Build a potato luncher with 2" pipe to put whole sardines and cast after second sand bar from beach for big creatures.

It is very good and cast 200 yards it will be 2" by 10" when loading it. Cool addition for salt water fishing. Actually I can change the caliber to 1" and make bait for catfish and use in lakes  I am uploading one of my shoot and ill share in in few.

I would check with the county lifeguards before you fire that thing, maybe some rules re: shooting something like that on public beaches..?

Can you say Bait fish confetti ?

I can.

Good Luck

Nice! Learning to make one of these has always been on my bucket list. 

Anything left to the bait?

I built one when I was 17. They’re easy to build pretty inexpensive and a ton of fun. Watching a potato fly at Mach 2 and a couple hundred feet never gets old! ?

His lunch.  It says so right in the thread title.  Potato Lunch.

The trick to using a launcher to launch baits is to have them pre-rigged. You freeze your bait weight and all in a water filled tube of the correct diameter and making sure to connect the line prior to launch is a good thing. Don't ask me how I know.

What is the propellant?  

We used to use aerosol hair spray haha. Fun times

Just pack them into a sabot.

I used carb cleaner for the fuel and used a grill spark igniter and JB welded it to the back and that was my ignition.

Judging by what @ATA has in his picture, I’d say he’s using compressed air. 
 

I’d venture to guess the fish prefer their bait a little on the cooked side versus cold. ?

A stop sign is no match for a firm tater at speed. So I've heard.

I also used hairspray. My trigger was a twist ignition from an old Coleman lantern. 

WD-40 and Nitrous Oxide.   Nitrous Oxide is just an oxidizer.  It needs something flammable to work with.  That's where the WD-40 came in.    We learned really quick to wrap our "tater guns" with duct tape.  The kept the pieces together when they exploded instead of thrown shrapnel at us.   We'd wrap the taters, or apples in a rag.  This kept them from disintegrating when they came out of the barrel.   Kinda like the wadding in a shotgun shell keeps the shot together.   

 

I made one of of schedule 80 pipe and was going to try acetylene but changed my mind.  We used to make acetylene balloons and shoot them with a .22.  Someone showed me an article about someone getting killed while filling a balloon with acetylene.  Static electricity caused it to ignite.  Don't mess with acetylene.   

 

All of this was ~40 years ago.
