Sorry guys been busy and didn’t see the tag, yes this is how all outsert components will be, the exceptions being one that has an undercut on the location where a center pin meets a square shoulder.
The question is why is this so?
Two reasons #1 tool nose radius’ are a thing. Yes you can create a perfectly sharp inside radius with tools but the reason why not to do that is covered in the next reason
#2 strength. If I create a sharp inside corner it will create a weak point in the system thus giving it a sharp location to snap off. The tool radius creates a stronger joint and doesn’t allow the component to snap off right at the end of the shaft
More info
Can you avoid this gap while installing?
Yep sure can, you can use a chamfer stone if it bothers you and nock off the sharp corner of the ID of the shaft and it will allow that gap to close.
How much will it close? Hard telling because the gap will always be there at some level.
Is it going to cause an issue?
The entire gap will be filled with epoxy if installed correctly and the epoxy joint will ultimately be stronger than the shaft will at that point anyway.
Long story short, the inside radius is there for a reason, the goal is to design and manufacture the strongest system we could. When installed correctly it will only make the system stronger. Use a chamfer stone or similar item if the gap bothers you enough and makes you feel better about the aesthetics.
I’ll try to be available more but we’re sitting down for Sunday dinner currently
