Here is a link to the Shape & Sand I was referring to earlier. It can make all of the parts on your website products page and several other shapes you don't show. It sands both straight and arched panels. It also sands outside profiles.
If you visit our site you can also check out or other machinery by holding the mouse pointer over the "Machines" link on the upper left. The Single Spindle Shaper and Dual Spindle Shaper may also be of interest to you.
Our contact info is listed on the site, feel free to call me with any questions.
