Purchased a Rotozip this morning. The two in stock $59 version both appeared to have been opened and returned so I went with the $99 version and some extra cutting discs. Got home to find out that the Rotozip doesn't incliude a mandrel for the cutting discs. Broke out my trusty Dremel and cut the two sides of the canopy to the tooling marks. I put masking tape on the rollbar and marked the center line for the cut. I stopped because I need to research whether or not to rivet the canop frame and brace first. Plans don't seem to indicate so, but perhaps it is just common sense.
