So U don't use the 510 lid center post at all?????
Well that's something even more simple.
Well for using Ithaka old atty in Ody dripper
One need:
Ody 510 dripper base
JGG 510 lid without it's center post,while using Ithaka adjustable pin instead,for make contact,
Bypassing the 510 lid direct to JGG center post.
