Does anyone know how the lead is put into a standard wooden pencil? Is it the sort of thing that can be done as a DIY woodturning project?

Brendan,
I think they are made in two halves, a groove is cut in both faces the "lead' is placed in the groove and then the halves are glued together.

Not sure it's the sort of thing you can do on a lathe

Just googled it - see here - http://science.howstuffworks.com/question4651.htm

Brendan,
I don't make round things out of square ones but I don't see why you couldn't make up blanks as the pen makers do and then turn them up after you have glued the halves together . I guess the trick would be sourcing the graphite cores.

Uness of course you buy a bunch of pencils, split 'em open, take the graphite core out and....then.....make .....some.....pencils???:rolleyes:

If you want the whole story try to get the book "The Pencil - A History of Design and Circumstance" by Henry Petroski. It is an interesting read.

"Leads" for mechanical drafting pencils used to be readily available from any office supply store. But that was in a previous life. Unknown if mechanical drafting pencils are still in regular use.

How about making a blank like a pen blank,insert a pencil with glue then turn it. You may have to sand off the paint first but should be doable. The new pencil will be a tad thicker than the original.

A few years ago my eldest got a pencil making kit from one of the aunts. Piece of lead and two half wooden pencil sides (?) anyway the idea was to glue them together. So I imagine you can get the leads somewhere. Of course you can get thin leads ie .5 and .7 mm from any stationer

043Turning up past newcastle sell a shop pencil kit here (http://www.043turning.com.au/index.php?_a=viewProd&productId=232) I can't remember if they sell the lead inserts but may - just saw them $4. You have to log in to see pricing

Penstate in the US also sell a shop pencil kit, you can buy thick lead for them here (http://www.pennstateind.com/store/PKSPCL1.html)

hear about the NASAA, they spent 5 billion developing a pen that would write upside down, in zero gravity and in space, the russians used a pencil...
