timing belt tools

[Link Brian <link@casa.Colorado.EDU>]

Does anyone in the Denver/Boulder CO. area have the special Audi tool to 
chaulk the pully wheel for my 2.2 5cyl. Audi number ???.  If so are you 
lending it out.  
Or could you describe it so i can make one myself.  (I am lucky enough to 
have free access to a full fleged machine shop).  If not,  Would anyone 
give the "should or should nots" on using a flat blade screwdriver to do 
the job.

thanks

well known tip of the day...change your fuel filter every 30000 miles or 
you'll be sorry.  BTW you can get a BOSCH at NAPA for only $17.
