Thanks guys. I'm thinking of making grinder attachments for sale. I can do custom designed parts for replacement or a new machine. I will be making my own wheels. I'm ordering a 2" think aluminum plate, so I can cut them any diameter. What would you like to see? For my machine, I will be building a custom cart with lockable casters so I can roll it outside on nice days. I will make several different attachments to go with it along with the ability to run longer belts if needed. Any suggestions for parts that are needed?
