@rp181 Thanks I'll check it out.
I have no clue, lol. They have a bunch of stuff they don't need but have anyways. The city the school is located in has high taxes, I think that's why.
@big5824 That's exactly it. The coils will become smaller and smaller but the first one needs to not use to much power getting things started.

You could use a push type solenoid to initiate movement. This would be a far more efficient way to get the projectile moving. I don't consider it cheating because we are basically building a large unconventional solenoid anyways. It also allows you to use optical triggering for every stage.

I looked at their website and I couldn't find anything on custom solenoids. I was also interested in seeing if anyone had had any experience ordering custom coils from them. I saw the premade ones but they said they wanted $86 for one!! If that's the case I should get into the coil winding business.
An injection solenoid would work but I was considering using a pneumatic loading system for my final, polished design.

If you click on a specific solenoid and then click the "more information" button it will go to a chart of common gauge/turn# pairs for different applications(voltage + duty cycle). You will have to contact them to purchase any combination not available from their quick radio button menu, I would not trust selecting a different setup and leaving the actual desired parameters in the "Special Comments" box.
