Flex-Hone® Tips for Speed and Stroke Rate

Posted by Team BRM on Dec 6, 2016 10:12:31 AM

Flex-Hone® tools impart the ideal surface finish to cylinder walls. Made in the USA by Brush Research Manufacturing (BRM), these flexible cylinder hones mount in most any rotating spindle.  Some users chuck BRM ball hones in a handheld electric drill. Others mount Flex-Hone® tools in a drill press, milling machine, or lathe. Flexible cylinder hones can be used with CNC equipment and industrial robots, too.    

No matter how you use them, Flex-Hone® tools come with some best practices. For example, enter and exit the bore while the ball hone is spinning. Slow down your RPMs to keep the tool cool. Don’t over-hone by stroking too much. Last week’s blog entry listed a total of ten tips. This week’s article takes a closer look at some best practices related to speed and stroke rate.

Fact or Fiction? Engine Hones for Nikasil Cylinders

Posted by Team BRM on Nov 16, 2016 4:17:53 PM

There are plenty of myths about high-performance engines. For example, some drivers claim that most engine wear happens at high speeds under tough racing conditions. In fact, the one or two seconds before full lubrication at startup is where most engine wear occurs. Similarly, some mechanics say that more zinc in your engine oil is always better. Yet too much zinc can interfere with friction modification.

There are some powerful myths about engine hones, too. Some mechanics say that you should never use BRM Flex-Hone® tools with Nikasil cylinders. “Never”, however, is incorrect. While it’s true that BRM’s engine hones are not recommended for all Nikasil cylinders, you can use aluminum oxide (AO) Flex-Hone® tools to deglaze some (but not all) non-ported Nikasil cylinders. 

So what kind of Nikasil cylinders are good candidates for flexible honing? Let's take a look.

High Performance Engines and Flex-Hone® Tools

Posted by Team BRM on Nov 7, 2016 2:05:05 PM

Piston rings are engine components that seal the combustion chamber, transfer heat from the pistons to the cylinder walls, and help regulate oil consumption. To promote engine power and performance, the piston rings and the cylinder wall must form a proper seal.  Otherwise, excessive “blow-by” can enter the crankcase. The results can range from power loss to engine damage. 

As Performance and Hotrod Business magazine explains, Flex-Hone® tools from Brush Research Manufacturing (BRM) help promote piston ring performance. In an article called “Rings True”, automotive writer Ed Sullivan describes how BRM’s flexible hones “allow for the fine-tuning of cylinder bores”, even in engine blocks made of harder metals that can make piston ring break-in challenging.

Brake Rotor Resurfacing

Posted by Team BRM on Oct 24, 2016 1:58:34 PM

Most brake rotors get resurfaced when old, worn brake pads are replaced. By the time a vehicle needs a brake job, the rotors may have grooves or areas of wear from the rubbing of the old pads. If a brake rotor has an uneven surface, the new pads won’t make contact with the rotor at the proper angle – and squeaking or squealing may result. Even with new OEM or aftermarket rotors, a factory finish that’s less than ideal may cause brake noise. 

To improve the surface finish of brake rotors, auto mechanics trust the Flex-Hone® for Rotors tool from Brush Research Manufacturing (BRM). Named an Undercar Digest Magazine Top Ten Tool for 8 years in a row, BRM’s rotor hone imparts a non-directional surface finish where “scratches” on the rotor’s surface extend in various directions. This “basket weave” finish doesn’t just help the new pads to seat properly. It lowers harmonic vibrations and reduces noise.
