Looking fore a line drawing of a Dictator Siege mortar. Side profile only, just want to make it look proportioned right. I’ve put my large cannon on hold tell the right design sparks my eye. Was at the local machine shop and spotted a nice piece of steel 16” long and 5.25” thick with a 2.75”hole bored in it. Turned out to be a drop from a job he just finished 4140 heat treated and normalized he said it would have a yield strength of 100,000 psi or more. Cost me a nice crisp 20 dollar bill. I even carried it out to the truck for him.
