Model Armstrong Cannon. Machining the trunnions-3.

On my “reject” barrel the silver soldering was problematic, and one trunnion was subsequently glued into place with Loctite 620.  This proved to be so effective, clean, and controllable that I used the Loctite for the main barrel.  The following video shows the Loctited trunnions being machined, and showing no signs of being dislodged.

It also shows a possibly dodgy but successful method of rounding the ends of the trunnions.

The finished trunnions and shoulders.  Resting on a 3D printed platform which is quite handy.
