Louche no matter what

[JuanFlaco]

I would really apreciate some help here... I managed to build my DIY still with a beer keg, a 2 inch column 70cm tall and a copper worm, using it as a pot still by heating it with the kitchen stove. It works pretty much according to theory. The thing is that after my fourth run attempt, the product always comes cristal clear but after i make my cuts and dilute to 80 or 90 proof it comes cloudy. That happened with corn whisky twice, and also brandy and even sugar wash. Right now I'm fermenting a new sugar wash to try again, but I'm not sure of what I'm doing wrong. I already made a vinegar run, eliminate anything that's not metal in the vapor path, runing it slowly etc and couldn't solve it

Thanks!
