Fixed Gear Conversion w/ Vertical Dropouts & Rear Hub Spacing
So on ebay, I purchased a Masi Coltello Road Frame w/ an Alpha Q carbon fork for only $235. Such a good deal, couldn't turn it down. But now I realize that the thing is, I ride fixed and the frame has vertical dropouts. How would I make sure the chain tension is tight? Would I have to somehow find the right ratio and chain length to make sure the tension remains tight? And also, I didn't even think about it when I bought it, do you think the spacing for the rear hub would be too large to insert my rear wheel into the dropouts as my rear wheel is a single gear? The frameset arrives next Wednesday and I want to get some of my answers clarified before it arrives so I know what to do. Thanks!
I posted this in Bike Mechanics too, but wasn't sure if that was the right spot so I'm posting it here too
By the way, I can either run a 46x16 or 46x18

Chain tension would be an issue; but it can be solved in many different ways; for the most proper and most aesthetically appealing way, you can use a special white industries eno eccentric hub. But there are also cheaper ways, such as a half link (tedious), finding the magic gear ratio (lots of guess work), and a rear derailleur type tensioner (singlespeed only; the chain would otherwise jump if you ran fixed).

Repeating what was said here and in the mech's forum... the eccentric hub is the way to go.
