Ways to Clamp Shaft

[engrwpride]

I need a way to fix a 0.160" diameter shaft into a 1/8" x 1/2" x 1/2" hunk of aluminum. The shaft cannot be damaged with a set screw and I would rather not rely on the elastic deformation of the aluminum block with a slot for displacement of the aluminum material. The shaft needs to be easily removable and re-clamped. This is to hold a probe in a wind tunnel so the less intrusive the method of clamping is the better.

Do you all have any suggestions? I am at a loss for ideas.

Thank you!

Thank you for all your help and patience.

The solution would be to just use a slim collar with a nylon tipped set-screw.
