I’m having trouble soldering the ground wire to the trem claw. I’d heard you need a strong enough iron and I’m using a 40 watt Weller. Before I got this I was using a Wal*Mart nontemperature controlled 110V iron. Thought that was my problem but since I got the Weller I flow a nice bead and it cools then releases. Using flux (Rubyfluid- local product) just makes it worse. I’m wondering if I should drill a small hole and put the wire through it then flow solder.
