Brush
Research Manufacturing (BRM) bought a used 350 Chevy engine and tore it down. As
last week's blog entry and engine
teardown video explained, our junkyard find needed engine cleaning. The block
showed some light rust, and the cylinder walls required surface finishing. As a
full-line manufacturer of brushing tools, BRM put its products to the test. As
this week's blog entry and engine cleaning video explain, performance
starts with the finish - and the results speak for themselves.
Let's take a
closer look at the brush tools that are featured in our 350 Chevy
Engine Cleaning video. They aren't the only BRM products that we used for this project,
but our new video includes some great shots of copper center wire wheel
brushes, wire end brushes, toothbrush-style scratch brushes, and (of course) Flex-Hone tools. Not shown
in the video are abrasive nylon copper center wheel brushes, cylinder washing
brushes, abrasive nylon twisted-in-wire brushes, and the Flex-Hone for Rotors.
Copper
Center Wire Wheel Brushes
With the
engine teardown complete, the video starts with how BRM cleaned the V8 block
with copper
center wire wheel brushes. These small-diameter power brushes come in
several arbor-hole sizes and are ideal for mounting in handheld power tools.
Unlike larger-diameter brushes, BRM's copper center wheels don't push away from
the work surface. Wire wheel brushes are great for rust removal, and can have
either carbon steel or stainless steel filaments.
Wire End
Brushes
As the engine
cleaning video also shows, wire end
brushes are great for general block cleaning. BRM end brushes are available in solid,
knotted, and circular flared designs, and are used typically with a high-speed
handheld tool. These power brushes clean, blend, polish, deburr, and prepare
surfaces in small, tight, or hard-to-reach areas. Choose brushing tools with carbon
steel or stainless steel filaments, and the brush diameter that best suits your
application.
Toothbrush-Style
Scratch Brushes
BRM's engine
cleaning video also shows toothbrush-style scratch brushes for reaching small,
tight spaces. These hand scratch brushes are
available in several different widths and are ideal for hand deburring, thread
cleaning, and the removal of rust or corrosion. Toothbrush scrub brushing tools
are staple-set in wood or plastic, or molded in plastic. The bristles are made
of stainless steel, brass, nylon or natural filaments.
Flex-Hone
Tools
BRM
Flex-Hone tools are available for any type or size of cylinder. The 350 Chevy
Engine Cleaning video shows flexible cylinder hones in various sizes, and notes
that these ball hones come as small as 4-mm. Automotive engine applications
include valve lifter bores, coolant lines, valve guides, cam oil ports, cam
journals, and cam bearings. The BC Series Flex-Hone tools shown in the
video can also be used to surface finish brake and wheel cylinders.
GB Series Flex-Hone tools are used to surface finish, deburr, and deglaze
engine block cylinders or liners. Designed for bore diameters from 3-1/4" to
4-5/8" inch, these engine hones have an overall length of 13-1/2". Like BC
Series brush tools, GB Series flexible hones are available in a variety of
abrasive types and grit sizes. As the 350 Chevy Engine Cleaning Video shows, BRM ball hones can be mounted in
a handheld electric drill and impart the ideal cylinder wall surface
finish.
