Cheffy thanks for the offer I really appreciate it. I ended up finding something lying around. An old thin wide holed hex nut. I sanded off the corners and shined it up and it looks really good. It was a little bigger thand .25 but I wrapped some thread for a base above the cork and slid it on and epoxied it in place. I worked out suprisingly well.
Thanks again for the offer,
Janus
