I've developed a way to TIG weld poorly placed scope mounting holes that is (I think) perhaps a little different and offers the 'casual' welder a way to accomplish it without too much stress. First off I have to say that the word TIG is the a magical thing that we all read about on the web. After MIG and stick welding, only oxy-fuel imparts more heat into the effort than TIG, especially when talking about short welds.
Here is a 96 Swedish mauser that was seriously funkified.

The receiver holes were at an angle and the aft one bumped the locking lug boss along with being rotated off center and pointing towards Bethlehem. The aft ones were scattershot. More or less a junk action. I have several. Filling a hole with weld to make sure there is enough material to re-drill for threads to take can be a problem. If the holes are close to being on center then the weld needs to pretty much fill the void. That is what creates a problem. In order to do so, one needs to expand it it order to fill it. I could go on about this but what I offer is a way to avoid that so I'll hope over that. Amusingly, the duplex nails showing the angled drilling is the (my) solution to the problem.
More to come as it seems I have figure out how to dump pics to add more...
