brass compression bands

I don't have a micrometer, or else I could probably figure this out on my own. Perhaps someone could help me out?

I am making a sliding dewshield assembly on my refractor project, and I want to have a brass compression band under a soft felt interface for clamping/releasing the dewshield.

Can someone tell me the thickness of the brass band that people like Astro-Physics use in their barlow eyepiece clamp, or Televue use?

I'm eyeballing it at 1/32nd inch or veryyy slightly smaller. I see McMaster has got 0.032 and 0.025 brass bands in stock, and wondering which one is better.

Thanks!
Mike

So I ordered 3 types from mcmaster.com...

1/4" by 1 foot, 0.064" thick -- WAYY TOO THICK
1/4" by 1 foot, 0.032" thick -- NOT IDEAL
1/4" by 1 foot, 0.025" thick -- PERFECT
