Weekend update.
While the aluminium repair worked, The heat from it has shown that the casting is suffering more cracks that couldn't be seen. When I came to fillet the lugs I used a water bath to stop the casting getting too hot on the already soldered side. Steam and bubbles appeared in a lot of locations, So either the metal is porous, or the casting has catastrophically failed.
So I took a different approach to the problem.
I removed both locking lugs and a good section of cast material. I then dry fitted the gun parts and took a few measurements.
With that information I went and looked at my pitiful home steel stock, I only had 40mm x 3mm angle section that was suitable, everything else was a little big.
So I split a 12" length of angle down the seam, Cut off some parts from the newly made 35 x3mm flat bar and got to work making a steel shoe.
The shoe isn't finished yet, I have to grind back the faces, Add in some filler sections, Grind out the rear side for the receiver covers, and drill 2 holes for the screw mounting. As a dry fit without any screws at all it's so solid you can pick the gun up, wave it about, hold it at either end in any orientation and it doesn't move. It takes 2 hands to split the gun and some considerable force as well!
Pictures will follow in an edit.
