[Vwdiesel] Re: bob slater/boltophobia

[Justin and Chelly Bennett]

There are tools called thread chasers.  They look like a dulled tap.  
The reason is that a tap can ruin a set of threads if used as a chaser.  
If the tap is cut for a looser class of fit then the threads it will 
remove required thread material and thus leaving you a thread that will 
be out of spec and will be loose.  Not sure as it makes much difference 
with the vw, but it could.  So if I can't find the metric thread chasers 
I'll be using the homemade bolt option.
