January 21, 2008 - A single cut and twist on one of the tubes solved the interference problem with the collector.
Now, time to build the next runner. After some more grinding and massaging to make it fit with the final collector location, I welded it together. And almost screwed up in a big way!
After building the #3 runner, I tack-welded it to the flange - and was smart enough to test-fit the #2. Whoops! While welding the #3 runner, I removed a short spacer that I'd inserted. You can see it in the background of the last picture. I thought it had been put there to make the tube fit a bit better and my slightly reworked setup just improved the fit. But I'd forgotten it was also there to give enough room for the #2 tube to pass underneath! Also, if I kept going in the current order, I'd never be able to weld one of the #2 seams all the way around. So off came the tack weld and now I can assemble #2 without causing problems. That was close.
