1980 Feather Professional BMX Part 2

I’ve got the majority of the parts laid out with a few decisions to make along the way.

1980 Fuji Feather BMX Parts

One of the very distinct parts on the Fuji Feather Professional BMX bikes is the Tange Meriter headset. These are semi-sealed and were a very high-end part in the mid and late 1970’s.

When acquiring a Tange Meriter headset one of the most often damaged parts is the top-nut. I must have 10 headsets and probably 5 good top-nuts, 2 bad top-nuts, and 1 unusable. If you ever find these top-nuts at a swap, buy them!

Another very distinct part to the Feather Professional BMX is the curved Ishiwata fork.

Bar Keepers Friend really works!

I had heard about oxalic acid and its power to remove rust from bicycle as well as many metal parts. In my research I also found out the active ingredient in Bar Keepers Friend is oxalic acid. It just so happens that I had just received a rather rusty Fuji Feather Professional Ishiwata BMX fork and have a bottle of Bar Keepers Friend under the kitchen sink.

So, here’s what I did. I got a large plastic bin I had purchased at Costco some time ago. I put one cup of Bar Keepers Friend in the bin and then filled it with hot water until the fork was completely covered. I carried the bin outside to let it sit for a few hours. Before walking away, I couldn’t help but pull the fork out to see if any thing was happening. Sure enough, with the wipe of my finger rust was already coming off! I was looking forward to the result!

3 hours later I began to lightly scrub away the rust with a Scotch Brite blue non-scratch sponge. Below are the results.

One of the most distinguishing features of the Fuji Feather Professional is the Ishiwata fork. They are so unique there is no mistaking the fork if you happen to discover one. However, most the forks I have been able to acquire are too worn at the dropouts and the “Ishiwata” text engraving is gone.

It seems many people replaced the original forks with something after-market. I’m not sure if this is due to breakage or the unusual geometry. Both the frame and fork tubing of the Fuji Feather Professional were stamped and manufactured by Ishiwata Seisakusho Co. LTD. in Japan.
