Here are a few photos of what I've been up to for the last few days. Photo below shows the original extractor from the .410 barrels on the left. On the right is the extractor which I've made for the rifle barrels. Once it is fitted to the barrels I will finish-contour the radii and cut the rim recess, using the chamber finishing reamer.

I also had to fabricate a forend hanger for the rifle barrels. Photo below shows it beside the original on the .410 barrels.

Another job still to be done is the machining of the combination top rib / quarter rib. Photo below shows a piece of cold-rolled steel, temporarily soldered to a square tube, which is clamped to a very rigid piece of aluminum I-Beam. This will be clamped in two milling vises for machining.

More to follow.
