With the engine controls complete I began work on the exhaust system. I realize this is slightly out of order, but I thought it best to get the controls in first without the exhaust pieces in the way. I'll see how this goes. I began by modifying the exhaust support tubes by rounding off the top edge, then attempting to 'squeeze" the tubes in a vise to flatten them out. My vice is a clamp on aluminum one that I have used on 2 builds, but it wouldn't make a scratch on these stainless tubes. That's good news in a strange way. A friend of mine stopped by and offered his steel vice. That worked fine. I then fabricated the scat hoses by cutting them to length and modifying the wires per the plans.
