Hello Don - Being for commercial use you are better off buying a commercial kit or a machine. Designing and building your own is a long journey and it will take time and effort to get things right. You want a job done and you need to buy the tool to get it done. I design and sell kit routers and its months of work to design one, test one then sell them. For someone who has not been through this it could be a year or more to sort. Read some of the build threads. So find a machine that gets your job done and buy it. Peter
