In Detail

It is over 150 years since Leonard Bailey took out the patent for a metal-bodied plane. In this modern reinterpretation prolific inventor and designer, John Economaki of Bridge City Tool Works uses materials, production methods and tolerances unimaginable 150 years ago. To quote John “Good enough is not enough”. His attention to detail is phenomenal; every aspect of the HP-12 plane is there for a reason. That includes the shape, the material, the finish and the function.

This may be the only bench plane needed in the workshop. It comes with two blades, each with two edges; effectively the HP-12 is four planes in one. One blade has 30° and 35° bevels whilst the other has a 40° bevel at one end and a toothed edge at the other. Used bevel-up and bedded at 12° the HP-12 can be a low-angle plane for end grain, a standard smoothing plane, a high angle plane for difficult grain or a scrub plane for fast flattening. When located in the plane, the edge of the blade that is not in use, sits in a protective aluminium channel. The blades are 5.7mm thick and 50.8mm wide, hardened to 60-62 HRC from A2 tool steel, and lapped to a mirror finish, no flattening required.

The body measures 305mm long heel to toe. The sole of the HP-12 is 304-stainless steel, extremely flat and features an adjustable mouth also made from 304-stainless steel. The sides are CNC milled and anodised 360-aluminium. Each side is press-fit to the sole with dowel pins and retained with cap screws. The openings in the pierced sides of the plane allow minute lateral blade movement with the user’s fingertips as well as reducing the overall weight of the plane.

Rather than the traditional lever cap, the unique toggle blade locking system is fast, secure, pressure adjustable and allows for the use of double-edged blades. Simply pull the sculpted “D” lever and the entire blade retention mechanism swings out of the way to facilitate blade changes. There are no loose parts to mislay or get lost, the mechanism is an integral part of the plane.
The front tote is turned aluminium, bead blasted and anodised. The mushroom shape is particularly hand friendly. Threaded into the throat plate it allows precise adjustment of the mouth. The rear tote is investment cast 304 stainless steel with a highly polished curved surface. It feels great in the hand, and is perpendicular to the blade's edge directing the forward motion of the plane straight at the cutting edge.

Adjustment for the depth of cut is via a modified Norris mechanism with a 0.5mm thread-pitch lead-screw for super fine control. The lead screw sits in a solid brass split pivot nut, resulting in a backlash free mechanism that is adjustable by hand. Moving the lead screw knob left or right controls lateral blade alignment.

The HP-12 includes a pair of depth skids. Fitted on either side of the body they turn the HP-12 into a highly precise thicknesser. The depth skids allow accurate dimensioning of stock to within a tolerance of 0.05mm. The HP-12 Dual Angle Smoothing Plane does not include a guide fence by design. However, there are two little holes at the bottom of each skid allowing the attachment of a wooden fence to one or the other. The skids feature rounded soles, which not only reduce friction but also allow setting them at different depths for creating tapered stock (louvres).

The blade


All metal front and rear totes that fit nicely in both small and large hands. The front tote is mushroom-shaped and turned from aluminium before bead blasted and anodised black. The shape is more hand-friendly than the more common balloon-shaped tote. The rear tote is investment cast 304 stainless steel and the angle is perpendicular to the iron edge directing the forward motion of the plane straight at the cutting edge.

The blade

Two irons are included for a total of four distinctly different grind angles. The robust irons are a full two inches wide and are hardened to Rc 60-62 A2 tool steel. A scrub grind is included and designed to be used for quick cross-grain flattening or difficult grained stock. A blade guard is supplied to cover the edge that is not in use.

Unique blade locking mechanism
Adjustable mouth

Unique blade locking mechanism

Easy to use sculpted "D" lever allows for easy changing of blade.

Adjustable mouth

The iron is engaged to the depth adjuster via a pin nut attached to a 0.5mm thread pitch lead screw. One full revolution of the lead screw increases the depth of cut by 0.1mm.

Twelve-degree bed
Depth skids

Twelve-degree bed

This allows three angles of 42°, 47° and 60°.

Depth skids

By adding the supplied depth skids allows you to turn your block plane into a 2" thickness planer.
