I will start with the patch box spring wall of shame, there was at least 3 more failures not in the picture.The one that is intact actually worked.
A test fit showed it to be a little tall so I will have to inlet a deeper spot for it in the box.
First test run, putting everything together.
It works!
Just a little more adjustment to get the box lid down tight and WE ARE DONE!
Next, sanding staining and finishing the wood, and greying the barrel and metal parts.
