Bring out the big guns

The portion of Battery Rodgers I will build a 8-inch Parrot in the front and a 15-inch Rodman in the rear. 

I am working on a diorama of Battery Rodgers in Alexandria in 1/32nd scale. This is a project I've been thinking about for a long time.  There are several photos of the Battery Rodgers and some plans  available. At least one of the guns survived and is now at Fort Foote, but on a different mount than what it had in Alexandria. 

I built the Verlinden 15-inch Rodman, a kit that has been in my stash for at least 10 years. It was a tricky kit with no locating pins and a rudimentary drawing for instructions. Some of the parts were broken as I purchased the kit used.  It took a bit of scratch building and lot of fitting and trial and error to get it to come out square.  It is impressive.



Next, I need the 8-inch Parrott on a front pintle carriage. No one makes a kit of this in 1/32 (Cottage Industries made the Swamp Angle Parrott but it has a different carriage) or 1/48 (for use onto Aquia Line). So I decided to draw it in Fusion and try printing them on my 3D printer.  It will fit on the printer in 1/32nd scale. I will probably print the barrel as a separate part, but the elevation screw will be tricky. I still need to add some details, but it's about 80 percent done. .
