Campag. Chainset Bodge to Triple
« on: February 01, 2015, 05:00:04 pm »
Here's my bodge to my Campag. Chorus double chainset which I converted to a triple to enable me to run a 28t inner.

Has been in use for 21 years now with the inner chainring being replaced twice.

The bolts used are 6mm high-tensile steel countersunk headed.

Spacers are made of drilled aluminium rod with the angles filed on to suit the spider.

Front mech used is a Chorus (circa 1992), controlled with a down tube friction lever.

Nice! I wouldn't fancy drilling a chainset myself, but if it's lasted 21 years then it must be ok!

Brilliant - just brilliant. How did you centre the ring and make sure the holes were in the right place?

Prior to my retirement I was a toolmaker at an engineering company.
I therefore had access to all the C.A.D. programs and also to the Computer Controlled machines in the workshop.
Very easy to centre the the holes in relation to the square in the crank.

Surely the use of Babbage-Controlled machinery takes it outside the realm of the True Bodge ;D

Yep that's actually engineering. Nice job!
