yea i know it is going to be drippy brown madness in there when it is running, i thought i would just run it real low on oil (not really)
No direct experience with such animals, but a few ideas:
Not sure about clearance issues, but might the glass *look* better if it were mounted to the inside of the case?
Since you've got access to the Bridgeport, might be a worthy idea to hunt up a good quality O-ring (as mentioned elsewhere) of the appropriate size and machine a groove in the case between the opening and the mount screws to form a seat/seal. That'd go a long ways towards preventing that *drippy* issue.
Might also be an idea to fab up an aluminum ring to match the mount circumference and holes - it'll distribute the stress placed on the view plate when torquing down the bolts and aid any seal arrangement you come up with.
It'll certainly give you incentive to change your oil regularly - black goo getting slung all over the porthole will definitely get noticed at bike nights...
Best of luck - an interesting idea
