Power-to-weight ratio. Ask mini drill press a tradesperson for an opinion about a power tool and you''re press likely to hear how powerful it jig is for its weight. most of us want as much power as we can plans get for the weight we carry. it''s easy to feel the difference between the most powerful and the least powerful drills, but it''s harder to judge power in relation to weight. i calculated power-to-weight ratios by dividing each tool''s torque rating by its weight. that allowed me to compare drills on the basis of inch-pounds of torque per pound of weight. drill i used the press manufacturer''s torque specs but weighed the tools myself.

* transfer pumps -- the majority of transfer jig pumps are of the diaphragm type that provide a maximum of 8 psi to the main pump. the diaphragm pump is plans simple in nature and usually trouble-free. however, drill the check valves may become sticky if the diesel fuel gets too old. fungus and bacteria can press gum up the valves and reduce both flow and pressure. also, diaphragms can rupture, and fuel can leak into jig the engine oil. this can be detected during plans daily service checks. drill and press on an engine that consumes oil, oil consumption would jig appear plans to stop and the oil level might even rise on the dipstick.
