Well, I looked for this modification and couldn't find it anywhere so I thought I would share it here. I ground off the lower tong angle making sure that I kept the length as long as possible. I didn't just cut off the whole angled end.

I did all this work with both trunions installed but the trigger guard was not installed. I don't know if the trigger guard would have made a difference but it appears that the lower tong modification would have cleared.

Once I got it to look like the flattened lower tong, this is where I did something different than what I could find. I purchased .25 copper welding tips that are threaded. I drilled the lower tong and then tapped the lower tong to accept the copper tip. Once I screwed the tip in all the way, I then got a dremel cutting wheel and trimmed the welding tip so it could fit into the receiver. The lower tong with the tip fit easily into the receiver.

I went ahead and ground the upper tong tip to match the diameter of the welding tip and spot welded the rails into place.

I didn't think it could be that easy.

thanks,
Ron

Here you go ... at least one version

I think the only problem with the otherdesign is that the lower contact point is still to tall to fit into a receiver with the front and rear trunions already installed? The way that I modified the lower tongs, I was able to spot weld with the trunionns and center support installed.

Here are what the contact tips look like...

I just got my spot welder today I cut and milled a flat spot in my lower tang, and went looking for a shorter copper tip. nobody local had anything, but they did have tons of those tips! I'll be goin' in the morning to get some. thanks for your convenient post

Nice idea!

I just cut off the bend and drilled & tapped the rod for a brass screw.   Then I shaped the brass scree into a point.  Works great.
