CIRCULAR PLANE
Short bowl-shaped cast housing with two left-sided wave housings, an overhang at the front with a threaded insert and 9 mm screw. The screw head is shaped like a sphere, 45 mm Ø, with a 10 mm left-hand thread on the outside and a 6 mm right-hand internal thread. Inside runs a rod, attached with two lugs to the front tilting rods, a 6 mm right-hand thread screw moves up and down with the 10 mm screw when turned. The housing is deeper at the rear, with two 6x9 mm slots in the sidewalls for the plane iron cap. Bottom with a dovetail cut across the full width. Sole made of 1 mm steel sheet, mouth: 4x45 mm, riveted 18 times on an iron wedge piece 16/18x57x6 mm, riveted into the cast body.

A 33 mm long casting strip is riveted inside the housing. Inside runs a pair of radius guide rods on the outside with synchronized teeth. The guide rods are 110 mm long, 3 mm thick, and 8 to 12 mm high, straight on both sides. They are connected to the sole and middle part with two hinges. The synchronized teeth of 3 mm sheet templates with 32 and 28 mm long segment teeth ensure the synchronized movement of the waves. These are still without the bending gauge.

The iron stop plate 43x107 mm is screwed into the housing. It carries a screwed-on cast handle at the top. As with the previous model, it only has an iron depth adjustment. A wheel Ø 39 mm, 4 mm wide with 4 holes, and a 50 mm long and 9 mm wide screw are turned down at the end, running laterally through the thin plate's right hole and guided at the top in a 6 mm hole in the iron stop plate. A slider 34x20x2 mm, externally inserted at a right angle, runs only 5 mm long with a 9 mm nut on the cast guide at 15 mm sideways. The oblique cam on the top (5x9 mm) engages into the 25° slanted slot of the height adjustment plate 29x61 mm. The guides on the stop plate run upwards by 8 mm and slide with the 15x16 hole in the lower part of the plane iron on the cap screw.

Iron cap: 45/57/20x83x0-8 mm with 9 mm thread and a 30 mm long screw with a beautifully decorated 28 mm Ø head.

Double iron: 44 mm

Cutting angle: 53°
