I put a t2 fence on my r4511. I mounted it with the first and third holes on the fence rail. I’m trying to figure out what to do with the ground strap.

for those who have upgraded the fence on the r4511 what did you do with the ground strap?

Why is there a ground strap? This is for the fence?

There is a ground strap between the saw body and the fence, because it has a granite top, so there would be no other ground to the saw body otherwise (the switch, which is grounded, attaches to the fence rail).

When I put an Incra fence on my R4511, I just created a short 14 GA wire with crimp-on ring connectors to ground the body to the fence rail (with power switch attached). I used the same bolt that was used originally for the ground strap.

So the table top in cast iron tops is part of the circuit for the switch?!? I don’t think I really understand how the top has anything to do with the electric circuits of the saw. I would have thought a copper wire would be far safer and more predictable than using the fence rail … I don’t think that would get CSA or UL approval here…
