Zeekster,
3/4 in, schedule 40 PVC and they are very sturdy, very light weight, easy to store, and cost me about $180 to build two manual launchers at home. We even go as far to make our own pouches. Cost about $25 to make 3 as compared to that for 1 from online. I got the tubing from
http://www.reefscuba.com . They have tons of different sizes and lengths you can buy.
Like I mentioned before, I'm electronically challenged so im still trying to deccifer everything the other threads say I need and how to put it all together, but I think I have it down.
- Door lock actuator (going to a junk yard to pull these off)
- 12V battery
