Bought an old built Nu-Cast B1 recently, very nicely made but a bit mouldy in places. Had never been run so had a go at cleaning up chassis - white metal, solid as the proverbial brick outhouse.
It has what look like old Romford wheels with rods held in place by solder. Had to remove a couple of rods but when tried to put them back found the crankpins to be of a solder repellent metal. Anyone know what the metal is or more importantly how to get solder to stick to it ? Have filed pins so theyre clean and once in a rare while they do stick buut its very rare.
Any help appreciated.
Cheers, Simon
