Ciselering - repoussé

Det engelska ordet för tekniken drivning (båda sorters) är chasing, och även här gör sammanhanget det tydligt vad man syftar på

Vid närmare eftertanke så tror jag att teknikerna att driva (upp en skål och driva med puns inom ciseleringsteknikerna) snarare heter raising.
Chasing kan kanske översättas med ciselering eller mer specifikt skrodning, att med puns forma linjer i plåtens yta.

Jag vet att terminologin i Sverige är förvirrad, vilket har sin orsak i de olika språk som påverkat den genom århundradena. Än idag finns ofta skillnader i specifika ords betydelser som ofta har att göra med var i Sverige smeden är utbildad och verksam. Inte ens de yrkesverksamma är överrens.

Vi hade också lite problem med terminologin när jag studerade på Leksands fhsk, eftersom vi inte använde samma termer när jag läste på Hellidens fhsk.

men då beslutade vi oss gemensamt för att följa termerna som Staffan Nilsson använder i sin bok ´silversmide´ eftersom det är den senaste och mest heltäckande boken om silversmide på svenska. Det blev lite blädrandes i början, men sen så flöt det på.

Just nu är alla böcker i flyttlådor, men kan kolla det när jag har packat upp dem, om ingen annan hinner före mig.

Ja God dag god dag,

Det har varit flera år innan jag besök att skriva på svenska.

So you get English. If I throw something at you, you don't understand, speak up.

Working sheet metal is kind of fun. The techniques are pretty much the same from large work to small work but the tools get larger.
Jewelers talk about repousse and chasing, as noted repousse comes from French pushed from behind.
the two are seldom far apart. And the term repousse usually incorporates chasing. Chasing also can mean carving the surface which a blacksmith does, but which is very limited in repousse because there just isn't much there to carve, it is mainly bent, drawn out, or upset instead.
Repousse can be done over pitch, but it is also done over stakes, and can be done over anything that supports the metal in one spot so it can be moved in another. I use stakes, wood/plastic blocks, sandbags, and plasticine clay a lot. reserving the use of pitch for fine detail.
At the other end of the scale you have Auto body men. These guys are going to talk about shrinking and stretching metal to achieve (make) shape and position. These concepts are also used in repousse.
Shrinking and raising (repousse term) are both terms that mean upsetting the metal (blacksmiths term), that is pushing it back into itself. It makes the sheet metal thicker in that spot.
Stretching, sinking, and usually planishing are terms that mean drawing out the metal.
Embossing, and debossing (pushed up from the sheet and pushed down into the sheet) are processes usually associated with press work. In other words where a sheet is formed over a pattern with pressure all at one go. They are also used to describe work whether it was done by machine or hand. (pushed. up/down)
Repousse and metalforming in a body shop are point deformation processes. That is you move just one bit at a time as opposed to presswork where the whole sheet is deformed.

I'd talk more but I have to get out of here. I am off for a 4 day Metalmeet (automotive scale work)
To learn more about this I would suggest http://www.metalmeet.com One of the board members is a Dane, and there are several posters from Norway and Sweden so if you run into strange terms there is somebody who can translate.

Hej då,
