Afternoon delight!

[Cat Whisperer]

Took a friend and his two boys out to fire 4 mortars this afternoon.  Here are a couple of pix.  The first one is of Bill moving in close to get a  movie of the 7.5 lb chunk of concrete.  Three mortars in the pix - left is the 1144SP golf ball 2 caliber long tube, a 4140 cnc golf ball caliber and the 4.55" (4" pvc pipe) coehorn.

Some pictures and comments:

This is my second golf ball caliber mortar using the 1144SP DOM and rounds.  (The first was fire-cracker powered.)

This tube is bored to 1.695".  TOO SMALL!  It fired ok, but after the FIRST shot the fouling demanded assistance to seat the next golf ball to the bottom of the tube.  

It's rude, crude and simple.  Bore is 2 calibers deep.  Powder chamber is about 1/2" in diameter and an inch deep (holds 50 grains of powder).

50 grains of GOEX fffg will toss the ball way into the woods (over 100 yards).  Low pressure - not much of a report.  Good velocity - hard to catch a glimpse.

Base is a thinned down piece of 4x4 treated post.  Notch hand carved and then a little 5 minute epoxy to glass bed it.  (Make sure you use mould release agent on the tube.)
