19,000 RPM? Danger to the manifold.

Seems like you'd want some kinda shield there....pretty cool, though.

It's welded pretty solidly.

I think we are going to build a scattershield around the wheel, but more so to keep fingers out and for sound containment.

Now do that with a CAS.

When things spin at 19k rpm and they don't sound like an F1 car, it's a little depressing.

Right up until the welds crack due to vibration at ~19k. Cool test, but don't kid yourself about how safe that rig really is. I'd be sitting in the next room with a plexiglass shield and a wall in between me and the sensor.

Kudos, but un safe. extremely.

Maybe you did more balancing than we know of, but a weld? Jesus I thought it was bolted on, that's even worse if there wasn't any balancing.

Well that seems like something i would walk past and get my shirt hung in for sure. That thing needs a plexiglass box to cover it while in use.

It's a work in progress; the scatter shield is going to happen pretty soon. It's one of our off the shelf trigger wheels; they're designed to be dynamically balance as is; the welds may not be perfectly balanced though. That will be fixed in the final version of this.

Anybody here at the Virginia MegaMeet where Bruce demonstrated the wheel decoder - with a circular saw and one tooth cut off the blade?
