7 hours.<\/p>\n
Yes, I’m using a Nitzer Ebb track as a title. Yesterday before the grand face-stuffing of Thanksgiving, I fabricated the bracket for the purge valve. I don’t work with steel much, but 14ga hot-rolled sheet steel isn’t too bad. My bandsaw blade would disagree, I think it’s just about shot. I also killed my grinding wheel. Now that I’ve used it on steel, it’s useless for aluminum. But that little exercise has taught me not to fear steelwork. Not too much at any rate. <\/p>\n

\nHere’s the bracket. The cable goes across the engine to work the purge valve arm.<\/p>\n
So today was all about measuring for control cables. Van’s has a 60″ push-pull quadrant cable that should work for throttle, mix, and prop governor control, and ACS has a button-lock cable that should do for the fuel purge. I needed a 65″ cable for the purge, but ACS doesn’t sell one less than 6 feet, and I don’t feel like having a custom cable made for that stupid thing. I’ll make a 72″ cable work.<\/p>\n
I also went into a mad panic thinking I’d forgotten to write down the wiring map for the AP servos. I looked for the Trio\/MGL wiring instructions for about two hours, because I seem to remember writing the servo-to-cable-to-DB9 colors and positions down on it. I couldn’t find it. After looking everywhere, and thinking I was going to have to reverse-engineer the wiring from what I could see in the clear-shrink-wrapped bundle on the pitch servo. <\/p>\n

\nBut no. I tacked it to the wall above the workbench and didn’t think to look there.<\/p>\n
With cables measured, I measured the lengths for the remaining hoses I need. I need one for oil and three for fuel. I put in a quote request to PHT, hopefully they’ll be able to turn them around fast.<\/p>\n","protected":false},"excerpt":{"rendered":"
