Clifton No. 7 – Joint Plane

The Clifton No. 7 is a jointer designed to level long surfaces and ensure perfectly straight edges before gluing panels. With its long body and 60 mm wide iron, it allows for precise correction of irregularities and alignment of boards.

This type of planer is typically used in the final surface preparation phase, being especially useful for straightening long pieces and preparing joints for gluing.

Manufactured in Sheffield by Thomas Flinn & Co. under the Clifton brand, this planer combines traditional construction with high-precision machining, offering great stability and consistent performance.

Like other Clifton planes, it's practically ready to work right out of the box, although many woodworkers prefer to sharpen the iron before first use.

Construction and materials

The body and frame are made of high-quality gray cast iron, with all critical surfaces meticulously machined. The sole and sides are precision ground, ensuring stability and smooth gliding over wood.

The rear handle and front button are made of carefully shaped, sanded, and sealed walnut, providing comfort and control during work.

The cutting iron is produced from cryogenically treated O1 steel, hardened to 60–62 HRC . Approximately 3.8–3.9 mm thick , it offers high rigidity and stability during cutting. The one-piece counter-iron ensures a firm and effective clamping.

Several components are manufactured from polished brass and polished stainless steel , including screws and the adjustment wheel, ensuring durability and smooth operation over time.

Bedrock System

Clifton planes use a system based on the well-known Bedrock design, originally used in some of the older Stanley planes. In this system, the frog sits on a fully machined surface in the plane body, creating an extremely stable base for the cutting iron.

This design increases the overall rigidity, reduces vibrations, and allows for extremely controlled cuts.

Another advantage of this system is that it allows adjusting the planer jaw opening without disassembling the iron assembly , making it easier to fine-tune the tool according to the type of wood or the type of cut desired.
