I have been drilling. But its a long process with gradually going up in bit size until I can get a large enough extracting bit in there. Plus my lame battery drill is not powerfull enough. Thinking of getting another that plugs into electrical. May be my bits are too dull. I was going to go to test and tune for bikes at Loudon on Thursday from 1-5 but I don't want to go without a steering damper. Still waiting for clamps.
