading at many automotive technical schools. Today, the highlights of this respected resource are available in shorter form. BRM’s “Gold Booklet” describes common practices in cylinder honing and offers suggestions and recommendations you can use. Ready to learn more? Download the Gold Booklet today.
