BRM's Flexible Honing, Surface Finishing, and Deburring Blog

BRM's Flexible Honing, Surface Finishing, and Deburring Blog is the place for conversation and discussion about how to solve difficult finishing problems. For over 50 years, Brush Research Manufacturing (BRM) has helped customers use brushing technology to clean, rebuild, and resurface components ranging from engine cylinders to brake rotors to flywheels to firearms. BRM's Blog on CR4 provides real-world examples of how flex hones and wire brushes work. It also evaluates related technologies and invites questions from the community.

Shotgun Cleaning, Polishing, and Maintenance

Posted January 27, 2014 3:25 PM by Brush Research

As hunters, target shooters, law enforcement personnel, and the firearms industry know, proper firearms maintenance is an important part of gun ownership. Moreover, as gunsmiths will attest, weapons that are properly cleaned, polished, and maintained will shoot more accurately and last longer.

Gun owners also know great shotgun tools don't require elaborate setups or special equipment. Built with a metal mounting stem, flexible honing tools from BRM are designed for use with a variable-speed electric drill, a type of power tool that most gunsmiths already own.

Flex-Hone technology is best known for its flexible nylon filaments and distinctive abrasive globules, however. Self-centering, self-aligning to the bore and self-compensating for wear, the Flex-Hone for Shotguns is also as easy-to-use, as this video explains.

Shotgun Barrel Hones

BRM's shotgun barrel hones improve the appearance of smoothbores and make shotgun barrels easier to maintain. By gently smoothing the metal, these Flex-Hone for Firearms tools create a more uniform surface that resists corrosion and wear while reducing fouling. Choose medium-grit and fine-grit barrel hones for 10, 12, 16, 20 and 28 gauge barrels or .410 bore. These shotgun barrel honing tools use silicon carbide (SC) or aluminum oxide (AO) abrasive.

For used shotgun barrels, use a medium-grit honing tool to remove rough and tight spots from the bore, and then a fine-grit hone to impart a final finish. With new shotgun barrels, a fine-grit tool is enough to produce a bright, mirror-like finish that improves resistance to corrosion, fouling, and wear. Whenever using shotgun barrel hones, insert the tool from the breech if possible. These flexible honing tools have a protective shrink tube coating on the stem wire.

Shotgun Chamber Hones

Shotgun chamber hones improve the surface finish of the chamber, the part of the shotgun where shells fit into the gun for firing. Although chamber lengths may vary, especially in old shotguns, all weapons require proper chamber maintenance. Unless this important firearms component is regularly cleaned after firing, residues may build-up and eventually cause the firearm to malfunction.

BRM's shotgun chamber hones have a 3" abrasive part, 12" overall length (OAL), and use fine-grit AO abrasive for an ultimate finish. Choose flexible honing tools for 10, 12, 16, 20, and 28 gauge shotguns or .410 bore. Like all Flex-Hone for Firearms tools, these gun hones are versatile, reliable, and easy-to-use. The final polish they provide also helps to reduce fouling, corrosion, and wear.

Shotgun Forcing Cone Hones

Shotgun forcing cone hones are tapered so that this Flex-Hone tool's abrasive globules gently smooth the surface of the funnel-shaped area between chamber and bore. If a shotgun's forcing cone has a flat rim or is too rough, the shot pattern may be adversely affected. Honing your shotgun forcing cone with the Flex-Hone for Firearms produces smoother shot constriction and less barrel fouling.

Brush Research supplies forcing cone hones for 12, 16, 20, and 28 gauge shotguns. Choose medium (180), fine (400), and ultra-fine (800) grit tools in SC abrasive. All shotgun forcing cone hones feature a 1-5/8" abrasive part and have an overall length (OAL) of 10". Use BRM Flex-Hone tools to put the finishing touches on these important firearms components.

This looks like a solution in search of a problem.

More like a high dollar cleaner/polisher.

Any discontinuities will still be there after this "polishing" operation.

No sale.

I was going to suggest that this be moved from 'Manufacturing' to 'Commercial Advertisements,' then I noticed that this was BRM posting in their own personal sub-forum, so it's right where it needs to be.

I guess it was my 'fault' for not noticing that the 'summary digest' email from CR4 includes a section for 'New Blog Entries' right under the 'Question and Answers' forum news.

It can get annoying to head to an Engineering site, expecting to find discussions on actual problems and practical solutions, only to find a collection of salesmen all screaming 'Buy my stuff! Buy my stuff!' However, since this was a case where I simply 'walked into the wrong room,' I will just metaphorically step back out and politely close the door.
