Here's a better view of what Chuck was trying to do. That grinder was powerful, but there was a cost. It must weigh 20 lbs! Even the guys had trouble handling it at these angles. What we ended up doing was a combination of what you see here, and I went on top of the bumpa with a rope, which we attached to the grinder, and I belayed the grinder (supported it with the rope) while Charlie guided it. Chuck helped reach areas Charlie couldn't from the ladder. It ended up Chuck was right, in about 30 minutes we actually were done! Amazing!
