I've been struggling with how to get a good glue fillet at the temporary wire locations between the hull sides and bulkheads. You can come back once the glue is almost cured and remove the glop of glue that inevitably sits behind the wire. Trying to do a finish fillet over such irregularities is not easy if you want a smooth finish. Sanding isn't the best option for removing a large amount of resin nor is a chisel. Luckily, there is a great tool and hardware store where I live, Hardwicks. They have everything. I searched there shelves and came up with the pictured die grinder bit. As I own a die grinder, This looked like the perfect tool to smooth out rough spots. It did the trick. I was able to grind out the worst spots in preparation of doing the bulkhead fillets in about 20 minutes. The photos are a before-during-after sequence.
