As a long time professional woodworker, some thoughts..
I consider the router to be the scariest tool in my shop, no question. I have a 5HP bandsaw, a 5HP Unisaw, a big spindle sander, a big, oscillating belt sander, a 25" widebelt sander, a 3HP router table, and a good number of other things that bite. The router can go from all fine to disaster more suddenly than any of than all the others, IMO, and in a more catastrophic way. Fingers can be sewn back on, mangled fingers can be repaired, often, but the router, when it bites, it will sometimes take a tendon and wrap it up, and pull it out from the body so that there is nothing left to repair, short of tendon grafts, if you have some to spare. The router will turn fingers into bloody overspray, bones too, nothing left to sew back on, or repair. I have had some close calls with some of the tools over the years, and only one real accident, with a pneumatic drill. One of my first experiences with a real shop router was routing a 1" x 1" piece of nice clear Maple, and having the router break it while I was holding it, in between the bit and where I was holding it. It felt like a baseball bat hitting my finger tips, impressive power. I do a lot of pattern routing. I never enjoy using the router, though I enjoy what it does. Always have huge respect for it. Little tiny 1/8" roundover bits, sure, not too much danger there. When it gets up past 1/2" straight, or flush cutters, there is a real danger factor there, if you recognize it or not. The router is indespensible, and all my tools, including the router, are top notch. My router is in a table with a Jessum lift. The router terrifies me. Do not underestimate it's ability to get you a helicopter ride faster than you knew possible. Still, people use them everyday without accident. Thought I would share this for those who are new to routers.
Personally, I am building a jig for a 108" oscillating belt sander, for beveling fins. It cuts very fast, and with a well designed jig, the bevels will be quite accurate.
I like the design of Jim's jig. If I were going that route, I would make on that had a stable platform, maybe a quick release hold down clamp to back up the double sided tape, and I would design the 'sled' so that it left very few options for my hands to be in harms way, and minimal sharp edges or corners.
