Mark,

Here is what the hub looks like.
The bolt holes are yet to be drilled
and tapped.

The 1/4 inch dia. hardened and ground shaft will extend
out the flat side to keep the steel trigger wheel as close
to the router bearing as possible.

Jim is working on a second one.

It is going to be interesting what the ABS sensor
looks like  on my O-scope. I'll also try an RX8 CAS
sensor to see which one works the best.
