Jack Plane
The Jack plane is made of european beech and uses a 2-3/8in
Auburn Tool/Thisle Brand double iron made (which I got from Trevor
Robinson).
The throat uses the "traditional" design. However, I couldn't find
stock thick enough, so the plane is laminated from 3 pieces (the throat
was roughly pre-shaped before lamination, and then finished after
glue-up). The middle piece is 1 in thick, which matches the width
of the tote-mortise, so the mortise was also shaped before glue-up.
The finish is several coats of boiled linseed oil.
As a note, I found Perch and Lee's book on plane making
a great supplement to Whelan's book with regard to the
shaping and other details of the throat. This was especially
true in that, since I used only hand tools
I was able to avoid the adjustments to the throat that Whelan's use
of power tools necessitated. Finally, I would highly recommend
the sections on plane-making in Ken Robert's books to anyone
attempting to make a "traditional" plane for the first time.
