Got home early and got a little time in the shop; had to do some trimming here and there, but they are mounted and ready for testing.
I couldn't bring myself to pay the extra $25 for the additional weight rings, especially not knowing if they would fit inside my wheels or not. After mocking them up the first time, I saw that there was room, and I needed just a bit more weight to match what I was running before. I dug through some washers and found some that were just right. After drilling and countersinking some holes in them, they mounted up perfectly.
The weights and washers:
Weight of the washer:
Mounted to the ring:
The bead-locking rings on my Motoworx wheels were a little wide to clear the weights, so I had to enlarge them a bit. I used an oscillating spindle sander, but a Dremel with a sanding drum would work also. They aren't perfectly round now, but they are functional. Pretty doesn't win comps, so I'm okay with how they look (since they're on the inside :mrgreen

. The ring on the left is the un-altered ring, the one on the right is what I ended up with after enlarging the inside:
The rings would have cleared the weights at this point except for the grub screw that holds the weight on the knuckle pushes the weight back just enough that it rubbed. Since I had already enlarged the rings as much as I could, I had to remove a bit of material from the back side of the weights. You can see where 2 of the screws (on the right sides) have flats where I sanded the weights down on my disc sander:
I also used a countersink bit to enlarge the center hole in the weights just about 1/8" deep to allow the hub of the wheel to fit over the hex better. Here is the final weight after clearancing the back of the weight and countersinking the center:
And finally, the weights installed on the rig:
Everything appears to clear nicely now, and is ready for testing. I'll hit some rocks tomorrow and see how it does and report back. "thumbsup"
