Re: 1960s Sun Snipe Prestige - restoration help!
So the bike is as far as I know 99% original except for the tires (and the extremely brutalist and corroded kick stand, which is now removed and in a box in the shed).
Planning to keep it as original as possible, then figure out what the definition of 'possible' is once it's more properly rideable. I am a bit sceptical about the steel rims, but this won't get ridden in the pouring rain (at least not on purpose), and also a bit sceptical about the plastic simplex derailleur. But the wheels seem pretty essentially OK, and the derailleur does shift.
If I do end up replacing the derailleur, how strict are people with authenticity - i.e. is any '60s or '70s claw derailleur OK?
Have some SCHWALBE Classics HS 159 coming in the post, and also some fibrax raincheaters for the steel rims (about 1/4 the price of koolstop salmons).
The cotter pins are very rusted, and the BB is surprisingly smooth as far as I can tell and potentially can be tightened from the non-drive side (at least it look possible). So thinking I'm better off leaving the pins where they are until there's a genuine problem to fix - on the basis that if I strip them down the cranks might not go back together again anyway so why do that before replacing the crankset? But opinions welcome. Also if I do end up replacing the crankset is it sacrilege to switch to (vintage) square taper?
So for now planning to clean up as much as possible in place - soaked most of the accessible bolts, and wrapped a few bits in white vinegar-soaked kitchen towel.
Don't have spare brake and gear cables handy, so waiting on those to clean up the derailleur and brakes properly.
First question - the surface rust comes off easily enough with white vinegar and some steel wool, but there's quite a lot of pitting. What do you lot do about the pitting? I can keep chucking GT85 at it and maybe some acrylic/lacquer but are there other options?
The frame itself is in good nick, with a few scratches and rust areas all less then 5mm across - is there anything to do apart from try to carefully remove the rust without making the spots bigger and oil it up?
Built in before/after with the pedals each side, since I did one at a time while looking at other stuff... Excuse the crap photo, weather was ropey and you can see why I borrowed the ones from the listing.
