Broken screws

[CaMike]

Hi guys, been awhile since I was on the site, couldn't even remember what my old username was. Anyway I just acquired a Okuma Metaloid 5Nii and was working on Alan proofing the reel. When I went to remove the four screws on the reel seat, two broke off due to corrosion. When I removed the reel seat the screws are flush with the reel frame so I can't get ahold of anything. I used a punch and began to try and drill out a screw but my drill press is too big to do precise work like that, don't want to drill through the frame.

Anyone willing to help out?

Thanks,
Mike
