Ive been woodworking for a few years mostly with power tools.  I'm
interested in some of the things  hand planes can do better than power
planing, jointing and sanding.  I would also like to be able to do
dovetails.   I'm interested in furniture making and have made only small
pieces to date.  I have an old plane that was my Grandpa's.  There are no
markings of any kind that I can tell.  It appears to be the size of a
smoothing plane 2" wide, 9" long, 1 3/4" width blade.  No adjustable frog
or depth knob or lateral lever.  No chip breaker.  The 'frog/sole/cheeks'
are one casting.  The Lever cap has a finger screw instead of a cam for
tension on the iron.  Should I try to use this tool?  Thanks alot and I
look forward to learning about hand tools.
