Ways to Clamp Shaft
Ways to Clamp Shaft
(OP)
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!

McMaster Carr sells a 5/32" dia shaft collar (http://www.mcmaster.com/#shaft-collars/=fzlyx8)
which could be reamed and then chase the set screw threads with a tap. Use a nylon set screw (http://www.mcmaster.com/#set-screws/=fzlzwx)

I thought about drilling a collar to the right bore diameter but then i run into the problem of how i would attach the collar to the square aluminum square piece. Welding is out of the question...maybe glue, but that is pretty tacky. Ideally, the aluminum square would have a hole for the collar to fit inside (with a set screw access hole) but it doesn't seem possible to press fit the collar.
I feel like there has got to be a better way, this seems like a common obstacle that i am not seeing a common solution to.

If you are wedded to a mechanical solution then you have plenty of space for a custom designed collet.

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