A lot safer if you use PVC... Plus you can cap the end and use glue, not duct tape. Not to mention, spray the inside of the tube, and use a grill lighter thats glued in to the base to ignite. Launches potatoes hundreds of feet.
WOW... The tennis ball mortar that I built, fires like 6 hundred feet. We used right guard spray. It also sounds like a howitzer firing. All in All... yours is pretty good though. I would add another pringles can at the end as a barrel extension.
@MultiLordSam We used 4 pringles cans and taped them all together, like in the video. We also used a cardboard tube that newsprint paper comes on instead of pvc. to get the best launch blow in the front of the mortar and spray a little right guard. the drop in the ball, baseballs work the best, spray the spray in the back hole, like in the vid, blow a little more in the back hole, and then light over the hole. hint- wear ear protection =)
u have to clean it out after everylaunch just light thhe inside on fire and it will clean ours still works really good it will shoot straight up 100+ feet
So I didn't ask for the price, that was somebody else. However, I did figure out that Ronsonol Lighter Fluid is a good brand to use. Problem; I can't find any. The book says not to use butane based stuff so the options are really limited.
This is weak sauce Matto but you have potential... You should try using black powder, thick steel pipes and dense projectiles that hold more momentum.
to get a perfect circle i used something called a hole saw (look it up)( you put it on a drill and it makes a perfectally circular hole). And you need to put in around 1/2 teaspoon of lighter fluid but i think we used a LITTLE bit more. if you got 2 much then the cannon will explode.
ok i made one today u dont have to have a perfect circle but its fine also about 3 to5 sec spray in the barral also in the hole where the ignition is and shake then add projectile then lite
first cut holes in the bottom. i dont think it matters that they arnt perfect but they should be pretty close. then wrap it all in duct tape including the bottom. i used a whole role on mine. then puor in lighter fluid and try to get it to the bottom chamber. make a touch hole put the ball in and boom it up.
@mattto14 The diamater of the baffles, or " holes" as you refer to them are what make the mortar work. they should be about half of the diameter of the bottom of the can. Shitty baffles can ruin your mortar. I made a mortar today because i had nothing else to do and with a little extra work on the baffles made all the difference- I got atleast a 100 yards distance on my best shot.
okay, the best way to launch it as far as it can go, is 1. You can word your way up to 4 pringles cans, the two at the top where it comes out are just one long tube, no metal inbetween...anyway...cut the top off of a soda can, turn it up side down after the hairspray or w/e (i like rave or aquanet) then after the can is in there put in the ball and lauch, it is usually louder and it goes really really far. i'll try to post a video
I love the backyard ballistics book!
