Welcome Silver Fox. You can build a chair accessable router table. This being said I have never seen one but have some great ideas I will draw up and post. We will ask for input from other members, this almost always generates good ideas. Here is the starting information we need from you: How wide is your chair?(Outside dimension including wheels) Width of the arms?(outside dimension) What is the height? (Measure from the ground to the top of the arms.) What is the relationship of your legs to the chairs arm height?(Higher or lower? This varies by manufacturer and user) What is your measurement from chest to wrist with arms extended forward? Height of arms extended forward above the chair arms? And finally what is the measurement from your chest to the furthest part forward, chair or feet? Do you own a router yet? I am excited about this project, something long overdue.
