Review on BOSCH RA1151 Centering Pin and Cone Router Subbase by Charles Alvey

The fit and finish of this accessory is not what I would expect from a Bosch product. Inserting the pin into the cone wasn't as easy as some reviewers might suggest. I tried to insert the pen manually and it didn't work. The bundle of plastic ribs needs to be deformed to fit/center around the pin. Do not use a metal hammer to drive the pin into the cone. I made that mistake. The pen is soft and swells when struck with a hammer. I had to cut the chain to fit the pin in the 1/4" collet. The method I ended up using was to place a 2x4 cone with a 5/8" pin hole and place the pin with a plastic mallet. After all the trouble assembling the centering cone, I have no confidence that it will provide appreciable positioning accuracy. Oh, someone mentioned that by flipping the pin, you can use this centering cone on a router that comes with a 1/2" collet. Well, good luck to anyone trying to remove and reinsert the pin. Will a plastic cone withstand that much cruelty?
