I submit to you, a corn cob letter opener:
It wasn't all that difficult to turn, but I did learn a big lesson, you can't turn them wet! This cob has been drying about a year now, it worked great. To turn it you first cut it to blank size, then drill out the "pith". I glue in the tubes with CA glue, seems to work the best for corn cobs.
The stuff turns REALLY easy, but normally it comes out fuzzy. So once I get it within about a 1/16th of final dimensions, I will use some CA glue to firm it up. I cut off the CA glue and then use the BLO/CA finish, to fill in the gaps and give a nice shine.
Here is a close up of just the cob:
Thanks for looking, I enjoy your comments!
