The cylinder gap
(also known as undercut or clearance) can be adapted very precisely to different facestock and liner thicknesses, so that even with demanding applications and ultra-thin liners optimum die-cutting results are achieved.
They came with a feeler gauge that allowed owners to quickly determine the proper cylinder gap
each time they swapped barrels.
In order to prescribe an ideal range of cylinder gap
clearances, it is important to establish how the revolver is primarily intended to be used.
Very curious as to how much velocity the shorter barrel and cylinder gap
bled off I headed to the range with the BFR and my chronograph, with my No.
Unlike the Regioman, however, which prints 80,000 copies per hour by means of a two-around blanket cylinder turning against the one-around plate cylinder, Mainstream's one-around cylinders make 80,000 revolutions per hour owing to the absence of mechanical disturbance caused by a blanket cylinder gap
. On the Mainstream, the blanket is a cylinder or sleeve that slides in from the press' side (E&P, March 27, 1999, p.
This possibility is supported by earlier research conducted by Daimler-Benz AG of Stuttgart, Germany, in which a graphite piston with a smaller-than-normal cylinder gap
ran in a gasoline-fueled Mercedes-Benz 190E engine and produced 30 percent less hydrocarbon emissions.
Bobby then administered his Accuracy package, consisting of recutting the forcing cone to 11 degrees, followed by a polish and lapping of the barrel face, ensuring it's square, and lastly, setting cylinder gap
so barely any sunlight can be seen when you hold it up.
We .45 Auto fans offered dire predictions about 9mm revolver performance because of the 3.0-inch barrel, the barrel/ cylinder gap
, and a rifling pattern that should present more resistance to the bullet than that in most 9mm semiauto pistols.
Though traditionalists might look down at the two-piece barrel arrangement, the truth is that it results in a tighter cylinder gap
than many one-piece versions.
The .32 H&R pressure barrel is 5 inches long and has no cylinder gap
. In production revolvers with barrels 4 inches and less, velocities were expectedly lower; revolvers with longer barrels fared rather well.
It takes time to train this pistolsmith to properly screw in a barrel, get the front sight dead vertical, and the torque right, with the cylinder gap
The cylinder gap
between the rear of the barrel and the face of the cylinder is nice and tight, too.
