Talk:Carpenter pencil

Latest comment: 4 years ago by Eagledj in topic New images

I've subbed this to put into more natural English. Sounded almost like a translation.

Also carpenter's pencils, in the UK, US and Canada at least, are typically of elliptical cross-section, not rectangular. They are certainly not "flat"-- a piece of paper is flat.

How does its shape stop it blowing away? In fact an object with a circular cross-section is the least likely to blow away (just basic aerodynamics, that) — an elliptical pencil effectively will act as an aerofoil (though not a very good one).

The bit about being stronger really needs a citation. Bonding the graphite to the wood in a pencil is quite a feat-- in general the graphite is etched with acid, and very particular adhesives are used. To say "the plumbago is put in the wood" is very vague. While the general manufacture of pencils need not be covered here (pencil can do that), the claim it is stronger needs justification. In particular, if a particular softness or hardness of lead (graphite) is used then it should be stated-- as far as I can tell generally it is just about 1B or 2B hardness, if it were much harder it would be difficult to draw a line on timber, but conversely the softer a pencil's lead is the easier it will break if dropped.

Traditionally in European continentaly carpentry, the pencils are alsways red so they can be found in the sawdust if dropped. They are always oval in diameter as an oval pencil will not roll when put on a tilted surface. A skilled carpenter does not have a knife among his traditional tools, so the pencils is always sharpened with his bevelled-edged chisel. All these facts are taught within the first year of carpenter apprenticeship. — Preceding unsigned comment added by 62.157.59.136 (talk) 10:24, 20 May 2012 (UTC)Reply
