i have this mountain bike sitting in the back of my house, we've had it for awhile now and i'm thinking about taking it out because gas prices is cutting into my lunch budget. The brand of the bike is univega, if i was to turn it into a single speed how much money will i be looking at? This is my first bike project of any sort and i heard it was possible if done right, so any tips would be extremely helpful. Thanks in advance

my motto throughout this project is if it's works its good, so my budget on this bike is limitless but i dont want it to cost as much as buying a car by the time i'm done with it
