I'm using the Porter Cable dovetail jig to cut rabbeted half blind dovetail joints for inset drawers. Has anyone ever had a problem with the tails not fitting? My first piece I had a slight gap so I lowered the bit but both times the tails would be "frayed" once fully connected. I've used the jig before and never had a problem. It's still fairly new and I'm using the bit that came with the kit.
Any thoughts? Is the bit already worn out? I've tried to make a few adjustments but nothing has worked yet.
