I recently picked up this Electric which has interesting scales as well as a neat leather pouch for storage.
The one scale was missing a small loop which I was aware of but figured I could repair it.
I took another old Bakelite scale and ground it to the shape of the missing part. Once I had the 1/16th loop made I addressed how to fasten it to the scale. I didn't want butt joints so instead I opted for half lap joints knowing they would be a bit stronger as this piece is vulnerable.
I made a pocket on the left hand side of the loop ( hinge side) and flattened a landing area for the right side of the loop.
As luck would have it when I was breaking down the blade to remove the scales the bit slipped while drilling the pins and I created another hole right next to the pivot hole in the scale. Great! Another repair. So I made up a small 1/16th inch 'rod' out of my old junk scale and flattened one side of it. I epoxied this into the new hole I created with the flat facing the original hole. I did this to lessen the chance of the bit drifting when redrilling the hole for the pin.
I cut off my plug, sanded it flush then polished it. Since this set of scales is rather delicate I couldn' t use the buffer on them so all the nooks and crannies were polished by hand. I also did a clean up of the blade but didn't take it to full polish.
Now it's complete and solid.
Here you can see the sequence of the repair up to the point of the loop being epoxied in place but not sanded or polished.
