Sear plunger pin and S-link pin removal

[4 Scale]

I used a slightly larger drill bit, also mounted upside down, to press the pin back in. I also built a crude wooden jig to keep the plunger in its channel at the correct distance as I pushed the pin in. I was concerned the spring might pop out during the reassemble. I was not optimistic that anyone would have a replacement spring in stock.

The jig worked and the press of the pin was smooth. It is a tight fit and flush.
