You will receive just the assembled upper to attach to your already existing 6-14 inch wheels. This will be a larger form frame. We will let you figure out that fun part : ) a cheaper option if you already have a wheel but would like to implement the automated upper portion of the Gem Bot. The it will include extra 2020 rails to help attach to your lower and all components such as touch screen controller, micro computer and power supply to make the upper mast function just as it would on one of our 6 inch laps. We have had lots of interest from potential customers that would like to use larger laps or that already have a manual faceting machine but would like the automated side of things and this is the solution! Please allow for a 2-3 month build time on all products as we create an inventory of machines! The more orders the faster the build time as we will have more funding for creating an inventory of parts! Thanks for your interest in the Gem Bot project and we hope to get an automated machine in your shop!
