Corretto roaster, or how to start roasting for less than $100.00

[Chris.]

Bump, cuz I was just watching vids of different ways to home roast. A heat gun and drill (both of which I already have) attached to some type of drum was my initial choice, but this may win me over too. at approx. 1/2 cup of beans per roast with a popcorn popper, it's really not enough.

How long do you let your beans rest between roasting and grinding/brewing?

I saw a couple tutorials say you should wait a couple days for the bloom to settle down a bit...
