Porsche Wheel Cylinder Rebuilds with Flex-Hone® Tools

Posted by Team BRM on Feb 19, 2018 11:31:52 AM

Porsche wheel cylinders support braking in sportscars that pack plenty of power. In classic cars like the Porsche 356, these cylinders have pistons that are connected to brake shoes. If a wheel cylinder lacks the right surface finish, however, more than just piston ring sealing can suffer.       

At the Porsche 356 Registry, an on-line community, the owner of a Porsche 356B asked for advice about honing brake cylinders. A few users suggested honing stones, but a German mechanic recommended the Flex-Hone® tool from Brush Research Manufacturing (BRM).

“I use this tool,” the Porsche mechanic explained. “This works better than all others.”

Honda D-Series Engine Rebuilds with Flex-Hone® Tools

Posted by Team BRM on Feb 12, 2018 2:50:16 PM

Honda D-series engines once powered compact cars like the Honda Civic. These four-cylinder aluminum engines were fuel-efficient and lightweight, but could be modified with high-compression pistons for increased power and performance.

At D-series.org, an on-line community for Honda enthusiasts, the owner of 1991 Honda Civic explained how he bought a 1.5L D-Series engine after the original powerplant “died”. The engine rebuilder inspected each cylinder and then asked for advice.

“Everyone said that good honing will take care of the rust and anything else left in the bore,” he said. To finish the cylinder walls, the DIYer used the BRM Flex-Hone® tool. The mechanic admitted he “had some doubts” about flexible cylinder honing, but using the tool made him a believer.

Rebuilding an International 7.3L IDI Engine with Flex-Hone® Tools

Posted by Team BRM on Feb 5, 2018 10:34:30 AM

Diesel Power magazine provides professional diesel mechanics with in-depth examples of engine rebuilds. Do-it-yourselfers (DIYers) also read the world’s largest diesel magazine for tips, techniques, and recommendations about engine tool selection and use.

In an article entitled Rebuilding International’s 7.3L IDI Engine Heads and Crank, Diesel Power described what the author called “the key” to a good engine rebuild – the Flex-Hone® tool from Brush Research Manufacturing (BRM). These flexible cylinder hones impart an oil-retaining surface finish that promotes piston ring seating and sealing in big diesel engines like the International IDI.

Suzuki GS-550 Engine Rebuilds with Flex-Hone® Tools

Posted by Team BRM on Jan 29, 2018 10:06:17 AM

Suzuki GS-550 motorcycles first hit the roads over 40 years ago. The bike’s original four-stroke engine was an air-cooled, 549-cc powerplant with dual overhead camshafts. The 674-cc Suzuki GS-650 eventually replaced the GS-550, but some bikers are still rebuilding Suzuki’s original engine blocks.

At Do the Ton, an on-line forum for motorcycle mechanics, a user described a GS-550 engine teardown and rebuild. Cylinder resizing requires rigid honing, but achieving an ideal final finish means using Flex-Hone® tools from Brush Research Manufacturing (BRM).

Maintaining M1911 and M1917 Handguns with Flex-Hone® for Firearms Tools

Posted by Heather Jones on Jan 22, 2018 9:08:01 AM

Handgun maintenance helps keep revolvers and pistols at peak performance. Handgun cylinders need a smooth, clean finish that’s free from build-ups of primer, gun powder, and ammunition casing materials. Tool marks that can promote fouling and corrosion also require removal.  

Flex-Hone® for Firearms tools remove surface irregularities and impart a surface finish that holds lubrication better. Smoother, cleaner cylinders are less prone to misfeeds, stove pipes, and misfires. Plus, BRM's gun tools keep the bores of your firearms at the precise dimensions required. 

How can Flex-Hone® for Firearms tools help solve your handgun maintenance challenges? As owners of M1911 and M1917 handguns attest, flexible honing gets great results.

GUNS Magazine contains expert articles about firearms selection and performance. Since 1955, readers of this monthly newsstand publication have enjoyed trusted content about the best guns and gun tools. Today, the magazine’s digital version also attracts shooters who want solutions to gun maintenance challenges.   

In an on-line article called AR-15 Building Tools Part II, author Glen Zediker describes some “handy” tools for gun owners who want to build or maintain their own rifles. “I think it’s important to polish the chamber on any AR-15”, Zediker writes. For smoother extractions, he adds, “I like the Flex-Hone tool.”

Resurfacing Slotted Brake Rotors with Flex-Hone® TOOLS

Posted by Heather Jones on Jan 9, 2018 12:40:09 PM

Slotted brake rotors contain machined grooves that help dissipate the heat that’s produced by braking. In racing, motorsports, and even regular driving, friction causes a layer of gas and dust to form between the brake pad and the brake rotor. Over time, this material transfer layer can impede performance. 

Slotted rotors help to reduce friction, but surface contact between pads and rotors eventually requires rotor resurfacing. For optimum brake performance, brake rotors require a non-directional or “basket weave” finish that’s free from deposits of brake pad material. 

To achieve this ideal finish, a do-it-yourself (DIY) mechanic recently tried the Flex-Hone® for Rotors tool from Brush Research Manufacturing (BRM). The racer who requested the resurfacing hadn’t heard of BRM’s rotor hone before, but the mechanic who used the tool gave it a thumbs-up.

Solving Shotgun Extractor Problems with Flex-Hone® for Firearms Tools

Posted by Team BRM on Jan 2, 2018 9:54:32 AM

Members of the Guns group on Reddit exchange information about firearms tools and performance. In a thread called This is the worst gun in my collection, several users cited the Remington Model 870 for shotgun extractor problems.

 “It doesn’t feed right at all,” said one shooter. “The shell gets stuck in the chamber after it’s been fired,” replied another. The M870 is the world’s best-selling shotgun, so these reports might surprise some gun owners. As Flex-Hone® for Firearms users know, however, the solution starts with the surface finish.

Knife Manufacturing with NamPower Disc Brushes

Posted by Team BRM on Dec 18, 2017 10:17:20 AM

Zodiac Engineering manufactures folding and fixed-blade knives. The Southern California startup also provides milling, turning, heat treating, tumbling, and precision CNC machining services. Zodiac’s founder, Ken Spaulding, makes aluminum and titanium sling shots, too.

With knife manufacturing, imparting the ideal surface finish is especially important. Customers don’t want to see tool paths and marks that are left behind by machining operations. Chamfer tools can deburr and surface finish the pockets in a metal knife frame, but the work time-consuming.   

That’s why Zodiac switched to NamPower disc brushes from Brush Research Manufacturing (BRM). These nylon abrasive brushing tools are fast, cost-effective, and long-lasting. NamPower technology is also the surface finishing solution of choice for Balzano Knives, a maker of high-quality knives and other bladed tools.
