Hello, All... I am in the process of installing a Raytheon ST5000+ (below deck) autopilot on our 2000 Catalina 36. So far, so good with the electronics part. However, per Raytheon's suggestion, I have decided to install an auxiliary bronze tiller arm on the rudderstock, rather then attaching the hydraulic ram to the cable wheel. I ordered and received the tiller arm from Edson.Installing the arm necessitates drilling a hole (about 5/16" or so) all the way thru the rudderstock, so that the tiller arm unit is thru-bolted (as well as using the 4 peripheral bolts.) I am pretty handy, but the rudderstock is a substantial hunk of steel and the job seems just a wee bit intimidating.Besides the advice of "have a yard do it...” does anyone have any suggestions about the best way to approach this task...and the proper tools to use, including drill bits, jigs, etc? There is a collar on the tiller arm that appears to be able to serve in keeping the bit properly aligned, but that may not be the best approach. I am a good wood-worker, but have limited experience with "heavy metal."Any advice would be much appreciated. Thanks.Bob GauvreauC-36, "Purrrfect", #1929San Francisco, CA
