Peugeot 103 long seat

I had been toying with the idea of using this long seat on the Peugeot for a while. I had originally used it on my Tomos when it was more of a daily rider bike. Anyway I offered it up and the front bolted straight on. I really like the look and once I sat on it that really made my mind up. It's so comfortable.

Peugeot rear mudguard + paint

I had this mudguard off an older 103 in the spares box and liked the look of it. I used a flap wheel to key the paint and remove any surface rust. Next I used some white primer. Once that's dry I'll paint it black to match the frame.

Reversed freewheel broken and fixed

After installing the new chains I peddled the Peugeot to check all the belts and pullies were working as they should. It didn't take long before the freewheel bent the bolt holding it in place and unscrewed itself.
I beefed up the bolts holding it in place so will see if it holds up.

Peugeot engine and radiator install

When I came to intall the engine on the new frame I found that the hole through the frame was 10mm but the hole through the engine was only an 8mm. I bought some M8 rod and 8mm id tube for spacers and it bolted on perfectly. Im still not sure of the angle that the engine needs to sit at so the carb clears the frame but for the photo I jammed the spring in there so the belt was tight. I also fitted the radiator and adjusted the stop on the front forks so it didnt hit it.

Reversed freewheel

Ok so for this dual variated project the free wheel needs to run in reverse as its on the other side of the bike to a standard single variated setup. Basically what this involves is installing the freewheel with its outer face (shown below) facing inwards. Unfortunately this means that the freewheel needs someway of being locked in place as when the bike is pedalled it automatically wants to unscrew it self from the hub.
 
 
So here's what I did. I drilled and tapped a hole in the side of the hub so I could install a thin screw headed bolt (shown below in red).
 
 
This meant that when I threaded on the freewheel face down. I could back the bolt out with the use of some pliers so that it would lock into one of the tabs (shown below).
 

 
It works the freewheel is now locked in place and ready to use.
