I really think I can put a 5/8" hole by heating pretty easy - I got a good bit of brass around of different calibers. Will a strip of duct tape work to seal the hole?

I suppose a scrap of copper or aluminum tubing would work as well. 

Duct tape tends to fall off over time. You might try foil tape, it can be found in the HVAC section of any hardware store, it's typically used for gas appliance venting and duct work. You could also hot glue a piece of plastic cut from the lid of a butter/cool whip/etc container over the hole.
