some details about the mortar that I am building.
3 inch outside diameter barrel, 1.75 inch bore, 7 inches long, .625 inch wall
powder chamber is 1 inch diameter x 1.75 inch deep
total wall around powder chamber is 1 inch thick
all but ready to place the powder chamber into the barrel by shrink fittiing.
I believe I will heat the barrel to do this.
Tried to include a rough drawing but for some reason it did not show up.
welcome all questions or concerns
