A Jack Plane with a Rounded Sole


When getting ready inventory by hand, essentially the most helpful aircraft might be
the jack aircraft (typically known as the fore aircraft amongst joiners).
Its curved iron permits you to take away a exceptional quantity of
materials with each stroke.

I normally journey with a steel jack (an outdated Stanley No. 5)
as a result of it’s much less intimidating in a classroom than
demonstrating with a wooden-bodied aircraft. However I do have a
picket jack that I’ll use at residence for my very own work.

This week whereas in England, woodworker Richard Arnold confirmed me one in all
his 18th-century jacks that had a rounded sole that
matched the rounded iron.

He stated the aircraft is English and dates from the mid-1700s,
primarily based on its building particulars, together with its tote, which is
offset from the centerline of the picket inventory. The aircraft had
an Ibbotson iron with no chipbreaker.


Richard, who additionally collects instruments regarding joinery and sash
work, stated he has seen this rounded sole on early jacks earlier than,
although it isn’t widespread. The benefit of the form of the only
is that you need to use your complete iron, as a substitute of simply the small
bit that protrudes from a flat sole.

By tilting the aircraft, the nook of the iron will reduce.

I think about it additionally could be helpful for coping with the within
floor of a coopered door, amongst different issues.

Whereas I didn’t get to measure the radius of the curve, it
regarded just like the iron was curved with a typical radius (equivalent to
eight° or possibly a tad tighter).

Subsequent time I dig out my picket jack, I would make this
modification and provides it a go. Or maybe I’ll radius the only
of my metallic Stanley on an edge sander (it is a joke, Alf.
