OD of 1.25" sinktube blade holder

[Jedi Belinos]

My brother is making a saber as a project for a machining class he is currently taking. I need to know the OD of the 1.25" blade holder so that he can machine the ID of the hilt to match this. We are planning on using this as an insert inside a normal machined hilt to make things easier for him to do. Unless anybody has any other ideas. Thanks.

Just under 1.25"

They are suppose to be 1.205 but I would buy one first and measure it as the company didnt hold a very tight tolerance and they anodized them for some reason.
