Spud cutter

Unread postAuthor: neospudgunner » Sun Jul 13, 2008 9:29 pm

My grandpa and I recently built a spud gun, the old fashioned hairspray kind, and were wondering is there any way to make a cutter for the spud other than just shoving it down the barrel? Here are some pics of the cannon...

Holy crap! That is very cool. Yes, there is another way. Just take a section of pipe that is the width of your barrel, and sharpen it at the end. It doesn't have to be that long.

EDIT: YES! first post.

BTW, the cannon looks great! What did you make the cannon out of? Wood? Obviously the fixture, but I mean the cannon itself.[/url]

Looks like several 2" thick foam disks sandwiched together around standard PVC to me. Very cool Neo!!! Certainly captures the cannoning spirit. A great show piece if ever I saw one.

If you had used SDR 21 1.5" pipe you could have shot golf balls instead of fooling with taters. Did you get any pics before you encased it?

Great job overall, A+.

First off thanks for the praise! Second the cannon itself is made of 2" pink insulation foam and the larger rings are made of 3/4" pink insulation foam. Third the carriage is wood...mostly redwood and pine to be exact.

I can barely see in the pics, it looks like there's a mechanism that raises/ lowers the barrel. Also what does the the cannon itself look like, is it just a length of 2 of 1.5," what are the specs?

Great cannon there!
Is the ball on the back attached through the end cap?
Nice job. Your grandpa must be cool. 8)

Koolaidman - i think you're talking about the little wedge in the back, right? All that is is a wegde of wood with a handle on it. The actual potato cannon is 46" long consisting of 13" of 3" PVC and 30" of 1.5" and then of course the end caps and adapter adds 3".

THUNDERLORD - Yes the ball on the back is attatched to the end cap. My G-pa turned that on his lathe. Yeah, he's a pretty cool guy. And what's funny is that he suggested making the cannon inthe 1st place! :shock:

This must be the most elaborate hairspray cannon I've ever seen :D

Great job on it even down to tidying the igniter away into the carriage.

Wow! You and your grandpa did a spectacular job. I love how it has almost every aspect of a real cannon (great way to throw people off if they don't know it's a spray n pray). I bookmarked this page for reference for some ideas on my T-shirt launcher I am working on for my school.

About how long do you think it took you and your grandpa to make this cannon? *Including buying and preparing supplies..
You guys are pretty smart not using Styrofoam to make the exterior shape of the cannon (that would have been my first intention) cause if you did, you would be stuck with it white cause you all know what happens when you combine Styrofoam and spray paint....

Again, very nice work. I can't wait to see your next project/s.
