Thought you guys might like to see how I replaced my WSN T-34 engine screen. I bought this metal screen package at Micheals Crafts. Wasn't very expensive and its enough to last a lifetime.

I cut out the original solid grill and thinned the edges. Superglue with accelerator got the grill in place. The frame work is some thin sheet metal I had laying around. The bolt heads are plastic rod cut offs.
