You don't seem to understand, when you are retired,you must always keep busy on projects. No, no nothing to do with staying active for health purposes as you age. Self defense. My laptop dies yesterday and thought I would lay on the couch and watch DVd's. Something I haven't done in a while....the wife comes in and sees me relaxing and says " I need your help" 4 hours later...I could have used a good a excuse like I was working on the postal. But she see's the mail coming in.
Okay enough whining. Here's a muzzle disk. This disk took about 10 minutes to make and an hour to photograph. I made the whole thing with basic handtools.
I found an old yellow plastic coffee can lid that looked good. You could use a piece card board, plywood, old piece of floor tile what ever. You also need a wooden dowel that fits the bore loosely.
Measure the diameter of the rear of the cannon.
Scribe a circle on your disk material the same diameter as the rear of your cannon. I used dividers instead of a compass as the scribe marked the plastic and the lead of the compass wouldn't.
I used a magic marker to highlight scratched line and cut the circle out.
With circle cut out, I cut a piece of dowel off about an inch long. I squared one end and rounded the other. I went looking for a thumb tack and only found a push pin, so I had to make do.
I also added some cross hairs by cutting some strips from plastic tape.
Push the pin ththrough the disk and into the center of the squared end of the dowel. Insert the disk in the muzzle.
If you use the cross hairs here is how to align align them.
To aim the cannon us the disk as The front muzzle swell and follow instructions in
Aiming a Cannon without sights, South African style .
