Hello everyone.

I've been looking for a recovery machine in my part of the world, even a used machine is so expensive that I can't even think about buying one of those as of now.

So, I went about searching how can I build one myself

I have most of the things, including the compressor, condenser - piping is of course no issue...

but I need a general diagram of such a unit plus =
how to remove oil from the refrigerant?
what to use as sep tanks? - where to install the seperator tanks things like such

how to inject the recovering refrigerant into a cylinder

need general guidelines so I don't blow anything up

regards
