Looking for tool I can't find.
 
Maybe a stupid question. Is there a smaller tool that would act in the just opposite way to a clamp. A small "spreader" sort of like a jack but small enough to use on finer woodworking projects. Obviously I need some way to hold two boards apart temporarily and capable of rather precise and variable working lengths, so screwing or glueing can be done.

Nearly every quick-grip style clamp I've seen let's you reverse the jaws to be used as a spreader. Dunno about precise but its workable

If you have access to a drill press and a tap set - find a piece of bar stock, aluminum or brass, steel, whatever, size depending on how big a clamp needed. Example, aluminum bar stock 3/8" x 1/2", cut two pieces 2" long. Clamp together and drill through one end with a # 7 drill about 1/2" from one end. Separate the pieces, open the hole in one piece to 1/4", and tap the other with a 1/4-20 tap.

Cut a piece f 1/4-20 threaded rod about 4" (longer if necessary) long, and screw one end into the hole you just tapped in the one bar. Let it project out about 1/4", and tighten a hex nut against the bar. Add a hex nut to the other end of the threaded rod, then slip the other bar with the 1/4" hole over the rod. To use, insert the bars into the space you want push apart, then holding the bars in position, screw the nut towards the bar with the 1/4" hole, spreading the bars. To work well, the bar with the 1/4" hole must be thick enough that it can't tip on the rod.

Scale the sizes up or down as needed. By reversing the bar and nut on the end with the 1/4" hole, it works as a clamp also.

You could make a pair of cabinet jacks like these and use them as spreaders. I made a pair to use when removing and replacing our kitchen cabinets (uppers). They worked great.

Not my idea, but they are awesome.
Here are a few pics of mine in action.
Hope this helps.
