   I assume you mean handscrews...http://www.adjustableclamp.com/handscroll.htm

   Tighten both screws at the same time! I never cared for that type of clamp myself. I like these personally...http://www.wetzler.com/quick.shtml

   Those two types of clamps are made for different purposes.  The handscrews are designed to enable clamping of non-parallel surfaces, which an F-style clamp won't do very well.  They also spread the clamping pressure over a much wider area.  They're great for clamping a round object, I've found, and one handscrew can be clamped to a bench or drill-press table and serve as a stationary clamp to hold a workpiece.

   The F-clamps are designed to stay at a 90* angle and the clamping force is pretty concentrated.

   I've seen specific directions for how to work handscrews, but essentially it amounts to getting them close by grasping both handles and spinning around each other (rotating the hands forward like a cheer-leader with pom-poms, LOL!), and then adjusting just one screw for fine adjustment.  When clamping a parallel surface, it is necessary to twist both at the same time. forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)Another proud member of the  "I Rocked With ToolDoc Club" .... :>)

   PS:  Good idea to oil the threads, but don't get any on the faces of the clamps.

   Here's a picture of how well they work for angled stuff:

   I've found all sorts of other uses for them though.
