Re: Praise The Poo-poo!
My friend at work provided me with a length of 1" stainless flexible appliance gas line. I have not decided on the exact configuration of the bends but this stuff will be pretty simple to form to whatever shapes I need. The diameters are slightly mismatched so I will be machining some couplers to match everything up.
Also today I picked up a small 4 stroke muffler to help keep the noise down (not shown). I will either mount it as a stinger or put it in-line along the exhaust run. I's nice to have all winter for planning and design. Taking my time with things is really paying off.
Sorry about the mediocre pic, I will probably be doing more documentation as things become more permanent, and I will explain item numbers etc..
