Triangle PatchTM Safer for Bore and Saves Time When Compared to Square or Round Patches
Los Angeles, CA — a Triangle PatchTM reduces rod bowing, requires less rod strokes, and makes it less likely for a patch to become stuck. A reduction of rod bowing was noticed by Eric Feldman, a gunsmith and former US Army armorer.
When a patch wraps around a cylindrical object, patch fabric wraps over itself to create multiple layers in the form of pleats. When a cleaning implement creates too much 5-layer pleating in a patch, the device and patch combo requires one to punch the rod to make the combo go down the bore, or even worse, it becomes stuck in the bore. In either case, one is likely to make the rod bow so much that it rubs against rifling, wearing it down, and possibly damaging it. If a rod cannot remove a stuck patch, then the need to use another tool risks damage to the bore by the other tool.
The notches in the sides of a Triangle PatchTM reduce the amount of thick 5-layer pleating in a patch as it wraps around a jag. Elimination of all or most 5-layer pleating results in a smooth passage, and a smooth passage equals less rod bowing.
On the other hand, square patches do not have notches, and the lack of notches causes square patches at standard sizes to form too much 5-layer pleating. Round patches at standard sizes can cause even thicker 7-layer pleating, and when used with standard jags, such a round patch will become stuck for certain.
Users often cut down square patches to make them fit inside a bore, and doing that means more time and work. A user experiments by cutting square patches into different sizes to match a particular jag or loop to a particular bore. The notches in the sides of a Triangle PatchTM make the need to alter the patch unlikely in order to make it fit correctly in a bore. It means less work. The notches also allow a Triangle PatchTM to fit snugly into bores of a caliber range wider than fit by a square or round patch.
Triangular patches clean faster than square ones because having one less radius makes them reach farther down a jag. The “faster” is due to the fact that reaching farther down a jag means more patch fabric is pushed against the bore.
A triangular cleaning patch is more cost efficient than a square one. More cost efficiency is due to the fact that the manufacture costs to make triangles and square of equal area is about the same. Same cost is due to the fact that material cost accounts for most of the cost of manufacture, and assigning equal areas makes their majority costs about the same. The fact that a triangle exposes more fabric to the bore for about the same cost as square, makes triangle more cost efficient. Once notches are added, the cost goes up a little, but the benefit goes up more than a little.
Since a Triangle PatchTM has a longer radius than a square one, a long jag is necessary to utilize the benefit. (See jag selection.) Since each Triangle PatchTM cleans with more patch fabric, less number of strokes is required to clean a bore. Less rod strokes saves time and requires less work and patches. The points made above are why Triangle PatchTM falls under our Cleaner FasterTM brand.
Below is an explanation about how a triangle exposes more fabric to the bore.
A patch radius is measured from the center to a corner. When wrapped around a jag, a patch radius stretches from jag tip to the farthest reach along and down the side of the jag. A triangle having a longer radius derives from basic geometry. We see that a triangle’s radius is 14% longer than a square's radius when we hold their areas equal.
Conceptually a triangle has a longer radius for same area because a triangle has one less radius than a square has. To accumulate the same area around the center and along one less radius, more of a triangle’s area must be located farther from its center.
As fabric is located farther from jag tip, there is less pleating. Since a triangle has a longer radius, it locates more fabric area farther away from the patch center or jag tip and into the region of less pleating. At that region, being at the patch's extremity, a triangle folds less fabric underneath as unused, and that means it has more fabric than square has as exposed 2-layer or 1-layer. For a square patch, since it has an extra radius, more area is located nearer to the center, and that results in more patch fabric lying underneath a pleat, which means not exposed and not used. .
