Hey, anyone out there own one of those huge Oasis compressors? You
know, the one with the winch motor hooked up to the York compressor?
Model HP1000 or XD2000

I'd like to build one, but I don't know what's in the "little black
box" that fits between the motor and compressor. Is it a direct
coupling? Is it a gear assembly? What?

Anyone know? got any pictures?

any help is appreciated.

thanks
