Washers in re-burn tubes

How did you reduce draft?

As for modding the secondaries I did it like this...

I bought a 1/2 inch baffle board and used the secondary tubes to cut into the baffle board effectively blocking the tubes then I drilled a 1/4 hole through the ends.

It has made a difference for sure. I'm still playing with it. The baffle board is a bit fragile though so I don't know how it will hold up over time. I might try to find something like metal washers to use instead.

That's ingenious.
