I've only run one batch through it, but trub settled just fine. The angle seems okay, it just all settles right into that 2" valve. On that first batch, I pulled trub about a week into the ferment, then a couple of days later harvested yeast.
I lost my second batch yesterday, though. It developed a leak. I'm not sure if the epoxy broke, or if I didn't have the lid sealed tightly enough. I'll take it apart to clean it tomorrow, so I'll figure it out then.
Pretty cool.
The only thing I'm confused about here is you said you didnt want to pay for one but spent $100 to build that. Do you know there are more than one 5 gallon plastic conical on the market for under $100 like the fastferment?
I admire the DIY spirit fully but $120 gets you a better version of that with no building, PVC, or bubblegum. The main problem with improvised fermenters, especially conicals, is that the surfaces and joints are near impossible to sanitize. If that did hold from leaking, I suspect you'd start contaminating batches after a few.
