English-style Dovetailed Steel Infill Smoothing Plane - Machining dovetails on Sole - sole-l2.m, sole-r2.m

* sole-l2.m - infill smoothing plane - 9" A13 style
* Jim Yehle - Salt Lake City - Aug 2002
* Dovetails (double-splayed) at left edge of sole
*  First pass (sole-l1.m) made normal woodworking pins
*  This second prog adds 15-degree splay
* Stock is 3/16 thick; sides are 5/32
* (for 1/8 sides, umm . . . give me a minute)
* Held in vise, edge up, front to left
* Part zero is: x=0 at front,
*  y=0 at edge toward operator
*  z=-.1762 at bottom of prior sockets (accurate!)
* Use 1/2" 60-degree dovetail cutter
