Live center

Just finished my first project, a live center with dual bearings in the head.
Any pointers for a beginner?

Awesome work! I just bought a good live center. I should have made one instead like you did.

I have a few questions:

1. What is the lip on the housing for?

2. How do you ensure a repeatable and precision fit between the MT taper and the live center axis? I don't see any way to do that without a register or something at the threaded connection.

3. Is that a hardened tip I see at the nose?
 
Sorry for the delayed response, Christmas and all. The lip has no purpose, as to the threaded part, it only threads in to that point and I have a set screw on the other side of it, it i have the corresponding mark on the shaft of the live center.
 
You might want to make a spare tip similar to the attached image. It will give you more room to get a tool holder/ insert closer to the work
