I had to do some brazing work in a really confined area. There was only 1 inch of clearance between the work and a thin plastic sheeting. Normally, I would have just dropped some scrap plate behind the area to protect from radiant heat damage. Because of the plastic, I was afraid that would not be enough of a shield, and re-radiated heat would melt the backing. So, I built this little do-dad. It's 6"x6" and 1/2" thick. The picture are pretty self explanatory. I put the tread side of the plate against the frame so that the space between the treads would make several exhaust ports along each side. It's not pretty, but I only have about 15 minutes and a couple dollars in it, so function won over form. Anyway, thought this or at least the idea might help somebody out and save stuff from getting burned or melted. Oh, it does use a LOT of air. SSS
