Collimating without a tool

Many of you don't know me, but I bought a scope because I had 70x15 bino's that I loved using; I spent 15+ nights learning the scope and eyepieces and practicing focusing with barlows etc (this was all before christmas as I've now had a kid who needs alot of attention - I'm now planning to get a night a week or so set aside just to use the scope).

I have a 8" GSO Dob from andrews and a couple eyepieces etc.
But I read quite alot about the mirror in the GSO dobs being held too tight - so I'm thinking of losening the screws that hold the mirror and making sure they not too tight - but will I wreck the Collimation on the scope? I've read a couple things about Collimating without a tool - just looking into the eye piece and seeing your reflection to test - But is this accurate? should I buy a Collimating tool before I loosen screws?

Sorry for the mass block of text post I hope someone replys
