Is anyone aware of any way to measure the surface shear-force field (2D distribution of shear forces) created by an impinging fluid jet? As an analogy, think of shooting a garden hose at a wall, creating the circular flow pattern. I want to know (to some decent spatial resolution) the shear...

Great information - thanks all. I think I'll move forward with the Victrex PEEK, thread forming screws and/or inserts. Thanks for all the help. Cheers!

Thanks Pat & Pud - yes, this is a low volume medical application, so cost is not my primary consideration. I had a feeling I was asking a lot on this. I've been reading that PEEK seems to be better than Ultem in regards to cracking. Do either of you have any experience with tapped PEEK? I'm not...

I'm looking for an autoclavable resin that can be purchased in standard shapes (e.g. for billet-machining fabrication, not injection molding). However, I'd really like it to be able to take a threaded metal fastener (e.g. stainless steel screw) without cracking. It needs to be able to survive...

israelk: thanks for the reply. Permanent magnet or spring-applied failsafe brakes are pretty standard things. Very common on robot arms that have maintain their position even if the power fails - think "parking brake". There are many manufacturers of larger sizes, but I'm on the hunt for a...

Thanks Clyde38 - just by chance a colleague suggested Island to me today as well. I've contacted them via their website just now. Do you happen to know how small they go? Thanks! Bruce

Does anyone out there know of any "subminiature" spring-applied or permanent-magnet failsafe brakes? I'm looking for something to hold only about 0.04Nm (about 5.7 in-oz), and under 20-25mm diameter. Thoughts? Leads? Thanks, Bruce
