Thanks for the link!

I didn't know these things had this problem or I would have replaced the lock cylinder as preventive maintenance! I'm unable to get the tumbler to move with various types of abuse. Looks like I'll have to do some grinding .

What I'd like to know now is what I should cut to get this thing apart. In the link the author drilled out the locking pin that holds the assembly to the column. I'm wondering if I cut off the cap, will I be able to get the tumbler out? I'd like to minimize the potential for damage and also keep from spending loads of $ on this lovely little project!
