UDS - Controlling Temp Spikes

[sjm845]

Nice mod my man. As soon as I saw it I knew that it would work! I did something similar when I made my own daisy wheel exhaust for my wal-mart kettle lid that really was the bottom of the grill out of 2 sheets of aluminum. If the concept works up there it should down below. I'm going to be in the lab this weekend trying to make it work. Thanks!

It's definitely a geometry project....had me using those skills I learned back in high school that I swore I'd never use. I used 15 degree cuts just because that divided nicely into 360 to give me 12 equal sized gaps. The top disc I ended up cutting the gaps out a little smaller so I'd have sufficient coverage when closed up. You can see in the pic that the top disc is a bit smaller in diameter than the bottom disc. That really isn't needed because I changed the support system to be an aluminum X that goes across the bottom disc which is attached to the eye bolt and supports it instead of the 4 bolts. The 4 bolts caused the areas not supported to sag a bit because I didn't use a real stiff steel.

So if I were to do it again:

Make the center of the disc a tad bit bigger for strength
Same sized disc on top and bottom
Use thicker gauged steel or aluminum (but remember it needs to be somewhat flexible in case it's a real tight fit getting it in based on whatever you use for the grill supports)
