I can get the brass rods (along the outside)
in 1/4. Or 5/16 so that part don't really matter. But the 1/4 would be very loose in the holes

The repo alum dome top I have. Is not drilled(yet) for the 10 rods
On the underside has 3 raised square tabs that I'm assuming where the marker rods would go
On my other pumps. The marker rods had a adjustment on top to take up any slack
This set up does not. If the cork gasket and glass measurements was not dead on. What's to keep from cracking glass or marker rods from falling over inside? Also no way to hold any in place to set the dome on
