I had bought an ally windshield from ebay for use with meths stoves but it was far too tall to fit in a normal pouch and towered above the stove. I cut it in half after marking straight cut lines in marker with some tin snips then replaced the end ground pegs on the second one (could use the first one from the top half as bought) with some untwisted and snipped coathanger. I have now got two 5" folding screens for 10 minutes work. One in my response pack with Tatonka stove and GSI mug and one in my hexi cooker/pellet tin stove. Well pleased.
