I always seem to need more counter space when cooking. I'm jealous of the little folding extensions I've seen that have been added to the end of the cooking area some have built.
In the end, I just made a grate from a cheap cooking grill from the mega mart. I cut it down to fit. I bought some ¼" ID tubing to protect the end from scratching the faucet base. To keep the grate from slipping around I bought some fender washers, some round head machine screws, some nyloc nuts and plastic thread protectors so the thread ends wouldn't scratch the sink. The hardware is all stainless. I see the thread protectors as some local hardware stores.
I can set hot pots on it, I can pour through it and I can quickly set it aside if I need the full faucet height.
Lots of people have these. I didn't invent any of this, I just have an accumulation of pictures on a thumb drive in my briefcase. I'll stop now.
