So did you use hand tools? Hack Saw, file etc? Or did you use a dremel etc?
I have a dremel, but I don’t know whether to bother buying the cutting discs, and grinding or just go at it with my hand tools.

Your advice and any pictures blogs etc much appreciated.

Thanks

Tom

Big saw and a big file.Followed by a dremel and small file.Followed by endless wet and dry.Finished with autosol and a buffing mop.
Not to be undertaken if you suffer from ocd…..it never ends!

I’ve got a few sets of cranks, going to ‘Jones’ one of them soon I think! The other I may sell 😉

Buy up 102bcd chainrings now…..while they are cheap(ish).

done a couple of sets of deores,a la Jeff stylie….

angle grinder,bench grinder,files,wet and dry, bench polishing mop.

takes about 6 hours start to finish,inc. removing anodising with caustic soda.

oh,and drill a couple of holes to make em look xtrish !

33t rings are £26 on crc now.

What’s a Jones conversion?

Cut mine with an angle grinder then filed with a bench grinder. Took about an hour including strip and rebuild. Didn’t bother with the caustic soda and endless polishing however.

Ive got the ring, I’m just want to have a clear plan, before I cut an F them up.
Mandog- what ring is that you are running.
Tollah- how much for them if they are M960s? I always have uses for a second, third and even fourth pairs..

propper.

tommid – it’s a 32t ordered from the USA but I can’t remember who.

xckeith – nice, seems a shame to use it

Looks like a homebrewed components cog to me.

mandog,not mine,those are the real thing,mine are much nicer 😉

Here you go:
cut off the outer part of the spider with a piercing saw

file off the top surface of the spider arms with a course file

round off the ends with a course file, emery and polish

middleburn chainring

Tommid not too sure really as the pair I’d let go have had protective tape on since new and are In pretty good nick.

Forgive my ignorance, what’s the point and benefit exactly? What does it offer over a normal crank?

I have a “jonesed” drive side spare – some wear on the splines, life left in em I rekon though.

niche innit.

It has the benefit of BEAUTY.
