A barrel design you don't have to worry about...
« on: May 17, 2008, 06:20:17 AM »
Hog it out of steel.  This 8-inch mortar tube weighs 1400 lbs.  Trunnion shaft is welded to tube with about 5 lbs. of rod.  It isn't mine.

:o Now that had to be one heck of a lathe!
by the photo's it looks like there is no reduced chamber..... or is it full of water?

Is it for sale?

Chamber has water in it.  It is a perfect cone about 8" from large end to point.  That's not realistic of course, but it is a chamber and the tube reportedly does shoot well.  I think I heard it was sold recently.

Kind of a strange mount for an 8".

Solid steel, can't go wrong. 

Yes the bed on the 8" is unusual, looks like they sorta kinda tried to imitate the cast iron 8" M1841 bed, but in wood.  Since they were target shooting at max 200 yards, they got away with it.  That wooden bed would not hold up with max charges the 8" M1841 would take.

     Our thoughts on this type of construction run along the same lines and they are:  "Solid steel, can't go wrong."  ...................Yep.

Yes, compared to the one above it and can probably fit inside the bore.  ;D  If my measuring is correct, the mortar cannonmn posted has a 4" thick wall.

Dom,

You could build them a custom sub caliber insert out of you mortar so they can conserve powder during practice........ ;)

I can imagine it would be fun installing a vent liner in that.  16" OD x 1" powder chamber.  That would be a 7"+ liner.
