As some of us know, there are only two sharpening machine options, if you want to use 3" grinding wheel. Incredible Edger and Blademaster BRPD1. One reason why I end up to IE is that I could not find any user experiences or videos from the Blademaster machine. Even today its extremely difficult to find information about Blademaster machine. To make new potential skate techs life easier, I added some Blademaster photos to here. I hope they help to understand how it works.
