Trouble drilling/tapping primary fuel plugs
« on: July 19, 2014, 06:44:22 PM »
I bought Cliff's fuel plug reseal kit as it sounded easy but I'm having problems. I drilled in about 1/4" on both of them and can't seem to go any deeper, it looks like the heads of the plugs may have broken off. I did try some smaller diameter drill bits but it didn't do any good. Right now I can barely even tap any threads in there either to hold the set screws , using 10-32 tap and #29? bit that came with it. Does anybody have Any suggestions on what I can do to get the remainder of the plug out so I can seal them off ? Will a small torch work? I don't want to damage the crab so I'm trying to be careful.
Thank You

Never mind it ended up having steel plugs in it and the regular drill bits couldn't cut into them.
