Griz, what are the concerns in working with corn cob. Is the material stable? After all, it isn't quite "wood."

Corn Cob is a very interesting and somewhat frustrating material to work with...
First of all what you really want is dried feed corn... I am lucky to live on a farm and we have an old chicken coop that has not seen a chicken in 30 yrs, but has a load of old corn cobs scattered about... that is what I use... 30+ yr old corn cobs.. you are not getting any drier than that...
The second problem is diameter of the inner core... if it is too big you don't get the pattern of the corn on the pen.. you get the core... so you need to look for thin cored cobs....
Next comes drilling the cobs so that you go dead center through the core so you get an even pattern when it is turned round
Then comes the turning... cobs are extremely chippy and don't cut like wood, so the tools need to be scary sharp and you need a light hand and even then you may blow a cob off the lathe...
Once you get close to the finished diameter, the cobs need to be soaked to get them hard enough to finish cut and sand....
Then comes finish cutting, sanding to 1000 grit and a lacquer finish that takes a week to cure before being buffed out and then the pen is assembled...
Almost sounds like it is not worth the work, until you see one close up and they are fantastic looking...
I only do corn cob pens now on special order because of the amount of work involved in getting on absolutley perfect... that and the fact that not everyone wants a pen made from cow feed.
