For a number of years now I
have been playing around with the design of an early 18th century jack
I have drawn inspiration from the planes
illustrated on the John Jennion trade card as these are the only clue as to what
form they may have taken.
This is because as yet no one has managed to find
an original example. The plane in the foreground is attempt number 1.
This was merely altered from a late 19th century
jack. I still use this plane for general duties, but I was never happy with it.
Mark 2, in the middle was a failure in my eyes.
I placed the tote well offset this time, and
reverted to a conventional open tote. Big mistake. I cant get on with it at all.
Back to the drawing board.
Mark 3 is now under production.
This time it will be a pure jack with a heavily
cambered single iron. I might even match the sole to the iron and camber that as
well. I have decided to shorten the stock from 17 to 14 inches, the same as the
single iron jack in the Seaton chest. The tote will be completely offset this
time, and radically different to anything I have done before.
