That's a great idea George! Wish I'd have thought of that. I happen to have some scrap expanded metal lying around.....I had one of those cheaper chimneys that the grate was giving out. So I just cut a piece of expanded metal and jammed it down on top of the old grate and it has worked fine so far. I just don't give up on stuff I spent money on till it crujbles !
Just got one in the mail today too, I take the SJ camping and find the bigger one takes up too much room.
