I have constructed an add-on to my BT3000 rip fence to hold two featherboards. I will eventually get around to making my own feather boards, making this is truly a hand made jig. For now, I will use the plastic feather boards from Bench Dog (www.benchdog.com).
I used toilet T bolts and then epoxy to secure a washer then had to do a little grinding on the bench grinder to get a good fit for the slot on top of the rip fence. I got the aluminum T slot from WoodPeckers (www.woodpeck.com). Original PDF Document:
