I believe Mortars are restricted weapons in NZ.

However Lobbing Canons are not restricted weapons.

I built a Lobbing Canon that will shoot two golf balls around 200 meters in height and around 400 meters in distance.

You mean a peice of pipe probably about 30 bucks with a threaded blank on one end.

I have a fal,shooting it off tahuna beach at haulashore island would be the problem

No where to use it Rushy, when i win powerball and buy some land I will give it a go.

This is the type of thing I have always envisaged, i'm 99.9% sure they are not restricted - If someone can point to the legislation that proves me wrong I would be interested.

I wonder if we can do a group buy if everyone is keen?

If that's a golf ball sized hole in there it looks very very short!

It similar to the coehorn mortar design.

Most of these are made using old oxygen bottles.I'd still be worried they would burst.Its probably only 1/4 inch thick.

"punkin chunkin" has a better following.You can grow the pumkins in a mold.

Trebochettes (spelling?) are wickedly cool

Give your Arms Officer a ring tomorrow and tell them your going to make a Mortar

Let us know how you get on.

In the meantime this is my Lobbing Canon



The barrel is machined out of 4140 and the base is 10mm mild steel.

How far can you get it with such a short bore Pete?

VC

The length of the bore is 100mm.

The powder chamber will hold 350grs of FFG

300 grs of FFG will shoot two golf balls around 400 meters.

But the idea with the lobbing canon is to shoot it high and try and land the ball closest to a mark.

At our canon shoot days we aim for 100m, closest to the peg wins.

Cheers.

Pete, that is really awesome. How much did that set you back?

There doesn't seem to be much different in the design between a coehorn mortar and a lobbing cannon.

Hahaha only subtle differences.

Cost me nothing but my time.

Everything was made out of off cuts destined for the scrap man.

The Boss was having a clean up in the workshop and let me take what I needed.
