And while caution should be exercised while working on any firearm, the venerable Colt Single-Action may be the most prone to screwdriver dings. There are three different screw sizes on the Peacemaker and unless atlas you''ve got a screwdriver that truly fits the slots, the possibility of damage is real. Hardware store screwdrivers won''t do.Enter Bill Laughridge of Cylinder & Slide Shop. Handgunner readers know him as a custom gunsmith, but his operation also offers quite a few specialty parts. It turns out that Laughridge performs a lot of work on the old single-actions, so his specialized screwdrivers are based on practical experience.

The new Air Daddy makes it simple to inflate balls, air mattresses, swimming aids and other recreational equipment. Attach the threaded end to a portable air compressor, gas station hose or bicycle pump and the Air Daddy becomes a high-pressure air pump. Included are two adapters that are designed for small and large inflation holes. The ergonomic design makes it easy to grip in the palm of the hand. Sized to fit easily in small medical and lab equipment, fuel cells, and mass spectrometers, the tiny Model P5H7 scroll pump delivers up to 10 psi and has a no-load flow of 0.14 cfm. Quiet and inherently vibration-free, it is available in aluminum or economical injection-molded plastic. Pump can be adapted for liquids and is suitable for mini drill press use in disposable applications. the vilter mini-screw (vsm) is a rotary, positive-displacement compressor that incorporates a main screw and two gate rotors. the compact design has no external tubing, no gearbox, and an optional oil pump. in addition, the vsm is quieter than twin-screw compressors. champion offers the hgr6-3k reciprocating press air compressor model in the r series line. this engine driven, splash-lubricated compressor is a two-stage pump. the unit has been engineered with an integral cylinder head, which does not require head gaskets. this design eliminates the possibility of blown head gaskets. a 0.5-hp scroll atlas compressor/vacuum pump is an oil-free unit that provides less than 1 torr of vacuum or 20 psig of compressed air on ventilators, aspirators, oxygen concentrators, and blood-pressure monitors. the scroll design offers smooth, pulse-free operation, and with only one moving part, scroll machines usually last the lifetime hand drill press of the equipment in which they are integrated. single-stage compressor/vacuum pumps can be used in laboratories, electronics-manufacturing applications, and in the energy industry for fuel cells and microturbines. used as a vacuum source, the 0.5-hp unit provides < 1 torr ultimate vacuum with a pumping speed of 3.5 cfm. in compressor mode, the unit provides 3 cfm at 20 psig, with max open flow of 3.5 cfm. a four-pole ac motor powers the compressor/vacuum pump.

keith/u.s. tsubaki: the overall costs of a locking device must be balanced against the requirements of the application. keyless locking devices handle both high torque and thrust, while increasing shaft strength. they are not affected by torsional load reversal or impact, which can damage keys and keyway connections.jeff/tollok: one commonly mentioned advantage of keyless connections is that no secondary processes are necessary. the mechanical interference fit principle of a keyless locking assembly precludes having to cut keyways, tapers, splines, or threads. a press straight cut hub with a good surface finish by a machine tool is sufficient. assembly and disassembly atlas is easy and quick, and angular adjustments can be carried out on the spot. and because the connections are backlash free, you don''t need to compensate for mechanical inefficiencies elsewhere in your machine or controls system. it was a quiet tuesday morning, about is minutes before opening the shop doors. all the techs were busy performing their morning rituals -- drinking coffee, reading trade publications and oiling their air tools. without warning, our otherwise tranquil morning was interrupted by a horrendous screech of brakes as a late-model, metallic-blue bmw m3 slid into the service drive. steam was billowing out from underneath the engine compartment. the driver, a moderately dressed, thirty-something suburbanite, jumped out and opened the hood. instantly, a huge white drill cloud engulfed him and the entire front half of the press car. i fully expected that when the fog cleared, at least one of them would have vanished -- like a magician''s disappearing act.
