Nothing is more ON Topic than keeping vintage lightweight bikes on the road!

I inadvertently deleted an email from a fellow lister last night enquiring about
the reproduction bolts for a Chater Lea chainset which I have just had made by
my neighbour Derek. I know that some may think this OFF-TOPIC, but there are
times when certain parts in proprietorial dimensions are becoming very hard to
find - therefore, when needs must ...
So here's the update - last week I gave Derek three bolts kindly supplied by
Derek Athey as templates. He took them to work - he is a tool-maker at the
National Research Council here in Ottawa and does exquisite stuff. Anyway, a day
later he presented me with two sets of bolts in stainless steel which are
absolutely fabulous. He did have to retap the chainset slightly as the threads
had been damaged at some point - maybe during rechroming. He managed to
reproduce the 17/32" X 25 pitch thread as close as possible. It took him a while
to set up and he reckons that although the materials are relatively inexpensive
it would not be a very cost effective venture. On the other hand, once set up it
was easy to mill more than one set at a time. Needless to say, I am thrilled -
they won't rust!!!
This evening I took over a rear centre brake bolt which came from a Bowden
Touriste, but is set up for a French bike of the 30s-40s (with the clip which
goes over the brake bridge and a vertical fastening hole). He is going to make
me a replacement bolt with a standard spindle for a British set-up. He thinks
that it will actually be easier than the chainring bolts - surprised me! He then
showed me the lathe he has in his basement and said that he could actually do it
there, but will probably take it into work. It is great to have a mate who takes
such delight in having a go at new things! I am going to owe him lots of
landscaping help and advice in months to come.
