Thanks to Lee Putman i got the heaters cheap and finally got it wired. Heres the results. I used a old electrical box to mount all controls in and on.This is the starter box for a 5 horse rix compresser which goes to 4500 psi.
i had a friend put together a control air panel with 2 fill whips.. I also have a bauer compresser mounted next to it with the upper box controlling it. Now I'm set to fill tanks when the ocean calms.

Its the bottom box in this photo
The rix oiless system
air panel with high pressure regulator (4500 psi) step down
all compressors with large air bank tank and fill whips-one noisy corner in shop.
Most items have been picked up second hand-tanks -compressors-some controls-lots of high pressure stuff from Boeing surplus-one of the great as is yards.
