Bicycles in old age of Japan (website)

I have no idea where I got a bookmark for this website, as I don’t remember coming across it. Combined with the fact that the Japanese fonts aren’t coming through and even if they did I don’t read Japanese, I can convincingly say I know nothing about this site, but it sure has some cool stuff:

Like this “Eddy Merckx” mixte Randonneur as well as plenty of other French style bikes

and lots of bizzaro bikes and parts:


Fork Bender- first results

I went over to see the guys at Circle A as Brian had finished fabricating the fork bender and I wanted to see the test results. Brian had made some changes as he had an old part that he could modify to act as the fork tip restraint:

Overall, I’d say the results are excellent for the first bend, though the blade wasn’t bent all the way to the tip.

Since the restraint needed to be mounted to the table, Brian raised the block up off the table a little so he wasn’t grabbing the very tip of the blade. Additionally, he forgot to install the bracket that holds the end of the mandrel in place. Combined with the fact that the restraint is no longer tied to the block directly, this allowed the block to move a little relative to the restraint. As a result, you can see that while the blade is beautifully bent, with no rippling or bending in the upper portion of the blade, the tip of the blade is not bent as it raised a bit off the block.

Installing a base so that the block isn’t flying in the air and installing an angle iron at the end should fix things, but if there is still movement, he can install a strap that ties the block directly to the restraint, somewhat like the original drawing, but perhaps a bit lighter since he has the restraint bolted to the table and all he needs to do is prevent them from separating.

Here is the blade:

and another shot of the complete bender:

I suggested a couple of slight mods to fine tune the power of the arm, but Brian says he can easily bend the blade with one hand.


LED Replacement Bulbs: SCORE!!!

A friend’s mom lives in Germany and was good enough to purchase these for me. The taillight with standlight works great and is much brighter than the standard bulb that came with my old Radios taillight. The replacement front lights (no standlight) are the wrong base type, however, for my Lumotec:

The headlight replacement bulb has the same size base as the Lumotec bulb, but it is the type with two bumps on the base. The Lumotec bulb has a slightly wider shoulder, with a small notch in it. I ground off the bumps on the LED replacement and now it fits and works great. It seems to be much brighter than the halogen bulb, though it may lose a little of the focus. It is not nearly as bright or well focused as my Edelux however.

It is the taillight that I am stoked about, though. My initial impression is that this is brighter than an old school taillight, but not as bright as some of the newer Busch and Muller taillights out there. The standlight lasts as long as on my factory LED taillights. I will try and post some comparison shots.
