Single shot 3" Mortar Rack. Dimensions?

[xjaayy]

I've made many 8/10 & even 20 shot 3" racks. But How do you all make your single shot 3" rack?

Something that works safe. What are the dimensions?

Lol.... who uses a "20" shot 3" rack? Actually... how do you carry it? To answer your question though there is no such thing as a single shot 3" rack since this is now display fireworks. I've seen a 3" steel tube buried in a barrel of sand for single shot firing

Many people around these parts do. More secure and can form pods faster and take off faster as well. 1 person on each side, no problem!
Also I figured out a 10x10 plywood in the bottom of a plugged 3" HDPE tube is pretty safe if you just want to shoot a single shell or two.
