Rfv-sense: "an object used to shape material being worked". Any object to shape any material? In fact I suspect this is an error and that the two other senses define "mandrel" sufficiently and non-misleadingly. --Hekaheka 09:13, 25 April 2011 (UTC)
- Indeed, I'd like to see citations like "a hammer is a mandrel", "a knife is a mandrel". But I second what you've said, I think this is just plain wrong. w:Mandrel copies our definitions. Mglovesfun (talk) 12:41, 25 April 2011 (UTC)
- In fact Wikipedia first read: "object used to shape machined work", limiting the sense to machining. It was then "copied" to Wiktionary in the current form and later copied back to Wikipedia. I believe that even the original Pedia definition was wrong. As far as I know mandrel is something that holds either the tool or the piece that is being worked with the tool, but it is not the tool. --Hekaheka 17:32, 25 April 2011 (UTC)
- Quite apart from the fact that we seem to be missing a basic meaning — metal rod, or (deprecated template usage) spindle — there is a bit of information tucked away in w:Tube bending#Mandrels that suggests usages may be based on particular applications. Here, the application is putting something in a pipe to support it so that it doesn't kink when you bend it, and it seems most anything that does this job can be called a mandrel - including sand! The information in this section appears to come from Todd, Robert H.; Allen, Dell K.; Alting, Leo (1994), Manufacturing Processes Reference Guide (1st ed.). — Pingkudimmi 13:46, 27 April 2011 (UTC)
- I have understood that not any rod or spindle is a mandrel, only one that is used for holding a workpiece or machining tool in its position during the machining process. For the second use you mention: this may be the one to which the rfv'ed sense refers. If that is correct we could combine the current senses #2, 3 and 4 into one and rewrite #1:
- A rod, spindle or similar part used to hold a workpiece or a machining tool in its position during machining.
- A part used as an aid for shaping a material, e.g. bending a pipe without creasing or kinking it.
- How does this sound? --Hekaheka 04:15, 2 May 2011 (UTC)

No comments in last five months - I assume my interpretation has been accepted as correct at least until someone comes up with better proposal. Proceeding to edit the entry.
