Thanks fellows.
Back to the air filter. It's pretty much done except for a couple of screws to hold the cover on. I didn't like the first idea of using a shower drain cover because it started looking like a lawn mower muffler, so I bought a cheap Kitchen sink strainer and cut the screen out of it. It had the basic shape and all I had to do was reshape it a little and add a couple of dents to knock the new off of it. I also soaked it in some muriatic acid to take the shine off of the stainless screen. I used a torch and burned the paint off of the housing which left a nice bare metal finish.
I've been looking for some filter material to stuff inside of it like lawn mowers use, but so far all that I've seen is green. I'd like to find some black or grey. Any ideas?
What about the material used in crank case breathers mounted on old cars valve covers?
Here it is, two dollars later...
Here's the thrift store candle holder that I started with...
This is the plastic cover that came with the kit...
