Hi Dave i have only done one roast in my popper so not much info to give you.
but my attempt at a chaff collector as in this thread had a 75% collection rate (approx). I reckon a flywire or two colanders wired together would work well. My foil collector was double walled and had lots of little holes punched in it with a skewer to let the air pass through.

one trick you need to sort is how to get the beans out of the hopper fast. Disconnecting your chaff collector may be an issue in this, unless it is really well attached. i just tore mine off the side and tipped them out. i used some little bits of paper to test my collection system
bewarned the popper is very HOT!! i burnt my finger

after my 1st attempt i will not be roasting inside again, it is a really strong smell. I will just roast outside and not bother with any collection. My Chaff was more like flyash from a bushfire (not burnt) but very light and floated / blew around.
Have fun, take some pictures
