Edward Preston Plane No.12 Review By: I.Ball

Category: Old Jack Planes

Manufacturer: Edward Preston

Plane Type: Jack

Model No: 12


The Edward Preston jack plane number 12 is unique in design with no other planes matching this design.

The lever cap is a screw-on cap; the cap is secured with the use of a screw, it doesn't have a lever at the top of the cap to lever the cap to a tightened state as most other iron jack planes do.

The lever cap has the company name and place of manufacture advertised across it.

The blade depth adjuster is positioned above the lever cap on the end of a threaded rod. The adjuster is a wheel nut which locates into a slot in the blade. When the wheel nut is turned the blade moves upwards or downwards depending on the direction of the turning action, this in turn sets the blade depth.

The wooden handle and knob are positioned and designed to make handling the plane very easy and comfortable to use.

If closely looked at, it can be seen that the handle and knob are slightly different shaped to other jack planes such as those by Stanley and Record.

The Preston 12 has a lateral blade adjuster located behind the blade for moving the blade laterally by moving the adjuster left or right.

The number 12 was one of the first British made mass produced iron planes of the 20th century.

"Just stumbled across your website and an absolute treasure trove of information. I was recently given an old Stanley 110 block plane and wanted to know more about it. Your website told me everything I needed to know.

But there is so much more to read. I forsee me spending a lot of time just reading page after page. I can appreciate how much time this will have taken to put together.

I just wanted to let you know that your hard work is appreciated."
