I built it, but it went 10 feet. I think I did it wrong.

you could've used less pieces on the base. I made my own base that uses less pieces and still works great.

how far does it shoot??????

Pretty cool. Too bad it only uses small rod ammo instead of a bigger caliber. It would be great if someone made a mortar that could launcher either IaC's War Bombs or my X8D Suplody for a devastating effect. This is still really good though.

im gonna make a knex mortar and put my very own knex grenades as ammo so it can have more of a devastating effect.

Jan 13, 2009. 10:31 PMDrWeird117 says:

I modded this to fire I_A_C's ammo, plus, you drop it down, and it automatically fires, like the real one.

Feb 22, 2009. 12:38 PMmega man 4bm says:

Mind if i post a sniper/cannon this with this design cause it has insane power and pain (and its silent until it hits its target!!).

how far can it shoot

Nov 15, 2008. 2:45 AMKILL-BOT 1 says:

tis very good,so well done, but the trigger is wrong. the way a mortar works is when you drop the ammo into the tube, the impact sets-off a percusion cap connected to a charge. the charge blows up and sends the ammo flying. when I was making my mortar I tried to make it so to fire I had to pull back the bands to the trigger. I would the drop the ammo in, releasing the trigger, sending the ammo flying. I failed to do this... you should give it a go.

Nov 16, 2008. 5:14 PMsniper crazy says:

it is very difficult to have a self triggered knex knex like that u need an extremely large barrel and u might need to use something else as the ammo besides knex

Nov 19, 2008. 11:09 AMKILL-BOT 1 says:

no, knex ammo would do... all you need to do is have te trigger release inside the barrrel so when the ammo is dropped in, the trigger is released.

Nov 16, 2008. 5:15 PMsniper crazy says:

it the mortar would consume atleast 900 or more peices that not a lot of people have

Nov 16, 2008. 5:15 PMsniper crazy says:

if*

Oct 19, 2008. 5:28 PMjaghead 96 (author) says:
