The Flandria Fixed Gear (Fixie) Conversion - Assembly

Assembly was much easier for this bike than in the past because I remembered to take a lot of pictures. And I kept each grouping of parts in their own bags so I don't get the small parts mixed up.

These older bikes have some great chrome and were easily cleaned. I used the Oxalic Acid (wood bleach in the hardware store) bath as I described in the Huffy Build.
The headset was pretty easy to install as long as you have everything in the right order. I'm liking the look of the raw steel, it gives the bike a nice vintage look.

My next goal was to cut the handlebars. I wanted to have a stripped down look to the bike. Plus there is no need to use the drop bars on a single speed. I'm using this bike strictly for cruising around downtown. I used a simple hacksaw and a vice. It gave me a pretty good cut and went through easily. I'm going to tape the ends so it doesn't need to be perfect.
This bike has a fixed cup bottom bracket. First, start with putting a healthy portion of grease in each cup and pressing in all the bearings. They should stick in there pretty firmly. Next make sure that you insert the spindle the correct way. See the picture below. There is one sire that is a bit longer than the other. This must go toward the crank side. Next, screw the cups on with a big adjustable wrench. That will not get it tight enough. And if you try you may ruin the wrench flats. The next part can be a pain unless you have some specific tools. There are three ways I know:
1. Buy the right tool from a shop.
2. Use a good vice and make sure the wrench flats are tightly secured. You need to keep the bike level or you will strip the flats. Do not over tighten, check to make sure the spindle turns freely but does not rock side to side. (My method)
3. You can make a Fixed Cup tool, described on Sheldon Brown's site.

The next tricky part is the cotter pin cranks. Refer to the original post for removal tips. To install push through and make sure to line up the flat side of the spindle with the flat side of the pin. Once in place give a nice firm tap with a hammer to set or use a press. Then screw on the cotter pin nut until tight. If the threads were damaged during removal you may be able to cut off the damaged part with a hacksaw and still have enough threads. The nut is not supposed to hold the crank on, the friction fit does that. It is just a safety measure so you your crank doesn't fall off. I also suggest after your first ride that you try to tight the cotter pin nut again.
 Next, I will be finishing the drive train. I asked for a 19 tooth fixed cog and chain for X Mas.
