While expensive, the Bow fence extender and its accessories are worth it. I built a workbench around my Hercules table saw a couple of years ago. While it has a 3 ft outfeed section, its infeed section was lacking. Watched a few YouTubers demonstrate how to build a larger infeed section along with extending the fence. I was going to build something until one day about a month ago I stumbled on one of the professional woodworkers on YouTube promoting the Bow fence extender. I was sold and bought the 46” along with all the accessories. Have been using it to build 2 barn doors. The 46” is the way to go. Gives me about an extra 20-22 inches of infeed. All pieces are of high quality and well made. Haven’t had the need to double stack the feather board duo pro yet though. Anyway this fence extender has allowed me to make some cuts that I couldn’t before and also ensures more accurate cuts. Overall I highly recommend this product. Sure some people can perhaps build something that may work but i guarantee it won’t be as good as the Bow extender. System appears to be expandable and so I’ll be curious as to what other accessories could be added down the road. Thanks Bow Products for a great system!
