Just keep wiping regularly with an oily rag. That’ll arrest the corrosion and avoid changing the finish.
Don’t ride in your best bib and tucker though.

Yes happened to me in the early 80s. I ordered a custom 5 speed Regina freewheel from my then LBS and happily went off on my first ever CTC 100 mile reliability ride. Halfway through I noticed I could not put much pressure on the pedals when using the 2 smallest sprockets. When I got home I found th...

That 8 speed was on a par shifting wise to Dura Ace 11 and so far ahead of Shimano at the time. Their reluctance to design more user friendly cassettes and chainsets has cost them hundreds of millions over the years IMHO. +1 My Campag 8 speed Veloce and Shimano 8 speed STX-RC bikes shift much more ...

AFAIK Campagnolo only go up to 26t on an 8 speed cassette.

I don't have the facilities to harden and temper tool steel. I'm assuming mild steel is harder wearing that al alloy chainwheels.
Do you have any better suggestions?

What it says in the title.
I'm going to try to order some of these, in 2.0 mm thick mild steel, from my local waterjet cutter next week.
He quoted me £10 each a while back.

PM me if you want to add to my order.

Back to the question in the op title; IME bushes need to be reamed to size for a play free fit and the bosses may be undersize, tapered or even both. This means you might need bushes with an undersize hole which you have to drill and then ream. I managed to get a cheap but ok adjustable reamer from ...

I am still using a 97 Veloce rear hub. The O ring has become oversize but is still in one piece. I have not replaced the springs as they were not bent. I did have to replace both internal sealed bearings in the freehub and both axle cones (and balls of course). Re lubrication I'm currently using a C...

Drill hole first? Eat pudding before that ?

I managed to get a price from my local water jet cutter. Looks like custom sprockets will be about £10 each; going down to about £7 for larger quantities. Standard material thickness is 2.0 mm.

I will probably end up getting two of each (28 and 32 teeth). Does any one else want any?

I will investigate if splines could be laser or water jet cut economically. I have drawn up a 28T and 32T sprocket with an inner hole to fit a Campagnolo 8 speed (8 spline) freehub. My local waterjet cutter did not laugh me out of court, so I intend to send them CAD files to get a quote and some id...

Mick F wrote:I think I'm correct in saying that there are some cassettes with the big cogs are alu.

Yes indeed. Probably the ones where the bigger sprockets are riveted onto a carrier thereby not contacting the freehub directly.

Sounds like a lot of faff to me! IMO, a lot easier to just replace the front chainset with a lower-geared one, so to use the current stock of cassettes with 28t sprocket? One man's faff is another man's hobby in retirement :P . It keeps me off the streets :lol: :lol: :lol: Besides, I like my Shiman...

Does it have to be steel? Many chainwheels have less than 30t and they are alu. Difficult bit would be the splines of course, but maybe they could be bolted or riveted to the adjacent sprockets. Don't forget that chainwheels are bolted on with big fixings. The dog-spline(?) contact on a freehub is ...
