Stanley 113 circular plane

Stanley 113 circular plane aka compass plane

offered 1877 - 1942

10" long with a 1 3/4" cutter.

Handy tool to work concave and convex surfaces on furniture, shop fittings and so on. In European countries these planes are often called boat planes but I doubt that they were of much use to a shipwright for building a boat.

Cutter and lever caps on later models are interchangeable with No 3 sized planes. However, the original 113 lever cap is slightly longer than a # 3 cap and it will interfere with the chip breaker in the smoother.
Potential problems: Cast iron handle on the back often missing or fixed. The original handle is secured by two screws in the later models and one screw in the earlier models i.e. the handles are not interchangeable between the early and the later types. When purchasing one of these planes make sure the handle is present and without fixes. Turn the adjuster knob both ways to check if the sole flexes to the full extent both ways. Clean soles are important.
Early models have a side wheel to adjust the depth of the cutter, solid in the first models and "four-holed" in the subsequent models
