I was changing valve covers tonight on a 03 ranger 4.0 sohc and needed an 8mm deepwell socket to remove half the bolts because they have a stud in the center.
I didn't have one and I couldn't go to the store on thanksgiving so I improvised by grinding the chrome of the area to be welded on two BS brand sockets, butted them up in the cross slide vice and fused them together with the PP256.
Worked perfectly... it'll never see much torque so I'm not worried about it breaking. 3/32 blue tungsten, 50 amps set on the panel and gave it full pedal to start the puddle then backed off to about 40 to weld.
I know this isn't a "socket" weld
