Looks great man.
Suggestions(sorry if you did talk about any of these)
-Round column vs square column
-Planning to convert to CNC or not(And you could even write up a TON of info on CNC converting alone. Or just cover the basics needed like drivers stepper motors or servo etc etc) Its needed for most anything cosmetic that aren't geometric shapes. CNC mills and Manuel mills both have their places. Your need to understand your goals before purchasing one or the other. Or converting at some point.
-Weight isn't the only thing that affects chatter. How its actually built does. Weight helps but if it has a poor structure then you'll run into accuracy issues not just chatter.
-A few new links. www.efunda.org
are also very good learning sites. Cnczone being forum based.
-Most machines that are sold by companies. especially your harbor freight enco grizzly machines. Everyone has the exact same model and may offer different options or prices but the actual mill or lathe is the same. Remember that!
-learn chip cutting formulas and find tables for feeds and speeds. I've seen a lot of people who make chips that seem "dusty" and I want to smash my head into a wall. That is not proper chip formation.
Well I think that's about it. Anyone who gets into this will have a lot of fun. For me its a hobby and a job!
Also. Mills inorder to be used as drilling must use center cutting end mills or drill bits! For manual mills DRO's are very handy or quick change collet system So you dont have to re-measure your distances when changing endmills or drillbits.
