That heat deflector plate will tend to warp and want to move with the heat. It depends upon the thickness of the material you used. The spaces are to maintain a minimum and uniform air gap. The air gap is what gives you insulation for heat dispersion. I put mine in with 3/8 stock as spacers, bolted in with hardened cap screws, automotive exhaust manifold springs (cut down) to take up slack and stop a rattle.
You got allow for some movement since there will be temp difference between deflector and anchor point. This would be especially true if you used two different types of steel. I made mine removable so I could remove / modify it. It is easier to do that now while it is easy to get at.
Take a look at my build thread....Dave O gave a good explanation of what to do. Thanks again Dave...he has really helped me out!
Keep up the work....you'll get her done......odd hours or not!!
