Bomp, still learning myself


Was in the middle of media blasting the innards of the lift gate and noticed the threads for these nut plates didn't look too "full" A test with a 10-24 screw showed that some of the holes were so bad that they had a "slip" fit.





These hold the rubber bumpers on the bottom inside edge of the lift gate. The spot welds are drilled to release the nut plate..








The new ones are cut out of some 10ga steel, holes drilled and tapped.





yeah, these threads look much better....





Where I normally use a couple screws to hold nut plates in place for welding, with the close proximity of the plug weld hole the screw heads would obscure some of the hole, and we would undoubtedly be welding in the screw heads for difficult removal. For this case, we'll use some brass tubing as a spacer. Since the tubing I picked up passes though the screw holes, a sacrificial lock washer is used for it's minimal diameter.








A dab of anti sieze is placed on the screw threads to insure they don't get welded in place from arcing across the threads.. Plug welded, and screws removed.





Lock washers removed and plug welds ground flush....








And now we can finish up the media blasting....
