What is the purpose of the grooves found in the sole of some smoothing planes?

What is the purpose of the grooves found in the sole of some smoothing planes?

Description: A metallic plane having the sole grooved in lines parallel to the sides. Storke says this is to decrease the points of contact between the plane and work piece and to form free air-channels so that no vacuum can be formed.

Why do some planes have corrugated bottoms?

The corrugated sole was produced in Bailey pattern planes for a period with the intention of reducing the surface area of the sole to further reduce the friction of the plane on the surface being planed. Even flat soled planes do this.

How flat should a plane sole be?

The soles of our planes are machine ground flat and square to . 0015″ or better, regardless of length. This is exactly the tolerances specified by the the engineers who came up with the BS standard all those years ago, so I guess they knew what they were on about.

What is a plane sole?

A cutter that extends below the bottom surface, or sole, of the plane slices off shavings of wood. A large, flat sole on a plane guides the cutter to remove only the highest parts of an imperfect surface, until, after several passes, the surface is flat and smooth.

When did Stanley make corrugated bottom planes?

Introduced to the Stanley line of bench planes in 1898, corrugations were available on all sizes from the no. 2 through the no. 8, as well as the comparable sizes in the Bedrock series.

How long should a jointer plane be?

20 to 24 inches
Jointer planes are typically 20 to 24 inches (510 to 610 mm) long, and are the longest hand planes commonly used.

Where are Stanley planes made now?

China
These planes, made in China, have generated a lot of interest and debate on Knots, our online woodworking forum.

Can you use a jack plane as a jointer?

The most traditional way of setting up bench planes is to use a jack plane to remove material, a jointer plane to straighten it and a smoothing plane to prepare it for finishing.

How is the sole of a plane made?

Well over 60% of the sole was this self-oiling wood, which on its own would glide over the surface of a board like a swan on a lake. This aspect of the plane worked and worked well, the other parts didn’t.

What was the purpose of the corrugated sole?

It was an attempt ,like the corrugated sole, to help us woodworkers so that they could sell more planes ad we would have the burden of wood-grabbing surface-sucking planes lifted from us.

Why are corrugated soles worse than flat soles?

Even flat soled planes do this. The problem inherent to corrugated soles is the grab and mush up in the grooves and on subsequent forward thrusts, damage the surface you are supposed to be smoothing. No craftsman I ever knew favoured these planes.

Why did they use Bailey pattern corrugated soles?

The corrugated sole was produced in Bailey pattern planes for a period with the intention of reducing the surface area of the sole to further reduce the friction of the plane on the surface being planed.
