The medieval toolchest: the plane (part 3)

This post continues from the previous post on medieval planes from Northern Europe. The previous post discussed the planes with a toat, this post will concentrate on planes without a toat and Lapp-style planes. While there are more images of planes with a toat than that there are actual surviving planes, this is almost the other way around with planes without a toat, and certainly with lapp-style planes of which only excavated examples exist.



Joseph is carrying a basket with his tools while Jesus happily tugs at his cloak. In the tool basket a plane is visible (circle), but you can see only the sole. It could either be a plane with or without a toat. Other tools are a chisel, axe, brace, and an auger. Detail from the painting  'The Holy Family' by the Master of the Magdalena-legende. Koninklijk Museum voor Schone Kunsten, Antwerp, Belgium. 15th century.


Planes without a toat

Planes without a toat consist of one block in which the plane blade is set. There are no handles, to help to push the plane forward or to press the plane more firmly onto the wooden surface. There are some surviving examples of the 13th century, as well as from the late 15th century. The surviving examples are relatively small block planes. However, larger examples should have existed as well, as is shown on the miniature from the Hausbuch of the Landauer Zwolfbruderstiftung in Nuremberg, Germany.

Fridrich Punkauer  († 1571) on folio 45r of the Landauer Zwolfbruderstiftung in Nuremberg, Germany. He is working with a plane with a toat, while a large try plane can be seen next to the window.

One small plane was found in Bergen (Norway) and dated around 1248. It was made from taxus. It has a length of 15.7 cm, a width of 2.9 cm and the remarkable low height of 1.3 cm! Also remarkable is that this plane already had a grooved wedge; This is likely a necessity as a cross-pin held wedge would have weakened the plane to much.

 In France, a complete plane (except for the wedge) including the iron and the cross-pin was found in an submerged medieval village in the Lac le  Paladru near Charavines. The site became flooded in 1280, which makes it easy to date the plane. The plane is made from beech and 15.9 cm long, 6.4 cm wide and 4.2 cm high. The edges are rounded to have a more comfortable grip. The iron is set at an 27 degree angle, which is very low, suggesting that the plane was used as a low-angle block plane. The iron pin is set at mid-height, almost halfway the plane. The blade has a sharp triangular form, being much wider at the sharp end, much like the blades of medieval chisels. Another plane blade from the medieval period also has such a narrowing form, and one might wonder if this is the standard look of the medieval plane blade. (Then all the blades of our replica planes are likely wrong, but I do not feel the urge to change them).

but the looks are similar to the medieval  toat-less planes.Image from excavation database.

Late medieval block plane (1500) made from beech with an iron sole. The plane has a grooved wedge, but it is placement is wrong. As a consequence, the wedge is too thick and the gap to remove the shavings too small. The plane is 13 cm long. Image scanned from 'Die geschichte des Hobels' by J.M. Greber.

We have only one toat-less plane in our toolchest. This is a small plane bought at Deagrad tools, a blacksmith who makes tool for re-enactors.

Our plane has the blade at the front at an angle of 45 degrees. The plane is 32 cm long, 5 cm high and 2.5 cm wide. The blade is 12 mm wide.

Left: A piece of wood was sawn from the plane body in order to cut the hole for the blade. After that the wood was re-attached with help of 5 wooden dowels. In the middle is a wooden pin to hold the wedge. Wedge and plane blade are shown above the plane. Right: Top view of the plane.

Lapp-style planes

Lapp planes are only found in the high north of Europe, in Norway. Lapp planes are supposed to be developed from the 'bâtastrek' or boat-moulder used by the Vikings to work the mouldings on the edges of the planks forming the hull of their long-boats. The planes have a horizontal toat placed at the front of the plane. It is difficult to imagine that the toat helps the plane to move forward. Here it more seems more likely that the toat is used to push the plane down. No medieval images of this plane exist, but two medieval examples, shown below,  have been excavated.

This is a Lapp style plane with a horizontal toat found in Tonsberg, Norway and dating from 1250-1300. 
The plane bears a runic inscription of the owner, saying 'Arni owns'.

A medieval plane from Bergen, Norway. It is a very small plane and therefore designated as a toy. This plane has a grooved wedge. Like the other Norwegian plane the toat is projected forward. The other wooden object is not a part of the plane.

The medieval toolchest: the plane (part 2)

Long promised, and finally here: this post continues from the previous one on medieval planes, and will focus on the French, German and other planes of Northern Europe, as well as providing as much illustrative material as possible of medieval planes. We are especially lucky that John the Fearless, Duke of Burgundy, adopted the plane as his personal symbol. Due to this many images of planes are found decorating his clothes, buildings, coins, etc. Most of these are quite schematic, though you can get a general feel of the proportions of the planes.

As shown in part 1, the Italian style medieval planes had some typical characteristics, like the cut-out handles. The northern European planes also have some typical characteristic, and can roughly be divided into three groups: planes with a horn or toat, planes without any specific hand-grip, and Lapp-style planes. The planes of the Duke of Burgundy fall into the first group. This post will consider the planes with a toat, the other two groups are presented in the next post. Aside from these three groups, there are also some medieval planes that look more different and will be also discussed in a separate post.

The planes of John the Fearless

The personal emblem or motif of John the Fearless, Duke of Burgundy (1371-1419) the plane. He supposedly adopted this symbol to oppose his brother and rival Louis, Duke of Orleans, whose emblem was a ragged staff. John ordered his brother be assassinated, and as a consequence was slain a few years later by supporters of the (new) Duke of Orleans. The plane as his emblem was first used in January 1406. The Duke had ordered 311 'planes' as new years gifts from his gold smith Jehan Mousefroy: 77 rings with diamonds and planes, 78 gilded and 155 silver planes (coins?). The most expensive gold ring was for himself, decorated with diamond, pearl and ruby. The orders for the planes (rabot/rabos)  can be found in his household books:

A lui [Jehan Mousefroy, his personal goldsmith] le premier jour de janvier cccc et cinq [= 1406] [...] pour avoir fait xlviij anneaulx et en chacun annel assis un diamant en xlviij rabos et est chacun annel avec le diamenz du pris de vj escuz valent iijc xxiiij fl.

The ring was made in 1412 by the goldsmith Jean Nicolas. Musée du Louvre, Paris France.

Later more of these expensive planes are ordered by the goldsmith:

pour avoir fait ung rabot pour monseigneur de charrelois [the son of John the Fearless] garny dune esmeraude deux diamens une perle pendant en un annel ouquel avoit assis ung rubi et deux diamens et pesant v esterlins dor valent a lvii; file marc xxix s p pour lafaeon dudit rabot iii; frans x s.

The plane was used everywhere by John the Fearless: on coins, in architecture, in books he ordered to be made, such as Le livre de l’information des princes. Also, gowns and hoods are made with embroidered planes in gold on a background of red and black velvet. He commonly is seen in these costumes on paintings and book illuminations.

On of the three planes (on a wooden plank) with some shavings on folio 1 of Le livre de l’information des princes. The plane blade is set at a very low angle, and combined with the size looks to be a block plane.  Brussels, Belgium, KBR, Ms. 9475, dated 1408-1409. Also other folio's in this manuscript are profusely decorated with these planes in the margins. See e.g. 'Der Knotenstock ist abgehobelt!  - der Hobel als Sinnbild der Reformation bei Johann ohne Furcht, Herzog von Burgund' by S. Slanicka for  more examples.

From the same manuscript: John the Fearless sits on a bench with a red velvet cloth embroidered with gold planes. Also the banner at his back displays planes with a toat. Bibliotheque Nationale de France Manuscript 23279 folio 119. Around 1409-1410.

Some portraits of John the Fearless, Duke of Burgundy with a hood embroidered with planes or planes with shavings. I have found these images on internet and do not know if these are original medieval paintings of the duke or where the original resides. At the bottom right two drawings of planes found on a hood of John the Fearless.

Planes with a toat

The toat is an upright handhold or horn at the front of the plane, which helps to push the plane in its forward direction. Toats can (still) be found on planes of all sizes, from smoothing planes to large try planes, though it is most often depicted in medieval illustrations as a medium sized plane. The toat can be placed at the center of the plane block, but is also found placed asymmetrically on one side.

Two woodworkers from the Hausbuch of the Mendelschen Zwolfbruderstiftung in Nuremberg, Germany with smoothing plane with a toat. Left: Peter Screiner (1444) and right Paulus Weydmann (1542) Note that the toat of the right woodworker is placed asymmetrically.

The ladies in this book illumination have a plane with a toat as well as a hacksaw (bottom right).  'The pleading at the court of Reason' from 'The book of the Queen' by Christine de Pizan. Harleian MS 4431, folio 196v. British Library, London, UK. Dated 1410-1420. 

The above depicted plane has a striking resemblance with the original medieval plane shown below (and with most of John the Fearless). This is a plane from the late 14th century (between 1355 and 1380 - around the same time as the illuminations) excavated from a pit in the Hanse city of Greifswald, Germany in 2001. Bram found this small picture in a book this summer and as this plane is from exactly our re-enactment period, we contacted the author of the book chapter. He was very kind so send us some more information on this plane. The plane is made of beech and has a length of 20 cm and a height (without the toat) of 6.8-7.5 cm and a width of 8.4 cm. Height including the toat is 13.2 cm, the toat itself is approximately 11 cm long and has a diameter of 4.5-5 cm. The body of the plane curved at the toat end to a height of 2.3 cm, the edges of the plane are rounded off for easy holding. Remarkable is that the toat and the plane are one single piece of wood. The plane angle is very low, 20 degrees and the opening for the blade is 2.5 cm, the width available for the blade is 4.7 cm. Such a low angle makes it likely that this plane was used as a modern low-angle block plane. No wedge or plane blade was found with this plane. A square iron pin was set to hold the wedge and iron (at 3.7 cm height - 6.5 cm length from the end). We will certainly reconstruct this plane and add it to our collection of replica medieval planes.

 Side of a choir stall from the cloister in  Pöhlde, Germany, dated around 1280. Nowadays in the Niedersächsisches Landesmuseum, Hannover, Germany. Among the woodworking tools is a plane resting on the workbench. 

The plane of Karl Schreiner (1421) from the Hausbuch of the Mendelschen Zwolfbruderstiftung was used to make a replica. Our plane is made from beech and is used as a smoothing plane. It is 26 cm long, 5 cm high (14.5 with toat) and 9.5 cm wide, fitting a 5 cm plane blade. The blade is set at an 40 degrees angle. The asymmetrical toat on the left side is rather comfortable and does not affect the planing performance.

Our version of the plane from the Mendelschen Zwolfbruderstiftung. The edges of the plane are rounded to have a more comfortable handhold. The toat is fastened with two pins to the plane block.

During the end of the 15th century, planes with pin holding the wedge were replaced with versions having a grooved wedge. Such a wedge allows the pressure to be applied more evenly onto the (edge of the) plane plane. It also does not weaken the plane body by having a hole for the bolt. Planes with wedges did exist earlier than the 15th century.

The plane by Albrecht Durer originally from the Melancholica engraving (from 1514, here the version by Viollet le Duc is shown). The plane has a toat as well as a grooved wedge. Also, the plane is a bit ovally shaped.

A southern Europe plane variant with a toat

There is a large plane variant with a toat depicted in the late 15th century that looks a bit different. This try plane has a very big toat in front, an increased middle part - that hold the plane blade - and an end without any special features. The plane is most clearly shown in a miniature from Jean Bourdichon (1505-1510) depicting the holy family as a craftsman family. Another is found on a misericord in the choir stalls in Plasencia Cathedral, Spain and a misericord in the Musee the Cluny has a similar form, but seems to be missing the toat - it might be broken off or is hidden beneath the hand of the carpenter.

The carpenter is working with a try plane with a heightened middle part on a work bench. The toat could be broken off, or perhaps more placed to the middle of the plane. Dated 1500, Musee the Cluny, Paris, France.

Bram has re-created the large plane of the Bourdichon illumination, albeit as a smaller version in beech. His plane has the size of a (number 5) jack plane. The plane blade is a recycled old plane blade with a width of 4 cm.The blade is set at an angle of 45 degrees.

 The toat looks relatively large, but is very comfortable to the hand.

The bolt that holds the wedge is made of an African hardwood. 

The gerfschaaf

The gerfschaaf is a typical Dutch plane, which is whale formed and has a curly toat at the front.  The plane body also becomes smaller at the front. A gerfschaaf has been used for multiple tasks: with a small mouthed opening for smoothing, or with a wide mouth for rough work, like a scrub plane; but also rounded rounded (ship) forms existed for planing curved work. This plane had its medieval predecessors; perhaps the smaller plane shown by Bourdichon in his miniature could be such a predecessor (or the Greifswald plane). We have also made a replica of the small Bourdichon plane. The plane blade is set at a low angle (30 degrees) to be able to use it as a low angle block plane. The plane works fine, but, as you can see at the illumination and the photos of the replica, the bolt is set such that there is little room to clear the shavings.

 Our small 'Bourchichon' plane or a medieval gerfschaaf made in beech. It has a length of 19 cm, a height of 5.5 cm ( 7.5 with toat) and a width of 6 cm - decreasing to 4 cm at the front.

Left: I made the mouth of the plane too wide in the beginning and had to make an insert to make it smaller. You can see very clearly that the plane is smaller at the front. Right: The (recycled) plane blade is thicker at the cutting end and consists of two layers of steel. Originally it was too long and had to be cut in half.

 The room for clearing the shavings is very small. The plane regularly has to be emptied by hand.

We also own some antique (beech) gerfschaven with grooved wedges. Images of gerfschaven can be found in the late 16th century. They keep this form until they become obsolete in the early 20th century. Our gerfschaaf has a length of 15 cm, a maximum width of 5 cm, and a height of 6-6.5 cm. Including the wedge and blade, the height becomes 11.5 cm. The blade is set at an angle of 50 degrees. The opening is wider than the Bourdichon plane and easily clears the shavings.

Left: The whale form of the gerfschaaf. Right: Here you can see that the plane becomes smaller at the front, but also a bit  at the back.
