Thanks for the replies. Don, if you can point me towards that 4 inch shaft, I would appreciate it. It may be right in front of me somewhere, but I sure have not been able to find it.
I did look at the flex shaft a few days ago. I almost bought it, but I think that in the end it will still be not quite the right solution. I'm still debating that one however. Maybe it is narrow enough that it actually will do the job. I may have to reconsider.
Signature? I dont need no stinking signature...
