Jag BrushTM Makes More Patch Contact to Bore than Do Standard Jags, Part IV:
Effect of Bristle Flex
Los Angeles, CA — the flexibility of a Jag BrushTM bristle gives it a dynamic gap
clearance, and, in turn, a Jag BrushTM and patch combo presses more patch fabric
against the bore wall.
Their flexibility allows a Jag BrushTM bristles to be at a perpendicular or near
perpendicular orientation, and that is when the minimum gap clearance occurs. At
small clearance its bristles push patch fabric deeper in rifling, and deeper means
more patch fabric contacts the bore.
The small clearance means they can push 1-layer and 2-layer pleats along the patch
folded around the Jag BrushTM. The 1-layer and 2-layer pleats occur at the extremity
of the folded patch, where the corners of the patch reach furthest down the jag. A
standard jag cannot do it. A standard jag has gap clearances at its ribs that are
designed for pleats thicker than 1 or 2 layers. As a result, a Jag BrushTM pushes
more portions of the patch against the bore.
A standard jag often does not have ribs along its entire shaft. Typically it has a few
ribs near the tip, and then no ribs along the remainder of the jag’s thin shaft. Along
the surface where a standard jag has no ribs, there is no or little pressure against
the patch. On the other hand, a Jag BrushTM can press patch fabric along the entire
length of the brush since it has bristles all along its twisted wire stem.
A standard jag has recesses between ribs. At the recesses, there is no or little
pressure against a patch. On the other hand, a Jag BrushTM does not have
circumferential recesses where a patch is not pressed firmly into the bore wall. The
continuous helix of bristles of a Jag BrushTM presses a patch at every longitudinal
location.
