I'm putting together some lab equipment, and I need a rubber stopper to fill the gap between a 1/2 OD tube and a 7/8 ID opening.
I've looked into lab supply houses and they seem to have stoppers in lots of different exterior sizes, but very few (and small) interior dimentions. Finally someone told me to just drill the thing out.
Drilling the stopper out works decently, but using my normal 118^ HSS drill bit, I get a surface finishing that is pretty crappy. I worry that the seal that I'm getting is poor.
Is there a better way?
