Small Steps. Armstrong Cannon.
6 hours in the workshop today. I am constantly surprised at how little progress appears per session. Also surprised at how quickly the time passes.
I had left the external dimensions of the cannon chassis girders rectangular, to facilitate holding the items, while doing as many machining processes as possible with the rectangular shape. But today I bit the bullet, and made the final girder shape.
The 4 girders are all looking good. Next to start making end pieces and brackets. I am still waiting for rivets to arrive, so the assembly will be bolted together initially.
