CR#5

My numbering scheme is based on the chronological date of
when I started a project not when I finished it. Number 5 was finished a year before
number 4. I hesitated finishing CR#4 because of the weight of the bike and also because I
discovered hairline cracks in the weld joints.
CR#5 was started as a quick bent project, it started life as a type of bike that was known
as a Formula One. I simply brazed a 1 1/2" square tube to the front of the head tube
and tried to braze a homemade BB shell to the end of it. I say tried because it broke off,
I repaired it with a plate of aluminium, some bolts and rivets. The seat was plexiglass
and camping foam. The seat back support was a 1" tube that was placed inside the seat
tube and extended 18" above the frame. The stem was made by hand mitering tubes
together to form a stem that had a rise of 18" and an extension of around 8". I
later shortened it down and put it on CR#4 when I repainted it.
CR#5 was rideable but not much for performance. The frame flexed even when just riding on
level ground. It had 6 gears, 2 idler wheels on the non drive chain section. This bike's
frame is the most recycled of all the frames I have used. The original BB was later cut
out for CR#7 and the rear triangle ended up on CR#12.
