Re: [ATM] Two questions on collimation bolts

[ntent <ntent@pctcnet.net>]

Ace indeed does have the inserts; or at least all the ones I've been 
to.  They have a section in their stores with lots of small drawers 
containing all kinds of small hardware, like set screws and such. The 
ones I've seen and used are brass inserts.  Just ask the "helpfull 
hardware man."   8^)
