I received my eBay reducers today. I have three now. The first I bought is from Dan636 on here. It is the same one made of brass in Elfster's videos. Very well machined and threaded both inside and out. The ones from Ebay are not threaded and are smooth on the inside. , I wrapped them with teflon and they screwed right in. The Ebay reducer is a set of two different sizes both of which are bigger than the brass one. All three seem to be good to go.

I also installed 3 panels as seen below, back, left and front. My setup sits on the far left of my bench and it made more sense to work from the right side. Eliminated all draft issues and so far I haven't bumped the trickler. In fact, it is a non-issue, I don't even think about it being there when I place the cup. The other thing I did was put the clear plastic cover back on the scale, that combined with the weight of the 419 lid made the top more stable.
