Tubing runs for pitot, total energy, and static lines from probes in stabilators to instruments. Straightened three 10 foot lengths of 3/16" OD aluminum tubing from coil by using the method in this Youtube video. Put tubes inside a length of PVC conduit to prevend bending while feeding tubing through grommets in bulkhead web. Forward through holes in bulkhead web drilled with closer spacing than plans to accomodate prep and riveting of box.
