I used a punch and hammer to take the spacer out of my seven speed freewheel, and then cut a piece of PVC pipe to make up for the rest of the space. I used a 14t shimano dx freewheel ($4, only project related expense) and I used the middle gear which is unfortunately permanently joined to the granny gear up front which is a 32t....with a homemade halflink (not recommended unless you have done it 100 times) I have a perfect chainline.....with a tiny bit of slack.....I am going to go out and get a 31 and a 30t sprocket to see if I can get a perfect chainline without a halflink one of these days, but for now, its fun, and noticably lighter than before considering the cheap shimano acera components I have been nursing along for the past 6 years!!!

I also had to hack apart my brake levers as they have integrated shifters, they're not the prettiest thing ever but it works....pictures to come when I get the sprocket and chainline thing sorted out!!!
