I was looking at the flat base mortars at "blackpowder-cannons.com". very reasonable price on the golf ball mortars and I think it would be a hoot with exploding shells/aerial bombs. My question is about the rod sticking out to the rear on the left trunnion, what is the purpose?
I've been making exploding shells for my homemade 16 gauge mortar using 5/8" OD cardboard tubes with a 20-30 grain ffg launching charge and have the fuse length pretty well worked out but would like a bigger aerial bang. The golf ball mortar could launch the 1 5/8" plastic ball shells for a good loud aerial blast.
Coyotejoe, I moved your post out of the classifieds and here to the discussion board. Please no discussion posts in the classifieds.

A bit of confession, the subject does interest me. I would like to learn more.
