Router Bit Shank Rust
I hadn't been in my shop for some time and when I pulled some of my router bits out of their storage tray I noted a lot of rust on their shanks. I can probably clean the rust off, and hopefully it will not effect the performance of the bits much.
The rust evedently was caused because my bit tray is made of unfinished Birch Plywood. The wood apparently absorbed moisture and caused the bits to rust while being stored.
I would suggest to everyone to either finish their bit tray holes, make the tray out of UHMW or some other kind of non absorbant material, or store their bits somewhere other than in an unfinished tray when not in use.
