Why won't the back of my bridge take solder?

[PhiloB]

Trying to ground the electronics to the back of the bridge but solder won't 'stick'.  Using a 20W iron.  Do I need something more significant or is there another issue?

Its the chrome plating. Use a bit of sand paper and scuff up the place you want to soldier to. Also use flux to clean the area. I had this issue also.

PEC potentiometer covers are also known for not taking solder, in amp builds.

A dremel with a sanding wheel makes quick work of getting down to bare metal. Selfdestroyer is spot on. Flux helps a lot too.

Thanks guys- sanding wheel and flux.

All the above plus 20watts just may just not be enough spunk...

Never soldered to the back of a bridge, just smooshed the wire between the bridge and the body.

Drastic measures.

Jimilee, I got lazy and did just that.  Originally I had done that and experienced grounding issues.  So, I exposed more wire.  Working fine now.  Now I know what to do with a pot that won't talk solder though, I've run across that before
