The flowchart starts by asking questions about the cast iron bed of your plane.I've chosen the bed as a starting point because it has many easily identifiable markings, and it probably wasn't replaced that often.: (1915-1960) Screw adjustable fence started with type 12. Type 16 &17 are Stanley notched rectangle trademarks.
This is Stanley's most famous and popular combination plane.
A combination plane is one that can be fitted with different irons, or cutters, as Stanley called them, and be adjusted for a particular cut.
I've converted some of the plane dating information found in Patrick Leach's Plane Type Study into an easy-to-use hypertext flowchart.
Hopefully by answering a few questions about your plane you can determine which type it is.
Some owners worked them so hard that they had to replace one or several parts.
Some simply put the wrong bit in the wrong place, some customised their tools to suit their needs - the possibilities for change are endless.
The plow has very substantial 1/4 inch thick cutters which is a design feature that was probably inherited from wooden plow planes which had thick, tapered blades.
In a wooden plane, the taper on the blade helps to keep the iron tight against the wedge - backwards force on the iron serves to tighten it.
This beautiful tool is our favorite plane in the collection.
The 41 was offered from 1872 to 1897, and was probably phased out in favor of the more versatile Stanley 45's.
From what I understand, when the adjustment screw was added, the knob was moved to the fence, right? David Hechel was recommended but there doesn't appear to be anything accessible on the WEB. Thanks for your help, Bob, it's a first impression if the search data says that the body, defined by attachments -designs in the casting-knob on the front end of the main body that is threaded directly on the casting threads(not drilled through with bolt and top nut)- requires an all metal fence and no rosewood.
