Hi Jeff,

If the caps is the only thing missing for running your coil try
salt water cap really cheap to build Geek have good plan on there
site. Oil cap could be interesting but you will need a gigantic
one not easy to build and messy. Many of us used salt water cap
before they are lousy but easy to build cheap and relable. See
this link.
