Planes.

Holtey Classic Handplanes - Group of Classic Planes. Bench plane bodies are fabricated by double dovetailing the cheeks to the sole. This method differs from the wooden dovetail joint in that it is possible when using metal, to slope the tails in both directions. The tails are peened to fill the sockets, a process akin to riveting, but stronger. Using three plates of metal to construct the body allows the cheeks to be made from bronze whilst retaining a hard wearing steel sole.

Unlike the planes of old with their steel cheeks, the use of different metals shows the dovetailing to advantage. Steel sided planes were prone to rust, particularly when marked by perspiration from the users' hands; bronze cheeks do not rust. The sole is lapped to obtain a long lasting flatness far superior to anything obtainable by surface grinding. The wood used for the infill is usually rosewood. The cheeks of the planes are riveted together by a pin passing through the wood infill. Unlike planes from the past a tubular spacer, through which the pin passes, is used between the cheeks. Therefore any shrinkage in the wood does not upset the metal body.

Lever Caps

The distinctive Holtey design lever caps are polished by hand and fitted with a square threaded screw with a knurled knob similar to those from the past.

Adjusters.
The adjusters are modelled on the Norris pattern, but are made to closer tolerances and are far more precise than the originals.

The picture to the right shows the adjuster used on my low angle planes (Shoulder, Chariot, Thumb and Bullnose) and the picture below shows the longer adjuster (in component form) used on the Panel, Jointers and Smoothing planes.

Holtey Classic Handplanes - Panel adjuster components

All the components for the adjusters are made in house, including the retaining washer for the turret. The base plates (below right) are milled rather than being stamped.

The pictures to the left show the two types of traveller or banjo made in the traditional Norris style. The banjos are made from a single piece of metal, including the engaging spigot on the low angle adjuster.

The threads - stem external and stem internal/Banjo are cut right handed giving differential motion between the stem and banjo. This results in less linear movement per degree of stem rotation and finer control of banjo position. The threads I use are 5/16" 26tpi RH brass thread male and 7/32" 40tpi ME RH, giving a differential of approximately 8 thou per revolution.

Norris used 5/16" RH 32tpi and 7/32" LH 40tpi threads, resulting in the stem and banjo moving in the same relative direction. A Norris adjuster will give approximately 56 thou of linear movement per revolution.

Having decided to use differential threads I made the thread on the stem slightly coarser than the Norris original. This brings the travel per degree of rotation or resolution UP to a level which I considered optimum and it also allows the adjuster knob sufficient movement, without colliding with the blade at extreme settings.

Adjuster knobs are hexagon broached, which is probably the most secure and positive fixing. The stem is index milled to produce the hexagon form and then peened. The pictures below show knurled knobs awaiting fitting and the finished product.
