went to a wing ding party at my nephews tonight. hence any grammar/ spelling / punctuation glitches excused. he dabbles in building gun powder model cannons w/ projectiles. from 1/48 scale to 1/2 scale to working near full sized replicas. he let one go tonight & it lit the yard & gave 1 loud report!! everybody was wtf??
anyway, their must be a science to that recreation simular to re-loading your own gun ammo. this guy's work is amazing!! he tools the brass, lines the wheels in metal etc. great work!! & meticulous!! these ain't potato guns, but that's another topic!!
