1" bore. 500 gr. Fg.

Tube is seamless, forged (drawn over mandrel) steam tubing. 3/4" wall. Breech plug is pressure fit welded, bead fillet weld, flush to touch-hole 2" deep.

1.125" dia. trunnions, jigged and welded.

Carriage is salvaged red oak from an old desk.

Wheels are some sort of hard plastic stock I found at the local marine supply. They just happen to be machine faced and uniform width with centers located for boring to fit axles.

1/2" steel axles from round stock, drilled for cotter pins.

Trunnion caps are 1/8" X 1" mild steel strap, cold hammered to shape. (That was tricky!)

Quoin rails are 1/8" angle iron.

Stainless eye screws w/ annodized washers, brass rings.

Mostly we shoot "salutes" with blanks, but it shoots 3 oz. lead "cannon ball" sinkers (From the marine supply), C-cell batteries, nuts/bolts, nails, coarse gravel, ball bearings . . . Smooth bore and not prone to bore bruises.

When I was a kid in Boyscouts, one summer I took part in a mountain men experience camp. Every day we were woken up at 6 am to the sound of a small cannon just like that.

Your pics just brought back some good memories, learned to shoot blackpowder that summer. Nice cannon!

Never have fired it for "range/accuracy." We did shoot it at a pallet we fixed up from the John Deere shop -- 2 X 4 laid like "brick work" staggered on the pallet, three deep -- About five inches when you figure for planing and finishing on a 2 X 4.

It blows a big hole, and takes a lot of the board along with it. Overlaid boards tend to break out the others around it.

Makes a big ditch in the dirt berm backstop.

But mostly it's a "salute cannon." And sits on the coffee table, because it's like decor. :D

I have a 3/4" bore cannon that my brother and I built as a scout project, many years ago. We bought the barrel from Dixie Gunworks for $15, also bought a 69cal scissors mold at same time. With 12Ga wads for sabots and measured 150gr loads, we could fire into a trashcan lid about 18" consistantly at 50yds, once we got on target. We found the 69cal ball very inaccurate without a sabot; too loose I guess. They're great fun and a hoot for holidays. The barrel is 14" and is cast iron. I'll try to post a picture when I get my camera back.
