First Gun Question

[dweave3]

Hi Guys, I'm new to the board and am trying to research some triggers to use for my first attempt at building my own gun. I plan on building a 60" rear handle gun, enclosed track, with 3 bands. I have read a lot about the Neptonic and Alexander triggers as well as the Kitto triggers. I have a few questions about them if anyone can help.

1) What type of shaft do the Neptonics need to be paired up with? Is there a certain shaft ex. JBL Riffe etc that have to be bought?

2) Do the neptonics have any sort of safety? If not which triggers do use a safety mechanism?

3)Any pair of trigger and handle pairs you guys could suggest?

Any suggestions would help me out.

Thanks guys

Might be worth doing a search for Neptonics & Alexander triggers, this has come up before. Hopefully one of the forums gun builders will find this & respond.

e.g. This thread mentions both: http://forums.deeperblue.com/diy-homemade/73029-trigger-mechanism.html
& this one has some useful links in it: http://forums.deeperblue.com/diy-homemade/82038-trigger-unit.html
