Hi Jim.
Can you post any close up pic please so we can have a good look.
Regards Bill.

Hi Colin thanks for the reply l dont think they are either brass or copper l have given them a good filing they are not coated.
Has mentioned l will have to cut them down to fit so l will definitly find weather they are coated in anything.
keep safe. Jim.

Hi Jim, are they brass, if yes it should be easy. Some shaft supports are plated tin or steel, which is solderable once cleaned thoroughly. I use bakers soldering fluid to help the solder flow on steel.
Or silver solder should work on any of these.
Any pictures that could help identify.
Cheers Colin.

the metal can be soldered.
Didnt mean to put up two posts my thumb hit the post reply on my laptop. hey ho!.
cheers all please stay safe. Jim.
